$14.7 million in net revenue for the third quarter 2021 (122% increase from second quarter 2021)

Steady increases in LUPKYNIS Patient Start Forms, Conversion Rates and Payer Coverage

Addition of two preclinical assets with potential in rare autoimmune conditions to grow and diversify the pipeline

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 third quarter ended September 30, 2021. Amounts, unless specified otherwise, are expressed in U.S. dollars.

Aurinia achieved third quarter revenue of $14.7 million, with nine months ended September 30, 2021 revenue of $22.2 million and maintains its previously stated annual revenue estimate in the range of $40 to $50 million for 2021.

“We are very pleased with Q3 results as we continue to execute on our LUPKYNIS commercialization strategies,” said Peter Greenleaf, President and Chief Executive Officer of Aurinia. “Despite the challenge of the COVID-19 Delta variant and a slight seasonal slowdown, we saw steady increases in patient start forms and patients on treatment toward the end of the quarter and continue to see this upward momentum through October.”

“Data presentations at key medical meetings this week, including additional interim results from the AURORA 2 continuation study, will help bolster awareness of and confidence in the efficacy and safety of LUPKYNIS and we expect final results of the continuation study to be announced by the end of 2021,” Greenleaf added.

“Finally, while our commercial team focused on increasing adoption of LUPKYNIS, Aurinia recently added two exciting preclinical assets – AUR200 and AUR300,” said Greenleaf. “We are eager to leverage our expertise and capabilities to advance these compounds for the treatment of rare autoimmune diseases with high unmet needs.”

Third Quarter 2021 Highlights & Upcoming Milestones:

• Aurinia has secured 412 patient start forms (PSFs) in the third quarter and as of November 3, 2021, Aurinia has secured a total of more than 1,265 PSFs.
• PSF conversion rates continue to increase with more than 68% of PSFs converted to patients on therapy. Q2 conversion rates were 50%. Time to convert continues to decrease since launch: 30- and 60-day conversion rates have improved each month.
• As of early October, Aurinia has confirmed coverage for LUPKYNIS through published payer policies for 65% of total lives in the market. Through patients gaining access to LUPKYNIS, the company now has confirmed coverage in plans covering 87% of total lives.
• On August 17, 2021, Aurinia announced the addition of two novel pipeline assets: AUR200, an Fc protein targeting BAFF/APRIL (B-cell Activating Factor, known as BAFF, and A Proliferation-Inducing Ligand known as APRIL) and AUR300, a novel peptide therapeutic that modulates M2 macrophages via the macrophage mannose receptor CD206. For the acquisitions, an Investigational New Drug Application (IND) filing for AUR200 is expected by the end of 2022 and an AUR300 IND filing is expected during the first half of 2023.
• On October 1, 2021, Aurinia’s licensing partner, Otsuka Pharmaceutical Co., Ltd., filed an initial marketing authorization application (MAA) with the Swiss Agency for Therapeutic Products (Swissmedic) seeking approval for the use of voclosporin for the treatment of adult patients with active LN. The Swiss filing was based on the June 24, 2021 MAA submission to the European Medicines Agency (EMA).
• Regulatory review of the EMA MAA remains on track with a Committee for Medicinal Products for Human Use (CHMP) opinion expected around mid-2022 followed by an EMA decision expected sometime in the third quarter of 2022. Additionally, Otsuka continues to work to finalize the timeline for the Japanese New Drug Application (JNDA) regulatory filing with Pharmaceutical and Medical Device Agency (PMDA) to seek approval of voclosporin for the treatment of LN in Japan.
• This week, Aurinia will present efficacy, safety and tolerability data for LUPKYNIS at two key medical meetings. The American College of Rheumatology (ACR) Convergence 2021 meeting (November 3-6) will feature an updated analysis of the AURORA 2 continuation study and two poster presentations on the efficacy of LUPKYNIS (from AURORA 1 data) across biopsy classes as well as in recent onset LN. The AURORA 2 updated interim analysis showed patients treated with LUPKYNIS maintained meaningful reductions in proteinuria with no change in mean eGFR at 30 months of treatment. At the American Society of Nephrology (ASN) Kidney Week 2021 (November 2-7) two Aurinia abstracts were accepted including an oral presentation on the efficacy of LUPKYNIS in achieving complete renal response in severe lupus nephritis.
• Data from the full AURORA 2 two-year continuation study is expected to be announced late in the fourth quarter of 2021.

