1.The Company and Summary of Significant Accounting Policies

Nature of Operations

QT Imaging Holdings, Inc. (“we,” “our,” “us,” “QT Imaging,” “QT Imaging Holdings,” or the “Company”) is incorporated in Delaware with its headquarters in Novato, California. We are a medical device company engaged in research, development, and commercialization of innovative body imaging systems using low frequency sound waves. We strive to improve global health outcomes. Our strategy is predicated upon the fact that medical imaging is critical to the detection, diagnosis, and treatment of disease and that it should be safe, affordable, accessible, and centered on the patient’s experience. Our initial product is a breast imaging system, the QT Imaging Breast Acoustic CT™ Scanner (the “Breast Acoustic CT Scanner”).

GigCapital5, Inc. (“GigCapital5”), our predecessor, was incorporated in Delaware on December 8, 2022. GigCapital5 was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. Our business combination (the “Business Combination”) was consummated on March 4, 2024, and in connection with the Business Combination, GigCapital5 changed its corporate name to QT Imaging Holdings, Inc.

Basis of Presentation and Principles of Consolidation

Our unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The unaudited condensed consolidated financial statements, including the condensed notes thereto, are unaudited and exclude some of the disclosures required in audited financial statements. The unaudited condensed consolidated balance sheet as of December 31, 2025 has been derived from the audited consolidated financial statements as of that date, but do not include all of the information and footnotes required by U.S. GAAP for complete financial statements.

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments and eliminations, consisting only of normal recurring adjustments necessary for a fair presentation in conformity with U.S. GAAP. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026 or any future period. The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2025.

The unaudited condensed consolidated financial statements include the accounts of QT Imaging Holdings, Inc. and its consolidated subsidiaries, QT Imaging, Inc. and QT Ultrasounds Labs, Inc.

All intercompany balances and transactions have been eliminated in consolidation.

Reverse Stock Split

On August 19, 2025 our stockholders approved an amendment to our Second Amended and Restated Certificate of Incorporation to effect a reverse split of the outstanding shares of our common stock, par value $0.0001 per share, at a specific ratio within a range of 2:1 to 20:1, with the specific ratio to be fixed within this range by our Board of Directors in its sole discretion without further stockholder approval (the “Reverse Stock Split”). Our Board of Directors fixed the Reverse Stock Split ratio at 3:1, such that each three shares of common stock were combined and reconstituted into one share of common stock effective October 23, 2025. In connection with the Reverse Stock Split, the CUSIP number of the common stock changed to 746962307. The common stock began trading on the OTCQB Venture Market on a reverse split-adjusted basis on October 24, 2025. Except as noted, all share, stock option, warrant, and per share amounts throughout these unaudited condensed consolidated financial statements have been retroactively adjusted to reflect this Reverse Stock Split.

Uplisting to Nasdaq

Effective January 28, 2026, upon meeting all of the Nasdaq Stock Market LLC (“Nasdaq”) listing requirements, our common stock was uplisted from the OTCQB Venture Market to the Nasdaq Capital Market and began trading under the ticker symbol “QTI.”

Liquidity

As of March 31, 2026, we had cash and cash equivalents of $6.9 million. We have incurred net operating losses and negative cash flows from operations since our inception and had an accumulated deficit of $56.4 million as of March 31, 2026. During the three months ended March 31, 2026, we incurred a net loss of $3.4 million and used $3.7 million of cash in operating activities. We expect to continue to incur losses, and our ability to achieve and sustain profitability will depend on the achievement of sufficient revenue to support our cost structure. We may never achieve profitability and, unless and until we do, we will need to continue to raise additional capital.

On February 26, 2025, we entered into a credit agreement (the “Lynrock Lake Credit Agreement”) that provided a senior secured term loan (the “Lynrock Lake Term Loan”) with Lynrock Lake Master Fund LP (“Lynrock Lake”) in the aggregate principal amount of $10.1 million. On August 26, 2025, we and Lynrock Lake entered into the First Amendment to the Lynrock Lake Credit Agreement (the “Lynrock Lake Amended Credit Agreement”) to add an additional tranche of $5.0 million (“Tranche B”) to the Lynrock Lake Term Loan and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant. On October 6, 2025, we repaid the $5.0 million under Tranche B of the Lynrock Lake Term Loan, plus accrued interest and the Tranche B Premium. On May 12, 2026, we and Lynrock Lake entered into the Second Amendment to the Lynrock Lake Credit Agreement (the “Second Amended Credit Agreement”) to extend the maturity date of the Lynrock Lake Term Loan from March 31, 2027 to March 31, 2029, and to increase the interest rate from 10% to 12% per annum. Refer to Note 5 - Long-Term Debt for more information.

During the year ended December 31, 2025 and the three months ended March 31, 2026, we completed a series of Private Investment in Public Entity (“PIPE”) transactions, where we received cash in exchange for the issuance of shares of common stock plus warrants for the purchase of common stock. Refer to Note 8 - Stockholders’ Equity for more information.

•On April 24, 2025, we entered into a Securities Purchase Agreement (the “First Securities Purchase Agreement”) in an amount of approximately $0.5 million from related persons. We used the net proceeds from the offering for working capital purposes.

•On May 12, 2025, we entered into a Securities Purchase Agreement (the “Second Securities Purchase Agreement”) in an amount of approximately $0.2 million. We used the net proceeds from the offering for working capital purposes.

•On October 3, 2025, we entered into a Securities Purchase Agreement (the “Third Securities Purchase Agreement”) in an amount of approximately $18.2 million, before deducting the offering expenses payable by us. We used the net proceeds from the offering for working capital purposes and to repay Tranche B (as defined below) of the Lynrock Lake Term Loan.

•On January 22, 2026, we entered into a Securities Purchase Agreement (the “Fourth Securities Purchase Agreement” and together with the First Securities Purchase Agreement, the Second Securities Purchase Agreement and the Third Securities Purchase Agreement, the “PIPE Investments”) in an amount of approximately $0.2 million from a related party. We used the net proceeds from the offering for working capital purposes.

During the years ended December 31, 2025 and 2024 and the three months ended March 31, 2026, we entered into several distribution agreements which provided us with Minimum Order Quantities (“MOQs”) as follows:

•On June 18, 2024, we entered into the Distribution Agreement between QT Imaging and NXC Imaging, Inc. (“NXC”), as first amended on December 11, 2024 and further amended on March 28, 2025 (the “Amended NXC

Distribution Agreement”), which provides us with MOQs of 60 scanners in 2026, representing revenue of more than $28 million in 2026.

•On August 21, 2025, we entered into a Distribution Agreement, as amended on February 25, 2026 (the “Gulf Medical Distribution Agreement”) with Gulf Medical Co. (“GMC”), a corporation organized and existing under the laws of Saudi Arabia, for an initial term of three years. Under the terms of the Gulf Medical Distribution Agreement, we granted to GMC the exclusive right to market, advertise, and sell our Breast Acoustic CT Scanner and the QTI Cloud SaaS platform subscriptions in Saudi Arabia, with MOQs of 20 scanners in 2026, 32 scanners in 2027, and 40 scanners in 2028, for a total minimum of 92 scanners, representing revenue of more than $51 million in 2026 through 2028, upon regulatory approval from the Saudi Food and Drug Authority (“SFDA”) in Saudi Arabia.

•On January 19, 2026, we entered into a Distribution Agreement (the “Al Naghi Distribution Agreement”) with Al Naghi Medical Co. (“Al Naghi”), a corporation organized and existing under the laws of the United Arab Emirates (the “UAE”), for an initial term of three years. Under the terms of the Al Naghi Distribution Agreement, we granted to Al Naghi the exclusive right to market, advertise, and sell our Breast Acoustic CT Scanner and the QTI Cloud SaaS platform subscriptions in the UAE, with MOQs of 7 scanners in 2026, 16 scanners in 2027, and 20 scanners in 2028, for a total minimum of 43 scanners, representing revenue of more than $24 million in 2026 through 2028, upon regulatory approval from the Emirates Drug Establishment (“EDE”) in the UAE, which was received on March 17, 2026.

We believe that the additional cash received from the Lynrock Lake Term Loan, the extension of the maturity date of the Lynrock Lake Term Loan to March 2029, the additional cash received from the PIPE Investments, and the expected revenue from MOQs per the Amended NXC Distribution Agreement, the Gulf Medical Distribution Agreement, and the Al Naghi Distribution Agreement will be sufficient to fund our current operating plan for at least the next 12 months.

Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, purchasing inventory to meet our growth plan, and the timing and cost to enhance commercialized existing products. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us, or at all. Any additional debt financing obtained by us in the future could also involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. Additionally, if we raise additional funds through further issuances of equity, convertible debt securities, or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of us, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to grow or support our business and to respond to business challenges could be significantly limited.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, and expenses and the related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. In addition, any change in these estimates or their related assumptions could have an adverse effect on our operating results.

Summary of Significant Accounting Policies

Other than the policies discussed above, there have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 25, 2026 (our “Annual Report”) that have had a material impact on our unaudited condensed consolidated financial statements.

Recently Issued Accounting Pronouncements Adopted

In December 2023, the Financial Accounting Standard Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disclosure of specific categories in the effective tax rate reconciliation and additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. This guidance is effective on a prospective or retrospective basis for annual periods beginning after December 15, 2025 for us, with early adoption permitted. We adopted this guidance effective January 1, 2026 on a prospective basis. The adoption of this standard did not have a material impact on our financial position, results of operations, or cash flows. We expect to provide any required income tax disclosures for annual reporting periods in our financial statements for the year ending December 31, 2026.

In November 2024, the FASB issued ASU 2024-04, Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments. This standard clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion and the application of the induced conversion guidance to a conversion debt instrument. It also clarifies that the incorporation, elimination, or modification of a daily volume-weighted average price (“VWAP”) formula does not automatically cause a settlement to be accounted for as an extinguishment. This standard will become effective on a prospective or retrospective basis for interim reporting periods and annual periods beginning after December 15, 2025. Early adoption is permitted. We adopted this guidance effective January 1, 2026 on a prospective basis. The adoption of this standard did not have a material impact on our financial position, results of operations, or cash flows.

