Fulgent Genetics Reports First Quarter 2020 Financial Results

First Quarter 2020 Results:

TEMPLE CITY, CA, May 4, 2020 —Fulgent Genetics (NASDAQ: FLGT) (“Fulgent Genetics” or the “company”), a provider of comprehensive genetic testing and Next Generation Sequencing (“NGS”) solutions, today announced financial results for its first quarter of fiscal year 2020 ended March 31, 2020.

First quarter revenue was $7.8 million, an increase of 44% year over year from $5.4 million in the first quarter of 2019. GAAP loss for the first quarter of 2020 was $2.0 million, or $0.09 per share, and non-GAAP loss was $749,000, or $0.03 per share.

Adjusted EBITDA loss was $506,000 in the first quarter of 2020, compared to $712,000 in the first quarter of 2019.

Non-GAAP income (loss) and adjusted EBITDA are described below under “Note Regarding Non-GAAP Financial Measures” and are reconciled to the most directly comparable GAAP financial measure, GAAP income (loss), in the accompanying tables.

Ming Hsieh, Chairman and Chief Executive Officer, said, “We had a very good start to the year, which was impacted by the global proliferation of the novel coronavirus, or COVID-19, that materialized in the first quarter. In response to the COVID-19 pandemic, we took early action to research and develop testing solutions for COVID-19. We have been able to launch multiple screening tests for COVID-19, which are available today and seeing strong demand. While volume from our core rare disease, oncology and reproductive health businesses has been challenged in this unprecedented macro environment, we were pleased to deliver strong year over year growth in both revenue and billable test volume in the first quarter. Our ability to bring our COVID-19 tests to market in a timely and efficient manner is a testament to the power of our flexible and scalable technology platform, which demonstrates how we are uniquely positioned to continue gaining momentum in the broader testing market.”

Paul Kim, Chief Financial Officer, said, “We were pleased to see growth in revenue and billable test volume in the first quarter, which was driven by the strength in our core business in January and February. Coinciding with timing of our launch for COVID-19 offerings, we began seeing demand for our COVID-19 tests in the final week of the quarter. We also made significant investments across our business during the quarter, that are directly attributable to the research, development and launch efforts for our COVID-19 tests. These investments impacted our average selling price, average cost per

test and operating expenses in the quarter, and are reflected in our bottom line. Despite these dynamics, we generated approximately $1.4 million in cash flow from operations in the quarter. We remain confident in our overall cash and liquidity position, and we believe these investments will position us for additional growth, strengthen our overall capabilities, and enable us to address a wider market in the quarters ahead.”

Mr. Kim added, “We will provide a formal update on our guidance regarding certain financial measures during our investment community conference call to shortly follow the issuance of this press release.”

Note Regarding Non-GAAP Financial Measures

Certain of the information set forth in this press release, including non-GAAP income (loss) and adjusted EBITDA, are non-GAAP financial measures. Fulgent Genetics 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 core operating results. Fulgent Genetics defines non-GAAP income (loss) as income (loss) calculated in accordance with accounting principles generally accepted in the United States of America (“GAAP”), plus or minus provisions (benefits) for income taxes, plus equity-based compensation expenses, plus or minus equity income (loss) in investee, plus or minus the effect of a corporate tax rate, and plus or minus other charges or gains, as identified, that management believes are not representative of the company’s core operations. Fulgent Genetics defines adjusted EBITDA as GAAP income (loss) plus or minus interest expense (income), plus or minus provisions (benefits) for income taxes, plus depreciation, plus equity-based compensation expenses, plus or minus equity income (loss) in investee, and plus or minus other charges or gains, as identified, that management believes are not representative of the company’s core operations.

Fulgent Genetics 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; 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 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 Genetics may not be comparable to similarly titled metrics reported by other companies.
