The firm added to scrutiny already launched by Pomerantz and Bleichmar Fonti & Auld, citing April growth assurances, weak IBM Z performance and large deals that failed to close.
Hagens Berman is investigating International Business Machines Corporation for potential U.S. securities law violations, adding to earlier probes by Pomerantz LLP and Bleichmar Fonti & Auld LLP after IBM's July 14, 2026 second-quarter shortfall sent the shares down $73.16, or 25.21%, to $217.07 and wiped out more than $68 billion in market value. The firm said its review is focused on IBM's statements about IBM Z after IBM reported on April 22 that Infrastructure, Hybrid Infrastructure and IBM Z revenue had risen 15%, 28% and 51%, respectively, and management said that start supported confidence in "5-plus percent" constant-currency revenue growth for 2026 and a similar growth rate in the second quarter. On July 14, IBM said total revenue rose 1% and Infrastructure revenue fell 7%, with CEO Arvind Krishna attributing the miss to a "shortfall in our Z performance and the associated software stack, primarily in Transaction Processing," customer "capex reprioritization" and numerous large deals that failed to close.
