SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (this “Quarterly Report on Form 10-Q”) contains forward-looking statements within the meaning of, and we intend such forward-looking statements to be covered by, the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified. These risks and other factors include, but are not limited to, those listed under “Risk Factors” in Item 1A of Part I of our Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 Annual Report on Form 10-K”). In some cases, you can identify forward-looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “objective,” “ongoing,” “plan,” “predict,” “project,” “potential,” “should,” “will,” “would,” or the negative of these terms or other comparable terminology. In particular, statements about the markets in which we operate, including growth of our various markets, statements about potential new products and product innovation and our expectations, beliefs, plans, strategies, objectives, prospects, assumptions, or future events or performance contained in the section ‘Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 2 Part I of this Quarterly Report on Form 10-Q are forward-looking statements. Forward-looking statements include, but are not limited to, statements about:

•our market opportunity, addressable market and the potential growth of that market;

•our M&A strategy, business plans, inventory building, outcomes, and growth prospects;

•Expectations regarding government agencies, programs and actions;

•the timing consummation and acquisition of All.Space Holdings, inc. ("All.Space");

•benefits expected from the acquisitions of Orbion Space Technologies, Inc. ("Orbion") and All.Space;

•trends in our industry and markets; and

•the competitive environment in which we operate.

Some of the 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 and All.Space;

•we may experience cost overruns on our contracts, including before final receipt of a contract, which would require us to absorb the excess costs and potentially reduce our cash flow and profitability;

•concentration of our customers and backlog;

•we may fail to implement and maintain an effective system of internal control over financial reporting, and as a result may not be able to accurately determine or disclose our financial results;

•our operating results may fluctuate significantly;

•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;

ii

•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 market for spacecraft platforms and satellite software is still emerging and shifting, and the market may not 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;

•adverse publicity stemming from any incident involving us, our competitors, or our customers;

•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;

•our business is subject to a wide variety of extensive and evolving government laws and regulations and contracting in the defense industry is subject to significant regulation;

•we have substantial indebtedness, and we may not be able to generate sufficient cash to service all of such indebtedness; and

•the other factors set forth under “Risk Factors” in Item 1A of Part I of the 2025 Annual Report on Form 10-K.

We have based the forward-looking statements contained in this Quarterly Report on Form 10-Q primarily on our current expectations and projections about future events and trends that we believe may affect our business, financial condition, results of operations, prospects, business strategy, and financial needs. The outcome of the events described in these forward-looking statements is subject to risks, uncertainties, assumptions, and other factors described under “Risk Factors” in Item 1A of Part I of our 2025 Annual Report on Form 10-K and elsewhere in our 2025 Annual Report on Form 10-K. These risks are not exhaustive. Other sections of our 2025 Annual Report on Form 10-K and this Quarterly Report on Form 10-Q include additional factors that could adversely affect our business and financial performance. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible for us to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this Quarterly Report on Form 10-Q. We cannot be sure that the results, events, and circumstances reflected in the forward-looking statements will be achieved or occur, and actual results, events or circumstances could differ materially from those described in, or implied by, the forward-looking statements. We undertake no obligation to update any forward-looking statements made in this Quarterly Report on Form 10-Q to reflect events or circumstances after such date or to reflect new information or the occurrence of unanticipated events, except as required by law.

In addition, statements that “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based upon information available to us as of the date of this Quarterly Report on Form 10-Q, and while we believe that information forms a reasonable basis for such statements, that information may be limited or incomplete, and our statements should not be read to indicate that we have conducted an exhaustive inquiry into, or review of, all potentially available relevant information.
