After shocking quarter, IBM says AI isn't killing mainframes
After shocking quarter IBM results hit hard: shares plunged 25% as mainframe sales slumped 42%, missing Wall Street targets. CEO Arvind Krishna says AI did not kill the mainframe—it temporarily diverted corporate hardware budgets toward pricier AI-related gear. Leadership insists customers will still buy new systems and sees no migration off the platform.
Key Takeaways
- IBM reported $17.2 billion in revenue and $2.2 billion in net earnings, but results badly missed Wall Street expectations.
- Mainframe sales fell 42%, and the stock suffered its biggest single-day decline ever—about 25%—after a pre-earnings warning.
- CEO Arvind Krishna says customers shifted budgets to other hardware facing 15%–30% cost spikes tied to the AI boom.
- IBM lowered full-year growth forecasts; executives call the mainframe pause temporary and say some buyers have already returned.
What went wrong after IBM's shocking quarter?
On Wednesday, the 115-year-old company officially reported earnings that confirmed what investors already feared. Revenue hit $17.2 billion, with $9.9 billion in gross profit, nearly 58% margins, and $2.2 billion in net earnings—still a cash machine, but far short of expectations.
Last week, CEO Arvind Krishna and the board warned early that results were "worse than our expectations." A letter to investors flagged abysmal infrastructure revenue and weaker profit margins. Shares tanked roughly 25% in a single day, the worst drop in IBM's history, after years of solid performance under Krishna's six-year tenure.
IBM also cut its full-year growth forecasts. The core problem: its cash-cow mainframe business was down 42%. As CFO Jim Kavanaugh noted, IBM earns about $3 in software revenue for every $1 of mainframe hardware sold—so the hardware miss cascades.
Is AI really killing the mainframe?
Krishna and Kavanaugh say no. "Tens" of customers due to buy new mainframes this quarter simply deferred. Mainframes cost hundreds of thousands to millions of dollars, with maintenance and software adding many millions more—so a small customer count still moves the needle.
The same AI boom that had lifted IBM also undercut it. Clients faced astronomically high cost increases of 15% to 30% for data center gear and PCs and redirected budget there, Krishna explained. Enterprise vendors such as Dell and HP have warned that AI-driven component costs—especially memory—forced price hikes; Apple has said the same.
According to TechCrunch's report, Krishna stressed: "We see no evidence of clients moving off the mainframe." He said some deferred buyers have already purchased this quarter.
Will IBM's mainframe business bounce back?
Executives framed the slump as a temporary budget reallocation, not a structural exit. They expect those customers to buy new mainframes—and the attached software contracts—eventually.
The tech industry has predicted the mainframe's demise for decades. After this shocking quarter, IBM's bet is that even AI won't finish the job—though investors will need subsequent quarters to prove the rebound is real.
