IBM just had the kind of day that makes investor relations teams update their resumes. The 113-year-old tech giant watched its stock crater as much as 25% on July 14 after pre-announcing quarterly results that missed Wall Street expectations, marking the company’s largest single-day percentage decline on record since at least 1968.
What went wrong at Big Blue
IBM reported Q2 2026 revenue of $17.2 billion against a consensus estimate of roughly $17.9 billion. Adjusted earnings per share came in at $2.93, also falling short of what analysts had penciled in.
The culprit, according to CEO Arvind Krishna, was an unexpected shift in how clients are spending their money. Companies are redirecting capital away from IBM’s traditional software solutions, including its storied Z System mainframe line, and toward AI hardware, servers, and memory instead.
The numbers tell the story clearly. Software revenue grew 5% year-over-year, while infrastructure revenue declined 7%. Krishna pointed to the “magnitude of the capex reprioritization” as something the company simply didn’t see coming.
