Business segments and activities
The Automotive OEM segment sells vehicle components. The Food Equipment segment sells commercial kitchen appliances. The Test & Measurement and Electronics segment sells inspection and analysis equipment. The Welding segment sells welding equipment and consumables, and includes businesses such as Miller Electric Mfg. LLC, which is described as a leading worldwide manufacturer of Miller brand arc welding products and a wholly owned subsidiary of Illinois Tool Works Inc.
The Polymers & Fluids segment sells industrial and consumer adhesives, solvents, and coatings. The Construction Products segment sells building fasteners and tools. The Specialty Products segment sells products in areas that include medical, packaging, HVAC, and airport ground equipment.
Scale and portfolio characteristics
In its investor communications, ITW reports that it generated revenue of $15.9 billion in 2024 and describes its portfolio as diversified across its seven segments. The company highlights that its segments operate in markets where it sees demand for highly innovative, customer-focused solutions. ITW also notes that its colleagues work within a decentralized and entrepreneurial culture.
Segment data disclosed for 2025 shows that revenue and operating income are distributed across all seven segments, with each segment reporting positive operating margins. For example, in the third quarter of 2025, ITW reported revenue contributions from Automotive OEM, Food Equipment, Test & Measurement and Electronics, Welding, Polymers & Fluids, Construction Products, and Specialty Products, with segment operating margins ranging from the low twenties to the low thirties in percentage terms.
Welding and related products
Within the Welding segment, Miller Electric Mfg. LLC illustrates the type of businesses ITW owns. Miller is described as a leading worldwide manufacturer of Miller brand arc welding products and is headquartered in Appleton, Wisconsin. Recent announcements from Miller under ITW ownership include ArcCapture weld camera systems for educational and automated welding environments, the Multimatic 215 PRO multiprocess welder, the Millermatic 211 PRO MIG welder, and personal protective equipment such as a women’s PPE line and graphic welding helmets.
These products, as described in Miller press releases, are aimed at professional, educational, and industrial users and are positioned around factors such as training effectiveness, process control, flexibility across welding processes, and user comfort. Miller’s communications also reference the Hercules welding technology, which ITW first introduced in 2022 and which is engineered for high-deposition MIG welding in heavy fabrication and fixed automation environments.
Financial reporting and metrics
Illinois Tool Works regularly reports its financial results, including revenue, operating income, operating margin, and cash flow metrics. For the third quarter of 2025, ITW reported operating revenue, operating income, and operating margin at the total company level, along with segment-level revenue and operating margin data. The company also discusses non-GAAP financial measures such as free cash flow and after-tax return on average invested capital (After-tax ROIC), explaining how these are calculated and why it believes they are useful in evaluating its operations.
ITW’s public filings describe free cash flow as net cash provided by operating activities less additions to plant and equipment, and indicate that this measure is used to assess cash available for dividends, share repurchases, acquisitions, and debt repayment. After-tax ROIC is defined as operating income after taxes divided by average invested capital, with adjustments described in the company’s filings for discrete tax items when presented.
Dividends and capital allocation
The company’s board of directors periodically declares dividends on ITW common stock. For example, the board declared a dividend for the fourth quarter of 2025 and noted that the full-year dividend payout per share represented an increase compared to the prior year. In its third quarter 2025 earnings release, ITW also referenced share repurchases during the quarter and commented on its free cash flow and free cash flow to net income conversion rate.
ITW’s communications emphasize the role of its business model and diversified portfolio in supporting what it describes as solid growth, margins, and returns. The company has also highlighted its history of increasing dividends over many consecutive years, as noted in its third quarter 2025 results release.
