Management also believes that investors regularly rely on non-GAAP financial measures, such as adjusted EBITDA and adjusted earnings per share, to assess operating performance and that such measures may highlight trends in the Company’s business that may not otherwise be apparent when relying on financial measures calculated in accordance with GAAP. While the Company believes these non-GAAP measures are useful in evaluating the Company’s performance, this information should be considered as supplemental in nature and not as a substitute for or superior to the related financial information prepared in accordance with GAAP. Additionally, these non-GAAP financial measures may differ from similar measures presented by other companies.

PUBLIC LENDER PRESENTATION Integration-Lite Combination With Significant Upside Potential 20 Greater investment and increased support to the Precoat team to drive improvements in the organization and accelerate growth✓ Ability to capitalize on shared vision of value-added metal coating solutions and best practices to drive continuous operational improvements✓ Superior processing capabilities and operational flexibility✓ Competitive advantage from strategic footprint with close proximity to customers✓ Strong, centralized back-office and logistics network driving sales and operational efficiencies✓ Runway for profitable expansion and continued margin improvement✓ Opportunity to enhance combined corporate culture and values to bring out the best of both organizations✓ Strong systems and experienced management team at Precoat provide continuity and low integration complexity✓

PUBLIC LENDER PRESENTATION Current Situation / Macro Update Geopolitical Supply Chain / Inflation / Commodity Prices ■ AZZ’s Metal Coatings segment and Precoat are both 100% North America-based, resulting in minimal current disruption from the Russia / Ukraine war and insulation from broader global uncertainty ■ AZZ’s Infrastructure Solutions segment has two European facilities located in the Netherlands and Poland, both of which have not seen any interruption due to the ongoing conflict; AZZ continues to monitor the situation closely ‒ The revenue associated with the two European facilities comprises ~4.4% of AZZ’s pro forma FY2022 sales and ~2.5% of the combined company’s pro forma sales ■ While AZZ and Precoat continue to monitor supply chain related disruptions as well as material and labor inflation, both businesses have been able to expand margins due to short-cycle contracts and purchase orders that allow for agility in pricing as costs rise ■ AZZ’s Metal Coatings segment and Precoat both operate via a tolling model in which customers procure and own the metal, resulting in no direct exposure to movements in steel or aluminum prices ■ Strategic management / pricing and pass-through mechanisms help insulate both businesses from changes in input costs ‒ AZZ stores reserves of zinc, a key galvanizing input, and utilizes fixed price forward contracts to manage purchasing, while preemptively enacting price changes to manage fluctuations in zinc prices ‒ Precoat takes no commodity price risk on coatings by directly passing through paint costs to customers with a markup for processing services, creating an incremental margin opportunity as input costs rise 21 (1) Based on financials as of LTM 2/28/2022 for AZZ and LTM 12/31/2021 for Precoat. AZZ financials include pro forma impact of Steel Creek and DAAM Galvanizing acquisitions. North America 93% International 7% Pro Forma Revenue by Geography(1)

PUBLIC LENDER PRESENTATION Current Situation / Macro Update (Cont’d) COVID-19 ESG ■ AZZ and Precoat are both considered providers of critical infrastructure, so both companies remained open throughout the COVID-19 pandemic ■ AZZ’s Metal Coatings segment was impacted by lower volumes of steel processed in FY2021 due to the economic slowdown, but maintained strong performance due to cost containment measures and saw sales rebound by 13% in FY2022 ■ AZZ’s Infrastructure Solutions segment was more severely impacted in FY2021 due to restrictions on travel and access to customer facilities as well as challenges in key end markets; however, FY2022 backlog is high (+63% vs. FY2021) and demand outlook remains strong ■ Despite a challenging demand environment in 2020, Precoat showed resilient performance and generated both revenue and adjusted EBITDA growth ■ Precoat demonstrated strong performance in 2021 largely driven by increases in volume and price, which is expected to continue in 2022 ■ AZZ remains committed to operating in a sustainable and socially responsible manner, while minimizing the environmental impact of its operations ■ In 2021, AZZ published its inaugural annual ESG Report, representing the initial step in AZZ’s commitment to regularly disclosing ESG performance ■ AZZ closely considered ESG when evaluating Precoat, and Precoat’s prepaint solution offers environmental benefits relative to other coating methods, resulting in less waste, paint usage and energy usage 22

PUBLIC LENDER PRESENTATION AZZ Q4 FY2022 Performance Update Metal Coatings Infrastructure Solutions Consolidated ■ Sales of $225 million, reflecting an increase YoY of $29 million or 14.8%, primarily due to continued strength in the Metal Coatings segment as well as improvements in the Infrastructure Solutions segment ■ Adjusted EBITDA of $38.0 million (16.9% margin), reflecting a ~220 bps margin improvement YoY driven by continued strength in Metal Coatings, supported by continued stronger backlog converting to sales in the Infrastructure Solutions segment, partially offset by $1.8 million impairment charge reversal in the Infrastructure Solutions segment ■ Sales of $128.3 million, reflecting an increase YoY of $22.1 million or 20.9%, due to higher volumes of production during what is normally a seasonally slower period, and higher selling prices as commodity prices for zinc (25% of production costs) have steadily increased. ■ AZZ Surface Technologies, which was impacted more heavily during COVID, returned to profitable operations during FY2022 ■ Adjusted EBITDA of $39.2 million (30.6% margin), reflecting a ~95 bps margin decrease YoY driven by increased commodity prices as well as higher inflationary pressure ■ Sales of $96.4 million, reflecting an increase YoY of $6.9 million or 7.7%, primarily due to higher Industrial sales of $15.5 million as refineries returned to more normal turnaround cadence, and stronger backlog in the Electrical platform, partially offset by $8.2 million lower sales in China ■ Adjusted EBITDA of $11.4 million (11.9% margin), reflecting a ~530 bps margin improvement YoY driven by much stronger backlog in the Electrical platform converting to sales and improved margins as well as stronger turnaround business in the Industrial platform as refineries are returning to normal capacities, partially offset by $1.8 million impairment charge reversal Revenue ($, millions) Adjusted EBITDA Margin (%) Revenue ($, millions) Adjusted EBITDA Margin (%) Revenue ($, millions) Adjusted EBITDA Margin (%) Note: Based on fiscal quarter ended 2/28/2022.
