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

Aurinia Pharmaceuticals Inc. (NASDAQ:AUPH) (Aurinia or the Company) today provided an update on its 2023 fourth quarter and full year business performance, as well as a corporate update regarding the Company's strategic review. This includes corporate actions designed to enhance shareholder value, including an exclusive focus on driving commercial execution of the LUPKYNIS^® (voclosporin) business, and a significant share repurchase program.

Effective immediately, Aurinia will discontinue its future development of AUR200 and AUR300 research and development programs and prioritize resource allocation. This will result in a one-time charge in the first quarter of 2024 of approximately $11 - $15 million and expected operational cost savings of approximately $50 - $55 million annually, with approximately 75% of the savings being recognized in 2024 excluding the one-time restructuring charge in the first quarter of 2024.

Aurinia's Board of Directors (the "Board") also approved a share repurchase program of up to $150 million common shares of the Company (each, a "Common Share"), affirming its confidence in the Company's growth prospects. The maximum amount of the share repurchase program is subject to receipt of regulatory approval in Canada.

"Our strong performance and growth for LUPKYNIS throughout 2023 demonstrates the ongoing success of our commercial strategy. We will continue to focus on driving the upward trajectory of LUPKYNIS, while significantly reducing expenses and providing increased cash flow for 2024 and beyond. With our deeply experienced and dedicated team, we have built a strong foundation for Aurinia's growth that will lead us into another high performing year. We are confident in the actions we have taken to drive increased shareholder value and will continue to act with urgency for the benefit of shareholders," said Peter Greenleaf, President and CEO of Aurinia.

Aurinia Corporate Strategy Update

The Board initiated a robust strategic review at the end of June 2023 to review all strategic options for the Company. Together with management, JP Morgan, the Company's financial advisor in the strategic review process, engaged with more than 60 parties, receiving only one non-binding expression of interest, which included a due diligence process, but did not result in a formal offer.

Aurinia also explored potentially acquiring or licensing other entities or assets during this time. After assessing a range of alternatives over the last seven months, the Board elected to conclude Aurinia's strategic review process. The Board ultimately determined that none of the explored opportunities that were available to it to pursue were in the best near-term interests of the Company to execute on, and that the best path forward is for management to streamline its operations as it announced today and focus on the Company's commercial execution.

Additionally, in 2018, the Company under previous management and at the Board's discretion, engaged a leading investment bank to conduct a confidential strategic review process. During the 2018 process, the Company received only one non-binding expression of interest to acquire the Company, which included a due diligence process, but did not result in a formal offer.

Outside of these two expressions of interest, the Company has never received an offer of any kind to acquire the Company. The Board and management remain open to exploring opportunities that are in the best interests of the Company and are open to considering any bona fide offers that the Company receives.

"The Board and management conducted a wide-ranging review of strategic alternatives for our business and determined that the ongoing commercial transformation provides the best means for enhancing near-term value for shareholders and other stakeholders. As the most recent performance update indicates, Aurinia is financially strong and is continuing to achieve commercial success with LUPKYNIS. With a clear plan to strengthen short and long-term performance and generate free cash flow by the end of this year, the Board is fully confident the Company's current approach is in the best interests of the Company," said Dr. Daniel Billen, Chairman of the Board of Aurinia.

The Company is reaffirming its commitment to enhancing value by driving LUPKYNIS growth, while maintaining a sharp focus on operating efficiencies and maximizing cash flows. As a result, the Company is ceasing future development efforts on AUR200 and its pre-clinical asset AUR300. Correspondingly, the Company expects to take a restructuring charge of approximately $11 - $15 million in the first quarter of 2024. The Company anticipates reducing employee headcount by at least 25% by the end of the first quarter of 2024. There is no planned reduction in headcount in commercial or commercial supporting roles.

The charge will primarily be made up of severance costs, contract termination costs and other costs associated with terminating the programs. The Company expects to recognize cost savings of approximately $50 - $55 million annually, with approximately 75% of the savings being recognized in 2024 excluding the one-time restructuring charge in the first quarter of 2024, with no impact on commercial investment.

In addition, the Board has approved a share repurchase program of up to $150 million of Common Shares, reflecting confidence in Aurinia's growth prospects. Aurinia has submitted an exemptive relief application to applicable Canadian securities regulators which, if granted, would permit Aurinia to purchase up to 15% of the issued and outstanding Common Shares of the Company in any 12-month period for 36 months (the "Exemptive Relief"). There is no assurance the Exemptive Relief will be granted on the terms applied for or at all. If the Exemptive Relief is not granted, the maximum the Company may purchase under this share repurchase program in reliance on the normal course issuer bid exemption under applicable Canadian securities regulation is 5% of its current issued and outstanding Common Shares (being 7,230,888 Common Shares).

