WALTHAM, Mass., November 2, 2017 -- Radius Health, Inc. ("Radius" or the "Company") (Nasdaq:RDUS), today reported its financial results for the third quarter ended September 30, 2017, and provided a business update.

“It is very encouraging for Radius to see TYMLOS gaining traction in the market," said Jesper Høiland, President and CEO of Radius. "In addition to our stated goal of gaining market leadership for TYMLOS, we are excited by the positive response to the product by physicians, payors and patients. With the recent capital raise, we are also well funded to start investing in expanding the TYMLOS label and advancing the development of our other therapeutic candidates in the pipeline."

"TYMLOS is proving itself to be an important treatment for a high unmet medical need, as demonstrated by the continued increase in lives covered through managed care contracts," said David Snow, Chief Commercial Officer of Radius. "Postmenopausal women with osteoporosis at high risk for fractures deserve to have therapies that safely and effectively reduce that risk, with lower out of pocket costs. Our sales team is achieving strong reach and call frequency and we are continuing to expand payer acceptance while we see anabolic class volume stabilizing."

Pipeline Updates

Abaloparatide – Subcutaneous (SC)

Radius' European Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of postmenopausal women with osteoporosis is under review by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA). On July 21, 2017, the CHMP issued a second Day-180 List of Outstanding Issues. Radius is working with the CHMP to address these issues, and discussed preliminary responses with the Rapporteurs in a formal Clarification Meeting. We expect an opinion from the CHMP regarding the MAA prior to the end of 2017.

We recently gained agreement with the FDA on the design of a clinical trial in men with osteoporosis, which, if successful, will form the basis of an sNDA seeking to expand the use of TYMLOS to treat men with osteoporosis at high risk for fracture. The study will be a randomized, double-blind, placebo-controlled trial that will enroll approximately 225 men with osteoporosis.

The primary endpoint is change in spine bone mineral density (“BMD”) at 12 months compared with placebo. TYMLOS has demonstrated in previous clinical trials that it increases BMD in postmenopausal women. The study will include specialized high-resolution imaging of bone structure in a subset of the study participants. We expect to initiate the trial in the first quarter of 2018.

Elacestrant (RAD1901)

Elacestrant is also being evaluated at low doses as an estrogen receptor ligand for the potential relief of the frequency and severity of moderate to severe hot flashes in postmenopausal women with vasomotor symptoms. We are currently reviewing our elacestrant vasomotor development program and plan to provide an update by the end of 2017.

Third Quarter 2017 Financial Results

Three Months Ended September 30, 2017

For the three months ended September 30, 2017, Radius reported a net loss of $57.8 million, or $1.31 per share, compared to a net loss of $46.2 million, or $1.07 per share, for the three months ended September 30, 2016.

For the three months ended September 30, 2017, Radius reported TYMLOS net product revenues of about $3.5 million, which reflects the first full quarter of recorded sales. Radius had no revenue in the three months ended September 30, 2016 as the FDA approved TYMLOS on April 28, 2017.

5

Research and development expense for the three months ended September 30, 2017, was $21.0 million compared to $27.5 million for the three months ended September 30, 2016, a decrease of $6.5 million, or 24%.  This decrease was primarily driven by a $3.4 million decrease in vasomotor project related spending, a $2.0 million decrease in abaloparatide-SC project costs, and a $1.1 million decrease in RAD1901 oncology project costs.

Selling, general, and administrative expense for the three months ended September 30, 2017, was $47.7 million compared to $19.2 million for the three months ended September 30, 2016, an increase of $28.5 million, or 148%. This increase was primarily the result of an increase of approximately $10.1 million in professional fees and support costs, including the costs associated with increasing headcount and preparing for the commercialization of TYMLOS in the United States. This increase was also driven by a $15.2 million increase in compensation expense, including stock-based compensation, due to the increase in headcount.

Nine Months Ended September 30, 2017

For the nine months ended September 30, 2017, Radius reported a net loss of $183.2 million, or $4.21 per share, compared to a net loss of $130.1 million, or $3.02 per share, for the nine months ended September 30, 2016.

