Support Acorda’s Business Plan

Your Board of Directors, ISS and Glass Lewis, all recommend that you vote “FOR” the Reverse Stock Split (proposal 2). Approval of the Reverse Stock Split proposal is key to Acorda’s ability to execute its business plan.

Acorda issued a press release on October 27, 2022 on its long-term business plan and financial guidance through 2027, which we encourage you to review prior to your vote at the special meeting.

Acorda has developed a long-term business plan to increase the value of the Company, focused on growing INBRIJA^® (levodopa inhalation powder), maximizing AMPYRA^® (dalfampridine), and implementing additional operational and manufacturing efficiencies. Acorda has substantial liquidity which the Company expects will allow it to execute on this business plan.

Your vote is critically important. Please vote today. Vote FOR approval of the Reverse Split proposal to support execution of Acorda’s long-term business plan.
