Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	22. 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. Our prior-owned affiliate ₋ The Calvert Company entered into a series of commercial contracts in 2011 and 2015 to provide equipment and services to a power plant in Georgia. The general contractor on the project, WECTEC (a subsidiary of Westinghouse), filed bankruptcy in New York in March of 2017. Our affiliate continued to perform work on the project for the owners/licensee under an interim bridge contract. We believe the affiliate was eventually terminated for convenience on the project, and the affiliate filed an adversary proceeding in bankruptcy court against WECTEC and the owners to collect all unpaid amounts. The owners of the Georgia power plant filed a countersuit in April of 2018. In connection with AZZ selling the majority interest in the AIS business to Fernweh AIS Acquisition LP on September 30, 2022, we agreed to retain this lawsuit. After a long and protracted discovery process and motion practice, we determined in the quarter ended August 30, 2023 that the most favorable outcome to the Company to resolve the dispute may be a negotiated settlement. This decision was made in consideration of the expenses of a lengthy jury trial and potentially protracted appeal process; the resources necessary to continue the prosecution and defense of the case given the size of the discovery and the number of issues involved; the risk factors typically associated with jury verdicts in light of all of the political circumstances currently present in Georgia regarding the power plant; and the benefit of resolving a dispute whose genesis arose more than twelve years ago based solely upon risk avoidance, and not upon the merits of the case. During the third quarter of fiscal 2024, all of the parties entered into a confidential settlement agreement, with no parties admitting any guilt or negligence and AZZ agreed to pay the owners/licensee $5.8 million on or around January 15, 2024 to resolve all outstanding matters related to the dispute. In addition, the agreement included the forgiveness of AZZ's receivable from WECTEC of $3.7 million, which was fully reserved by AZZ. This settlement of $5.8 million was accrued during the second quarter of fiscal year 2024, and is included in "Selling, general and administrative" expense in the consolidated statement of operations for the year ended February 29, 2024. The settlement was included in the AZZ Infrastructure Solutions segment, and the settlement payment was made in the fourth quarter of fiscal year 2024. 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. On May 23, 2024, AZZ 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 up to 30 days to file a motion for reconsideration in the Beaumont Court of Appeals, and up to 45 days to file a petition for review in the Supreme Court of Texas. As of February 28, 2026 and 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 for STI to appeal the Court of Appeals' ruling to the Supreme Court of Texas has expired or the Supreme Court has declined to review the case if requested by STI, whichever scenario is applicable. In 2019, Tampa Electric Company ("TECO") entered into a contract to provide services in Florida. TECO terminated our affiliate from the project, alleging failure to comply with safety guidelines. We believe the affiliate was terminated for convenience on the project, and our affiliate was not given its contractual right of notice and 47 hours to deliver a corrective action plan. In 2020, we filed a lawsuit against TECO for breach of contract and unjust enrichment in the Thirteenth Judicial Circuit Court in and for Hillsborough County, Florida. In connection with AZZ selling the majority interest in the AIS business to Fernweh Group on September 30, 2022, we agreed to retain this lawsuit. The parties unsuccessfully mediated the case in June 2023. The case went to trial on January 13, 2025. On February 10, 2025, the jury rendered a verdict in favor of TECO against our affiliate in the amount of $5.2 million, which represented the receivable due from the TECO, net of allowance. We recognized expense of $6.5 million in the fourth quarter of fiscal 2025, consisting of $5.2 million for the derecognition of the net receivable from TECO and $1.3 million for estimated legal fees, of which $1.2 million was paid during the year ended February 28, 2026. Prior to AZZ's acquisition of Precoat Metals on May 13, 2022, Precoat Metals sold its Armorel Arkansas facility to Nucor Coatings Corporation ("Nucor") via a purchase agreement dated October 27, 2020 ("2020 Agreement"). Nucor subsequently filed a lawsuit against Precoat Metals for indemnification for breach of environmental representations and warranties