Explanatory Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the “Securities Act,” and Section 21E of the Securities Exchange Act of 1934, as amended, or the “Exchange Act,” which statements involve substantial risks and uncertainties. These statements do not relate strictly to historical or current facts. Forward-looking statements involve risks and uncertainties and include statements regarding, among other things, our projected revenue growth and profitability, our growth strategies and opportunity, anticipated trends in our market and our anticipated needs for working capital. They are generally identifiable by use of the words “may,” “will,” “should,” “anticipate,” “estimate,” “plans,” “potential,” “projects,” “continuing,” “ongoing,” “expects,” “management believes,” “we believe,” “we intend,” or the negative of these words or other variations on these words or comparable terminology. In particular, these statements relate to future actions, prospective products and services, market acceptance, future performance or results of current and anticipated products and services, sales efforts, expenses, and the outcome of contingencies such as legal proceedings and financial results.

Examples of forward-looking statements in this Quarterly Report on Form 10-Q include, but are not limited to, our expectations regarding our business strategy, business prospects, operating results, operating expenses, working capital, liquidity, and capital expenditure requirements. Important assumptions relating to the forward-looking statements include, among others, assumptions regarding demand for our products and services, the cost, terms, and availability of components, pricing levels, the timing and cost of capital expenditures, competitive conditions, and general economic conditions. These statements are based on our management’s expectations, beliefs, and assumptions concerning future events affecting us, which in turn are based on currently available information. These assumptions could prove inaccurate. Although we believe that the estimates and projections reflected in the forward-looking statements are reasonable, our expectations may prove to be incorrect.

Important factors that could cause actual results to differ materially from the results and events anticipated or implied by such forward-looking statements include, but are not limited to:

•ongoing net income losses and growth trajectory;

•our ability to retain and attract senior management and other employees with suitable experience leading a public company;

•our ability to attract, retain, and develop highly qualified personnel who possess the necessary security clearances to support the specialized and sensitive nature of our work;

•our ability to raise additional capital on acceptable terms and to service our ongoing debt obligations;

•changes in political, economic, or regulatory conditions generally and in the markets in which we operate, and more specifically, the potential impact of the U.S. DOGE Service Temporary Organization on government spending and terminating contracts for convenience;

•our ongoing relationships with government entities, agencies, and teaming partners;

•overall levels of government spending on defense spending and spending on IT services, significant delays or reductions in appropriations for our programs or U.S. government funding more broadly, including a prolonged continuing resolution, government shutdown, or breach of the debt ceiling, as well as the potential imposition of sequestration in the absence of an approved budget or continuing resolution;

•our ability to win new contracts amidst increased levels of competition in contract bidding process;

•delays due to the appropriation process, change in the procurement process, and audits or cost adjustments to our contracts;

•our ability to successfully develop or commercialize new products and partner with companies that have complementary products and to successfully develop these offerings;

•our inability to receive full amounts authorized, or ongoing lack of funding, for contracts in our backlog;

•potential systems failures, security breaches, or the inability of Company employees to obtain required clearances;

•our ability successfully to execute additional acquisitions and integrate those operations into our ongoing businesses; and

•the effect of ongoing financing efforts and volatility of our common stock share price.

We operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for us to predict all of those risks, nor can we assess the impact of all of those risks on our business or the extent to which any factor may cause actual results to differ materially from those contained in any forward-looking statement. The forward-looking statements in this Quarterly Report on Form 10-Q are based on assumptions management believes are reasonable. However, due to the uncertainties associated with forward-looking statements, you should not place undue reliance on any forward-looking statements. Further, forward-looking statements speak only as of the date they are made, and unless required by law, we expressly disclaim any obligation or undertaking to publicly update any of them in light of new information, future events, or otherwise.

In this Quarterly Report on Form 10-Q, unless the context otherwise requires, all references to the “Company,” “our Company,” “we,” “our,” “us,” and “Castellum,” refer to Castellum, Inc., a Nevada corporation, and its wholly owned subsidiaries.
