Corporate & Financial Highlights

Rare Neuromuscular Franchise: KEVEYIS^® (dichlorphenamide)

• The Company achieved KEVEYIS net product sales of $8.4 million for the first quarter ended March 31, 2021, representing a 25 percent increase over first quarter 2020 revenue of $6.7 million. Sales momentum continued in April with KEVEYIS delivering the highest month of net product sales since its launch by the Company in 2017.
  • First quarter performance is attributed to the growth in patients on drug, resulting from new patient starts combined with improved discontinuation rates for existing patients on therapy.
• In April, a case report concerning a patient with Andersen-Tawil Syndrome switching from acetazolamide to KEVEYIS was presented at the American Academy of Neurology (AAN) virtual meeting. This case report was also recently published in the peer-reviewed journal Neuromuscular Disorders.

First Quarter 2021 Financial Results
The Company’s net revenues from sales of KEVEYIS increased $1.7 million, or 25 percent, to $8.4 million for the three months ended March 31, 2021 compared to $6.7 million for the three months ended March 31, 2020. The Company recorded cost of sales of $0.4 million for the three months ended March 31, 2021, compared to cost of sales of $1.0 million for the same period in 2020. Cost of sales decreased due to changes in the assumptions underlying the allocation between the purchase price of our inventory and our supply agreement. Gross margins were 95 percent for three months ended March 31, 2021, compared to gross margins of 85 percent for the same period in 2020.

Selling, general and administrative expenses were $10.9 million for the three months ended March 31, 2021, compared to $10.4 million for the same period in 2020. The increase during the current period was primarily due to an increase in our non-cash stock compensation expense.

Research and development expenses were $5.8 million for the three months ended March 31, 2021, compared to $7.6 million for the same period in 2020. The decrease was primarily due to decreases in costs associated with our LOGICS and OPTICS trials, offset by increases in regulatory costs associated with our NDA submission.

For the three months ended March 31, 2021, basic net loss attributable to ordinary shareholders on a GAAP basis was ($11.8 million), or ($0.18) per share, compared to a basic net loss attributable to ordinary shareholders of ($12.7) million, or ($0.23) per share, for the same period in 2020. Net loss for the three months ended March 31, 2021 was lower than the same period in 2020 due to the increase in KEVEYIS revenue of $1.7 million, the improvement in gross margin and the reduction in research and development expenses. Those decreases were offset by $0.8 million of interest expense recorded in the three months ended March 31, 2021, and a $1.4 million change in the revaluation of the fair value of our liability classified warrants due to the increase in the Company’s stock price in 2021 compared to 2020.

For the three months ended March 31, 2021, non-GAAP basic net loss attributable to ordinary shareholders was ($7.2 million), or ($0.11) per share, compared to a non-GAAP basic net loss attributable to ordinary shareholders of ($10.3 million), or ($0.19) per share, for the same period in 2020. The decrease in non-GAAP net loss during the three months ended March 31, 2021 was primarily due to an increase in KEVEYIS revenue of $1.7 million and improvement in gross margin. In addition, research and development expenses decreased during the three months ended March 31, 2021 compared to the same period in 2020 offset by cash interest expense in the three months ended March 31, 2021.

About Strongbridge Biopharma
Strongbridge Biopharma is a global commercial-stage biopharmaceutical company focused on the development and commercialization of therapies for rare diseases with significant unmet needs. Strongbridge’s rare endocrine franchise includes RECORLEV^® (levoketoconazole), an adrenal steroidogenesis inhibitor, currently being studied in Phase 3 clinical studies for the treatment of endogenous Cushing’s syndrome, and veldoreotide extended release, a preclinical next-generation somatostatin analog being investigated for the treatment of acromegaly and potential additional applications in other conditions amenable to somatostatin receptor activation. Both RECORLEV and veldoreotide have received orphan drug designation from the FDA and the European Medicines Agency. The Company’s rare neuromuscular franchise includes KEVEYIS^® (dichlorphenamide), the first and only FDA-approved treatment for hyperkalemic, hypokalemic, and related variants of primary periodic paralysis. KEVEYIS has orphan drug exclusivity in the United States.

About RECORLEV
RECORLEV^® (levoketoconazole) is an investigational adrenal steroidogenesis inhibitor in development for the treatment of patients with endogenous Cushing’s syndrome, a rare but serious and potentially lethal endocrine disease caused by chronic elevated cortisol exposure. RECORLEV is the pure 2S,4R enantiomer of ketoconazole, a steroidogenesis inhibitor. RECORLEV has demonstrated in two successful Phase 3 studies to significantly suppress serum cortisol and has the potential to be a next-generation cortisol inhibitor.

The Phase 3 program for RECORLEV includes SONICS and LOGICS: two multinational studies designed to evaluate the safety and efficacy of RECORLEV when used to treat endogenous Cushing’s syndrome. The SONICS study met its primary and secondary endpoints, demonstrating a statistically significant normalization rate of urinary free cortisol at six months. The LOGICS study, which met its primary endpoint and key secondary endpoint, is a double-blind, placebo-controlled randomized-withdrawal study of RECORLEV that is designed to supplement the long-term efficacy and safety information supplied by SONICS. The ongoing long-term open label OPTICS study will gather further useful information related to the long-term use of RECORLEV.

RECORLEV has received orphan drug designation from the FDA and the European Medicines Agency for the treatment of endogenous Cushing’s syndrome.

About KEVEYIS
KEVEYIS^® (dichlorphenamide) is indicated for the treatment of primary hyperkalemic periodic paralysis, primary hypokalemic periodic paralysis, and related variants. In clinical studies, the most common side effects of KEVEYIS were a numbness or tingling, difficulty thinking and paying attention, changes in taste, and confusion. These are not all of the possible side effects that you may experience with KEVEYIS. Talk to your doctor if you have any symptoms that bother you or do not go away.
