INVESTOR PRESENTATION ■ The North American Hot-Dip Galvanizing Market is estimated to be a ~$2 billion industry with growth rates similar to GDP. ■ The Hot-Dip market serves a diverse set of end markets and is benefitting from positive trends in key end markets, including a broader set of customers that galvanize fabricated products due to its superior corrosion protection, and overall increased infrastructure spending in North America ■ The Hot-Dip galvanizing market penetration in North America is ~33%, whereas in Europe it is more developed at ~+50%; North America has an opportunity to grow to similar penetration rates North American Hot-Dip Galvanizing Market Commentary U.S. End Market Breakdown Post-Fabrication Hot-Dip Galvanizing is a subset of the overall metal coatings materials market which protects steel structures from corrosion, using zinc, a environmentally friendly infinitely reusable material AZZ’s industry-leading footprint and proximity to metal fabricators is a key competitive advantage U.S. Hot-Dip Galvanizing Market U.S. Regional Breakdown AZZ is the clear leader in hot-dip galvanizing, and has industry-leading margins due to focus on operations improvement, customer service and pricing Diversity of demand, and growth/investment in infrastructure will drive demand for galvanizing Industrial 25% Construction 26% Electrical & Telecommunication 15% OEM's 15% Bridge & Highway 6% Petrochemical 3% Agriculture 6% Recreation 4% Sales AZZ, 41 Valmont, 19 V&S, 8 South Atlantic, 9 Metalplate, 7 Monnig, 5 Corbec, 4 ZincPower, 4 Others, 78 Competitor Landscape; # of plants Southeast, 12% Central, 24% Southwest, 20% Northeast, 21% Texas, 23% Sales by Region 16

Operating Overview 17

INVESTOR 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 no disruption/exposure from the Russia / Ukraine war, and insulated from broader global uncertainty ■ 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 while also offering a wide range of value-added services that are independent of the base processes ‒ 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 18

INVESTOR 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 ■ 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 pre-paint solution offers environmental benefits relative to other coating methods, resulting in less waste, paint usage and energy usage 19
