Fortuna Mining Corp. (FSM) Cash Flow Statement

The OCF/NI ratio has been consistently above 1.8 in most quarters, with a notable spike to 13.25 in 2024Q4, suggesting that non-cash charges like D&A are substantial and that earnings are backed by cash generation. However, the 2025Q3 ratio of 0.89 indicates a quarter where working capital outflows or timing issues compressed cash conversion, warranting attention to the sustainability of this metric.

The trajectory shows a clear improvement in FCF generation post-Séguéla, with 2026Q1 FCF margin at 47.9% and 2026Q2 at 22.1%, though the latter is down sequentially. This volatility is typical for a miner with varying production and shipment timing, but the overall trend suggests that FCF is now a more reliable source of shareholder value, especially compared to the negative FCF margins of some peers.

The CapEx/Rev ratio has been relatively stable, with peaks in 2026Q2 (21.3%) and 2024Q4 (20.5%), likely reflecting ongoing development at Séguéla and other projects. This suggests that FSM is investing in growth while maintaining a disciplined approach, as evidenced by its low debt levels. Investors should monitor whether this capital spending translates into sustained production growth, especially given the recent revenue decline.

The negative working capital changes in several quarters (e.g., 2024Q1, 2025Q1) suggest that FSM is building inventory or extending receivables, which can temporarily depress operating cash flow. Conversely, positive changes in 2026Q2 and 2025Q4 indicate releases of cash from working capital. This pattern is typical for miners with remote operations, but the magnitude of swings warrants monitoring to ensure they do not signal operational inefficiencies.

The buyback activity is notable, especially in 2026Q2, which may indicate management's view that the stock is undervalued. However, the lack of dividends and the concentration of buybacks in a single quarter suggest a tactical approach rather than a consistent return policy. This deployment strategy, combined with low debt, suggests a focus on enhancing shareholder value through share count reduction, but investors should assess the sustainability of this given the revenue decline.

The cumulative gap of approximately $577M is largely attributable to D&A, which totaled around $523M over the same period. This suggests that FSM's reported earnings understate its cash-generating ability, a positive signal for valuation. However, the gap also reflects the impact of working capital changes, which have been net negative, indicating that some cash is tied up in operations. This divergence supports the view that FSM's cash flow quality is high, but the recent revenue decline could narrow this gap if cash generation slows.
