Securities law firm Bleichmar Fonti & Auld LLP is investigating IBM for potential securities fraud. The inquiry follows a stock price collapse of over 25% on July 14, 2026.

Investigators are examining whether IBM misled shareholders about its IBM Z product outlook and the pace of new business deals. The company reported disappointing second-quarter financial results during the same period.

IBM attributed the shortfall to its Z-series performance and admitted it failed to move quickly enough. These internal delays reportedly stalled numerous large-scale business contracts.
