•Health Canada approved NGENLA™ (somatrogon) injection for pediatric growth hormone deficiency. NGENLA is a once-weekly, long-acting recombinant human growth hormone, for the long-term treatment of pediatric patients who have growth failure due to an inadequate secretion of endogenous growth hormone (growth hormone deficiency, or GHD).

Global regulatory applications for somatrogon continue to advance with action dates in the U.S., Europe and Japan expected during the first half of 2022.

•BioReference Laboratories (BRL) processed approximately 2.2 million COVID-19 PCR tests in the third quarter of 2021. In addition, during the quarter BRL performed approximately 158,100 COVID-19 serology tests to measure SARS-CoV-2 antibody levels and currently has significant additional capacity. In August 2021 Rite Aid, the U.S. Department of Health and Human Services, and BRL announced a “Back to School” COVID-19 testing program offering students at New York State public schools the opportunity for free COVID-19 testing prior to or at the start of the 2021-2022 school year. Students will be tested using highly accurate RT-PCR laboratory-based COVID-19 tests.

•BRL acquired the U.S. Ariosa centralized laboratory prenatal testing business from Roche. Ariosa's noninvasive prenatal screening (NIPS) test, the Harmony Prenatal Test, is one of the most widely studied tests utilized in prenatal screening. This test has been performed in more than 1.5 million patients. The acquisition of Ariosa will complement the current NIPS offering at GenPath, BRL’s specialty health division.

•Completed enrollment in Phase 2 trial evaluating RAYALDEE® as a treatment for symptomatic COVID-19 outpatients. The U.S. trial, “A Randomized, Double-Blind Placebo-Controlled Study to Evaluate the Safety and Efficacy of RAYALDEE (calcifediol) Extended-release Capsules to Treat Symptomatic Patients Infected with SARS-CoV-2,” completed final enrollment with 171 subjects, including some with stage 3 or 4 chronic kidney disease who are at higher risk for developing more severe illness. Topline data are expected later this year.

•Formed a joint venture with LeaderMed Group to develop, manufacture and commercialize oxyntomodulin and Factor VIIa-CTP in China and other Asian territories. Under the terms of the agreements, OPKO granted the joint venture exclusive rights to develop, manufacture and

•Executed exclusive worldwide agreement with CAMP4 Therapeutics Corporation (CAMP4) for the development, manufacture and commercialization of therapeutics utilizing the AntagoNAT technology. This technology is an oligonucleotide platform developed under OPKO CURNA. CAMP4 has prioritized OPKO’s lead AntagoNAT compound to progress into clinical trials for the treatment of Dravet syndrome. Under the terms of the agreement, OPKO received an upfront payment and shares of privately held CAMP4. In addition, OPKO will be eligible to receive up to $93.5 million and additional shares upon the achievement of certain development and sales milestones for products developed from this technology and associated intellectual property. CAMP4 will also pay OPKO double-digit royalties on product sales.

•Consolidated: Consolidated total revenues for the third quarter of 2021 were $385.8 million compared with $428.1 million for the comparable period of 2020. Operating income for the third quarter of 2021 increased 72% to $37.8 million compared with $21.9 million, for the comparable period of 2020. Net income for the third quarter of 2021 was $28.7 million, or $0.04 per diluted share, compared with $23.7 million, or $0.04 per diluted share, for the comparable period of 2020.

•Diagnostics: Revenue from services in the third quarter of 2021 decreased to $340.1 million from $382.5 million in the prior-year period, primarily due to a decrease in COVID-19 testing volume, which was partially offset by an improvement in COVID-19 test reimbursement and an increase in clinical and genomic test revenue. Total costs and expenses were $320.5 million in the third quarter of 2021 compared with $346.4 million in the third quarter of 2020, resulting in operating income of $19.7 million compared with $46.2 million in the 2020 period. The decrease in operating income is primarily due to a decline in COVID-19 test volume and an increased level of investment in our commercial organization for our base business and digital health activities resulting in increased professional fees and personnel expenses. During the third quarter of 2020, BioReference received a $10.0 million non-recurring grant under the CARES Act.

•Pharmaceuticals: Revenue from products in the third quarter of 2021 increased almost 29% to $36.9 million compared with $28.7 million in the third quarter of 2020, with the increase primarily attributable to accelerating growth within OPKO’s international pharmaceutical businesses. Total prescriptions for RAYALDEE in the third quarter of 2021 decreased to approximately 11,500 from approximately 16,700 in the third quarter of 2020. Revenue from sales of RAYALDEE in the third quarter of 2021 was $8.5 million compared with $8.1 million in the prior-year period, with the increase reflecting a higher net realized price as a result of lower Medicare Part D rebates. Revenue from the transfer of intellectual property was $8.8 million in the third quarter of 2021 compared with $6.8 million for the 2020 period. The increase reflects the CAMP4 and LeaderMed agreements partially offset by a decrease in revenue related to the Pfizer transaction. Total costs and expenses were $17.0 million in the third quarter of 2021 compared with $49.9 million in the prior-year period, primarily due to a $31.5 million gain on the sale of assets to Horizon Therapeutics plc for OPKO’s sterile-fill-finish manufacturing facility

•Cash and equivalents: Cash, cash equivalents and marketable securities were $148.6 million as of September 30, 2021. In addition, the Company has $64.3 million availability under its line of credit with JP Morgan.
