We are a diversified healthcare company that seeks to establish industry-leading positions in large and rapidly growing medical markets. Our diagnostics business includes BioReference Laboratories, Inc. (“BioReference”), one of the nation’s largest full service laboratories with an almost 250-person sales and marketing team to drive growth and leverage new products. Our pharmaceutical business features Rayaldee, a U.S. Food and Drug Administration (“FDA”) approved treatment for secondary hyperparathyroidism (“SHPT”) in adults with stage 3 or 4 chronic kidney disease (“CKD”) and vitamin D insufficiency, and a pipeline of products in various stages of development. Our leading product in development is Somatrogon (hGH-CTP), a once-weekly human growth hormone injection for which we completed a successful phase 3 study in August 2019 and is partnered with Pfizer Inc. (“Pfizer”). Regulatory applications for Somatrogon have been submitted to several countries around the world for review. In February 2022, the European Commission granted marketing authorization in the European Union for Somatrogon under the brand name NGENLA® to treat children and adolescents from as young as 3 years of age with growth disturbance due to insufficient secretion of growth hormone. In January 2022, the Ministry of Health, Labour and Welfare in Japan approved NGENLA® (Somatrogon) for the long-term treatment of pediatric patients who have growth failure due to an inadequate secretion of endogenous growth hormone. In October 2021, Health Canada approved NGENLA® for the long-term treatment of pediatric patients who have growth hormone deficiency, and in November 2021, Australia’s Therapeutic Goods Administration approved NGENLA® for the long-term treatment of pediatric patients with growth disturbance due to insufficient secretion of growth hormone. We also submitted the initial Biologics License Application (“BLA”) with the FDA for approval of Somatrogon in the United States and Pfizer received a complete response letter in January 2022. Pfizer and OPKO are evaluating the FDA’s comments and will work with the agency to determine an appropriate path forward for the advancement of hGH (Somatrogon).

Through BioReference, we provide laboratory testing services, primarily to customers in the larger metropolitan areas in New York, New Jersey, Florida, Texas, Maryland, California, Pennsylvania, Delaware, Washington, DC, Illinois and Massachusetts, as well as to customers in a number of other states. We offer a comprehensive test menu of clinical diagnostics for blood, urine and tissue analysis. This includes hematology, clinical chemistry, immunoassay, infectious disease, serology, hormones, and toxicology assays, as well as Pap smear, anatomic pathology (biopsies) and other types of tissue analysis, as well as testing for COVID-19. We market our laboratory testing services directly to physicians, geneticists, hospitals, clinics, correctional and other health facilities.

We launched our first pharmaceutical product, Rayaldee, in the U.S. market in the fourth quarter of 2016. We have under development a broad and diversified portfolio of diagnostic tests, small molecules, and biologics targeting a broad range of unmet medical needs. We also operate one of the largest full service laboratories in the U.S. We intend to continue to leverage

•continue to enhance our commercialization capability in the U.S. and internationally;

•develop and commercialize Rayaldee for new indications, including the treatment of SHPT in patients with vitamin D insufficiency and stage 5 CKD requiring regular hemodialysis;

•obtain requisite regulatory approval and compile clinical data for our most advanced product candidates; and

•expand into other medical markets that provide significant opportunities and that we believe are complementary to and synergistic with our business.

In addition, we expect to leverage the BioReference business and infrastructure to drive rapid and widespread uptake of our diagnostic products. Our strategy with respect to BioReference Laboratories is comprised of three pillars: the core business, digital health and strategic ventures. Because of the COVID-19 outbreak, we have added a fourth pillar as the COVID-19 pandemic impacted all parts of our organization. In support of this strategy:

•We have made significant investments to rebuild and reconfigure our main laboratory in Elmwood Park, NJ and have also made significant investments in our labs in Melbourne, Florida, Houston, Texas, California and the GeneDx laboratory in Maryland.

•We have facilitated increased patient access through preferred relationships with payors. We are part of the United Healthcare preferred lab network with access to approximately 45 million patients. We now also have access to Blue Cross/Blue Shield of Texas with another approximately 5.9 million patients and access to Blue Cross/Blue Shield of Alabama with another approximately 2 million patients.

•We intend to continue to expand large-scale COVID-19 screening programs nationwide. We offer customized solutions to different types of environments and to different types of clients. We are one of the largest providers of these programs, which include both PCR COVID-19 testing and point of care testing, across a variety of touch points, including the travel and leisure industry, airlines, cruise industry and education. BioReference has provided COVID-19 testing to the NFL, NBA, NHL, US National Soccer Teams, Winter X Games and the US Golf Association, among other organizations.

•We intend to continue to expand our offerings among our core laboratory service businesses in clinical, genetics, women’s health, oncology and urology.

•We intend to initiate digital health advances that aim to increase flexibility and convenience for patients. We recently introduced an important initiative in digital health through the launch of Scarlet™ Health, a fully-integrated digital platform providing mobile phlebotomy and laboratory services to patient’s homes, offices and other preferred locations.

•We intend to continue to expand and seek new strategic ventures to provide laboratory services for large health care groups and systems.

•BioReference Laboratories. BioReference constitutes our core clinical testing laboratory offering automated, high volume routine testing services, COVID-19 testing, STAT testing, informatics, HIV, Hep C and other molecular tests.

•GenPath (Oncology). National oncology presence with expertise in cancer pathology and diagnostics, as well as molecular diagnostics. Core tests include FLOW, IHC, MicroArray, FISH, ISH, Morphology, and full service oncology.

•GenPath (Women’s Health). Innovative technology platform for sexually transmitted infections has enabled expansion nationally with specimens coming from 41 states, including Image Directed Paps analysis, HPV Plus, and STI Testing.

