PART I

ITEM 1. BUSINESS

Overview

Resonant is a late-stage development company that has created an innovative software, intellectual property, or IP, and services platform that has the ability to increase designer efficiency, reduce the time to market and lower unit costs in the designs of filters for radio frequency, or RF, front-ends for the mobile device, automotive, medical, internet-of-things and related industries. The RF front-end, or RFFE, is the circuitry in a device responsible for analog signal processing and is located between the device’s antenna and its digital circuitry. The software platform we continue to develop is based on fundamentally new technology that we call ~~Infinite Synthesized Networks®~~WaveX™, ~~or ISN®,~~ to configure and connect resonators, the building blocks of RF filters. Filters are a critical component of the RF front-end used to select desired radio frequency signals and reject unwanted signals. Our ~~ISN®~~WaveX™ platform allows us to develop unique, custom designs that address the increasing complexity of the RFFE due to increasing bandwidth requirements, such as by using carrier aggregation (the combining of multiple frequencies into a single data stream to increase throughput through higher data rates), or CA, by both reducing the size of the filter and improving performance. Our goal is to utilize our ~~ISN®~~WaveX™ platform to support our customers in reducing their time to develop complex filter and module designs, to access new classes of filter designs, and to do it more cost effectively. Additionally, our ~~ISN®~~WaveX™ platform has allowed us to expand our customer focus beyond just filter manufacturers by enabling a new class of customer - fabless filter manufacturers. These companies do not have their own internal filter fabrication facility, or fab, and typically already would be supplying other products in the RFFE to the original equipment manufacturers (OEMs), and, as a result do not require a protracted new vendor qualification process in order to supply parts. Through our existing customer relationships, we are able to leverage our ~~ISN®~~WaveX™ tools to deliver cutting edge filter designs to these fabless filter manufacturers.

We are commercializing our technology through the creation of filter designs that address the problems in the high growth RFFE industry created by the growing number of frequency bands in mobile and other RFFE enabled devices. The worldwide adoption of Long Term Evolution, or LTE, as the global standard, the transition to 5G, and the use of mobile devices to access the Internet, has resulted in massive proliferation of frequency bands which, when combined with CA for higher data rates and multiple input multiple output, or MIMO, has resulted in an ever-increasing number and complexity of filters in the RFFE. We have developed and continue to expand a series of single-band designs for frequency bands presently dominated by larger and more expensive bulk acoustic wave, or BAW, filters. We are also developing multiplexer filter designs for two or more bands to address the CA requirements of our customers. We are using our ~~ISN®~~WaveX™ platform to efficiently integrate these designs into RF modules for our module customers. Currently, we are leveraging ~~ISN®~~WaveX™ to develop these designs targeted for either the Surface Acoustic Wave (SAW) or Temperature Compensated, Surface Acoustic Wave (TC-SAW) manufacturing processes. In 2018 we further extended ~~ISN®~~WaveX™ for BAW designs, which has resulted in our invention of a resonator structure based on a combination of interdigital transducer (IDT) and piezoelectric membrane, which we call XBAR®, which exhibits performance parameters suitable for 5G, WiFi, and ~~WiFi~~UltraWideband (UWB) applications - high frequency operation, large bandwidth and high power reliability. Our success with XBAR® is dependent on our ability to develop high frequency filters utilizing these resonator structures that are successfully adopted by our targeted customers, which will be determined by our ability to show improved performance over competing products or significantly reduce the size and cost of their products.

We believe licensing our designs, either as prepaid royalties or royalties paid as products ship, is the most direct and effective means of validating our ~~ISN®~~WaveX™ platform and IP to address this rapidly growing market. Our target customers make part or all of the RFFE. We intend to retain ownership of our designs, and we expect to be compensated through license fees and royalties based on sales of RFFE filters that incorporate our designs and leverage our ~~ISN®~~WaveX™ platform.

Our customer engagement process typically begins with the execution of a ~~Joint Development Agreement, or JDA, and~~ License Agreement, or LA, for specific bands. Depending on the complexity of the design, we estimate that initial samples of products to OEMs, will occur typically within nine to thirty-six months following execution of a license agreement. ~~We classify these new designs as either ISN® Ready (9-12 months), ISN® Pilot (12-18 months), ISN® Advanced (18-36 months) or ISN® Development (Custom).~~ Following these development cycles, designs are manufactured, qualified by our customers and sampled to OEM customers. Our customers can take from three to six months to qualify a design and then the OEMs can take an additional three to six months, or longer, to qualify a design as fit for use, reliable and ready for mass production. The point at which an OEM begins taking product from our customers in mass production is typically when royalty revenues would begin. Our customer agreements typically provide for upfront design fees and royalty payments for each unit sold using our filter designs and typically last for a minimum of two years, but may be renewed for a longer period. More recently our agreements have included pre-paid royalties, which can be fully paid-up for a design, or a partial pre-pay with subsequent royalties when the part begins shipping.

In 2017, in order to further facilitate our fabless filter program, and to provide manufacturing stability across the supply chain, we embarked on the creation of our Foundry Program. Foundries joining Resonant’s program first complete a foundry evaluation process to ensure alignment with our customers for filter performance, manufacturing quality and capacity, and business practices. Once the evaluation is completed, the foundry runs a characterization lot, used to create a foundry process design kit, after which we are ready to start designs for manufacture in the foundry. Packaging/Back-end vendors can also join the program by completing a back-end evaluation process to match their capabilities with foundry partners and our customers. Through this program we enable a secure supply chain for all our customers.

In 2019, we began development of Filter IP Standard Library designs to enable faster time to market for our customers. Further, the first Filter IP Library design was incorporated into Cadence Design Systems, Inc.'s AWR design suite, allowing module designers access to Resonant filter designs. At Mobile World Congress we showed the first 5G filter based upon XBAR® technology - an n79 filter. Subsequently, we accepted a $7.0 million investment and signed a commercial agreement for the development and license of filters for four bands based on XBAR® technology, with Murata Manufacturing Co.,Ltd. ("MMC"), the industry's largest provider of filters for the RFFE. The commercial agreement provides for our receipt of up to an aggregate of $9.0 million of contract consideration in the form of "pre-paid royalties" for the licensed designs and certain other intellectual property developed in the collaboration, payable in installments over a multi-year development period, with each installment conditioned upon our achievement of certain milestones and deliverables acceptable to our customer in its discretion. During 2020, we continued the development of filters under the commercial agreement, resulting in completion of the second milestone ahead of schedule in October 2020. This milestone is significant as it recognizes achieving predetermined target performance, packaging and initial reliability. Completion of the milestone also resulted in the second payment from this customer. WeIn ~~have~~September 2021, we entered into Addendum 1 to the commercial agreement, which amends and supplements the agreement to provide for the development of XBAR®-based designs for up to four additional bands. For rights to these additional bands, the customer has agreed to pay us a $4.0 million non-refundable upfront payment and up to an aggregate of between $8.0 million and $36.0 million in prep-paid royalties and other fees, with the amount of the aggregate payments determined based on the complexity of the filter designs selected for development. In October 2021, we entered into the first statement of work under the amendment for a total of $7.0 million for the development of an additional band. We received a total of $411.5 million from ~~this~~MMC ~~customer~~ as of December 31, ~~2020~~2021. In accounting for this contract under ASC 606, we have determined the total contract consideration is to be recognized over time as the intellectual property is developed.

~~Early~~In in2021, ~~2020~~ we ~~signed~~continued ~~multiple~~to ~~new~~develop ~~license~~XBAR®-based ~~agreements with a major foundry focused on the China market~~filters, ~~further enhancing our foundry program. These agreements include~~ both ~~pre-paid royalties and royalty payments due upon shipment of parts~~ for the ~~licensed~~mobile ~~designs.~~market Inin ~~August~~collaboration ofwith ~~2020 we demonstrated that XBAR® based filters could be manufactured using standard SAW foundry processing~~MMC, aas ~~much~~well ~~simpler~~as ~~and lower cost process than is used~~ for ~~other~~the ~~BAW~~non-mobile ~~filter manufacturing~~market.

We plan to continue to pursue filter design projects with existing and potential customers and other strategic partners. These types of arrangements offer complementary technology and market intelligence. In addition, we will continue to help develop a fabless filter eco-system to support the growth in filter volumes for our customers. We ~~are also investigating the potential of licensing part or all of our ISN® software design suite to potential customers in the RFFE industry. We~~ will continue to develop XBAR® technology for both mobile and non-mobile applications, including 5G, WiFi and Ultra-WideBand (UWB) applications, forming strategic partnerships with filter manufacturers and customers to bring the technology to market as quickly as possible. We intend to retain ownership of our technology, software, designs and related improvements. Our goal is to establish and leverage alliances with new and existing customers, who will help grow the market for our designs by integrating them with their own proprietary technology and products, or by using our software products for their own designs, thus combining their own particular strengths with ours to provide an extensive array of solutions.

Merger Agreement

On February 14, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among Resonant, Murata Electronics North America, Inc., a Texas corporation (“Murata”), and PJ Cosmos Acquisition Company, Inc., a Delaware corporation and wholly owned subsidiary of Murata (“Purchaser”). Murata is a wholly-owned subsidiary of MMC.

Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, on February 28, 2022 Purchaser commenced a cash tender offer (the “Offer”) to purchase all of the outstanding shares of Resonant’s common stock, par value $0.001 per share (the “Shares”), at a purchase price of $4.50 per Share, net to the tendering stockholder in cash, without interest and less any required withholding taxes (the “Per Share Amount”). Upon successful completion of the Offer, and subject to the terms and conditions of the Merger Agreement, Purchaser will be merged with and into Resonant (the “Merger”), and Resonant will survive the Merger as a wholly-owned subsidiary of Murata. At the effective time of the Merger (the “Effective Time”), each outstanding Share (other than Shares held by (i) Resonant, Murata or their respective subsidiaries immediately prior to the Effective Time and (ii) stockholders of Resonant who have properly and validly perfected their statutory appraisal rights under the Delaware General Corporation Law (“DGCL”)) will automatically be converted into the right to receive the Per Share Amount on the terms and subject to the conditions set forth in the Merger Agreement.

Table of Contents

The initial expiration date of the Offer is the time that is one minute following 11:59 p.m., New York City time, on March 25, 2022, subject to extension in certain circumstances as required or permitted by the Merger Agreement and applicable law. The Offer is subject to the satisfaction of customary conditions, including, among others, that (i) at least that number of Shares validly tendered and not withdrawn (other than Shares tendered by guaranteed delivery where actual delivery has not occurred), when added to any Shares already owned by Murata or any of its controlled subsidiaries, if any, equal a majority of the outstanding Shares as of immediately prior to the time at which Purchaser first accepts for payment the Shares tendered in the Offer, (ii) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (iii) the other conditions set forth in Annex A to the Merger Agreement have been satisfied or waived.

The Merger Agreement contemplates that the Merger will be effected pursuant to Section 251(h) of the DGCL, which permits completion of the Merger upon the collective ownership by Murata, Purchaser and any other subsidiary of Murata of one share more than 50% of the number of Shares that are then issued and outstanding, and if the Merger is so effected pursuant to Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger.

The Merger Agreement places limitations on Resonant’s ability to engage in certain types of transactions without Murata’s consent during the period between the signing of the Merger Agreement and the Effective Time. During this period, Resonant may not raise additional capital through the sale of securities or incur debt. Further, other than in transactions in the ordinary course of business or within specified dollar limits and certain other limited exceptions, Resonant generally may not acquire other businesses, make investments in other persons, or sell, lease, or encumber our assets.

The Merger Agreement contains certain termination rights for each of us and Murata. Among such rights, and subject to certain limitations, either Resonant or Murata may terminate the Merger Agreement if the Offer is not completed by June 14, 2022, which date may be extended to August 14, 2022 under certain circumstances. The Merger Agreement also provides that upon termination of the Merger Agreement under specified circumstances, we may be required to pay Murata a termination fee of $11.2 million or Murata may be required to pay us a termination fee of $15.0 million. In addition, upon termination of the Merger Agreement under specified circumstances, we may be required to reimburse Murata for up to $3.0 million of expenses. Any expenses we reimburses Murata would be offset against and reduce the amount of the termination fee otherwise payable by us to Murata.

Additional information about the Merger Agreement is set forth in our current report on Form 8-K filed with the SEC on February 14, 2022.

No statement in this Annual Report on Form 10-K is an offer to purchase or a solicitation of an offer to sell any shares of the common stock of Resonant or any other securities.

Industry Background

Glossary

The following is a glossary of useful terms:

•4G—4th Generation is a mobile communications standard intended to replace 3G, allowing wireless Internet access at a much higher speed.

•5G—5th Generation is a mobile communications standard and is the latest iteration of cellular technology, engineered to greatly increase the speed and responsiveness of wireless networks.

•Band, channel or frequency band—a designated range of radio wave frequencies used to communicate with a mobile device.

•Bulk acoustic wave (BAW)—an acoustic wave traveling through a material exhibiting elasticity.

•Duplexer—a bi-directional device that connects the antenna to the transmitter and receiver of a wireless device and simultaneously filters both the transmit signal and receive signal.

•Carrier Aggregation (CA)—the aggregation, or adding together, of multiple carriers (frequency bands) to meet the LTE-Advanced specification requirements, allowing for increased transmission bandwidth delivery of higher data rates, improved capacity and more efficient use of a carriers fragmented spectrum.

•Filter—a series of interconnected resonators designed to pass (or select) a desired radio frequency signal and block unwanted signals.

•WiFi—a wireless networking technology that allows devices to interface to the Internet.

•Ultra-wideband (UWB)—a radio technology that uses very low energy signal for short-range, high-bandwidth communications over a large portion of the radio spectrum.

The Mobile Internet

The need for multiplexers, duplexers and other filters in the RFFE of mobile devices continues to grow rapidly due to rising consumer demand for always-on wireless broadband. Mobile devices such as smartphones and tablets are quickly becoming the primary means of accessing the Internet. According to Cisco, there were 8.8 billion wireless devices in 2018, predicted to grow to 13.1 billion by 2023. To accommodate the increase in data usage, Cisco also predicts that WiFi hotspots will increase from 169 million in 2018 to 628 million by 2023.

The exponential growth in mobile data traffic is testing the limits of existing wireless bandwidth. Carriers and regulators have responded by opening new RF spectrum, driving up the number of frequency bands in mobile devices, with many of the most recent allocations being at higher frequencies than in the past, and of much wider bandwidths, thus pushing mobile phone designers to make more efficient use of spectrum.

According to Navian Inc., the market for RFFE filters in mobile devices was 45.5 billion filters in 2019 and will grow to an estimated 72.0 billion filters by 2024.

In addition to RFFE filter unit growth, filter sales growth is expected to follow and was estimated to be $8.0 billion in 2019 and is forecasted to reach $12.2 billion by 2024, according to Navian.

Adding RF spectrum to increase capacity and data-rate is not a complete solution. The added spectrum for 4G does not come in large contiguous blocks, but rather in small channels or bands of varying size and frequency. Thus, more data means more bands, and the result is a rapid and substantial increase in the number of bands in mobile devices. 5G introduces new challenges for filter performance and complexity, by adding much larger blocks of spectrum at higher frequencies (above 3GHz).

Challenges Faced by the Mobile Device Industry

The world is progressing toward ubiquitous RF coverage in which almost all devices will be connected, most wirelessly. Technology experts predict that by 2023 there will be over 29.3 billion connected devices operating worldwide and we will be measuring mobile usage in Exabytes. This overwhelming demand for wireless data has driven the carriers and regulators to open new spectrum bands.

This substantial and rapid increase in bands has created several significant problems, including a corresponding increase in the number of filters and duplexers in mobile devices. Traditional RF front-end solutions typically require one duplexer for each frequency band. The ~~most~~iPhone ~~recent~~13, ~~iPhones~~model ~~support~~A2481, supports coverage for 2224 FDD-LTE and 8 TDD-LTE bands, in addition to support for previous wireless technology generations, 3G and 2G, and most recently 5G coverage for sub-6GHz and mmWave. Each band requires a filter, either as an individual filter, a duplexer or a multiplexer, depending upon the spectrum and CA requirements. This increase in number and complexity of filters is dramatically driving up the cost of RF front-ends. In the latest global smartphones, filters, duplexers and multiplexers comprise more than half of the cost to the RF front-end, according to Mobile Experts. The dramatic increase in the number of filters required, which includes Chip Scale Package, or CSP, Wafer Level Package, or WLP, filters, duplexers, multiplexers, with multiple sizes and multiple packaging substrates, each requiring a new design, requires an increase in design capacity, or improved design efficiency. ~~ISN®~~WaveX™ improves the design efficiency by accurately modeling the performance of acoustic wave filters.

The growing number of filters is also increasing the total size of the RF front-end. In some cases, size constraints require the OEM to fragment its product offering into multiple versions, each with a limited set of filters customized for a particular geographic region. Multiple versions of a mobile product increases manufacturing, inventory and distribution costs. In addition, consumers can find it difficult to roam between carriers and/or countries due to this splintering of bands and phone models. Phone OEMs would prefer to make one version of a product containing a full set of filters that can be electronically selected as required for a particular carrier network.

In addition, the higher frequency 4G bands tend to use relatively expensive BAW technology. Phone OEMs would prefer to use SAW manufacturing processes because of its lower cost and smaller size. However, conventional filter designs using SAW technology do not perform adequately in high frequency bands or in bands with closely spaced receive and transmit channels, typical of many new bands. With the introduction of 5G, which uses even higher frequencies and wider bandwidths, this problem is further exacerbated.

Adding to the complexity of the industry, mobile devices must now be capable of receiving from two, to as many as five, downlink bands simultaneously, known as downlink CA. This CA requirement creates the need for complex multiplexing filters, or multiplexers, which are significantly more complex than duplexers and effectively require four filters for each CA combination. In addition, during the transition to 5G, dual connectivity to both 4G LTE and 5G New Radio (NR) networks is required. 3rd Generation Partnership Project has identified over 400 worldwide band combinations, creating increased complexity and cost to RFFEs. In the case of a quadplexer, with four different frequency bands, within each band the signal loss must be minimized, while rejecting three bands often in close proximity. Duplexers must only reject a single band. Mobile Experts predicts that more than 2 billion terminals will be shipped supporting CA in 2024. This rising complexity in the industry is also aggravating the constraints on design capacity and resources.

In addition to the challenges described above, 5G will further exacerbate the problems of more demand for filters, filter designs, and more complexity and integration in the RFFE. 5G comprises three distinct segments:

•Enhanced mobile broadband (eMBB): Increased bandwidth for extreme data-rates and capacity to support wireless video everywhere;

•~~Mission~~Ultra ~~critical~~Reliable ~~services~~Low Latency Communications (URLLC): High reliability, low latency and high security for automotive, health and government; and

•Massive ~~Internet-of-Things~~Machine Type Communications (mMTC): Low cost, low energy, long life for wearables, smart home devices and interconnected devices.

All three of these segments require filters and will further accelerate the already substantial growth in the filter market.

Our Technology

RFFE module companies currently produce filters internally or purchase filters from third-party manufacturers, such as Broadcom, Murata, Taiyo-Yuden and ~~RF360~~Qualcomm. These module companies and filter manufacturers design filters using their ~~own~~

Table of Contents

own internal resources, which we believe are proving insufficient to meet the explosive growth in both total global filter demand and unique filter designs, as well as the increasingly complex filter requirements necessitated in part by crowded spectrum and carrier aggregation. We believe that our patented ~~ISN®~~WaveX™ technology will enable us to design complex filter products with shortened design times and help our customers benefit from the use of more cost-effective manufacturing processes. ~~ISN®~~WaveX™ can be summarized as a two-step process:

We use circuit models to optimize initial designs. Most of the filter industry models acoustic wave filters using a coupling-of-modes, or COM, model. In contrast, we use circuit models derived from the actual physics of acoustic wave filters. Circuit models are computationally much faster, which allows for very quick optimization of the many possible solutions that result from the synthesis process. We can quickly compare large numbers of different, optimized solutions before commencing the third step - lengthy but highly accurate simulations based on fundamental methods.

