CORIUM  REPORTS THIRD  QUARTER  FISCAL 2015 FINANCIAL RESULTS 

Conference Call and Webcast to Highlight Third Quarter Fiscal 2015 and Topline Results from MicroCor® PTH Phase 2a Clinical Trial

MENLO PARK, Calif.,  July 29, 2015 — Corium International, Inc. (Nasdaq: CORI), a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty transdermal products, today announced unaudited financial results from operations for both the third fiscal quarter and the nine months ended June 30, 2015.  Corium’s fiscal year ends on September 30.    

Recent Corporate Developments

“We are currently advancing four high-value product candidates into and through clinical development based on our MicroCor and Corplex technology platforms.  These products, which include small and large molecule therapeutics, all have the potential to address significant clinical needs,” said Peter D. Staple, President and Chief Executive Officer of Corium.  “The positive outcome of our MicroCor PTH Phase 2a clinical study provides a strong foundation for advancing this promising new treatment for osteoporosis into late-stage clinical development.  The study also reinforces the robustness and reproducibility of the MicroCor platform for the rapid delivery of large molecules.    In parallel, we  are advancing our three CNS product development program candidates, starting with our Donepezil TDS Phase 1 trial this summer.”    

Financial Results for the Quarter Ended June 30, 2015

Corium reported total revenues in the third quarter of fiscal 2015 of $10.6 million, compared with $10.2 million in the third quarter of fiscal 2014.  The increase in total revenues primarily resulted from growth in contract research and development revenues, as well as recognition of a new consumer product launch milestone, partially offset by the continued declines in product revenues from Fentanyl TDS (marketed by Par Pharmaceutical) and Clonidine TDS (marketed by Teva Pharmaceuticals).  

Total research and development (R&D) expenses in the third quarter of fiscal 2015 were $7.6 million, compared with $5.4 million in the third quarter of fiscal 2014.  The increase in total R&D expenses primarily reflects Corium’s increased investment in its proprietary product programs, including the advancement of Corium’s MicroCor PTH program into Phase 2a clinical trials that began in February 2015, as well as increased investment in its product development programs for Alzheimer’s and Parkinson’s diseases as it advanced multiple formulation candidates through preclinical evaluation.

General and administrative (G&A) expenses in the third quarter of fiscal 2015 were $2.8 million, compared with $3.5 million in the third quarter of fiscal 2014.  The decrease in G&A was primarily attributable to higher bonus expense incurred in the quarter ended June 30, 2014 following Corium’s Initial Public Offering (IPO) in April 2014.

Corium reported a net loss for the third quarter of fiscal 2015 of $5.9 million, or $0.33 per share, compared with a  net loss of $5.0 million, or $0.28 per share, in the third quarter of fiscal 2014.  As of June 30, 2015, there were 18,158,559 shares of Corium common stock outstanding.

Cash and cash equivalents as of June 30, 2015 were $29.5 million.    

Financial Results for the Nine Months Ended June 30, 2015

Corium reported total revenues for the nine months ended June 30,  2015 of $31.7 million, compared with $31.4 million for the same period in 2014.  The increase in total revenues primarily reflects an increase in contract research and development revenues from co-development and partner funded programs, partially offset by expected declines in product revenues from Fentanyl TDS and Clonidine TDS. 

Total R&D expenses for the nine months ended June 30, 2015 were $24.0 million, compared with $15.0 million for the same period in 2014.  The increase in total R&D expenses primarily reflects Corium’s increased investment in its proprietary product programs, including the advancement of Corium’s MicroCor PTH program into Phase 2a clinical trials that began in February 2015 and its product development programs for Alzheimer’s and Parkinson’s diseases.

G&A expenses for the nine months ended June 30, 2015 were $8.2 million, compared with $6.5 million for the same period in 2014.  The increase in G&A was primarily attributable to higher expenses associated with becoming a public company, including the expense associated with the award of stock options to employees and directors following Corium’s IPO.

Corium reported a net loss for the nine months ended June 30, 2015 of $19.8 million, or $1.10 per share, compared with a  net loss of $3.5 million, or $0.48 per share, for the same period of 2014.  As a result of Corium’s progress towards an IPO during the nine months ended June 30, 2014, the fair value of an embedded derivative in a subordinated note was reduced in both the first and second fiscal quarters of 2014, resulting in non-cash, non-recurring gains totaling  $7.4 million in the first nine months of fiscal 2014.  Without the benefit of this gain, Corium would have recognized a non-GAAP net loss of $10.9 million for the nine months ended June 30, 2014.

Statement regarding use of non-GAAP financial measures

The company reported non-GAAP net loss in this release in addition to, and not as a substitute for, or superior to, net loss calculated in accordance with GAAP.

Management believes the presentation of net loss that excludes the non-cash, non-recurring gain from the change in fair value of an embedded derivative provides useful supplemental information to investors and facilitates the analysis of the company’s core operating results and comparison of net loss across reporting periods.  Management also believes that this supplemental non-GAAP information is therefore useful to investors in analyzing and assessing the company’s past and future operating performance.

The company encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business.
