Company Overview

IBM, nicknamed Big Blue, is one of the oldest technology companies still operating at scale. It missed the consumer internet and smartphone eras, sold its PC business to Lenovo in 2005, and spun off its managed infrastructure services unit as Kyndryl in 2021. What remains is a business-to-business company with four segments: Software, Consulting, Infrastructure, and Financing. In FY2025 it reported $67.5 billion in revenue and $10.6 billion in net income, with software the largest segment at about $30 billion. Its customers are mostly large banks, insurers, airlines, retailers, and governments that run critical systems on IBM Z mainframes and want help connecting those systems to public clouds and AI. The company is headquartered in Armonk, New York. The incredibly legendary American technology pioneer was founded in 1911, essentially inventing the modern computer industry with mainframes before surviving near-bankruptcy to pivot massively into hybrid cloud and AI consulting.

Key Decisions & Impact

Krishna became CEO in April 2020 and chairman in 2021. He completed the Kyndryl spin-off in November 2021, launched watsonx in 2023, and kept buying software companies to extend the Red Hat hybrid cloud platform, including Turbonomic (2021), Apptio (2023), HashiCorp (closed February 2025), and Confluent (closed March 2026). Since 2022, IBM has grown revenue every year, reaching $67.5 billion in FY2025.

Legacy

Krishna, a long-time IBM Research and software executive, led the Red Hat acquisition before becoming CEO. His tenure has made software IBM's largest segment, at about 44% of FY2025 revenue, and has refocused the company on hybrid cloud, enterprise AI, and quantum computing.

Louis V. Gerstner Jr.

Chairman and CEO

1993 – 2002

9 years

Key Decisions & Impact

Lou Gerstner saved IBM from probable breakup when he arrived in 1993 as the company posted $8 billion in losses. His critical decision was to keep IBM together as an integrated company rather than splitting it into separate hardware, software, and services units - the opposite of what Wall Street demanded. He then pivoted IBM toward services and enterprise solutions, built IBM Global Services into the world's largest IT services organization, acquired Lotus and Tivoli to build software capabilities, and restored financial discipline. Gerstner proved that IBM's greatest asset was its ability to integrate technology for large enterprises.

Legacy

Gerstner was the first IBM CEO hired from outside the company, coming from RJR Nabisco and American Express. He cut costs, cut mainframe prices, kept the company whole, and grew services into IBM's largest business. He described the turnaround in his 2002 book "Who Says Elephants Can't Dance?"

Challenges & Strategic Context

IBM's biggest challenge is turning its software portfolio into steady growth that does not depend on the mainframe cycle. Q2 2026 showed the risk: IBM Z revenue dropped sharply after the record z17 launch, and some large software deals slipped, which led IBM to lower its 2026 revenue growth outlook. Consulting has been roughly flat as clients delay discretionary projects, and AI coding and automation tools may reduce the billable hours that consulting relies on. IBM also has to integrate HashiCorp and Confluent, keep Red Hat's open-source culture intact, and compete for AI talent against hyperscalers and model labs. Perception is a lasting problem too: many developers still see IBM as a legacy vendor.
