CTM COO Merriman buys 2,000 shares at $0.64 amid 58.4% decline from 52-week high; stock down 34.3% in 30 days.
Andrew Merriman, Chief Operating Officer of Castellum, purchased 2,000 shares at $0.64 on 2026-03-27, bringing his holdings to 536,000 shares. This modest acquisition follows significant recent price weakness: the stock trades at $0.62, a 58.4% decline from its 52-week high of $1.49, and has fallen 34.3% over the past 30 days. Merriman has a sparse transaction history (only 1 prior buy on record across all tickers), and the company itself reported negative full-year net income despite strong 18.1% annual revenue growth. The acquisition is small relative to his existing holdings (536,000 shares) and occurs during a steep drawdown, but without a consistent pattern of well-timed purchases or public statements, the significance of the insider activity remains limited.
