IBM falls despite posting better-than-expected Q1 results
Big Blue fell in after-hours trading despite reporting better-than-expected Q1 results, as it didn’t include in the release an internal metric it typically discloses to track the progress of its AI business. IBM reported:
Q1 revenue of $15.92 billion vs. the $15.63 billion FactSet consensus estimate.
Adjusted earnings per share of $1.91 vs. the $1.81 consensus expectation.
Sales of $7.05 billion at its key, high-margin software segment vs. a $6.98 billion consensus of nine analyst estimates.
Sales of $3.33 billion in its infrastructure unit, which houses its growing AI mainframe business, vs. a $3.13 billion consensus estimate.
Unlike recent earnings statements, the company made no mention of an internal metric it used to track its progress in AI, which it called its “generative AI book of business.” That metric stood at $12.5 billion at the end of 2025, per the company.
The infrastructure business is of acute interest to the market, after AI giant Anthropic announced in February that Claude Code could efficiently modernize code bases in the COBOL programming language, which serves as a cornerstone of IBM’s enterprise mainframe business. The language is still widely used in certain industries, such as airlines and finance. (ATMs, for instance, run almost entirely on COBOL.)
Anthropic’s COBOL announcement cut the legs out from under IBM. The stock plunged 13% on February 23, the day of the announcement — its worst daily drop in more than 25 years. And it was down roughly 15% for the year through the end of trading Wednesday.
