International Business Machines (NYSE:IBM) saw its shares tumble about 17% in premarket trading on July 14, 2026, after releasing preliminary second-quarter results that fell short of analyst expectations. The tech giant reported revenue of $17.2 billion, 3.7% below consensus, and adjusted earnings per share of $2.93, a 3.0% miss. The disappointing figures underscore the financial strain of the rapid shift in customer spending toward AI-related hardware, which has cannibalized demand for IBM's higher-margin software and mainframe products.
The preliminary data, released ahead of the company's full earnings call scheduled for July 22, revealed a sharp deceleration from the first quarter. In Q1, IBM posted 9% revenue growth, with software rising 11% and infrastructure up 15%. However, Q2 saw growth slow to just 1% overall, with software at 5% and infrastructure plunging to negative 7%—a dramatic 22-percentage-point swing in infrastructure growth within a single quarter.
CEO Arvind Krishna described the outcome as "worse than our expectations," attributing the miss to a late-June surge in customer capital spending on servers, storage, and memory, which diverted funds away from IBM's Z mainframe and transaction-processing software. The company noted that "numerous large deals failed to close" and that cybersecurity concerns also distracted buyers, leading to a backlog of delayed contracts.
The profit dynamics further reveal the cost of this shift. Adjusted gross profit fell by $8 million year-over-year to $10.194 billion, while adjusted pretax income rose by $93 million to $3.290 billion—entirely due to a $101 million reduction in combined expenses and other items below the gross-profit line. Meanwhile, the gap between GAAP and adjusted earnings widened by 35% to $0.66 per share, as GAAP earnings declined 2% while adjusted earnings increased 5%. This suggests that investors are being asked to place greater reliance on exclusions at a time when revenue growth and gross margins are weakening.
Not all segments underperformed. Distributed infrastructure revenue surged 37%, ending the quarter with roughly $500 million in backlog, while Red Hat's growth accelerated to 11%. Cumulative performance of the z17 mainframe reached nearly 130% of the comparable z16 cycle. These figures support IBM's argument that timing and budget allocation—rather than a broad demand collapse—drove much of the miss. However, that explanation cuts both ways: if spending remains concentrated in supply-constrained hardware, IBM may continue sacrificing software mix and gross margin.
The company stopped short of reaffirming its April targets for more than 5% constant-currency revenue growth and about $1 billion of additional annual free cash flow, stating that it would discuss full-year expectations on the July 22 call. That call will likely focus on four key areas: conversion of delayed deals, transaction-processing sales, gross-margin recovery, and whether IBM's full-year growth and cash-flow targets survive the quarter's spending shock.
For investors, the Q2 miss serves as a cautionary tale about the costs of the AI hardware rush. While IBM's distributed infrastructure and Red Hat businesses show promise, the broader impact on software and margins raises questions about the sustainability of its growth strategy. The market's premarket reaction—a 17% drop—reflects the severity of the miss and the uncertainty ahead.
