Exhibit 99.1

Former Employee Issues Apology and

Withdraws Whistleblower Lawsuit

York, PA. – August 19, 2015 — Unilife Corporation (NASDAQ: UNIS and ASX: UNS), a developer, manufacturer and supplier of injectable drug delivery systems, today announced that a former employee has agreed to dismiss all of his claims against the Company and has issued a public apology for bringing his claims. The case, Talbot Smith v. Unilife Corp. et al, No. 13-CV-05101, filed in the United States District Court for the Eastern District of Pennsylvania, has been dismissed in its entirety with prejudice.

The former employee issued the following apology while dismissing the case: “I would like to correct issues arising from claims I brought against Unilife. I now understand that there were no violations of FDA regulations during my tenure at Unilife. In addition, in the summer of 2011, Unilife issued press releases which stated that they had begun shipments of validated Unifill product to customers. I now understand that the production process was in fact validated. Claims I brought were made in error and I apologize to Unilife, its shareholders, business partners and employees.”

John Ryan, Unilife’s Senior Vice President and General Counsel stated, “From the outset Unilife has asserted that Mr. Smith’s claims were entirely without merit and unfairly damaging to our Company and our shareholders. We are grateful to our attorneys, Carolyn Short and her colleagues at Reed Smith LLP, for their tireless work and this positive outcome. The Reed Smith team expertly uncovered the facts, showing Mr. Smith’s claims to be meritless, and we are of course pleased with this result. We are also pleased that in addition to apologizing to Unilife, Mr. Smith agreed to make a payment to the Company to settle our claims against him, that he received no payment as part of the resolution and dismissal, and that his attorney received only a small portion of her fees from our insurer. With this case now behind us, we look forward to focusing our resources fully on the growth of our business.”