We use fundamental models to simulate final designs. Our highly accurate models are based entirely on fundamental material properties and dimensions, again unlike the common practice in the industry today. The precision and accuracy of our models allows for far fewer turns through the fab to reach the desired product performance. Because our models are fundamental, integration with our foundry and fab customers is eased due to the understanding of the basic material properties and dimensions of the fab.

Using our ~~ISN®~~WaveX™ design platform, in 2018 we invented a new resonator technology, XBAR®, with fundamental properties matching the new wireless requirements of higher frequency, wider bandwidth and higher power operation, when compared to previous wireless generations. At Mobile World Congress in 2019 we demonstrated a 5G (n79) filter prototype with the required bandwidth to support 5G operation across the entire band. XBAR® technology is applicable to many current and projected wireless technologies which operate above 3GHz. Hence we are developing designs for both mobile and non-mobile applications for 5G and WiFi, and fully expect to extend this to UWB and 6G. In addition to the fundamental advantages of XBAR®, the straightforward processing for this BAW resonator, lends itself to low cost manufacturing.

Our Commercialization Plan

We will continue to pursue filter design projects with existing and potential customers and other strategic partners, and we believe licensing our designs is the most direct and effective means of delivering our solutions to the market and validating the technical advantages of our tools, IP and team. In addition, we will continue to help develop a fabless filter eco-system to support the growth in the filter volumes for our customers. We will continue to develop XBAR® technology for both mobile and non-mobile applications, including 5G, WiFi and Ultra-WideBand (UWB) applications, forming strategic partnerships with filter manufacturers and customers to bring the technology to market as quickly as possible. We intend to retain ownership of our technology, designs and related improvements and charge royalties based on sales of filters that incorporate our designs. We do not intend to manufacture or sell any physical products or operate as a contract design company developing designs for a fee. Our strategy is to establish and leverage alliances with customers, who will help grow the market for our designs by integrating them with their own proprietary technology and products, thus combining their own particular strengths with ours to provide an extensive array of solutions and to develop and license filter designs that offer improvements in the time to develop, cost, size and performance of RFFEs. The goal for our designs is to improve profit margins and increase market share for our customers.

Our customers are filter manufacturers, RFFE module manufacturers, RF active and passive component suppliers and potentially mobile handset OEMs. Currently, for most of our customers, we license specific, custom designs. In the fourth quarter of 2018 we introduced and announced the first customer for our standard IP filter library of products. In these cases we develop a standard design at one of our qualified foundries and customers can then license this design without paying for or waiting for completion of development, hence minimizing their cost and reducing time to market. We charge royalties at a fixed amount per filter or as a percentage of sales price. In October 2019, we announced a commercial agreement with the industry's largest provider of filters for the RFFE to develop and license filters based on XBAR® technology. In this case, we determined the total amount of royalties expected to result from the licenses being designed and discounted the rate in exchange for prepayment of the amount in advance. The customer agreed to pay up to an aggregate of $9.0 million for the licensed designs and certain other intellectual property developed in the collaboration, payable in installments over a multi-year development period, with each installment conditional upon our achievement of certain milestones and deliverables acceptable to our customer in its discretion. During 2021 the customer entered into an addendum to the collaboration agreement which added up to four additional bands over a multi-year period, the first of which was added during the year. The addendum required an upfront non-refundable payment of $4.0 million and an aggregate of between $8.0 million and $36.0 million, depending on the complexity of the selected bands. The additional band selected during 2021 required an upfront non-refundable fee of $3.0 million and milestone payments totaling $3.0 million due upon the occurrence of certain future events. We expect to generate substantially all of our near-term revenues with these types of licensing arrangements. Each filter design and related royalty stream is expected to have a finite commercial life as mobile devices continue to evolve. Our plan is to offer our customers ~~replacement designs as existing designs become obsolete. Revenue from our contracts may be recognized over time or at a point-in-time depending on the facts and circumstances of each contract.~~

Our products will be designed for manufacture with existing high-volume fabrication processes allowing rapid time to market, but we do not plan to manufacture or sell any physical components. Unlike a manufacturing company, we intend to create designs for manufacturers, eliminating for us the costs and problems associated with manufacturing and inventory. This allows us to concentrate on our unique expertise, leaving the hardware manufacturers to drive their own economies of scale.

We also believe that the power of Resonant WaveX™ tools and methodology will continue to enable fabless customers and filter foundries to newly enter or expand their participation in the supply chain for RF filters. In late 2016, we expanded our customer focus to include fabless filter manufacturers, which are companies that do not have their own internal filter fabrication facility. Typically, these companies already are supplying other products in the RFFE to the OEM, and as a result, do not require a protracted new vendor qualification process in order to supply parts. In 2017, to further facilitate our fabless filter program and to provide manufacturing stability across the supply chain to our fully integrated filter customers, we created our Foundry Program. It is through this program that we can enable a secure supply chain for all our customers. In 2019, we began development of Filter IP Standard Library designs to enable faster time to market for our customers.

Single Band Designs

We continue to develop a series of SAW filter designs for RF frequency bands presently dominated by the larger and more expensive BAW filters. In 2020, we continued to develop single band, SAW filter designs for customers. Some of these filter designs are for duplexers that have historically been TC-SAWs or BAWs while others are for discrete SAW filters that may need improvements in performance, size or cost. The single band designs included WiFi Co-Existence filters, which pass licensed wireless frequencies, while protecting against WiFi ~~from~~ interference, and designs for module applications which require wafer-level packaging (WLP) and modeling of the module board. We believe that, using our ~~ISN®~~WaveX™ technology, combined with our experience and know-how, we can design innovative SAW filters that meet the performance requirements for many of these bands but at significantly less cost than that of BAW filters they would replace. These single band filter designs were the earliest opportunity for royalty revenues~~, and represented the nominal royalty revenues in 2018~~. ~~Since 2018, we have continued to develop single band designs using TC-SAW processes in order to take advantage of the improved temperature stability.~~

Multiplexer Designs

Wireless carriers worldwide are experiencing increasing demand for higher data speeds. CA allows multiple data streams from different frequencies to be added together to provide increased data rate for the mobile users. However, CA further complicates the required filter characteristics. Quadplexers, (4-RF path multiplexer) as described above, enable CA on both receive and transmit paths and reduce the RFFE complexity by reducing the number of switches, but the complexity of the filters themselves increases dramatically. During 2018, we expanded our capability to optimize the performance of quadplexers on OEM phone-boards in order to help our customers demonstrate "real world" performance. During 2019, we expanded our capability to produce TC-SAW and high power quadplexer designs. We believe that our ~~ISN®~~WaveX™ ~~technology~~design platform is ideally suited to these difficult filter design problems that cover a wide frequency range with much more demanding performance requirements.

Although some band combinations for aggregation will not require multiplexers, we believe that multiplexers are the best solution for bands in close frequency proximity. We are developing high performance multiplexer designs to address this growing market.

XBAR® Filters

Our ~~ISN®~~WaveX™ ~~technology~~design platform enabled us to invent a new resonator technology, XBAR®. Large instantaneous bandwidth filters at high frequency (above 3GHz) are required for next generation wireless technologies, such as 5G, WiFi 6E and UWB, to support high data-rates. Filters using XBAR® resonators are ideally suited for these applications. During ~~2020~~2021, we continued to develop XBAR® filter designs for our partner, focused on the mobile market. In addition, we designed and had fabricated through our foundries XBAR® designs for 5G and WiFi non-mobile applications

Our immediate focus is to address the problems in the RFFE with innovative single-band and multiplex designs made possible with our ~~ISN®~~WaveX™ ~~technology~~design platform. These designs present the greatest near-term potential for commercialization of our technology. We expect the trend towards spectrum proliferation, particularly with new 5G spectrum, in addition to CA and MIMO, will require complex filters and multiplexing. We believe our ~~ISN®~~WaveX™ and XBAR® technology will enable cost effective designs for these applications.

We also believe that the power of Resonant ISN® tools and methodology will continue to enable fabless customers and filter foundries to newly enter or expand their participation in the supply chain for RF filters. In late 2016, we expanded our customer focus to include fabless filter manufacturers, which are companies that do not have their own internal filter fabrication facility. Typically, these companies already are supplying other products in the RFFE to the OEM, and as a result, do not require a protracted new vendor qualification process in order to supply parts. In 2017, to further facilitate our fabless filter program and to provide manufacturing stability across the supply chain to our fully integrated filter customers, we created our Foundry Program. Foundries joining the Foundry Program first complete a foundry evaluation process to ensure alignment with our customers for filter performance, manufacturing quality and capacity, and business practices. Once the evaluation is completed, the foundry runs a characterization lot, used to create a foundry process design kit, after which we are ready to start designs for manufacture in the foundry. Packaging/Back-end vendors also can join the program by completing a back-end evaluation process to match their capabilities with foundry partners and our customers. It is through this program that we can enable a secure supply chain for all our customers.10

Intellectual Property

We have an active program protecting our proprietary technology. In protecting our technology, we make use of patent ~~protection~~, trade secret ~~protection~~, trademark ~~protection~~ and mask works ~~protection~~protections. To maximize these protections, we maintain active intellectual property development and protection programs, including with respect to patents, trade secrets, trademarks and mask works.

Our patent portfolio ~~reflects~~is ~~both~~ the ~~initial technology originated at and contributed to us by Superconductor Technologies Inc., or STI, as well as our own patent filings since our founding, and continues to be the~~ result of an active and ongoing program to identify, protect and commercialize our intellectual property. This program includes the development of a comprehensive patent strategy. We engage in a thorough process of patent landscaping that provides an in-depth analysis of not only the markets we are addressing, but also adjacent markets, so that we can tactically and strategically protect our position in the market through patent filings. We also routinely use specialized outside firms to assist in these endeavors. These firms assist with invention identification, intellectual property strategy and competitive landscape analysis. Through our landscaping and advanced product development processes we have plans to file additional patents in ~~2021~~2022.

Our patent portfolio comprises more than ~~300~~415 issued and pending U.S. and foreign patents, with more than ~~150~~265 targeting 5GXBAR. This patent portfolio relates primarily to the following subject matters:

•Physical Implementation

•Design Synthesis and Optimization Speed

•Network Synthesis

We have a formal trade secret program to identify and protect technologies and know-how that derive significant economic value from being secret. This program is managed to provide the optimal levels of protection and competitive advantage to us. We protect our trade secrets and other proprietary information by maintaining the secrecy of such information, including by requiring confidentiality agreements from all our employees, consultants and third parties having access to such information. We have a number of trade secrets already protected in this program and we expect to add more such trade secrets into the program in ~~2021~~2022.

We have also registered U.S. trademarks for ‘‘Resonant®’’, ‘‘~~ISN®~~WaveX™”, ~~“Infinite~~and ~~Synthesized Networks®’’,~~ “XBAR®” ~~and “PMTx®’’~~.

There can be no assurance that our pending patent applications or any future patent applications will be approved or will not be challenged successfully by third parties, that any issued patents will protect our technology or will not be challenged by third parties, or that the patents of others will not have an adverse effect on our ability to do business. Furthermore, there can be no assurance that others will not independently develop similar or competing technology or design around any patents that have been or may be issued to us.

Despite our efforts to maintain the secrecy of our trade secrets, there also can be no assurance that others will not gain access to our trade secrets, or that we can meaningfully protect our technology. Nor can there be assurances that we will succeed in enforcing our trade secrets in the event others improperly gain access to them. In addition, effective trademark, copyright and trade secret protection may be unavailable or limited in certain foreign countries. Although we intend to protect our rights vigorously, there can be no assurance that such measures will be successful.

Competition

To our knowledge, we have no direct competitors in the electronic design automation or licensing business that are exclusively focused on RFFEs. We have spent many years developing ~~ISN®~~WaveX™, and our own patented suite of design tools created specifically for this purpose. No comparable acoustic wave filter design tool exists in the market today to our knowledge. In combination with our experienced design team, we believe we offer our customers a novel solution to the need

Table of Contents

~~combination with our experienced design team, we believe we offer our customers a novel solution to the need~~ for increasingly complex filter designs developed by an independent, stand-alone company that is not presently offered by any other company.

We have advantages that we believe present significant barriers to entry for potential competitors that desire to replicate our business model:

•a large and growing portfolio of patents and trade secrets;

•a suite of proprietary software design tools;

•a growing number of customers;

•a highly experienced design team; and

•a multi-year technology lead.

We do compete with the existing filter designs and design capabilities of the design teams at our customers and target customers and their filter manufacturers. We must demonstrate to our customers, target customers and their filter manufacturers, that switching to our designs will give them a competitive advantage by providing market entry or sufficiently improving the cost, size, and performance of their current products to justify our royalty rates.

The use of our patented ~~ISN®~~WaveX™ tools, not only enables lower cost and smaller size SAW solutions for single band and multiplexer designs but also enables development of creative filter solutions for next generation RFFE architectures that, if successful will offer new, highly competitive solutions to many of the challenges facing the manufacturers of RFFE modules.

Human Capital Resources

We have 6773 employees as of December 31, ~~2020~~2021, 4854 of which are on our technical staff and 19 of which are devoted to finance, sales, marketing and administration matters. We compete for the limited number of highly talented RF filter engineers and work to attract and retain technical talent through offering competitive compensation and benefit packages. We are focused on retaining key contributors, developing our staff, and cultivating their commitment to our Company. We have three primary locations, in California and Texas, where our employees provide services. We also use several outside consultants.

ITEM 1A. RISK FACTORS

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Form 10-K, including our consolidated financial statements and related notes, before investing in our common stock. If any of the following risks materialize, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that event, the price of our common stock could decline, and you could lose part or all of your investment.

Risks Specific to our Company

If our pending acquisition by Murata does not close, our operations after any termination of the Merger Agreement may suffer from the effects of business uncertainties resulting from announcement of the transaction, contractual restrictions on our activities during the period in which we are subject to the Merger Agreement, and costs associated with the proposed transaction.

Uncertainty about the effect of the proposed Offer and Merger on our employees, customers, and other parties may have an adverse effect on our business. Such uncertainty may impair our ability to attract, retain, and motivate key personnel, including our executive leadership, and could cause existing and future customers, suppliers and others to seek to change existing business relationships with us or refuse to do business with us.

The Merger Agreement places limitations on our ability to engage in certain types of transactions without Murata’s consent during the period between the signing of the Merger Agreement and the Effective Time. During this period, we may not raise additional capital through the sale of securities or incur debt. Further, other than in transactions in the ordinary course of business or within specified dollar limits and certain other limited exceptions, we generally may not acquire other businesses, make investments in other persons, or sell, lease, or encumber our assets.

If the Offer and Merger do not close and the Merger Agreement is terminated, we may be unable to raise additional capital to fund our operations for an extended period post-termination.

We have incurred, and will continue to incur, significant costs, expenses, and fees for professional services and other transaction costs in connection with the proposed Offer and Merger. Many of the fees and costs will be payable by us even if the Offer and Merger are not completed.

If our pending acquisition by Murata does not close, the price of our common stock likely will decline.

The Per Share Amount of $4.50 represents approximately a 266% premium to the closing price of our common stock of $1.23 per share on February 14, 2022, immediately prior to announcement of our pending acquisition by Murata, a 227% premium to the 20 trading day volume weighted average stock price of our common stock, and a 157% premium to the 60 trading day volume weighted average stock price of our common stock. If the Offer and Merger do not close and the Merger Agreement is terminated, our stock price likely will decline to or below the prices in effect prior to announcement of our pending acquisition.

Following announcement of the Merger Agreement and commencement of the Offer, numerous lawsuits have been filed against us and members of our Board of Directors, which could delay or prevent consummation of the Offer and the Merger and could have a material adverse effect on our business, results of operations and financial condition.

Numerous lawsuits have been filed against us and members of our Board of Directors and executives, as described in Item 3-Legal Proceedings. These lawsuits seek, among other things, an order enjoining consummation of the Offer and the Merger, rescission of such transactions if they have already been consummated or rescissory damages, and awards of attorneys’ and experts’ fees. These lawsuits may divert financial and management resources that would otherwise be used to benefit our operations. We and our officers and directors believe that the claims asserted in the lawsuits are without merit and intend to vigorously defend our positions. However, a negative outcome in any lawsuit could have a material adverse effect on us if it results in preliminary or permanent injunctive relief or rescission of the transactions contemplated by the Merger Agreement. In addition, although we have directors and officers liability insurance, we anticipate that we will incur significant expense within our self-insured retention under that insurance. We are not currently able to predict the outcome of any of the lawsuits with any certainty. Additional lawsuits arising out of or relating to the transactions contemplated by the Merger Agreement may be filed in the future.

We may require additional capital to continue operations in the future, which capital may not be available on terms acceptable to us, if at all.

As of December 31, 2020, our accumulated deficit totaled $150.9 million. During 2020 our net loss totaled $28.4 million and we used $23.2 million of cash and investments for operating activities, the purchase of property and equipment and expenditures for patents. To date we have not generated significant revenues to enable profitability. We expect to continue to incur significant losses. These factors raise substantial doubt regarding our ability to continue as a going concern. At December 31, 2020 we had cash and cash equivalents of $25.0 million. Subsequent to December 31, 2020, but prior to publication of the financial statements included in this Form 10-K, we raised $4.1 million of cash from sales of common stock using our At-The-Market Equity Offering Sales Agreement. In the absence of a significant revenue increase we project these cash resources will provide sufficient funding into the first quarter of 2022. We are subject to the risks and uncertainties associated with a new business. Our continuance as a going concern is dependent on future profitability. We are actively pursuing expanding our technology portfolio, increasing our revenue opportunities by completing deliverables under current customer contracts and entering into new customer contracts, and efficiently managing operations and exploring cost saving opportunities. We may not be successful in these efforts. We may need to seek to raise additional capital from the sale of equity securities or incurrence of indebtedness. There can be no assurance that additional financing will be available to us on acceptable terms, or at all in which case we might be forced to make substantial reductions in our operating expenses which could adversely affect our ability to implement our business plan and ultimately our viability as a company. Even if available, such capital may be dilutive to existing stockholders. Our consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.13

As of December 31, 2021, our accumulated deficit totaled $186.9 million. During 2021 our net loss totaled $36.0 million and we used $22.1 million of cash and investments for operating activities, the purchase of property and equipment and expenditures for patents. To date we have not generated significant revenues to enable profitability. We expect to continue to incur significant losses. These factors raise substantial doubt regarding our ability to continue as a going concern. At December 31, 2021 we had cash and cash equivalents of $21.2 million. In the absence of additional customer contracts, we believe these cash resources, along with anticipated cash generated from existing customer contracts, will provide sufficient funding into the third quarter of 2022. We are subject to the risks and uncertainties associated with a new business. Our continuance as a going concern is dependent on future profitability. We are actively pursuing expanding our technology portfolio, increasing our revenue opportunities by completing deliverables under current customer contracts and entering into new customer contracts, and efficiently managing operations and exploring cost saving opportunities. We may not be successful in these efforts. We may need to seek to raise additional capital from the sale of equity securities or incurrence of indebtedness.

The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

We have a history of operating losses and we may never achieve or maintain profitability or positive cash flows.

We have a limited operating history and utilize planned milestones for investors to evaluate our progress. We have generated minimal revenues and we have a history of losses from operations with an accumulated deficit as of December 31, ~~2020~~2021 of $~~150~~186.9 million. Our operations have been funded primarily with initial capital contributions, proceeds from the sale of equity securities and debt. We intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to refine existing technology, develop new technology, improve our operating infrastructure or acquire complementary businesses and technologies. Our ability to generate revenues and achieve profitability and, ultimately, positive cash flows, may depend on whether we can obtain additional capital when we need it and will depend on whether we continue to refine our technology and find additional customers who will license our designs. There can be no assurance that we will ever generate meaningful revenues, or that the revenues we do generate will be sufficient to achieve profitability and positive cash flows.

