IBM Investor Briefing 2021 Agenda Arvind Krishna, Chairman and Chief Executive Officer Paul Cormier, President and Chief Executive Officer, Red Hat Tom Rosamilia, Senior Vice President, Cloud and Cognitive Software Mark Foster, Senior Vice President, Global Business Services Kelly Chambliss, Senior Vice President, Americas and Strategic Sales, Global Business Services John Granger, Senior Vice President, Hybrid Cloud Services and Chief Operating Officer, Global Business Services Ric Lewis, Senior Vice President, Systems James Kavanaugh, Senior Vice President and Chief Financial Officer All presenters 3 Q&A Financial Model Infrastructure Consulting Software Red Hat Software Strategic Overview

Forward-looking statements and non-GAAP information Certain comments made in this presentation may be characterized as forward looking under the Private Securities Litigation Reform Act of 1995. Forward-looking statements are based on the company’s current assumptions regarding future business and financial performance. Those statements by their nature address matters that are uncertain to different degrees. Those statements involve a number of factors that could cause actual results to differ materially. Additional information concerning these factors is contained in the Company’s filings with the SEC. Copies are available from the SEC, from the IBM web site, or from IBM Investor Relations. Any forward-looking statement made during this presentation speaks only as of the date on which it is made. Except as required by law, the company assumes no obligation to update or revise any forward-looking statements. These charts and the associated remarks and comments are integrally related and are intended to be presented and understood together. In an effort to provide additional and useful information regarding IBM’s historical results and forward-looking financial information on a continuing operations basis, as determined by generally accepted accounting principles (GAAP), these materials contain non-GAAP financial measures, specifically 2020 free cash flow as well as a post-separation modeled free cash flow estimate. Within this presentation and speaker materials, all references to forward-looking information are estimated on a continuing operations basis, subsequent to the classification of Kyndryl as a discontinued operation upon its separation expected to occur by the end of the year. Currency rate fluctuations are not factored into mid-term model revenue growth rates. The company is unable to provide, without unreasonable efforts, certain forward-looking information as determined by GAAP, including expectations for free cash flow. The rationale for management’s use of non-GAAP information is included in Exhibit 99.2 to the company’s Form 8-K furnished with the SEC on October 4, 2021. The reconciliations of these non-GAAP financial measures to GAAP are included on the slides entitled “Non-GAAP Supplemental Materials” in this presentation. 4
