Aurinia has the right Board and management team to drive continued momentum and enhance shareholder value.

Our Board and management team have the right skills and expertise to continue to unlock value for all shareholders. Each director brings deep expertise in areas critical to the growth of our business, including the commercialization of pharmaceutical and biotech products, business development, and international pharmaceutical operations. Additionally, five of our eight directors bring R&D experience, six have clinical development expertise, and four have served in c-suite roles.

Aurinia's Board and management team remain focused on building upon the recent and growing momentum in the LUPKYNIS^® (voclosporin) business:

• Increased net sales more than 194% in 2022.
• Continued progress in key commercial areas of growth in patient start forms, faster conversion rates (time it takes to get a patient on therapy), improved adherence, and persistency (duration of therapy) rates in support of LN patients on therapy.
• Patients on therapy continue to grow quarter-on-quarter since launch.
• Recently issued a new method of use patent (U.S. Patent No. 11,622,991) for LUPKYNIS, adding intellectual property protection out to 2037 in the U.S.
• Achieved numerous milestones in the globalization of LUPKYNIS in partnership with Otsuka, including approvals in the UK and EU, launches in several EU countries and regulatory filings in Japan.

Our executive compensation aligns pay with performance to support continued value creation.

Our Compensation Committee, which is comprised entirely of independent directors, makes all compensation decisions while leveraging advice from an independent third-party compensation consultant. The Compensation Committee conducts a rigorous and thorough review of market practices, especially those of peers, the general marketplace and other industry data points to determine performance targets, pay mix and levels that will best align management's interests with those of shareholders and support continued value creation.

Over the past year Aurinia has extensively engaged with shareholders on executive compensation and other important matters. Based on these conversations, the Board made several changes to its executive compensation program, including:

• Introducing a share ownership policy for our directors and executive officers;
• Adopting a clawback policy for our executive officers; and
• Incorporating performance-based metrics into the annual equity grants for executives.