In July 2025, the FASB issued ASU 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient to measure credit losses on accounts receivable and contract assets. The ASU is effective for annual periods beginning after December 15, 2025, and interim periods within those annual reporting periods. Early adoption is permitted. We adopted this guidance effective January 1, 2026 on a prospective basis. The adoption of this standard did not have a material impact on our financial position, results of operations, or cash flows.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The standard requires that public business entities disclose additional information about specific expense categories in the notes to financial statements for interim and annual reporting periods. The standard will become effective for the fiscal year ended December 31, 2027 and interim unaudited condensed consolidated financial statements thereafter and may be applied prospectively to periods after the adoption date or retrospectively for all prior periods presented in the financial statements, with early adoption permitted. We are currently evaluating the impact of this guidance on the disclosures within our consolidated financial statements.

In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract. This standard provides a scope exception to exclude from derivative accounting non-exchange-traded contracts with underlyings that are based on operations or activities specific to one of the parties to the contract, if the contract does not have (i) variables based on a market rate, market price, or market index, (ii) variables based on the price or performance of a financial asset or financial liability of one of the parties to the contract, (iii) contracts or features involving the issuer’s own equity, and (iv) call options and put options on debt instruments. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within those annual reporting periods. Early adoption is permitted. We are currently evaluating the timing of the adoption and the impact of the new standard on our consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. This standard establish the accounting for a government grant received by a business entity. In addition, this standard requires a business entity to provide disclosures, including the nature of the government grant received, the accounting policies used to account for the grant, and significant terms and conditions of the grant. The standard is effective for interim and annual reporting periods beginning after December 15, 2028 on a modified prospective approach, a modified retrospective approach, or a retrospective approach. Early adoption is permitted. We are currently evaluating the timing of the adoption and the impact of the new standard on our consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. This standard provides a comprehensive list of interim disclosures that are required by GAAP and includes a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027 on a prospective or retrospective basis. Early adoption is permitted. We are currently evaluating the timing of the adoption and the impact of the new standard on our consolidated financial statements and related disclosures.

2.Business Combination

Merger Earnout Consideration Shares

Pursuant to the Second Amendment to Business Combination Agreement dated September 21, 2023, we are obliged to issue a maximum of 3,000,000 shares of our common stock (the “Merger Earnout Consideration Shares”) if certain triggering events and conditions are achieved. The conditions for the 2024 Earnout Shares and the 2025 Earnout Shares were not met and therefore no shares were issued during the years ended December 31, 2024 and 2025.

Promptly following the date on which we file our quarterly report on Form 10-Q with respect to our fiscal quarter ended September 30, 2026 with the SEC, an aggregate of 833,333 Merger Earnout Consideration Shares (the “2026 Earnout Shares”) will be issued to our former stockholders if, and only if, during the twelve months ended September 30, 2026, (i) we have revenue of at least $30.0 million as set forth in the unaudited condensed consolidated financial statements included in the periodic reports filed by us with the SEC with respect to such twelve month period, or (ii) the VWAP of shares of common stock equals or exceeds $45.00 per share for twenty (20) of any thirty (30) consecutive trading days on the Nasdaq exchange; provided, that the 2026 Earnout Shares will increase by 166,667 (to an aggregate of 1,000,000) Merger Earnout Consideration Shares if at least one of the following milestones is achieved on or prior to such filing date: (i) we have obtained a formal Food and Drug Administration (“FDA”) clearance of our open angle scanner, which remains in full force and effect as of such filing date; or (ii) we receive net positive results in bona fide clinical trials, conducted in accordance with generally accepted industry standards, for our open angle scanner, as reported no later than the filing date of our quarterly report on Form 10-Q for the third quarter of 2026.

As of both March 31, 2026 and December 31, 2025, the liability related to the Merger Earnout Consideration Shares was $2.2 million. Refer to Note 3 - Fair Value Measurements for more information.

3.Fair Value Measurements

The fair value of our financial assets and liabilities reflects management’s estimate of amounts that we would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of our assets and liabilities, we seek to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs which are supported by little or no market activity and which are significant to the fair value of the assets or liabilities.

The following table presents information about our assets and liabilities that are measured at fair value on a recurring basis as of March 31, 2026 and December 31, 2025, and indicates the fair value hierarchy of the valuation inputs we utilized to determine such fair value (in thousands):



	Level	March 31, 2026		December 31, 2025
Assets:
Certificate of deposit	2	$	50	$	50
Liabilities:
Warrant liability	2	$	276	$	103
Earnout liability	3	$	2,160	$	2,210

Warrant Liability

Working Capital Note Warrants, Private Warrants, and Public Warrants

We determined that the warrants that were a constituent part of (i) the private placement units issued in a private placement sale by GigCapital5 prior to the Merger and (ii) the private placement units issued upon conversion of working capital notes issued by GigCapital5 (the “Working Capital Note Warrants”) prior to the Merger, which conversion occurred concurrent with the Merger (“Private Warrants”), are subject to treatment as a liability, as the transfer of the warrants to anyone other than the purchasers or their permitted transferees would result in these warrants having substantially the same terms as the warrants included in the public units that were issued by GigCapital5 prior to the Merger (“Public Warrants”). We determined that the fair value of each Private Warrant approximates the fair value of a Public Warrant. Accordingly, the Private Warrants are valued upon observable data and have been classified as Level 2 financial instruments.

Lynrock Lake Warrant

In connection with the Lynrock Lake Term Loan, we issued to Lynrock Lake a warrant to purchase 20,333,623 shares of common stock at an exercise price of $1.20 per share (the “Lynrock Lake Warrant”). Upon the closing of the October 2025 Private Placement, the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant and the per share exercise price were adjusted to 24,396,416 and $1.0002, respectively. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that we issue shares of common stock (or derivative securities) at a price that is either less than the $1.0002 exercise price or the fair market value of a share of common stock from the immediately prior trading day. The fair value of the Lynrock Warrant at issuance amounted to $16.5 million. On June 11, 2025, the Lynrock Lake Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. As equity classification is permitted for an instrument that requires net-cash settlement if the holders of the contract’s underlying

shares receive the same form of consideration in transactions outside our control, consequently the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheet upon modification. We determined the fair value of the Lynrock Lake Warrant using the Black-Scholes pricing model through the modification. Refer to Note 5 - Long-Term Debt and Note 8 - Stockholders’ Equity for more information.

Significant assumptions used in the valuation of the fair value of the Lynrock Lake Warrant as of issuance on February 26, 2025 and as of the modification on June 11, 2025 were as follows:

The Yorkville Warrant was exercisable until February 26, 2030. The fair value of the Yorkville Warrant at issuance amounted to $3.0 million. On June 11, 2025, the Yorkville Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. Consequently, upon modification, the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheets.

Paycheck Protection Program Loan

On February 24, 2021 and May 5, 2020, we received loans (“PPP Loans”) from US Bank in the amounts of $1.2 million (“Loan 1”) and $1.2 million (“Loan 2”), respectively, to fund payroll, rent and utilities through the Paycheck Protection Program (“PPP”). We repaid $19 thousand during the three months ended March 31, 2025 for Loan 1, which was due and repaid in full on May 5, 2025. As of December 31, 2025, the total principal outstanding under Loan 2 was $9 thousand, which was fully repaid on February 27, 2026. Interest expense for Loan 1 and Loan 2 for the three months ended March 31, 2026 and 2025 was immaterial.

Yorkville Pre-Paid Advance

On January 9, 2025, we and Yorkville entered into the Third Omnibus Amendment to the Yorkville Note, (the “Third Amendment”), pursuant to which, we and Yorkville agreed that for $1.5 million of the then current outstanding balance due under the Yorkville Note (principal and unpaid accrued interest), the fixed price for conversion will be modified to $1.752 per share, and for the remainder of the balance, the fixed price will not be changed but will remain $13.84185 per share as provided for in the Yorkville Note when we issued it on March 4, 2024. Further, the Third Amendment removed our obligation to make monthly payments to Yorkville, previously owing due to the occurrence of the Trigger Event, through the maturity date of the Yorkville Note of March 31, 2026. In exchange for this relief, the aggregate purchase price owed to us from the first Advance that occurs pursuant to the terms of the SEPA (the “Advance Proceeds”) will be paid by

Yorkville offsetting the amount of the Advance Proceeds against an equal amount outstanding under the Yorkville Note (first towards accrued and unpaid interest, and then towards outstanding principal and the corresponding payment premium in respect of such principal amount, if applicable), and that for any subsequent Advances pursuant to the terms of the SEPA, Yorkville will pay half of such Advance Proceeds directly to us and the other half of such Advance Proceeds will be paid by Yorkville offsetting the amount of the Advance Proceeds against an equal amount outstanding under the Yorkville Note (first towards accrued and unpaid interest, and then towards outstanding principal and the corresponding payment premium in respect of such principal amount, if applicable). On January 9, 2025, we delivered our first Advance Notice as defined under the SEPA for the sale of 295,000 shares of common stock. This resulted in the reduction of an additional $0.2 million in principal of the Yorkville Note.

On February 26, 2025, we and Yorkville entered into a Termination Agreement, pursuant to which the parties acknowledged the termination of the SEPA effective February 26, 2025. On February 26, 2025, we used a portion of the proceeds of the Lynrock Lake Term Loan to pay Yorkville an amount equal to $3.0 million in cash and issued to Yorkville the Yorkville Warrant to purchase 5,000,071 shares of our common stock at an exercise price of $1.20 per share to fully settle and discharge our obligations under the Yorkville Note and extinguish the Yorkville Note as having been fully performed. As a result of the extinguishment of the Yorkville Note, we recorded an expense of $1.9 million in other expense, net within the unaudited condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2025. The Yorkville Warrant was exercisable until February 26, 2030. The fair value of the Yorkville Warrant at issuance amounted to $3.0 million. On June 11, 2025, the Yorkville Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. Consequently, upon modification, the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheets. We determined the fair value of the Yorkville Warrant using the Black-Scholes Model through the modification. Refer to Note 3 - Fair Value Measurements for more information.

As of March 31, 2026 and December 31, 2025, there was no amount outstanding for the Yorkville Note. Interest expense, including amortization of debt issuance costs, for the three months ended March 31, 2025 was $0.5 million.

