Exhibit 99.1

CORIUM REPORTS SECOND FISCAL QUARTER 2014 FINANCIAL RESULTS

MENLO PARK, Calif., May 13, 2014 — Corium International, Inc. (NASDAQ: CORI), a commercial-stage biopharmaceutical company focused on the development, manufacture and commercialization of specialty transdermal products, today announced unaudited results from operations for both the second fiscal quarter and the six months ended March 31, 2014.

“Following the end of the second quarter, we completed our initial public offering, raising $48.5 million in net proceeds and significantly strengthening Corium’s financial position,” commented Peter Staple, Chief Executive Officer of Corium.  “We have taken a major step in advancing our business strategy, and we are now in a position to accelerate the development of several new clinical and preclinical stage proprietary products.  As we continue to apply our technology platforms to a range of new transdermal opportunities, we are particularly excited about developing our MicroCor products for the delivery of large molecules, which includes scaling up production to take our lead MicroCor candidate for osteoporosis into Phase 2 clinical trials in the coming year.”

Corium reported total revenues in the second fiscal quarter of 2014 of $10.7 million, compared with $12.5 million of total revenues in the second fiscal quarter of 2013.  The reduction in total revenues in the second fiscal quarter of 2014 primarily reflects the anticipated declines in full-year 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 of $1.0 million, primarily from new partner-funded development programs.

Total research and development (R&D) expenses in the second fiscal quarter of 2014 were $5.2 million, compared with $4.3 million of total R&D expense in the second fiscal quarter of 2013.  The increase in total R&D expense in the second fiscal quarter of 2014 primarily reflects the addition of new development programs with partners, as compared with the prior period, including two co-development programs.

Corium reported net income for the second fiscal quarter of 2014 of $3.5 million, or $0.33 per share on a fully-diluted basis, compared with a net loss of $2.0 million, or ($0.90) per share, in the second fiscal quarter of 2013.  As a result of Corium’s IPO on April 2, 2014, the fair value of an embedded derivative in a subordinated note was determined to be zero, resulting in a non-cash, non-recurring gain of $6.3 million in the second fiscal quarter of 2014.  Without the benefit of this gain, Corium would have recognized a non-GAAP net loss for the second fiscal quarter of 2014 of $2.8 million.

As of March 31, 2014, Corium had cash, cash equivalents and available-for-sale securities of approximately $5.3 million.  In its initial public offering completed in April 2014, Corium raised net proceeds of $48.5 million, after underwriting discounts and offering expenses, from the sale of approximately 6.9 million shares of its common stock at a price of $8.00 per share, including the exercise of the underwriters’ option to purchase additional shares.

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.
