Fourth Quarter & Full Year 2021 Results

Boston, Mass., February 24, 2022 – Radius Health, Inc. (“Radius” or the “Company”) (Nasdaq: RDUS), today reported its financial results for the fourth quarter and full year ended December 31, 2021 and provided key business and financial objectives for 2022.

CEO Kelly Martin provided the following commentary, “2022 is – absolutely – a pivot year for the company. 2021 saw the output around the multi-pronged strategy that had been set forth in 2017/18. Pivotal trial readouts for elacestrant as well as the abaloparatide male indication and the transdermal system provided point in time trial data clarity. The TYMLOS U.S. business improved in terms of productivity and product profitability, and, in the Japan market, which is the one of the largest anabolic markets, TYMLOS was approved.”

Martin added further, “Key elements to the pivot year of 2022 and beyond, including business philosophy and approach, are: (1) return of capital: 100% of all elacestrant proceeds, including net royalties and milestones will go directly to creditors and shareholders through debt paydown, share buy backs and/or dividends, (2) attain and maintain earnings – Cash EPS – on a full year basis, (3) crystalize the value of the previously generated $1.7 billion in NOLs for the company through the P+L, asset sale(s), or both, (4) focus on TYMLOS U.S. business: grow net revenue, improve productivity, patient conversion, and duration on therapy, and (5) prepare RAD011 pivotal trials for advancements recognizing market values recently ascribed to orphan neuro and epilepsy assets.”

Martin concluded by highlighting, “The recent market dislocation for biotechnology and biopharmaceutical company values has been significant. Our view is that capital markets will remain uncertain – for this sector and in terms of values and funding – for the foreseeable future. Within this challenging environment Radius has the opportunity to differentiate itself. Three distinct and valuable assets, $100+ million in cash and a manageable balance sheet, improving margins as well as the prospects of generating cash flow all comprise a strong foundation to create value for shareholders and other stakeholders.”

Neuroscience: RAD011

The work of our neuroscience team is centered around the clinical development of our investigational synthetic cannabidiol oral solution (RAD011), which has potential utilization in multiple orphan neurological disease areas.

We plan to initiate, on a gated basis, three pivotal clinical trials in Prader Willi syndrome (PWS), with the goal of reducing hyperphagia, Angelman syndrome (AS), with the goal of reducing seizures, and Infantile Spasms (IS), with the goal of spasm resolution. RAD011 has been granted Orphan Drug Designation by the FDA for the treatment of PWS, AS, and IS.

We plan to host an R&D day focused on RAD011 in Q2 this year.

Use of Non-GAAP Financial Measures

To supplement our condensed consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles in the United States (GAAP), we use the following non-GAAP financial measures in this press release: Adjusted EBITDA and Adjusted EBITDA per share. The Company defines adjusted EBITDA as net income before interest, taxes, depreciation and amortization, adjusted for the impact of certain additional non-cash and other items that management does not consider in its evaluation of ongoing performance of the Company’s core operations. These items include stock-based compensation expense and other one-time expenses. These non-GAAP financial measures exclude certain amounts or expenses from the corresponding financial measures determined in accordance with GAAP. Management believes this non-GAAP information is useful for investors, taken in conjunction with Radius’ GAAP financial statements, because it provides greater transparency and period-over-period comparability with respect to Radius’ operating performance and can enhance investors’ ability to identify operating trends in our business. Management uses these measures, among other factors, to assess and analyze operational results and trends and to make financial and operational decisions. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of Radius’ operating results as reported under GAAP, not in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with GAAP. In addition, these non-GAAP financial measures are unlikely to be comparable with non-GAAP information provided by other companies. The determination of the amounts that are excluded from non-GAAP financial measures is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts. Reconciliations between these non-GAAP financial measures and the most comparable GAAP financial measures for the three and twelve months ended December 31, 2021 and 2020 are included in the tables accompanying this press release after the unaudited condensed consolidated financial statements.

This release includes forward-looking guidance for adjusted EBITDA. The Company is not able to provide, without unreasonable effort, a reconciliation of the guidance for adjusted EBITDA to the most directly comparable GAAP measure because the Company does not currently have sufficient data to accurately estimate the variables and individual adjustments included in the most directly comparable GAAP measure that would be necessary for such reconciliations, including (a) one-time items or other expenses that we do not believe are indicative of our ongoing operations. These adjustments are inherently variable and uncertain and depend on various factors that are beyond our control and as a result we are also unable to predict their probable significance. Therefore, because management cannot estimate on a forward-looking basis without unreasonable effort the impact these variables and individual adjustments will have on its reported results in accordance with GAAP, it is unable to provide a reconciliation of the non-GAAP measures included in its 2022 guidance.