Cable Car Note

On January 9, 2025, we and Funicular Funds, LP (“Cable Car”) entered into an Omnibus Amendment (the “Cable Car Amendment”) to amend certain terms of the secured note purchase agreement by and between QT Imaging and Cable Car (the “Cable Car Note”), including a reduction of the conversion price for the Cable Car Note to $1.752 per share. Further, the Cable Car Amendment extended the maturity date for the Cable Car Note to March 31, 2026, in exchange for an extension fee (the “Extension Fee”) of $0.1 million to Cable Car, with such fee being added to the amount due and payable on such maturity date, unless the Cable Car Note is earlier converted pursuant to its terms, in which event the Extension Fee will also be converted. No interest will accrue or be due on the Extension Fee. Pursuant to the Cable Car Amendment, interest will accrue on the outstanding principal balance of the Cable Car Note at an annual rate equal to 6%, with interest being calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law. Interest will be due and payable on the maturity date for the Cable Car Note, unless the Cable Car Note is earlier converted pursuant to its terms, in which event such accrued and unpaid interest will also be converted. We recorded the Extension Fee of $0.1 million in other expense, net within the unaudited condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2025.

On February 26, 2025, we used a portion of the proceeds of the Lynrock Lake Term Loan to pay Cable Car an amount equal to the full principal, interest and fees amount of approximately $1.6 million in cash to fully settle and discharge our obligations under the Cable Car Note and extinguish the Cable Car Note as having been fully performed. As a result of the extinguishment of the Cable Car Note, we recorded an expense of $0.1 million in other expense, net within the unaudited condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2025.

As of March 31, 2026 and December 31, 2025, there was no amount outstanding for the Cable Car Note. Interest expense, including amortization of debt issuance costs, for the three months ended March 31, 2025 was $36 thousand.

Lynrock Lake Term Loan

On February 26, 2025, we entered into the Lynrock Lake Credit Agreement that provides the Lynrock Lake Term Loan with Lynrock Lake. The Lynrock Lake Credit Agreement is secured by a first priority lien on substantially all of our assets and provides for a term loan in the aggregate principal amount of $10.1 million at an interest rate of 10.0% per annum, compounded quarterly. Prior to the Second Amended Credit Agreement, the maturity date of the Lynrock Lake Credit Agreement was March 31, 2027 and is now March 31, 2029. The Lynrock Lake Term Loan will be repaid on the maturity date in an amount equal to the aggregate principal amount outstanding, together with all accrued and unpaid interest and any outstanding and payable fees.

Subject to the payment of the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), we may at any time prior to the maturity date optionally prepay the term loan, in full or in part, upon irrevocable written notice of three business days prior to the proposed prepayment; provided that if such prepayment is to be funded with the proceeds of a refinancing or disposition, such notice of prepayment may be revoked if the financing or disposition is not consummated; provided further, that any such prepayment made in connection with, or in anticipation of, a Change of Control (as defined in the Lynrock Lake Credit Agreement) will also be subject to a prepayment premium equal to 20% of the amount of principal being prepaid (the “Prepayment Premium”).

Subject to the payment of the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), at the option of Lynrock Lake, we will make mandatory repayments of the term loan upon the following occurrences:

• If on any date we or any of our subsidiaries will receive any cash proceeds from any Extraordinary Receipt (as defined in the Lynrock Lake Credit Agreement) in an amount equal to or exceeding $0.3 million in the aggregate, we will prepay the term loan within five business days of receipt of such cash proceeds, in an amount equal to 100% of the cash proceeds of such Extraordinary Receipt (as defined in the Lynrock Lake Credit Agreement);

• If any indebtedness will be incurred by us or any subsidiary thereof (excluding any indebtedness that the Lynrock Lake Credit Agreement permits us to incur), an amount equal to 100% of the net cash proceeds thereof will be applied on the date of incurrence or receipt toward the prepayment of the term loan;

• If on any date we or any of our subsidiaries will receive net cash proceeds in an amount equal to or exceeding (i) $0.3 million in any single transaction or series of related transactions or (ii) $0.3 million in the aggregate for all transactions during the term of the Lynrock Lake Credit Agreement from any Asset Sale (as defined in the Lynrock Lake Credit Agreement) or Recovery Event (as defined in the Lynrock Lake Credit Agreement) then we or such subsidiary will prepay the term loan, on or prior to the date which is five business days after the date of the realization or receipt by us or subsidiary in an amount equal to 100% of such proceeds; and

• Subject to the payment of the Prepayment Premium in addition to the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), in the event that a Change of Control (as defined in the Lynrock Lake Credit Agreement) will occur, we will prepay all of the outstanding term loan, on or prior to the date which is two business days after the date of such Change of Control (as defined in the Lynrock Lake Credit Agreement).

There are no requirements to make any prepayment in the event that we sell any of our capital stock. In addition, at the option of Lynrock Lake, we will also make mandatory repayments of the term loan on a monthly basis, no later than five business days after the end of each month (provided that such date for payment is prior to the maturity date), if we or our subsidiaries receive payment of accounts receivable on or after January 1, 2026, in an amount equal to 15% of the aggregate amount of payments of accounts receivable actually received during such prior month, net of any cost of collection incurred not in the ordinary course of business. No Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement) or Prepayment Premium is due or payable on any such mandatory prepayment as a result of receipt of accounts receivable on or after January 1, 2026. As of March 31, 2026, Lynrock Lake has not elected the repayment option in the amount equal to 15% of the aggregate amount of payments of accounts receivable actually received on or after January 1, 2026.

exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that we issue shares of common stock (or derivative securities) at a price that is either less than the $1.0002 exercise price or the fair market value of a share of common stock from the immediately prior trading day. The fair value of the Lynrock Lake Warrant at issuance amounted to $16.5 million. On June 11, 2025, the Lynrock Lake Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. As equity classification is permitted for an instrument that requires net-cash settlement if the holders of the contract’s underlying shares receive the same form of consideration in transactions outside our control, consequently the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheet upon modification. We determined the fair value of the Lynrock Lake Warrant using the Black-Scholes pricing model through the modification. Refer to Note 3 - Fair Value Measurements for more information.

Upon issuance of the Lynrock Lake Term Loan, we recorded a loss of $6.6 million, including debt issuance costs of $0.2 million, in other expense, net within the unaudited condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2025.

On August 26, 2025, we and Lynrock Lake entered into the First Amendment to the Lynrock Lake Credit Agreement (the “Lynrock Lake Amended Credit Agreement”) to add an additional tranche of $5.0 million (“Tranche B”) to the loan and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant. Tranche B was subject to the Tranche B Premium equal to 6% multiplied by the sum of (i) the principal of Tranche B being repaid plus (ii) all related accrued and unpaid interest. Subject to the payment of the Make-Whole Amount, if we received Net Cash Proceeds (as defined in the Lynrock Lake Credit Agreement) from any sale or issuance of our common stock, then we will, at the option of Lynrock Lake, prepay, or cause to be prepaid, Tranche B on or prior to the date which is thirty days after the date of the receipt by us of such Net Cash Proceeds in an amount equal to the lesser of (i) 100% of such Net Cash Proceeds or (ii) the principal amount of Tranche B on such date of prepayment, together with all accrued and unpaid interest thereon and any outstanding fees or premium, if any, payable in accordance with the Lynrock Lake Term Loan. Additionally, in connection with any mandatory prepayment of Tranche B on or prior to December 31, 2025, such mandatory prepayment will be subject to the payment of the Tranche B Premium instead of the Make-Whole Amount.

On October 6, 2025, we repaid the $5.0 million under Tranche B of the Lynrock Lake Term Loan, plus accrued interest and the Tranche B Premium, with a portion of the proceeds from the October 2025 Private Placement.

On May 12, 2026, we and Lynrock Lake entered into the Second Amended Credit Agreement to extend the maturity date of the Lynrock Lake Term Loan from March 31, 2027 to March 31, 2029, and to increase the interest rate from 10% to 12% per annum.

As of March 31, 2026, the outstanding amount of the Lynrock Lake Term Loan was $1.4 million, net of the unamortized debt discount of $8.7 million, and accrued interest was $1.2 million. Interest expense, including amortization of debt issuance costs, for the three months ended March 31, 2026 and 2025 was $1.0 million and $0.1 million, respectively.

On April 24, 2025, at the closing of the April 2025 Private Placement, we issued (i) 261,644 shares of common stock at a per share purchase price of $1.911, which represented 110% of the volume weighted trading price for the common stock on April 9, 2025; and (ii) warrants with a term of ten years from the initial exercise date to purchase up to an additional 523,286 shares of common stock with a per share exercise price of $2.16. The aggregate gross proceeds to us from the April 2025 Private Placement was approximately $0.5 million, before deducting the offering expenses payable by us, which expenses consisted solely of legal fees. We used the net proceeds from the offering for working capital purposes.

On May 12, 2025, we entered into the Second Securities Purchase Agreement” (the “May 2025 Private Placement”) in an amount of approximately $0.2 million, pursuant to which we issued 68,447 shares of common stock plus a PIPE Warrant to purchase 68,447 shares of common stock. The May 2025 Private Placement provides a per share purchase price of $2.922, which represents 110% of the five-day volume weighted trading price for the common stock through May 9, 2025, and the per share exercise price of the warrant is $3.36. We used the net proceeds from the offering for working capital purposes.

On September 30, 2025, we entered into the Third Securities Purchase Agreement, by and between us and certain accredited investors and qualified institutional buyers (the “October 2025 Private Placement”). At the closing of the October 2025 Private Placement on October 3, 2025, we issued (i) 2,232,243 shares of our common stock, par value $0.0001 per share; (ii) Subscription PIPE Warrants with a term of five years from the initial exercise date to purchase up to an additional 4,040,272 shares of common stock; and (iii) 5,424,083 pre‑funded PIPE Warrants to purchase up to an additional 1,808,055 shares of common stock, exercisable any time after its issuance (the “Pre-Funded Warrants”). The purchase price of each share of common stock was $4.50 and the purchase price for each Pre‑Funded Warrant was $4.4997. Both of these amounts were paid by the Purchasers at the closing of the October 2025 Private Placement. The aggregate gross proceeds to us from the October 2025 Private Placement was approximately $18.2 million, before deducting the offering expenses payable by us, which expenses consist solely of legal fees and the amounts provided for pursuant to a placement agency agreement The per share exercise price of each Subscription PIPE Warrant is $4.50 and the

per share exercise price of each Pre-Funded Warrant is $0.0003. We used the net proceeds from the offering for working capital purposes and to repay Tranche B of the Lynrock Lake Term Loan.

