Perimeter Solutions (PRM) has drawn fresh attention after reporting fourth quarter and full year 2025 results, with higher sales alongside a swing from prior year profit to substantial net losses and wider losses per share.

Those earnings arrived after a choppy stretch for the stock, with a 1 day share price return of 0.75% and 7 day return of 3.53% sitting against a 30 day decline of 8.60% and 90 day decline of 15.08%. At the same time, the 1 year total shareholder return of about 1.6x and 3 year total shareholder return of just over 2x signal strong longer term gains even as near term momentum has softened.

With revenue rising to US$652.86 million while net loss widened to US$206.37 million, and the share price trading below some valuation estimates, investors may be asking whether Perimeter Solutions is offering a mispriced opportunity or whether the market is adequately reflecting its prospects.

Preferred Price to Sales of 5.6x: Is it justified?

On the current numbers, Perimeter Solutions is valued at a P/S of 5.6x, which sits well above both peers and the wider US Chemicals industry.

P/S compares the company’s market value to its revenue, so a higher multiple usually implies investors are paying more for each dollar of sales. For a business like Perimeter Solutions, with meaningful fire safety operations and specialty chemical exposure but still reporting net losses, that kind of premium multiple can signal that the market is placing a lot of weight on future revenue quality and potential margin improvement rather than current profitability.

Relative to similar companies, PRM screens as expensive, with its 5.6x P/S against a peer average of 1.4x and a US Chemicals industry average of 1.2x. Even compared to an estimated fair P/S ratio of 3.9x, the current level looks stretched, which suggests there is a clear gap the market could move towards if sentiment or expectations around the business change.

Result: Price-to-Sales of 5.6x (OVERVALUED)

However, the widened net loss of US$206.37 million and the premium 5.6x P/S versus peers could quickly weigh on sentiment if profit expectations are questioned.

Another View: DCF Points the Other Way

While the 5.6x P/S ratio makes Perimeter Solutions look expensive against peers, our DCF model suggests the opposite, with the share price of $24.33 trading at a 51.1% discount to an estimated future cash flow value of $49.71. Which signal do you trust more when the story is this split?