•GeneDx. Industry leading national laboratory for testing rare and ultra-rare genetic diseases with international reach, performing testing on specimens from more than 50 countries. We recently entered into an Agreement and Plan of Merger and Reorganization (the “GeneDx Merger Agreement”) with Sema4 Holdings Corp., a Delaware corporation (“Sema4”), pursuant to which Sema4 has agreed to acquire our wholly-owned subsidiary, GeneDx, Inc. (“GeneDx”), subject to the satisfaction of customary closing conditions.

We are among the largest providers of large-scale COVID-19 screening programs across the country, with the capacity to run approximately 100,000 PCR tests a day. These large-scale screening programs include both PCR COVID-19 testing and point of care testing. We offer testing across a variety of touch points, including the travel and leisure industry, airlines, cruise industry and education. We have substantial relationships with local and state governments to provide testing services across all 50 states, with substantial service relationships in New York, New Jersey, and Michigan. Through our relationships with CVS and RiteAid, we provide access to testing services for the general public and currently provide testing at more than 700 CVS and RiteAid storefronts. BioReference has provided COVID-19 testing for the NFL, NBA, NHL, U.S. National Soccer Teams, Winter X Games and the US Golf Association, among other organizations.

BioReference provides us with a significant diagnostics commercial infrastructure for marketing and sales that reached approximately 21 million and 19 million patients, respectively, in 2021 and 2020. In addition, its large team of managed care experts complement our efforts to ensure that payors recognize the value of our diagnostic and laboratory tests for reimbursement purposes. We continue to leverage the national marketing, sales and distribution resources of BioReference, along with its almost 250-person sales and marketing team, to enhance sales of and reimbursement for our 4Kscore test, a laboratory developed blood test that provides a personalized risk score for aggressive prostate cancer. We plan to leverage the BioReference commercial infrastructure and capabilities, as well as its extensive relationships with payors, to commercialize OPKO’s other diagnostic products under development.

We offer the 4Kscore test through BioReference. We began selling the 4Kscore test in the U.S. in March 2014 and in Europe and Mexico in September 2014 and January 2015, respectively. The 4Kscore test was approved by the FDA in December 2021 for use in men age 45 and older who have not had a prior prostate biopsy or a biopsy negative and have an age specific abnormal total PSA or abnormal digital rectal exam (DRE). The 4Kscore test is a laboratory developed test that measures the blood serum or plasma levels of four different prostate-derived kallikrein proteins: Total PSA, Free PSA, Intact PSA and Human Kallikrein-2 (“hK2”). These biomarkers are then combined with a patient’s age, optional DRE status (nodule / no nodule), and prior negative biopsy status (yes, prior negative biopsy / no prior biopsy) using a proprietary algorithm to calculate the risk (probability) of finding a Gleason Score 7 or higher prostate cancer. The four kallikrein panel of biomarkers utilized in the 4Kscore test is based on decades of research conducted by scientists at Memorial Sloan-Kettering Cancer Center and leading European institutions. Investigators at the Lund University, Sweden, University of Turku, Finland and Memorial Sloan Kettering Cancer Center, New York, have also demonstrated that the 4Kscore test can risk stratify the 20-year risk for development of prostate metastases and mortality in men who present at age 50 to 60 years old with an elevated PSA.

The 4Kscore test was developed by OPKO and validated in two prospective, blinded studies of 1,012 and 366 men, respectively. The first study was done in collaboration with 26 urology centers across the U.S. and the second study was conducted at eight VA centers in the U.S. with a predominantly African American cohort. African Americans are 1.7 times more likely to be diagnosed with prostate cancer than Caucasian men and 2.2 times more likely to die from the disease. Results showed that the 4Kscore test was highly accurate for predicting the presence of high-grade cancer (Gleason Score 7 or higher) prior to prostate biopsy, regardless of race. The full data from the blinded, prospective U.S. clinical validation studies have been published in peer reviewed medical journals.

The clinical data from both studies demonstrated the ability of the 4Kscore test to discriminate between men with high-grade, aggressive prostate cancer and those men who had no findings of cancer or had low-grade or indolent form of the disease. In separate clinical studies, use of the 4Kscore test led to 64.6% fewer biopsies and was able to discriminate between men with high-grade aggressive prostate cancer and those with no findings of cancer.

The National Comprehensive Cancer Network (“NCCN”) has included the 4Kscore test as a recommended test in its Guidelines for Prostate Cancer Early Detection since 2015. The panel making this recommendation concluded that the 4Kscore test is indicated for use prior to a first prostate biopsy, or after a negative biopsy, to assist patients and physicians in further defining the probability of high-grade cancer. In addition, the European Association of Urology (“EAU”) Prostate Cancer Guidelines Panel included the 4Kscore test in their Guidelines for Prostate Cancer since 2018, concluding that the 4Kscore, as a blood test with greater specificity over the PSA test, is indicated for use prior to a first prostate biopsy or after a negative biopsy to assist patients and physicians in further defining the probability of high-grade cancer.

The 4Kscore test has been granted a Category I CPT® code by the AMA (CPT Code 81539). A CPT code is used by insurance companies and government payors to describe health care services and procedures. A Category I CPT code is critical to facilitate reimbursement in government programs such as Medicare and Medicaid, as well as private insurance programs. Effective December 30, 2019, Novitas Solutions (“Novitas”), the local Medicare Administrative Contractor (“MAC”) for the 4Kscore testing laboratory in New Jersey, provided positive coverage through a local coverage determination (an “LCD”) with defined coverage criteria. Since that date, 4Kscore test orders meeting the coverage criteria have been reimbursed by Novitas and Medicare Advantage Health Plans.

Rayaldee is a patented extended release product containing 30 mcg of a prohormone, called calcifediol (25-hydroxyvitamin D3), for oral administration. We launched Rayaldee, our lead renal product, in the U.S. market in November 2016, following receipt in June 2016 of FDA approval for the treatment of SHPT in adults with stage 3 or 4 CKD and vitamin D insufficiency, defined as serum total 25-hydroxyvitamin D levels less than 30 ng/mL. The FDA approval of Rayaldee was supported by successful results from two identical randomized, double-blind, placebo-controlled, multi-site phase 3 studies which established the safety and efficacy of Rayaldee as a new treatment for SHPT in adults with stage 3 or 4 CKD and vitamin D insufficiency.