On January 22, 2026, we entered into the Fourth Securities Purchase Agreement where we received approximately $0.2 million from Dr. Avi Katz, the Chairman of our Board of Directors (the “January 2026 Private Placement”), in exchange for the issuance of (i) 24,107 shares of common stock at a per share purchase price of $6.43, which represented 110% of the 5-day volume weighted trading price for the common stock on January 22, 2026; and (ii) warrants with a term of ten years from the initial exercise date to purchase up to an additional 48,214 shares of common stock with a per share exercise price of $6.43. We used the net proceeds from the offering for working capital purposes.

As of March 31, 2026 and December 31, 2025, total PIPE Warrants, including the Pre-Funded Warrants, covering common stock of 7,946,588 shares and 7,898,374 shares were outstanding.

In connection with the Lynrock Lake Term Loan, on February 26, 2025, we issued to Lynrock Lake, pursuant to the terms of the Lynrock Lake Warrant, a warrant to purchase 20,333,623 shares of common stock at an exercise price of $1.20 per share. Upon the closing of the October 2025 Private Placement, the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant and the per share exercise price were adjusted to 24,396,416 and $1.0002, respectively. As of March 31, 2026 and December 31, 2025, the Lynrock Lake Warrant to purchase 24,396,416 shares of common stock was outstanding. Refer to Note 3 - Fair Value Measurements and Note 5 - Long-Term Debt for more information.

The determination of the fair value of options granted under the Inducement EIP and the 2024 EIP during the three months ended March 31, 2026 was computed using the Black-Scholes option pricing model with the following weighted-average assumptions:


	Three Months Ended March 31, 2026

Stock price per share	$	6.95
Expected option term (years)	5.8
Expected volatility	76.6		%
Risk-free rate of return	4.1		%
Expected annual dividend yield	—		%
Weighted-average grant date fair value	$	6.95

No options or RSUs were granted during the three months ended March 31, 2025.

Stock-based Compensation

The following table shows stock-based compensation expense by functional area in the condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2026 and 2025 (in thousands):


	Three Months Ended March 31,
	2026		2025
Research and development	$	30	$	17
Selling, general and administrative	351		84
Total stock-based compensation expense	$	381	$	101

Stock-based compensation expense capitalized to inventory for the three months ended March 31, 2026 and 2025 was insignificant.

As of March 31, 2026, the total unrecognized compensation cost related to all nonvested stock options and RSUs was $6.6 million and the weighted-average period over which it is expected to be recognized is 1.7 years.

10. Revenue

Revenue recognized during the three months ended March 31, 2026 and 2025 was as follows (in thousands):


	Three Months Ended March 31,
	2026		2025
Product	$	6,456	$	2,760
Service	74		38
Total revenue	$	6,530	$	2,798

Revenue recognized by geography during the three months ended March 31, 2026 and 2025 was as follows (in thousands):


	Three Months Ended March 31,
	2026		2025
United States	$	6,519	$	2,787
International	11		11
Total revenue	$	6,530	$	2,798

Substantially all of the revenue recognized by us during the three months ended March 31, 2026 and 2025 was recognized at a point in time. We had no contract assets as of March 31, 2026 and December 31, 2025. We had contract liabilities of $44 thousand as of March 31, 2026, all of which is expected to be recognized as revenue in the next twelve months. We had contract liabilities of $7 thousand as of December 31, 2025. Contract liabilities are included in accrued expenses and other current liabilities on the unaudited condensed consolidated balance sheets. Revenue recognized during the three months ended March 31, 2026 that was previously included in contract liabilities as of December 31, 2025 was $7 thousand.

One customer represented 10% or more of our accounts receivable balance and our total revenue as follows:


					Revenue
	Accounts Receivable				Three Months Ended March 31,
	March 31, 2026		December 31, 2025		2026		2025

Customer A	98	%	100	%	96	%	97	%

11. Income Taxes

Consistent with our conclusion as of December 31, 2025, we continue to believe that it is not more likely than not that the deferred tax assets will be realized and we therefore maintained a full valuation allowance against the deferred tax assets as of March 31, 2026. As a result, the estimated annual effective tax rate for 2026 is expected to be 0% because our forecasted losses are expected to generate no income tax benefit. Furthermore, there were no discrete tax items for the quarter ended March 31, 2026.

The income tax benefit was zero for both the three months ended March 31, 2026 and 2025.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law. Among its provisions, OBBBA introduced Section 174, which allows for the immediate expensing of domestic research and experimental expenditures, reversing the amortization requirement enacted under the Tax Cuts and Jobs Act of 2017. Taxpayers may elect to expense such costs either entirely in the year incurred or ratably over a two-year period. We will elect to expense over a two-year period. As we have historically been in a loss position, the election to deduct domestic research and experimental expenditures will not have any impact to our financial results for the year ending December 31, 2026.

12. Earnings (Loss) per Share

Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and potentially dilutive common share equivalents outstanding for the period determined using the treasury-stock and if-converted methods. For the purposes of the diluted net loss per share calculation, common stock equivalents are considered to be potentially dilutive securities.

Reconciliation of net loss per share for the three months ended March 31, 2026 and 2025 was as follows (in thousands, except per share data):


	Three Months Ended March 31,
	2026		2025


Net loss and comprehensive loss attributable to common stockholders	$	(3,406)	$	(11,136)
Weighted-average number of common shares used in computing net loss per share (1)	13,798		9,172
Net loss per share - basic and diluted (1)	$	(0.25)	$	(1.21)

The following securities were excluded from the calculation of net loss per share because the inclusion would be anti-dilutive as of March 31, 2026 and 2025 (in thousands):


	March 31, 2026	March 31, 2025
Common stock warrants (1)(2)	38,418	34,755
Merger earnout consideration shares (1)	1,000	2,000
Potential shares from convertible notes (1)	90	85

RSUs outstanding	839	—
Options outstanding (1)	1,101	652
Total	41,448	37,492

(1)Amounts as of March 31, 2025 differ from those published in prior unaudited condensed consolidated financial statements as they were retrospectively adjusted as a result of the Reverse Stock Split (refer to Note 1 - The Company and Summary of Significant Accounting Policies). Specifically, the number of potential common shares outstanding during the periods before the Reverse Stock Split are divided by the exchange ratio of 3:1, such that each three shares of potential common stock were combined and reconstituted into one share of potential common stock effective October 23, 2025.

(2)Warrants issuable for little or no cash consideration are considered outstanding common shares and included in the computation of basic net loss per share. As such, for the three months ended March 31, 2026, we included pre-funded common stock warrants in our computation of net loss per share and thus excluded them from the table above. These warrants were issued in October 2025 with an exercise price of $0.0003 per pre-funded warrant (See Note 8 – Stockholders’ Equity for additional information).

13. Related Party Transactions

Convertible Notes Payable

Our three convertible notes to three of our stockholders for advances up to $3.5 million in principal issued in July 2020 (the “2020 Notes”) bear annual interest of 5% on any amounts drawn.

The Sublessee will pay to us a rental fee for the Subleased Space as defined in the Sublease in an amount equal to $6 thousand through May 31, 2027. The term of the Sublease is one year unless terminated and will auto-renew on a month-to-month basis thereafter, unless otherwise terminated. The Sublease will expire automatically upon the termination of the Prime Lease, which is set to terminate in April 2027. We recorded sublease income of $18 thousand and $17 thousand in our unaudited condensed consolidated statements of operations and comprehensive loss for the three months ended March 31, 2026 and 2025, respectively.

Overview

We are a medical device company founded in 2012 and engaged in the research, development, and commercialization of innovative body imaging systems using low energy sound. We believe that medical imaging is critical to the detection, diagnosis, and treatment of disease and that it should be safe, affordable, and accessible. Our goal is to improve global health outcomes through the development and commercialization of imaging devices that address critical healthcare challenges with accuracy and precision.

With the support of nearly $18.0 million in financial support from the U.S. National Institutes of Health (“NIH”), we developed a novel, comprehensive body imaging technology that has high resolution, high sensitivity, high specificity, high positive and negative predictive values, and is safe and inexpensive. The technology is based on ultra-low frequency transmitted sound and uses a one-of-a-kind novel sound back-scatter design and inverse-scattering reconstruction to create its images.

Our current Breast Acoustic CT Scanner is a Class II device subject to premarket notification and clearance under Section 510(k) of the Federal Food, Drug, and Cosmetic Act (“FDCA”). On August 23, 2016, we submitted a Section 510(K) Summary of Safety and Effectiveness application for the Breast Acoustic CT Scanner in accordance with 21 CFR 807.92 under 510(K) Number K162372. As part of meeting the general requirements for basic safety and essential performance of the Breast Acoustic CT Scanner (formerly, QT Ultrasound Breast Scanner) pursuant to AAMI ES60601-1:2005/(R)2012 and A1:2012 Medical electrical equipment, testing was conducted by Intertek, an independent testing laboratory, located in Menlo Park, CA. Intertek also conducted applicable testing pursuant to IEC 60601-1-6 Edition 3.1 2013-10-Medical electrical equipment Part 1-6 General requirements for safety - Collateral Standard: Usability. In addition, we conducted, and Intertek witnessed, all applicable testing pertaining to the requirements for the safety of ultrasonic medical diagnostic and monitoring equipment and to demonstrate compliance with the Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment. This test on acoustic output was pursuant to IEC 60601-2-37 Edition 2.0.2007 Medical electrical equipment - Part 2-37: Particular requirements for the basic safety and essential performance of ultrasonic medical diagnostic and monitoring equipment. Finally, system verification testing was conducted to ensure that the Breast Acoustic CT Scanner met all design and other requirements including but not limited to that no new issues of safety or effectiveness compared to the predicate device, SoftVue System manufactured by Delphinus Medical Technologies, were raised.

