Note Regarding Non-GAAP Financial Measures

Certain information set forth in this press release and/or to be discussed on the Company's earnings call, including non-GAAP income (loss), non-GAAP income (loss) per share, adjusted EBITDA income (loss), non-GAAP gross profit and margin, and non-GAAP operating income (loss) and margin 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 equity-based compensation expenses, 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. For the three and six months ended June 30, 2023, the non-GAAP tax effect was calculated by applying the statutory corporate tax rate on the amortization of intangible assets and equity-based compensation expenses. For the three and six months ended June 30, 2024, the non-GAAP tax effect was calculated by excluding from the GAAP provision the impact of the amortization of intangible assets and equity-based compensation expenses. 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 equity-based compensation expenses, 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 defines non-GAAP gross profit as gross profit calculated in accordance with GAAP plus equity-based compensation included in cost of revenue as shown in the table below. Fulgent defines non-GAAP gross margin by taking non-GAAP gross profit and dividing it by GAAP revenue. Fulgent defines non-GAAP operating profit (loss) by taking GAAP operating profit (loss) and adding equity-based compensation and amortization of intangible assets. Non-GAAP operating margin is calculated by taking non-GAAP operating profit (loss) and dividing by GAAP revenue. 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), gross profit and margin, and operating income (loss) and margin, 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.

Fulgent is a technology-based company with a well-established laboratory services business and a therapeutic development business. Fulgent's laboratory services business, which was formerly referred to as the clinical diagnostic business, includes technical laboratory services and professional interpretation of laboratory results by licensed physicians. Fulgent's therapeutic development business is focused on developing drug candidates for treating a broad range of cancers using a novel nanoencapsulation and targeted therapy platform designed to improve the therapeutic window and pharmacokinetic profile of new and existing cancer drugs. The Company aims to transform from a genomic diagnostic business into a fully integrated precision medicine company.
