Key highlights:

  • IBM stock plunged nearly 26%, wiping out roughly $55 billion in market value
  • The company reported Q2 revenue of $17.2 billion, missing Wall Street estimates of $17.86 billion
  • CEO Arvind Krishna blamed delayed client spending, infrastructure purchases, and cybersecurity disruptions for the shortfall

IBM shares suffered one of the largest single-day declines in the company's modern history after disappointing second-quarter results sparked a massive sell-off across Wall Street.

The stock plunged nearly 26%, erasing approximately $55 billion in market capitalization as investors reacted to weaker-than-expected earnings and signs of slowing demand across key business segments.

 

The stock price had not seen a collapse of that magnitude since 1972 when IBM went public. 

At the time of writing, IBM was trading around $214.82, a sharp decline from the $288.80 level where the stock traded before the earnings release. The move effectively erased months of gains, with IBM having rallied roughly 21% over the previous three months before the dramatic reversal.

Earnings miss triggers historic sell-off

The sell-off came after IBM reported preliminary second-quarter results that fell short of analyst expectations across several key metrics.

The company posted adjusted earnings per share of $2.93, below the consensus estimate of $3.02 per share. Revenue came in at $17.2 billion, missing Wall Street forecasts of $17.86 billion.

Investors were particularly concerned by weakness in IBM's core business lines. Software revenue grew just 5%, consulting revenue remained flat, and infrastructure revenue declined 7%, highlighting challenges across multiple segments of the business.

The disappointing figures caught investors off guard given the optimism surrounding enterprise AI adoption and IBM's positioning as a beneficiary of the growing demand for artificial intelligence solutions.

CEO points to shifting customer spending patterns

In a letter to investors, IBM CEO Arvind Krishna attributed the earnings shortfall to an unexpected shift in customer spending priorities during the final weeks of the quarter.

According to Krishna, many enterprise customers redirected capital expenditures toward servers, storage systems, and memory purchases in anticipation of future price increases and supply constraints.

"In the last few weeks of June, we saw clients shift their quarterly capex spend toward servers, storage, and memory purchases to secure supply-constrained infrastructure ahead of expected price increases," Krishna said.

The CEO acknowledged that management underestimated the scale of the spending shift and its impact on IBM's software and infrastructure businesses.

Krishna also cited rapidly evolving cybersecurity concerns that distracted customers and delayed purchasing decisions during the quarter.

Delayed deals add to investor concerns

Perhaps most concerning for investors was management's admission that several large deals failed to close within the expected timeframe.

"We did not adapt and move quickly enough," Krishna told shareholders, acknowledging execution challenges as clients reassessed spending priorities.

The comments raised concerns that IBM's issues extend beyond temporary macroeconomic headwinds and may reflect broader operational challenges at a time when technology companies are competing aggressively for AI-related enterprise spending.

The sharp decline also pushed IBM shares to levels not seen in decades relative to the company's recent valuation trajectory, underscoring the severity of the market's reaction.
