Castellum, Inc. furnished a current report stating it has issued a press release announcing financial results for the three months ended June 30, 2025. The press release is attached to the filing as Exhibit 99.1 and the filing also references an interactive data file as Exhibit 104.

Castellum, Inc. reported quarterly revenue of $14.02 million and six‑month revenue of $25.69 million, increases of 22% and 12% year‑over‑year, driven largely by a $103.3 million GTMR contract award and organic labor growth. Gross profit rose to $5.06 million for the quarter and $9.62 million for six months, while net loss narrowed to $0.35 million for the quarter and $1.55 million for six months.

Liquidity strengthened with cash of $14.73 million at June 30, 2025 and total liabilities reduced to $11.67 million, reflecting repayment of the revolver and principal paydowns on notes. Backlog totaled $201.99 million (funded $18.35 million, unfunded $22.45 million, priced options $161.19 million), with management expecting ~22% to be recognized within 12 months. Key risks noted in the filing include heavy customer concentration (three government customers represented 70% of revenue) and a significant accumulated deficit of $(55.63) million.
