First Majestic's Output Surge Masks Looming Tax and Dividend Risks

What happened

First Majestic Silver Corp reported a 37% Q4 output growth for 2025, meeting annual targets through the Gatos Silver acquisition and strong mine performance, as highlighted in a recent Zacks article. However, the DeepValue master report cautions that this operational success is already priced into the stock at a P/E of 65.4x and EV/EBITDA of 17.2x, ignoring significant Mexico tax risks. The company achieved record FY2025 silver production of 15.4 million ounces and revenue of $1.26 billion, driven by contributions from Los Gatos and other mines. Yet, Mexico tax disputes have resulted in a net accrual of $131.5 million and frozen VAT of $124.1 million, threatening cash flows and the sustainability of the newly implemented revenue-linked dividend. With key catalysts like the Del Toro sale approvals and first dividend payment in May/June 2026 pending, investors must assess whether the momentum can withstand these underlying financial and operational pressures.

Implication

The positive production data may briefly support market sentiment, but it fails to address the cash flow threats from Mexico tax liabilities that could force dividend rollbacks or capex cuts. This reinforces the DeepValue report's WAIT rating, as the investment thesis depends on successful execution of upcoming milestones like the Los Gatos ramp to 4,000 tpd in 2H26 rather than past performance. Crowded positioning in the stock heightens vulnerability to any negative developments, such as delays in tax dispute resolutions or operational setbacks. For long-term holders, the focus should shift to verifying the first dividend payment and Del Toro sale progress in the next few months to gauge management's risk management. Ultimately, while operational strength is encouraging, investors should avoid new positions until there is clearer evidence of dividend sustainability and reduced tax overhang, given the limited margin of safety at current prices.

Thesis delta

The confirmation of strong 2025 output validates AG's operational leverage to silver prices and supports the bullish narrative around scale and growth. However, it does not alter the core investment thesis that Mexico tax disputes and high valuation necessitate a cautious, wait-and-see approach. The delta is minimal; the recommendation remains to await evidence from key catalysts, such as dividend payments and tax resolution, before reassessing the risk-adjusted return profile.
