Dear HIFsters,
I want to thank you once again for your dedication during these past months. Your focus and commitment since the announcement of our proposed merger with Keryx has positioned us well to capitalize on the significant growth opportunities that can result from this transaction.
If you are an Akebia shareholder, you have likely already received the proxy materials about the merger, including a letter from our Chairperson of the Board, Muneer Satter, explaining why the Akebia Board of Directors has unanimously recommended for shareholders to support the merger. I’m attaching Muneer’s letter, so that all employees can read his perspective, regardless of whether you own shares.
The deadline to vote on the merger-related shareholder proposals by internet or telephone is 11:59 p.m. Eastern on December 10, 2018 – which is fast approaching. I urge those of you who are shareholders to vote today“FOR” the shareholder proposals, set forth on the proxy card you received, by internet or telephone toll-free. Alternatively, you may also vote by signing, dating and returning the proxy card in the postage-paid envelope that was provided to you. If voting via mail, please ensure that you mail your proxy card so that it is received before December 11th, the Special Meeting date.Your vote is important, no matter how few or how many shares you own.

Together with Keryx, we will create a fully-integrated company focused on developing and delivering therapies to patients with kidney disease. I firmly believe this will enable us to positively impact people’s lives, and I could not be more excited about what lies ahead.
Thank you for your continued support of Akebia and our plans for the future.
Yours truly,
John P. Butler