Since our inception, we have devoted substantially all our financial resources to acquiring and developing the base technology for our body imaging systems, conducting research and development activities, securing related intellectual property rights, and for managing corporate operations and growth. On June 6, 2017, the FDA, in response to QT Imaging’s Section 510(K) Summary of Safety and Effectiveness premarket notification, determined that the Breast Acoustic CT Scanner is substantially equivalent to the predicate device. Our use of the words “safe,” “safety,” “effectiveness,” and “efficacy” in relation to the Breast Acoustic CT Scanner in this Management's Discussion and Analysis and all other documents related to us is limited to the context of the Section 510(K) Summary of Safety and Effectiveness that was reviewed and responded to by the FDA.

Our strategies for commercializing the Breast Acoustic CT Scanner include the following:

•Create disruptive technological innovation (software, artificial intelligence, and smart physics) to improve medical imaging and thus health care quality and access;

•Continue to improve our high quality, high resolution, native 3D, reproducible image quality regardless of operator or breast size/tissue type breast imaging technology, as well as the techniques for quantifiable analysis, comparison, and training;

•Partner with strategic business and distribution channels to address the U.S. market for breast imaging immediately and, other regions in the future, to place the Breast Acoustic CT Scanner in hospitals, radiology centers, etc. and generate awareness of the benefits of our technology;

•Perform manufacturing internally to us and partner strategically for large scale manufacturing;

•Expand the market by supporting additional Direct-to-Customer and Direct-to-Patient approaches to enable the ability to lower health care costs and increase access via personal medical imaging;

•Provide a new social and economic opportunity for consumers to take control of some aspects of their own health care—such as imaging for minor injuries or medical conditions without needing a healthcare “gate-keeper;” and

•Focus our intellectual capabilities and ethical framework to become unified in our mission to improve the quality and lower the cost of health care world-wide . . . “It’s about time.”

We have incurred net operating losses and negative cash flows from operations since our inception and had an accumulated deficit of $56.4 million as of March 31, 2026. During the three months ended March 31, 2026, we incurred a net loss of $3.4 million and used $3.7 million of cash in operating activities. We continue to incur losses, and our ability to achieve and sustain profitability will depend on the achievement of sufficient revenue to support our cost structure. We may never achieve profitability and, unless and until we do, we will need to continue to raise additional capital.

We expect to incur additional recurring administrative expenses associated as a publicly traded company, including costs associated with compliance under the Exchange Act, annual and quarterly reports to stockholders, transfer agent fees, audit fees, incremental director and officer liability insurance costs, Sarbanes-Oxley Act compliance readiness, and director and officer compensation.

Recent Developments

On January 19, 2026, we entered into the Al Naghi Distribution Agreement for an initial term of three years. Under the terms of the Al Naghi Distribution Agreement, we granted to Al Naghi the exclusive right to market, advertise, and sell our Breast Acoustic CT Scanner and the QTI Cloud SaaS platform subscriptions in the UAE, with MOQs of 7 scanners in 2026, 16 scanners in 2027, and 20 scanners in 2028, for a total minimum of 43 scanners, representing revenue of more than $24 million in 2026 through 2028, upon regulatory approval from the EDE in the UAE, which was received on March 17, 2026.

On January 22, 2026, we entered into the Fourth Securities Purchase Agreement where we received approximately $0.2 million from Dr. Avi Katz, the Chairman of our Board of Directors, in exchange for the issuance of (i) 24,107 shares of common stock at a per share purchase price of $6.43, which represented 110% of the 5-day volume weighted trading price for the common stock on January 22, 2026; and (ii) warrants with a term of ten years from the initial exercise date to purchase up to an additional 48,214 shares of common stock with a per share exercise price of $6.43. We used the net proceeds from the offering for working capital purposes.

Effective January 28, 2026, upon meeting all of the Nasdaq listing requirements, our common stock was uplisted from the OTCQB Venture Market to the Nasdaq Capital Market and began trading under the ticker symbol “QTI.”

Service revenue is recognized at the time the related performance obligation is satisfied, in an amount that reflects the consideration that we expect to receive in exchange for those services.

Cost of revenue consists of our product costs, which includes manufacturing costs, payroll and payroll related costs, stock-based compensation expenses, duties and other applicable importing costs, shipping and handling costs, packaging costs, warranty replacement costs, fulfillment costs, inventory obsolescence and write-offs, and direct or allocated expenses for rent, maintenance of facilities, insurance, and other overhead. We expect our cost of revenue to increase in absolute dollars and decrease as a percentage of revenue over time as we shift to new manufacturing processes and vendors that we anticipate will result in greater efficiency and lower per unit costs.

We expect we will continue to invest additional resources into our products to expand and further develop our offerings. The level and timing of investment in these areas could affect our cost of revenue in the future.

Operating Expenses

Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with the research and development of our products, which include payroll and payroll related costs, stock-based compensation expenses, consultant costs, professional services costs, material and supplies costs, clinical study costs, and direct or allocated expenses for rent, maintenance of facilities, insurance, and other overhead.

We expense all research and development costs in the periods in which such costs are incurred. Research and development activities are central to our business. We expect that our research and development expenses will increase substantially for the foreseeable future as we continue to invest in the continued development of the Breast Acoustic CT Scanner.

We cannot reasonably determine the nature, timing and costs of the efforts that will be necessary to build our QTI Cloud SaaS platform, run clinical trials that are necessary to generate biomarker data, and reduce the bill of materials and other

costs to manufacture the Breast Acoustic CT Scanner. Our research and development expenses may vary significantly based on factors such as, without limitation:

•The timing and progress of development activities;

•Our ability to maintain our current research and development programs and to establish new ones;

•The receipt of regulatory approvals from applicable regulatory authorities without the need for independent clinical trials or validation;

•Duration of subject participation in any trials and follow-ups;

•The countries and jurisdictions in which the trials are conducted;

•Length of time required to enroll eligible subjects and initiate trials;

•Per trial subject costs;

•Number of trials required for regulatory approval;

•The timing, receipt, and terms of any marketing approvals from applicable regulatory authorities;

•The success of our distribution arrangements, and our ability to establish new licensing or collaboration arrangements outside of U.S.;

•The hiring and retention of research and development personnel;

•Obtaining, maintaining, defending, and enforcing intellectual property rights; and

•The phases of development of our product candidates.

Any changes in the outcome of any of these variables with respect to the development of our products or product candidates could significantly change the costs and timing associated with the development of these products and product candidates.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of payroll and payroll related costs, stock-based compensation expenses, consultant costs, professional services costs, which include legal, investor relations, intellectual property, audit, accounting, and tax services, marketing costs, and direct or allocated expenses for rent, maintenance of facilities, insurance, and other overhead.

We anticipate that our selling, general and administrative expenses will increase to support our expanding headcount and operations, increased costs of operating as a public company, the development of a commercial infrastructure to support commercialization of our products and product candidates, increased support for existing and new distribution partner relationships, and the use of outside service providers such as insurers, consultants, lawyers, and accountants. We also expect selling expenses to increase in the near term as we promote our brand through marketing and advertising initiatives, expand market presence, and hire additional personnel to drive penetration and generate leads.

Revenue

Revenue increased by $3.7 million to $6.5 million during the three months ended March 31, 2026 from $2.8 million during the three months ended March 31, 2025. The increase was primarily due to the sale of 13 Breast Acoustic CT Scanners during the three months ended March 31, 2026, as compared with six scanners sold during the three months ended March 31, 2025, in accordance with MOQs per the Amended NXC Distribution Agreement.

Cost of Revenue

Cost of revenue increased by $2.9 million to $3.9 million during the three months ended March 31, 2026 from $1.0 million during the three months ended March 31, 2025. The increase was primarily due to the sale of 13 Breast Acoustic CT Scanners during the three months ended March 31, 2026, as compared with six scanners sold during the three months ended March 31, 2025, including one scanner that had been repurchased at a lower cost and one depreciated scanner that had been repurposed for sale.

Operating Expenses

Research and Development Expenses

Research and development expenses increased by $0.9 million to $1.7 million during the three months ended March 31, 2026 from $0.9 million during the three months ended March 31, 2025. The increase was primarily due to an increase in professional service costs of $0.6 million and an increase in payroll and payroll-related expenses of $0.2 million due to higher headcount.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased by $1.3 million to $3.3 million during the three months ended March 31, 2026 from $2.0 million during the three months ended March 31, 2025. The increase was primarily due to an increase in payroll and payroll-related expenses of $1.1 million due to higher headcount and an increase in professional services costs of $0.2 million, partially offset by an increase in the allocation of overhead of $0.3 million from selling, general and administrative expenses to cost of revenue.

Interest expense, net

Interest expense, net increased by $0.2 million to $0.9 million during the three months ended March 31, 2026 from $0.7 million during the three months ended March 31, 2025. The increase was primarily due to the increase in accrued interest and debt discount amortization of $0.9 million for the Lynrock Lake Term Loan, partially offset by the decrease in Yorkville Note interest of $0.5 million as a result of the termination of the Yorkville Note in the first quarter of 2025 and an increase in interest income of $0.1 million.

Other expense, net

Other expense, net decreased by $8.7 million to $4 thousand during the three months ended March 31, 2026 from $8.7 million during the three months ended March 31, 2025. The decrease was primarily due to $6.6 million in noncash expense incurred at the issuance of the Lynrock Lake Term Loan, and $2.2 million due to an extinguishment loss and modification charges for the Yorkville Note and Cable Car Note during the three months ended March 31, 2025.

Change in fair value of warrant liability

Change in fair value of warrant liability changed by $0.5 million to expense of $0.2 million during the three months ended March 31, 2026 from expense of $0.7 million during the three months ended March 31, 2025. The change was primarily due to the decrease in the Lynrock Lake Warrant liability of $0.4 million and $0.1 million of expense from the modification on the Yorkville Warrant during the three months ended March 31, 2025.

Change in fair value of derivative liability

Change in the fair value of derivative liability changed by $0.1 million to nil for during three months ended March 31, 2026 from income of $0.1 million during the three months ended March 31, 2025. The change was due to the extinguishment of the derivative liability during the three months ended March 31, 2025 as a result of the extinguishment of the Yorkville Note.

Change in fair value of earnout liability

Change in the fair value of earnout liability changed by $0.1 million to income of $50 thousand during the three months ended March 31, 2026 from expense of $50 thousand during the three months ended March 31, 2025. The change was primarily due to changes in the probability of outcome related to our revenue assumptions.

