York Space Systems Reports First Quarter 2026 Results

Government and Commercial Wins Reinforce Execution as Company Accelerates Expansion

York Space Systems Inc. (NYSE:YSS) (York) today announced financial results for the quarter ended March 31, 2026.

* See definition and reconciliation of Adjusted EBITDA to net loss under "Non-GAAP Financial Measures" and "Reconciliation of GAAP to Non-GAAP Measures."

"Our Q1 results reflect consistent execution against the objectives we set at the start of the year and with our IPO. Our commercial momentum and IDIQ awards demonstrate continued traction, and after quarter end, our agreement to acquire ALL.SPACE represents a meaningful step in expanding our total addressable market and broadening the range of missions we can support," said Dirk Wallinger, CEO of York. "We are actively investing ahead of demand by building inventory of our satellite platforms and aligning our operations to support faster deployment timelines. That readiness is increasingly important as customers prioritize resilient, proliferated architectures and communications capabilities that can perform in more complex operating environments. Our focus remains on disciplined execution, continuing to build capacity, integrate new capabilities, and convert opportunity into awarded work."

"The team is executing well and driving strong growth," said Kevin Messerle, CFO of York. "Given the breadth of demand in front of us, we remain disciplined in how we allocate capital to maximize long-term value. The IPO has given us the opportunity to accelerate our growth by entering new but adjacent markets and building our new business footprint in the U.S. and across the world."

First Quarter 2026 Company Results

Revenue increased $10 million, or 9%, to $116 million. This increase was primarily driven by growth in our major government programs.

Gross Margin decreased 4 percentage points to 19%; Gross Profit decreased 10% to $22 million. The decrease in gross margin is largely attributable to unfavorable EAC adjustments taken in the quarter together with favorable EAC adjustments in the year-ago quarter; the decrease in gross profit is primarily driven by the same, offset by higher revenue.

Backlog increased to $642 million reflecting the new commercial contract signed in first quarter of 2026.

Selected highlights

• York completed its IPO, raising net proceeds of $583 million.

• York acquired Orbion Space Technology, strengthening its supply chain with flight-proven electric propulsion systems.

• York secured a 12-month extension from NASA and Johns Hopkins Applied Physics Laboratory (APL) for its BARD mission. This enables an expanded series of demonstrations of the Polylingual Experimental Terminal (PExT) payload throughout 2026 and into early 2027, including increased interoperability testing and direct-to-Earth (DTE) communications with commercial ground service providers, supporting near real-time commanding, telemetry, and science data transfer options for future science and operational missions.

• York was awarded multiple IDIQ contract awards across two mission areas critical to national security and defense. York will compete for, and is well-positioned to win and execute, task orders under these awards. These awards expand York's role in next-generation space and defense architectures.

• York finalized a multi-year $187 million commercial contract for a 20+ satellite constellation built on the M-CLASS platform, demonstrating continued growth in the commercial market.

• York initiated build-out of the first 20 satellite platforms for inventory, leveraging its mature production capacity and Manufacturing Readiness Level (MRL) 9 capabilities to accelerate time-to-orbit and meet growing demand for rapid, large-quantity deployments from government and commercial customers.

• In April 2026, York announced the entry into a definitive agreement to acquire ALL.SPACE, a leading provider of advanced satellite communications terminals and multi-network connectivity solutions. With the acquisition, York is creating a complete communications ecosystem that operates in contested environments across commercial and government networks. The consummation of the acquisition is subject to regulatory approvals and customary closing conditions.