We have a 57-person highly specialized sales, marketing and market access team dedicated to the commercialization of Rayaldee as of December 31, 2021. In the fourth quarter of 2021, total Rayaldee prescriptions decreased approximately 28.8% and 1.4% as compared to the fourth quarter of 2020 and the third quarter of 2021, respectively. Sales of Rayaldee have not increased in accordance with its expected growth trajectory as a result of challenges in onboarding new patients due to the COVID-19 pandemic. Efforts are underway to obtain broader commercial and Part D insurance coverage for Rayaldee. We have already achieved commercial and Medicare Part D formulary coverage for more than 79.9% of U.S. covered lives as of the end of 2021.

In May 2016, we entered into a development and license agreement (the “VFMCRP Agreement”) with Vifor Fresenius Medical Care Renal Pharma (“VFMCRP”) for the development and commercialization of Rayaldee in Europe, Canada, Mexico, Australia, South Korea and certain other international markets for the treatment of SHPT in patients with stage 3, 4 or 5 CKD and vitamin D insufficiency. The VFMCRP Agreement was later amended to exclude South Korea, the Middle East and all of the countries of Africa from the VFMCRP Territory (as defined in the VFMCRP Agreement), and further amended to include Japan as part of the VFMCRP Territory.

VFMCRP initiated the commercial launch of Rayaldee in Germany in February 2022 and has received marketing authorization from eleven European countries to date and is preparing for product launches in additional territories in 2022. The launch in Germany triggered a $3 million payment to EirGen Pharma Ltd. (“EirGen”), our wholly owned subsidiary.

On June 18, 2021, EirGen and NICOYA Macau Limited (“Nicoya”), a Macau corporation and an affiliate of NICOYA Therapeutics, entered into a Development and License Agreement (the “Nicoya Agreement”) granting Nicoya the exclusive rights for the development and commercialization of extended release calcifediol (the “Nicoya Product”) in Greater China, which includes mainland China, Hong Kong, Macau, and Taiwan (collectively, the “Nicoya Territory”). Extended release calcifediol is marketed in the U.S. by OPKO under the tradename Rayaldee. The license grant to Nicoya covers the therapeutic and preventative use of the Nicoya Product for SHPT in non-dialysis and hemodialysis chronic kidney disease patients (the “Nicoya Field”).

OPKO and VFMCRP collaborated to complete a phase 2 study evaluating a higher strength dosage form of Rayaldee for the treatment of SHPT in hemodialysis patients. The study commenced in the 3rd quarter of 2018 and topline data were presented in an abstract titled “Initial Evaluation of High-Dose Extended-Release Calcifediol (ERC) in Patients with Stage 5 Chronic Kidney Disease on Hemodialysis” at the American Society of Nephrology’s Kidney Week Annual Meeting in November 2021.

In October 2020, we commenced a placebo controlled Phase 2 trial with Rayaldee as a treatment for mild-to-moderate COVID-19. In August 2021, the trial completed enrollment of 171 symptomatic patients from multiple U.S. sites and randomized in a 1:1 ratio for 4 weeks of treatment with Rayaldee or placebo and a 2-week follow-up. The trial ended in November 2021 and topline data were reported in December 2021 which indicated that improving vitamin D status with oral Rayaldee results in earlier resolution of respiratory symptoms associated with COVID-19. Data from the trial and potential next steps in the development program for this indication will be reviewed with the FDA later this year.

We have also completed a Phase 4 clinical trial comparing Rayaldee with three common treatment regimens for SHPT in adults with stage 3 or stage 4 CKD and vitamin D insufficiency. Preliminary results indicate that a daily dose of 60 micrograms of Rayaldee is the only one of four treatment regimens that reliably raises serum total 25-hydroxyvitamin D to the range of 50-100 mg/ml level required to effectively suppress elevated plasma parathyroid hormone levels in CKD patients. We presented interim results in an abstract titled “Comparison of Extended-Release Calcifediol (ERC), Immediate-Release Calcifediol, Cholecalciferol, and Paricalcitol for Treating Secondary Hyperparathyroidism (SHPT) in CKD” at the American Society of Nephrology’s Kidney Week Annual Meeting in October 2020.

We believe the CKD patient population is large and growing as a result of obesity, hypertension and diabetes; therefore this patient population represents a significant global market opportunity. According to the U.S. Renal Data System, CKD afflicts over 37 million people in the U.S., including more than 18 million patients with stage 3 or 4 CKD. In stage 5 CKD, kidney function is minimal to absent and most patients require regular dialysis or a kidney transplant for survival. An estimated 71-97% of CKD patients have vitamin D insufficiency which can lead to SHPT and its debilitating consequences. CKD continues to be associated with poor outcomes, reflecting the inadequacies of the current standard of care. We intend to develop and commercialize Rayaldee to constitute part of the foundation for a new and markedly improved standard of care for CKD patients having SHPT and/or hyperphosphatemia.

In addition to the phase 3 pediatric study, we have continued without interruption our ongoing phase 2 pediatric open label extension study for hGH-CTP. Most of the phase 2 pediatric patients have been treated with hGH-CTP for more than six years, and some patients for more than seven years. We have switched all of the pediatric patients in this study to the disposable pen device. A 44-patient Phase 3 study in Pediatric GHD patients in Japan was completed in the first quarter of 2020. The Japan Phase 3 clinical trial met its primary and secondary objectives, and demonstrated that the efficacy and safety of hGH-CTP administered weekly was comparable to Genotropin® as measured by annual height velocity after 12 months of treatment in pre-pubertal children with GHD. The findings were consistent with the results previously reported in the Phase 3 global study. The least squared means for the annual height velocity was higher in the Somatrogon group (9.65 cm/year) than in the Genotropin group (7.87 cm/year).

