Foolish Take

Amid a staggering stock run, Perimeter Solutions had quietly grown into an outsized position. Even after trimming roughly $6 million worth of stock, it still represents 11% of the portfolio and remains the fund’s second-largest holding. That’s not a retreat. That’s risk management.

Operationally, the business continues to fire. Third-quarter revenue rose 9% year over year to $315.4 million, while adjusted EBITDA climbed 9% to $186.3 million, driven by strength in Fire Safety products, where segment EBITDA jumped 13%. Year-to-date adjusted EBITDA is up 20%, and adjusted EPS for the quarter came in at $0.82, up from $0.75 a year earlier.

After a rally like this, trimming a portion helps rebalance exposure without abandoning the thesis. Basically, the fund didn’t exit. It recalibrated. For long-term investors, that’s the takeaway. Selling a bit after a big win doesn’t mean you’re wrong. In fact, it can just be that you were right all along.
