22 Summary Financials

Key Metrics 4.5 GW Solar cells shipped FY 2025 23 $427.4 M Revenues 249 MW Solar modules shipped $52.2M NON - GAAP Adjusted Net Income *First half 2025 figures are unaudited and unreviewed

Use of Non - GAAP Financial Measure Some of the financial information and data contained in this press release, such as EBITDA, Adjusted EBITDA and Adjusted Net Income have not been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). TOYO believes these non - GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to TOYO’s financial condition and results of operations. TOYO’s management uses these non - GAAP measures for trend analysis and for budgeting and planning purposes. TOYO believes that the use of these non - GAAP measures provides an additional tool for investors to evaluate projected operating results and trends, as well as compare TOYO’s financial measures with those of other similar companies, many of which also present similar non - GAAP financial measures to investors. Management of TOYO does not consider these non - GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non - GAAP financial measures is that they exclude significant expenses such as share - based compensation and changes in fair value of contingent consideration and income that are required by GAAP to be recorded in TOYO’s financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non - GAAP financial measures. You should review TOYO’s audited financial statements, which are presented in the most recent annual report on Form 20 - F filed with the SEC on March 31, 2026, and not rely on any single financial measure to evaluate TOYO’s business.
