Quarterly Results 1Q25 Gerdau S.A. 3<br>MESSAGE FROM MANAGEMENT<br>On January 16, Gerdau celebrated 124 years of history. Throughout its history, Gerdau has become a benchmark in delivering innovative<br>products, solutions, and services, meeting its customers’ needs and creating value for all stakeholders. We believe in shaping the future<br>by connecting our products to the evolving demands of the steel value chain, combining sustainable growth with a strong commitment<br>to being part of the solutions to society's challenges.<br>Regarding operating and financial results, despite a challenging and volatile macroeconomic scenario, we ended 1Q25 with an Adjusted<br>EBITDA of R$2.4 billion, in line with 4Q24. This result was primarily driven by enhanced performance of North America operations,<br>which mitigated the decline in Brazil’s operating results. It is imperative to reiterate the significance of the Company's geographical<br>diversification, particularly during periods of greater market volatility.<br>The North America Segment (which as of 1Q25 includes the special steel operation in the United States) ended the quarter with<br>shipment volumes 14.7% higher than in 4Q24. This growth is partly due to the typical seasonal upturn, but also to the reaction of<br>customers to changes in US trade policy. The reapplication of Section 232 tariffs has led to a significant increase in demand, due to a<br>rebalancing of supply and stocking within the sector. In addition, we saw greater demand for higher value-added products, leading to<br>improved sales mix in the period. Despite the still uncertain scenario regarding the US economy, we saw our order backlog rise, ending<br>the quarter above 70 days, the highest level since 2022.<br>In the Brazil Segment (which as of 1Q25 also includes the special steel operation in this country), we ended the quarter with stable<br>shipment volumes compared to 4Q24. This result was a reflection of lower flat steel shipments in the domestic market due to the<br>scheduled shutdown anticipating the inauguration of the expansion of the hot-rolled coil mill in Ouro Branco (MG), offset by the recovery<br>in long steel volumes. The import penetration rate remained at high levels, ending 1Q25 at 22.0%, 3.7 p.p. higher than 1Q24, further<br>intensifying unfair competition in the domestic market.<br>In the South America Segment, the 1Q25 result came lower than in 4Q24, influenced by lower shipment volumes in Peru and reduced<br>prices in Argentina (due to still weak demand in the domestic market and greater availability of imported steel in the country). In<br>Uruguay, the interruption of public works may begin to affect steel demand.<br>We invested R$1.4 billion in CAPEX in 1Q25, approximately 70% of which was allocated to Brazil. We highlight the significant advance<br>on the Itabiritos Project to expand the Miguel Burnier Mine in Ouro Preto (MG), which ended 1Q25 with 65% physical advance. In addition,<br>we took another step on the journey to producing value-added steel in Brazil by launching the expansion of the hot-rolled coil mill at<br>the Ouro Branco (MG) industrial unit. With the new rolling mill start-up, we will have additional capacity of 250,000 tonnes of hot coils<br>to serve the domestic market, as well as enhance our operational efficiency.<br>Based on the 1Q25 results, we approved the distribution of dividends in the amount of R$0.12 per share, totaling R$243.5 million. In<br>addition, we are consistently executing the share buyback program, approved on January 20, 2025, in which we repurchased 9.4 million<br>shares (GGBR3, GGBR4 and/or GGB) in 1Q25, approximately 15% of the total program and 0.5% of the Company's outstanding shares.<br>Once again, we would like to thank our employees, customers, suppliers, partners, shareholders and other stakeholders for their trust<br>and supportin building our history and continuously creating value.<br>THE MANAGEMENT<br>“I would like to highlight the completion of the expansion of the hot-rolled coil mill in Ouro Branco,<br>launched in March, which aims at enhancing our competitiveness and has the potential to generate<br>incremental annual EBITDA of nearly R$400 million”.<br>Rafael Japur, Gerdau’s CFO and IRO