We submitted the initial Biologics License Application (“BLA”) with the FDA for approval of Somatrogon in the United States and Pfizer recently received a Complete Response Letter. Pfizer and OPKO are evaluating the FDA’s comments and will work with the agency to determine an appropriate path forward. Regulatory applications for Somatrogon have been submitted to several countries around the world for review. In February 2022, the European Commission granted marketing authorization in the European Union for Somatrogon under the brand name NGENLA® to treat children and adolescents from as young as 3 years of age with growth disturbance due to insufficient secretion of growth hormone. In January 2022, the Ministry of Health, Labour and Welfare in Japan approved NGENLA® (Somatrogon) for the long-term treatment of pediatric patients who have growth failure due to an inadequate secretion of endogenous growth hormone. In October 2021, Health Canada approved NGENLA® for the long-term treatment of pediatric patients who have growth hormone deficiency, and in November 2021, Australia’s Therapeutic Goods Administration approved NGENLA® for the long-term treatment of pediatric patients with growth disturbance due to insufficient secretion of growth hormone.

•The active group had a mean change in trunk fat mass of -0.4kg and placebo group was 0;

•There was no statistically significant difference (≤ 0.05 (p value)) between the active and placebo group;

•97% of hGH-CTP vs 6% of placebo group showed IGF-1 normalization; and

•The safety profile of hGH-CTP is consistent with that observed with those treated with daily growth hormone.

Although there was no statistically significant difference between hGH-CTP and placebo on the primary endpoint of change in trunk fat mass from baseline to 26 weeks, after unblinding the study, we identified an exceptional value of trunk fat mass reduction in the placebo group that may have affected the primary outcome. We have completed post-hoc sensitivity analyses to evaluate the influence of outliers on the primary endpoint results using multiple statistical approaches. Analyses that excluded outliers showed a statistically significant difference between hGH-CTP and placebo on the change in trunk fat mass. Additional analyses that did not exclude outliers showed mixed results. Further, significant changes were observed with hGH-CTP treatment in secondary endpoints such as lean body mass and compared to placebo. We believe there is a path for submission of a BLA with respect to hGH-CTP for adults with GHD on the basis that the FDA may assess the totality of the data, including all relevant efficacy and safety data in adult and pediatric patients. We plan to continue to assess with Pfizer the regulatory strategy for the adult indication going forward, including the timing of a possible submission.

During the years ended December 31, 2021, 2020, and 2019, we incurred $76.9 million, $75.3 million, and $117.9 million, respectively, of research and development expenses related to our various product candidates. During the years ended December 31, 2021, 2020, and 2019, our research and development expenses primarily consisted of hGH-CTP and Rayaldee development programs.

We have multiple U.S. patent families relating to Rayaldee. These patents are also filed in multiple countries worldwide. One patent family claims a sustained release oral dosage formulation and a method of treating 25-hydroxyvitamin D insufficiency or deficiency and will not expire until at least February 2027. A second patent family claims a method of administering 25-hydroxyvitamin D3 by controlled release, a formulation for controlled release of a vitamin D compound, a controlled release oral dosage formulation of a vitamin D compound and a method of treatment, and will not expire until at least April 2028. We also have additional patents and patent applications pending relating to the sustained release formulation and its use which will expire in 2034. The patents issued in the U.S. covering Rayaldee are listed in the Approved Drug Products with Therapeutic Equivalence Evaluations, or the Orange Book. OPKO and/or its affiliates have entered into exclusive license agreements with respect to Rayaldee patents in certain territories outside of North America with VFMCRP (Europe and many other countries throughout the rest of the world), and Nicoya Macau Limited (China). We intend to seek patent term extensions in those countries for which such protection is potentially available. We also continue to file and seek patent protection on various uses of extended release dosage forms of 25-hydroxyvitamin D3 and new formulations of this drug. EirGen’s patent publication US2021/0308151 disclosing and claiming the use of 25-hydroxyvitamin D3 and controlled release formulations thereof to treat SARS-CoV-2 infection was published on October 7, 2021.

Somatrogon (hGH-CTP)

Our strategy is to develop a portfolio of product candidates through a combination of internal development, acquisition, and external partnerships. Collaborations are key to our strategy and we continue to build relationships and forge partnerships in various areas where unmet medical need and commercial opportunities exist. In October 2017, we entered into a license and development agreement with JT for the development and commercialization of Rayaldee in Japan for the treatment of SHPT in non-dialysis and dialysis patients with CKD. Immediately following JT’s termination of this Agreement in May 2021, VFMCRP entered into an agreement with OPKO pursuant to which VFMCRP assumed JT’s rights in Rayaldee in Japan. Under the VFMCRP Agreement, as amended from time to time, we have a license and collaboration agreement for the development and commercialization of Rayaldee in Europe, Canada, Australia, and certain other international markets for the treatment of SHPT in patients with CKD and vitamin D insufficiency. In June 2021, we entered into a license agreement with Nicoya to distribute and sell Rayaldee in China and certain other countries. In July 2021, we licensed out our AntagoNAT portfolio owned by CURNA, INC. to CAMP4. In September 2021, we also entered into specific arrangements with LeaderMed in certain countries in Asia with respect to OPK-88003 and Factor VIIa. In November 2021, EirGen licensed out Rayaldee patent estate to Progenetics Ltd. to distribute Rayaldee in Israel. In December 2014, we entered into the Pfizer Transaction for the development and commercialization of our long-acting hGH-CTP for the treatment of GHD in adults and children, as well as for the treatment of growth failure in children born small for gestational age. Previously, we (or entities we have acquired) have completed strategic licensing transactions with the President and Fellows of Harvard College, Academia Sinica, The Scripps Research Institute, TESARO, INEOS Healthcare, and Arctic Partners, among others.

