Loma Negra Compañía Industrial Argentina Sociedad Anónima (LOMA) is back in focus after its board met on March 5, 2026, to advance an ordinary shareholders’ meeting centered on sustainability reporting and governance.

At a share price of $9.85, Loma Negra’s 1 month share price return of 12.68% and year to date share price return of 23.52% both point to fading short term momentum, even though the 3 year total shareholder return of 72.82% and 5 year total shareholder return of 134.17% still show a much stronger long haul result. Recent updates around its upcoming shareholders’ meeting, a 22% reduction in CO2 equivalent emissions since 2021, and the new US$60 million Class VI bond issue have arrived as the market reassesses both growth prospects and risk after a weaker Q4 2025 and higher leverage.

With the shares at $9.85 and trading at a discount to the US$15.00 analyst price target, the key question is whether recent weakness leaves Loma Negra underpriced or if the market already reflects its future growth potential.

Preferred Price-to-Sales of 2.6x: Is it justified?

Loma Negra trades on a P/S of 2.6x, which looks rich against several benchmarks even with the share price at $9.85.

The P/S ratio compares the company’s market value to its revenue, so it tells you how much investors are paying for each dollar of current sales. For a cement and building materials group like Loma Negra, this can hint at how much growth, resilience or pricing power the market is factoring into today’s price.

Within its own peer set, Loma Negra screens as good value, with its 2.6x P/S sitting below the peer average of 4.1x. Against the broader Global Basic Materials industry, however, the picture flips. The same 2.6x P/S is described as expensive versus an industry average of 1.2x. Compared to an estimated fair P/S of 1.2x, the current multiple also comes across as stretched, which points to a level the market could move toward if expectations cool.

Result: Price-to-Sales of 2.6x (OVERVALUED)

However, you also need to factor in risks such as a 23.52% year to date share price decline and higher leverage after the recent US$60 million Class VI bond issue.

Another Take: SWS DCF Points to a Different Story

Our DCF model suggests a different perspective compared with the 2.6x P/S. At $9.85, Loma Negra sits above the SWS DCF value of $7.52, which flags the shares as overvalued on this cash flow view and raises a simple question: which signal do you trust more?
