FOR IMMEDIATE RELEASE

Acorda Provides Update for First Quarter Ended March 31, 2019

ARDSLEY, NY – May 2, 2019 – Acorda Therapeutics, Inc. (NASDAQ: ACOR) provided a financial and pipeline update for the quarter ended March 31, 2019.

“Since INBRIJA became commercially available at the end of February, the feedback from both healthcare professionals and people with Parkinson’s, or PWPs, has been enthusiastic, and our Prescription Support Services center has received approximately 2,000 prescription requests. Our market research has consistently shown that both physicians and PWPs consider OFF periods one of the most troubling and disruptive aspects of Parkinson’s, and that they regard INBRIJA as having the potential to address this significant unmet need,” said Ron Cohen, M.D., Acorda's President and CEO. “We are currently meeting with insurers to discuss formulary placement. We are also continuing to roll out in-person and digital programs to educate healthcare professionals and PWPs about INBRIJA.”

First Quarter 2019 Financial Results

For the quarter ended March 31, 2019, the Company reported INBRIJA net revenue of $1.3 million. INBRIJA became commercially available on February 28, 2019.

For the quarter ended March 31, 2019, the Company reported AMPYRA net revenue of $40.1 million compared to $102.8 million for the same quarter in 2018. In September 2018, AMPYRA lost its exclusivity and generics entered the market. Consequently, the Company expects AMPYRA revenue to continue to decline.

Research and development (R&D) expenses for the quarter ended March 31, 2019 were $16.0 million, including $0.7 million of share-based compensation compared to $30.6 million, including $1.7 million of share-based compensation for the same quarter in 2018.

Sales, general and administrative (SG&A) expenses for the quarter ended March 31, 2019 were $52.7 million, including $2.8 million of share-based compensation compared to $47.6 million, including $4.2 million of share-based compensation for the same quarter in 2018.

Benefit from income taxes for the quarter ended March 31, 2019 was $0.7 million compared to a provision for income taxes of $3.5 million for the same quarter in 2018.

The Company reported a GAAP net loss of $47.6 million for the quarter ended March 31, 2019, or $1.00 per diluted share. GAAP net loss in the same quarter of 2018 was $8.2 million, or $0.18 per diluted share.

Non-GAAP net loss for the quarter ended March 31, 2019 was $26.5 million, or $0.56 per diluted share. Non-GAAP net income in the same quarter of 2018 was $6.8 million, or $0.14 per diluted share. This quarterly non-GAAP net (loss) income measure, more fully described below under “Non-GAAP Financial Measures,” excludes share-based compensation charges, non-cash interest charges on our debt, and changes in the fair value of acquired contingent consideration. A reconciliation of the GAAP financial results to non-GAAP financial results is included with the attached financial statements.

At March 31, 2019, the Company had cash, cash equivalents and short-term investments of $343.3 million compared to $445.6 million at year end 2018. The decline in cash was due in large part to non-recurring payments of approximately $45 million that were made in the first quarter, primarily related to AMPYRA inventory purchases. The Company does not expect to purchase additional AMPYRA inventory in 2019.

For the remainder of 2019, the Company expects cash expenditures to align with normal operating activities, and continues to believe that it can become cash flow positive without raising additional capital, based on its long-term projections.

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 loss, adjusted to exclude the items below, and has provided 2019 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 loss, 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, and acquired Biotie debt, and (iii) changes in the fair value of acquired contingent consideration which do not correlate to our actual cash payment obligations in the relevant periods. The Company believes its non-GAAP net loss 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 loss, we have provided 2019 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: we may not be able to 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; third party payers (including governmental agencies) may not reimburse for the use of Inbrija or our other products at acceptable rates or at all and may impose restrictive prior authorization requirements that limit or block prescriptions; competition for Inbrija, Ampyra and other products we may develop and market in the future, including increasing competition and accompanying loss of revenues in the U.S. from generic versions of Ampyra (dalfampridine) following our loss of patent exclusivity; 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; 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 ; 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; 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.
