IBM Provides Historical Data in Preparation for Reporting Changes December 27, 2021 This article is the last in a series IBM is posting to help investors understand its historical profile and reporting implications following the separation of Kyndryl. The purpose of this article is to provide stakeholders with a view of its historical financials which reflect both the separation of Kyndryl as well as the changes to IBM’s management structure and segment reporting. Investors and analysts now have the information needed to: x Update fourth quarter 2021 revenue and operating (non-GAAP) earnings per share estimates ahead of IBM’s fourth quarter earnings report in January. Recast historical models to reflect continuing operations and the new segments revenue and gross profit details. x Reporting Changes from Kyndryl Separation As a result of the separation, Kyndryl’s historical operational activity has been reclassified to IBM’s discontinued operations results, in accordance with the requirements of U.S. Generally Accepted Accounting Principles (GAAP). As such, IBM is now providing recast historical results on a continuing operations and discontinued operations basis. IBM’s future reporting will focus on continuing operations and the company will continue to provide an operating (non-GAAP) view of its results. As a reminder, discontinued operations do not include historical intercompany transactions between IBM and Kyndryl (e.g., purchases of IBM hardware and software) which were previously eliminated in consolidation. It also does not include the spending for shared services (e.g., finance, marketing, human resources, global sales coverage) that was transferred to Kyndryl upon separation. Therefore, IBM’s historical recast of continuing operations, in total and at the segment level, through October 2021 does not represent its go-forward continuing operations profile. To provide additional transparency to investors, IBM previously provided a baseline of its 2020 post-separation revenue, operating (non-GAAP) net income, and free cash flow, which it believes is a more representative view of its go-forward business. This view is re-attached below and has not changed from when it was published on November 4 (see Exhibit 1). 1

Implications of the Separation to IBM’s Fourth Quarter 2021 Expectations To understand the expected impact to IBM’s fourth quarter 2021 financial results, investors should familiarize themselves with the content provided in October and November of this year. x During its third quarter earnings webcast on October 20, IBM discussed the estimated impact of the Kyndryl separation (effective November 3) on its November and December consolidated results, net of the new commercial relationship: ~$3 billion revenue, $0.20-$0.25 earnings per share (Step 1). x The November 29 investor article gave investors additional information on its fourth quarter 2021 discontinued operations, including an estimate of the impact discontinued operations would have on its 4Q21 continuing operations operating (non-GAAP) results: ~$1.5 billion revenue, ~$0.25 operating (non-GAAP) earnings per share (Step 2). This discontinued operations estimate excludes spin-related transaction charges and potential Kyndryl-related, one-time non-cash items. The cumulative impact of these two items aligns fourth quarter expectations to IBM’s continuing operations basis. Segment Structure The separation of Kyndryl was an important step in advancing IBM’s platform-centric approach to capturing the hybrid cloud and AI opportunity. To further align its operating model with this approach, IBM announced on October 4 it was implementing a simplified and streamlined management structure effective immediately preceding the separation. IBM’s new segment reporting reflects this management structure, with four reportable segments: Software, Consulting, Infrastructure, and Financing (see Exhibits 2 and 3). The company will report segment revenue, gross profit, and pre-tax income for each segment. Additionally, consistent with IBM’s continuing operations reporting basis, segments do not include inter-company revenue or material profit. 2

x Software (formerly Cloud and Cognitive Software), which brings together hybrid cloud platform and software solutions to help clients predict, automate, secure, and modernize their environments. While there is little change to the overall scope of the Software segment, the company is making changes to the reported revenue categories - Hybrid Platform & Solutions and Transaction Processing. For additional transparency, within Hybrid Platform & Solutions, IBM will also report revenue growth rates for Red Hat, Automation, Data & AI, Security, and Health. Consulting (formerly Global Business Services), which helps clients design and build open, hybrid cloud architectures and optimize key workflows and business processes. While there is little change to the overall scope of the Consulting segment, the company is making changes to the revenue categories reported to better reflect the market opportunities and how we address them. Within Consulting, IBM will report revenue for: Business Transformation, Technology Consulting and Application Operations. Infrastructure, which provides trusted solutions for a hybrid cloud environment, meeting client demands for scalability, security, and capacity. Products are optimized with AI to deliver new insights for business and operations. Within Infrastructure, IBM will report revenue for Hybrid Infrastructure and Infrastructure Support. To provide additional transparency within Hybrid Infrastructure, IBM will report revenue growth rates for IBM Z and Distributed Infrastructure. Financing (formerly IBM Global Financing) is IBM’s captive financing business. The financing arrangements are predominantly for products or services that are critical to the end users’ business operations and support IBM’s hybrid cloud platform and AI strategy. x x x IBM Mid-term Model (2022-2024) This historical information together with the information IBM provided in its October 4 investor briefing, which detailed its mid-term model of mid-single digit revenue and high-single digit free cash flow growth, enables investors to update their forward-looking financial models (see Exhibits 4 and 5). 3