With regard to our pharmaceutical products, Rayaldee’s competition includes, among other products, activated (1-alpha-hydroxylated) vitamin D analogs such as calcitriol, doxercalciferol, and paricalcitol, and vitamin D supplements such as  ergocalciferol and cholecalciferol. Although we believe that Rayaldee offers substantial benefits over these products, Rayaldee may be competing with these and other lower priced products and products which are marketed by larger pharmaceutical companies with substantially greater resources.

We are commercializing our 4Kscore product in the U.S., Europe and Mexico in a laboratory setting and seek to capitalize on commercialization opportunities for our proprietary diagnostic point-of-care system by transitioning laboratory-based tests, including PSA and other tests to our point-of-care system. Competitors to our diagnostics business are many and include major diagnostic companies, molecular diagnostic firms, universities, and research institutions.

Pricing and reimbursement coverage positions could substantially impact the competitiveness of the 4Kscore test and our other diagnostic products. Our ability to commercialize our pharmaceutical and diagnostic test product candidates and compete effectively will depend, in large part, on:

•our ability to meet all necessary regulatory requirements to advance our product candidates through clinical trials and the regulatory approval process in the U.S. and abroad;

•the perception by physicians and other members of the health care community of the safety, efficacy, and benefits of our products compared to those of competing products or therapies;

•our ability to manufacture products we may develop on a commercial scale;

•the effectiveness of our sales and marketing efforts;

•the willingness of physicians to adopt a new diagnostic or treatment regimen represented by our technology;

•our ability to secure reimbursement for our product candidates;

•the price of the products we may develop and commercialize relative to competing products;

•our ability to accurately forecast and meet demand for our product candidates if regulatory approvals are achieved;

•our ability to develop a commercial scale infrastructure either on our own or with a collaborator, which would include expansion of existing facilities, including our manufacturing facilities, development of a sales and distribution network, and other operational and financial systems necessary to support our increased scale;

•our ability to maintain a proprietary position in our technologies; and

•our ability to rapidly expand the existing information technology infrastructure and configure existing operational, manufacturing, and financial systems (on our own or with third party collaborators) necessary to support our increased scale, which would include existing or additional facilities and or partners.

Other than NGENLA (Somatrogon), which has been approved in the EU, Japan, Canada and Australia, Rayaldee is our only pharmaceutical product under development that has been approved for marketing in the U.S. or elsewhere. We may not be able to obtain regulatory approval for any of our other products under development in a timely manner, if at all. Failure to obtain requisite governmental approvals or failure to obtain approvals of the scope requested will delay or preclude us, or our licensees or marketing partners, from marketing our products, or limit the commercial use of our products, and thereby would have a material adverse effect on our business, financial condition, and results of operations. See “Risk Factors — The results of pre-clinical trials and previous clinical trials for our products may not be predictive of future results, and our current and planned clinical trials may not satisfy the requirements of the FDA or other non-U.S. regulatory authorities.”

With the launch of Rayaldee, part of our business is now subject to the federal Physician Payments Sunshine Act under the Affordable Care Act, and its implementing regulations, which is implemented though the physicians Open Payments Program (the “Open Payments Program”). The Open Payments Program requires manufacturers of drugs, devices, biological and medical supplies covered by Medicare, Medicaid or the Children’s Health Insurance Program, to report information related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals. Manufacturers must also report, on an annual basis, certain ownership and investment interests held by physicians and their immediate family members and payments or other “transfers of value” made to such physician owners. A failure to report each payment, other transfer of value, or ownership/investment interest in a timely, accurate, and complete manner may result in civil monetary penalties of up to $150,000 annually. Further, the “knowing” failure to report each payment, other transfer of value, or ownership/investment interest may result in a one million dollar annual penalty. Several other states and a number of countries worldwide have adopted or are considering the adoption of similar transparency laws. Any failure by us to implement proper procedures to track and report on a timely basis transfers of value to physicians and teaching hospitals could result in substantial penalties.

Our diagnostics business includes BioReference’s almost 250-person sales and marketing team in the U.S. to drive growth and leverage new products. We have a highly specialized, field based 57-person sales and marketing team in the United States dedicated to the launch and commercialization of Rayaldee. We also have limited sales and marketing personnel in Ireland, Chile, Spain, Mexico and Israel.

As a company in the healthcare industry, employee safety is a key focus of our leadership, communications, and training. We are required to comply with the College of American Pathologists and CLIA laboratory safety requirements in addition to OSHA regulations. With a clear leader in our EHS Manager, direction, standards of practice, training and auditing are consolidated and then disseminated to our managers, supervisors and all employees. We continually align our health and safety goals with those prescribed by applicable regulatory agencies and balance these goals with the needs of our employees. During the COVID-19 pandemic, we transitioned non-essential workers from the office to working from home, and we optimized our essential worker stations in our laboratories and other key process areas to provide for appropriate sanitation, social distancing and other appropriate measures to address the risks of the pandemic. Using guidance provided by the CDC and OSHA among other agencies, we worked to ensure proper personal protective equipment, spacing, workstation design and information support were available to our essential employees who continued working in our offices and facilities during the pandemic.

Governments have implemented travel restrictions and quarantine policies which may have a material adverse economic effect on our business. Such restrictions may present challenges in connection with our laboratory business, our ability to successfully commercialize Rayaldee, our ability to manufacture pharmaceutical products in Ireland, Mexico, Spain, Chile and Israel, and our ability to continue clinical development of our product candidates. Further, if the spread of the coronavirus pandemic continues and our operations are adversely impacted, our ability to meet performance obligations under contracts may be impacted.

