$21.6 million in net revenue for Q1 2022; Maintains net revenue guidance range of $115-$135 million from sales of LUPKYNIS for 2022

Continued increases in LUPKYNIS™ (voclosporin) Patients on Treatment and Patient Start Forms; Steady Conversion Rates and Payor Coverage

EMA review of LUPKYNIS remains on track with decision expected in 2H 2022

Conference call to be hosted today at 8:30 a.m. ET

Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH) (Aurinia or the Company) today issued its financial results for the first quarter ended March 31, 2022. Amounts, unless specified otherwise, are expressed in U.S. dollars.

Net product revenues were $21.6 million for the quarter ended March 31, 2022, compared to $914 thousand in the prior year period, reflecting FDA approval of LUPKYNIS in late January 2021.

“As previously reported on our fourth quarter call, LUPKYNIS revenues in the first quarter were impacted by care disruptions to both patients and the healthcare system caused by the COVID-19 Omicron variant. We are quite pleased that exiting the quarter, as Omicron abated, we began to see a significant increase in prescribing, patient starts, and refills, leading to a monthly record for received patient start forms and patient starts in March,” said Peter Greenleaf, President and Chief Executive Officer of Aurinia. “Heading into the second half of the year, in addition to expected growth in LUPKYNIS revenues, we look forward to multiple expected corporate milestones, including potential European LUPKYNIS approval, the presentation of additional clinical data sets and continued development progress with our pipeline products, AUR200 and AUR300.”

For fiscal year 2022, the Company maintains its net revenue guidance of $115 million to $135 million from sales of LUPKYNIS. This range is based on assumptions regarding the impact of COVID-19 on the current business environment and represents an increase of more than 150 to 200% in net revenue from sales of LUPKYNIS compared to fiscal year 2021. Aurinia’s guidance does not include any potential milestone payments, royalties or contract manufacturing revenue related to the Company’s licensing agreement with Otsuka Pharmaceutical or associated with the marketing of voclosporin in the European Union or Japan.

First Quarter 2022 and Recent Highlights & Upcoming Milestones:

• Aurinia added 461 patient start forms (PSFs) during the first quarter 2022, as compared to 257 in the first quarter 2021.
• As of Friday, May 6, 2022, the Company recorded 647 total PSFs since January 1, 2022.
• PSF conversion rates are now at 80% after 90 days; confirmed patient access to LUPKYNIS through payors and plans remains steady representing about 90% of U.S. total lives.
• There were approximately 1,071 patients on LUPKYNIS therapy at March 31, 2022, compared with 884 at the end of 2021. At 6 months post-treatment-start, an average of approximately 70% of patients remain on treatment.
• Per recent healthcare provider (HCP) surveys, unaided brand awareness of LUPKYNIS is over 70% while aided brand awareness is over 90% and intent to use in the next 3 months is over 70%, the highest level since launch.
• The first presentations of final AURORA 2 continuation study data are expected at the 59th European Renal Association (ERA) Congress and at the European Congress of Rheumatology at the end of May, 2022 and at the European Alliance of Associations for Rheumatology (EULAR) 2022 in June. Submission of a manuscript with the full results is expected in the second half of 2022.
• With the start of the year, the Aurinia commercial team initiated several new HCP and patient-targeted marketing programs that include the AURORA 2 data and patient brand ambassadors.
• Regulatory review of the European Medicines Agency (EMA) marketing authorization application (MAA) remains on track with a European Commission (EC) approval decision expected in second half of 2022.
• Recruitment of patients and initiation of new sites into both the VOCAL pediatric study and the ENLIGHT-LN registry is continuing.

Financial Liquidity at March 31, 2022

As of March 31, 2022, Aurinia had cash, cash equivalents and restricted cash and investments of $418.8 million compared to $466.1 million at December 31, 2021. The decrease in cash, cash equivalents and restricted cash and investments is primarily related to the continued investment in commercialization activities, payments made for our ongoing post approval obligations and advancement of our pipeline, payments associated with inventory purchases to ensure adequate supply to meet forecasted demand and a payment for the achievement of a one-time milestone, partially offset by an increase in cash receipts from sales of LUPKYNIS.

Aurinia believes that it has sufficient financial resources to fund its current operations, which include funding commercial activities, including FDA related post approval commitments, manufacturing and packaging of commercial drug supply, funding its supporting commercial infrastructure, conducting planned research and development (R&D) programs, investing in its pipeline and operating activities for at least the next few years.

Financial Results for the Quarter Ended March 31, 2022

Total net revenue was $21.6 million and $914 thousand for the quarters ended March 31, 2022 and March 31, 2021, respectively. Net revenues primarily consisted of product revenue, net of adjustments for LUPKYNIS, following FDA approval in late January 2021. Quarter over quarter revenue growth is attributed to continued progress in the launch of LUPKYNIS, driven predominantly by further penetration into the LN market.

Total cost of sales and operating expenses for the quarter ended March 31, 2022 were $59.5 million in comparison to $51.5 million for the quarter ended March 31, 2021.

Cost of sales were $256 thousand and $48 thousand for the quarters ended March 31, 2022 and March 31, 2021, respectively. The increase was primarily due to the growth of LUPKYNIS sales, in comparison to the prior year period.

Gross margin for the quarters ended March 31, 2022 and March 31, 2021 was approximately 99% and 95% respectively. The fluctuation in gross margin is driven primarily by fixed specialty pharmacy costs in the first quarter of 2021, as a larger percentage of the overall cost of sales in the quarter.

Selling, general and administrative (SG&A) expenses were $45.2 million and $39.8 million for the quarters ended March 31, 2022 and March 31, 2021, respectively, which is consistent with the prior quarter and represents a fully burdened quarter, as the Company did not have approval until late January 2021. The increase was primarily due to an increase in employee related expenses, professional fees related to various corporate matters, pharmacovigilance costs and consulting related expenses tied to the increased investment in back office infrastructure to support the commercialization of LUPKYNIS.

Non-cash SG&A share-based compensation expense for the quarters ended March 31, 2022 and March 31, 2021 was $6.0 million and $6.6 million, respectively.

R&D expenses were $12.6 million and $9.8 million for the quarters ended March 31, 2022 and March 31, 2021, respectively. The primary driver for the increase quarter over quarter was due to an increase in expenses related to AUR200 and AUR300 development, partially offset by a decrease in expenses related to the AURORA 2 continuation study which was completed during the fourth quarter of 2021 but had wind down activities ongoing in the quarter ended March 31, 2022.

Non-cash R&D share-based compensation expense for the quarters ended March 31, 2022 and March 31, 2021 was $1.0 million compared to $1.1 million, respectively.

For the quarter ended March 31, 2022, Aurinia recorded a net loss of $37.6 million or $0.27 net loss per common share, as compared to a net loss of $50.4 million or $0.40 net loss per common share for the quarter ended March 31, 2021.

About Lupus Nephritis

LN is a serious progression of systemic lupus erythematosus (SLE), a chronic and complex autoimmune disease. About 200,000-300,000 people live with SLE in the U.S. and approximately one out of three of these individuals have already developed LN at the time of SLE diagnosis. If poorly controlled, LN can lead to permanent and irreversible tissue damage within the kidney, resulting in kidney failure. Black and Asian individuals with SLE are four times more likely to develop LN and individuals with Hispanic ancestry are approximately twice as likely to develop the disease when compared with Caucasian individuals. Black and Hispanic individuals with SLE also tend to develop LN earlier and have poorer outcomes when compared to Caucasian individuals.
