Exhibit 99.1

April 30, 2013
Dear Shareholders
On behalf of Unilife Corporation (“Unilife” or “Company”) (NASDAQ: UNIS; ASX: UNS), I am pleased to attach the Appendix 4C for the fiscal 2013 third quarter. An earnings call where management and I will discuss the fiscal 2013 third quarter results, and also provide an update on operational and commercial activities, has been scheduled to occur on Thursday, May 9, 2013, from 4.30 p.m. U.S. Eastern Daylight Time (Friday, May 10, 2013 from 6.30 a.m. Australian Eastern Standard Time).
At Unilife’s Fiscal 2012 Annual General Meeting of stockholders held in New York City on November 30, 2012, I had the opportunity to discuss our growth strategy and provide additional detail regarding the breadth and depth of our commercial pipeline. This included highlighting a selection of 30 active programs now underway with many of our current and prospective pharmaceutical customers, with a dozen expected to generate agreements and revenue during calendar year 2013.
Unilife recently announced the first of these agreements – a 15-year customization and commercial supply contract with a U.S. pharmaceutical company for our EZMix™ dual-chamber syringe. We expect this contract to generate up to $110 million in cumulative revenue from customization programs, production scale-up, device sales and a royalty from net drug sales.
This agreement validates many attractive aspects of our business model and highlights our capacity to generate revenue from multiple sources. With Unilife now finalizing discussions with multiple customers for other programs in our commercial pipeline, I expect the pace of news will soon begin to accelerate as we announce a succession of additional agreements featuring a combination of revenue streams including exclusivity fees, device customization programs and supply contracts.
Given the substantial size, complexity and long-term duration of many of these prospective agreements, each takes significant time to negotiate and finalize. However, I believe this wait will be more than justified as the agreements are announced and we transition into a new commercial phase of business with a diversified customer base that will drive strong, accelerating rates of growth and cash flow.
In recognition of the advanced status of some of these agreements, and our strong confidence in them being announced in the near to medium term, we are consciously managing our cash position to minimize dilution to existing shareholders.
I am therefore pleased to advise that we have agreed to preliminary terms with a leading U.S. life science financing firm for a debt funding program that we expect to finalize shortly. Combined with the anticipated revenue to be generated from new and existing customer agreements, we expect this medium-term debt program to strengthen our balance sheet, reduce the need for a secondary stock offering and thereby minimize potential dilution to existing shareholders.
We look forward to providing additional information regarding many of these exciting activities as news unfolds, and during our earnings call on Thursday, May 9th (Friday, May 10th in Australia).
Yours sincerely

Alan Shortall CEO
