First Majestic Silver vs. MP Materials: Which Metals Stock Is a Better Buy in 2026?

Choosing between precious metals and critical rare earths requires balancing traditional mining stability against high-tech growth potential. Is First Majestic Silver Corp (NYSE:AG) or MP Materials Corp (NYSE:MP) the better addition for your portfolio today?

First Majestic focuses on maximizing silver and gold production through underground mining operations in North America. MP Materials provides the materials necessary for electric vehicles and defense systems. Both companies operate within the metal stocks industry, yet they offer very different financial profiles for investors looking toward 2026.

The case for First Majestic Silver

First Majestic Silver focuses on mining silver and gold within Mexico and the United States. It operates four primary underground mines, including San Dimas, Santa Elena, La Encantada, and Los Gatos. The company manages a workforce of more than 5,100 employees to supply physical metals to global markets. Customer concentration is not disclosed as a significant factor in its latest annual report, filed for the most recent fiscal period.

In FY 2025, revenue reached nearly $1.3 billion (the company reports in Canadian dollars; they have been converted to U.S. dollars here), representing a significant growth of approximately 128% compared to the prior year. This sharp increase helped the company achieve net income of close to $168 million, a major improvement from the net loss reported in FY 2024. The net margin, which measures the percentage of revenue kept as profit, stood at roughly 13% for the period.

As of its December 2025 balance sheet, the debt-to-equity ratio is approximately 0.1x. This ratio shows that for every dollar of shareholder equity, the company has roughly ten cents in total debt. The so-called current ratio, which measures the ability to pay short-term bills, is close to 2.6x. Free cash flow, which is cash from operations minus capital spending, reached approximately $352 million during the year.

The case for MP Materials

MP Materials operates as the only fully integrated rare earth producer in the United States. It mines materials at its Mountain Pass facility and manufactures magnets at its Independence facility in Texas. Major customers include General Motors Corp (NYSE:GM), Apple Inc (NASDAQ:AAPL), and the U.S. Department of Defense. Customer concentration like this adds a layer of risk to the business, particularly given the reliance on government offtake agreements.

In FY 2025, revenue reached approximately $224 million, showing a year-over-year growth of more than 10%. Despite this growth, the company reported a net loss of close to $86 million. This resulted in a negative net margin of roughly 38.3% for the fiscal year as the company continues to invest in scaling its production capabilities.

As of its December 2025 balance sheet, the current ratio is approximately 7.2x, indicating a strong ability to cover short-term obligations. The debt-to-equity ratio is close to 0.4x, showing that total debt is about 40% of the value of shareholder equity. Free cash flow was negative at nearly $328.1 million, reflecting the high costs of building out its downstream magnet manufacturing infrastructure.

Risk profile comparison

First Majestic Silver faces risks inherent to the mining industry, including fluctuating commodity prices for silver and gold. Operational risks at its underground mines in Mexico and the United States could impact production targets or safety standards. Additionally, the company must manage regulatory changes in its mining jurisdictions which could increase costs or limit expansion opportunities for new deposits.

MP Materials is highly reliant on its partnership with the U.S. Department of Defense for funding and strategic support. Scaling its magnet manufacturing facilities involves significant capital risks and potential construction delays at the Independence and 10X facilities. Furthermore, the company faces intense competition from low-cost Chinese producers and must protect its proprietary technology from competitors such as USA Rare Earth Inc (NASDAQ:USAR).

Valuation comparison

First Majestic Silver appears to be the more value-oriented choice, trading at a lower P/S ratio. First Majestic Silver has a more reasonable Forward P/E than its peer.

Which stock would I buy in 2026?

Each of these companies provides exposure to metals, but at very different ends of the market.

First Majestic Silver is involved in precious metals. Both gold and silver have been having one of their best runs in decades. Gold has more than doubled over the past two years as investors have flocked to the yellow metal for its historic inflation-hedging characteristics. Silver has nearly tripled since the start of 2025, partly in tandem with gold and partly due to industrial demand from renewable energy applications. Even with profit-taking clipping the gains in recent weeks, both metals have held on to the majority of their gains since the rally took off at the start of 2024.

The benefit of a mining stock as opposed to buying the physical metal directly or through a fund is that, as prices rise, so do profits, because early in the bull market, production prices don't rise as fast as the market price. Management can also return profits to shareholders as dividends and pursue other value-creation methods, such as selling to a larger competitor, which is not unusual in the metals business.

MP Materials is in the rare earth metals business, where pricing is largely opaque, and investors can't buy the metals directly. Given the U.S. government's desire to reduce the country's reliance on Chinese-sourced rare earths, MP is gaining significant market support.

These are both companies where Wall Street analysts expect sales and profits to rise notably in the coming years. First Majestic Silver, however, is more at risk of going down because the forward-looking market may not believe silver can advance much further.

MP, meanwhile, can be seen as critical to national security and to renewable energy production because of the role of rare earths in each. Analysts expect it to turn a profit in 2027 and approach $1 billion in revenue in 2028. With no commodity futures arbitrage to worry about, it's less likely to be subject to the vagaries of the commodity cycle.

For the long-term, go with MP Materials.