made in the 2020 Agreement. In the lawsuit, Nucor asserted that it has sustained certain damages resulting from Precoat Metal’s breach of its indemnification obligations that were set forth in the 2020 Agreement. The parties attended a mediation on March 18, 2024, and although the Company believed Nucor’s case was deficient and it had very strong defenses to the allegations asserted by Nucor, management determined that it was still in the best interest of the Company to settle all matters for the estimated cost of defense to retain commercial relationships with Nucor, who is both a customer and supplier to the Company. The parties mutually agreed to resolve disputed matters for $5.25 million. The parties are currently preparing a definitive settlement agreement which will resolve all outstanding matters related to the dispute. The $5.25 million settlement amount and additional legal expense of $0.5 million was recognized during the fourth quarter of fiscal year 2024, and is included in "Selling, general and administrative" expense in the consolidated statement of operations for the year ended February 29, 2024. The settlement amount was paid by the Company to Nucor on September 9, 2024. On July 29, 2024, Gainesville Associates, LLC ("Gainesville Associates") filed a complaint (the "Complaint") in the Circuit Court of Prince William County, Virginia against AZZ, Atlantic Research, LLC ("ARC"), Precoat Metals Corporation, and Chromalloy Corporation (collectively "Defendants"), asserting claims for breach of contract against ARC and unjust enrichment against all Defendants. The Complaint arose out of a lease, dated January 1, 1976, between Gainesville Associates as landlord and ARC as tenant (as subsequently amended in 1982, 2012, 2013 and 2017, the "Lease") for property in Gainesville, Virginia (the "Property"). ARC ceased using the property in 2005 after which point ARC remained in the Lease to complete its obligations on the property pursuant to a consent decree entered into between the U.S. Environmental Protection Agency ("EPA") and ARC in 1992. ARC satisfied its obligations under the consent decree in 2018 (other than ongoing well water monitoring and testing) and terminated the Lease in 2019. In its Complaint, Gainesville Associates alleged that ARC breached certain provisions of the Lease. On September 3, 2024, Defendants removed the action to the United States District Court of the Eastern District of Virginia. On September 24, 2024, Defendants filed a motion to dismiss the Complaint. On October 30, 2024, the claim was denied and the court ordered the parties to mediate. The parties attended the court ordered mediation on December 3, 2024, and although the Company believed the Gainesville Associates' case was deficient and it had very strong defenses to the allegations asserted by Gainesville Associates, management determined that it was still in the best financial interest of the Company to settle all matters for the estimated cost of defense. The parties mutually agreed to resolve all disputed matters for $6.0 million, of which our portion was $1.9 million. For the year ended February 28, 2025, we recognized $1.6 million for legal expenses and $1.9 million for our portion of the settlement amount. The settlement amount was paid on January 10, 2025. Environmental As of February 28, 2026, the reserve balance for our environmental liabilities was $17.6 million, of which $1.1 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. Commodity pricing As of February 28, 2026, we had non-cancelable forward contracts to purchase approximately $97.1 million of zinc and $7.3 million of natural gas at various volumes and prices. All such contracts expire in fiscal 2027. Other As of February 28, 2026, we had outstanding letters of credit in the amount of $12.0 million. These standby letters of credit are primarily issued to support insurance deductibles and other collateral requirements. In addition, as of February 28, 2026, a warranty reserve in the amount of $4.8 million was established to offset any future warranty claims. We have expanded our coatings capabilities through the construction of a new 25-acre aluminum coil coating facility in Washington, Missouri, which became operational during the first quarter of fiscal 2026. The new greenfield facility is included in the AZZ Precoat Metals segment and is supported by a take-or-pay contract for approximately 75% of the output from the new plant. We expect to spend approximately $122.8 million in capital payments related to the project, of which $113.6 million was paid prior to fiscal 2026 and approximately $7.8 million was paid during year ended February 28, 2026. The remaining balance of $1.4 million is expected to be paid in the first quarter of fiscal 2027.
