AURINIA REPORTS FOURTH QUARTER AND FULL YEAR

2013 FINANCIAL RESULTS

Victoria, British Columbia – March 31, 2014: Aurinia Pharmaceuticals Inc. (TSX-V:AUP) (“Aurinia” or the “Company”) has released its financial results for the fourth quarter and year ended December 31, 2013.

Recent Developments

On February 14, 2014, Aurinia announced that it had completed a US$52 million (C$57.48 million) private placement (the “Offering”) pursuant to which the Company issued 18,919,404 units (the “Units”) at a subscription price per Unit of US$2.7485 (C$3.038), each Unit consisting of one common share and one-quarter (0.25) of a common share purchase warrant, exercisable for a period of five years from the date of issuance at an exercise price of US$3.2204 (C$3.56). All securities issued in connection with the Offering are subject to a four month hold period from the date of issuance in accordance with applicable securities law, which expires on June 15, 2014 for the securities issued at closing. The Offering was led by venBio, New Enterprise Associates (NEA), Redmile Group, RA Capital Management, Great Point Partners, and Apple Tree Partners, with participation from various other institutional investors, including existing shareholders Lumira Capital, ILJIN Life Science Co. Ltd. and Difference Capital.

In connection with the Offering, the Company also announced the appointment of Kurt von Emster, a founding partner of venBio, as a member of its Board of Directors.

Aurinia intends to use the net proceeds from the Offering primarily to advance the development of its lead drug candidate, voclosporin, as a therapy for lupus nephritis. Management believes that it now has the necessary resources in place to begin implementing its strategic plan for voclosporin, including the launch of a Phase 2b study of the drug in lupus nephritis in the second quarter of 2014.

Financial Results

For the fourth quarter ended December 31, 2013, the Company reported consolidated net income of $1.5 million or $0.12 per common share, as compared to a consolidated net loss of $5.2 million or $1.38 per common share for the same period in 2012.

For the year ended December 31, 2013, the Company recorded a net consolidated loss of $2.7 million or $0.43 per common share, as compared to a consolidated net loss of $9.7 million or $2.73 per common share in 2012.

Revenue increased to $746,000 for the fourth quarter of 2013, compared to $150,000 for the same period in 2012. This increase was due to recording the remaining deferred revenue balance of the 2006 Lux Biosciences, Inc. (“Lux”) upfront payment as licensing revenue in 2013.

The Company recorded revenue of $1.0 million for the year ended December 31, 2013, as compared to $6.1 million for the same period in 2012. In 2012 the Company recorded license revenue of $4.7 million which included the remaining $4.4 million of deferred revenue related to the 2011 initial upfront payment from ILJIN Life Science Co., Ltd. (“ILJIN”), and $1.3 million of other revenue on the completion of a sale agreement with Lux, for previously manufactured Active Pharmaceutical Ingredient.

Net research and development expenses decreased to $725,000 for the fourth quarter of 2013 compared to $3.3 million in the same period in 2012. Research and development expenses in the fourth quarter of 2013 were primarily related to preparatory stage activities, including drug capsule manufacturing for the planned Phase 2b lupus nephritis trial. Net research and development expenses were $2.1 million for the year ended December 31, 2013, compared to $5.5 million for the year ended December 31, 2012. The decrease reflected that the Company recorded a reserve of $2.7 million in the fourth quarter of 2012 for the drug supply manufactured in 2012 due to uncertainty in determining its net realizable value. The cost of the reserve was recorded in research and development expense as future use was determined to likely be for clinical trials for voclosporin.

Corporate and administration expenses were $944,000 for the fourth quarter of 2013, compared to $930,000 for the fourth quarter of 2012. The Company incurred corporate and administration expenditures of $2.4 million for the year ended December 31, 2013, as compared with $3.9 million for the year ended December 31, 2012. Corporate and administration expenses decreased in 2013 primarily as a result of significantly lower professional and consulting fees in 2013. The Company had incurred higher fees due to consulting services related to strategic alternatives and legal fees and arbitration costs related to the termination of the DDLA with ILJIN and the resulting arbitral process in 2012.

The Company incurred acquisition and restructuring costs of $30,000 for the fourth quarter of 2013 and $1.6 million for the year ended December 31, 2013 related to the acquisition of Aurinia Pharma Corp pursuant to the Plan of Arrangement on September 20, 2013 and subsequent restructuring of the Company. There were no similar costs in 2012.

Other expense reflected a net expense of $1.0 million for the fourth quarter ended December 31, 2013 compared to a net expense of $886,000 for the same period in 2012. Other expense was $955,000 for the year ended December 31, 2013 compared to a net expense of $5.6 million for the same period in 2012. Other expense in 2013 reflected fair value adjustments arising from the Plan of Arrangement completed on September 20, 2013 whereby the Company realized a gain on Aurinia Pharma Corp. of $3.7 million and a loss on contract settlement with ILJIN of $4.5 million. The 2012 expense included a non-cash loss of $4.2 million on the ILJIN derivative financial instrument and also included a provision for doubtful collection on the receivable of $1.3 million from Lux.

The Company recorded a non-cash deferred tax recovery of $4.1 million in the fourth quarter ended December 31, 2013. There was no similar item in 2012.

Many members of Aurinia’s current leadership team are former senior managers of Aspreva Pharmaceuticals (“Aspreva”), which Galenica acquired for C$915 million in 2008. While at Aspreva, this management team executed one of the largest and most important lupus nephritis studies ever conducted, called the Aspreva Lupus Management Study (“ALMS”), which resulted in the emergence of mycophenolate mofetil as a new standard treatment for patients suffering from this devastating and potentially fatal disease.