Quarterly Results 1Q25 Gerdau S.A. 4<br>CONSOLIDATED RESULTS<br>OPERATING PERFORMANCE<br>PRODUCTION & SHIPMENTS<br>CONSOLIDATED 1Q25 4Q24 ∆ 1Q24 ∆<br>Volumes (1,000 tonnes)<br>Crude steel production 2,985 2,718 9.8% 3,090 -3.4%<br>Shipments of steel 2,858 2,719 5.1% 2,724 4.9%<br>The first quarter of 2025 was marked by greater volatility in the markets, due to the challenging environment between steel supply and<br>demand and the unfolding of the United States' tariff policy. Amid a series of uncertainties surrounding the dynamics of global trade,<br>the steel industry continues to be pressured by overcapacity, especially from China, whose surplus production is being allocated to<br>other markets.<br>According to the Brazil Steel Institute (IABR, in Portuguese), apparent demand for steel in Brazil remained robust in the first three<br>months of the year, while the steel supply, driven mainly by imports, remained high. The imported steel penetration rate reached 22.0%<br>in 1Q25, still well above the historical average, which heated up unfair competition in the local market.<br>In the United States, higher demand compared to 4Q24 is partly due to the typical seasonal upturn, but also customers' reaction to<br>changes in US trade policy, increasing inventory levels and favoring the purchase of domestically produced steel. President Trump's<br>announcements in recent months have had a positive impact on steel demand in the short term.<br>In 1Q25, the Company’s crude steel production came 9.8% higher than in 4Q24, driven by the seasonal upturn in the period. Year-over-year, production came 3.4% lower due to scheduled shutdowns at Gerdau industrial units. The utilization of crude steel production<br>capacity was 76% in 1Q25, up 7 p.p. from 4Q24 and down 1 p.p. from 1Q24. Steel shipments totaled 2.9 million tonnes in 1Q25, up 5.1%<br>and up 4.9% from 4Q24 and 1Q24, respectively, boosted by higher volumes in North America in both comparisons.<br>STEEL SHIPMENTS BY SEGMENT<br>BRAZIL NORTH AMERICA SOUTH AMERICA

Quarterly Results 1Q25 Gerdau S.A. 5<br>FINANCIAL PERFORMANCE<br>GROSS PROFIT<br>Net sales totaled R$17.4 billion in 1Q25, up 3.3% from 4Q24, fueled by higher shipment volume in North America. Year-over-year, Net<br>sales grew 7.2%, mainly bolstered by the U.S. dollar appreciation against Brazilian real (+18.2%) and higher volumes in North America.<br>Costs of goods sold totaled R$15.4 billion in 1Q25, 4.2% higher than in 4Q24, also driven by higher shipment volume, as explained above.<br>Year-over-year, Costs of goods sold came 11.9% higher, mainly due to the Brazilian real devaluation against the U.S. dollar when<br>converting the foreign operations’ costs.<br>As a result, Gross profit totaled R$1.9 billion in 1Q25, 3.6% lower than in 4Q24 and 19.6% over 1Q24.<br>SELLING, GENERAL & ADMINISTRATIVE EXPENSES<br>Selling, General & Administrative (SG&A) expenses totaled R$543 million in 1Q25, down 7.4% from 4Q24, mainly reflecting lower<br>expenses in the Brazil and South America Segments. Year-over-year, SG&A came 8.4% higher, due to the effect of Brazilian real<br>devaluation against the U.S. dollar on the foreign operations results, which offset reductions reported by operations. As a percentage<br>of Net sales, SG&A expenses went down 0.4 p.p. from 4Q24 and came in line with 1Q24, reflecting net sales growth in the quarter.<br>CONSOLIDATED 1Q25 4Q24 ∆ 1Q24 ∆<br>Results (R$ million)<br>Net sales 17,375 16,822 3.3% 16,210 7.2%<br>Cost of goods sold (15,429) (14,802) 4.2% (13,791) 11.9%<br>Gross profit 1,947 2,020 -3.6% 2,420 -19.6%<br>Gross margin 11.2% 12.0% -0.8 p.p 14.9% -3.7 p.p<br>CONSOLIDATED 1Q25 4Q24 ∆ 1Q24 ∆<br>Results (R$ million)<br>SG&A (543) (586) -7.4% (501) 8.4%<br>Selling expenses (194) (199) -2.7% (183) 6.0%<br>General and admininstrative expenses (349) (387) -9.9% (318) 9.7%<br>%SG&A/Net Sales 3.1% 3.5% -0.4 p.p 3.1% -

