Perimeter Solutions, SA (PRM) experienced a significant pre-market decline of 8.57% following the release of its fourth quarter 2025 financial results. The stock's sharp drop comes as investors react to the company's reported net loss for the quarter.

The company reported a Q4 net loss of $140.2 million, or $0.94 per diluted share, a stark contrast to the net income of $144.2 million reported in the same quarter last year. While adjusted earnings per share remained flat at $0.13 and revenue increased 19% to $102.8 million, the substantial GAAP loss appears to have driven negative investor sentiment in pre-market trading.

For the full year 2025, Perimeter Solutions reported a net loss of $206.4 million, further highlighting the challenging financial performance. The company's Fire Safety segment also showed weakness with a 4% decrease in Q4 net sales, though this was offset by strong growth in the Specialty Products segment.