About Radius

Radius is a global biopharmaceutical company focused on addressing unmet medical needs in the areas of bone health, orphan diseases, and oncology. Radius’ lead product, TYMLOS® (abaloparatide) injection, was approved by the U.S. Food and Drug Administration for the treatment of postmenopausal women with osteoporosis at high risk for fracture. The Radius clinical pipeline includes investigational abaloparatide injection for potential use in the treatment of men with osteoporosis; an investigational abaloparatide transdermal system for potential use in the treatment of postmenopausal women with osteoporosis; the investigational drug, elacestrant (RAD1901), for potential use in the treatment of hormone-receptor positive breast cancer out-licensed to Menarini Group; and the investigational drug RAD011, a synthetic cannabidiol oral solution with potential utilization in multiple endocrine, neurological, and metabolic orphan diseases, initially targeting Prader-Willi syndrome, Angelman syndrome, and Infantile Spasms.

About TYMLOS (abaloparatide) injection
TYMLOS (abaloparatide) injection was approved by the U.S. Food and Drug Administration for the treatment of postmenopausal women with osteoporosis at high risk for fracture defined as history of osteoporotic fracture, multiple risk factors for fracture, or patients who have failed or are intolerant to other available osteoporosis therapy.

About ATOM Phase 3 Study

The ATOM Phase 3 study is a randomized, double-blind, placebo-controlled study to assess efficacy and safety of abaloparatide injection in 228 men with osteoporosis. The primary endpoint is change in lumbar spine BMD at 12 months compared with placebo, and it is expected to form the basis of a supplemental NDA seeking to expand the use of TYMLOS to treat men with osteoporosis at high risk for fracture.

About the Abaloparatide Transdermal System and wearABLe Phase 3 Study

The abaloparatide transdermal system was developed in a collaboration between Radius and Kindeva Drug Delivery (“Kindeva”) (formerly 3M Drug Delivery Systems) with the application of Kindeva’s innovative microstructured transdermal system technology. The wearABLe study is a pivotal, randomized, open label, active-controlled, bone mineral density (“BMD”) non-inferiority bridging study to evaluate the efficacy and safety of abaloparatide transdermal system versus TYMLOS (abaloparatide) injection in approximately 500 patients with postmenopausal osteoporosis at high risk for fracture. The primary endpoint of the study is the percentage change in lumbar spine BMD at 12 months.

About Elacestrant (RAD1901) and EMERALD Phase 3 Study

Elacestrant is a selective estrogen receptor degrader (SERD), out-licensed to Menarini Group, which is being evaluated for potential use as a once daily oral treatment in patients with ER+/ HER2- advanced breast cancer. Studies completed prior to EMERALD indicate that the compound has the potential for use as a single agent or in

9

combination with other therapies for the treatment of breast cancer. The EMERALD Phase 3 trial is a randomized, open label, active-controlled study evaluating elacestrant as second- or third-line monotherapy in ER+/HER2- advanced/metastatic breast cancer patients. The study has enrolled 466 patients who have received prior treatment with one or two lines of endocrine therapy, including a cyclin-dependent kinase (CDK) 4/6 inhibitor. Patients in the study were randomized to receive either elacestrant or the investigator’s choice of an approved hormonal agent. The primary endpoint of the study is progression-free survival (PFS) in the overall patient population and in patients with estrogen receptor 1 gene (ESR1) mutations. Secondary endpoints include evaluation of overall survival (OS), objective response rate (ORR), and duration of response (DOR).

About RAD011

Investigational drug RAD011 is a pharmaceutical-grade synthetic cannabidiol oral solution, manufactured utilizing traditional pharmaceutical manufacturing processes. The product has purity specifications that meet standardized regulatory and quality control requirements and, compared to the process of developing a plant-derived product, the synthetic manufacturing process usually enables increased consistency and greater precision in the product supply. RAD011 has been assessed in over 125 patients across multiple indications and has potential utilization in multiple endocrine, neurological, and metabolic orphan diseases. Radius anticipates initiating a seamless pivotal Phase 2/3 study for patients with Prader-Willi syndrome in the first quarter of 2022 as well as pivotal studies for patients with Angelman syndrome and Infantile Spasms.