Our business model is based on licensing filter designs, which is unproven. Historically, our target customers have relied on their own filter designs or purchased finished filters from a manufacturer, and have not licensed third-party designs. Consequently, we may not succeed in our licensing strategy, which would require us to adopt a new business model and would have a material adverse effect on our ability to generate revenues and potentially threaten our viability.

Our business model is based on licensing our proprietary filter designs. We do not intend to manufacture or sell any physical products or operate as a contract design company developing designs for a fee. We believe licensing our designs is the most direct and effective means of delivering our solutions to the market. We intend to retain ownership of our designs and charge royalties based on sales of filters and RFFE modules that incorporate our designs.

Our target customers either make part or all of the RFFE. These customers have historically used their own filter designs or purchased finished filters from a manufacturer. Our business model is new to the filter industry and remains unproven, as we have yet to receive meaningful royalty payments from our licensed designs. The failure to scale our business model would have a material adverse effect on our ability to generate revenues and potentially threaten our viability.

We may not be able to complete some of our designs because they do not meet our customers' expectations. Even if we succeed in developing a design that meets all of a customer's requirements, the customer could decline to use our design in their products. Further, our customer's product could fail in the marketplace. Any of these events would have a material adverse effect on our business and potentially threaten our viability.

We develop filter designs to meet our customers' stringent performance specifications. Our customers often ship pre-production samples of our designed filters to their customers for further evaluation. For some designs, mass production may commence. However, the filter qualification process is demanding and some designs will not result in volume production. If successfully developed and selected by our customer, our designs will compete against other technologies for inclusion in our customers’ products. Our customers’ final products will then compete against other products and technologies for inclusion in mobile devices in the marketplace. There can be no assurance that we can complete our designs, that our final designs will have acceptable performance and meet our customers’ specifications, or if our pre-production sample filter shipments will be selected for production. Even if our filter designs have acceptable performance, there are a number of other considerations influencing the customer’s decision whether to use our design, such as packaging type and manufacturing cost, many of which are beyond our control. The decision to use our designs is solely within our customers’ discretion. Further, if our filter design is selected by a customer for inclusion in its design or product, there is no guarantee that the customer’s design or product will be selected for inclusion in mobile devices or, even if selected, result in high-volume sales and meaningful revenues. The failure of a significant number of our designs to be selected at the design stage or the device stage would have a material adverse effect on our business and potentially threaten our viability.

We are not a filter manufacturer, and thus we are reliant on filter fabricators or manufacturers to manufacture filters from our designs. For some of our customers that will not themselves manufacture filters from our designs, we may be required to have our customer approve the filter manufacturer, and the customer will not license our design unless the manufacturer can demonstrate the ability to economically produce the filter in large volumes.

We are a filter design company and will not commercially manufacture any products. Our business model is to license our designs to customers, who will manufacture our designs themselves or rely on third party manufacturers, commonly referred to as foundries, to fabricate our designs for integration into the customer's overall product. We are dependent on foundries’ filter fabrication processes and capabilities for our filter designs. Even with a fully compliant filter design, the customer may not license our design unless the manufacturer can demonstrate the ability to economically produce the design in large volumes. We do not have any control over the manufacturer and cannot provide assurances that the manufacturer will have the necessary technology, skills and resources to successfully manufacture filters from our designs in commercial quantities. Additionally, foundries may refuse to manufacture filters from our designs. Many foundries offer potentially competitive filter technology as part of their standard product line or offer the services of in-house design teams which may consider us competition. In this case, our customers may face resistance by their foundries to manufacture our designs. The reluctance of foundries to manufacture our designs could adversely affect the market acceptance of our designs.

Our designs are complex, may contain latent defects, and may prove difficult to manufacture in commercial quantities. We will be relying on our customers and filter fabricators or manufacturers to build filters from our designs. Our business could fail if they encounter difficulties manufacturing filters in commercial quantities.

We develop complex filter designs, which is inherently challenging. Only a small number of our designed filters are currently in production, and therefore we cannot be certain our methods and testing procedures are adequate to detect latent design defects. If any of our designs contain latent defects, we may be unable to correct these problems. Additionally, we rely on our customers and filter fabricators or manufacturers to manufacture our designed filters. They will need to manufacture filters in commercial quantities at an acceptable cost, and we have little or no control over the manufacturing process. They must also operate and maintain sophisticated manufacturing equipment, and equipment failures can have adverse consequences on production volumes, yields and schedules. They may encounter difficulties in scaling up production, including problems with quality control, raw material and component supply shortages, low manufacturing yields, increased costs, shortages of qualified personnel and/or difficulties associated with compliance with regulatory requirements. Any of these problems may adversely affect the timing and amount of our future revenues. Additionally, if our customers and their suppliers encounter difficulties manufacturing filters from our designs in commercial quantities, our business could fail.

We develop and test our designs under laboratory conditions using low volume production samples. Once in production, our designs may not perform as well, or prove unreliable, due to manufacturing variations and operating conditions. This could adversely affect our business.

We develop and test our designs under laboratory conditions using low volume production samples. The transition from product development to commercial production requires high volume manufacturing which introduces product variations. These variations can adversely affect performance and reliability. Similarly, our designs may not perform as well or prove sufficiently reliable under actual operating conditions. This could adversely affect our business.

Failures in the products or services of our customers, including those resulting from defects or errors, could result in decreased sales and harm our business.

Failures in the products or services of our customers, including those resulting from defects or errors, could result in decreased sales and harm our business.

Our success depends in large part on the demand for mobile wireless devices and other products that incorporate our proprietary filter designs. Our customers’ products are inherently complex and may contain defects or errors unrelated to our designs that are detected only when the products are in use. Any defects or errors in the products of our customers could result in product recalls or the discontinuation of those products, which could have an adverse impact on our operating results due to a delay or decrease in demand for our designs. Further, security failures, defects or errors in mobile wireless devices, such as the issues with the Galaxy Note 7 in 2016 that caused Samsung to discontinue that product, have led to increased scrutiny of component suppliers. If our customers do not perceive our designs to be of high quality, or if mobile device manufacturers do not perceive the products of our customers to be of high quality, or if we or our customers are unable or unwilling to comply with heightened quality assurance requirements of mobile device manufacturers, we may be unsuccessful in having our designed filters incorporated into finished products. In certain instances we perform failure analysis and reliability testing of our customers’ parts. If our analysis and testing prove to be faulty or insufficient, including due to failure of our laboratory equipment or human error, and our customers rely upon the results we provide, our reputation may be damaged, and customers may be reluctant to utilize our services or license our designs. This could harm our ability to attract customers and negatively impact our financial results, and may result in claims against us by our customers or others.

We have completed and continue to actively work on filter designs with, and expect to derive all of our revenues from, a small number of customers. Our failure to retain or expand customer relationships will have an adverse effect on our revenues.

We expect to derive our revenues from a small number of customers. Our failure to retain or expand customer relationships, or any problems we experience in collecting receivables from them, would harm our financial condition and results of operations. Additionally, our industry is experiencing consolidation among suppliers and manufacturers of RF front-end components and modules, including activities of module suppliers who vertically integrate by acquiring component suppliers and fabs. This may lead to fewer customers, reduced demand for our designs and replacement of our designed products by the consolidated company. Any of these possibilities could adversely affect our business, financial condition and results of operations.

We are a solutions company, providing designs based on our ~~ISN®~~WaveX™ software platform, intellectual property and design team. We license our designs to manufacturers of RFFEs, RFFE sub-systems and components for mobile devices. If our designs do not achieve widespread market acceptance among RFFE manufacturers, we will not be able to generate the revenue necessary to support our business.

Achieving additional acceptance among RFFE manufacturers of our designs will be crucial to our continued success. We have a limited history of marketing designs and we may fail to generate significant interest in our designs. These and other factors may affect the rate and level of market acceptance, including our royalty fees and the cost of our designed filters relative to other competing designs and technologies, perception by RF front-end manufacturers and mobile device manufacturers, press and blog coverage, social media coverage and other publicity and public relations factors which are not within our control and regulatory developments related to manufacturing, marketing and selling our designs. If we are unable to achieve or maintain market acceptance, our business would be harmed.

Our designs may not gain widespread acceptance unless they offer greater benefits to our customers than offered by competing RF filter designs.

RF front-end manufacturers are primarily concerned with the cost, size and performance of RF filters. Our designs may not gain widespread acceptance unless, as compared to competing RF filter designs, they are smaller in size, can be fabricated at reduced cost or designed in less time, or improve performance. There can be no assurance that our SAW or TC-SAW filter designs will cost sufficiently less to manufacture than existing BAW filters, or can be designed in less time, to prove economically attractive to RF front-end manufacturers or that our filter designs will be smaller in size or perform better.

Our development cycles are long and our final designs may no longer remain competitive upon completion.

We operate in an industry which is subject to rapidly evolving technologies. Because our designs are expected to have long development cycles, we must anticipate changes in the marketplace and the direction of technological innovation and customer demands. To compete successfully, we will need to demonstrate the advantages of our designs and technologies.

Our intellectual property rights may not be adequate to protect our business

Our success depends significantly on our ability to obtain, maintain and protect our proprietary rights to the technologies used in products incorporating our technologies. We currently hold patents related to various elements of our technology and we also have patent applications currently pending before the United States Patent and Trademark Office and other patent offices around the world. No assurances can be given that any patent will be issued on our pending patent applications or any other application that we may file in the future or that, if such patents are issued, they will be sufficiently broad to adequately protect our technology. In addition, we cannot assure you that any patents that may be issued to us will not be challenged, invalidated, or circumvented.

Additionally, as we continue to expand our business in China, the application and interpretation of China’s intellectual

property right laws and the procedures and standards for granting trademarks, patents, copyrights, know-how or other

Table of Contents

intellectual property rights in China will become more important to our business. Historically, China’s protection of intellectual

property rights has been less stringent and robust compared to other countries such as the United States, and consequently

intellectual property rights and confidentiality protections in China may not be as effective as in the United States or other

countries. Monitoring and preventing unauthorized use is also difficult and the measures we take to protect our intellectual

property rights may not be adequate. Accordingly, infringement of our intellectual property rights poses a serious risk of doing

business in China.

If we are unable to protect the confidentiality of our proprietary information and know-how, the value of our technology, products and services could be harmed significantly.

In addition to seeking patents for some of our technologies, we also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. We seek to protect these trade secrets, in part, by entering into non-disclosure and confidentiality agreements with parties who have access to them, such as our employees, consultants, collaborators, advisors, independent contractors and other third parties. We also enter into confidentiality, non-competition, non-solicitation, and invention assignment agreements with our employees and consultants that obligate them to assign to us any inventions developed in the course of their work for us. However, we cannot guarantee that we have executed these agreements with each party that may have or have had access to our trade secrets or that the agreements we have executed will provide adequate protection. Additionally, we also seek to preserve the integrity and confidentiality of our technologies and trade secrets by maintaining physical and electronic security of our premises and information technology systems. While we have confidence in these individuals, organizations and systems, agreements or security measures may be breached, and we may not have adequate remedies for such breaches. Furthermore, competitors may otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. As a result, we may be forced to bring claims against third parties, or defend claims that they bring against us, to determine ownership of what we regard as our intellectual property. Monitoring unauthorized disclosure is difficult and we do not know whether the procedures that we have followed to prevent such disclosure are or will be adequate. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States may be less willing or unwilling to protect trade secrets. If any of the technology or information that we protect as trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to, or independently developed by, a competitor, our competitive position would be harmed.

Our proprietary rights may be difficult to enforce, which could enable others to copy or use aspects of our intellectual property without compensating us, thereby eroding our competitive advantages and harming our business.

Our success depends, in part, on our ability to protect proprietary methods and technologies that we develop under the intellectual property laws of the United States, so that we can prevent others from using our inventions and proprietary information. If we fail to protect our intellectual property rights adequately, our competitors might gain access to our technology, and our business might be adversely affected. We rely on trademark, copyright, mask works, trade secret and patent laws, confidentiality procedures and contractual provisions to protect our proprietary methods and technologies. We currently hold patents and have pending patent applications related to our technology solutions. Valid patents may not be issued from our pending applications, and the claims allowed on any issued patents may not be sufficiently broad to protect our technology or offerings and services. Any patents we currently hold or that may be issued to us in the future may be challenged, invalidated or circumvented, and any rights granted under these patents may not actually provide us with adequate defensive protection or competitive advantages. Additionally, the process of obtaining patent protection is expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.

Policing unauthorized use of our technology is difficult. Additional uncertainty may result from changes to intellectual property legislation enacted in the United States, including the America Invents Act, and other countries and from interpretations of the intellectual property laws of the United States and other countries by applicable courts and agencies. In addition, the laws of some foreign countries may not be as protective of intellectual property rights as those of the United States, and mechanisms for enforcement of our proprietary rights in such countries may be inadequate. From time to time, legal action by us may be necessary to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement. Such litigation could result in substantial costs and the diversion of limited resources and could negatively affect our business, operating results and financial condition. If we are unable to protect our proprietary rights (including aspects of our technology platform) we may find ourselves at a competitive disadvantage to others who have not incurred the same level of expense, time and effort to create and protect their intellectual property.

Table of Contents

Furthermore, we acquired some of the patents we currently hold from Superconductor Technologies, Inc., or STI. Although we believe we have obtained valid assignments of patent rights from STI and STI has obtained valid assignments of patent rights from all inventors, if an inventor did not adequately assign his or her patent right to STI or STI did not adequately assign its patent rights to us, a third party could obtain a license to the patent from such inventor or STI. This could preclude us from enforcing the patent against such third party. In addition, because we acquired our patents from STI, some of the inventors of our patents are not our employees and they are not obligated to assist us in prosecuting, maintaining, defending and enforcing such patents. Without the cooperation of the inventors of our patents, it may be difficult for us to prevail in any legal action involving the intellectual property rights under our patents. Additionally, the inventors may have information, trade secrets and know-how learned while at STI that is not our property and if disclosed could provide competitors with insights that allow them to invent around our patented technology.

Accordingly, despite our efforts, we may be unable to obtain adequate patent protection, or to prevent third parties from infringing upon, misappropriating or inventing around our intellectual property.

We may be subject to intellectual property rights claims by third parties, which are extremely costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies.

Third parties may assert claims of infringement of intellectual property rights in proprietary technology against us for which we may be liable or have an indemnification obligation. Any claim of infringement by a third party, even those without merit, could cause us to incur substantial costs defending against the claim and could distract our management from our business.

Although third parties may offer a license to their technology, the terms of any offered license may not be acceptable and the failure to obtain a license or the costs associated with any license could cause our business, results of operations or financial condition to be materially and adversely affected. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. Alternatively, we may be required to develop non-infringing technology, which could require significant effort and expense and ultimately may not be successful. Furthermore, a successful claimant could secure a judgment or we may agree to a settlement that prevents us from licensing certain designs or performing certain services or that requires us to pay substantial damages, including treble damages if we are found to have willfully infringed the claimant’s patents or copyrights, royalties or other fees. Any of these events could seriously harm our business, operating results and financial condition.

We may be unsuccessful in monetizing our intellectual property portfolio.

We have dedicated substantial resources to the development and protection of technology innovations essential to our business, and we expect these activities to continue for the foreseeable future. We also intend to aggressively pursue monetization avenues for our intellectual property portfolio, potentially including licensing, royalty or other revenue-producing arrangements. However, our revenues are currently generated in part by licensing our technology and we may never be successful in generating a revenue stream from our intellectual property, in which case our investments of time, capital and other resources into our intellectual property portfolio may not provide adequate, or any, returns.

Our customer agreements include indemnity provisions and may expose us to substantial liability for intellectual property infringement and other losses.

Our customer agreements include indemnification provisions under which we agree to indemnify third parties for losses suffered or incurred as a result of claims of intellectual property infringement, damages caused by us to property or persons, or other liabilities relating to or arising from our designs, services, or other contractual obligations. The term of these indemnity provisions generally survives termination or expiration of the applicable agreement. Large indemnity payments could harm our business, operating results and financial condition.

We use highly specialized proprietary software as well as commercially available software pursuant to annual licenses, and the failure of this software or inability to renew any of these licenses could adversely affect our ability to design new RF filters and thus our potential for generating revenues.

We have developed and use highly specialized proprietary computer software in our design process. The failure of any of this software to perform as expected could adversely affect our ability to produce new RF filter designs and thus our potential for generating revenues. In addition to our proprietary software, we also use highly specialized but commercially available computer software in our design process. We do not own this software and use it under the terms of licenses. These licenses are made available to us at prices and on terms generally available to any customer. If we were unable to renew any of these software licenses, we would have to locate or develop alternative software. We cannot assure you that suitable alternative software would be available on commercially reasonable terms or could be developed by us at reasonable cost. The loss of any one of these software licenses could adversely affect our ability to produce new RF filter designs and thus our potential for generating revenues.

Risks Related to Our Industry

Our industry is subject to intense competition and rapid technological change, which may result in designs, products or new solutions that are superior to our designs under development. If we are unable to anticipate or keep pace with changes in the marketplace and the direction of technological innovation and customer demands, our designs may become less useful or obsolete and our operating results will suffer.

We operate in an industry which is subject to intense and increasing competition. Our future success will depend in large part on our ability to establish and maintain a competitive position in current and future technologies. Rapid technological development may render our designs and technologies obsolete. Many of our competitors have or may have greater engineering, sales, marketing, operational, corporate and financial resources, and more experience in research and development than we have. We cannot assure you that our competitors will not succeed in developing or marketing technologies or products that are more effective or commercially attractive than our designs or that would render our technologies and designs obsolete. We may not have or be able to raise or develop the financial resources, technical expertise, or support capabilities to compete successfully in the future. Our success will depend in large part on our ability to maintain a competitive position with our technologies.

The markets in which we compete are cyclical and any future downturn may delay or reduce the demand for our designs and resulting royalty revenue.

Historically, the markets in which we compete have experienced significant downturns, often connected with, or in anticipation of, declines in consumer demand for end-user products, the maturation of product cycles and declining general economic conditions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels, accelerated erosion of average selling prices, bad debt, inventory charges, restructuring charges, and asset impairment charges. Any future downturn in the markets in which we compete, or changes in demand for our designs from our customers, could result in a significant delay in our realization of or reduction in our revenue and may also increase the volatility of the price of our common stock.

If our principal end markets fail to grow or experience declines, our revenue may not meet our business plan expectations.

Our initial designs are being incorporated into mobile wireless devices. Accordingly, demand for our designs is dependent on the ability of mobile wireless device manufacturers to successfully sell wireless devices that incorporate our designs. We cannot be certain whether these manufacturers will be able to create or sustain demand for their wireless devices that contain our designs or how long they will remain competitive in their business, if at all. The success of these mobile wireless device manufacturers and the demand for their wireless devices can be affected by a number of factors, including, but not limited to:

•market acceptance of their mobile wireless devices that contain our designs;

•the impact of slowdowns or declines in sales of mobile wireless devices in general;

•their ability to design products with features that meet the evolving tastes and preferences of consumers;

•fluctuations in foreign currency;

•relationships with wireless carriers in particular markets;

Table of Contents

•the implementation of, or changes to, mobile wireless device certification standards and programs;

•technological advancements in the functionality and capabilities of mobile wireless devices;

•the imposition of restrictions, tariffs, duties, or regulations by foreign governments on mobile wireless device manufacturers;

•failure to comply with governmental restrictions or regulations;

•cost and availability of components for their products; and

•inventory levels in the sales channels into which mobile wireless device manufacturers sell their products.

