ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES	ORGANIZATION AND OPERATIONS AND SUMMARY OF ACCOUNTING POLICIES CSW Industrials, Inc. (the “Company,” “CSW,” “we,” “our” or “us”) is a diversified industrial growth company with a strategic focus on providing niche, value-added products in the end markets we serve. We operate in three business segments: Contractor Solutions, Specialized Reliability Solutions and Engineered Building Solutions. Our products include mechanical products for heating, ventilation, air conditioning and refrigeration ("HVAC/R"), plumbing products, grilles, registers and diffusers, building safety solutions and high-performance specialty lubricants and sealants. End markets that we serve include HVAC/R, architecturally-specified building products, plumbing, general industrial, energy, rail transportation, mining and electrical. Our manufacturing operations are concentrated in the United States (“U.S.”), Vietnam and Canada, and we have distribution operations in the U.S., Australia, Canada and the United Kingdom (“U.K.”). Our products are sold directly to end users or through designated channels in over 100 countries around the world, primarily including the U.S., Canada, the U.K. and Australia. Drawing on our innovative and proven technologies, we seek to deliver solutions primarily to contractors that place a premium on superior performance and reliability. We believe our brands are well-known in the specific end markets we serve and have a reputation for high quality. We rely on both organic growth and inorganic growth through acquisitions to provide an increasingly broad portfolio of performance optimizing solutions that meet our customers’ ever-changing needs. We have a successful record of making attractive, synergistic acquisitions in support of this objective, and we remain focused on identifying additional acquisition opportunities in our core end markets. Many of our products are used to protect the capital assets of our customers that are expensive to repair or replace and are critical to their operations. We have a source of recurring revenue from the maintenance, repair and overhaul and consumable nature of many of our products. We also provide some custom engineered products that strengthen and enhance our customer relationships. The reputation of our product portfolio is built on more than 100 well-respected brand names, such as AC Guard®, Air Sentry®, Amrad®, Aspen ManufacturingTM, Balco®, Cover Guard®, Deacon®, Duckt-Strip®, Dust Free®, Falcon®, Greco®, Hydrotex®, Jet-Lube®, Kopr-Kote®, Leak Freeze®, MARS®, Metacaulk®, No. 5®, OilSafe®, PF WaterWorksTM, ProAction Fluids®, PSP ProductsTM, RectorSeal®, Safe-T-Switch®, Shoemaker Manufacturing®, Smoke Guard®, TRUaire® and Whitmore®. The ongoing conflict in the Middle East, including active military operations in Iran that began February 28, 2026, has contributed to disruptions in global shipping lanes, particularly through the Strait of Hormuz and the broader Persian Gulf region. While we do not source materials directly from Iran or the Persian Gulf region, the conflict has contributed to elevated crude oil prices, ocean and domestic freight and certain commodity costs, and it has extended lead times from Asian suppliers as carriers reroute through alternative passages including the Cape of Good Hope. We are continuing to work with our logistics partners to mitigate these impacts and do not currently believe they will have a material adverse effect on our ability to meet customer demand, though we continue to monitor the situation closely. Basis of Presentation The consolidated financial statements included in this Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026 (“Quarterly Report”), include all revenues, costs, assets and liabilities directly attributable to CSW and have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements are for us and our consolidated subsidiaries, each of which is a wholly-owned subsidiary, except our non-controlling 50% investment in a variable interest entity (“VIE”) for which we have determined that we are the primary beneficiary and therefore have consolidated into our financial statements. All significant intercompany transactions have been eliminated in consolidation. The consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary to present a fair statement of CSW’s financial position as of June 30, 2026, and the results of operations for the three month periods ended June 30, 2026 and 2025. All adjustments are of a normal, recurring nature. The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. These consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto included in CSW’s Annual Report on Form 10-K for the fiscal year ended March 31, 2026 (the “Annual Report”). Accounting Policies We have consistently applied the accounting policies described in our Annual Report in preparing these consolidated financial statements. Accounting Developments Pronouncements not yet implemented In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. This ASU provides guidance to expand disclosures related to the disaggregation of income statement expenses. Also, this ASU requires, in the notes to the financial statements, disclosure of specified information about certain costs and expenses which includes purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense caption. ASU 2025-01 is effective for fiscal years beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, on a retrospective or prospective basis, with early adoption permitted. This ASU will be effective for our Form 10-K for fiscal 2028 and our Form 10-Q for the first quarter of 2029. We are currently evaluating the impact this ASU may have on our financial statement disclosures. In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements, which includes amendments to more closely align hedge accounting with the economics of an entity’s risk management activities. ASU 2025-09 is effective for fiscal years beginning after December 15, 2027 with early adoption permitted should be applied prospectively. The amendments will be effective for our Form 10-K for fiscal 2029 and our Form 10-Q for the first quarter of 2029. We are currently evaluating the impact this ASU may have on our financial statement disclosures. In December 2025, the FASB issued ASU 2025-11 to amend the guidance in Interim Reporting (Topic 270): Narrow-Scope Improvements. The update provides clarifications intended to improve the consistency and usability of interim disclosure requirements, including a comprehensive listing of required interim disclosures and a new disclosure principle for reporting material events occurring after the most recent annual period. The amendments do not change the underlying objectives of interim reporting but are designed to enhance clarity in application. The guidance is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years. This ASU will be effective for our Form 10-K for fiscal 2029 and our Form 10-Q for the first quarter of 2029. We are currently evaluating the impact this ASU may have on our financial statement disclosures. In December 2025, the FASB issued ASU 2025-12 Codification Improvements to address suggestions received from stakeholders on the Accounting Standards Codification and to make other incremental improvements to U.S. GAAP. The update represents changes to the Codification that (1) clarify, (2) correct errors, or (3) make minor improvements. The amendments make the Codification easier to understand and apply. The guidance is effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years. This ASU will be effective for our Form 10-K for fiscal 2028 and our Form 10-Q for the first quarter of 2028. We do not expect the adoption to have a material impact on our financial statement disclosures.
