Note Regarding Non-GAAP Financial Measures

Certain information set forth in this press release, including non-GAAP income (loss), non-GAAP income (loss) per share, and adjusted EBITDA income (loss) are non-GAAP financial measures. Fulgent believes this information is useful to investors because it provides a basis for measuring the performance of the Company's business, excluding certain income or expense items that management believes are not directly attributable to the Company's operating results. Fulgent defines non-GAAP income (loss) as net income (loss) calculated in accordance with accounting principles generally accepted in the United States of America, or GAAP, plus amortization of intangible assets, plus restructuring costs, plus acquisition-related costs, including banking fees and legal fees associated with acquisitions, plus equity-based compensation expense, plus or minus the non-GAAP tax effect, and plus or minus other charges or gains, as identified, that management believes are not representative of the Company's operations. The non-GAAP tax effect is calculated by applying the statutory corporate tax rate on the amortization of intangible assets, restructuring costs, acquisition-related costs, and equity-based compensation expense. Fulgent defines adjusted EBITDA income (loss) as GAAP income (loss) plus or minus interest (expense) income, plus or minus provisions (benefits) for income taxes, plus restructuring costs, plus acquisition-related costs, plus equity-based compensation expense, plus depreciation and amortization, and plus or minus other charges or gains, as identified, that management believes are not representative of the Company's operations. Fulgent may continue to incur expenses similar to the items added to or subtracted from GAAP income (loss) to calculate non-GAAP income (loss) and adjusted EBITDA income (loss); accordingly, the exclusion of these items in the presentation of these non-GAAP financial measures should not be construed as an implication that these items are unusual, infrequent or non-recurring. Management uses these non-GAAP financial measures along with the most directly comparable GAAP

financial measure of net income (loss) in evaluating the Company's operating performance. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in conformity with GAAP, and non-GAAP financial measures as reported by Fulgent may not be comparable to similarly titled metrics reported by other companies.
