MIAMI (February 24, 2022) – OPKO Health, Inc. (NASDAQ: OPK) reports business highlights and financial results for the three months ended December 31, 2021.

•NGENLA® (somatrogon) injection granted regulatory approvals in Europe, Japan, Australia and Canada for pediatric growth hormone deficiency. NGENLA® is a once-weekly, long-acting recombinant human growth hormone for the long-term treatment of growth hormone deficiency (GHD) in pediatric patients. NGENLA® has been approved in the European Union, including Iceland, Norway and Liechtenstein, Japan, Australia and Canada. Under the worldwide agreement with Pfizer Inc., OPKO is eligible to receive a milestone payment after regulatory approvals and pricing determinations are obtained in major markets outside of the U.S. NGENLA® became commercially available in Canada to patients with pediatric growth hormone deficiency on February 16, 2022, the product’s first commercial launch.

•RAYALDEE® launched in Germany by OPKO’s licensee, Vifor Fresenius Medical Care Renal Pharma (VFMCRP). VFMCRP has initiated the commercial launch of RAYALDEE (extended-release calcifediol) in Germany, the first launch of RAYALDEE outside the U.S. VFMCRP is OPKO’s commercial partner for RAYALDEE in Europe and selected markets outside the U.S. The sales kick-off in Germany began with presentations from several nephrology key opinion leaders. VFMCRP has received marketing authorizations for RAYALDEE in 11 European countries and expects to launch the product in additional markets.

•Topline results reported from a Phase 2 clinical trial evaluating RAYALDEE as a treatment for symptomatic COVID-19 outpatients. Topline data indicate that improving vitamin D status with oral RAYALDEE results in earlier resolution of respiratory symptoms associated with mild-to-moderate COVID-19. A preprint manuscript summarizing the topline results is available on medRxiv. This manuscript is currently under review for publication in a peer-reviewed medical journal. We plan to discuss potential next steps with the FDA.

•Definitive agreement signed for Sema4 Holdings Corp. (Sema4) to acquire GeneDx, Inc., a leader in genomic testing and analysis. Upon completion of the transaction, OPKO anticipates Sema4 and GeneDx will be one of the largest and most advanced providers of genomic clinical testing in the U.S., with a projected $350 million in pro forma 2022 revenue. Under the terms of the agreement, Sema4 will acquire GeneDx for an upfront payment of $150 million in cash plus 80 million shares of Sema4 common stock, with up to an additional $150 million in revenue-based milestones over the next two years (payable in cash or Sema4 shares at Sema4’s discretion).  Based on the closing price of Sema4’s common stock on January 14, 2022, the total upfront consideration is approximately $473 million and the total aggregate consideration including potential milestones is approximately $623 million. As part of the transaction, Sema4

•BioReference Laboratories (BRL) processed approximately 2.7 million COVID-19 PCR tests in the fourth quarter of 2021 versus 2.2 million in the third quarter of 2021. Demand for COVID-19 PCR tests increased significantly due to the Omicron variant beginning late in the fourth quarter of 2021 and continuing into the first quarter of 2022.

•FDA approved the Premarket Approval Application (PMA) of the 4Kscore® Test. This test is approved for use in men aged 45 years and older who have not had a prior prostate biopsy or are biopsy negative and have an age-specific abnormal total prostate specific antigen (PSA) and/or abnormal digital rectal exam. The 4Kscore Test in the intended use population, when used in conjunction with other clinical factors and patient preferences, can contribute to a properly informed decision as to whether or not to proceed with a prostate biopsy. The regulatory approval provides further validation of the 4Kscore Test as an important diagnostic tool and should assist in expanding reimbursement coverage.  

•Consolidated: Consolidated total revenues for the fourth quarter of 2021 were $401.3 million compared with $494.6 million for the comparable period of 2020. Operating loss for the fourth quarter of 2021 was $63.1 million compared with operating income of $49.3 million for the comparable period of 2020. Net loss for the fourth quarter of 2021 was $73.8 million, or $0.11 per share, compared with net income of $32.3 million, or $0.05 per diluted share, for the comparable period of 2020. Operating loss for the fourth quarter of 2021 included non-recurring legal expenses, as well as expenses related to the GeneDx transaction.

•Diagnostics: Revenue from services in the fourth quarter of 2021 were to $362.8 million compared to $457.9 million in the prior-year period, primarily due to a decrease in COVID-19 testing volume. Total costs and expenses were $381.4 million in the fourth quarter of 2021 compared to $388.0 million in the fourth quarter of 2020, resulting in an operating loss of $18.6 million compared to operating income of $69.9 million in the 2020 period. The lower operating income is primarily due to a decline in COVID-19 test volume and increased investment in BRL’s base business and digital health activities, principally related to Scarlet. Included in the fourth quarter 2021 results were revenue of $33.1 million and costs and expenses of $43.4 million at GeneDx compared with revenue of $20.3 million and costs and expenses of $36.6 million for the fourth quarter of 2020.

•Pharmaceuticals: Revenue from products in the fourth quarter of 2021 increased nearly 15% to $35.3 million compared to $30.8 million in the fourth quarter of 2020, with the increase primarily attributable to the accelerating growth of OPKO’s international pharmaceutical businesses. Revenue from sales of RAYALDEE in the fourth quarter of 2021 was $7.7 million compared to $10.1 million in the prior-year period. Sales of RAYALDEE were negatively impacted by challenges in onboarding new patients due to the COVID-19 pandemic. Revenue from the transfer of intellectual property was $3.3 million in the fourth quarter of 2021 compared to $5.9 million in the 2020 period. Total costs and expenses were $53.3 million in the fourth quarter of 2021 compared to $45.7 million in the prior-year period, reflecting an increase in the cost of product revenue at OPKO’s international operating companies related to higher sales and ongoing expenses for the somatrogon program to support open-label extension

•Cash and equivalents: Cash, cash equivalents and marketable securities were $134.7 million as of December 31, 2021. In addition, the Company has $64.8 million available under its line of credit with JP Morgan.
