Is Eos Energy Enterprises, Inc. overvalued or undervalued?

As of 10 November 2021, Eos Energy Enterprises, Inc. has moved from a valuation grade of "does not qualify" to "risky." The company is currently considered undervalued, despite its negative financial metrics. The P/E ratio is not applicable due to the company being loss-making, while the Price to Book Value stands at -2.19, indicating significant negative equity. Additionally, the EV to EBITDA ratio is -7.06, reflecting a challenging financial position.
In comparison to its peers, Eos Energy's EV to EBITDA ratio of -7.06 is notably better than NuScale Power Corp.'s -82.7746, but worse than Microvast Holdings, Inc.'s 33.6678. This suggests that while Eos Energy is struggling, it is not the worst performer in its peer group. The company's stock has experienced a significant decline of 34.33% over the past month, contrasting with a 3.83% gain in the S&P 500 during the same period, highlighting the volatility and risk associated with its current valuation.
