QLT ANNOUNCES FOURTH QUARTER AND YEAR END 2013 RESULTS

VANCOUVER, CANADA — QLT Inc. (NASDAQ: QLTI; TSX: QLT) (“QLT” or the “Company”) is a biotechnology company dedicated to the development and commercialization of innovative ocular products that address the unmet medical needs of patients and clinicians worldwide. The Company reported financial results today for the fourth quarter and year ended December 31, 2013. Unless otherwise specified, all amounts are reported in U.S. dollars and in accordance with U.S. GAAP.

2013 FINANCIAL RESULTS

QLT Expenses / Other Income

Research and Development (R&D) expenses relate to QLT’s synthetic retinoid program. During the fourth quarter of 2013, QLT incurred R&D expense of $4.8 million, compared to $5.0 million for the same period in 2012. For the full year, R&D expense was $18.5 million compared to $24.6 million in 2012. The $6.1 million net decrease was primarily due to reduced staffing resulting from the Company’s 2012 restructuring initiatives.

During the fourth quarter of 2013, Selling, General and Administrative (SG&A) expense was $1.4 million compared to $2.4 million for the same period in 2012. For the full year, SG&A expense was $7.0 million compared to $15.1 million in 2012. For both periods, the decrease was primarily due to savings from the Company’s 2012 restructuring initiatives.

Investment and Other Income was $1.1 million and $3.3 million for the quarter and year ended December 31, 2013, respectively. For both periods, this primarily related to a gain of $1.0 million and $2.9 million, respectively, for the Fair Value Change in Contingent Consideration. This gain occurred primarily because our current contingent consideration asset is recorded as the present value of future expected payments with respect to Eligard^®, and therefore as each quarter elapses, even if no changes are made to the underlying Eligard forecast, we will book a gain related to the time value of money as we move one quarter closer to realizing the full face value of the assets.

Operating Losses

The operating loss for the fourth quarter was $6.6 million, compared to a $10.1 million operating loss recorded during the same period in 2012. The full year operating loss for 2013 was $28.5 million, compared to $54.7 million in 2012. The improvement in operating results of $3.5 million for the fourth quarter, and $26.2 million for the full year, in comparison to the same periods in 2012, are primarily due to savings related to the Company’s 2012 restructuring initiatives and restructuring charges recorded in 2012.

Income from Discontinued Operations, Net of Income Taxes

During the fourth quarter of 2013, we earned $0.9 million of income from discontinued operations, net of income taxes, compared to a $1.1 million loss incurred from discontinued operations in the fourth quarter of 2012. For the full year, we earned $1.0 million of income from discontinued operations, net of income taxes, compared to $88.0 million of income from discontinued operations in 2012. The decrease was primarily due to a pre-tax gain of $101.4 million related to the divestment of the Visudyne^® business recorded in the third quarter of 2012.

(Loss) / Income Per Share

Loss per share from continuing operations was $0.11 in the fourth quarter of 2013, compared to a loss per share from continuing operations of $0.16 in the fourth quarter of 2012. The improvement was primarily due to higher restructuring charges recorded in 2012 and savings related to the Company’s 2012 restructuring initiatives. These improvements were partially offset by a lower gain from the Fair Value Change in Contingent Consideration in the current period. For the full year, loss per share from continuing operations was $0.51 in 2013, compared to a loss per share of $0.84 in 2012. The improvement was due to the same factors described above as well as the 2012 income tax recovery resulting from the recognition of the tax benefit of our operating losses from continuing operations.

Income per share from discontinued operations was $0.02 for the fourth quarter of 2013, compared to a $0.02 loss per share from discontinued operations in the fourth quarter of 2012. For the full year, income per share from discontinued operations was $0.02, compared to $1.75 in 2012. The difference was primarily due to a pre-tax gain of $101.4 million related to the divestment of the Visudyne^® business recorded in the third quarter of 2012.

Cash and Cash Equivalents

As at December 31, 2013, the Company’s consolidated cash and cash equivalents was $118.5 million compared to $307.4 million of cash and cash equivalents at the end of 2012. The decrease was largely due to the $200.0 million special cash distribution to the Company’s shareholders completed in June 2013, which was partially offset by $7.5 million of funds that were released to us from escrow on September 26, 2013. During the fourth quarter of 2013, proceeds received in connection with collection of the Eligard Contingent Consideration totaled $10.5 million ($38.7 million collected in 2013). In addition, we still have up to $38.0 million of Eligard Contingent Consideration remaining to be collected.

Passive Foreign Investment Company

The Company believes that it was classified as a Passive Foreign Investment Company (PFIC) for 2008 – 2013, and that it may be classified as a PFIC in 2014, which could have adverse tax consequences for U.S. shareholders. Please refer to our Annual Report on Form 10-K for additional information.