Factors that could cause actual results to differ materially from those expressed or implied by the forward-looking statements include: disruptions in U.S. government operations and funding and budgetary priorities of the U.S. government; limitations on investor insight into portions of our business due to our classified contracts with the U.S. government; our failure to establish and maintain important relationships with government agencies and prime contractors; the potential inability to realize our backlog; difficulties or disruptions in consummating future acquisitions and integrating the operations of acquired companies into our business, and in realizing the expected benefits of these transactions, including with respect to Orbion Space Technology and ALL.SPACE, cost overruns on our contracts, including before final receipt of a contract; concentration of our customers and backlog; our failure to implement and maintain an effective system of internal control over financial reporting; fluctuation of our operating results; significant competition in the global space and satellite market; our failure to manage our growth effectively and our ability to achieve and maintain profitability; any failure of our spacecraft systems and related software to operate as intended, resulting in warranty claims for product failures, schedule delays or other problems with existing or new products; our revenue, results of operations and reputation may be negatively impacted if our products contain defects or fail to operate in the expected manner; our dependence on contracts entered into in the ordinary course of business and our dependence on major customers and vendors; the scarcity or unavailability of critical components used to manufacture our products or used in our development programs; the emerging and shifting nature of the market for spacecraft platforms and satellite software and its failure to achieve the growth potential we expect; uncertain global macro-economic and political conditions, including the implementation of tariffs; a failure of our information technology systems, physical or electronic security protections; the failure to adequately protect our proprietary intellectual property rights; the inability to comply with any of our contracts or meet eligibility requirements to obtain certain government contracts; government laws and regulations, particularly those relating to contracting in the defense industry; our substantial indebtedness; and the other factors set forth in our filings with the Securities and Exchange Commission. You should not place undue reliance on these forward-looking statements, which speak only as of the date stated, or if no date is stated, as of the date of this press release and the related conference call. Actual results may vary from the estimates provided. We undertake no intent or obligation to publicly update or revise any of the estimates and other forward-looking statements made in this press release, whether as a result of new information, future events or otherwise, except as required by law.

Non-GAAP Financial Measures

We believe that in addition to our results determined in accordance with U.S. generally accepted accounting principles ("GAAP"), our non-GAAP financial measures including contribution margin, contribution margin %, EBITDA, and Adjusted EBITDA provide useful information to management, investors, and analysts in assessing our financial performance and results of operations across reporting periods by excluding items we do not believe are indicative of our core operating performance. In addition to our GAAP measures, we use these non-GAAP financial measures to evaluate our operating performance, generate future operating plans, and make strategic decisions, including those relating to operating expenses and the allocation of internal resources, including budgeting for infrastructure.

These non-GAAP financial measures are used to supplement the financial information presented on a GAAP basis and should not be considered in isolation or as a substitute for the relevant GAAP measures and should be read in conjunction with information presented on a GAAP basis. Because not all companies use identical calculations, our presentation of non-GAAP measures may not be comparable to other similarly titled measures of other companies.

Non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which items are adjusted to calculate our non-GAAP financial measures. We compensate for these limitations by analyzing current and future results on a GAAP basis as well as a non-GAAP basis and also by providing GAAP measures in our public disclosures.

Contribution Margin

We refer to revenue less direct material costs of revenue as "contribution margin" and contribution margin divided by revenue as "contribution margin %." The closest comparable GAAP financial measures to contribution margin and contribution margin % are gross profit and gross profit margin %, respectively. We believe contribution margin and contribution margin % are useful measures of the variable costs that we incur in order to provide services to our customers. Our presentation of contribution margin and contribution margin % should not be construed as an inference that our future results will be unaffected by variable costs.

EBITDA and Adjusted EBITDA

We define EBITDA as net income (loss) adjusted for interest expense, interest income, income tax benefit, and depreciation and amortization. Adjusted EBITDA is defined as EBITDA adjusted for changes in the fair value of derivatives, stock-based compensation expense, transaction costs, and other non-recurring items. Net loss is the most directly comparable GAAP measure to Adjusted EBITDA. Our presentation of EBITDA and Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

For more information on our non-GAAP financial measures and a reconciliation of GAAP to non-GAAP measures, see the "Reconciliation of GAAP to Non-GAAP Results" table in this press release.

Backlog

We view backlog as a key measure of our business growth. Backlog represents our estimate of the revenue we expect to realize in future periods as a result of performing work on contracts that have been awarded to us (net of any revenue already recognized as of the backlog date). We include the aggregate expected revenue of awarded contracts in our backlog upon the execution of a legally binding agreement, even though our contracts include certain termination rights exercisable by our customers with advance notice. We exclude unexercised contract options from our backlog. Contract liabilities recognized on our consolidated balance sheets consists of payments and billings that we have received in excess of revenue that we have recognized. Because cash receipts from these contracts have not been recognized into revenue, they are included in our backlog calculation. We monitor our backlog because we believe it is a forward-looking indicator of potential sales which can be helpful to investors in evaluating the performance of our business and identifying trends over time. Although backlog reflects business associated with contracts that are considered to be firm, terminations, amendments, or contract cancellations may occur, which could result in a reduction in our total backlog and potential future revenue that is never recognized.
