FOR IMMEDIATE RELEASE

Unilife Corporation Announces Financial Results

For Fiscal Year 2012 Second Quarter

York, PA (February 9, 2012) Unilife Corporation (“Unilife” or “Company”) (NASDAQ: UNIS; ASX: UNS) today announced financial results for the quarter ended December 31, 2011 (Second Quarter of Fiscal Year 2012).

Recent Highlights:

“Unilife has made excellent progress across all areas of its business during the quarter ended December 31, 2011. As we enter calendar year 2012, I believe that we have the broad operational capabilities and high-performance team in place to achieve a series of previously announced key business milestones,” stated Mr. Shortall.

“In this regard, I recently made the decision to further increase my position as Unilife’s largest shareholder with the purchase of approximately $1.0 million of common stock in the open market. This decision further underlines my confidence in the strength of Unilife’s current business position. I plan to continue purchasing Unilife common stock in the open market moving forward, in line with our trading policies and SEC regulations.

“In November 2011, we completed a capital raise that bolstered our cash position in order to help support the negotiation of favorable agreements with pharmaceutical customers, the continued expansion of our portfolio of proprietary devices, and to further increase our operational capabilities. An additional benefit of the capital raise is that through the placement of shares with primarily blue chip, healthcare dedicated and long-only funds, we have an expanded investor base and created greater liquidity for the Company’s common stock,” concluded Mr. Shortall.

Financial Results for Three Months Ended December 31, 2011

Revenues for the three months ended December 31, 2011 were $0.9 million compared to $1.8 million for the same period in 2010. The variation in revenue reflects the Company’s strategic decision to discontinue its contract manufacturing operation in December 2010 and instead, focus on the commercialization, production and supply of its own propriety line of products. In addition, during the three months ended December 31, 2011 the Company recognized revenue of $0.2 million related to the clinical development and supply of a novel device for targeted organ delivery.

The Company’s net loss for the three months ended December 31, 2011 was $12.9 million, or $0.19 per diluted share, compared to a net loss of $10.4 million, or $0.19 per diluted share, for the same period in 2010. The increase in the net loss was primarily attributable to an increase in research and development expenses related to the development of additional advanced drug delivery devices. These amounts were partially offset by a reduction of $1.3 million in selling, general and administrative expenses.

Adjusted net loss for the three months ended December 31, 2011 was $9.6 million, or $0.14 per diluted share, compared to $7.6 million, or $0.14 per diluted share, for the same period in 2010. Adjusted net loss excludes non-cash share-based compensation expense, depreciation and amortization and interest expense.

As of December 31, 2011, the Company’s cash, cash equivalents and restricted cash were $41.7 million.

Forward-Looking Statements

This press release contains forward-looking statements. All statements that address operating performance, events or developments that we expect or anticipate will occur in the future are forward-looking statements. These forward-looking statements are based on management’s beliefs and assumptions and on information currently available to our management. Our management believes that these forward-looking statements are reasonable as and when made. However, you should not place undue reliance on any such forward-looking statements because such statements speak only as of the date when made. We do not undertake any obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. In addition, forward-looking statements are subject to certain risks and uncertainties that could cause actual results, events and developments to differ materially from our historical experience and our present expectations or projections. These risks and uncertainties include, but are not limited to, those described in “Item 1A. Risk Factors” and elsewhere in our Annual Report on Form 10-K and those described from time to time in other reports which we file with the Securities and Exchange Commission.

Non-GAAP Financial Measures

U.S. securities laws require that when we publish any non-GAAP financial measure, we disclose the reason for using the non-GAAP measure and provide a reconciliation to the most directly comparable GAAP measure. The presentation of adjusted net income (loss) and adjusted net income (loss) per share are non-GAAP measures. Adjusted net income (loss) represents net income (loss) calculated in accordance with U.S. GAAP as adjusted for the impact of share-based compensation expense, depreciation and amortization and interest expense.

Management believes the presentation of adjusted net income (loss) and adjusted net income (loss) per share provides useful information because these measures enhance its own evaluation, as well as investor’s understanding, of the Company’s core operating and financial results. Non-GAAP financial measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. A reconciliation of net income (loss) to adjusted net income (loss) is included in the attached table.
