Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	18. Commitments and Contingencies Legal AZZ and its subsidiaries are named defendants and plaintiffs in various routine lawsuits incidental to our business. These proceedings include labor and employment claims, various commercial disputes, worker’s compensation and environmental matters, all arising in the normal course of business. As discovery progresses on all outstanding legal matters, we continuously evaluate opportunities to either mediate the cases or settle the disputes for nuisance value or the cost of litigation as a way to resolve the disputes prior to trial. As the pending cases progress through additional discovery and potential mediation, our assessment of the likelihood of a favorable or an unfavorable outcome on the pending lawsuits may change. The actual outcome of these lawsuits or other proceedings cannot be predicted with any certainty, and the amount of any potential liability that could arise with respect to such lawsuits or other matters cannot be predicted at this time. Therefore, management, after consultation with legal counsel believes it has strong claims or defenses to all of its legal matters and does not expect liabilities, if any, from these claims or proceedings, either individually or in the aggregate, to have a material effect on the Company’s financial position, results of operations or cash flows. In 2017, Southeast Texas Industries, Inc. ("STI") filed a breach of contract lawsuit against the Company in the 1st District Court of Jasper County, Texas (the "Court"). In 2020, we filed a counter suit against STI for amounts due to AZZ Beaumont for work performed. On October 16, 2023, the case went to trial, and on October 27, 2023, the jury rendered a verdict in favor of STI and against AZZ in the amount of $4.5 million in damages for breach of contract and breach of express warranty. On February 14, 2024, the trial court entered Final Judgment in favor of STI, awarding STI actual damages of $4.5 million, plus $1.0 million in attorney fees. On May 14, 2024, we filed a Notice of Appeal in the Court of Appeals for the Ninth district of Texas in Beaumont. AZZ has purchased a supersedeas bond to cover the final judgment amount during the appellate process. We filed our appellate brief on February 24, 2025. Oral arguments were presented by the parties to the Court of Appeals on March 5, 2026. On April 9, 2026, the Beaumont Court of Appeals ruled there was insufficient evidence to support the final judgment against AZZ, and that STI shall take nothing from AZZ. STI has until June 26, 2026 to file a petition for review in the Supreme Court of Texas. As of the date of this filing, we still have a legal accrual of $5.5 million recorded, which is included in "Other accrued liabilities" on our consolidated balance sheets. This legal accrual will remain in place until the time the Supreme Court of Texas has declined to review the case as requested by STI, or makes a ruling on STI's petition on the merits, whichever scenario is applicable. On May 1, 2026, Kaiser Aluminum Warrick LLC ("Kaiser") filed a complaint against Precoat Mezzanine LLC ("Precoat"), an indirectly held subsidiary of AZZ Inc., in the Superior Court for the State of Delaware alleging breach of contract and breach of express warranty, and seeking declaratory judgment. Kaiser has asserted that Precoat failed to fulfill its obligations under a Master Agreement for Procurement of Services entered into on October 9, 2024. This matter is in its early stages, and we are unable to estimate a range of possible loss, if any, at this time. The Company, in consultation with its legal counsel, intends to vigorously defend this lawsuit, including the assertion of counterclaims. Environmental As of May 31, 2026, the reserve balance for our environmental liabilities was $17.4 million, of which $2.0 million is classified as current. Environmental remediation liabilities include costs directly associated with site investigation and site remediation, such as materials, external contractor costs, legal and consulting expenses and incremental internal costs directly related to ongoing remediation plans. Estimates used to record environmental remediation liabilities are based on the Company's best estimate of probable future costs based on site-specific facts and circumstances known at the time of these estimates and they are updated on a quarterly basis. Estimates of the cost for the potential or ongoing remediation plans are developed using internal resources and third-party environmental engineers and consultants. We accrue the anticipated cost of environmental remediation when the obligation is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. While any revisions to our environmental remediation liabilities could potentially be material to the operating results of any fiscal quarter or fiscal year, we do not expect such additional remediation expenses to have an adverse material effect on our financial position, results of operations, or cash flows.
