Akebia Therapeutics Files Revised Definitive Proxy Statement for Special Stockholder Meeting

CAMBRIDGE, Mass. – March 24, 2023 – Akebia Therapeutics, Inc. (Nasdaq: AKBA), a biopharmaceutical company with the purpose to better the lives of people impacted by kidney disease, announced that it has filed a revised definitive proxy statement with the Securities and Exchange Commission (SEC) in connection with a special meeting (Special Meeting) of stockholders scheduled on April 11, 2023 at 10:00 a.m. ET in a virtual meeting format as a live webcast. Akebia is holding the Special Meeting to seek stockholder approval to, among other things, effect a reverse stock split of Akebia’s common stock, which Akebia believes would allow it to regain compliance with the Nasdaq Stock Market’s (Nasdaq) minimum bid price rule and avoid delisting.

The Special Meeting is being held to vote on several matters including amendments to Akebia’s charter to:

The revised proxy statement and proxy card replace the proxy statement and proxy card previously provided on or about March 1, 2023. The prior proxy card may not be used to vote at the Special Meeting and will be disregarded. The revised proxy materials were issued to submit Proposal 1(a) and Proposal 1(b) as separate items because different voting standards apply to each proposal.

NOTICE FOR STOCKHOLDERS: If you have already voted using the prior proxy card, you must vote again using the revised proxy card in order for your vote to be counted.

Akebia’s board of directors strongly recommends that stockholders vote “FOR” each of the proposals presented at the Special Meeting. Additionally, an “Update for Stockholders” presentation will be available via the Investors section of Akebia’s website at: https://ir.akebia.com.

If approved by stockholders and implemented by Akebia’s board of directors, a reverse stock split would be executed with the primary purpose to increase the price per share of Akebia’s common stock to, among other things, enable Akebia to comply with the Nasdaq continued listing requirements and avoid delisting. A vote to proportionally decrease the number of authorized shares in Proposal 1(b) would more appropriately align the number of authorized but unissued shares with Akebia’s needs and stockholder expectations.

“In May 2022 we reset our strategic focus around maximizing Auryxia revenue, supporting vadadustat and investing in our pipeline,” said John P. Butler, Chief Executive Officer of Akebia Therapeutics. “Our team has delivered on this promise, and we are also disputing the complete response letter that the FDA issued to our NDA for vadadustat. Despite this progress, we have not been able to increase the price per share of our common stock above one dollar for enough consecutive days to regain compliance with Nasdaq’s minimum bid price rule and must seek approval from stockholders to effect a reverse stock split. We continue to believe that maintaining a Nasdaq listing is critical to stockholder liquidity, maximizing value and, importantly, enabling our strategic vision. We will continue to work to progress towards potential milestones and will update shareholders appropriately with the goal of driving value and regaining compliance before the date required for a reverse split. However, we feel it is crucial to delivering shareholder value to secure the approval to effect a reverse stock split if necessary.”

In the event Akebia is delisted from Nasdaq, the only established trading market for its common stock would be eliminated, and Akebia would be forced to list its shares on the OTC Markets or another quotation medium, depending on its ability to meet the specific listing requirements of those quotation systems. As a result, an investor would likely find it more difficult to trade or obtain accurate price quotations for Akebia shares. Delisting would likely also reduce the visibility, liquidity, and value of Akebia’s common stock, reduce institutional investor interest in the company, and may increase the volatility of the common stock. Delisting could also cause a loss of confidence of potential industry partners, lenders, and employees, which could further harm Akebia’s business and future prospects.
