The increase in organic sales for the three months ended June 30, 2026 is driven by an increase in pricing, primarily due to higher input costs, as well as higher volumes. The increase in organic sales for the six months ended June 30, 2026 is driven by an increase in pricing, primarily due to higher input costs. Gross Profit: Gross profit as a percentage of sales decreased 0.5% and 0.6% for the three and six months ended June 30, 2026, respectively, as compared to the same 2025 periods, driven by unfavorable impacts from product mix and higher input costs. This includes last-in, first-out (“LIFO”) charges of $4,186 and $5,024 for the three and six months ended June 30, 2026 and LIFO charges of $8,523 and $10,284 for the three and six months ended June 30, 2025, respectively, which are primarily due to rising input costs. Selling, General & Administrative Expenses: Selling, general & administrative expenses increased in the three and six months ended June 30, 2026 as compared to the same 2025 periods, primarily due to increases in spend related to the Company’s RISE strategic initiatives, acquisitions and the unfavorable impact of foreign currency translation. Selling, general & administrative expenses as a percentage of sales decreased primarily due to higher organic sales. Operating Income: Operating income as a percentage of sales was 18.1% for the three months ended June 30, 2026 as compared to 17.6% in the prior year period. Excluding special items, Operating income as a percentage of sales was 18.4% for the three months ended June 30, 2026 as compared with 17.9% in the prior year period. Operating income as a percentage of sales was 17.4% for the six months ended June 30, 2026 as compared to 17.1% in the prior year period. Excluding special items, Operating income as a percentage of sales was 17.6% in the six months ended June 30, 2026 as compared with 17.4% in the prior year period.

Decrease for the three months ended June 30, 2026 in International Welding is primarily due to slowing industrial activity in Europe and the Middle East conflict. Decrease for the six months ended June 30, 2026 in International Welding is primarily due to slowing industrial activity in Europe, the Middle East conflict and lower project volumes within the automation product line. Decrease for the three and six months ended June 30, 2026 in The Harris Products Group is primarily due to a challenging prior year comparison resulting from expanded market presence in retail. (2) Increase in all segments due to price actions taken in response to higher input costs. (3) Increase in International Welding due to the acquisition discussed in Note 4 to the consolidated financial statements. (4) Increase for the three and six months ended June 30, 2026 for all three segments was primarily attributable to the favorable impact of a stronger U.S. dollar. 27 Table of Contents Segment performance is measured and resources are allocated based on a number of factors, the primary measure being the Adjusted EBIT profit measure. Adjusted EBIT is defined as Operating income plus Other income, adjusted for special items as determined by management such as the impact of rationalization activities, certain asset impairment charges and gains or losses on disposals of assets.

As of June 30, 2026, the Company had $242,443 of cash and cash equivalents on hand and no outstanding borrowings under its $1,047,482 revolving credit facilities. 31 Table of Contents The Company’s capital allocation priorities include internal investment to support existing operations and organic growth, investment in acquisitions to grow the business and then returning capital to shareholders through dividends and share repurchases. The Company’s cash flow from operations can be cyclical. In assessing liquidity, the Company reviews working capital measurements to define areas for improvement. Management anticipates the Company will be able to satisfy cash requirements for its ongoing businesses for the foreseeable future primarily with cash generated by operations, existing cash balances, borrowings under its existing credit facilities and raising debt in capital markets. The Company continues to expand globally and periodically consider acquisitions that would involve significant investments. The Company can fund its global expansion plans with operational cash flow, but a significant acquisition may require access to capital markets, in particular, the long-term debt market, as well as the syndicated bank loan market. The Company’s financing strategy is to fund itself at the lowest after-tax cost of funding. Where possible, the Company utilizes operational cash flows and raises capital in the most efficient market, usually the United States, and then lends funds to the specific subsidiary needing or requiring funding. If additional acquisitions providing appropriate financial benefits become available, additional expenditures may be made.

Return on Invested Capital The Company reviews ROIC in assessing and evaluating the Company’s underlying operating performance. As discussed in the Non-GAAP Financial Measures section above, Adjusted ROIC is a non-GAAP financial measure that the Company believes is a meaningful metric to investors in evaluating the Company’s financial performance. The calculation may be different than the method used by other companies to calculate ROIC. Adjusted ROIC is defined as rolling 12 months of Adjusted net income excluding tax-effected interest income and expense divided by invested capital. Invested capital is defined as total debt, which includes Short-term debt and Long-term debt, less current portions, plus Total equity. 33 Table of Contents The following table presents the reconciliations of ROIC and Adjusted ROIC to net income: ​ \ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Twelve Months Ended June 30, ​ ​ ​ ​ ​ 2026 ​ ​ ​ 2025 Net income as reported ​ $ 553,551 $ 502,868 ​ Plus: Interest expense (after-tax) ​ ​ 44,075 ​ ​ 42,688 ​ Less: Interest income (after-tax) ​ ​ 4,564 ​ ​ 6,636 ​ Net operating profit after taxes ​ $ 593,062 ​ $ 538,920 ​ Special items: ​ ​ ​ ​ ​ ​ ​ Rationalization and asset impairment net charges ​ 17,436 31,172 ​ Transaction costs ​ 2,176 4,332 Pension settlement net charges ​ 719 3,792 ​ Amortization of step up in value of acquired inventories ​ 4,104 4,771 ​ Tax effect of Special items (1) ​ 5,555 (11,118) ​ Adjusted net operating profit after taxes ​ $ 623,052 $ 571,869 ​ ​ ​ ​ ​ ​ ​ Invested Capital ​ ​ ​ June 30, 2026 ​ ​ ​ June 30, 2025 ​ Short-term debt ​ $ — ​ $ 105,323 ​ Long-term debt, less current portion ​ ​ 1,150,054 ​ ​ 1,150,395 ​ Total debt ​ ​ 1,150,054 ​ ​ 1,255,718 ​ Total equity ​ 1,554,180 ​ 1,379,613 ​ Invested capital ​ $ 2,704,234 ​ $ 2,635,331 ​ ​ ​ ​ ​ ​ ​ ​ ​ Return on invested capital as reported ​ 21.9 % 20.4 % Adjusted return on invested capital ​ 23.0 % 21.7 % ​ (1) Includes the net tax impact of Special items recorded during the respective periods.