BioReference’s COVID-19 testing volume has positively impacted our profitability, but we had, prior to 2020, incurred losses since our inception. We may not continue to generate substantial revenue from COVID-19 testing as vaccine use is adopted and infection rates decline, unless such decline is offset by significant revenue generation from our other income streams. We have historically generated only limited revenue from operations and we may not generate substantial revenue from the sale of proprietary pharmaceutical products or certain of our diagnostic products for some time, if at all. Other than NGENLA (Somatrogon), which has been approved in the EU, Japan, Canada and Australia, Rayaldee is our only pharmaceutical product that has been approved for marketing in the U.S. or elsewhere. We continue to incur substantial research and development and general and administrative expenses related to our operations including our pre-clinical development activities and clinical trials. We may incur losses from our operations in the future and these losses could increase as we continue our research activities and conduct development of, and seek regulatory approvals and clearances for, our product candidates, particularly if we are unable to generate or sustain profits and cash flow from sales of Rayaldee, NGENLA,

or our operations at BioReference. If we are unable to generate or sustain profits and cash flow from our operations, our product candidates fail in clinical trials or do not gain regulatory approval or clearance, or if our approved products and product candidates do not achieve market acceptance, we may no longer be profitable. In particular, if we are unable to successfully commercialize Rayaldee or NGENLA, we may never generate substantial revenues from Rayaldee or NGENLA. If we are unable to obtain FDA approval for Somatrogon in the U.S., we will not be able to commercialize Somatrogon in the U.S. and will therefore not generate revenues from NGENLA in the U.S. In addition, if we are required by the FDA to perform studies in addition to those we currently anticipate, our expenses will increase beyond current expectations and the timing of any potential product approval may be delayed.

•be found to be ineffective, unreliable, or otherwise inadequate or otherwise fail to receive regulatory approval;

•be difficult or impossible to manufacture on a commercial scale;

•be uneconomical to market or otherwise not be effectively marketed;

•fail to be successfully commercialized if adequate reimbursement from government health administration authorities, private health insurers, and other organizations for the costs of these products is unavailable;

•be impossible to commercialize because they infringe on the proprietary rights of others or compete with products marketed by others that are superior; or

•fail to be commercialized prior to the successful marketing of similar products by competitors.

In May 2016, EirGen, our wholly-owned subsidiary, partnered with VFMCRP through a Development and License Agreement for the development and marketing of Rayaldee in Europe, Canada, Mexico, Australia, South Korea and certain other international markets. The license to VFMCRP potentially covers all therapeutic and prophylactic uses of the product in human patients, provided that initially the license is for the use of the product for the treatment or prevention of secondary hyperparathyroidism related to patients with stage 3 or 4 chronic kidney disease and vitamin D insufficiency/deficiency. Effective May 5, 2020, we entered into the VFMCRP Amendment, pursuant to which the parties agreed to exclude Mexico, South Korea, the Middle East and all of the countries of Africa from the VFMCRP Territory. In May 2021, we further amended the VFMCRP Agreement for VFMCRP to assume all the rights to Rayaldee in Japan that had been previously granted to JT. In addition, the parties agreed to certain amendments to the milestone structure and to reduce minimum royalties payable. As revised, the Company is eligible to receive up to $17 million in regulatory milestones and $210 million in milestone payments tied to launch, pricing and sales of Rayaldee, and tiered, double-digit royalties. The success of the Development and License Agreement with VFMCRP is dependent in part on, among other things, the skills, experience and efforts of VFMCRP’s employees responsible for the project, VFMCRP’s commitment to the arrangement, and the financial condition of VFMCRP, all of which are beyond our control. In the event that VFMCRP, for any reason, including but not limited to early termination of the agreement, fails to devote sufficient resources to successfully develop and market Rayaldee internationally, our ability to earn milestone payments or receive royalty payments would be adversely affected, which would have a material adverse effect on our financial condition and prospects.

In October 2017, we entered into a Development and License Agreement (the “JT Agreement”) with JT under which JT was granted the exclusive rights for the development and commercialization of Rayaldee in Japan. The JT Agreement was terminated in May 2021.

In December 2014, we entered into a development and commercialization agreement with Pfizer relating to our long-acting hGH- CTP for the treatment of GHD in adults and children (the “Pfizer Agreement”). Under the Pfizer Agreement, we are eligible to receive up to $275 million upon the achievement of certain regulatory milestones. Upon the launch of Somatrogon (hGH-CTP) for pediatric GHD, we are eligible to receive a regional, tiered gross profit share based upon sales of both Somatrogon and Pfizer’s Genotropin® (somatropin). We are responsible for the development program and are obligated to pay for the development up to an agreed cap, which has been exceeded. In May 2020, we entered into an Amended and Restated Development and Commercialization License Agreement (the “Restated Pfizer Agreement”) with Pfizer, effective January 1, 2020, pursuant to which the parties agreed, among other things, to share all costs for Manufacturing Activities, as defined in the Restated Pfizer Agreement, for developing a licensed product for the three indications included in the Agreement. While hGH-CTP has been approved in the EU, Japan, Canada and Australia under the name NGENLA, Pfizer received a Complete Response Letter from the FDA in January 2022 in response to the BLA we and Pfizer submitted in 2020. We and Pfizer are evaluating the FDA’s comments and will work with the agency to determine an appropriate path forward. In the event that the parties are able to obtain regulatory approvals to market a product covered by the Pfizer Agreement, we will be substantially dependent on Pfizer for the successful commercialization of such product. The success of the collaboration arrangement with Pfizer is dependent in part on, among other things, the skills, experience and efforts of Pfizer’s employees responsible for the project and Pfizer’s commitment to the arrangement. The Pfizer Agreement is terminable for any reason by Pfizer upon ninety days written notice to OPKO. In the event that Pfizer terminates the Agreement or fails to devote sufficient resources to successfully develop and commercialize any product resulting from the collaboration arrangement, our ability to earn milestone payments or receive royalty or profit sharing payments would be adversely affected, which would have a material adverse effect on our financial condition and prospects and the trading prices of our securities.

