FOR IMMEDIATE RELEASE

Acorda Provides Financial and Pipeline Update for Third Quarter 2017

ARDSLEY, NY – October 31, 2017 – Acorda Therapeutics, Inc. (Nasdaq: ACOR) provided a financial and pipeline update for the third quarter ended September 30, 2017.

“We have had a constructive dialogue with the FDA since the issuance of its Refusal to File letter, and we plan to resubmit the INBRIJA NDA in the fourth quarter. We believe our resubmission reflects a strong package that incorporates feedback we received from FDA,” said Ron Cohen, M.D., Acorda's President and CEO. “We are also on track to announce top-line data from our Phase 3 study of tozadenant in the first quarter of 2018.”

“INBRIJA and tozadenant are being developed as therapies for people with Parkinson’s, INBRIJA for on-demand use to treat symptoms of OFF periods and tozadenant as a daily oral treatment to increase overall ON time. If approved, they have the potential to position Acorda as a leader in the development of Parkinson’s therapy, creating substantial value for shareholders.”

Forward-Looking Statement

This press release includes forward-looking statements. All statements, other than statements of historical facts, regarding management's expectations, beliefs, goals, plans or prospects should be considered forward-looking. These statements are subject to risks and uncertainties that could cause actual results to differ materially, including: the ability to realize the benefits anticipated from the Biotie and Civitas transactions, among other reasons because acquired development programs are generally subject to all the risks inherent in the drug development process and our knowledge of the risks specifically relevant to acquired programs generally improves over time; the ability to successfully integrate Biotie’s operations into our operations; we may need to raise additional funds to finance our operations and may not be able to do so on acceptable terms; our ability to successfully market and sell Ampyra (dalfampridine) Extended Release Tablets, 10 mg in the U.S., which will likely be materially adversely affected by the March 2017 court decision in our litigation against filers of Abbreviated New Drug Applications to market generic versions of Ampyra in the U.S.; the risk of unfavorable results from future studies of Inbrija (CVT-301, levodopa inhalation powder), tozadenant or from our other research and development programs, or any other acquired or in-licensed programs; we may not be able to complete development of, obtain regulatory approval for, or successfully market Inbrija, tozadenant, or any other products under development; third party payers (including governmental agencies) may not reimburse for the use of Ampyra, Inbrija or our other products at acceptable rates or at all and may impose restrictive prior authorization requirements that limit or block prescriptions; the occurrence of adverse safety events with our products; failure to maintain regulatory approval of or to successfully market Fampyra outside of the U.S. and our dependence on our collaborator Biogen in connection therewith; competition; failure to protect our intellectual property, to defend against the intellectual property claims of others or to obtain third party intellectual property licenses needed for the commercialization of our products; and failure to comply with regulatory requirements could result in adverse action by regulatory agencies.

These and other risks are described in greater detail in our filings with the Securities and Exchange Commission. We may not actually achieve the goals or plans described in our forward-looking statements, and investors should not place undue reliance on these statements. Forward-looking statements made in this press release are made only as of the date hereof, and we disclaim any intent or obligation to update any forward-looking statements as a result of developments occurring after the date of this press release.

Non-GAAP Financial Measures

This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and also certain historical and forward-looking non-GAAP financial measures. In particular, Acorda has provided non-GAAP net income, adjusted to exclude the items below, and has provided 2017 guidance for R&D and SG&A on a non-GAAP basis. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, the Company believes the presentation of non-GAAP net income, when viewed in conjunction with our GAAP results, provides investors with a more meaningful understanding of our

ongoing and projected operating performance because this measure excludes (i) non-cash charges and benefits that are substantially dependent on changes in the market price of our common stock, (ii) non-cash interest charges related to the accounting for our outstanding convertible debt which are in excess of the actual interest expense owing on such convertible debt as well as non-cash interest charges related to our asset based loan which was terminated in 2017 and acquired Biotie debt, (iii) changes in the fair value of acquired contingent consideration which do not correlate to our actual cash payment obligations in the relevant period, (iv) acquisition related expenses and related foreign currency losses and gains that pertain to a non-recurring event, (v) corporate restructuring expenses that pertain to a non-recurring event, and (vi) asset impairment charges that pertain to a non-recurring event. The Company believes its non-GAAP net income measure helps indicate underlying trends in the Company's business and is important in comparing current results with prior period results and understanding projected operating performance.  Also, management uses this non-GAAP financial measure to establish budgets and operational goals, and to manage the Company's business and to evaluate its performance.

In addition to non-GAAP net income, we have provided 2017 guidance for R&D and SG&A on a non-GAAP basis. Due to the forward looking nature of this information, the amount of compensation charges and benefits needed to reconcile these measures to the most directly comparable GAAP financial measures is dependent on future changes in the market price of our common stock and is not available at this time.  The Company believes that these non-GAAP measures, when viewed in conjunction with our GAAP results, provide investors with a more meaningful understanding of our ongoing and projected R&D and SG&A expenses.  Also, management uses these non-GAAP financial measures to establish budgets and operational goals, and to manage the Company's business and to evaluate its performance.
