Is Amtech Systems, Inc. overvalued or undervalued?

As of 12 May 2025, the valuation grade for Amtech Systems, Inc. has moved from fair to risky, indicating a more cautious outlook on the company's financial health. The company appears to be overvalued, given its negative P/E ratio and poor return metrics. Key ratios include a Price to Book Value of 1.13, an EV to EBIT of -6.69, and an EV to EBITDA of -11.85, all suggesting significant financial distress.
In comparison to peers, Amtech's valuation ratios are starkly lower; for instance, Graham Corp. has a P/E ratio of 41.09, while Eastman Kodak Co. shows a more attractive P/E of 9.22. The recent stock performance shows that Amtech has outperformed the S&P 500 over the past month and year, with returns of 61.56% and 57.02%, respectively, but this does not mitigate the overall valuation concerns given its current financial metrics.