Future Investor Communications The company will report under a continuing operations basis with the new structure starting with its fourth quarter 2021 results, which it expects to announce on January 24, 2022. At this time, it will also provide further information on its 2022 outlook (see Exhibit 6). Additional information about IBM can be found on its investor website at www.ibm.com/investor.

Forward-looking statements and non-GAAP information: Except for the historical information and discussions contained herein, certain statements made in this investor relations article 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 and 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 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. This article, the below-mentioned rationale for management’s use of non-GAAP metrics and the below-mentioned reconciliations are integrally related and are intended to be presented and understood together. In an effort to provide better transparency into IBM’s operational 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, including “operating” earnings, free cash flow, as well as a post-separation modeled free cash flow estimate and pro forma earnings. The rationale for management’s use of non-GAAP information and a reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measures are included in Exhibit 99.2 to the company’s Form 8-K furnished with the SEC on December 27, 2021. >?

EXHIBIT 99.2 IBM Consolidated (GAAP) Results as Adjusted for Discontinued Operations With the completion of the separation of Kyndryl on November 3, 2021, management is providing historical results as adjusted for discontinued operations in accordance with the requirements of U.S. Generally Accepted Accounting Principles (GAAP). Kyndryl’s historical operational activity will be presented as discontinued operations in the company’s Consolidated Financial Statements beginning in the fourth quarter of 2021. Non-GAAP Financial Information Operating and Pro Forma Operating (non-GAAP) earnings In an effort to provide transparency into the operational results of the business, management has provided operating (non-GAAP) earnings from continuing operations and pro forma operating (non-GAAP) earnings from continuing operations (referred to in Exhibit 1 of Exhibit 99.1 of this Form 8-K as Post-separation Baseline Operating Net Income), non-GAAP measures that exclude the effects of certain acquisition-related charges, intangible asset amortization, expense resulting from basis differences on equity method investments, retirement-related costs and their related tax impacts. Due to the unique, non-recurring nature of the enactment of the U.S. Tax Cuts and Jobs Act (U.S. tax reform), management characterizes the one-time provisional charge recorded in the fourth quarter of 2017 and adjustments to that charge as non-operating. Adjustments include true-ups, accounting elections and any changes to regulations, laws, audit adjustments, etc. that affect the recorded one-time charge. For acquisitions, operating and pro forma operating (non-GAAP) earnings exclude the amortization of purchased intangible assets and acquisition-related charges such as in-process research and development, transaction costs, applicable retention, restructuring and related expenses, tax charges related to acquisition integration and pre-closing charges, such as financing costs. These charges are excluded as they may be inconsistent in amount and timing from period to period and are significantly impacted by the size, type and frequency of the company’s acquisitions. All other spending for acquired companies is included in earnings from continuing operations and in both operating and pro forma operating (non-GAAP) earnings. For retirement-related costs, management characterizes certain items as operating and others as non-operating, consistent with GAAP. The company includes defined benefit plan and nonpension postretirement benefit plan service costs, multi-employer plan costs and the cost of defined contribution plans in operating earnings. Non-operating retirement-related costs include defined benefit plan and nonpension postretirement benefit plan amortization of prior service costs, interest cost, expected return on plan assets, amortized actuarial gains/losses, the impacts of any plan curtailments/settlements and pension insolvency costs and other costs. Non-operating retirement-related costs are primarily related to changes in pension plan assets and liabilities which are tied to financial market performance, and the company considers these costs to be outside of the operational performance of the business. The pro forma operating (non-GAAP) earnings also includes management adjustments that did not meet the requirements to be presented as discontinued operations. Management adjustments include certain general corporate overhead costs associated with labor and benefits for shared resources transferred to Kyndryl that the company does not intend to backfill. Management believes the resource transfers and costs which were used as the basis for the management adjustments are reasonable and representative of the labor-based cost reductions the company will realize after the separation of Kyndryl. Overall, management believes that supplementally providing investors with a view of operating and pro forma operating (non-GAAP) earnings as described above provides increased transparency and clarity into both the operational results of the business and the performance of the company’s pension plans; improves visibility to management decisions and their impacts on operational performance; enables better comparison to peer companies; and allows the company to provide a long-term strategic view of the business going forward.

