Corium Reports Fourth Quarter and Fiscal Year 2015 Financial Results and Year-End Highlights

MENLO PARK, Calif., November 12, 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 for the fourth quarter and fiscal year ended September 30, 2015 and reported on recent corporate developments.

Fourth Quarter and Fiscal Year 2015 Highlights

“We have had a year of tremendous achievement,  executing on our key clinical, corporate and financing objectives.  In our proprietary pipeline, we made significant strides in advancing three programs into the clinic.  With our MicroCor PTH product, we initiated and completed a Phase 2a study, reported positive results, and in doing so, provided strong clinical validation of Corium’s MicroCor transdermal platform.  We also initiated clinical development of our two Alzheimer’s disease product candidates, and are currently conducting Phase 1 trials of Corplex patches incorporating the two most widely used therapeutic agents,” said Peter D. Staple, Corium’s President and Chief Executive Officer.  “Strategically, we are committed to expanding our own product pipeline with a focus on CNS and to exploring first-in-patch applications that leverage our novel transdermal technologies.  As we enter 2016, we are well-positioned to advance our clinical-stage programs and to move new high-value transdermal therapeutics from concept through the clinic.”  

Financial Results for the Quarter Ended September 30, 2015

Corium reported total revenues in the fourth quarter of fiscal 2015 of $9.3 million, compared with $11.1 million in the fourth quarter of fiscal 2014.  The decrease in total revenues primarily resulted from declining product revenues from Fentanyl TDS (marketed by Par Pharmaceutical) and Clonidine TDS (marketed by Teva Pharmaceuticals), partially offset by growth in contract research and development revenues.  

Total research and development (R&D) expenses, including both proprietary and partnered programs, in the fourth quarter of fiscal 2015 were $8.6 million, compared with $7.8 million in the fourth quarter of fiscal 2014.  The increase in total R&D expenses primarily reflects Corium's increased investment in its proprietary product programs, including its development programs for Alzheimer's and Parkinson's diseases, as it advanced multiple formulation candidates through preclinical evaluation and two programs into Phase 1 clinical trials.

General and administrative (G&A) expenses in the fourth quarter of fiscal 2015 were $3.0 million, compared with $2.6 million in the fourth quarter of fiscal 2014.  The increase in G&A was primarily attributable to higher personnel and professional expenses.

Corium reported a net loss for the fourth quarter of fiscal 2015 of $8.6 million, or a loss of $0.42 per share on a fully-diluted basis, compared with a net loss of $6.4 million, or a loss of $0.35 per share, in the fourth quarter of fiscal 2014.  As of September 30, 2014 and September 30, 2015, there were 18,003,883 and 22,160,991 shares of Corium common stock outstanding, respectively.

Cash and cash equivalents as of September 30, 2015 were $72.2 million, reflecting the addition of capital from the Company’s follow-on equity financing in August. 

Financial Results for the Year Ended September 30, 2015

Corium reported total revenues for the year ended September 30, 2015 of $40.9 million.  This amount reflected a decline from revenues of $42.4 million for the year ended September 30, 2014,  primarily due to expected declines in product revenues from both Clonidine TDS (marketed by Teva Pharmaceuticals) and Fentanyl TDS (marketed by Par Pharmaceutical), partially offset by an increase in contract research and development revenues from co-development programs and new partner-funded programs.    In addition, revenues for the fiscal year ended September 30, 2014, included recognition of $1.8 million in non-cash product revenue that had been previously deferred since 2007.  The recognition of this revenue related to the expiration of a contractual liability, and does not have an impact on revenues after fiscal 2014.

Total research and development (R&D) expenses for 2015,  including both proprietary and partnered programs, were $32.5 million, compared with $22.8 million for 2014.  The increase primarily reflects the additional investment in 2015 for MicroCor technology and product programs, including the MicroCor PTH Phase 2a clinical trial, the first full year of investment in our Corplex CNS programs, along with new partner-funded development programs, and our co-development programs in which development costs are shared with the partner.

General and administrative (G&A) expenses for 2015 were $11.2 million, compared with $9.1 million for 2014.  The increase was primarily attributable to increased professional expenses, personnel costs and stock-based compensation expense associated with our first full year of operating as a public company.

Corium reported a net loss for 2015 of $28.5 million, or a loss of $1.52 per share on a fully-diluted basis, compared with a net loss of $9.9 million, or a loss of $0.99 per share, for 2014.   The 2014 net loss included a $7.4 million gain related to the valuation of a derivative liability that was recognized at the closing of the initial public offering.   Without the effect of the $7.4 million non-cash gain in 2014, Corium would have recognized a  non-GAAP net loss for 2014 of $17.3 million, or $1.72 per share.

Statement regarding use of non-GAAP financial measures 

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

Management believes the presentation of net loss and net loss per share that excludes the non-cash, non-recurring charge or 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 and net loss per share across reporting periods, especially as the number of shares outstanding were materially different across the same 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.
