York Space Systems is a leading, U.S.-based, space and defense prime(1) providing a comprehensive suite of mission-critical solutions for national security, government and commercial customers. York is one of the only space and defense primes with proprietary hardware and software capabilities designed to address customers’ complex mission requirements across the critical elements of the entire space ecosystem throughout the mission lifecycle. York is the number one provider to the U.S. Department of Defense’s (“DoD”) Proliferated Warfighter Space Architecture (“PWSA”) by number of spacecraft operating in-orbit, by number of contracts, and by variety of contract types as of September 2025. York is a partner of choice for our customers, with differentiated performance versus traditional primes based on price, speed to deployment, and sophistication of capabilities. We produce our satellites at approximately half the cost of our competitors and have been the first to deliver and launch satellites for the PWSA. York is the first and only company to demonstrate Link-16(2) connectivity from space, highlighting our unique and innovative capabilities. York is purpose built to address evolving national security space challenges and to adapt to the ongoing shift in the U.S. government’s mission needs and procurement process. We believe we are positioned to capture an outsized share of growth in our core markets. York provides customers a vertically integrated, full technology stack of solutions including design, production, integration, and operation of spacecraft with turnkey offerings to manage spacecraft and constellations throughout their entire mission lifecycle. York has significant space heritage, having flown 74 missions, created 17 products with flight heritage, and logged over four million on-orbit hours. York’s position as a prime enables us to monetize the entire space vertical from launch to mission operations, from spacecraft to payloads, and from edge computing to data transfer. York was founded in 2012 by our CEO, Dirk Wallinger, to create an innovative space technology mission prime, with a goal of meeting the evolving national security threats from space by providing mission-critical spacecraft at scale, faster, and at lower cost. We believe that York’s proven production and delivery capabilities place it among a very limited number of companies who have the capability to deliver the required solutions for the Golden Dome based on its current timeline. We provide our customers with the ability to quickly and effectively field responsive space-based technologies. Our proprietary hardware, software and mission operations solutions are designed to address the United States’ national security priorities: missile defense (crucial to the Golden Dome), counter-space capabilities, and space domain awareness. Increasing geopolitical tensions are driving near-peer adversaries to invest heavily in military space capabilities to gain advantage in orbit—the next domain in global conflict. In today’s threat environment, rapidly deployable satellites are critical to providing denied benefit in space, maintaining space superiority and countering these emerging threats. This paradigm shift in global warfighting is driving significant growth in defense spending, with the global satellite market projected to grow by approximately $320 billion to over $600 billion from 2023 to 2032 at approximately an 8% Compound Annual Growth Rate (“CAGR”), up from approximately $280 billion in 2022 according to Allied Market Research. This growth is supported by the Golden Dome, the space intelligence community and the DoD’s PWSA program. We have invested in our infrastructure and expanded our production capabilities with a goal of meeting this evolving threat while growing our backlog to approximately $642 million and 107 spacecraft as of September 30, 2025. We believe we distinguish ourselves from other space mission primes by offering a fully integrated portfolio of proprietary spacecraft, software and services. Our versatile spacecraft are built on a modular platform, allowing us to move quickly from design and development to deployment to meet our customers’ needs for their rapid response missions. In addition, we provide software throughout the space layer, bolstered by our 2023 acquisition of Emergent Space Technologies (“Emergent”), including flight control and edge computing, and we recently added more than 45 ground antennas in connection with our acquisition of ATLAS Space Operations (the “ATLAS Acquisition”). Our capabilities include a differentiated suite of spacecraft solutions with proven, common technologies. We offer the S-CLASS, LX-CLASS, and M-CLASSspacecraft, which are high-quality, low-cost satellite platforms that are proven and scalable to a wide array of space market needs. Our spacecraft are supported by proprietary satellite software enabling versatile integration of a variety of payloads for customers and supply chain commonalities across platforms. The various spacecraft classes are designed and engineered to address a broad cross section of the spacecraft market while maximizing payload accommodation. The LX-CLASS is double the mass of the S-CLASS and leverages the S-CLASS design, sharing more than 90% of its technology with the S-CLASS, to offer a specialized platform with enhanced capabilities. Similarly, the M-CLASS utilizes the previous satellite platform designs, sharing approximately 75% of its hardware and 95% of its software with the S-CLASS and LX-CLASS, while greatly enhancing scale and power for spacecraft mass up to 2,000 kg and 8kW+ peak power consumption. Our proven suite of platforms provide solutions from 100 to 2,000 kgs and enables us to serve a large total addressable market. York’s spacecraft architecture framework results in significant commonality across platforms and software, allowing for scalable solutions at lower cost. York’s three different platforms share approximately 75% of the same hardware and 95% of the software leading to significant cost reductions throughout the value chain while maximizing product quality. This approach also reduces Non-Recurring Engineering (“NRE”) cost associated with platform development while reducing failure risks inherent to a unique design. Key in-house hardware components include Command and Data Handling (“C&DH”), flight computers, Attitude Control Systems (“ACS”), Electrical Power Systems (“EPS”) and production testing. These components complement our spacecraft production while our software-enabled services underpin autonomous, resilient operations and support key defense technologies. While the standardized spacecraft architecture framework provides scalable building blocks for rapid constellation deployment, York’s proprietary software supports key elements of operational success from mission planning to ongoing mission operations. Autonomous constellation planning and hands-off operations are essential for managing the increasing quantity of spacecraft deployed in orbit. Technologies include the Multi-Mission Operations Center (“M-MOC”), a secure, autonomous, command structure that manages multiple York spacecraft, and Bastion, York’s mission-ready ground software solution, which allows operators to manage entire fleets from a single ground architecture across more than 45 antennas throughout the world. York hardware and software solutions are vertically integrated across the technology stack. Our model allows us to capture recurring revenue driven by ongoing satellite-based software and services as well as hardware replacement cycles. Once spacecraft are fielded, York provides continuous operational support, downlink antenna usage, and proprietary software solutions, including on-spacecraft upgrades during the full orbital lifespan. Contracts have historically provided a fixed cost for software maintenance with upgrade options available for purchase. The expected replacement cycle for the current portfolio of space vehicles is approximately five to six years. York’s full lifecycle solution and ongoing operational support distinguishes York from its competitors, positioning us to act as prime for the replacement and potential expansion of competitors’ aging constellations. As a result, we expect our recurring revenue to increase as the installed base of spacecraft in orbit grows, creating a highly visible revenue model, accelerating growth and increasing margins. Our cutting-edge facilities and manufacturing footprint are purpose-built to support the rapid development and production of our spacecraft. Following the opening of our 60,000 square foot Potomac facility in August 2023, we have quadrupled production capability and believe we will be able to meet demand to manufacture and test over 1,000 satellites annually, supporting our position as a leader in rapid, high volume spacecraft delivery. with the ability to reliably deliver spacecraft faster and more affordably than traditional primes. --- (1) A primary contractor (“prime”) that leads major defense programs and deals directly with the Department of Defense.
