GitLab Inc. (GTLB) shares plummeted 8.69% in post-market trading on Tuesday, following the release of its third-quarter fiscal 2026 earnings report. The sharp decline came despite the company reporting revenue of $244.4 million, a 25% year-over-year increase that surpassed analyst estimates.

Investors reacted negatively to GitLab's unexpected GAAP loss of $8.3 million, a swing from a profit of $29.1 million in the same quarter last year. While adjusted earnings of $0.25 per share exceeded expectations, concerns over profitability and the announcement of a new CFO, Jessica Ross, effective January 2026, weighed on sentiment. The company also raised its full-year revenue and adjusted EPS guidance, but the market focused on the mixed signals in its financial performance.
