International Business Machines (IBM) 8-K Results of Operations and Financial Condition

Exhibit 99.2

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 tables below reconcile the non-GAAP financial information contained in Exhibit 7 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:

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.