Liquidity and Capital Resources

Sources of Liquidity

Liquidity describes our ability to meet financial obligations which arise during the normal course of business. To date, we have financed our operations primarily through the sale of equity securities, issuances of convertible notes and other debt, and grants from the U.S. government. We expect to derive future liquidity primarily through our revenue from customers and sale of equity securities. Our current liquidity position consists of cash on hand and certificates of deposit.

As of March 31, 2026, we had cash and cash equivalents of $7.0 million. We have incurred net operating losses and negative cash flows from operations since our inception and had an accumulated deficit of $56.4 million as of March 31, 2026. During the three months ended March 31, 2026, we incurred a net loss of $3.4 million and used $3.7 million of cash in operating activities. We expect to continue to incur losses, and our ability to achieve and sustain profitability will depend on the achievement of sufficient revenue to support our cost structure. We may never achieve profitability and, unless and until we do, we will need to continue to raise additional capital.

On February 26, 2025, we entered into the Lynrock Lake Credit Agreement that provided the Lynrock Lake Term Loan in the aggregate principal amount of $10.1 million. On August 26, 2025, we and Lynrock Lake entered into the Lynrock Lake Amended Credit Agreement to add Tranche B in the amount of $5.0 million to the Lynrock Lake Term Loan and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant. On October 6, 2025, we repaid the $5.0 million under Tranche B of the Lynrock Lake Term Loan, plus accrued interest and the Tranche B Premium. On May 12, 2026, we and Lynrock Lake entered into the Second Amended Credit Agreement to extend the maturity date of the Lynrock Lake Term Loan from March 31, 2027 to March 31, 2029, and to increase the interest rate from 10% to 12% per annum.

During the year ended December 31, 2025 and the three months ended March 31, 2026, we completed a series of PIPE transactions, where we received cash in exchange for the issuance of shares of common stock plus warrants for the purchase of common stock.

•On April 24, 2025, we entered into the First Securities Purchase Agreement in an amount of approximately $0.5 million from related persons. We used the net proceeds from the offering for working capital purposes.

•On May 12, 2025, we entered into the Second Securities Purchase Agreement in an amount of approximately $0.2 million. We used the net proceeds from the offering for working capital purposes.

•On October 3, 2025, we entered into the Third Securities Purchase Agreement in an amount of approximately $18.2 million, before deducting the offering expenses payable by us. We used the net proceeds from the offering for working capital purposes and to repay Tranche B of the Lynrock Lake Term Loan.

•On January 22, 2026, we entered into the Fourth Securities Purchase Agreement in an amount of approximately $0.2 million from a related person. We used the net proceeds from the offering for working capital purposes.

During the years ended December 31, 2025 and 2024 and the three months ended March 31, 2026, we entered into several distribution agreements which provided us with MOQs as follows:

•On June 18, 2024, as amended on December 11, 2024 and further amended on March 28, 2025, we entered into the Amended NXC Distribution Agreement, which provides us with MOQs of 60 scanners in 2026, representing revenue of more than $28 million in 2026.

•On August 21, 2025, we entered into the Gulf Medical Distribution Agreement for an initial term of three years. Under the terms of the Gulf Medical Distribution Agreement, we granted to GMC the exclusive right to market, advertise, and sell our Breast Acoustic CT Scanner and the QTI Cloud SaaS platform subscriptions in Saudi Arabia, with MOQs of 20 scanners in 2026, 32 scanners in 2027, and 40 scanners in 2028, for a total minimum of 92 scanners, representing revenue of more than $51 million in 2026 through 2028, upon regulatory approval from the SFDA in Saudi Arabia.

•On January 19, 2026, we entered into the Al Naghi Distribution Agreement for an initial term of three years. Under the terms of the Al Naghi Distribution Agreement, we granted to Al Naghi the exclusive right to market, advertise, and sell our Breast Acoustic CT Scanner and the QTI Cloud SaaS platform subscriptions in the UAE, with MOQs of 7 scanners in 2026, 16 scanners in 2027, and 20 scanners in 2028, for a total minimum of 43 scanners, representing revenue of more than $24 million in 2026 through 2028, upon regulatory approval from the EDE in the UAE, which was received on March 17, 2026.

Currently, as a result of the armed conflicts and heightened geopolitical tensions in the Middle East, including ongoing U.S. and Israeli military operations against Iran launched on February 28, 2026, we are unable to ship scanners to GMC and Al Naghi. If we are unable to ship scanners to our distributors in the Gulf Region for a prolonged period of time, our business, financial condition, results of operations, and liquidity could be materially impacted.

Lynrock Lake Term Loan

In connection with the Lynrock Lake Term Loan, we issued to Lynrock Lake the Lynrock Lake Warrant to purchase 20,333,623 shares of common stock at an exercise price of $1.20 per share. Upon the closing of the October 2025 Private Placement, the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant and the per share exercise price were adjusted to 24,396,416 and $1.0002, respectively. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that we issue shares of common stock (or derivative securities) at a price that is either less than the $1.0002 exercise price or the fair market value of a share

of common stock from the immediately prior trading day. The fair value of the Lynrock Lake Warrant at issuance amounted to $16.5 million. On June 11, 2025, the Lynrock Lake Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. As equity classification is permitted for an instrument that requires net-cash settlement if the holders of the contract’s underlying shares receive the same form of consideration in transactions outside our control, consequently the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheet upon modification. We determined the fair value of the Lynrock Lake Warrant using the Black-Scholes pricing model through the modification.

On August 26, 2025, we and Lynrock Lake entered into the Lynrock Lake Amended Credit Agreement to add Tranche B in the amount of $5.0 million to the loan and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant. Tranche B was subject to the Tranche B Premium equal to 6% multiplied by the sum of (i) the principal of Tranche B being repaid plus (ii) all related accrued and unpaid interest. Subject to the payment of the Make-Whole Amount, if we received Net Cash Proceeds (as defined in the Lynrock Lake Credit Agreement) from any sale or issuance of our common stock, then we will, at the option of Lynrock Lake, prepay, or cause to be prepaid, Tranche B on or prior to the date which is thirty days after the date of the receipt by us of such Net Cash Proceeds in an amount equal to the lesser of (i) 100% of such Net Cash Proceeds or (ii) the principal amount of Tranche B on such date of prepayment, together with all accrued and unpaid interest thereon and any outstanding fees or premium, if any, payable in accordance with the Lynrock Lake Term Loan. Additionally, in connection with any mandatory prepayment of Tranche B on or prior to December 31, 2025, such mandatory prepayment will be subject to the payment of the Tranche B Premium instead of the Make-Whole Amount.

Related Party Convertible Notes Payable

Our 2020 Notes bear annual interest of 5% on any amounts drawn. The additional note issued in March 2022 as part of the 2020 Notes, has an annual interest rate of 8%. All principal and interest payments were initially due on or before July 1, 2025. In connection with the issuance of the Lynrock Lake Term Loan, on February 26, 2025, the maturity date on these convertible notes payable was extended to October 21, 2027.

The 2020 Notes are convertible, at the holder’s option, into shares of our common stock at the lower of $43.77 per share or the offering price in a financing of at least $5.0 million in equity from unaffiliated parties. As of March 31, 2026, an aggregate of 90,385 shares of common stock would be issued if the entire principal and interest under the 2020 Notes was converted.

As of March 31, 2026 and December 31, 2025, the outstanding amount of the 2020 Notes was $3.9 million, and accrued interest was $0.8 million and $0.7 million, respectively.

Related Party Working Capital Loan

On May 3, 2023, we issued the Working Capital Note to a stockholder for a principal amount of $0.3 million. The Working Capital Note was subsequently amended and restated six times on June 12, 2023 to add an additional principal amount of $0.1 million, August 15, 2023 to add an additional principal amount of $0.1 million, August 29, 2023 to add an additional principal amount of $0.1 million, September 12, 2023 to add an additional principal amount of $0.1 million, September 15, 2023 to add an additional principal amount of $0.1 million, and October 26, 2023 to add an additional principal amount of $0.1 million, for an aggregate principal amount outstanding as of March 31, 2026 and December 31, 2025 under the Working Capital Note of $0.7 million. The Working Capital Note was issued to provide us with additional working capital

during the period prior to consummation of the Business Combination Agreement with GigCapital5. The Working Capital Note is interest-free and originally matured on the earlier of (i) the date on which we consummated the Business Combination with GigCapital5; (ii) the date we wind up; or (iii) December 31, 2023. The Working Capital Note may be prepaid without penalty. On March 4, 2024, the holder of the Working Capital Note agreed to extend and subordinate the promissory note pursuant to and in accordance with the terms of the Business Combination Agreement. Effective on the closing of the Business Combination, the Working Capital Note cannot be repaid prior to the repayment or conversion of the Yorkville Note received from Yorkville. In connection with the issuance of the Lynrock Lake Term Loan, on February 26, 2025, the maturity date on the Working Capital Note was extended to October 1, 2027.

Cash Flows

The following table provides information regarding our cash flows for the periods presented (in thousands):

Net increase in cash and cash equivalents and restricted cash and cash equivalents	$	(3,512)	$	1,816

Net Cash Used In Operating Activities

Net cash used in operating activities was $3.7 million for the three months ended March 31, 2026 as compared to $3.5 million for the three months ended March 31, 2025. Net cash used for the three months ended March 31, 2026 consisted of a net loss of $3.4 million, adjusted for non-cash expenses primarily including stock-based compensation expense of $0.4 million, non-cash interest of $0.7 million, and change in fair value of warrant liability of $0.2 million, and adjusted for the net change in operating assets and liabilities primarily including an increase in accounts receivable of $0.6 million, an increase in inventory of $1.8 million, an increase in prepaid expenses and other current assets of $0.2 million, and a decrease in accounts payable of $0.5 million, partially offset by an increase in other liabilities of $1.2 million and an increase in accrued expenses and other current liabilities of $0.5 million.

Net cash used for the three months ended March 31, 2025 consisted of a net loss of $11.1 million, adjusted for non-cash expenses primarily including loss on issuance of the Lynrock Lake Term Loan of $6.6 million, debt extinguishment loss of $2.0 million, non-cash interest of $0.5 million, and change in fair value of warrant liability of $0.7 million, and adjusted for the net change in operating assets and liabilities primarily including an increase in accounts receivable of $2.7 million and an increase in prepaid expenses and other current assets of $0.6 million, partially offset by a decrease in inventory of $0.3 million, and an increase in accrued expenses and other liabilities of $0.5 million.

