Investing.com — Software stocks fell sharply Tuesday as disappointing preliminary results from IBM (NYSE:IBM) rippled across the sector, pulling shares of major software companies lower.

“The IBM update will deliver a devastating blow to software/services stocks as investors will worry about the capex pivot negatively impacting the whole industry, but the race to secure hardware raises its own set of worries,” Vital Knowledge analyst Adam Crisafulli said in a quick comment.

Following IBM’s update, investors reacted sharply to the cooling sentiment in the broader software space:

Accenture (NYSE:ACN): Fell 7%

ServiceNow (NYSE:NOW): Dropped 8%

Workday (NASDAQ:WDAY): Declined 9.7%

Salesforce (NYSE:CRM): Slipped 6%

Atlassian Corp Plc (NASDAQ:TEAM): Fell 8.3%

SAP SE ADR (NYSE:SAP): Sank 5.5%

Adobe NASDAQ:ADBE): Fell 6.1%

The decline is rooted in a fundamental shift in enterprise capital expenditure (capex) caused by a global memory supply shortage. Here is why this dynamic is specifically hurting software stocks:

Capex Reprioritization: IBM reported that, toward the end of June, its clients—facing a supply-constrained market—shifted their spending away from software and general-purpose IT to “lock in” hardware like servers, storage, and memory. Because memory prices have spiked—exacerbated by intense demand from AI data centers—enterprises are exhausting their budgets just to secure critical hardware.

The AI Tax on Enterprise Budgets: The industry is currently experiencing a “structural” memory shortage. Hyperscalers and AI infrastructure providers are consuming the vast majority of high-bandwidth memory (HBM) and DRAM production. As a result, when enterprises do manage to secure hardware, they are paying significantly higher premiums, leaving less room in their annual budgets for software renewals, licensing, or new digital transformation projects.

Short-Term Revenue Headwinds: Investors are concerned that this is not an isolated issue for IBM. If large enterprise clients are delaying software purchases to prioritize hardware inventory—a trend referred to as “capex reprioritization”—it suggests a near-term revenue slowdown for the entire software-as-a-service (SaaS) and consulting sector.

IBM’s revenue of $17.2 billion missed the $17.86 billion consensus, with non-GAAP EPS of $2.93 falling short of the $3.02 estimate. Beyond the hardware buying shift, the company noted:

Infrastructure Slump: The performance shortfall was concentrated in its Z-series mainframe division and associated “Transaction Processing” software stack.

External Distractions: IBM indicated that clients were also distracted from software investment decisions during the quarter by urgent, industry-wide cybersecurity concerns, which likely took precedence over other planned software expenditures.
