Is TriMas Corp. overvalued or undervalued?

As of 17 October 2025, the valuation grade for TriMas Corp. has moved from fair to very expensive, indicating a significant shift in its valuation outlook. The company appears overvalued based on its current metrics, with a P/E ratio of 40, an EV to EBITDA of 12.16, and a Price to Book Value of 1.54. In comparison, peers such as Advanced Drainage Systems, Inc. and Brady Corp. have P/E ratios of 27.44 and 21.28, respectively, highlighting TriMas Corp.'s premium valuation.
Despite a strong year-to-date return of 50.02% compared to the S&P 500's 13.30%, the company's long-term performance has lagged, with a 3-year return of 35.48% versus the S&P 500's 81.19%. This suggests that while TriMas Corp. has recently outperformed the benchmark, its elevated valuation metrics may not be justified in the long run.