Security breaches and improper access to or disclosure of our proprietary information, or other hacking attacks on our systems, could adversely affect our business.

Table of Contents

Our industry is prone to cyber-attacks, with third parties seeking unauthorized access to our proprietary information and technology. Computer malware, viruses, and hacking and phishing attacks by third parties have become more prevalent in our industry and may occur on our systems in the future. We believe such attempts are increasing in number and in technical sophistication, and in some instances we may be unable to anticipate these techniques or to implement adequate preventative measures. Additionally, we may be unaware of an incident or its magnitude and effects. Although we have developed systems and processes that are designed to protect our proprietary information and to prevent other cybersecurity breaches, we cannot guarantee that such measures will provide absolute security.

Any failure to prevent or mitigate security breaches and improper access to or disclosure of our proprietary information could result in the loss or misuse of such proprietary information, which could harm our business and diminish our competitive position. Such attacks may also create system disruptions or cause shutdowns. Publicity about vulnerabilities and attempted or successful incursions could damage our reputation with customers and reduce demand for our products and services.

Affected private parties or government authorities could initiate legal or regulatory actions against us in connection with any security breaches, which could cause us to incur significant expense and liability or result in orders or consent decrees forcing us to modify our business practices. Any of these events could have a material and adverse effect on our business, reputation, and operating results.

Risks Related to Government Regulation

Our failure to comply with U.S. laws and regulations relating to the export and import of goods, technology, and software could subject us to penalties and other sanctions and restrict our ability to license and develop our filter designs.

We are obligated by law to comply with all U.S. laws and regulations governing the export and import of goods, technology, and services, including the International Traffic in Arms Regulations, or ITAR, the Export Administration Regulations, or EAR, regulations administered by the Department of Treasury’s Office of Foreign Assets Control, and regulations administered by the Bureau of Alcohol Tobacco Firearms and Explosives governing the importation of items on the U.S. Munitions Import List. Pursuant to these regulations, we are responsible for determining the proper licensing jurisdiction and export classification of our filter designs, and obtaining all necessary licenses or other approvals, if required, for exports and imports of technical data, and software, or for the provision of technical assistance or other defense services to or on behalf of foreign persons. We are also required to obtain export licenses, if required, before employing or otherwise utilizing foreign persons in the performance of our contracts if the foreign person will have access to export-controlled technical data or software. The violation of any of the applicable laws and regulations could subject us to administrative, civil, and criminal penalties.

These regulations could restrict our ability to license existing filter designs and develop new designs. For example, as a result of ITAR requirements, we are unable to supply certain products to China satellite companies or end users, which comprise a significant part of the overall satellite market. Changes in our designs or changes in export and import regulations may create delays in the introduction of our designs in international markets, prevent our customers with international operations from deploying products incorporating our designs throughout their global systems or, in some cases, prevent the export or import of product including our designs to certain countries altogether. Any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons, or technologies targeted by such regulations, could result in decreased use of our designs by, or our ability to export or license our designs to, existing or potential customers with international operations and decreased revenue. For example, in late 2020 the U.S. Bureau of Industry and Security of the U.S. Department of Commerce placed a China-based customer of ours on the Bureau’s Entity List, which resulted in our suspending exports of our technologies to this customer while we seek a limited export license from the U.S. Department of Commerce. Any failure to comply with these laws could result in sanctions by the U.S. government, including substantial monetary penalties, denial of export privileges, and debarment from government contracts.

Changes in China’s economic, political or social conditions or government policies, including rising tensions between China and the United States, could have a material adverse effect on our business and results of operations.

Table of Contents

~~U.S.~~furtherance ~~government~~of China’s stated policy of reducing its dependence on foreign semiconductor manufacturers, ~~including~~could ~~substantial~~increase ~~monetary~~the ~~penalties~~cost of doing business in China, ~~denial~~foster the emergence of ~~export~~Chinese-based ~~privileges~~competitors, ~~and~~decrease ~~debarment~~the ~~from~~demand ~~government~~for ~~contracts~~our customers’ products in China, or reduce the supply of critical materials for our customers’ products, which could have a material adverse effect on our business and results of operations.

Our business, prospects, financial condition and results of operations may be significantly affected by the political, economic and social climate in China, including without limitation the rising tensions in the relationships between China, surrounding Asian countries, and the United States. As a result, our customers may incur increases in costs due to changes in tariffs, import or export restrictions (or other trade barriers), or unexpected changes in regulatory requirements, which could harm our business. Given the relatively fluid regulatory environment in China, there could be additional tax or other regulatory changes in the future. Such actions in the future, as well as other changes in Chinese laws and regulations, including actions in furtherance of China’s stated policy of reducing its dependence on foreign semiconductor manufacturers, could increase the cost of doing business in China, foster the emergence of Chinese-based competitors, decrease the demand for our customers’ products in China, or reduce the supply of critical materials for our customers’ products, which could have a material adverse effect on our business and results of operations.

If we fail to comply with anti-bribery laws, including the U.S. Foreign Corrupt Practices Act, or FCPA, we could be subject to civil and/or criminal penalties.

As a result of our international operations, we may be subject to anti-bribery laws, including the FCPA, which prohibits companies from making improper payments to foreign officials for the purpose of obtaining or keeping business. If we fail to comply with these laws, the U.S. Department of Justice, the SEC, or other U.S. or foreign governmental authorities could seek civil and/or criminal sanctions, including monetary fines and penalties against us or our employees, as well as additional changes to our business practices and compliance programs, which could have a material adverse effect on our business, results of operations, or financial condition.

Developments stemming from changes in Government administrations, both foreign and domestic, including the imposition of tariffs and export restrictions and other changes in government trade policies, could limit our ability to license our designs, which could adversely affect our business.

Changes in Government administration could result in changes to political, regulatory and economic laws, policies and conditions that could severely and negatively impact our business. For example, the Trump administration negotiated a new North American trade pact to replace the North American Free Trade Agreement, withdrew the United States from the Trans-Pacific Partnership (TPP), and has imposed tariffs on goods imported into the United States, including from China, which has imposed retaliatory tariffs affecting certain products manufactured in the United States. Our customers are located around the world, and we expect that international sales will comprise a substantial portion of total sales in the future. In addition, we expect that products utilizing our designs will be produced, assembled and tested at third-party manufacturing facilities located primarily in Asia. Changes in U.S. political, regulatory and economic conditions or laws and policies governing U.S. tax laws, foreign trade, manufacturing, and development and investment in the countries where we or our customers operate could adversely affect our operating results and our business. For example, imposition of tariffs on our customers’ products that are imported from China to the United States could harm sales of such products, which would harm our business. We cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and China or other countries, what products may be subject to such actions, or what actions may be taken by the other countries in retaliation.

Changes in current laws or regulations or the imposition of new laws or regulations could impede the license of our designs or otherwise harm our business.

Wireless networks can only operate in the frequency bands, or spectrum, allowed by regulators and in accordance with rules governing how the spectrum can be used. The Federal Communications Commission, or the FCC, in the United States, as well as regulators in foreign countries, have broad jurisdiction over the allocation of frequency bands for wireless networks. We therefore will rely on the FCC and international regulators to provide sufficient spectrum and usage rules. For example, countries such as China, Japan or Korea heavily regulate all aspects of their wireless communication industries, and may restrict spectrum allocation or usage. If this were to occur elsewhere, it would make it difficult for us to license our designs for use in mobile devices in that region.

Risks Related to Ownership of our Stock

The price of our common stock may be volatile and the value of your investment could decline

Table of Contents

Technology stocks have historically experienced high levels of volatility. The trading price of our common stock may fluctuate substantially, depending on many factors, some of which are beyond our control and may not be related to our operating performance. These fluctuations could cause you to lose all or part of your investment in our common stock. Factors that could cause fluctuations in the trading price of our common stock include, but are not limited to, the following:

•the progress, completion or failure of efforts to design our commercial products;

•a customer decision regarding incorporation of our designs into a commercial product;

•the loss of any customer relationship;

•the addition of a new customer relationship;

•mergers and acquisitions involving us, our customers or our competitors;

•price and volume fluctuations in the overall stock market from time to time;

•significant volatility in the market price and trading volume of technology companies in general;

Table of Contents

•fluctuations in the trading volume of our shares or the size of our public float;

•actual or anticipated changes or fluctuations in our results of operations;

•whether our results of operations meet the expectations of securities analysts or investors;

•actual or anticipated changes in the expectations of investors or securities analysts;

•litigation involving us, our industry, or both;

•regulatory developments in the United States, foreign countries, or both;

•general economic conditions and trends;

•major catastrophic events;

•lockup releases, sales of large blocks of our common stock;

•departures of key employees; or

•an adverse impact on the company from any of the other risks cited herein.

In addition, if the market for technology stocks or the stock market in general, experience a loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, results of operations or financial condition. The trading price of our common stock might also decline in reaction to events that affect other companies in our industry even if these events do not directly affect us. Securities class action litigation has often been instituted against companies following periods of volatility in the overall market and in the market price of a company’s securities. Two putative class action lawsuits were filed in March 2015 against the Company and certain members of the Board of Directors and executives and subsequently settled. We may be the target of securities-related litigation in the future. Such litigation could divert our management’s attention and resources, result in substantial costs, and have an adverse effect on our business, results of operations and financial condition.

If we raise additional capital in the future, your ownership in us could be diluted.

Any issuance of equity we may undertake in the future to raise additional capital could cause the price of our common stock to decline, or require us to issue shares at a price that is lower than that paid by holders of our common stock in the past, which would result in those newly issued shares being dilutive. Any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing that we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, including the ability to pay dividends, which could impair the value of our common stock. This may make it more difficult for us to obtain additional capital and to pursue business opportunities.

Our limited operating history makes it difficult to evaluate our business and prospects and may increase the risks associated with your investment.

We have only a limited operating history upon which our business and future prospects may be evaluated. We have encountered and will continue to encounter risks and difficulties frequently experienced by companies in rapidly developing and changing industries, including challenges related to recruiting, integrating and retaining qualified employees; making effective use of our limited resources; achieving market acceptance of our existing and future solutions; competing against companies with greater financial and technical resources; and developing new solutions. Our current operational infrastructure may require changes for us to scale our business efficiently with additional technical personnel and effectively to keep pace with demand for our solutions, and achieve long-term profitability. If we fail to implement these changes on a timely basis or are unable to implement them effectively, our business may suffer. We cannot assure you that we will be successful in addressing these and other challenges we may face in the future. As a company in a rapidly evolving industry, our business prospects depend in large part on our ability to:

•build a reputation for a superior solution and create trust and long-term relationships with our customers;

Table of Contents

•distinguish ourselves from competitors in our industry;

•develop and offer competitive technologies that meet our customers’ needs as they change;

•respond to evolving industry standards and government regulations that impact our business;

•expand our business internationally; and

•attract, hire, integrate and retain qualified and motivated employees.

If we are unable to meet one or more of these objectives or otherwise adequately address the risks and difficulties that we face, our business may suffer, our revenue may decline and we may not be able to achieve growth or long-term profitability.

Our limited visibility into future demand for products incorporating our finished filter designs makes it difficult to forecast royalty revenue.

Table of Contents

Our customers have had difficulty accurately forecasting their product sales volumes and the timing of new product introductions, which ultimately affects the royalties we expect to receive for sales of products incorporating our finished filter designs. Our limited visibility into the demand for our customers’ products makes it difficult for us to accurately forecast royalty revenues, which we expect will continue for the foreseeable future.

If securities or industry analysts do not publish research or reports about our business, or publish inaccurate or unfavorable research reports about our business, our share price and trading volume could decline.

The trading market for our common stock will, to some extent, depend on the research and reports that securities or industry analysts publish about us or our business. We do not have any control over these analysts. If one or more of the analysts who cover us should downgrade our shares or change their opinion of our business prospects, our share price would likely decline. If one or more of these analysts ceases coverage of our company or fails to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

We do not intend to pay dividends for the foreseeable future and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.

We have never declared or paid any dividends on our common stock. We intend to retain any earnings to finance the operation and expansion of our business, and we do not anticipate paying any cash dividends in the future. As a result, you may only receive a return on your investment in our common stock if the market price of our common stock increases.

Our ability to use our net operating loss carryforwards (“NOLs”) and other tax attributes to offset future taxable income may be limited.

We have significant NOLs and R&D tax credits available to offset our future United States federal and state taxable income. Under Sections 382 and 383 of Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change NOLs and other pre-change tax attributes, such as R&D tax credits, to offset its post-change income and taxes may be limited. In general, an “ownership change” occurs if there is a cumulative change in our ownership by “5% shareholders” that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. In 2014 and 2017 ownership changes, as defined in Section 382 of the Internal Revenue Code, occurred which resulted in annual limitations on our federal net operating loss carryforwards; however, we believe it is more likely than not that none of the federal net operating loss carryforwards will expire as a result of the of limitations under Section 382. If we experience additional ownership changes as a result of future transactions in our stock, then we may be further limited in our ability to use our NOLs and other tax assets to reduce taxes owed on the net taxable income that we earn. Any such limitations on the ability to use our NOLs and other tax assets could adversely impact our business, financial condition and operating results. In addition, California and certain states have suspended use of NOLs for certain taxable years and other states are considering similar measures. As a result, we may incur higher state income tax expense in the future. Depending on our future tax position, continued suspension of our ability to use NOLs in states in which we are subject to income tax could have an adverse impact on our operating results and financial condition.

Our charter documents and Delaware law could discourage takeover attempts and lead to management entrenchment.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent a change in control of our company. These provisions could also make it difficult for stockholders to elect directors that are not nominated by the current members of our board of directors or take other corporate actions, including effecting changes in our management. These provisions include:

Table of Contents

•the ability of our board of directors to issue shares of preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

•the exclusive right of our board of directors to elect a director to fill a vacancy created by the expansion of our board of directors or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

•a prohibition on stockholder action by written consent, which forces stockholder action to be taken at an annual or special meeting of our stockholders;

•the requirement that a special meeting of stockholders may be called only by the chairman of our board of directors, the chief executive officer, the president (in the absence of a chief executive officer) or a majority vote of our board of directors, which could delay the ability of our stockholders to force consideration of a proposal or to take action, including the removal of directors;

•the requirement for the affirmative vote of holders of at least 66-2/3% of the voting power of all of the then-outstanding shares of the voting stock, voting together as a single class, to amend the provisions of our amended and restated certificate of incorporation relating to the management of our business or our amended and restated bylaws, which may inhibit the ability of an acquirer to effect such amendments to facilitate an unsolicited takeover attempt;

•the ability of our board of directors, by majority vote, to amend our amended and restated bylaws, which may allow our board of directors to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend our amended and restated bylaws to facilitate an unsolicited takeover attempt; and

•advance notice procedures with which stockholders must comply to nominate candidates to our board of directors or to propose matters to be acted upon at a stockholders’ meeting, which may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time.

General Risks

The ongoing, global coronavirus pandemic has significantly and adversely affected, and may continue to adversely affect, our business, financial position, results of operations and cash flows.

Further, the pandemic’s ultimate impact~~ depends in part on many factors not within our control and ~~which~~that ~~may~~ vary by region ~~(heightening the uncertainty as to the ultimate impact COVID-19 may have on our operations and financial performance)~~, including, without limitation:, restrictive governmental and business actions that ~~have been and~~ continue to be taken in response (including travel restrictions, ~~work from home requirements,~~ and other workforce limitations); economic stimulus, funding and relief programs and other governmental economic responses; the effectiveness of governmental actions; economic uncertainty in key global markets and financial market volatility; levels of economic contraction or growth; the impact of the pandemic on health and safety; the pace of recovery if and when the pandemic subsides; and how significantly the number of cases increases as economies reopen and restrictive governmental and business actions are relaxed.

However, ~~including~~our ~~those~~ability ~~discussed~~to ~~below:~~interact with customers has been impacted by the current environment. For example, we believe that our inability to meet in-person with current or prospective customers, as well as the cancellation or postponement of Company-sponsored events or third-party events at which our products are featured, may have a negative impact on our business.

•Operations-related risks: Our business is facing increased operational challenges including a heightened need to protect employee health and safety, office shutdowns, workplace disruptions, and restrictions on the movement of people, both at our own offices and at those of our clients and suppliers. We are also experiencing, and expect to continue experiencing, client requests for engagement deferrals and other factors related directly and indirectly to the 23

The full extent of the effect of the pandemic on us, our customers, our supply chain and our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the duration and severity of the outbreak or subsequent outbreaks. We may continue to experience the effects of the pandemic even after it has waned, and our business, results of operations and financial condition could continue to be affected. In particular, if COVID-19 continues to spread or re-emerges, particularly in the United States, Japan and China where our operations are most concentrated, resulting in a prolonged period of travel, commercial, social and other similar restrictions, we could experience, among other things:

•Adverse impacts on our operations and financial results caused by government and regulatory measures to contain or mitigate the spread of the virus, temporary closures of our facilities or the facilities of our customers or suppliers, which could impact our ability to timely meet our customers’ orders or negatively impact our supply chain;

•The failure of third parties on which we rely, including our suppliers, customers and external business partners, to meet their respective obligations to us, or significant disruptions in their ability to do so, which may be caused by their own financial or operational difficulties including bankruptcy or default;

•Disruptions or restrictions on our employees’ ability to work effectively, due to illness, quarantines, travel bans, shelter-in-place orders or other limitations;

•Interruptions to the operations of our business if the health of our executives, management personnel and other employees are affected, particularly if a significant number of individuals are impacted;

•Any accident, COVID-19 illness, or injury to our employees could result in litigation, development delays and harm to our reputation, which could negatively affect our business, results of operations and financial condition;

•Changes in prices of products and services may be impacted by worldwide demand and by the ongoing COVID-19 pandemic, and such price increases could materially increase our operating costs and adversely affect our profit margin;

•Increased cybersecurity and privacy risks and risks related to the reliability of technology to support remote operations;

•Sudden and/or severe declines in the market price of our common stock; and

•Costs incurred and revenues lost during and from the effects of the COVID-19 pandemic likely will not be recoverable.

The COVID-19 pandemic may also affect our operations and financial results in a manner that is not presently known to us or that we currently do not expect to present significant risks to our operations or financial results.

Our worldwide operations are subject to political, legal and economic risks and catastrophic events, such as natural disasters, war, acts of terrorism and epidemics that could disrupt the business of our customers or harm our facilities, which could have a material adverse effect on us.

Our customers are located around the world, including in the United States and Asia, and we expect that international sales will comprise a significant portion of total sales in the future. In addition, products utilizing our designs will be produced, assembled and tested at third-party manufacturing facilities located primarily in Asia. Consequently, we are subject to political, legal and economic risks associated with operations in foreign countries, including, without limitation:

Table of Contents

assembled and tested at third-party manufacturing facilities located primarily in Asia. Consequently, we are subject to political, legal and economic risks associated with operations in foreign countries, including, without limitation:

•expropriation;

•changes in a specific country’s or region’s political or economic conditions;

•changes in tax laws, trade protection measures and import or export licensing requirements;

•difficulties in protecting our intellectual property;

•difficulties in managing staffing and exposure to different employment practices and labor laws;

•changes in foreign currency exchange rates;

•restrictions on transfers of funds and other assets of our subsidiaries between jurisdictions;

•changes in freight and interest rates;

•disruption in air transportation between the United States and overseas facilities;

•loss or modification of exemptions for taxes and tariffs; and

•compliance with U.S. laws and regulations related to international operations, including export control and economic sanctions laws and regulations and the Foreign Corrupt Practices Act.