Net Cash Used in Investing Activities

Net cash used in investing activities was $17 thousand for the three months ended March 31, 2026 due to purchases of property and equipment. There were no investing activities for the three months ended March 31, 2025.

Net Cash Provided by Financing Activities

During the three months ended March 31, 2026, net cash provided by financing activities was $0.2 million primarily due to net proceeds from the sale of common stock and warrants of $0.2 million, and proceeds from stock option exercises of $0.2 million, partially offset by $0.2 million of stock issuance costs accrued in 2025 but paid during the three months ended March 31, 2026.

During the three months ended March 31, 2025, net cash provided by financing activities was $5.4 million, primarily due to $10.0 million of net proceeds received from issuance of long-term debt related to the Lynrock Lake Term Loan, partially offset by the repayment of long-term debt of $4.6 million related to the Yorkville Note, Cable Car Note, and the PPP Loans.

Future Funding Requirements

We expect to incur increased significant expenses in connection with our ongoing activities, particularly as we continue the research and development of our products and product candidates, seek expanded regulatory clearances for the Breast Acoustic CT Scanner, expand our clinical studies, and build a U.S. sales and marketing team. We expect to incur additional

costs associated with operating as a public company. Our future funding requirements, both short-and long-term, will depend on many factors, including, without limitation:

•Having the cash to repay our debt obligations as they come due;

•Expand our current manufacturing operations and expand existing and build new partnerships with contract manufacturing third-party vendors;

•Purchase inventory for our planned shipments;

•Expand or enhance our distribution with third-party distribution channels outside of the U.S.;

•The progress and results of our trials and interpretation of those results by the FDA (and other regulatory authorities, as required);

•Seek regulatory clearances for product candidates and expanded regulatory clearance for the Breast Acoustic CT Scanner;

•The cost of operating as a public company, including hiring additional personnel as well as increased director and officer insurance premiums, audit and legal fees, investor relations fees and expenses related to compliance with public company reporting requirements under the Exchange Act and rules implemented by the SEC and Nasdaq; and

•The costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights, and defending our intellectual property-related claims.

We plan to continue to incur substantial costs in order to conduct research and development activities and to invest in the continued development of the Breast Acoustic CT Scanner. Additional capital will be needed to undertake these activities and commercialization efforts. We intend to raise such capital through the issuance of additional equity, borrowings, and potential strategic alliances with other companies. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends. If such financing is not available at adequate levels or on acceptable terms, we could be required to significantly reduce operating expenses and delay, reduce the scope of or eliminate some of our development programs or our commercialization efforts, out-license intellectual property rights to our product candidates, and sell unsecured assets, or a combination of the foregoing, any of which may have a material adverse effect on our business, results of operations, financial condition and/or our ability to fund our scheduled obligations on a timely basis, or at all.

Because of the numerous risks and uncertainties associated with manufacturing, research, development and commercialization of products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on, and could increase significantly as a result of, many factors, including, without limitation:

•The timing, receipt, and amount of revenue from the sales of the Breast Acoustic CT Scanner and related products and services, or any future approved or cleared products and product candidates, if any;

•The cost of future activities, including product sales, medical affairs, marketing, manufacturing, and distribution for the Breast Acoustic CT Scanner;

•The costs, timing, and outcomes of regulatory review of applications for expanded clearances for the Breast Acoustic CT Scanner;

•The scope, progress, results, and costs of researching, developing and manufacturing our product candidates or any future product candidates, and conducting studies and clinical trials;

•The timing of, and the costs involved in, obtaining regulatory approvals or clearances for our product candidates or any future product candidates;

•The cost of manufacturing our product candidates or any future product candidates and any products we successfully commercialize, including costs associated with building out our manufacturing capabilities;

•The cost and time needed to attract and retain skilled personnel to support our continued growth;

•Our ability to establish and maintain strategic collaborations, licensing, or other arrangements and the financial terms of any such agreements that we may enter into; and

•The costs associated with being a public company.

Additionally, our operating plans may change, and we may need additional funds to meet operational needs and capital requirements for future trials and other research and development activities. Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic partnerships or marketing, distribution, or licensing arrangements with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect the rights of our stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures, or declaring dividends. In addition, debt financing would result in increased fixed payment obligations.

If we raise funds through collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or products, or grant licenses on terms that may not be favorable to us.

If we are unable to raise additional funds when needed, we may be required to delay, reduce, or eliminate our product development or future commercialization efforts, or grant rights to develop and market products that we would otherwise prefer to develop and market ourselves.

Our ability to continue as a going concern is dependent upon our ability to successfully accomplish these plans and secure sources of financing and attain profitable operations. If we are unable to obtain adequate capital, we could be forced to cease operations. See the section entitled Risk Factors for additional factors and risks associated with our capital requirements.

Off-Balance Sheet Arrangements

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements.

Contractual Obligations

We lease our operating facilities in Novato, California, under a non-cancelable operating lease through May 31, 2027. There are no options or rights to extend the term of this lease.

Contingencies

Litigation

We are subject to occasional lawsuits, investigations and claims arising out of the normal course of business. As of the date the unaudited condensed consolidated financial statements were available to be issued, management is not aware of any pending claims that will have a material impact on our unaudited condensed consolidated financial statements.

Emerging Growth Company

We are an emerging growth company (“EGC”), as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company, or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our unaudited condensed consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

In addition, we intend to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an EGC, we intend to rely on such exemptions, we are not required to, among other things: (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd- Frank Wall Street Reform and Consumer Protection

Act; (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board (United States) regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis); and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer’s compensation to median employee compensation.

We will remain an EGC under the JOBS Act until the earliest of (i) the last day of our first fiscal year following the fifth anniversary of the Closing of the Business Combination, (ii) the last date of our fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the date on which we are deemed to be a “large accelerated filer,” as defined in Rule 12b-2 promulgated under the Exchange Act, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three-years.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Based on an evaluation under the supervision and with the participation of our management, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of March 31, 2026 to provide reasonable assurance that information required to be disclosed by us in reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Inherent Limitations on Effectiveness of Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute 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 its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot provide assurance that such improvements will be sufficient to provide us with effective internal control over financial reporting.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended March 31, 2026 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Part II

Item 1: Legal Proceedings

We are not currently subject to any material legal proceedings, nor, to our knowledge, is any material legal proceeding threatened against us or any of our officers or directors in their corporate capacity.

Item 1A: Risk Factors

The statements in this section describe the known material risks to our business and should be considered carefully. As of March 31, 2026, there have been no material changes in risk factors previously disclosed in our Annual Report, other than as noted below. Any of these risk factors disclosed in our Annual Report or herein could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

The forward-looking statements contained in this Quarterly Report are based on our current expectations and beliefs concerning future developments and their potential effects on us. Future developments affecting us may not be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, the following risks, uncertainties and other factors:

We are a development-stage company with limited operating history and significant losses since inception which may make it difficult to evaluate prospects for our future viability and predict our future performance. We may never be able to effectuate our business plan or achieve any meaningful revenue or reach profitability.

We have a limited operating history and only a preliminary and unproven business plan upon which investors may evaluate our prospects. We have demonstrated the commercial viability of our breast imaging platform at scales of tens of scanners but not yet demonstrated the commercial viability on larger scales. The QT Breast Scanner is deployed at facilities in the United States and abroad. Even if we are able to do so, we may not be able to manufacture the QT Breast Scanner device at the costs needed to support our business model. Even if we are able to commercialize some of our products or product candidates, there can be no assurance that we will generate significant revenues or ever achieve profitability. We expect to continue to incur significant sales and marketing, research and development, regulatory and other expenses as we expand our marketing efforts to increase adoption of our products, expand existing relationships, obtain regulatory approvals for our product candidates, conduct clinical studies on our existing and planned product candidates and develop new product candidates or add new features to our existing products. There is no assurance that our distribution partners will succeed in selling and servicing devices in sufficient volumes to help the company meet its business plan, revenue objectives or profitability.

Furthermore, even if our technology and product become commercially viable and deployed at scale, we may not generate sufficient revenue necessary to support our business. We may never successfully stimulate market interest in our QT Breast Scanner in the near-to-mid-term at any level or at all, which may cause our business to fail. The medical imaging industry is also highly competitive, and our technology, products, services or business models may not achieve widespread market acceptance. If we are unable to address any issues mentioned above, or encounter other problems, expenses, difficulties, complications, and delays in connection with the starting and expansion of our business, our entire business may fail, in which case you may lose your entire investment.

We have a history of net losses and negative cash flow from operations since inception and we expect such losses and negative cash flows from operations to continue in the foreseeable future. As of March 31, 2026 and December 31, 2025, we had an accumulated deficit of approximately $56.4 million and $53.0 million, respectively. For the three months ended March 31, 2026 and 2025, we incurred net losses attributable to the Company of approximately $3.4 million and $11.1 million, respectively. For the three months ended March 31, 2026 and 2025, we used cash in operations of $3.7 million and $3.5 million, respectively. We anticipate our losses will continue to increase from current levels because we expect to incur additional costs related to developing our business, including research and development costs, manufacturing costs, employee-related costs, costs of complying with government regulations, intellectual property development and prosecution costs, marketing and promotion costs, capital expenditures, general and administrative expenses, and costs associated with operating as a public company.

Our ability to generate revenue from our operations and ultimately achieve profitability will depend on factors including but not limited to whether we can complete the development and commercialization of our QT Breast Scanner breast imaging technology and our future products, whether we can manufacture the QT Breast Scanner and future products on a commercial scale in such amounts and at such costs as we anticipate, and whether we can achieve market acceptance of our products, services and business models. The net losses that we incur may fluctuate significantly from period to period. As a result of these increased expenditures, we will need to generate significant additional revenue in order to offset our operating expenses and achieve and sustain profitability. Accordingly, we may not achieve or maintain profitability, and we may continue to incur significant losses in the future. Even if we achieve profitability, we cannot be sure that we will remain profitable for any substantial period of time. If we do not achieve or sustain profitability, it will be more difficult for us to finance our business and accomplish our strategic objectives, either of which would have a material adverse effect on our business, financial condition, results of operations and prospects and may cause the market price of the common stock to decline.