The below table reconciles the non-GAAP financial information contained in Exhibit 1 of the investor relations article which was posted to IBM’s Investor Relations website on December 27, 2021 and is included as Exhibit 99.1 in this Form 8-K: Year Ended December 31, 2020 ($ in billions) Historical Pro Forma (1) Management adjustments — 0.4 Sub-total $ 5.5 $ 5.6 Acquisition-related charges 1.9 1.8 U.S. tax reform impacts (0.1) (0.1) Tax effect of adjustments (0.6) (0.6) (1) The company’s unaudited Pro Forma Condensed Consolidated Income Statement is included in Exhibit 99.3 to the company’s Form 8-K furnished with the SEC on November 4, 2021 (2) The pro forma income from continuing operations already excludes certain Kyndryl separation-related charges that were included in the Kyndryl Discontinued Operations adjustment column of the unaudited Pro Forma Condensed Consolidated Income Statement. Kyndryl's impact on fourth quarter of 2021 Operating (non-GAAP) earnings per share Management has also provided within these materials an estimate of the impact on its fourth quarter of 2021 operating (non-GAAP) earnings per share as a result of reclassifying Kyndryl's operational activity to discontinued operations following the separation on November 3rd. This estimated impact represents adjusted discontinued operations earnings per share, a non-GAAP measure, which does not include Kyndryl separation-related transaction charges and potential one-time non-cash items (e.g., impairments) related to the Kyndryl separation. Direct and incremental separation-related transaction charges incurred to accomplish the Kyndryl separation include transaction and third-party support costs, business separation and applicable employee retention fees, pension settlement charges, and related tax charges. The company is not able to provide a reconciliation of this non-GAAP measure to the corresponding GAAP measure at this time because of the uncertainty as well as variability in amount of the potential one-time non-cash items related to the Kyndryl separation. Free Cash Flow / Modeled Free Cash Flow The company uses free cash flow as a measure to evaluate its operating results, plan shareholder return levels, strategic investments and assess its ability and need to incur and service debt. The entire free cash flow amount is not necessarily available for discretionary expenditures. The company defines IBM free cash flow as net cash from operating activities less the change in Global Financing receivables and net capital expenditures, including the investment in software. A key objective of the Global Financing business is to generate strong returns on equity, and our Global Financing receivables are the basis for growth. Accordingly, management considers Global Financing receivables as a profit-generating investment, not as working capital that should be minimized for efficiency. Therefore, management presents free cash flow that excludes the effect of Global Financing receivables. Since the company views Global Financing receivables as a profit-generating investment which it seeks to maximize, it is not considered when formulating guidance for adjusted free cash flow. As a result, the company does not estimate a GAAP Net Cash from Operations expectation metric. Operating (non-GAAP) net income$7.8$7.7 Separation-related charges(2)0.0— Non-operating retirement-related costs/(income)1.11.1 Non-operating adjustments: Tax effect of adjustments—(0.1) Income from continuing operations$5.5$5.3

The company has also provided a 2020 post-separation IBM modeled free cash flow estimate to provide insight into IBM’s estimated free cash flow following the separation of Kyndryl. The company defines IBM modeled free cash flow as IBM free cash flow, less Kyndryl’s modeled free cash flow. Kyndryl’s modeled free cash flow is estimated based on Kyndryl’s 2020 historical financial statements, prepared on a carve-out basis under U.S. GAAP. The carve-out methodologies and principles may not be reflective of the results of operations, financial position and cash flows had Kyndryl been a separate company. Therefore, the company includes adjustments to reflect a more representative view of Kyndryl cash flows. The adjustments primarily relate to new commercial pricing arrangements and contract scope changes as well as a net reduction in expense compared to the allocated expenses from IBM included in Kyndryl’s historical financial statements. The below table reconciles the non-GAAP financial information contained in Exhibit 1 of the investor relations article which was posted to IBM’s Investor Relations website on December 27, 2021: Year Ended ($ in billions) December 31, 2020 Less: change in Global Financing (GF) Receivables 4.3 Free Cash Flow $ 10.8 IBM Modeled Free Cash Flow $ 10.0 (1) See table below for the reconciliation of Kyndryl Modeled Free Cash Flow.

(2) Reflects the net reduction in costs for corporate overhead, primarily due to a flatter cost structure as Kyndryl becomes a stand-alone public entity. If Kyndryl decides to reduce resources or invest more heavily in certain areas in the future, that will be part of its discretionary future decisions and have not been included in this calculation.