In addition, our worldwide operations (or those of our business partners) could be subject to natural disasters such as earthquakes, tsunamis, flooding, typhoons and volcanic eruptions, war, acts of terrorism, pandemic events and the spread of disease, all of which are outside of our control and could disrupt manufacturing or other operations. For example, our Goleta and ~~Burlingame~~San Mateo operations are located near major earthquake fault lines in California. Any conflict or uncertainty in the countries in which we operate, including public health issues, safety issues, natural disasters, disruptions of service from utilities, nuclear power plant accidents or general economic or political factors, could have a material adverse effect on our business. Any of the above risks, should they occur, could result in an increase in the cost of components, production delays, general business interruptions, delays from difficulties in obtaining export licenses for certain technology, tariffs and other barriers and restrictions, longer payment cycles, increased taxes, restrictions on the repatriation of funds and the burdens of complying with a variety of foreign laws, any of which could ultimately have a material adverse effect on our business.

Our future revenue is inherently unpredictable. As a result, as our revenues increase our operating results are likely to fluctuate from period to period, and we may fail to meet the expectations of our analysts and investors, which may cause volatility in our stock price and may cause our stock price to decline.

As we generate revenue, we expect our quarterly and annual operating results to fluctuate significantly due to a variety of factors, some of which are outside of our control. Factors that could cause our quarterly or annual operating results to fluctuate include:

•a downturn in the markets for our customers’ products;

Table of Contents

•disruptions or delays in the manufacture of our designed filters, our customers’ products, or the products into which our customers’ products are incorporated, or in the supply of raw materials or product components used to produce such filters or products;

•a failure to anticipate changing customer product requirements;

•market acceptance of our designs;

•cancellations or postponements of previously placed orders for our customers’ products;

•increased financing costs or any inability to obtain necessary financing;

•the impact on our business of any cost reduction measures;

•a loss of key personnel or the shortage of available skilled workers;

•economic conditions in various geographic areas where we or our customers do business;

•the impact of political uncertainties, such as government sequestration and uncertainties surrounding the federal budget, customer spending and demand for products incorporating our designs;

•other conditions affecting the timing of orders of our customers’ products incorporating our designs;

•reductions in the royalty rates for our designs occasioned by a reduction in the prices for our customers’ products, increases in the costs of raw materials used to produce our customers’ products, or other factors;

•effects of competitive pricing pressures, including decreases in average selling prices of RF filters that compete with our filter designs, resulting in reduced royalty revenue;

•obsolescence of our designs;

•research and development expenses incurred with respect to new filter design introductions;

•natural disasters, such as hurricanes, earthquakes, fires, and floods;

•the emergence of new industry standards;

•the loss or gain of significant customers;

•the introduction of new designs and manufacturing processes;

•changes in technology;

Table of Contents

•intellectual property disputes;

•customs (including tariffs imposed on products, or components thereof, into which our filter designs are incorporated, or the equipment used in the production of such products), import/export, and other regulations of the countries in which we do business;

•the occurrence of M&A activities; and

•acts of terrorism or violence and international conflicts or crises, including pandemic events and the spread of disease.

If we choose to acquire new businesses, products or technologies, we may experience difficulty in the identification or integration of any such acquisition, and our business may suffer.

Our commercial success depends on our ability to continually enhance and broaden our product offerings in response to changing customer demands, competitive pressures and technologies. Accordingly, we may in the future pursue the acquisition of complementary businesses, products or technologies instead of developing them ourselves. We do not know if we will be able to identify or complete any future acquisitions, or whether we will be able to successfully integrate any acquired business, product or technology or retain key employees. Integrating any business, product or technology we acquire could be expensive and time consuming, disrupt our ongoing business and distract our management. Moreover, we may fail to realize the anticipated benefits of any acquisition. If we are unable to integrate any acquired businesses, products or technologies effectively, our business will suffer. In addition, any amortization or charges resulting from acquisitions could adversely affect our operating results.

The loss of the services of our key management and personnel or the failure to attract additional key personnel could adversely affect our ability to operate our business.

A loss of one or more of our current officers or key employees could severely and negatively impact our operations. We have no present intention of obtaining key-man life insurance on any of our executive officers or management. Additionally, competition for highly skilled technical, managerial and other personnel is intense. As our business develops, we might not be able to attract, hire, train, retain and motivate the highly skilled managers and employees we need to be successful. If we fail to attract and retain the necessary technical and managerial personnel, our business may not grow, may suffer and might fail.

If our estimates or judgments relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our operating results could fall below the expectations of securities analysts and investors, resulting in a decline in our stock price.25

The preparation of financial statements in conformity with generally accepted accounting principles, or GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in Item 7--Management’s Discussion and Analysis of Financial Condition and Results of Operations, the results of which form the basis for making judgments about the carrying values of assets, liabilities, equity, revenue and expenses that are not readily apparent from other sources. Our operating results may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our operating results to fall below the expectations of securities analysts and investors, resulting in a decline in our stock price. Significant assumptions and estimates used in preparing our consolidated financial statements include those related to the fair values of equity instruments, other financial instruments and income taxes.

Changes in U.S. tax laws and regulations may have a material adverse effect on our business, cash flow, operating results, and financial condition.

Changes in tax laws and regulations, or changes in the interpretation of tax laws and regulations by federal or state authorities, may have a material adverse effect on our business, cash flows, operating results or financial condition. Changes in corporate tax rates and the deductibility of expenses included in future tax reform legislation could have a material impact on the future value of our deferred tax assets, could result in significant one-time costs or expenses in the current or future taxable years, and could increase our future U.S. tax expense. In addition, foreign governments or U.S. states may enact tax laws, or make changes to tax laws, that could result in further changes to taxation applicable to us and materially affect our operating results and financial condition.

As our growth continues, we may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect our future financial position, results of operations or cash flows.Lawsuits

Following announcement of the Merger Agreement and commencement of the Offer, the following lawsuits have been filed against the Company and members of the Company’s Board of Directors and certain members of senior management:

United States District Court Stockholder Litigation

On March 1, 2022, Danny Key, a purported stockholder of the Company, filed a complaint against the Company and each member of the Company’s Board of Directors in the United States District Court for the Southern District of New York, captioned Danny Key vs. Resonant, Inc., et al., Case No. 1:22-cv-01708 (the “Key Complaint”). The Key Complaint alleges that the defendants violated Sections 14(e), 14(d), and 20(a) of the Exchange Act by omitting and/or misrepresenting material information in the Solicitation/Recommendation Statement on Schedule 14D-9 of Resonant Inc. filed with the SEC on February 28, 2022 (the “Schedule 14D-9”) (concerning, among other things, the sale process, the Company’s financial projections, and financial valuation analyses provided by the Company’s financial advisors) in connection with the proposed transaction contemplated by the Offer. The Key Complaint seeks, among other things, an order enjoining consummation of the transaction; rescission or rescissory damages in the event the transaction is consummated; an order directing the Board of Directors to disseminate a revised Schedule 14D-9; and an award of plaintiff’s costs, including reasonable allowance for attorneys’ fees and experts’ fees.

Between March 4, 2022 and March 11, 2022, five additional complaints were filed in federal district court in New York and one additional complaint was filed in federal district court in Pennsylvania, in each case by purported stockholders of the Company: (i) Miles Weiss vs. Resonant, Inc., et al., Case No. 1:22-cv-01202-FB-PK (E.D.N.Y.) (the “Weiss Complaint”), (ii) Brian Jones vs. Resonant, Inc., et al., Case No. 1:22-cv-01855 (S.D.N.Y.) (the “Jones Complaint”), (iii) Ken Callen vs. Resonant, Inc., et al., Case No. 1:22-cv-01903 (S.D.N.Y.) (the “Callen Complaint”), (iv) Thomas Valenti vs. Resonant, Inc., et al., Case No. 1:22-cv-01244 (E.D.N.Y.) (the “Valenti Complaint”), (v) Benny Ruff vs. Resonant, Inc., et al., Case No. 2:22-cv-00861(E.D. Pa.) (the “Ruff Complaint”), and (vi) Jeffrey D. Justice, II vs. Resonant Inc. et al., Case No. 1:22-cv-01353 (E.D.N.Y.) (the “Justice Complaint”). The Weiss Complaint was voluntarily dismissed by the plaintiff on March 11, 2022.

Each of the Jones Complaint, the Valenti Complaint, the Ruff Complaint and the Justice Complaint asserts claims under Sections 14(e), 14(d), and 20(a) of the Exchange Act, and Rule 14d-9 promulgated thereunder, alleging, among other things, that defendants omitted certain material facts related to the transaction from the Schedule 14D-9. The Callen Complaint, which asserts claims under Sections 14(e) and 20(a) of the Exchange Act, alleges, in addition, that the disclosure regarding the Company’s financial projections is false and misleading in view of alleged prior statements by the Company on certain earnings calls. Each of the Jones Complaint, the Valenti Complaint, the Callen Complaint, the Ruff Complaint and the Justice Complaint seeks, among other things, to enjoin the defendants from consummating the transaction, rescissory damages should the transaction not be enjoined, and an award of attorneys’ fees and experts’ fees.

The Company and the Board believe that the allegations in each of the foregoing complaints are without merit and intend to defend their position. However, a negative outcome in any lawsuit could have a material adverse effect on the Company if it results in preliminary or permanent injunctive relief or rescission of the Merger Agreement. In addition, although the Company has directors and officers liability insurance, the Company anticipates that it will incur significant expense within its self-insured retention under that insurance. The Company is not currently able to predict the outcome of any

of the lawsuits with any certainty. Additional lawsuits may be filed against the Company, the Board of Directors or management in connection with the Merger Agreement and the Schedule 14D-9.

We are not party to any other legal proceedings. We may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As our growth continues, we may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect our future financial position, results of operations or cash flows.

Overview

We are a late-stage development company that develops technology for the RF front-end market. Our focus is on continuing to create innovative technology, engage new customers, expand the number of license contracts for filter designs and build the necessary infrastructure to support anticipated growth.

We plan to continue to develop IP associated with high frequency/high-wide bandwidth filters (XBAR®-based filters), to expand our IP and trade secret libraries, and further the development of our ~~ISN®~~WaveX™ multi-physics EDA platform. ~~While~~During wethe ~~remain~~third aquarter ~~filter~~of ~~design licensing company~~2019, we ~~are~~completed ~~also~~an ~~investigating~~investment ~~the~~and ~~potential~~commercial ofagreement ~~licensing~~with ~~part~~Murata orManufacturing ~~all~~Co., ofLtd., the first collaboration agreement leveraging our ~~ISN~~XBAR® ~~software~~IP. ~~design~~During ~~suite~~2020 ~~and~~we ~~certain~~continued ~~patents,~~the ~~including~~development IPof ~~associated~~filters ~~with~~under ~~our~~the ~~XBAR®~~commercial ~~filters~~agreement, toresulting ~~potential~~in ~~customers~~completion inof the ~~RFFE~~second ~~industry~~milestone ahead of schedule in October. ~~During~~This ~~the~~milestone ~~third~~is ~~quarter~~significant ofas ~~2019,~~it werecognizes ~~completed~~achieving anpredetermined ~~investment~~target performance, packaging and ~~commercial~~initial ~~agreement~~reliability. We expanded our relationship further by entering into agreements with Murata Manufacturing Co., Ltd., for the ~~first~~development ~~collaboration~~of ~~agreement~~additional ~~leveraging~~5G ~~our~~ XBAR® IPRF filters. In all licensing arrangements with our customers we intend to retain ownership of our technology, software, designs and related improvements. Our goal is to establish and leverage alliances with new and existing customers, who will help grow the market for our designs by integrating them with their own proprietary technology and products, or by using our software products for their own designs, thus combining their own particular strengths with ours to provide an extensive array of solutions. We continue to expand our foundry program, which allows fabless companies to enter into the filter business quickly and efficiently. It is through this foundry program that we expect to engage OEM’s and Independent Design House's (IDH's) directly to provide a significant cost and time to market advantage.

Our costs include employee salaries and benefits, compensation paid to consultants, capital costs for research and other equipment, costs associated with development activities including travel and administration, legal expenses, sales and marketing costs, general and administration expenses, and other costs associated with a late-stage development, publicly-traded technology company. We continue to add employees, as needed, to support the development of our ~~ISN®~~WaveX™ platform, applications and system test, research and development, as well as sales, marketing and administration functions, to support our efforts.

The amounts that we actually spend for any specific purpose may vary significantly and will depend on a number of factors including, but not limited to, our expected cash resources, the pace of progress of our commercialization and development efforts, actual needs with respect to product testing, research and development, market conditions, and changes in or revisions to our marketing strategies. In addition, we may invest in complementary products, technologies or businesses.

The COVID-19 Pandemic

The ongoing COVID-19 pandemic has negatively impacted the United States, Asia and Europe, the major markets in which we operate. Although we have seen improvements in the United States, the major markets in which we operate continue to experience COVID-19 cases and recurring shutdowns. The pandemic’s ultimate impact on our operations and financial performance depends in part on many factors not within our control and that vary by region, including, without limitation, restrictive governmental and business actions that continue to be taken in response (including travel restrictions and other workforce limitations).

If restrictions continue for an extended period of time, we may, among other issues, experience delays in product development, a decreased ability to support our customers, further disruptions in sales and marketing activities and an overall lack of productivity. Similarly, significant outbreaks, continued travel restrictions, stay-at-home or work remote conditions, or other restrictions may impact our customers’ ability to manufacture or deliver raw materials or provide key components or services, which could result in delays in the demand from our customers to produce designs. The pandemic may also impact the expansion of current and/or the roll out of new services which could impact our customers' demand for their products, which could reduce their demand for our products or services. While we don’t know and cannot quantify specific impacts, we expect we may be negatively affected if we encounter delays in our product development efforts, reductions in demand due to disruptions in the operations of our customers or their end customers, disruptions in local and global economies, volatility in the global financial markets, overall reductions in demand, or other COVID-19 ramifications.

We will continue to consider the potential impact of the COVID-19 pandemic on our business operations. Although no material impairment or other effects have been identified to date related to the COVID-19 pandemic, there is substantial uncertainty in the nature and degree of its continued effects over time. That uncertainty affects management’s accounting estimates and assumptions, which could result in greater variability in a variety of areas that depend on these estimates and assumptions as additional events and information become known.

Results of Operations

Comparison of the Years Ended December 31, ~~2020~~2021 and ~~2019~~2020

Revenues. Revenues consist primarily of the recognized portion of the transaction price associated with our contracts from customers recognized over time as the obligations under the terms of the contract are satisfied. Generally, the transaction price includes both upfront and milestone payments which we expect to receive in exchange for providing services. Revenues also include royalties from shipments of our licensed designs. For the years ended December 31, 2020 and 2019, we recognized $3.2 million and $0.7 million, respectively, of revenue. The increase was primarily a result of the collaboration and license agreement we signed in September 2019 with a major Tier 1 RF filter manufacturer. We have recorded $1.8 million of deferred revenue as of December 31, 2020, which we expect to recognize over the remainder of the contracts. Additionally, we expect to continue to recognize sales-based royalty revenue from our license agreements.

Revenues. Revenues consist primarily of the recognized portion of the transaction price associated with our contracts from customers recognized over time as the obligations under the terms of the contract are satisfied. Generally, the transaction price includes both upfront and milestone payments which we expect to receive in exchange for providing services. Revenues also include royalties from shipments of our licensed designs. For the years ended December 31, 2021 and 2020, we recognized $2.2 million and $3.2 million, respectively, of revenue. We derive a substantial majority of our revenues from a major Tier 1 RF filter manufacturer. We have recorded $6.8 million of deferred revenue as of December 31, 2021, which we expect to recognize over the remainder of the contracts, generally the next four years. Additionally, we expect to continue to recognize sales-based royalty revenue from our license agreements.

Research and Development. These expenses relate to direct engineering and other costs associated with the development and commercialization of our technology, including the development of filter designs for our customers, and consist primarily of the compensation costs of employees and consultants, including stock-based compensation, and to a lesser extent development related costs for facilities, equipment, software and supplies. We also include the costs for our intellectual property development program under research and development. This program focuses on patent strategy and invention extraction.

Research and development expenses increased $03.64 million from $1819.95 million in ~~2019~~2020 to $1922.59 million in ~~2020~~2021. The increase was athe ~~product~~result of higher development costs of $01.58 million related to our ~~ISN®~~WaveX™ and XBAR® technology development, $0.4 million of increased legal and other expenses related to our patent strategy program, and a $01.36 million increase in ~~software~~employment costs, ~~offset~~and bycompensation aexpense ~~$0.4 million reduction in employment costs~~ associated with headcount ~~reductions~~increases, ~~and~~offset by a decrease of $0.3 million ~~reduction~~of inseverance ~~travel~~related ~~expenses~~to ~~due~~a torestructuring ~~travel~~that ~~restrictions~~occurred ~~related~~in tothe ~~COVID-19~~first quarter of 2020. We anticipate that our research and development expenses will continue to increase due to higher development costs and additional headcount.

Sales, Marketing and Administration Expenses. These expenses relate to our sales and marketing efforts and our back-office support and include compensation costs of employees and consultants, including stock-based compensation. They also include expenses for facilities, travel expenses, telecommunications, investor relations, insurance and professional fees.

Sales, marketing and administration expenses increased $03.1 million, from $12.01 million in ~~2019~~2020 to $1215.12 million in ~~2020~~2021. The increase was primarily a product of ~~increases~~increased compensation expenses for employees and consultants of $02.40 million, ofincreased ~~compensation~~travel expense ~~associated~~of ~~with~~$0.1 ~~headcount~~million ~~changes~~as ~~and~~COVID ~~consultants~~restrictions ~~and~~have ~~$0.3~~started ~~million~~to oflift ~~costs~~and ~~associated~~other ~~with~~increased ~~being~~operating aexpenses ~~public~~including ~~company~~insurance, ~~offset~~investor byrelations, alegal ~~decrease~~and accounting of $0.69 million ~~of travel expenses due to travel restrictions related to COVID-19~~. We anticipate that our sales, marketing and administration expenses may continue to increase as a result of anticipated growth.

Interest and Investment Income. Interest and investment income decreased ~~by $0.2 million~~ from $~~0.3~~66,000 ~~million~~ in ~~2019~~2020 to ~~$0.1~~zero ~~million~~ in ~~2020~~2021 primarily due to decreased cash and investment balances and lower interest rates. We expect interest income to fluctuate in proportion to our cash and investment balances.

Income Taxes. We have earned minimal revenues and are currently operating at a loss. In addition to minimum taxes in the states where we conduct business, we are also responsible for income taxes in Switzerland related to the earnings of our foreign subsidiary, GVR. The provision for income taxes primarily represents the minimum taxes we incurred during the year.

Liquidity and Capital Resources

Table of Contents

Financing Activities

We have earned minimal revenues since inception. Our operations have been funded with initial capital contributions and proceeds from the sale of equity securities and debt.

As of December 31, ~~2020~~2021, we have raised aggregate gross proceeds of $~~137~~155.3 9 million through the use of loans, convertible debt and sales of equity ~~through~~pursuant anto ~~IPO~~our initial public offering, Atsecondary underwritten offerings, an at-the-~~Market~~market ~~offering~~equity program, private placement financings, and the exercise of warrants and ~~secondary offerings of our common~~ stock options.

We had current assets of $2521.79 million and current liabilities of $57.90 million as of December 31, ~~2020~~2021, resulting in working capital of $1914.89 million. This compares to working capital of $419.8 million as of December 31, ~~2019~~2020. The change in working capital is primarily the result of ~~proceeds~~use ~~from~~of ~~the~~cash ~~issuance~~in ofour ~~equity~~normal business operations offset by the ~~use~~proceeds offrom ~~cash~~the inissuance ~~our~~of ~~normal business operations~~equity.

