Momentus shares plunge 13.76% intraday after Q3 2025 report shows widened net loss, higher interest expenses, and debt-related costs.

Momentus Inc. fell 13.76% intraday after reporting a widened net loss of $11.07 million for Q3 2025, up from $7.76 million year-over-year, driven by higher interest expenses and a debt extinguishment loss. Despite improved operating losses and gross profit, the earnings report highlighted a $1.08 basic/diluted loss per share, compared to $6.26 in the prior year, signaling ongoing financial strain. The 10-Q filing underscored the need for substantial additional capital to achieve profitability, raising concerns over the company’s cash flow and operational scalability. The stock’s sharp decline reflects investor disappointment over deteriorating margins and uncertain path to profitability, despite incremental progress in engineering services revenue and satellite deployment initiatives.