For the nine months ended September 30, 2017 Radius reported TYMLOS net product revenues of about $4.4 million, which reflects the first full quarter of reported sales. Radius had no revenue in the nine months ended September 30, 2016 as the FDA approved TYMLOS on April 28, 2017.

Research and development expense for the nine months ended September 30, 2017, was $60.2 million compared to $81.8 million for the nine months ended September 30, 2016, a decrease of $21.6 million, or 26%.  This decrease was primarily driven by a $14.9 million decrease in RAD1901 project costs, a $14.1 million decrease in abaloparatide-SC project costs, and a $2.2 million decrease in development costs associated with abaloparatide-TD. This decrease was partially offset by a $9.7 million increase in compensation expense, including stock-based compensation, due to an increase in headcount.

Selling, general, and administrative expense for the nine months ended September 30, 2017, was $135.9 million compared to $50.1 million for the nine months ended September 30, 2016, an increase of $85.8

6

million, or 171%. This increase was primarily the result of an increase of approximately $27.9 million in professional fees and support costs during the nine months ended September 30, 2017, including the costs associated with increasing headcount and preparing for the commercialization of TYMLOS in the United States. This increase was also driven by a $49.4 million increase in compensation expense, including stock-based compensation, due to an increase in headcount.

As of September 30, 2017, Radius had $468.1 million in cash, cash equivalents and marketable securities. Based upon our cash, cash equivalents and marketable securities balance as of September 30, 2017, we believe that, prior to the consideration of proceeds from partnering and/or collaboration activities, we have sufficient capital to fund our development plans, U.S. commercial and other operational activities for not less than twelve months from the date of this press release.

For more information, please visit www.radiuspharm.com.

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. Radius' Marketing Authorisation Application (MAA) for abaloparatide-SC for the treatment of women with postmenopausal osteoporosis was validated and is currently undergoing regulatory review by the European Medicines Agency (EMA).

Radius also is developing abaloparatide-transdermal (abaloparatide-TD) based on 3M Company's patented Microstructured Transdermal System technology for potential use as a treatment for postmenopausal women with osteoporosis.

About ACTIVE and ACTIVExtend

The Phase 3 ACTIVE (Abaloparatide Comparator Trial In Vertebral Endpoints) trial was a randomized, double-blind, placebo-controlled, comparative, multicenter, 18 month international study in 2,463 postmenopausal women with osteoporosis designed to evaluate the efficacy and safety of abaloparatide-SC 80 mcg to reduce the risk of vertebral and nonvertebral fractures. The results of ACTIVE were published in the Journal of the American Medical Association in August of 2016. ACTIVExtend, an extension of ACTIVE, enrolled patients who had completed 18 months of abaloparatide-SC or placebo in ACTIVE to receive up to 24 additional months of open-label alendronate. The results of the first six months of ACTIVExtend were published in the Mayo Clinic Proceedings in February of 2017.

About Elacestrant (RAD1901)

11

Elacestrant is a selective estrogen receptor degrader (SERD), which is being evaluated for potential use as a once daily oral treatment for hormone-receptor positive breast cancer. Elacestrant is currently being investigated for potential use in women with advanced estrogen receptor positive, HER2 negative, breast cancer, the most common form of the disease. Studies completed to date indicate that the compound has the potential for use as a single agent or in combination with other therapies for the treatment of breast cancer.

Additional information on the clinical trial program of elacestrant (RAD1901) is available on www.clinicaltrials.gov.

About RAD140

RAD140 is a non-steroidal selective androgen receptor modulator (SARM). The androgen receptor (AR) is frequently expressed in many estrogen receptor (ER)-positive, ER-negative, and triple-negative breast cancers. Because of its receptor and tissue selectivity, potent activity, oral bioavailability, and long half-life, RAD140 could have clinical potential in the treatment of breast cancer. RAD140 resulted from an internal drug discovery program focused on the androgen receptor pathway, and exhibits a differentiated mechanism of action compared to ER-targeted therapy.