As of December 31, ~~2020~~2021, our accumulated deficit totaled $~~150~~186.9 million. In the year ended December 31, ~~2020~~2021 our net loss totaled $2836.40 million and we used $2322.21 million of cash for operating activities, the purchase of property and equipment and expenditures for patents. To date we have not generated significant revenues to enable profitability. We expect to continue to incur significant losses. These factors raise substantial doubt regarding our ability to continue as a going concern. At December 31, ~~2020~~2021 we had cash and cash equivalents of $2521.02 million. Subsequent to December 31, 2020, but prior to publication of the financial statements included in this Form 10-K, we raised $4.1 million of cash from sales of common stock using our At-The-Market Equity Offering Sales Agreement. In the absence of a significant revenue increase we project these cash resources will provide sufficient funding into the first quarter of 2022. We are subject to the risks and uncertainties associated with a new business. We also have been impacted by the COVID-19 pandemic which has added additional risks and uncertainties. Our continuance as a going concern is dependent on future profitability. We are actively pursuing expanding our technology portfolio, increasing our revenue opportunities by completing deliverables under current customer contracts ~~and entering into new customer contracts~~, and efficiently managing operations and exploring cost saving opportunities. We may not be successful in these efforts. We may need to seek to raise additional capital from the sale of equity securities or incurrence of indebtedness. There can be no assurance that additional financing will be available to us on acceptable terms, or at all in which case we might be forced to make substantial reductions in our operating expenses which could adversely affect our ability to implement our business plan and ultimately our viability as a company. Even if available, such capital may be dilutive to existing stockholders. The accompanying consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

believe these cash resources, along with anticipated cash generated from existing customer contracts, will provide sufficient funding into the third quarter of 2022. We are subject to the risks and uncertainties associated with a new business. Our continuance as a going concern is dependent on future profitability. We are actively pursuing expanding our technology portfolio, increasing our revenue opportunities by completing deliverables under current customer contracts and entering into new customer contracts, and efficiently managing operations and exploring cost saving opportunities. We may not be successful in these efforts. As further described above, on February 14, 2022, the Company entered into a Merger Agreement for our proposed acquisition by Murata. If the merger is unable to be completed, we may need to seek to raise additional capital from the sale of equity securities or incurrence of indebtedness. There can be no assurance that additional financing will be available to us on acceptable terms, or at all in which case we might be forced to make substantial reductions in our operating expenses which could adversely affect our ability to implement our business plan and ultimately our viability as a company. Even if available, such capital may be dilutive to existing stockholders. The accompanying consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

The Merger Agreement for our proposed acquisition by Murata, described in the introduction to this management's discussion and analysis, places certain limitations on our use of cash and on our ability to raise capital through the sale of equity securities or incurrence of debt.

Cash Flow Analysis

Operating activities used cash of $2120.61 million in ~~2020~~2021 and $2021.76 million in ~~2019~~2020. The ~~increase~~decrease is primarily the result of ~~increased~~an ~~working~~increase ~~capital~~in ~~changes~~non-cash items, deferred revenue and salary accruals, partially offset by an increase in net loss primarily driven by an increase in operating expenses.

Investing activities used cash of $12.60 million in ~~2020~~2021 and ~~provided cash of~~ $151.6 million in ~~2019~~2020. In ~~2020~~both years, the cash used was a result of purchases of property and equipment and expenditures for patents. In 2019, the cash provided was a result of the redemptions of investments held to maturity in excess of purchases of investments held to maturity, offset by the cash used to purchase property and equipment and expenditures for patents.

Financing activities provided cash of $3718.52 million in ~~2020~~2021 and $1137.35 million in ~~2019~~2020. The cash provided in ~~2020~~2021 was the result of proceeds from the sales of equity securities from anour ~~underwritten~~at-the-market ~~public~~program ~~offering~~ and ~~from~~exercises ~~our~~of ~~At-the-Market~~stock ~~program~~options. The cash provided in ~~2019~~2020 was the result of ~~net~~ proceeds from the ~~sale~~sales of equity securities infrom ~~our~~an ~~private~~underwritten ~~placement~~public ~~financing~~offering ~~completed in September 2019~~ and ~~net proceeds~~ from our at-the-market ~~exercises of warrants for cash~~program.

Off-Balance Sheet Transactions

We do not have any off-balance sheet arrangements.

Contractual Obligations and Known Future Cash Requirements

Indemnification Agreements

In the ordinary course of business, we may enter into agreements of varying scope and terms pursuant to which we agree to indemnify customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of breach of such agreements, services to be provided by us or from intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with directors and certain officers and employees that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors, officers or employees. No demands have been made upon us to provide indemnification under such agreements and there are no claims that we are aware of that could have a material effect on our consolidated balance sheets, consolidated statements of comprehensive loss, consolidated statements of stockholders’ equity or consolidated statements of cash flows.

Our material cash requirements include the following contractual and other obligations.

Purchasing Commitments

We have non-cancelable purchasing commitments that we incur in the ordinary course of business. The purchase commitments covered by these agreements are for less than one year and aggregate to $0.7 million as December 31, 2021.

We lease various office facilities, including our corporate headquarters in Austin, Texas, as well as our offices in Goleta, California, Burlingame, California and Anyang, South Korea under operating lease agreements. The terms of the lease agreements provide for rental payments on a graduated basis. We recognize rent expense on a straight-line basis over the lease periods.

Critical Accounting Policies and Estimates

Our critical accounting estimates are included in our significant accounting policies as described in Note 2 of the consolidated financial statements included in Item 8, Financial Statements and Supplemental Data, of this Annual Report on Form 10-K. Those consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America. Critical accounting estimates are those that we believe are most important to the portrayal of our financial condition and results of operations. The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. Our estimates are evaluated on an ongoing basis and are drawn from historical operations, current trends, future business plans and other factors that management believes are relevant at the time our consolidated financial statements are prepared. Actual results may differ from our estimates. Management believes that the following accounting estimates reflect the more significant judgments and estimates we use in preparing our consolidated financial statements.

Revenue Recognition—We recognize revenue in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers.

Revenue is recognized upon the transfer of control of promised goods or services to the customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. We are required to use estimates to determine the transaction price in the contract as well as the time over which we will satisfy the performance obligations. The determination of the transaction price may include estimates of amounts we expect to receive, including milestones that we may achieve which would result in additional payments upon achievement. These estimates are used for recognition of our revenue primarily related to upfront non-refundable fees received in connection with filter design projects with customers. Our performance obligation is to design a licensable filter in accordance with customer specifications. For the years ended December 31, 2021 and 2020, the majority of our revenue was recognized over time as services were provided. We recognize revenue over the course of the estimated design development phase based on efforts expended to date. Significant estimation is involved in determining the efforts that will be expended for the contract duration. The estimation of costs over the contract period have a material impact on the revenue we recognize over the contract period and they require significant judgement on the part of management. At the end of each reporting period, we reassess our measure of progress and adjust revenue when appropriate.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and the Board of Directors

Resonant Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance ~~sheet~~sheets of Resonant Inc. and subsidiaries (the Company) as of December 31, 2021 and 2020, the related consolidated statements of comprehensive loss, stockholders’ equity, and cash flows for the ~~year~~years ~~ended~~then ~~December 31~~ended, ~~2020,~~ and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, ~~2020~~2021, in conformity with U.S. generally accepted accounting principles.

Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses from operations, and expects to continue to incur significant losses, that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our ~~audit~~audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our ~~audit~~audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our ~~audit~~audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our ~~audit~~audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our ~~audit~~audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our ~~audit~~audits ~~provides~~provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit ~~matters~~matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Estimation of ~~total~~ labor costs to be incurred for the Murata ~~contract~~contracts

As discussed in Notes 2 and 3 to the consolidated financial statements, in September 2019 the Company entered into a collaboration and license agreement with Murata Manufacturing Co., Ltd (Murata), and in September 2021 the Company entered into an addendum to this agreement with Murata. ~~Revenue~~ ~~for~~Under the Murata ~~contract~~agreements, isthe ~~recognized~~Company ~~over~~enters ~~time~~individual ~~and~~statements ~~represents~~of awork ~~substantial~~for ~~majority~~the ofdesign ~~total~~and ~~revenues~~development of ~~$3.16~~products, ~~million~~which ~~for~~the Company identifies as separate contracts (the ~~year~~agreements ~~ended~~and ~~December~~related ~~31,~~statements ~~2020.~~of work are collectively referred to as the Murata Contracts). The Company recognizes revenue for the performance obligations in the Murata ~~contract~~Contracts over the estimated design development period based on the level of effort expended, as measured by costs incurred relative to total expected ~~costs, as the services are performed.~~

We identified the evaluation of the estimate of labor costs to be incurred for the Murata Contracts as a critical audit matter. Subjective auditor judgment was required to evaluate the estimates of remaining labor costs to complete the performance obligations in the Murata Contracts due to a high degree of estimation uncertainty.

The following are the primary procedures we performed to address this critical audit matter:

•we inquired of operational and financial personnel of the Company to evaluate progress to date, the estimate of remaining labor costs to be incurred, and factors impacting the amount of time and cost to complete the ~~contract~~performance obligations in the Murata Contracts, including the assessment of the nature and complexity of the work to be performed.

•we inspected correspondence, if any, between the Company and ~~the~~Murata ~~customer~~ as part of our evaluation of contract progress.

•we compared the Company’s original or prior period estimate of ~~total~~ labor costs to be incurred to the actual labor costs incurred to-date plus the estimate of remaining labor costs to be incurred to assess the Company’s ability to accurately estimate labor costs.

Notes to Consolidated Financial Statements

NOTE 1—ORGANIZATION AND DESCRIPTION OF BUSINESS

Overview

Resonant Inc. is a late-stage development company located in Austin, Texas, with offices in Goleta, California, ~~Burlingame~~ San Mateo, California and Anyang, South Korea. We were incorporated in Delaware in January 2012 as a wholly owned subsidiary of Superconductor Technologies Inc., or STI. Resonant LLC, a limited liability company, was formed in California in May 2012. We changed our form of ownership from a limited liability company to a corporation in an exchange transaction in June 2013, when we commenced business. We are the successor of Resonant LLC. We completed our initial public offering, or IPO, on May 29, 2014. On July 6, 2016 we acquired all of the issued and outstanding capital stock of GVR Trade S.A, or GVR. GVR is a wholly owned subsidiary of Resonant Inc. The company operates in one market and segment, the radio frequency filter design industry.

The innovative software platform we continue to develop is based on fundamentally new technology that we call ~~Infinite Synthesized Networks®~~WaveX™, ~~or ISN®,~~ to configure and connect resonators, the building blocks of RF filters. Currently, we are leveraging ~~ISN®~~WaveX™ to develop designs targeted for either the Surface Acoustic Wave (SAW) or Temperature Compensated, Surface Acoustic Wave (TC-SAW) manufacturing processes. We also enabled ~~ISN®~~WaveX™ for BAW designs, which has resulted in our invention of a novel resonator structure based on a combination of interdigital transducer (IDT) and piezoelectric layer, XBAR®, which exhibits performance parameters suitable for 5G,5-7GHz WiFi and UWB applications - high frequency operation, large bandwidth and high power reliability.

Using ~~ISN®~~WaveX™ we have developed an IP portfolio of more than ~~300~~415 patents filed or issued, with more than ~~150~~265 filed or issued targeting XBAR®, 5G and high frequency WiFi applications. In addition, with continued requirements for increasing numbers of filter designs our innovative software platform addresses the need for increased designer efficiency, reduced time to market and lower unit costs in the designs of filters for radio frequency, or RF Front-Ends for the mobile device, Customer Premise Equipment (CPE) and Infrastructure industries. The RF Front-End, or RFFE, is the circuitry responsible for analog signal processing and is located between the device’s antenna and its digital circuitry. Filters are a critical component of the RFFE used to select desired radio frequency signals and reject unwanted signals.

We believe licensing our designs is the most direct and effective means of validating our IP and IP related libraries and demonstrating the power and accuracy of our ~~ISN®~~WaveX™ multi-physics EDA platform. Our target customers make part, or all of, the RFFE. We intend to retain ownership of our IP, trade secrets and designs, and we expect to be compensated through license fees and royalties either prepaid at contract inception or based on sales of RFFE filters that incorporate our IP, trade secrets and designs.

Capital Resources and Liquidity

As of December 31, ~~2020~~2021, our accumulated deficit totaled $~~150~~186.9 million. In the year ended December 31, ~~2020~~2021 our net loss totaled $2836.40 million and we used $2322.21 million of cash and investments for operating activities, the purchase of property and equipment and expenditures for patents. To date we have not generated significant revenues to enable profitability. We expect to continue to incur significant losses. These factors raise substantial doubt regarding our ability to continue as a going concern. At December 31, ~~2020~~2021 we had cash and cash equivalents of $2521.02 million. ~~Subsequent~~In tothe ~~December~~absence ~~31, 2020, but prior to publication~~ of ~~the~~additional ~~financial~~customer ~~statements on this Form 10-K~~contracts, we ~~raised~~project ~~$4.1~~these ~~million of~~ cash ~~from~~resources, ~~sales~~along ofwith ~~common~~anticipated ~~stock~~cash ~~using~~generated ~~our~~from ~~At-The-Market~~existing ~~Equity~~customer ~~Offering~~contracts, ~~Sales Agreement. In the absence of a significant revenue increase we project these cash resources~~ will provide sufficient funding into the ~~first~~third quarter of 2022. We are subject to the risks and uncertainties associated with a new business. ~~We have also been impacted by the COVID-19 pandemic which has added additional risks and uncertainties.~~ Our continuance as a going concern is dependent on future profitability. We are actively pursuing expanding our technology portfolio, increasing our revenue opportunities by completing deliverables under current customer contracts and entering into new customer contracts, and efficiently managing operations and exploring cost saving opportunities. We may not be successful in these efforts. WeAs further described in Note 15 - Subsequent Events, on February 14, 2022 we entered into a Merger Agreement for our proposed acquisition by Murata. If the merger is unable to be completed, we may need to seek to raise additional capital from the sale of equity securities or incurrence of indebtedness. There can be no assurance that additional financing will be available to us on acceptable terms, or at all in which case we might be forced to make substantial reductions in our operating expenses which could adversely affect our ability to implement our business plan and ultimately our viability as a company. Even if available, such capital may be dilutive to existing stockholders. The accompanying consolidated financial statements have been prepared on a going concern basis which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

NOTE 2—SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Use of Estimates—The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or U.S. GAAP. Significant estimates made in preparing these financial statements include (a) assumptions to calculate the fair values of financial instruments, warrants and equity instruments and other liabilities and the deferred tax asset valuation allowance; (b) the useful lives for depreciable and amortizable assets and (c) the estimated efforts to be expended, as well as our ability to achieve milestones, in connection with our revenue contracts. Actual results could differ from those estimates. Additionally, the global economic effects resulting from the COVID-19 pandemic may cause changes to estimates that would have a material impact on our financial statements, particularly with respect to timing of revenue recognition due to delays in meeting our performance obligations ~~and collectability of our accounts receivable~~. As of the date of issuance of these financial statements, our results of operations have not been significantly impacted by the COVID-19 pandemic, however, we continue to monitor the situation. In the opinion of management, all adjustments, including normal recurring accruals considered necessary for a fair presentation, have been included.

Consolidation - The accompanying financial statements include the accounts of the Company and its wholly-owned subsidiary, GVR. All significant intercompany balances and transactions have been eliminated.

Cash and Cash Equivalents—We consider all liquid instruments purchased with a maturity of three months or less to be cash equivalents.

Concentration of Credit Risk—We maintain bank accounts at one U.S. financial institution. The U.S. bank accounts are insured by the Federal Deposit Insurance Corporation (FDIC) for up to $250,000 per account owner. GVR, our wholly owned Swiss-based subsidiary maintains checking accounts at one major national financial institution. Additionally, we maintain a checking account with a very minimal balance at one bank in South Korea, which is used to fund payroll and rent in South Korea. Management believes we are not exposed to significant credit risk due to the financial position of the depository institutions in which our deposits are held.

Restricted Cash—Restricted cash at December 31, ~~2020~~2021 and ~~2019~~2020 consists of a pledged mutual fund account which is held as collateral against a letter of credit issued in May 2018 in connection with the lease of our offices in ~~Cremona~~Goleta, California. The letter of credit was reissued in November 2020 due to a change in the property owner. No changes were made to the terms of the letter of credit. The terms of the letter of credit allow for a step-down of $50,000 annually upon performance of certain events, primarily no late or defaulted payments. See also Note 109 - Leases, for further details.

Fair Value of Financial Instruments—We measure certain financial assets and liabilities at fair value based on the exit price notion, or price that would be received for an asset or paid to transfer a liability, in an orderly transaction between the market participants at the measurement date. The carrying amounts of our financial instruments, including cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities, approximate fair value due to their short maturities.

Accounts Receivable—Trade accounts receivable are stated net of allowances for doubtful accounts. Management estimates the allowance for doubtful accounts based on review and analysis of specific customer balances that may not be collectible, customer payment history and any other customer-specific information that may impact collectability of the receivable. Accounts are considered for write-off when they become past due and when it is determined that the probability of collection is remote. There was no allowance for doubtful accounts at December 31, ~~2020~~2021 and ~~2019~~2020.

Property and Equipment—Property and equipment consists of leasehold improvements associated with our corporate offices, software purchased during the normal course of business, equipment and office furniture and fixtures, all of which are recorded at cost. Depreciation and amortization is recorded using the straight-line method over the respective useful lives of the assets ranging from ~~three~~two to five years. Leasehold improvements are amortized over the shorter of lease term or useful life. Long-lived assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable.

Intangible Assets, net—Intangible assets are recorded at cost and amortized over the useful life. In the case of business combinations, intangible assets are recorded at fair value. At December 31, ~~2020~~2021 and ~~2019~~2020, intangible assets, net, includes patents and a domain name and other intangible assets purchased as part of our acquisition of GVR, including customer relationships, technology and a trademark. We capitalize certain patent filing costs up to the point of issuance and then amortize the cost over the life of the patent. Costs associated with maintenance or renewal of existing patents are expensed as incurred. Intangible assets are reviewed for impairment whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. In certain cases, patents may expire or be abandoned as they no longer have a probable economic

4543

value. In such cases we write off the capitalized patent costs as patent abandonment costs which are included in research and development expenses.

Goodwill—Goodwill represents the difference between the price paid to acquire GVR and the fair value of the assets acquired, net of assumed liabilities. We review goodwill for impairment annually and whenever events or circumstances indicate that the carrying amount of these assets may not be recoverable. As of January 1, 2019, we have adopted ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which simplifies the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test.

Revenue Recognition—Revenue is recognized upon the transfer of control of promised goods or services to customers, generally over time, in an amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue consists primarily of the recognized portion of up-front, non-refundable, prepaid royalties received in connection with filter design projects with customers. Our performance ~~obligation~~obligations isinclude material rights of the customer for future designs and also current obligations to design a licensable filter in accordance with customer specifications. The license of ~~the~~any completed design is considered part of ~~this~~the performance obligation as the design and licensing of the filter are highly interdependent. We recognize revenue ~~over the course of the design development phase as our customers are able to benefit~~ from our design services ~~as they are provided, primarily by marketing the in-process design to their customers. We recognize revenue from our design services~~ based on efforts expended to date. At the end of each reporting period, we reassess our measure of progress and adjust revenue when appropriate. We record the expenses related to these projects in the periods incurred and they are included in research and development expense.

InWe ~~most~~evaluate ~~cases~~upfront non-refundable prepaid royalties associated with design development contracts to determine whether any of the prepaid amount is attributable to a material right of the customer, or if the payment is solely attributable to the current design contract. If a material right exists, then the upfront payment may require allocation of the amount between the amount attributable to the material right and the amount attributable to the current design contract. In cases that require allocation, we use estimated stand-alone selling prices, as well as other factors, to make the allocation. Amounts attributable to the material right of the customer are initially deferred and then once a design contract is entered into, they are combined with other payments in the contract and are considered the full transaction price for the contract. Upfront non-refundable ~~payments~~prepaid ~~related~~royalties attributed to a design ~~development~~contract are generally recognized over a multi-year period of 12one ~~months~~ to 18four ~~months~~years as that is the amount of time it generally takes us to develop a design; however, the actual amount of time depends on the complexity of the filter being designed. Contracts ~~generally include non-refundable fees, or prepaid royalties, and~~ may also include milestone payments based upon the successful completion of certain deliverables. Milestone payments represent variable consideration, and we use the "most likely amount" approach to determine the amount we ultimately expect to receive.

