Onestream Inc. (OS) saw its stock price plummet 9.91% in after-hours trading on Tuesday, following the release of the company's fourth quarter and fiscal year 2024 financial results.

For the fourth quarter, Onestream reported a net loss of $31.4 million, or $0.19 per share, on revenue of $132.5 million. While the loss was wider than expected, the company's revenue beat Wall Street's projections of $128.1 million. The strong revenue growth was driven by a 35% increase in subscription revenue compared to the prior-year quarter.

For the full year 2024, Onestream posted a net loss of $216.2 million, or $1.25 per share, on revenue of $489.4 million, representing a 30% year-over-year growth. The company's performance was impacted by significant investments in research and development, as well as sales and marketing efforts to support its expansion into new markets.

Looking ahead, Onestream provided guidance for the first quarter of 2025, projecting a loss per share between $0.04 and $0.02 on revenue ranging from $130 million to $132 million. For the full year 2025, the company expects earnings per share between $0.01 and $0.09 on revenue of $583 million to $587 million.

While Onestream's revenue growth and guidance were encouraging, investors appear to be concerned about the company's continued losses and high operating expenses. The after-hours sell-off suggests that the market may have had higher expectations for Onestream's profitability in the near term.
