Marinus Announces One-for-Four Reverse Stock Split

- Shares of Common Stock Will Begin Trading on Split-Adjusted Basis on September 23, 2020

RADNOR, Pa.--()--Marinus Pharmaceuticals, Inc. (Nasdaq: MRNS), a pharmaceutical company dedicated to the development of innovative therapeutics to treat rare seizure disorders, today announced that it will effect a one-for-four reverse stock split of its common stock at 5:00 pm ET today. Beginning with the opening of trading on September 23, 2020, the Company’s common stock will trade on The Nasdaq Global Market on a split-adjusted basis under a new CUSIP number 56854Q200.

The Company’s stockholders approved an amendment authorizing the reverse stock split at its Special Meeting of Stockholders on March 31, 2020. The reverse stock split was effected by filing a Certificate of Amendment to the Company's Restated Certificate of Incorporation with the Secretary of State of the State of Delaware.

The reverse stock split will be effected simultaneously for all outstanding shares of common stock and the ratio will be the same for all outstanding shares of common stock. The reverse stock split will affect all holders of shares of Marinus common stock uniformly and each stockholder will hold the same percentage of Marinus common stock outstanding immediately following the reverse stock split as that stockholder held immediately prior to the reverse stock split, except for adjustments that may result from the treatment of fractional shares as described below.

No fractional shares will be issued in connection with the reverse stock split. Stockholders who would otherwise be entitled to receive a fractional share will instead receive a cash payment based on the closing sales price of the Company’s common stock on September 22, 2020.

The reverse stock split proportionately reduces the number of shares of common stock available for issuance under the Company’s equity incentive plans and proportionately reduces the number of shares of common stock issuable upon the exercise of stock options outstanding immediately prior to the reverse split. The reverse stock split will reduce the number of shares of common stock issued and outstanding from approximately 122.3 million to approximately 30.6 million.

In connection with the reverse stock split, the number of authorized shares of common stock will be decreased from 300,000,000 to 150,000,000, effective immediately following the effectiveness of the reverse split. There will be no change to the number of authorized shares of preferred stock, or change in the par values of Company’s common stock (which will remain at $0.001 per share) or preferred stock (which will remain at $0.001 per share).

American Stock Transfer & Trust Company, LLC (AST) is acting as the exchange agent and transfer agent for the reverse stock split. AST will provide instructions to stockholders with physical certificates regarding the process for exchanging their pre-split stock certificates for post-split shares in book-entry form and receiving payment for any fractional shares.