Upon completion of design services, our customers retain a license over the completed design. The license will typically last for a minimum of two years, and in many cases for the life of the design. Some contracts also include royalties that are sales-based, and we recognize royalty revenue upon shipment, by our customer, of products that include our licensed design. Payment is generally due within 30 days.

We apply the exemptions available in ASC 606 to not disclose information about 1) remaining performance obligations that have original expected durations of one year or less and 2) variable consideration that is a sales-based or usage-based royalty. Our performance obligations related to material rights of the customer are expected to be performed in more than one year as the customer has discretion over the timing of entering into additional contracts.

Research and Development—Costs and expenses that can be clearly identified as research and development are charged to expense as incurred in accordance with ASC Topic 730-10, Research and Development.

Operating Leases—We lease office space and research facilities under operating leases. Certain lease agreements contain free or escalating rent payment provisions. ~~As of January 1, 2019, we have adopted ASU No. 2016-02, Leases (Topic 842) as well as other clarifying and practical updates issued under Leases (Topic 842) applicable to us.~~

We determine if an arrangement is a lease at lease inception. Operating leases are included in right-of-use (“ROU”) lease assets, other current liabilities (current portion of lease obligations), and long term lease obligations on our balance sheets. ROU lease assets represent our right to use an underlying asset for the lease term and lease obligations represent our obligation to make lease payments arising from the lease. Operating ROU lease assets and obligations are recognized at the commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The ROU lease asset also includes any lease payments made and excludes lease incentives. We evaluate renewal options at lease inception and on an ongoing basis, and include renewal options which we are reasonably certain to exercise in our expected lease term when classifying leases and measuring lease liabilities. We allocate the consideration between lease and ~~nonlease~~non-lease components and exclude ~~nonlease~~non-lease components from our recognized lease assets and liabilities.

Minimum lease payments, including scheduled rent increases, are recognized as lease expenses on a straight-line basis over the applicable lease term. We recognize lease expenses within research and development and sales, marketing and administration expenses on a straight-line basis over the lease term.

We are not party to any leases for which we are the lessor.

46Finance Lease—The finance lease right-of-use asset represents our right to use an underlying asset for the lease term and the finance lease liability represents the present value of lease payments not yet paid. Interest expense on the finance lease is recorded over the lease term and is presented in interest expense, based on the effective interest method. The right-of-use asset is amortized over the term of the related lease.

Finance Lease—The finance lease asset represents our right to use an underlying asset for the lease term and the finance lease liability represents the present value of lease payments not yet paid. Interest expense on the finance lease is recorded over the lease term and is presented in interest expense, based on the effective interest method. The right of use asset is amortized over the term of the related lease.

Stock-Based Compensation—We account for employee stock options in accordance with ASC Topic 718, Compensation-Stock Compensation. We use the Black-Scholes option valuation model for estimating fair value at the date of grant.

We account for restricted stock units issued at fair value, based on the market price of our stock on the date of grant~~, net of estimated forfeitures~~. Compensation expense is recognized for the portion of the award that is ultimately expected to vest over the period during which the recipient renders the required services to the Company generally using the straight-line single option method.

We recognize compensation expense for restricted stock units with market conditions using a graded vesting model, based on the probability of the market condition being met~~, net of estimated pre-vesting forfeitures~~.

In the case of award modifications, we ~~account for the modification in accordance with ASU No.2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting, whereby we~~ recognize the effect of the modification in the period the award is modified.

As of January 1, 2019, we adopted ASU No. 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Non-employee Share-Based Payment Accounting, which aligns the accounting of share-based payment awards issued to employees and non-employees. The adoption did not materially impact our condensed consolidated financial statements.

Stock-based compensation expense is included in research and development expenses and general and administrative expenses.

Earnings Per Share, or EPS—EPS is computed in accordance with ASC Topic 260, Earnings per Share, and is calculated using the weighted average number of common shares outstanding during each period. Diluted EPS assumes the conversion, exercise or issuance of all potential common stock equivalents unless the effect is to reduce a loss or increase the income per share. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options (using the treasury stock method), the exercise of warrants (using the if-converted method) and the vesting of restricted stock unit awards.

Income Taxes—We account for income taxes in accordance with ASC Topic 740, Income Taxes, or ASC 740, which requires the recognition of deferred tax assets and liabilities for the future consequences of events that have been recognized in our consolidated financial statements or tax returns. The measurement of the deferred items is based on enacted tax laws. In the event the future consequences of differences between financial reporting bases and the tax bases of our assets and liabilities result in a deferred tax asset, ASC 740 requires an evaluation of the probability of being able to realize the future benefits indicated by such asset. A valuation allowance related to a deferred tax asset is recorded when it is more likely than not that some portion or the entire deferred tax asset will not be realized. As part of the process of preparing our consolidated financial statements, we are required to estimate our income tax expense in each of the jurisdictions in which we operate. We also assess temporary differences resulting from differing treatment of items for tax and accounting differences. We record a valuation allowance to reduce the deferred tax assets to the amount of future tax benefit that is more likely than not to be realized.

Reclassifications—Certain amounts in the consolidated balance sheet and the consolidated statement of cash flows for the years ended December 31, 2020 and 2019 have been reclassified to conform to the current year presentation.

Foreign Currency Translation—The Swiss Franc has been determined to be the functional currency for the net assets of our Swiss-based subsidiary. We translate the assets and liabilities to U.S. dollars at each reporting period using exchange rates in effect at the balance sheet date and record the effects of the foreign currency translation in accumulated other comprehensive loss in shareholders' equity. We translate the income and expenses to U.S. dollars at each reporting period using the average exchange rate in effect for the period and record the effects of the foreign currency translation as other comprehensive income (loss) in the consolidated statements of comprehensive loss. Gains and losses resulting from foreign currency transactions are included in net loss in the consolidated statements of comprehensive loss.

Recent Accounting Pronouncements

Credit Losses—In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments- Credit Losses (Topic 326). In April and November 2019, and February 2020, the FASB issued implementation amendments to the June 2016 ASU (collectively, the amended guidance). The amended guidance replaced the current incurred loss methodology for credit losses with a current expected credit loss ("CECL") model, which requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The amended guidance expanded the information that an entity must consider in developing its expected credit loss estimates. Additionally, the updates amended the accounting for credit losses for purchased financial assets with a more-than-significant amount of credit deterioration since origination. The amended guidance requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimated credit losses. Early

with a current expected credit loss ("CECL") model, which requires the measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The amended guidance expanded the information that an entity must consider in developing its expected credit loss estimates. Additionally, the updates amended the accounting for credit losses for purchased financial assets with a more-than-significant amount of credit deterioration since origination. The amended guidance requires enhanced disclosures to help investors and other financial statement users better understand significant estimates and judgments used in estimated credit losses. Early adoption is permitted. The guidance is effective for us in January 2023. We have no plan to early adopt the guidance and are currently evaluating the impact, which we believe will be immaterial to our consolidated financial statements.

With the exception of the new standards discussed above, there have been no other new accounting pronouncements that have significance, or potential significance, to our consolidated financial statements.

NOTE 3—REVENUE RECOGNITION

Contract Liabilities - Our contract liabilities consist of deferred revenue, which represents the revenue associated with remaining performance obligations within our customer contracts.

We derive a substantial majority of our revenue from a single customer. Effective September 30, 2019 we entered into a collaboration and license agreement with Murata Manufacturing Co., Ltd. Pursuant to the collaboration agreement, we have agreed with Murata to collaborate on the development of proprietary circuit designs using our XBAR® technology, and we licensed to Murata rights for products in four specific radio frequencies, or bands. Murata has agreed to pay us up to an aggregate of $9.0 million of total contract consideration in the form of pre-paid royalties for the licensed designs and certain other intellectual property developed in the collaboration, payable in installments over a multi-year development period, with each installment conditional upon our achievement of certain milestones and deliverables acceptable to Murata in its discretion. Murata may terminate the collaboration agreement at any time upon thirty (30) days prior written notice to us.

Murata’s rights to our XBAR® technology are exclusive for a period of 30 months, through March 2022, during which period we may not grant to any third party the right to develop, make, have made, use, sell, offer for sale or import any filter or resonator produced through the use of the XBAR® technology for use in mobile communication devices.

48Under the collaboration agreement, the first payment of $2.0 million was a non-refundable upfront payment received on October 11, 2019. The second payment of $2.5 million was received on September 29, 2020 upon the achievement of the second milestone. As of December 31, 2021 there is $4.5 million remaining potential contract consideration for the achievement of certain milestones outlined in the collaboration and license agreement.

~~Under~~On September 30, 2021, we entered into Addendum 1 to the collaboration agreement with Murata, which amends and supplements the ~~first~~collaboration ~~payment~~agreement to provide for the development of $2XBAR®-based designs for up to four additional bands.0 ~~million~~For ~~was~~rights to these additional bands, Murata has agreed to pay us a $4.0 million non-refundable upfront payment, ~~received~~which was paid on ~~October~~November 1110, ~~2019.~~2021, ~~The~~and ~~second~~up ~~payment~~to an aggregate of between $28.50 million ~~was~~and ~~received~~$36.0 million in pre-paid royalties and other fees, with the amount of the aggregate payments determined based on ~~September~~the 29complexity of the filter designs selected for development. The future payments will be made in two installments per band over a multi-year development period, ~~2020~~with each installment conditional upon ~~the~~our achievement of certain milestones and deliverables acceptable to Murata in its discretion. Murata retains the ~~second~~right ~~milestone~~to terminate the collaboration agreement and addendum at any time upon thirty (30) days prior written notice to us. We evaluated whether or not Addendum 1 should be treated as a contract modification and we determined that Addendum 1 represented a separate contract and is not a modification to the existing contract. We also considered whether Addendum 1 provided material rights of the customer for future designs and determined that the customer does have material rights to enter into future design development contracts. We allocated the $4.0 million non-refundable upfront payment to each of the four bands at $1.0 million per band as the prepayment provides Murata with a material right to receive future services. Addendum 1 allows Murata with certain time periods in which to choose the next design. Once a design is chosen, the amount

In accordance with the guidance of ASC 606, we are required to evaluate the variable consideration within the contract, primarily the milestone payments, and assess the likelihood of achievement in determining our transaction price. Additionally, we must assess whether the variable consideration is constrained and whether recording such variable revenue may result in a significant reversal of revenue due to uncertainties. We continue to evaluate variable consideration for inclusion in the transaction price, and ultimately the revenue recognized, at each reporting period. We recognize revenue for the Murata contract over the estimated design development period, based on the level of effort expended over total expected costs, as the services are performed. For the periods ended December 31, 2020 and 2019, we have determined that the milestone payments due upon achievement of certain performance criteria are constrained and are thus not included in the transaction price. Therefore, revenue related to those milestone payments has not been recognized. Revenue recognition related to each milestone payment will commence once the constraint is lifted. Consequently, revenue recognition related to the Murata contract will vary from quarter to quarter. During the years ended December 31, 2020 and 2019, we recognized $2.7 million and $0.4 million, respectively, of revenue related to the collaboration and license agreement.46

The first non-~~TO-MATURITY~~refundable upfront installment payment of $3.0 million related to this agreement was received on November 10, 2021.

In accordance with the guidance of ASC 606, we are required to evaluate the variable consideration within the contract, primarily the milestone payments, and assess the likelihood of achievement in determining our transaction price.

Stock Options

Options granted in ~~2020~~2021 and ~~2019~~2020 have a term of ten years and vest quarterly over sixteen quarters.

We estimated the fair value of stock options awarded during the years ended December 31, ~~2020~~2021 and ~~2019~~2020 using the Black-Scholes option valuation model. The fair values of stock options granted for the years were estimated using the following assumptions:

To the extent that actual forfeitures differ from our estimates, the difference is recorded as athey ~~cumulative adjustment in the period the estimates were revised~~occur. For the year ended December 31, 2020, we applied a forfeiture rate of ten percent, which is reflected in our stock-based compensation expense related to stock options. ~~For the year ended December 31, 2019, we applied a forfeiture rate of six percent, which is reflected in our stock-based compensation expense related to stock options.~~

As of December 31, 2020, there was $4.9 million of unrecognized compensation expense related to unvested restricted stock unit agreements which is expected to be recognized over a weighted-average period of approximately 2.1 years. For restricted stock unit awards subject to graded vesting, we recognize compensation cost on a straight-line basis over the service period for the entire award. The total fair value of awards vested during the years ended December 31, 2020 and December 31, 2019 was $6.2 million and $5.2 million, respectively.

Market-based Awards

In August 2016, we granted 250,000 market-based restricted stock units to an executive. The restricted stock units are subject to market-based vesting requirements, measured quarterly, based on the average of (a) the average high daily trading price of our common stock for each trading day during the last month of the applicable calendar quarter and (b) the average low daily trading price of our common stock for each trading day during the last month of the applicable calendar quarter, each as reported by The Nasdaq Stock Market, LLC. The restricted stock units are eligible to be earned on a quarterly basis based on a linear interpolation of the applicable share price, or in the case of a liquidation event, on the day of (or in connection with) such liquidation event based on the applicable transaction price. The share price on the date of issuance was $5.06 per share.

linear interpolation of the applicable share price, or in the case of a liquidation event, on the day of (or in connection with) such liquidation event based on the applicable transaction price. The share price on the date of issuance was $5.06 per share.

In June 2019, the market-based award was modified to increase the number of restricted stock units to 500,000 and to decrease the applicable share price. Additionally, the performance period was extended to September 30, 2022. The share price on the date of modification was $2.73 per share.

Once earned, the restricted stock units vest 50% on the date such restricted stock units become earned and 50% on September 30, 2022. To determine the fair value of the award, we used a Monte Carlo simulation, which simulates future stock prices for the Company and, hence, shares vested, pursuant to the award. A key input into the model is the expected volatility for our stock. This estimate considered the historical volatility of our stock as well as the stock price volatility of guideline public companies. The fair value was determined to be $74,000 at the original grant date, and was $147,000 as of the modification date. For each of the years ended December 31, ~~2020~~2021 and ~~2019~~2020, we recognized $42,000 ~~and $37,000~~ of stock compensation expense, ~~respectively,~~ in connection with this award, which is included in sales, marketing and administration expenses. The unamortized expense related to this award is $7331,500 and is expected to be recognized over 10.875 years.

In December 2019, we granted 200,000 market-based restricted stock units to an executive. The restricted stock units are subject to the same market-based vesting requirements discussed for the award granted in August 2016 and modified in June 2019. The share price on the date of issuance was $2.15 per share and the fair value was determined to be $26,000 using a Monte Carlo simulation. For each of the years ended December 31, ~~2020~~2021 and ~~2019~~2020, we recognized $9,000 ~~and $2,000~~ of stock compensation expense, ~~respectively,~~ in connection with this award, which is included in research and development expenses. The unamortized expense related to this award is $156,~~000~~500 and is expected to be recognized over 10.875 years.

Incentive Bonus Awards

We provide eligible employees, including executives, the opportunity to earn bonus awards upon achievement of predetermined performance goals and objectives. The purpose is to reward attainment of company goals and/or individual performance objectives, with award opportunities expressed as a percentage of base salary. Bonuses can be measured and paid quarterly and/or annually, and are paid in cash, equity or a combination of cash and equity, in the discretion of our compensation committee. If paid in the form of equity, the expense is included in the above disclosures for stock options or restricted stock units as applicable. As of December 31, ~~2019,~~2021 ~~there~~and ~~was $343,000 of accrued incentives that were settled in the form of restricted stock units issued March, 2020. As of~~ December 31, 2020, there were no accrued incentives that were settled in the form of equity.

NOTE 109—LEASES

We lease facilities under two non-cancelable operating leases. The leases expire between January 2022 and November 2024 and include renewal provisions for two to five years, provisions which require us to pay taxes, insurance, maintenance costs or provisions for minimum rent increases. We ~~also~~lease lab equipment under a finance lease. Additionally, we lease facilities and equipment under short-term agreements for a period of 12 months or less and recognize the payments straight-line over the lease term. All of the information presented below, with the exception of total lease costs, relates to our two non-cancelable operating leases and a finance lease with periods of 12 months or greater.

On May 1, 2020 we entered into an amendment for one of our non-cancelable facilities operating leases, under which certain rent payments were deferred and the term of the lease was extended by three months to November 30, 2024. The base rent was deferred for three months and the deferred amount will be repaid over the remaining balance of the modified lease term. In addition, operating expenses were deferred for three months and the deferred amount ~~will~~was be paid upon true-up of operating expenses, which isoccurred ~~estimated to occur~~ in ~~early~~April 2021. We evaluated the amendment under the provisions of ASU No. 2016-02, Leases (Topic 842), as well as subsequently issued interpretive guidance, and ~~have~~ elected to account for the concessions as if no changes to the lease contract were made. In our evaluation we considered the total amount of lease payments both before and after the amendment and determined they are substantially the same. As of December 31, 2020, the deferred base rent is included in operating lease liabilities and the deferred operating expenses are included in accrued expenses.

One facility operating lease requires us to maintain a cash security deposit of $50,000 and also a $105,000 letter of credit in favor of the lessor. The letter of credit was originally for $200,000 at lease inception and steps down $50,000 at each anniversary date if there have been no monetary defaults. The letter of credit is secured by a pledge in favor of the issuing bank of a $105,000 mutual fund account which is classified as restricted cash in our balance sheet.53

We recorded a full valuation allowance against our U.S. federal and state net deferred tax assets at December 31, ~~2020~~2021 and December 31, ~~2019~~2020. In determining the need for a valuation allowance, we reviewed all available evidence pursuant to the requirements of FASB ASC Topic 740, Income Taxes. Based upon our assessment of all available evidence, we have concluded that it is more likely than not that the net deferred tax assets will not be realized. For the year ended December 31, ~~2020~~2021, the valuation allowance increased by $710.78 million. For the year ended December 31, ~~2019~~2020, the valuation allowance increased by $97.17 million.

As of December 31, ~~2020~~2021, we had federal net operating loss carryforwards of approximately $~~125~~159.54 million, state net operating loss carryforwards of approximately $~~127~~162.91 million and foreign net operating loss carryforwards of $4052,000 in Switzerland. In accordance with the 2017 Tax Act, the $78112.75 million federal net operating loss carryforwards generated on or after January 1, 2018 will not expire and will be limited to 80% usage. The federal net operating loss carryforwards generated prior to January 1, 2018 will begin to expire in 2033, and the state net operating loss carryforwards will begin to expire in 2033. Our ability to utilize federal net operating loss carryforwards may be limited in the event that a change in ownership, as defined in Section 382 of the Internal Revenue Code, occurs in the future. States may vary in its conformity to Section 382 of the Internal Revenue Code. In the event a change of ownership occurs, it will limit the annual usage of the carryforwards in future years. In 2014 and 2017 ownership changes, as defined in Section 382 of the Internal Revenue Code, occurred which resulted in annual limitations on our federal net operating loss carryforwards; however, we believe it is more likely than not that none of the federal net operating loss carryforwards will expire as a result of the limitations under Section 382.

We recognize interest and penalties related to income tax matters in income taxes, and there were none during the years ended December 31, ~~2020~~2021 and ~~2019~~2020. As of December 31, ~~2020~~2021 and ~~2019~~2020, no liability for unrecognized tax benefits was required to be reported.

