Is Allient, Inc. overvalued or undervalued?

As of 21 November 2025, the valuation grade for Allient, Inc. has moved from very expensive to expensive. The company appears to be overvalued based on its current metrics. Key ratios include a P/E ratio of 271, an EV to EBITDA of 12.70, and a Price to Book Value of 1.98, which are significantly higher than its peers, such as SES AI Corp. with a P/E of -4.32 and GrafTech International Ltd. with a P/E of -1.08. In terms of recent performance, Allient, Inc. has shown strong returns year-to-date at 110.30%, outperforming the S&P 500's 12.26%. However, over longer periods, such as 3 years and 5 years, its returns of 42.47% and 25.30% respectively lag behind the S&P 500's returns of 67.17% and 85.61%. This suggests that while the company has had a strong recent performance, its valuation may not be justified given its high ratios compared to peers.
