Description of Business	Description of Business KVH Industries, Inc. (together with its subsidiaries, the Company or KVH) develops, markets, and supports mobile connectivity and managed services and products for the marine and land markets. KVH’s service sales primarily represent revenue earned from satellite Internet airtime services. In March 2023, KVH began selling terminals for the Starlink Low Earth Orbit (LEO) service and in September 2023 became a Starlink authorized hardware and airtime reseller. In October 2024, we expanded our portfolio to include Starlink Local Priority data plans, which is primarily for stationary and in-motion commercial use on land. KVH further expanded its LEO service and hardware portfolio in January 2025 with the launch of OneWeb service for maritime applications. In addition, KVH provides, for monthly fixed and per-usage fees, satellite connectivity encompassing broadband Internet and Voice over Internet Protocol (VoIP) services, to its TracNet® H-series and TracPhone® V-HTS series customers via KVH’s global high-throughput satellite (HTS) network. Revenue from our cellular airtime service supplements KVH’s satellite-only airtime revenue following the July 2022 launch of the KVH ONE® hybrid network and TracNet H-series terminals and the subsequent introduction of the TracNet Coastal cellular/Wi-Fi terminal. KVH provides this combination of services and products in more than 130 countries. The May 2023 introduction of the KVH ONE OpenNet Program expanded access to KVH’s global HTS network and airtime services to non-KVH terminals. AgilePlans, KVH’s connectivity as a service offering, is a monthly subscription model that provides global connectivity to commercial maritime customers. The subscription can include KVH VSAT terminals and data service, Starlink and OneWeb terminals and data service, KVH’s CommBox™ Edge Communications Gateway and associated service licensing, VoIP, daily news, subsidized shipping and installation, and global support for a monthly fee with no minimum contract commitment. KVH offers AgilePlans subscribers a variety of airtime data plans with varying data speeds and fixed data usage levels with per megabyte overage charges. These airtime plans are similar to those that the Company offers to customers who elect to purchase or lease a TracNet H-series, TracPhone V-HTS series, Starlink, or OneWeb terminal. The Company recognizes the monthly AgilePlans subscription fee as service revenue over the service delivery period. The Company retains ownership of the hardware it provides to AgilePlans customers, who must return the hardware to KVH if they decide to terminate the service. Because KVH does not sell the hardware under AgilePlans, the Company does not recognize any product revenue when the hardware is deployed to an AgilePlans customer. KVH records the cost of the hardware used by AgilePlans customers as revenue-generating assets and depreciates the cost over an estimated useful life of two to five years. Since the Company retains ownership of the hardware, it does not accrue any warranty costs for AgilePlans hardware; however, any maintenance or refurbishment costs on the hardware are expensed in the period these costs are incurred. Service sales also include the distribution of commercially licensed entertainment, including movies, television programming, news, and music, to commercial customers in the maritime market through the KVH Media Group, along with supplemental value-added cybersecurity, email, and crew Internet services. In addition, KVH earns monthly usage fees from third-party satellite connectivity services, including VoIP, data and Internet services, provided to its Viasat/Inmarsat and Iridium customers who choose to activate their subscriptions with KVH. Service sales also include sales from product repairs and extended warranty sales. KVH’s satellite-only and hybrid products enable marine customers to receive data, VoIP, and value-added services via satellite, cellular, and shore-based Wi-Fi networks onboard commercial, leisure, and military/government vessels. In addition, the Company’s in-motion television terminals permit customers to receive live digital television via regional satellite services in marine vessels, recreational vehicles, buses and automobiles. KVH sells its products through an extensive international network of dealers and distributors. KVH also sells and leases products to service providers and end users. In February 2024, the Company announced a staged wind-down of its product manufacturing operations at its Middletown, Rhode Island location. The Company expects that it will continue its product manufacturing activities in order to generate a targeted amount of inventory of maritime satellite connectivity and satellite television terminals to meet anticipated demand and that it will cease substantially all manufacturing activity by the end of 2026. The wind-down has been extended from the end of 2025 because the reduced workforce has been prioritizing fulfillment of LEO product orders and refurbishing AgilePlan terminals over manufacturing new units. The Company expects to continue to facilitate customer transition to third-party hardware products compatible with its mobile satellite communications services. Please see Note 17 for additional details surrounding the wind-down of the Company's manufacturing activities.
