IBM

In July 2026, IBM issued a preliminary Q2 2026 earnings warning, reporting lower-than-expected revenue of $17.2 billion and operating EPS of $2.93. This shortfall was attributed to clients shifting late-quarter spending towards hardware to secure supply-constrained infrastructure ahead of anticipated price increases, diverting funds from software and services, alongside a 42% decline in mainframe Z system revenue. This news caused IBM's stock to plunge over 20% in pre-market trading on July 14, 2026, marking its worst single-day fall since October 1987, though shares saw a slight increase after the full earnings release on July 22, 2026. As of October 8, 2026, IBM's stock price had decreased by 24.98% over the past three months and 21.64% over the last 12 months. IBM is scheduled to announce its third-quarter 2026 financial results on October 21, 2026.