Purchases under the share repurchase program will commence on or around February 21, 2024. The expiry date of the share repurchase program is not currently known. This program may be implemented through open market or privately negotiated purchases, including under a plan intended to benefit from the affirmative defense under Rule 10b5-1, Rule 10b-18 or an automatic securities purchase plan, an accelerated share repurchase program, or other mechanisms. The timing and amount of repurchase transactions will be determined by the Company's management based on its evaluation of market conditions, share price, legal requirements, including applicable blackout period restrictions, and other factors. The purchase price of any Common Shares will be determined in accordance with applicable U.S. securities laws and subject to receiving the Exemptive Relief, the value of the consideration offered per Common Share will not exceed the market price of the Common Shares calculated pursuant to applicable Canadian securities regulation.

"We have a very healthy balance sheet that enables a disciplined capital deployment policy to support Aurinia's growth, while also increasing returns to shareholders," said Joe Miller, Chief Financial Officer of Aurinia.

Financial Results for the Quarter and Year Ended December 31, 2023

Total net revenue was $45.1 million and $28.4 million for the quarters ended December 31, 2023 and December 31, 2022, respectively. Total net revenue was $175.5 million and $134.0 million for the years ended December 31, 2023 and December 31, 2022, respectively. Product Revenue, net was $42.3 million and $28.3 million for the quarters ended December 31, 2023 and 2022, respectively. Product Revenue, net was $158.5 million and $103.5 million for the years ended December 31, 2023 and 2022, respectively. The Company currently has two main customers for U.S. commercial sales of LUPKYNIS and a collaboration partnership with Otsuka for sales of semi-finished product and license, collaboration and royalty revenue in Otsuka Territories. The increase in both periods is primarily due to an increase in LUPKYNIS sales to our two main customers, driven predominantly by further penetration of the LN market.

The market penetration can be demonstrated, in part, by 1,791 additional patient start forms (PSFs) received during the year ended December 31, 2023. Additionally, during the fourth quarter of 2023, the Company added approximately 101 new patients, which includes, restarts (patients coming back onto therapy who do not require a PSF) and an estimate of new patients beginning therapy in the hospital channel. Patient restarts and estimated patients coming through the hospital channel are newly reported in the fourth quarter since they have achieved numerical significance for the first time. Lastly, the Company's 12-month persistency rate has increased from approximately 50% at December 31, 2022 to approximately 55% at December 31, 2023. These factors have contributed to an increase in patients on therapy with approximately 2,066 patients on LUPKYNIS therapy at December 31, 2023, compared with 1,525 at December 31, 2022.

License, collaboration and royalty revenue was $2.8 million and $0.1 million for the quarters ended December 31, 2023 and 2022, respectively. License, collaboration and royalty revenue was $17.0 million and $30.6 million for the years ended December 31, 2023 and 2022, respectively. For the year ended December 31, 2023, license, collaboration and royalty revenue included a $10.0 million pricing and reimbursement milestone in September 2023 and additional collaboration and manufacturing services revenue from Otsuka. For the year ended December 31, 2022, license, collaboration and royalty revenue was primarily due to the recognition of a $30.0 million regulatory milestone from Otsuka following the EC marketing authorization of LUPKYNIS in September 2022.

Total cost of sales and operating expenses for the quarters ended December 31, 2023 and December 31, 2022 were $74.8 million and $56.5 million, respectively. Total cost of sales and operating expenses were $267.2 million and $245.5 million for the years ended December 31, 2023 and December 31, 2022, respectively. Further breakdown of operating expenses drivers and fluctuations are highlighted in the following paragraphs.

Cost of sales were $5.4 million and $1.4 million for the quarters ended December 31, 2023 and December 31, 2022, respectively. Cost of sales were $14.1 million and $5.7 million for the years ended December 31, 2023 and December 31, 2022, respectively. The increase in both periods was primarily due to an increase in sales of LUPKYNIS, coupled with the amortization of the monoplant finance lease right-of-use asset, which was placed into service in late June 2023.

Gross margin for the quarters ended December 31, 2023 and December 31, 2022 was approximately 88% and 95% respectively. Gross margin for the years ended December 31, 2023 and December 31, 2022 was approximately 92% and 96%, respectively.

Selling, general and administrative (SG&A) expenses, inclusive of share-based compensation expense, were $50.1 million and $47.5 million for the quarters ended December 31, 2023 and December 31, 2022, respectively. The increase in total SG&A expense was primarily due to an increase in share-based compensation expense. SG&A expenses, inclusive of share-based compensation expense, were $195.0 million and $196.4 million for the years ended December 31, 2023 and December 31, 2022, respectively. The decrease was primarily due to a reduction in expenses associated with corporate legal matters and insurance.

Non-cash SG&A share-based compensation expense were $9.5 million and $7.0 million for the quarters ended December 31, 2023 and December 31, 2022, respectively. Non-cash SG&A share-based compensation expense was $36.5 million and $28.4 million for the years ended December 31, 2023 and December 31, 2022, respectively.

