Shares of Eos Energy Enterprises Inc. (NASDAQ: EOSE) tumbled 5.05% in after-hours trading on Wednesday following the release of the company's third-quarter financial results that fell short of analyst expectations.

The energy storage systems manufacturer reported quarterly revenue of $30.5 million, which missed the analyst consensus estimate of $39.55 million by 22.85%. While this figure represents a significant increase from $854,000 in the same period last year, it failed to meet market projections. More concerning for investors was the company's bottom line, with Eos reporting an adjusted loss of $2.77 per share, substantially wider than the expected loss of $0.23 per share.

Despite achieving its highest quarterly revenue in company history, Eos faces challenges in meeting profitability targets. The company reaffirmed its full-year revenue guidance of $150 million to $160 million, consistent with the low end of its previously forecasted range. However, the wider-than-anticipated losses suggest ongoing difficulties in scaling operations profitably. As Eos continues to ramp up production and expand its manufacturing capabilities, investors will be closely watching for signs of improved financial performance in the coming quarters.