Our business is dependent on our ability to successfully commercialize our diagnostic products. We are committing significant resources to the development and commercialization of these products, and there is no guarantee that we will be able to successfully commercialize these tests. We have limited experience in developing, manufacturing, selling, marketing and distributing innovative diagnostic tests. If we are not able to successfully develop, market or sell diagnostic tests we develop for any reason, including the failure to obtain any required regulatory approvals, or obtain favorable reimbursement, we will not generate any meaningful revenue from the sale of such tests.

Our business is substantially dependent on our ability to generate profits and cash flow from our laboratory operations.

We have made a significant investment in our laboratory operations through the acquisition of BioReference. We compete in the clinical laboratory market primarily on the basis of the quality of testing, reporting and information systems, reputation in the medical community, the pricing of services and ability to employ qualified personnel. Our failure to successfully compete on any of these factors could result in the loss of clients and a reduction in our revenues and profits. To offset efforts by payors to reduce the cost and utilization of clinical laboratory services, we will need to obtain and retain new clients and business partners and grow the laboratory operations. In response to the global pandemic, BioReference has been conducting a substantial amount of COVID-19 testing that has positively impacted our revenues. Simultaneously, however, the volume of its core testing business has decreased as a result of COVID-19. A significant reduction in COVID-19 tests ordered, specimens submitted by existing clients, or payment rates, without offsetting growth in our core business testing or client base,

•a limited number of, and competition for, suitable patients with the particular types of disease required for enrollment in our clinical trials or that otherwise meet the protocol’s inclusion criteria and do not meet any of the exclusion criteria;

•a limited number of, and competition for, suitable serum or other samples from patients with particular types of disease required for our validation studies;

•a limited number of, and competition for, suitable sites to conduct our clinical trials;

•delay or failure to obtain FDA or other non-U.S. regulatory authorities’ approval or agreement to commence a clinical trial;

•delay or failure to obtain sufficient supplies of the product candidate for our clinical trials;

•requirements to provide the drugs, diagnostic tests, or medical devices required in our clinical trial protocols or clinical trials at no cost or cost, which may require significant expenditures that we are unable or unwilling to make;

•delay or failure to reach agreement on acceptable clinical trial agreement terms or clinical trial protocols with prospective sites or investigators;

•delay or failure to obtain institutional review board (“IRB”) approval to conduct or renew a clinical trial at a prospective site; and

•insufficient liquidity to fund our preclinical and clinical studies.

•slower than expected rates of patient recruitment and enrollment;

•failure of patients to complete the clinical trial;

•unforeseen safety issues;

•lack of efficacy evidenced during clinical trials;

•termination of our clinical trials by one or more clinical trial sites;

•inability or unwillingness of patients or medical investigators to follow our clinical trial protocols;

•inability to monitor patients adequately during or after treatment; and

•insufficient liquidity to fund ongoing studies.

•timing of market introduction of competitive products;

•safety and efficacy of our product compared to other products;

•prevalence and severity of any side effects;

•potential advantages or disadvantages over alternative treatments;

•strength of marketing and distribution support;

•price of our products, both in absolute terms and relative to alternative treatments;

•availability of coverage and reimbursement from government and other third-party payors;

•potential product liability claims;

•limitations or warnings contained in a product’s regulatory authority-approved labeling; and

•changes in the standard of care for the targeted indications for any of our products or product candidates, which could reduce the marketing impact of any claims that we could make following applicable regulatory authority approval.

One aspect of our business strategy calls for acquisitions of businesses and assets that complement or expand our current business and potential disposition of assets and businesses that may no longer help us meet our objectives, which may present greater risks for us than those faced by peer companies that do not consider acquisitions or dispositions as a part of their business strategy. We may not be able to identify attractive acquisition opportunities or, when we decide to sell assets or a business, we may encounter difficulty in finding buyers or alternative exit strategies on acceptable terms in a timely manner, or at all. Even if we do identify attractive opportunities, we or the buyer may not be able to complete the acquisition due to financing or other market constraints. If we acquire an additional business, we could have difficulty integrating its operations, systems, management and other personnel and technology with our own. There may also be unasserted claims or assessments that we failed or were unable to discover or identify in the course of performing due diligence investigations of target businesses, resulting in a loss of value. Dispositions may increase our exposure to third parties claims or litigation that may require expenditure of additional resources or negatively affect the successful outcome of the disposition. Dispositions may also involve continued financial involvement in the divested business, such as through guarantees, indemnities or other financial obligations. Under these arrangements, performance by the divested businesses or other conditions outside of our control could affect our future financial results. Moreover, seeking acquisition and divestiture opportunities and evaluating and completing them require significant investment of time and resources, may disrupt the Company’s business and distract management’s attention from day-to-day business operations.

In addition to our internal information technology systems, we rely on the IT systems of certain third parties to whom we outsource certain of our services or functions, or with whom we store confidential information, including patient data. These IT systems are subject to potential cyberattacks or other security breaches. If such attacks are successful, they could disrupt our operations and result in unauthorized persons gaining access to confidential or proprietary information. A breach or security incident affecting these third parties could harm our business, results of operations and reputation, and subject us to liability, governmental investigation, significant damage to our reputation or otherwise adversely affect our business.

Although the Company has security measures implemented, cyber-attacks and threats against us and our third-party providers continue to evolve and are often not recognized until such attacks are launched against a potential target. A successful cybersecurity attack or other data security incident could result in the misappropriation and/or loss of confidential or personal information, create system interruptions, or deploy malicious software that attacks our systems. The unauthorized dissemination of sensitive personal information or proprietary or confidential information due to a breach of these IT systems could expose us or other third-parties to regulatory fines or penalties, litigation and potential liability, or otherwise harm our business. Any mitigation or remediation efforts that we undertake may require expenditures of significant resources and the diversion of the attention of management. In addition, we have taken, and continue to take, precautionary measures to reduce the risk of, and detect and respond to, future cyber threats, and prevent or minimize vulnerabilities in our IT systems. We have also taken, and will continue to take, measures to assess the cybersecurity protections implemented by our third-party providers. There can be no assurances that our precautionary measures or measures used by our third-party providers will prevent, contain or successfully defend against cyber or information security threats that could have a significant impact on our business, results of operations and reputation and subject us to liability.

