**Conflict Minerals Report**

**For The Year Ended December 31, 2025**

This Conflict Minerals Report (this "Report") of AZZ Inc. (the "Company", "our" or "we") has been prepared pursuant to Rule 13p-1 and Form SD ("the Conflict Minerals Rule" or "the Rule") promulgated under the Securities and Exchange Act of 1934, as amended, for the reporting period from January 1, 2025 to December 31, 2025.

**Company Overview**

The Company was established in 1956 and incorporated under the laws of the state of Texas. We are a provider of hot-dip galvanizing and coil coating solutions to a broad range of end-markets, predominantly in North America.

During calendar year 2025, we had two distinct operating segments: the Metal Coatings segment and the Precoat Metals segment. The Metal Coatings segment is a leading provider of metal finishing solutions for corrosion protection, including hot-dip galvanizing, spin galvanizing, powder coating, anodizing and plating to the North American steel fabrication and other industries. The Precoat Metals segment provides aesthetic and corrosion protective coatings and related value-added services for steel and aluminum coils, primarily serving the construction; appliance; heating, ventilation, and air conditioning (HVAC); container; transportation and other end markets in the United States.

**The Conflict Minerals Rule**

Rule 13p-1 was adopted by the SEC to implement reporting and disclosure requirements related to conflict minerals as directed by the Dodd-Frank Wall Street Reform Act of 2010 ("Dodd-Frank"). The Rule imposes certain reporting obligations on SEC registrants whose manufactured products contain conflict minerals that are necessary to their functionality or production. The term "conflict minerals" is defined in Section 13(p) as (A) cassiterite, columbite-tantalite (coltan), gold, wolframite, and their derivatives, as limited by the Rule, tin, tantalum, tungsten, and gold ("3TGs" or "conflict minerals"); or (B) any other mineral or its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of Congo ("DRC") or any adjoining country that shares an internationally recognized border with the DRC.

The Rule provides for a three-step disclosure process. The first step is to determine whether the Rule applies (i.e., a company must determine whether its manufactured products contain 3TG that subject it to the requirements of section 1502 of Dodd-Frank). The second step is to conduct a "reasonable country of origin inquiry" ("RCOI") to determine whether any of the 3TG in its products originated in the Democratic Republic of Congo or an adjoining country (the "covered countries") and are not from recycled or scrap sources. Following the RCOI process, if the company has reason to believe that the 3TG in its products may have originated in the covered countries and did not come from scrap or recycled sources, it must move on to the third step, which is to conduct due diligence in an attempt to establish whether the sourcing of the 3TG could have provided funding for armed groups in the

------

covered countries. Companies requiring due diligence must use a nationally or internationally recognized standard in order to meet their compliance and reporting obligations and file a Conflict Minerals Report ("CMR") with the SEC that includes a description of those due diligence measures.

We remain committed to complying with the requirements of the Rule and upholding responsible sourcing practices. As such, the Company has put into place a due diligence program to address human rights issues and responsible practices across its supply chain.

**Due Diligence Measures Performed**

We are a downstream consumer– we do not purchase raw or smelted ores and our Company is several supply–chain layers removed from the mining and processing of 3TG metals. Accordingly, we relied heavily on our direct suppliers to complete our RCOI for calendar year 2025.

Our due diligence measures were designed to be in conformity with the criteria set forth in the internationally-recognized OECD Guidance, as set forth below.

***Step 1: Establish and Maintain Strong Company Management Systems***

We've taken the following measures to establish an internal management system to support supply- chain due diligence:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Assembled an internal, cross-functional team to oversee the Company's conflict minerals compliance program. The team reports to the Chief Legal Officer and includes representatives from the Company's corporate team and our relevant business segments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adopted a conflict minerals policy and posted the policy on the Company's website.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Documented the process the Company follows to collect information from direct suppliers regarding the use and origin of the 3TGs in its supply chain and made risk-based sourcing decisions based on that information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Communicated that the Company's ethics hotline – AZZ Alertline (https://azz.alertline.com)

can be used to report concerns regarding compliance with the Rule.

***Step 2: Identify and Assess Risks in Supply Chain***

AZZ is a downstream consumer – we do not purchase raw or smelted ores and are several supply-chain layers removed from the mining and processing of these metals. Accordingly, we relied on the participation of our direct suppliers to perform our reasonable country of origin inquiry for calendar year 2025.

