Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026.

The accompanying Condensed Consolidated Balance Sheet at December 31, 2025 has been derived from the audited financial statements at that date, but does not include all of the information and notes required by GAAP for complete financial statements.

NOTE 2 — REVENUE RECOGNITION

The following table presents the Company’s Net sales disaggregated by product line:

Consumable sales consist of welding, brazing and soldering filler metals. Equipment sales consist of arc welding equipment, laser, plasma and oxyfuel cutting systems, wire feeding systems, fume control equipment, welding accessories, specialty gas regulators, mobile power equipment, wear solutions, software and education solutions. Automation sales consist of a comprehensive portfolio of solutions for joining, cutting, material handling, module assembly, and end of line testing. Consumable and Equipment products are sold within each of the Company’s operating segments. Automation products are sold within the Company’s Americas Welding and International Welding operating segments.

Within the Automation product line, there are certain customer contracts related to automation products that may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines the standalone selling price based on the prices charged to customers or using expected cost plus margin. Approximately 10% of the Company’s consolidated Net sales are recognized over time.

At March 31, 2026, the Company recorded $42,404 related to advance customer payments and $53,660 related to billings in excess of revenue recognized. These contract liabilities are included in Other current liabilities in the Condensed Consolidated Balance Sheets. At December 31, 2025, the balances related to advance customer payments and billings in excess of revenue recognized were $49,451 and $62,778, respectively. Substantially all of the Company’s contract liabilities are recognized within twelve months based on contract duration. The Company records an asset for contracts where it has recognized revenue, but has not yet invoiced the customer for goods or services.

At March 31, 2026 and December 31, 2025, the Company recorded $86,576 and $78,211, respectively, related to these contract assets which are included in Other current assets in the Condensed Consolidated Balance Sheets. Contract asset amounts are expected to be billed within the next twelve months.

The Company’s innovative solutions enable higher quality and productivity across a variety of processes including welding, cutting, brazing, machining, process automation, and field repair.

The Company’s products include arc welding equipment, filler metals (welding, brazing and soldering consumables),cutting systems (laser, plasma and oxyfuel), wire feeding systems, fume control equipment, welding accessories, specialty gas regulators, mobile power equipment, wear solutions, software, and education solutions; as well as a comprehensive portfolio of automated solutions and system integration services for joining, cutting, material

handling, module assembly, and end of line testing. Services include additive manufacturing, precision fabrication, wear services, upfitting, and training.

The Company has aligned its organizational and leadership structure into three operating segments to support growth strategies and enhance the utilization of the Company’s worldwide resources and global sourcing initiatives. The operating segments consist of Americas Welding, International Welding and The Harris Products Group. The Americas Welding segment includes welding operations in North and South America. The International Welding segment includes welding operations in Europe, Africa, Asia and Australia. The Harris Products Group includes the Company’s global cutting, soldering and brazing businesses, specialty gas equipment, as well as its retail business in the United States.

Segment performance is measured and resources are allocated based on a number of factors, the primary measure being the adjusted earnings before interest and income taxes ("Adjusted EBIT") profit measure. Adjusted EBIT is defined as Operating income plus Other income (expense), 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.

The Company’s chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM uses segment Adjusted EBIT to allocate resources for each segment predominantly in establishing the Company’s long-term strategy and in developing the annual budget. The CODM considers actual performance using Adjusted EBIT when making decisions about allocating capital and resources to the segments.

The following tables present Adjusted EBIT by segment and other segment information:

The Company’s derivative contracts are valued at fair value using the market approach. The Company measures the fair value of foreign exchange contracts and net investment contracts using Level 2 inputs based on observable spot and forward rates in active markets.

The deferred compensation liability is the Company’s obligation under its executive deferred compensation plan. The Company measures the fair value of the liability using the market values of the participants’ underlying investment fund elections.

The fair value of Cash and cash equivalents, Accounts receivable, Short-term debt excluding the current portion of Long-term debt and Trade accounts payable approximated book value due to the short-term nature of these instruments at both March 31, 2026 and December 31, 2025.

The Company has various financial instruments, including cash and cash equivalents, short and long-term debt and forward contracts.
