Hyperion Therapeutics Announces Fourth Quarter and Full Year 2013 Financial Results

Total 2013 Net Revenue of $42.2 Million; Fourth Quarter Net Sales of $18.6 Million, Including 46 Percent Growth in RAVICTI Sales

BRISBANE, Calif., Feb. 27, 2014 (GLOBE NEWSWIRE) -- Hyperion Therapeutics, Inc. (Nasdaq:HPTX) today reported net revenue of $18.6 million and $42.2 million for the fourth quarter and full year 2013, respectively. Hyperion's revenues are for sales of its two products for the treatment of urea cycle disorders, RAVICTI^® (glycerol phenylbutyrate) Oral Liquid, launched on March 1, 2013 and BUPHENYL^® (sodium phenylbutyrate) Tablets and Powder acquired on May 31, 2013. Adjusted net income for the fourth quarter 2013 was $4.1 million compared to an adjusted net loss of $7.9 million in the fourth quarter of 2012, an increase in net income of $12.0 million. The company ended 2013 with cash, cash equivalents and investments of $118.1 million, an increase of $9.5 million from the prior quarter.

"2013 was a year with significant achievements on many fronts - clinical, regulatory and commercial - which resulted in our successful launch of RAVICTI, the acquisition and effective integration of BUPHENYL into our commercial operation, and the advancement of another program expected to enter Phase 3 clinical testing in late 2014 or by early 2015," said Donald J. Santel, president and chief executive officer of Hyperion. "The commercialization of RAVICTI and BUPHENYL are going well and it is our privilege and pleasure to help the historically underserved urea cycle disorder community."

2013 Accomplishments

• Received FDA approval and launched RAVICTI, the first therapeutic alternative in 18 years for the chronic management of adult and pediatric patients with urea cycle disorders, or UCD, in patients two years and older.
• Received orphan drug exclusivity for RAVICTI offering protection against generic drug approval for the UCD indication until 2020.
• Obtained method of use patents that support claims in UCD until 2032.
• Acquired worldwide rights to BUPHENYL, enabling the company to offer another treatment option to the UCD patient community.
• Submitted to the FDA a package that outlined Hyperion's planned approach for measuring hepatic encephalopathy events in its planned pivotal clinical trial of glycerol phenylbutyrate.

Fourth Quarter 2013 Financial Results

Net income as measured under U.S. generally accepted accounting principles ("GAAP") was $0.5 million, or $0.02 per diluted share for the three months ended December 31, 2013 compared with a net loss of $8.3 million, or $(0.50) per diluted share for the same period of 2012. Adjusted net income was $4.1 million, or $0.19 per diluted share for the three months ended December 31, 2013 compared with an adjusted net loss of $7.9 million, or $(0.48) per diluted share for the same period in 2012. A reconciliation of adjusted net income (loss) to GAAP net income (loss) is provided in the accompanying table below entitled "Reconciliation of GAAP Net Income (Loss) to Adjusted Net Income (Loss)."

Revenue

During the three months ended December 31, 2013, Hyperion generated net product revenue of $18.6 million from the sale of RAVICTI and BUPHENYL. Net product revenue for the period consisted of $14.3 million in net sales from RAVICTI, a 46 percent increase from third quarter 2013 RAVICTI sales of $9.8 million, and $4.5 million in net sales from BUPHENYL partially offset by $0.2 million of co-payment assistance, a program to reduce financial burden for patients for both RAVICTI and BUPHENYL.

Cost of Sales

Cost of sales for the three months ended December 31, 2013 was $2.8 million and consisted of RAVICTI product costs of $1.5 million and BUPHENYL product costs of $1.3 million. Cost of sales related to the sales of RAVICTI is not representative of Hyperion's future expectations of this expense as manufacturing related expenses associated with RAVICTI sales were largely recorded to research and development expenses in periods prior to approval. As a result, cost of sales for RAVICTI for the next several quarters are expected to reflect a lower average per unit cost of materials as we sell product inventory that was previously expensed as research and development. Cost of sales related to the sales of BUPHENYL was higher and not indicative of future cost of sales due to the recording of the step-up value on BUPHENYL inventories which will be expensed to cost of sales as that inventory is sold.

Operating Expenses

Total adjusted operating expenses increased by $4.6 million to $12.0 million for the three months ended December 31, 2013 compared to $7.4 million for the three months ended December 31, 2012. On a GAAP basis, operating expense was $15.0 million for the fourth quarter 2013 compared to $7.8 million for the same period in 2012.

Research and Development (R&D)

Adjusted R&D expenses were $2.9 million for the three months ended December 31, 2013 and 2012. On a GAAP basis, R&D expense was $3.1 million for the fourth quarter of 2013 compared to $3.0 million for the same period in 2012.

Selling, General, and Administrative (SG&A)

Adjusted SG&A expenses increased by $4.6 million to $9.1 million for the three months ended December 31, 2013 compared to $4.5 million for the three months ended December 31, 2012. On a GAAP basis, SG&A expense was $10.1 million for the fourth quarter of 2013 compared to $4.8 million for the same period in 2012. The increase in GAAP expenses over the prior year period was primarily due to an increase in employee-related costs as a result of new hires, mainly in the commercial organization and other commercial and administrative related infrastructure expenses pertaining to the commercialization of RAVICTI and integration of BUPHENYL.

Amortization of Intangible Asset

Amortization of intangible asset was $1.7 million for the three months ended December 31, 2013 and pertains to the amortization expense for the BUPHENYL product rights acquired as part of the BUPHENYL acquisition on May 31, 2013.

Interest Expense

Interest expense decreased by $0.1 million to $0.4 million for the three months ended December 31, 2013, compared to $0.5 million for the three months ended December 31, 2012. This decrease was due to the decrease in the notes payable balance in 2013.

Cash, Cash Equivalents and Investments

As of December 31, 2013, Hyperion had cash, cash equivalents and investments of $118.1 million, an increase of $9.5 million from September 30, 2013.

2014 Expense Guidance

For 2014, Hyperion anticipates its adjusted operating expenses to be in the range of $52 million to $64 million which excludes amortization of the BUPHENYL intangible asset and stock-based compensation. The company expects amortization expense and stock-based compensation expense to be approximately $4 million to $5 million and $7.5 million to $8.5 million, respectively.