It is possible that in the patent laws related to the field of genomic-based products and diagnostics and patents covering such products changes to permit the patenting of genes and/or gene based products and/or related diagnostic methods. In such a case, we might be required to pay royalties, damages and costs to firms who own the rights to these patents, or we might be restricted from using any of the inventions claimed in those patents.

The research, testing, manufacturing, labeling, approval, selling, marketing, and distribution of drug products, diagnostic products, or medical devices are subject to extensive regulation by the FDA and other non-U.S. regulatory authorities, which regulations differ from country to country. In general, we are not permitted to market our product candidates in the U.S. until we receive approval of a BLA, an approval of an NDA, a clearance letter under the premarket notification process, or 510(k) process, or an approval of a PMA from the FDA. To date, we have only submitted one NDA which was approved in June 2016, and one BLA which was approved for filing in January 2021. We have received FDA approval of the PMA for our Sangia Total PSA Test using the Claros Analyzer, a novel diagnostic instrument system to provide rapid, high performance blood test results in the point-of-care setting, in January 2019 and, in December 2021, for our 4Kscore test for use in men age 45 and older who have not had a prior prostate biopsy or are biopsy negative and have an age-specific abnormal total PSA and/or abnormal digital rectal exam, but we have not received marketing approval or clearance for any of our other diagnostic product candidates. In response to the BLA we submitted for Somatrogon Pfizer received a Complete Response Letter, which we and Pfizer are reviewing to determine the best path forward for Somatrogon. Obtaining approval of a NDA or PMA can be a lengthy, expensive, and uncertain process. With respect to medical devices, while the FDA reviews and clears a premarket notification in as little as three months, there is no guarantee that our products will qualify for this more expeditious regulatory process, which is reserved for Class I and II devices, nor is there any assurance that even if a device is reviewed under the 510(k) process that the FDA will review it expeditiously or determine that the device is substantially equivalent to a lawfully marketed non-PMA device. If the FDA fails to make this finding, then we cannot market the device. In lieu of acting on a premarket notification, the FDA may seek additional information or additional data which would further delay our ability to market the product. Furthermore, we are not permitted to make changes to a device approved through the PMA or 510(k) which affects the safety or efficacy of the device without first submitting a supplement application to the PMA and obtaining FDA approval or cleared premarket notification for that supplement. In some cases, the FDA may require clinical trials to support a supplement application. In addition, failure to comply with FDA, non-U.S. regulatory authorities, or other applicable U.S. and non-U.S. regulatory requirements may, either before or after product approval or clearance, if any, subject our company to administrative or judicially imposed sanctions, including, but not limited to the following:

▪restrictions on the products, manufacturers, or manufacturing process;

▪adverse inspectional observations (Form 483), warning letters, or non-warning letters incorporating inspectional observations;

▪civil and criminal penalties;

▪injunctions;

▪suspension or withdrawal of regulatory approvals or clearances;

▪product seizures, detentions, or import bans;

▪voluntary or mandatory product recalls and publicity requirements;

▪total or partial suspension of production;

▪imposition of restrictions on operations, including costly new manufacturing requirements; and

▪refusal to approve or clear pending NDAs or supplements to approved NDAs, applications or pre-market notifications.

▪a drug candidate may not be deemed safe or effective;

▪a medical device candidate may not be deemed to be substantially equivalent to a lawfully marketed non-PMA device, in the case of a premarket notification;

▪the FDA may not find the data from pre-clinical studies and clinical trials sufficient;

▪the FDA may not approve our or our third-party manufacturer’s processes or facilities; or

▪the FDA may change its approval or clearance policies or adopt new regulations.

We may also be required to comply with the data privacy and security laws of other countries in which we operate or from which we receive data transfers, including the General Data Protection Regulation (GDPR), which affects our European operations and possibly our laboratory and clinical development operations. The GDPR, which is wide-ranging in scope, governs the collection and use of personal data in the European Union and imposes operational requirements for companies that receive or process personal data of residents of the European Union that are different than those currently in place in the European Union. We have implemented policies and procedures required to comply with the new EU regulations but may be subject for penalties if we are found to be non-compliant.

Sales of Rayaldee and our operations at EirGen, are currently underperforming expectations and if we do not achieve our planned operating results, we may be required to incur a non-cash impairment charge. There can be no assurance that future reviews of our goodwill and other intangible assets will not result in impairment charges. Any impairment charges in the future will adversely affect our results of operations. A significant write down of goodwill and/or other intangible assets would have a material adverse effect on our reported results of operations and net worth and the trading price of our securities.

Between October 2018 and January 2019, five shareholder derivative complaints were filed by purported stockholders in the Delaware Court of Chancery against the Company as a nominal defendant, Dr. Frost and the Company’s Board of Directors. In the first quarter of 2019, the five lawsuits were consolidated into In re OPKO Health, Inc. Derivative Action, Case No. 2018-0740-SG (the “Consolidated Delaware Action”). On February 11, 2019, a Verified Consolidated Derivative Complaint was filed in the Consolidated Delaware Action, and Richard Tunick, Jamie Gewirtz, Emily Gewirtz Stiebel, Esther Susan Lutzker and Ivan Pawlenko were named as Co-Lead Plaintiffs in the filing. The Consolidated Derivative Complaint alleged breach of fiduciary duty based on the allegations raised by the SEC in the SEC Complaint, and breach of the duty of loyalty. The lead plaintiffs sought to declare the action a proper derivative action, monetary damages, disgorgement of all remuneration during the relevant time period, to direct the Company to improve its internal controls, equitable and injunctive relief, pre- and post-judgment interest, an award of reasonable attorneys’ fees and expert fees, and such other relief as the Court deemed just and proper. The Settlement was approved on November 2, 2020.