Financial Liquidity at September 30, 2021

As of September 30, 2021, Aurinia had cash and cash equivalents and investments of $286.4 million compared to $422.7 million at December 31, 2020. The decrease was primarily related to the commercial infrastructure spend to support the launch of LUPKYNIS, payments for inventory, an upfront payment made as part of a collaborative agreement with Lonza to build a dedicated manufacturing capability (or monoplant) and an upfront license payment related to our recently acquired developmental program.

Net cash used in operating activities was $131.8 million for the nine months ended September 30, 2021 compared to $73.1 million for the nine months ended September 30, 2020. The increase was primarily due to the commercial infrastructure spend to support the launch of LUPKYNIS, payments for inventory and a one-time payment to a related party upon achievement of specific milestones partially offset by an increase in cash receipts. In the prior year, the Company was still in the development phase of LUPKYNIS.

The Company believes that it has sufficient financial resources to fund its current plans, which include funding commercial activities, including FDA related post approval commitments, manufacturing and packaging of commercial drug supply, funding our supporting commercial infrastructure, conducting planned research and development (R&D) programs, investing in our pipeline and operating activities into at least 2023.

Financial Results for the Quarter and Year Ended September 30, 2021

For the quarter ended September 30, 2021, Aurinia recorded a net loss of $50.3 million or $0.39 net loss per common share, as compared to a net loss of $42.1 million or $0.34 net loss per common share for the quarter ended September 30, 2020. For the nine months ended September 30, 2021, Aurinia recorded a net loss of $147.6 million or $1.15 net loss per common share as compared to a net loss of $94.6 million or $0.82 net loss per common share for the previous period.

Total revenue was $14.7 million and $29 thousand for the quarters ended September 30, 2021 and September 30, 2020, respectively. Total revenue was $22.2 million and $88 thousand for the nine months ended September 30, 2021 and September 30, 2020, respectively. Our revenues primarily consisted of product revenue, net of adjustments for LUPKYNIS, following FDA approval in January of 2021.

Cost of sales were $254 thousand and nil for the quarters ended September 30, 2021 and September 30, 2020, respectively. Cost of sales were $610 thousand and nil for the nine months ended September 30, 2021 and September 30, 2020, respectively. The increase for both periods was primarily the result of commercial sales of LUPKYNIS. Gross margin for the three and nine months ended September 30, 2021 was approximately 98% and 97% respectively.

Selling, general and administrative (SG&A) expenses were $44.1 million and $30.7 million for the quarters ended September 30, 2021 and September 30, 2020, respectively. For the nine months ended September 30, 2021 and September 30, 2020, SG&A expenses were $127.2 million and $57.2 million, respectively. The increase for both periods was due to the increase in salaries, incentive pay and employee benefits related to the expansion of the commercial and administrative functions to support the launch of LUPKYNIS which ramped up during the third quarter of 2020. Also contributing was an increase in professional fees for activities such as patient assistance programs, consulting, recruiting, legal, market research and marketing.

Non-cash SG&A share-based compensation expense for the three and nine months ended September 30, 2021 was $6.0 million and $19.2 million as compared to $3.8 million and $9.2 million for the same periods of 2020.

Research and Development (R&D) expenses were $20.1 million and $12.2 million for the quarters ended September 30, 2021 and September 30, 2020, respectively. For the nine months ended September 30, 2021 and September 30, 2020, R&D expenses were $40.0 million and $37.2 million, respectively. The primary driver for the increase for the three months ended September 30, 2021 as compared to the same period of 2020 was the upfront license and accrued milestone expense related to our recently acquired developmental programs, AUR200 and AUR300. In accordance with U.S. GAAP, these transactions did not meet the definition of a business combination and therefore, were recorded as asset acquisitions. We expensed the cost of the assets as R&D expense at the acquisition dates. The increase was partially offset by a decrease in clinical supply and distribution costs due to our new drug application and voclosporin related clinical trial expenditures in 2020 not recurring in 2021. Also contributing was a decrease in salaries, incentive pay and employee benefits due to the allocation of costs related to post approval support of LUPKYNIS to SG&A.

The primary drivers for the increase for the nine months ended September 30, 2021 as compared to the same period of 2020 were due to the upfront license and accrued milestone expense related to our recently acquired developmental programs, AUR200 and AUR300, and higher CRO expenses related to our new clinical programs offset by a decrease in clinical supply and distribution costs following the approval of LUPKYNIS, including a reduction in new drug application preparation costs and termination of the dry eye trial during the fourth quarter of 2020.

Non-cash R&D share-based compensation expense for the three and nine months ended September 30, 2021 was $1.0 million and $3.2 million as compared to $0.8 million and $3.1 million for the same periods of 2020.

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.
