IBM Sees Mainframe Sales Decline but Stands Firm on Hybrid Cloud Strategy

IBM's stock price has dropped by 9% over the past month due to a significant decline in mainframe sales. The company reported a 42% collapse in Q2 2026 mainframe sales, which spooked investors. Despite this drop, IBM is still considered fairly valued at current levels.

Software now makes up 45% of IBM's revenue and 80% of its recurring business, with Red Hat and automation segments driving growth opportunities. The company's acquisition-driven hybrid and multi-cloud software strategy is seen as compelling, but high purchase multiples leave little room for execution error.

Execution risk on recent acquisitions and rising debt warrants close monitoring, as free cash flow (FCF) and return on invested capital (ROIC) growth may lag behind invested capital in the near term. Despite these challenges, IBM's software business offers durable expansion opportunities.