Quarter-over-quarter, EBITDA came<br>in line due to: (i) improved results of North America Segment, driven by higher shipment volumes; (ii) lower costs of goods sold in South<br>America; and (iii) the SG&A decline across all Segments. These effects were offset by the weaker performance in Brazil due to price<br>pressure on some product lines, higher costs related to the scheduled shutdown for the implementation of the new hot-rolled coil mill,<br>as well as lower prices in South America. Year-over-year, Adjusted EBITDA went down 14.6%, influenced by the lower result in North<br>America, reflecting the reductions in steel prices over the course of 2024, partially offset by the higher shipment volume and the<br>exchange variation.<br>QUARTERLY CHANGE IN ADJUSTED EBITDA (R$ MILLION)<br>BREAKDOWN OF CONSOLIDATED EBITDA - (R$ million) 1Q25 4Q24 ∆ 1Q24 ∆<br>Net income 758 323 134.4% 2,053 -63.1%<br>Net financial result 308 628 -50.9% 476 -35.3%<br>Provision for income and social contribution taxes 320 43 649.0% 224 43.1%<br>Depreciation and amortization 874 833 4.9% 726 20.3%<br>EBITDA - CVM Instruction¹ 2,260 1,826 23.7% 3,479 -35.1%<br>Equity in earnings of unconsolidated companies (9) (79) -88.2% (79) -88.3%<br>Proportional EBITDA of associated companies and jointly controlled entities<br>(a) 147 202 -27.0% 202 -27.0%<br>Losses due to non-recoverability of financial assets 4 2 156.9% 20 -80.3%<br>Non-recurring items - 440 - (808) -<br>Credit recovery / Provisions (b) - 440 - - -<br>Result from operations with jointly controlled entities - - - (808) -<br>Adjusted EBITDA² 2,402 2,391 0.4% 2,813 -14.6%<br>Adjusted EBITDA margin 13.8% 14.2% -0.4 p.p 17.4% -3.5 p.p<br>CONCILIATION OF CONSOLIDATED EBITDA - (R$ million) 1Q25 4Q24 ∆ 1Q24 ∆<br>EBITDA - CVM Instruction ¹ 2,260 1,826 23.7% 3,479 -35.1%<br>Depreciation and amortization (874) (833) 4.9% (726) 20.3%<br>OPERATING INCOME BEFORE FINANCIAL RESULT AND TAXES 1,386 994 39.5% 2,752 -49.6%

Despite the lower volume of flat steel shipments in the domestic market, due to the<br>scheduled shutdown in Ouro Branco (MG) for the start-up of the hot coil expansion project, the long steel shipment volumes upturn<br>mitigated this effect. Year-over-year,the total shipments stability is explained by exports growth, offsetting the decline seen in the<br>domestic market, impacted mainly by the high imported steel penetration.<br>OPERATING RESULT<br>1- Includes iron ore sales.<br>2- Non-accounting measurement reconciled with information stated inNote 22 to the Company’s Financial Statements, as setforth by CVM Resolution 156, of June<br>23, 2022.<br> In 1Q25, net sales per tonne came 3.7% lower than in 4Q24, due to the tougher competitive environment in the domestic market,<br>considering the advance of imports and the entry of capacity from other players, causing downward pressure on prices in the long<br>steel segment, particularly in rebar. This effect was partially offset by better prices in other product lines. Year-over-year, net sales<br>per tonne grew 2.2%, fueled by improved price scenario in the domestic market and the Brazilian real devaluation, benefiting<br>exports profitability;<br> In 1Q25, the cost of goods sold per tonne came 2.7% higher than in 4Q24, mainly influenced by scheduled shutdown of Ouro Branco<br>industrial unit for expansion of the hot-rolled coil mill, as explained earlier. This increase was partially offset by a reduction of<br>approximately 10% in raw material costs, such as scrap and electricity. Year-over-year, the cost of goods sold per tonne came in<br>line, reinforcing the initiatives carried out in 2024 to cut costs and expenses, neutralizing increases due to inflation and exchange<br>rates;<br> The Adjusted EBITDA came 23.4% lower than in 4Q24 and 29.0% higher than in 1Q24, reflecting the operating results explained<br>above. In addition, in 1Q25, the Adjusted EBITDA partially benefited from lower SG&A, which fell by approximately 10% compared to<br>1Q24 and 4Q24, reflecting the Company's discipline in sustaining its expenses at healthy levels.<br>NORTH AMERICA<br>PRODUCTION & SHIPMENTS<br> In 1Q25, crude steel production and shipments came higher compared to 4Q24, driven by seasonal upturn and higher customer<br>inventory levels amid changes in the US trade policy.

Year-over-year, in Brazilian reais, Net sales was<br>influenced by the effect of U.S. dollar appreciation against the Brazilian real (+14.9%), which offset lower market prices;<br> In 1Q25, the cost of goods sold per tonne in U.S. dollars came 2.9% lower than in 4Q24 driven by greater dilution of fixed costs due<br>to higher shipments, partially offset by the scrap price increase over the quarter. Compared to 1Q24,the cost of goods sold pertonne<br>in U.S. dollars came 4.2% lower, mainly driven by efforts to control fixed costs and operational efficiency;<br> The recovery of Adjusted EBITDA and Adjusted EBITDA Margin from 4Q24, reflects the improved demand and prices, as mentioned<br>earlier.
