Castellum Inc

In the course of conducting our business operations, we are exposed to a variety of risks. Any of the risk factors we described in Part I, Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2023 filed on March 21, 2024 have affected or could materially adversely affect our business, prospects, operating results, and financial condition. Certain statements in “Risk Factors” are forward-looking statements. See “Explanatory Note Regarding Forward-Looking Statements.”

We have added the following risk factor to those disclosed in Part I, Item 1A., Risk Factors included in our Annual Report on Form 10-K for the year ended December 31, 2023:

Our self-insurance program may expose us to significant and unexpected costs and losses.

To help control our overall long-term costs associated with employee health benefits, we began maintaining our employee medical insurance benefits on a self-insured basis effective June 1, 2024. To limit our exposure, we have third party stop-loss insurance coverage which sets a limit on our liability for both individual and aggregate claim costs. We record a liability for our estimated cost of claims incurred but unpaid as of each balance sheets date. Our estimated liability is based on assumptions we believe to be reasonable under the current circumstances and will be adjusted as warranted based on changing circumstances. It is possible, however, that our actual liabilities may exceed our estimates of losses. We may also experience an unexpectedly large number of claims that result in costs or liabilities in excess of our projections, which could cause us to record additional expenses. Our self-insurance reserves could prove to be inadequate, resulting in liabilities in excess of our available insurance and self-insurance. If a successful claim is made against us and is not covered by our insurance or exceeds our policy limits, our business may be negatively and materially impacted. These fluctuations could have a material adverse effect on our business, operating results, and financial condition.
