Gartner stock crashes 28% after revenue outlook cut
Gartner shares plunged 27.6% — its worst day since 1999 — after it lowered its 2025 revenue and earnings outlook amid a slowdown in IT services demand. Clients are trimming contracts due to AI-driven efficiencies and economic headwinds. Despite a strong Q2, the revised guidance disappointed investors. The stock is up only 28% since 1993.
