Item 2.02 Results of Operations and Financial Condition

On October 24, 2025, Illinois Tool Works Inc. (the "Company") announced its 2025 third quarter results of operations in the press release furnished as Exhibit 99.1.

Non-GAAP Financial Measures

The Company uses free cash flow to measure cash flow generated by operations that is available for dividends, share repurchases, acquisitions and debt repayment. The Company believes this non-GAAP financial measure, along with free cash flow to net income conversion rate, are useful to investors in evaluating the Company’s financial performance and measures the Company's ability to generate cash internally to fund Company initiatives. Free cash flow represents net cash provided by operating activities less additions to plant and equipment. Free cash flow is a measurement that is not the same as net cash flow from operating activities per the statement of cash flows and may not be consistent with similarly titled measures used by other companies. A reconciliation of free cash flow to net cash provided by operating activities is included in the press release furnished as Exhibit 99.1.

The Company uses after-tax return on average invested capital ("After-tax ROIC") to measure the effectiveness of its operations' use of invested capital to generate profits. After-tax ROIC is not defined under U.S. generally accepted accounting principles ("GAAP"). After-tax ROIC is a non-GAAP financial measure that the Company believes is a meaningful metric to investors in evaluating the Company's ability to generate returns from cash invested in its operations and may be different than the method used by other companies to calculate After-tax ROIC. The Company defines After-tax ROIC as operating income after taxes divided by average invested capital, which is annualized when presented in interim periods. Operating income after taxes is a non-GAAP measure consisting of net income before interest expense and other income (expense), on an after-tax basis, which are excluded as they do not represent returns generated by the Company's operations. For comparability, the Company also excluded the net discrete tax benefit of $27 million in the third quarter of 2025 from net income and the effective tax rate for the three and nine months ended September 30, 2025. Additionally, for comparability, the Company also excluded the discrete tax benefit of $21 million in the first quarter of 2025 from net income and the effective tax rate for the nine months ended September 30, 2025. Also, for comparability, the Company excluded the net discrete tax benefit of $121 million in the third quarter of 2024 from net income and the effective tax rate for the three and nine months ended September 30, 2024, and for the twelve months ended December 31, 2024. Total invested capital represents the net assets of the Company, other than cash and equivalents and outstanding debt which do not represent capital investment in the Company's operations. The most comparable GAAP measure to operating income after taxes is net income. Calculations of net income to average invested capital and After-tax ROIC are included in the press release furnished as Exhibit 99.1.

The Company presented diluted net income per share for the three months ended September 30, 2024 excluding the impact of the sale of the Company's noncontrolling interest in Wilsonart International Holdings LLC. The Company also presented diluted net income per share for the twelve months ended December 31, 2024 excluding the cumulative effect of a change in inventory accounting method and the impact of the sale of the Company's noncontrolling interest in Wilsonart International Holdings LLC. The Company believes these non-GAAP measures enhance investors' understanding of the Company's underlying financial performance and improves comparability with other periods. A reconciliation of this non-GAAP measure to diluted net income per share is included in the press release furnished as Exhibit 99.1.