------

The RCOI process consisted of several steps. First, we determined internally which products or components could possibly contain 3TGs based on a review of each segment's product lines. Next, we identified the suppliers to those business units of products or components likely to contain 3TG and we surveyed those suppliers using the Conflict Minerals Reporting Template ("CMRT") developed by the Electronic Industry Citizenship Coalition – Global eSustainability Initiative ("EICC/GeSI"). The CMRT is a standardized reporting template that facilitates the transfer of information through the supply chain regarding mineral country of origin and the smelters and refiners being utilized. We provided our suppliers instructions on how to complete the CMRT and asked them to return the completed template to the Company by a certain date.

The Company then reviewed the suppliers' responses for completeness, followed-up on non-responses, and reported on the survey results to senior management. We had a small number of Respondents indicate they do supply products containing 3TGs. However, after further diligence we were not able to identify any products purchased by the Company from these Respondents that were reported to contain 3TGs

***Step 3: Design and implement a strategy to respond to identified risks***

Based on the due diligence efforts described above and information provided by suppliers, the Company does not have reason to believe that the 3TGs contained in its products, if any, financed or benefited armed groups in the Democratic Republic of Congo or adjoining countries. However, due to reliance on supplier-provided information, including non-responses and company-level disclosures, the Company cannot definitively determine the origin of all 3TGs that may be present in its supply chain.

The primary risk identified relates to suppliers that did not respond or provided incomplete information. The Company will continue to enhance supplier engagement, improve contact data, and follow up with suppliers in an effort to mitigate this risk in future reporting periods.

***Step 4: Carry out an independent third-party audit of smelter/refiner due diligence practices***

The Company supports the mission of CFSI's Conflict-Free Smelter Program ("CFSP"), an assessment scheme that facilitates independent third-party audits of smelters and refiners. As a downstream consumer of conflict minerals, however, the Company is not required by the OECD guidelines to directly audit the smelters/refiners in its supply chain.

The Company does not have a direct relationship with any 3TGs smelters or refiners and does not perform or direct audits of these entities within its supply chain. Instead, the Company relies on third party audits of smelters and refiners conducted as part of the RMAP, which uses independent private sector auditors to audit the source, including the mines of origin, and the chain of custody of the conflict minerals used by smelters and refiners that agree to participate in the program.

------

***Step 5: Report annually on supply chain due diligence***

The AZZ Conflict Minerals Policy Statement, Conflict Minerals Report, and the associated Form SD are all made available online at **www.azz.com.** The website (and information accessible through it) is not incorporated into this 2025 Conflict Minerals Report or the associated Form SD.

**Results of Due Diligence**

We received responses from approximately seventy-three percent (73%) of our surveyed suppliers (the "Respondents"). We reviewed the responses against criteria developed to determine which responses required further engagement with the Respondents. These criteria included untimely or incomplete responses as well as inconsistencies within the data reported in the CMRT. The Respondents' responses provided data at a company, user-defined or product level. Seventy-seven percent (77%) of the Respondents' responses provided representations that their products do not contain 3TGs.

Due diligence is ongoing, and the information received continues to improve in quantity and quality. We cannot definitively determine whether any of the 3TGs reported by the suppliers were contained in materials supplied to us or validate that any of these smelters or refiners are actually in our supply chain. While many of the smelters and refiners in our supply chain have been verified to be conflict-free, we were unable to establish the conflict status on all of our products.

**Continuous Risk Mitigation Efforts**

The Company intends to continue to comply with the Rule on an annual basis and expand or narrow the scope of future due diligence efforts in light of any changes in its supply chain. The Company also intends to continuously implement steps that could improve the information gathered from its annual due diligence process, including taking actions designed to increase the response rate of its suppliers. Additionally, the Company intends to take the following steps to mitigate the risk that any 3TGs that may be contained in its products could benefit armed groups during the next reporting period:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continue to improve the number and quality of supplier responses through active supplier engagement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continue to streamline the Company's internal reporting processes.

As the Company has not elected to describe any of its products as "DRC conflict free," this Report has not been subject to an independent private sector audit, consistent with the guidance provided by the SEC in its *Statement on the Effect of the Recent Court of Appeals Decision on the Conflict Minerals Rule* issued on April 29, 2014, the SEC's Order Issuing Stay, dated May 2, 2014, and the SEC's