6056

ASC 740 guidance requires us to identify, evaluate and measure all uncertain tax positions taken or to be taken on tax returns and to record liabilities for the amount of these positions that may not be sustained, or may only partially be sustained, upon examination by the relevant taxing authorities. Although we believe that our estimates and judgments are reasonable, actual results may differ from these estimates. Some or all of these judgments are subject to review by the taxing authorities. For the year ended December 31, ~~2020~~2021, we had uncertain tax positions of $1.0 2 million as a result of research and development tax credits claimed on our annual tax returns. We had ~~no significant~~ uncertain tax positions of $1.0 million for the year ended December 31, ~~2019~~2020.

Our annual income taxes and the determination of the resulting deferred tax assets and liabilities involve a significant amount of judgment. Our judgments, assumptions and estimates relative to current income taxes take into account current tax laws, their interpretation of current tax laws and possible outcomes of future audits conducted by domestic tax authorities. We operate within federal and state taxing jurisdictions and are subject to audit in these jurisdictions. These audits can involve complex issues which may require an extended period of time to resolve. We are currently not being examined by any tax authorities. We are subject to taxation in the United States, California, Massachusetts and Switzerland. As of December 31, ~~2020~~2021, our tax years remain open to examination by the taxing authorities for all years since our incorporation in 2013.

NOTE 1211—COMMITMENTS AND CONTINGENCIES

Purchase Commitments—We have non-cancelable purchasing commitments that we incur in the ordinary course of business. The purchase commitments covered by these agreements are for less than one year and aggregate to $10.57 million as of December 31, ~~2020~~2021.

Legal Proceedings—We ~~are not party to any legal proceedings. We~~ may, from time to time, be party to litigation and subject to claims incident to the ordinary course of business. As our growth continues, we may become party to an increasing number of litigation matters and claims. The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect our future financial position, results of operations or cash flows.

Legal fees and other costs associated with such actions are expensed as incurred. We assess, in conjunction with our legal counsel, the need to record a liability for litigation and contingencies. Litigation accruals are recorded when and if it is determined that a loss related matter is both probable and reasonably estimable. Material loss contingencies that are reasonably possible of occurrence, if any, are subject to disclosure. We evaluate developments in legal proceedings and other matters on a quarterly basis. As of December 31, ~~2020~~2021 and ~~2019~~2020, there was no litigation or contingency with at least a reasonable possibility of a material loss. No losses have been recorded during the years ended December 31, ~~2020~~2021 and ~~2019~~2020, respectively, with respect to litigation or loss contingencies.

Intellectual Property Indemnities—We indemnify certain customers and manufacturers against liability arising from third-party claims of intellectual property rights infringement related to our products. These indemnities may appear in license agreements, development agreements and manufacturing agreements, may not be limited in amount or duration and generally survive the expiration date of the contract. Given that the amount of any potential liabilities related to such indemnities cannot be determined until an infringement claim has been made, we are unable to determine the maximum amount of losses that we could incur related to such indemnifications.

Director and Officer Indemnities and Contractual Guarantees—We have entered into indemnification agreements with our directors and executive officers, which require us to indemnify such individuals to the fullest extent permitted by Delaware law. Our indemnification obligations under such agreements are not limited in amount or duration. Certain costs incurred in connection with such indemnifications may be recovered under certain circumstances under various insurance policies. Given that the amount of any potential liabilities related to such indemnities cannot be determined until a lawsuit has been filed, we are unable to determine the maximum amount of losses that we could incur relating to such indemnities.

We have also entered into severance and change in control agreements with certain of our executives. These agreements provide for the payment of specific compensation benefits to such executives upon the termination of their employment with us.

Guarantees and Indemnities—In the normal course of business, we are occasionally required to undertake indemnification for which we may be required to make future payments under specific circumstances. We review our exposure under such obligations no less than annually, or more frequently as required. The amount of any potential liabilities related to such obligations cannot be accurately determined until a formal claim is filed. Historically, any such amounts that become payable have not had a material negative effect on our business, financial condition or results of operations. We maintain general and product liability insurance which may provide a source of recovery to us in the event of an indemnification claim.

The term commences on January 17, 2022 and expires on January 31, 2023 with an option to renew the sublease for an additional one-year term for rent of $13,250 per month. Alan Howe, a member of our board of directors, is a director of Sonim Technologies, and Robert Tirva, a member of our board of directors, is an executive officer of Sonim Technologies.

NOTE 13—EMPLOYEE BENEFIT PLAN

We have a 401(k) Savings Retirement Plan that covers substantially all domestic employees who meet the plan’s eligibility requirements and provides for an employee elective contribution and employer matching contributions.

We recorded matching contributions to the retirement plan of $~~494~~524,000 and $~~497~~494,000 for the years ended December 31, ~~2020~~2021 and ~~2019~~2020, respectively.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The phrase “disclosure controls and procedures” refers to controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Securities Exchange Act of 1934, as amended, or the Exchange Act, such as this Annual Report on Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the U.S. Securities and Exchange Commission, or SEC. Disclosure controls and procedures are also designed to ensure that such information is accumulated and communicated to our management, including our chief executive officer, or CEO, and chief financial officer, or CFO, as appropriate to allow timely decision regarding required disclosure.

Our management, with the participation of our CEO and CFO, has evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), as of December 31, ~~2020~~2021, the end of the period covered by this Annual Report on Form 10-K. Based on such evaluation, our CEO and CFO have concluded that as of December 31, ~~2020~~2021, our disclosure controls and procedures were designed at a reasonable assurance level and were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the SEC, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate, to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles.

Our management, with the participation of our CEO and CFO, has assessed the effectiveness of the internal control over financial reporting as of December 31, ~~2020~~2021. In making this assessment, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013 Framework). Based on this evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, ~~2020~~2021.

This Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm on our internal control over financial reporting due to an exemption established for smaller reporting companies.

Changes in Internal Controls over Financial Reporting

There was no change in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the quarter ended December 31, ~~2020~~2021 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Narrative Disclosure to Summary Compensation Table

The compensation committee of the board is responsible for the executive compensation programs for our executive officers and reports to the board on its discussions, decisions and other actions. Typically, our chief executive officer makes recommendations to our compensation committee, often attends committee meetings and is involved in the determination of compensation for the executive officers that report to him, except that he does not make recommendations as to his own compensation. Our chief executive officer makes recommendations to our compensation committee regarding short-term and long-term compensation for all executive officers, excluding himself, based on our results, an individual executive officer’s contribution toward these results and performance toward individual goal achievement. Our compensation committee then reviews the recommendations and other data and makes decisions as to total compensation for each executive officer other than the chief executive officer, as well as each individual compensation component. The compensation committee makes recommendations to the board regarding compensation for the chief executive officer. The independent members of the board make the final decisions regarding executive compensation for our chief executive officer.

Compensation Elements

Our compensation package for executive officers consists of base salary, annual incentive (bonus) awards, and long-term equity-based compensation. The executive officers are also eligible to participate in all of our employee benefit plans. We also provide in certain circumstances, a sign-on bonus to executive officers, which may be applied against and reduce any other bonus to which the executive is entitled for one or more fiscal years and must be repaid if the executive officer voluntarily terminates employment with us other than for good reason within one year of commencement of employment.

Base Salary. We provide competitive base salaries to pay for day-to-day service in light of each individual’s duties and responsibilities, experience, expertise and individual performance. Individual salary levels are determined based on assessments of internal job responsibilities, experience in the role, and market levels for comparable positions. Salary increases also are determined based on market levels of compensation and an assessment of individual and team performance for the year.

Annual base salaries as of December 31, 2020 and 2021 and as of March 14, 2022 for the named executive officers are as follows:


Executive	2020 Annual Base Salary		2021 Annual Base Salary		2022 Annual Base Salary
George Holmes	$	400,000	$	425,000	$	425,000
Martin McDermut	$	307,340	$	314,716	$	333,599
Dylan Kelly	$	285,000	$	300,000	$	316,500

Incentive (Bonus) Awards. We provide eligible employees, including our named executive officers, the opportunity to earn bonus awards upon achieving predetermined performance goals and objectives. The purpose is to reward attainment of company goals and/or individual performance objectives, with award opportunities expressed as a percentage of base salary. Bonuses can be measured and paid quarterly and/or annually, and are paid in cash, equity or a combination of cash and equity, in the discretion of our compensation committee.

2021 Incentive Bonus Program. During 2021, our executive officers, including our named executive officers, participated in the 2021 incentive bonus program. The program provided for the award of quarterly and/or annual bonuses to our employees and executive officers (other than our chief executive officer) if certain performance goals, based on company-

Table of Contents

wide billings, expenses and certain other individual non-monetary targets, were attained in quarterly and annual performance periods during our 2021 fiscal year. The awards contained a combination of service conditions and performance conditions based on the achievement of specified performance thresholds. The awards were based on each individual’s annual salary multiplied by a bonus multiplier percentage which had been determined by our compensation committee. The plan also allowed for additional discretionary awards to non-executive employees up to 10% of the total base salaries of non-executive employees. Our chief executive officer was eligible for the award of an annual bonus if certain performance goals, based on company-wide billings, expenses and stock price performance, were attained during the fiscal 2021 annual performance period. The bonuses for the first three quarters were paid in restricted stock, and the fourth quarter and annual bonuses were paid in cash. The number of shares underlying equity awards granted to each employee in payment of quarterly bonuses was determined based on the performance bonus amount to be paid in equity, divided by our closing stock price on the grant date.

Our named executive officers received the following quarterly and annual incentive bonus awards during 2021:

The letters have no specific duration and provide for at-will employment. Each of our named executive officers may be entitled to receive severance benefits under a severance and change in control agreement, as described below.

Table of Contents

Severance and Change in Control Agreements

We have entered into severance and change in control agreements with participating employees, including our named executive officers, which provide these employees with severance benefits upon the employee’s termination of employment in certain circumstances with certain additional benefits following a change in control of Resonant. These benefits provide the participating employees with enhanced financial security and incentive to remain with Resonant notwithstanding their at-will employment with us and the possibility of a change in control.

Termination Without Change in Control

If we terminate the participant’s employment with Resonant for a reason other than cause, the participant becoming disabled or the participant’s death, and the termination does not occur within twenty-four months immediately following a “change in control,” the participant will receive the following severance benefits:

Accrued Compensation: The participant will receive all accrued but unpaid paid time off, expense reimbursements, wages, and other benefits due to the participant under any Resonant -provided plans, policies, and arrangements.

Severance Payment: All participants will receive severance for a specified number of months of the participant's base salary then in effect immediately prior to the date of the participant’s termination of employment, less all required tax withholdings and other applicable deductions, payable as soon as practicable following the participant’s termination of employment. Messrs. Holmes, McDermut and Kelly, our named executive officers, are each entitled to receive 18 months of base salary severance.

Target Bonus Payment: The participant will receive a lump-sum severance payment equal to 100% of the participant’s full target bonus as in effect for the fiscal year in which the termination occurs, which amount for all participants other than the CEO will be pro-rated for the portion of the fiscal year that the participant was employed by us.

Continued Health Insurance Benefits: We will reimburse the participant for premiums for coverage of the participant and his or her eligible dependents pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) (at the coverage levels in effect immediately prior to termination of employment) until the earliest to occur of (A) a period of twelve (12) months from the last date of employment with us, (B) the date upon which the participant becomes eligible for coverage under a health, dental, or vision insurance plan of a subsequent employer, and (C) the date the participant or his or her dependents cease to be eligible for COBRA coverage.

Equity: All of the participant’s unvested and outstanding equity awards that would have become vested had the participant remained in our employ for the twelve (12) month period following termination of employment shall immediately vest and become exercisable as of the date of termination, and the participant will have six months following termination of employment in which to exercise any stock options, stock appreciation rights, or similar rights to acquire our common stock.

Outplacement Benefits. If requested by the participant, we will pay the expense for outplacement benefits provided by a service to be determined by us for a period of six (6) months, up to a maximum dollar value of five thousand dollars ($5,000) per participant.

Termination Following Change in Control

If during the twenty-four (24) month period immediately following a change in control of Resonant, (x) we terminate the participant’s employment with us for a reason other than cause, the participant becoming disabled or the participant’s death, or (y) the participant resigns his employment for good reason, then the participant will receive the following benefits from us in lieu of the benefits described above under “Termination Without Change in Control”:

Severance Payment: All participants will receive severance for a specified number of months of the participant's base salary then in effect. Messrs. Holmes, McDermut and Kelly, our named executive officers, are each entitled to receive 18 months of base salary severance.

Target Bonus Payment: The participant will receive a lump sum severance payment equal to 100% of the participant’s full target bonus for the fiscal year in effect at the date of such termination of employment (or, if greater, as in effect for the fiscal year in which the change in control occurs).

Continued Health Insurance Benefits: We will reimburse the participant for premiums for coverage of the participant and his or her eligible dependents pursuant to the COBRA (at the coverage levels in effect immediately prior to termination of employment) until the earliest to occur of (A) a period of twelve (12) months from the last date of employment with us, (B) the

Table of Contents

date upon which the participant becomes eligible for coverage under a health, dental, or vision insurance plan of a subsequent employer, and (C) the date the participant or his or her dependents cease to be eligible for COBRA coverage.

Equity: All of the participant’s unvested and outstanding equity awards shall immediately vest and become exercisable as of the date of termination, and the participant will have six (6) months following termination of employment in which to exercise any stock options, stock appreciation rights, or similar rights to acquire our common stock.

Pension Benefits and Nonqualified Deferred Compensation

We do not provide a pension plan for our employees, and none of our named executive officers participated in a nonqualified deferred compensation plan in 2021.

401(k) Plan

We maintain a tax-qualified retirement plan, or the 401(k) plan, that provides eligible employees with an opportunity to save for retirement on a tax-advantaged basis. Eligible employees are able to participate in the 401(k) plan as of the first day of the month following the date they meet the 401(k) plan’s eligibility requirements, and participants are able to defer up to 100% of their eligible compensation subject to applicable annual Code limits. All participants’ interests in their deferrals are 100% vested when contributed. The 401(k) plan permits us to make matching contributions and profit sharing contributions to eligible participants. We have implemented a matching program, which is limited to 5% of base salary. In 2021, we made matching contributions of $524,000 into the plan.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

~~The information required by this item is incorporated by reference to the disclosure appearing under the headings “~~Security Ownership of Certain Beneficial Owners and Management” and “Equity Compensation Plan Information” in our Proxy Statement for the 2021 Annual Meeting of Stockholders to be filed with the SEC within 120 days of the fiscal year ended December 31, 2020.

The following table sets forth certain information with respect to the beneficial ownership of our common stock for:

•each of our named executive officers;

•each of our directors;

•all of our executive officers and directors as a group; and

•each person, or group of affiliated persons, who beneficially owned more than 5% of our common stock.

We have determined beneficial ownership in accordance with the rules of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares of common stock that they beneficially owned, subject to applicable community property laws.

The information for each beneficial owner is as of March 14, 2022, unless otherwise indicated for greater than five percent (5%) stockholders who are not officers or directors of Resonant. We have based percentage ownership of our common stock on 67,186,080 shares of our common stock outstanding as of March 14, 2022. In computing the number of shares of common stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of common stock subject to options held by the person that are currently exercisable or exercisable within 60 days of March 14, 2022, as well as all shares of common stock issuable pursuant to restricted stock units held by the person that are subject to vesting conditions expected to occur within 60 days of March 14, 2022. However, we did not deem such shares outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Resonant Inc., 10900 Stonelake Blvd, Suite 100, Office 02-130, Austin, TX 78759.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

~~The~~Reportable ~~information required by this item is incorporated by reference to the disclosure appearing under the heading “Certain Relationships and~~ Related Party Transactions” and “Board of Directors and Corporate Governance -- Director Independence” in our Proxy Statement for the 2021 Annual Meeting of Stockholders to be filed with the SEC within 120 days of the fiscal year ended December 31, 2020.

We describe below transactions, and series of related transactions, since January 1, 2020 to which we were or will be a party, in which:

•the amounts involved exceeded or will exceed $120,000; and

•any of our directors, executive officers, or beneficial holders of more than 5% of any class of our capital stock, or their immediate family members, had or will have a direct or indirect material interest.

Other than as described below, there has not been, nor is there any currently proposed, transaction or series of related transactions to which we have been or will be a party other than compensation arrangements, which are described where required under the headings “Board of Directors and Corporate Governance - Director Compensation Table” and “Executive Compensation.”

Indemnification Agreements

We have entered into indemnification agreements with each of our current and former directors and executive officers and certain key employees. The indemnification agreements and our amended and restated certificate of incorporation and amended and restated bylaws require us to indemnify our current and former directors and officers to the fullest extent permitted by Delaware law.

Policies and Procedures for Related Party Transactions

Our audit committee has the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. Our policy regarding transactions between us and related persons provides that a related person is defined as a director, executive officer, nominee for director or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and any of their immediate family members. Our audit committee charter provides that our audit committee shall review and approve or disapprove any related party transactions.

Director Independence

Our common stock is listed on the NASDAQ Capital Market. Under the rules of NASDAQ, independent directors must comprise a majority of a listed company’s board of directors. In addition, the rules of NASDAQ require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and governance committees be independent. Under the rules of NASDAQ, a director will only qualify as an ‘‘independent director’’ if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our board of directors has undertaken a review of the independence of each director and considered whether each director has a material relationship with us that could compromise such director’s ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our board of directors has determined that Messrs. Fox, Howe, Jack Jacobs, Joshua Jacobs and Tirva, and Ms. Rankin are ‘‘independent directors’’ as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of NASDAQ. Because Mr. Holmes is employed by Resonant, he does not qualify as independent. Additionally, the Board concluded that Mr. Caballero does not qualify as independent due to the nature and significance of his consulting relationship with Resonant.

~~The~~Fees ~~information~~Paid ~~required by this item is incorporated by reference~~ to ~~the disclosure appearing under the heading “Ratification of Appointment of~~ Independent Registered Public Accounting ~~Firm” in our Proxy Statement for the 2021 Annual Meeting of Stockholders to be filed with the SEC within 120 days of the fiscal year ended December 31, 2020.~~Firms

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services

Consistent with requirements of the SEC and the Public Company Accounting Oversight Board, or PCAOB, regarding auditor independence, our audit committee is responsible for the appointment, compensation and oversight of the work of our independent registered public accounting firm. In recognition of this responsibility, our audit committee has a policy for the pre-approval of all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services.

Before engagement of the independent registered public accounting firm for the next fiscal year’s audit, the independent registered public accounting firm submits to the audit committee for approval a detailed description of services expected to be rendered during that year for each of the following categories of services:

•Audit services. Audit services include the annual financial statement audit (including required quarterly reviews) and other procedures required to be performed by the independent auditor to form an opinion on our consolidated financial statements. Audit services also include, as necessary, the attestation engagement for the independent auditor’s report on management’s report on internal controls for financial reporting. Other audit services may include services associated with SEC registration statements, periodic reports and other documents filed with the SEC.

•Audit-related services. Audit-related services are assurance and related services that are reasonably related to the performance of the audit or review of our financial statements or that are traditionally performed by the independent auditor.

•Tax Services. Tax services include services related to tax compliance, tax planning and tax advice.

•All Other Services. All other services are those services not described in the other categories that are not prohibited by SEC rules.

The audit committee pre-approves particular services or categories of services on a case-by-case basis. During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the services must be pre-approved by the audit committee, or as permitted, the audit committee chair, before the independent registered public accounting firm is engaged. Pre-approval fee levels or budgeted amounts for all services to be provided by the independent registered public accounting firm are established annually by the audit committee. Any proposed services exceeding these levels or amounts require specific pre-approval by the audit committee, or the audit committee chair. All fees paid for the fiscal years ended December 31, 2021 and 2020 were pre-approved by the audit committee in accordance with the process described in the policy above.