Research and Development (R&D) expenses, inclusive of share-based compensation expense, were $10.2 million and $9.9 million for the quarters ended December 31, 2023 and December 31, 2022, respectively. R&D expenses, inclusive of share-based compensation expense, were $49.6 million and $45.0 million for the years ended December 31, 2023 and December 31, 2022, respectively. The primary driver for the increase in R&D expenses for both periods was due to the increase in share-based compensation expense.

Non-cash R&D share-based compensation expense and income was $1.9 million and $(0.3) million for quarters ended December 31, 2023 and December 31, 2022, respectively. Non-cash R&D share-based compensation expense was $7.5 million and $3.3 million for the years ended December 31, 2023 and December 31, 2022, respectively.

Other expense (income), net was $9.1 million and $(2.2) million for the quarters ended December 31, 2023 and December 31, 2022, respectively. Other expense (income), net was $8.4 million and $(1.5) million for the years ended December 31, 2023 and December 31, 2022, respectively. The increase in expense for both periods is primarily due to an increase in the foreign exchange loss related to the revaluation of the monoplant finance lease liability, which commenced in June 2023 and is denominated in CHF.

Interest income was $4.6 million and $2.9 million for the quarters ended December 31, 2023 and December 31, 2022, respectively. Interest income was $17.0 million and $5.1 million for the years ended December 31, 2023 and December 31, 2022, respectively. The increase for the quarter and full year was mainly due to higher yields on our investments as a result of increasing interest rates.

For the quarter ended December 31, 2023, Aurinia recorded a net loss of $26.9 million or $0.19 net loss per common share, as compared to a net loss of $26.0 million or $0.18 net loss per common share for the quarter ended December 31, 2022. For the year ended December 31, 2023, Aurinia recorded a net loss of $78.0 million or $0.54 net loss per common share as compared to a net loss of $108.2 million or $0.76 net loss per common share for the previous period.

Financial Liquidity at December 31, 2023

As of December 31, 2023, Aurinia had cash, cash equivalents and restricted cash and investments of $350.7 million, compared to $389.4 million at December 31, 2022. The decrease is primarily related to the continued investment in commercialization activities and post approval commitments of our approved drug, LUPKYNIS, inventory purchases, advancement of Aurinia's pipeline and monoplant payments, partially offset by an increase in cash receipts from sales of LUPKYNIS.

Aurinia believes that it has sufficient financial resources to fund its operations, which include funding commercial activities, including FDA related post approval commitments, manufacturing and packaging commercial drug supply, funding its commercial infrastructure, advancing its LUPKYNIS (voclosporin) related R&D programs and funding its working capital obligations for at least the next few years.

This press release is intended to be read in conjunction with the Company's consolidated financial statements and Management's Discussion and Analysis for the year ended December 31, 2023 in the Company's Annual Report on Form 10-K, which will be accessible on Aurinia's website at www.auriniapharma.com, on SEDAR+ at www.sedarplus.ca or on EDGAR at www.sec.gov/edgar.

About LUPKYNIS^®

LUPKYNIS^® (voclosporin) is the first U.S. Food and Drug Administration and European Commission approved oral medicine for the treatment of adult patients with active lupus nephritis (LN). LUPKYNIS^® is a second generation calcineurin inhibitor (CNI) with a dual mechanism of action, acting as an immunosuppressant through inhibition of T-cell activation and cytokine production and promoting podocyte stability in the kidney. The AURORA Clinical Program, comprised of the AURORA 1 pivotal trial and AURORA 2 extension trial, demonstrated the importance of LUPKYNIS^® plus standard of care to preserve kidney health in patients with active LN without reliance on chronic high-dose glucocorticoids. It is the only clinical program to include three years of LN treatment and follow-up with mycophenolate mofetil (MMF) and steroids.

About Lupus Nephritis

Lupus Nephritis (LN) is a serious manifestation of systemic lupus erythematosus (SLE), a chronic and complex autoimmune disease. LN affects approximately 120,000 people in the U.S. and disproportionately affects women and people of color. People living with LN have high unmet needs and often face significant barriers to optimal care. If poorly controlled, LN can lead to permanent and irreversible tissue damage within the kidney. Medical guidelines recommend that all SLE patients receive routine LN screenings at every visit. Guidelines also note that delaying LN diagnosis has profound prognostic repercussions. Yet, research shows that approximately 50% of SLE patients are not screened for LN and 77% of people with LN go untreated. Aurinia is committed to improving health outcomes for people living with LN by educating patients and providers on the critical need for routine screening and transformative therapies that can help improve health outcomes.

About Aurinia

Aurinia Pharmaceuticals is a fully integrated biopharmaceutical company focused on delivering therapies to people living with autoimmune diseases with high unmet medical needs. In January 2021, the Company introduced LUPKYNIS^® (voclosporin), the first FDA-approved oral therapy dedicated to the treatment of adult patients with active lupus nephritis. The Company's head office is in Edmonton, Alberta, its U.S. commercial office is in Rockville, Maryland. The Company focuses its development efforts globally.
