Perimeter Solutions, SA (PRM) plunged 17.62% in pre-market trading on Friday, following the release of its second-quarter 2026 financial results that fell short of analyst expectations.

The company reported a net loss of $181.6 million, or $1.11 per share, a significant widening from a loss of $32.2 million, or $0.22 per share, in the same quarter last year. Adjusted earnings per share came in at $0.35, missing the consensus estimate of $0.43. Quarterly sales rose 31% to $213.8 million, but also missed the FactSet consensus of $216.9 million.

The deeper loss was driven in part by a $266.3 million charge from founders advisory fees, which more than doubled from $96.9 million a year earlier. This fee is partially linked to the stock's performance, which had seen strong gains earlier in the year. The company also announced the acquisition of Monaco Enterprises for $120 million, expecting it to contribute over $11 million in annualized adjusted EBITDA.
