ISS Joins Glass Lewis in Recommending Aurinia Shareholders Vote "FOR" ALL Company Director Nominees at 2023 Annual General Meeting

Aurinia Pharmaceuticals Inc. (NASDAQ: AUPH) ("Aurinia" or the "Company") today announced that leading independent proxy advisor Institutional Shareholder Services ("ISS") has recommended that Aurinia shareholders vote FOR the re-election of all eight incumbent directors to the Board of Directors (the "Board") at the Company's 2023 Annual General Meeting (the "Meeting").

ISS' positive recommendation follows an April 26 report from Glass Lewis, another leading independent proxy advisor, which also recommended that shareholders vote for the re-election of all incumbent directors.

Aurinia is pleased that ISS and Glass Lewis recognize the Board and management's pivotal role in the Company's continued growth and momentum. Aurinia's Board also appreciates the feedback and continued strong support of our shareholders.

Aurinia's Board and management are taking the right steps to maximize shareholder value.

Aurinia is well-positioned for significant value enhancement. The Company continues to build upon its robust sales growth ? with net sales increasing over 194% in 2022 ? and is making significant progress in expanding LUPKYNIS' availability in international markets in partnership with Otsuka.

In 2022, LUPKYNIS received approvals in the UK and EU and launched in several EU countries. Our efforts to gain regulatory approval in Japan remain on track, and we continue to expect a PMDA submission in the back half of 2023. We believe that our commercialization efforts will continue to unlock significant value for shareholders.

Each member of the Board has played an integral role in our progress to date. Our directors have the expertise needed to oversee and guide management and drive continued growth, including the commercialization of pharmaceutical and biotech products, business development, and international pharmaceutical operations. They also bring strong track records of value creation and commercial success.

Aurinia's executive compensation aligns pay with performance.

Aurinia disagrees with ISS' recommendation regarding the Company's advisory vote on executive compensation. 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. Aurinia has also engaged extensively with its shareholder base each year since the 2021 AGM and has made several improvements to the compensation program to incorporate feedback from shareholders, as detailed on page 54 of the proxy statement.

Importantly, ISS recognized that annual incentives for Aurinia executives were based largely on the achievement of pre-set corporate objectives, with the CEO's bonus being based solely on such goals. Aurinia has also previously announced that it will add a performance component to Long-Term Incentive Plan awards in 2023.

The Company also notes that leading proxy advisor Glass Lewis recommended shareholders vote "FOR" Aurinia's say-on-pay resolution, along with all other proposals. We will continue to listen to shareholder feedback regarding our executive compensation and other important matters.
