Catalyst Receives Guidance From NASDAQ Regarding Minimum Bid Price Requirement

June 21, 2012 at 8:03 AM EDT

CORAL GABLES, Fla., June 21, 2012 (GLOBE NEWSWIRE) -- Catalyst Pharmaceutical Partners, Inc. (Nasdaq:CPRX) announced today that it received a Nasdaq Staff Deficiency Letter dated June 18, 2012 indicating that the Company is not in compliance with the Minimum Bid Price requirement set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on the Nasdaq Capital Market.

The Nasdaq Listing Rules (the "Rules") require listed securities to maintain a minimum bid price of $1.00 per share and, based upon the closing bid price for the last 30 consecutive business days, the Company no longer meets this requirement. In light of the deficiency, the Rules also provide the Company with a grace period of 180 calendar days in which to regain compliance. If at any time during this grace period the bid price of the Company's security closes at or above $1.00 per share for a minimum of ten consecutive business days, the Nasdaq Stock Market will provide the Company with a written confirmation of compliance and the matter will be closed.

In the event the Company does not regain compliance with the Rule prior to the expiration of the grace period, the Company may be eligible for an additional 180-day grace period if at such time it meets the initial listing standards for listing on the Nasdaq Capital Market, with the exception of the bid price requirement.

The Company understands the Nasdaq requirements and believes it will be able to regain compliance with the Rules within the allotted grace period.