Future sales, or the perception of future sales, of common stock by us or our existing stockholders in the public market could cause the market price for our common stock to decline.

The sale of substantial amounts of shares of common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

All shares issued as merger consideration in the Business Combination are freely tradable without registration under the Securities Act and without restriction by persons other than our “affiliates” (as defined under Rule 144), including our directors, executive officers and other affiliates, and certain other former QT Imaging stockholders.

The Company has registered in a resale registration statement on Form S-1 declared effective by the SEC on May 22, 2024, securities held by certain stockholders of the Company which have the right, subject to certain conditions, to require us to register the sale of their shares of common stock under the Securities Act, pursuant to the terms of a registration statement that we entered into with GigAcquisitions5 and certain other security holders of GigCapital5 and QT Imaging (the “GigCapital5 Registration Rights Agreement”). The Company has also registered in a resale registration statement on Form S-1 declared effective by the SEC on February 5, 2025, the securities sold in the private placement conducted in November 2024 as the purchasers received the right, subject to certain conditions, to require us to register the sale of their shares of common stock under the Securities Act, pursuant to the terms of a registration statement that we entered into (“PIPE Registration Rights Agreement”). We have also registered in a resale registration statement on Form S-1 declared effective by the SEC on December 31, 2025 additional securities of the Company, including those issued in further private placements conducted during 2025, as well as warrants that we have issued during 2025. The sale of a large number of shares by these stockholders, or the sale of shares by warrant holders following the exercise of these warrants, could cause the prevailing market price of shares of our common stock to decline. Significant sales of shares of our common stock may have negative pressure on the public trading price of our common stock.

The shares already registered for resale currently represent over 50% of the total number of shares outstanding, based on the number of shares of common stock outstanding as of March 24, 2026. Even though the current trading price is significantly below the Company’s initial public offering price, based on the closing price of the common stock on March 24, 2026, certain of our stockholders may have an incentive to sell their shares because they will still profit on sales due to the lower prices at which they purchased their shares as compared to the public investors who acquired shares during the GigCapital5 initial public offering. For example, members of our founding stockholder, GigAcquisitions5, who received a distribution of shares from GigAcquisitions5 for which there is an effective resale registration statement, have a cost basis in up to 1,911,696 shares of common stock that were acquired at an effective purchase price of $0.0130776 per share, and, therefore, based on the closing price of the common stock, could earn an aggregate profit of approximately $12.5 million from the resale of such shares based upon the closing stock price on March 24, 2026.

To the extent that the selling security holders under any of our registration statements on Form S-1 sell their shares or are perceived by the market as intending to sell them, the market price of shares of common stock could drop significantly. These factors could also make it more difficult for us to raise additional funds through future offerings of shares of common stock or other securities.

The Company has converted each of its resale registration statements on Form S-1 to post-effective amendments on Form S-3, which allow the selling security holders to continue to offer and sell the registered securities thereunder. In addition, the Company has an effective shelf registration statement on Form S-3 from which it may offer and sell securities from time to time. The availability of the shelf registration statement may facilitate future capital raises by the Company; however, any such offerings could result in dilution to existing stockholders and may cause the market price of our common stock to decline.

On October 3, 2025, we issued the Pre-Funded Warrants which are exercisable for 1,808,055 shares at an exercise price of $0.0003 per share. In addition, the Company has other warrants that in the aggregate are exercisable for 38,417,755 shares of common stock at various exercise prices ranging from $1.0002 per share to $6.90 per share. This includes the warrant that we issued to Lynrock Lake in connection with the Lynrock Lake Warrant, which is exercisable for 24,396,416 shares of common stock at an exercise price of $1.0002 per share, but may be exercised on a “cashless basis.”

In addition, the shares of common stock that will be issued upon exercise of stock options already granted pursuant to the terms of, or those shares of common stock reserved for future issuance under the 2024 Equity Incentive Plan will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. We have filed a registration statement on Form S-8 under the Securities Act to register shares of common stock or securities convertible into or exchangeable for shares of common stock issued pursuant to our equity incentive plans and may in the future file additional registration statements on Form S-8. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.

Certain of the Company’s warrants are accounted for as a warrant liability and were recorded at fair value upon issuance with changes in fair value each period reported in earnings, which may have an adverse effect on the market price of the common stock.

As of March 31, 2026, an aggregate of 889,364 private warrants and working capital warrants that are Warrant Agreement Warrants, which following the Reverse Stock Split were exercisable for 296,445 shares of common stock, were outstanding. These warrants became exercisable 30 days after completion of the Business Combination and are exercisable now that we have an effective registration statement under the Securities Act covering the shares of common stock of the Company issuable upon exercise for so long as a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permits holders to exercise their warrants on a cashless basis under certain circumstances). Furthermore, the Company may redeem outstanding warrants in certain circumstances; provided, however, that these warrants will not be redeemable by the Company so long as they are held by the initial purchasers or any of its permitted transferees, to which the initial purchaser transferred the private warrants in June 2024. Under GAAP, the Company is required to evaluate contingent exercise provisions of these warrants and then their settlement provisions to determine whether they should be accounted for as a warrant liability or as equity. Any settlement amount not equal to the difference between the fair value of a fixed number of the Company’s equity shares and a fixed monetary amount precludes these warrants from being considered indexed to its own stock, and therefore, from being accounted for as equity. As a result of the provision that these warrants, when held by someone other than the initial purchasers or their permitted transferees, will be redeemable by the Company, the requirements for accounting for these warrants as equity are not satisfied. Therefore, the Company is required to account for these warrants as a warrant liability and record (a) that liability at fair value, and (b) any subsequent changes in fair value as of the end of each period for which earnings are reported. The impact of changes in fair value on earnings may have an adverse effect on the market price of our common stock.

We conduct business in the Kingdom of Saudi Arabia and the UAE and military conflicts and geopolitical instability in the Middle East, including U.S. and Israeli military actions against Iran and the effective closure of the Strait of Hormuz, could disrupt our ability to ship products into the region, impair global markets and adversely affect our business and finances.

Armed conflicts and heightened geopolitical tensions in the Middle East, including ongoing U.S. and Israeli military operations against Iran launched on February 28, 2026, pose risks to the global economy and to our business, particularly as we have distribution arrangements in the Kingdom of Saudi Arabia and the UAE. Iran has retaliated across the Gulf region, including attacks against targets in Qatar, the UAE, Kuwait, Bahrain and the Kingdom of Saudi Arabia. Furthermore, starting on March 4, 2026, Iranian forces declared the Strait “closed” and have threatened and carried out attacks on ships attempting to transit the waterway. The Strait, which borders Iran and Oman, is a critical maritime choke

point through which roughly 27% of the world’s maritime trade in crude oil and petroleum products, approximately 20% of global liquefied natural gas trade, and significant volumes of containerized manufactured goods and other commodities transit. Although U.S and other forces have acted to allow for shipping to be able to continue through the Strait, uncertainty remains as to whether ships can safely transit the Strait, and at what cost, with war risk insurance premiums for vessels transiting the Strait having surged from approximately 0.25% to as much as 1-3% of a vessel’s insured value, and major maritime insurers have withdrawn war-risk coverage entirely, rendering the Strait economically non-functional even when it may be physically accessible. As a result, maritime shipping traffic through the Strait has declined by approximately 90% or more from normal volumes. A significant escalation of hostilities in this or other global conflicts may have a material adverse impact on our business. The current military conflict may affect our ability to continue our projects in these regions due to lack of resources, local support, and safety for the workers of our distribution partners. In addition, our distribution partners may be unable to receive product shipments destined for the Kingdom of Saudi Arabia and the UAE, or may experience significant delays, increased costs and supply chain interruptions that could materially impair our ability to fulfill customer orders, maintain existing distribution relationships and generate revenue from the region. Any disruption to our ability to distribute our products to this region will likely result in an impact on our finances. Furthermore, although the length and impact of the ongoing conflict is in the Middle East is highly unpredictable, it could lead to global market disruptions. The escalation of the conflict in the Middle East and the resulting measures that have been taken, and could be taken in the future, by the United States, NATO (or member countries), the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. In addition, the escalation of military action in the Middle East has disrupted global shipping routes, increased transit times and freight costs, and created broader supply chain bottlenecks. These shipping disruptions may persist even after the cessation of active hostilities, as insurance markets, operator risk perception and network redesign operate independently of military conditions, and the experience of the Red Sea crisis from 2023 to 2025 has demonstrated that commercial shipping traffic may not return to pre-crisis levels for an extended period. Furthermore, any disruption to the flow of oil through the Strait of Hormuz or other critical shipping lanes, could result in a rapid and sustained increase in global oil and energy prices, which would increase transportation and logistics costs and the cost of petroleum-based production materials. Higher energy and fuel prices would also be disruptive for the global economy and our end user customers. In addition, an escalation of military action in the Middle East could disrupt global shipping routes, increase transit times and freight costs, and create broader supply chain bottlenecks similar to those experienced during prior periods of global disruption. Any macroeconomic deterioration resulting from an escalation in Middle Eastern hostilities could compound the existing challenges facing our business and could have a material adverse effect on our business, financial condition, results of operations, and liquidity.

The extent and duration of the ongoing conflict, resulting sanctions and any related market disruptions are impossible to predict, but could be substantial, particularly if current or new sanctions continue for an extended period of time or if geopolitical tensions result in expanded military operations on a global scale. Any such disruptions may also have the effect of heightening many of the other risks described in this section. If these disruptions or other matters of global concern continue for an extensive period of time, to the extent that we have material operations or assets in a conflict zone, they may be materially adversely affected.

Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

Please refer to the Current Report on Form 8-K that we filed with the SEC on January 23, 2026 for information regarding a private placement that occurred on January 22, 2026. On January 22, 2026, we entered into the Fourth Securities Purchase Agreement where we received approximately $0.2 million from Dr. Avi Katz, the Chairman of our Board of Directors, in exchange for the issuance of (i) 24,107 shares of common stock at a per share purchase price of $6.43, which represented 110% of the 5-day volume weighted trading price for the common stock on January 22, 2026; and (ii) warrants with a term of ten years from the initial exercise date to purchase up to an additional 48,214 shares of common stock with a per share exercise price of $6.43. We used the net proceeds from the offering for working capital purposes.
