Blackline Inc. (BL), a leading provider of financial accounting software, saw its shares plunge 14.73% in after-hours trading on Tuesday, despite reporting solid financial results for the fourth quarter and full year 2024. The steep sell-off came as the company's guidance for the first quarter and full year 2025 fell short of market expectations.

For the fourth quarter of 2024, Blackline reported total revenues of $169.5 million, up 9% year-over-year, and non-GAAP operating income of $30.7 million, reflecting a non-GAAP operating margin of 18.1%. While these results exceeded analysts' estimates, the company's guidance for 2025 appeared to disappoint investors.

For the full year 2025, Blackline forecasts total revenues in the range of $699 million to $705 million and a non-GAAP operating margin of 21.0% to 22.0%. This implies a slight deceleration in revenue growth and a modest improvement in profitability compared to 2024. However, analysts were expecting stronger guidance, particularly in terms of operating margin expansion.
