FOR IMMEDIATE RELEASE

Acorda Provides Financial and Pipeline Update for First Quarter 2018

ARDSLEY, NY – May 2, 2018 – Acorda Therapeutics, Inc. (Nasdaq: ACOR) provided a financial and pipeline update for the quarter ended March 31, 2018.

“With FDA’s acceptance of Acorda’s NDA for INBRIJA and a PDUFA date of October 5, 2018, we are focused on preparations for the potential U.S. approval and launch,” said Ron Cohen, M.D., Acorda's President and CEO. “We are also looking forward to the opportunity to argue our case for our AMPYRA patents at the U.S. Court of Appeals on June 7.”

First Quarter 2018 Financial Results

AMPYRA^® (dalfampridine) Extended Release Tablets, 10 mg - For the quarter ended March 31, 2018, the Company reported AMPYRA net revenue of $102.8 million compared to $112.0 million for the same quarter in 2017. The quarter over quarter reduction in net revenue was primarily related to a modest expansion in customer inventories in the fourth quarter 2017 which normalized by the end of the first quarter 2018.

Research and development (R&D) expenses for the quarter ended March 31, 2018 were $30.6 million, including $1.7 million of share-based compensation compared to $46.5 million, including $2.5 million of share-based compensation for the same quarter in 2017. Quarter-over-quarter reductions in R&D expenses are primarily the result of our corporate restructuring which occurred in 2017.

Sales, general and administrative (SG&A) expenses for the quarter ended March 31, 2018 were $47.6 million, including $4.2 million of share-based compensation compared to $52.0 million, including $5.3 million of share-based compensation for the same quarter in 2017. Quarter-over-

quarter reductions in SG&A expenses are primarily the result of our corporate restructuring which occurred in 2017.

Provision for income taxes for the quarter ended March 31, 2018 was $3.5 million, including $0.5 million of cash taxes, compared to a benefit from income taxes of $0.9 million, including $1.9 million of cash taxes for the same quarter in 2017.

The Company reported a GAAP net loss of $8.2 million for the quarter ended March 31, 2018, or $0.18 per diluted share. GAAP net loss in the same quarter of 2017 was $18.9 million, or $0.41 per diluted share.

Non-GAAP net income for the quarter ended March 31, 2018 was $6.8 million, or $0.14 per diluted share. Non-GAAP net loss in the same quarter of 2017 was $3.6 million, or $0.08 per diluted share. This quarterly non-GAAP net income (loss) measure, more fully described below under “Non-GAAP Financial Measures,” excludes share-based compensation charges, non-cash interest charges on our debt, changes in the fair value of acquired contingent consideration, and acquisition-related expenses. A reconciliation of the GAAP financial results to non-GAAP financial results is included with the attached financial statements.

At March 31, 2018, the Company had cash, cash equivalents and short-term investments of $333.0 million.

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 2018 guidance for R&D and SG&A expenses 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 compensation 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 related to the Fampyra monetization, 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 periods, and (iv) acquisition related expenses and related foreign currency losses and gains 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 2018 guidance for R&D and SG&A expenses 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.

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 acquisitions, 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; 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 (levodopa inhalation powder) 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 or any other products under development; risks associated with complex, regulated manufacturing processes for pharmaceuticals, which could affect whether we have sufficient commercial supply of Inbrija to meet market demand, if it receives regulatory approval; 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; the outcome (by judgment or settlement) and costs of legal, administrative or regulatory proceedings, investigations or inspections, including, without limitation, collective, representative or class action litigation; 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.
