• SEC Filings

On April 11, 2018, ARCA biopharma, Inc. (“ARCA”) received a notice (the “Notice”) from The Nasdaq Stock Market (“NASDAQ”) indicating that ARCA’s common stock (the “Common Stock”) does not meet the continued listing requirement as set forth in NASDAQ Rule 5550(a)(2) based on the closing bid price of the Common Stock for the preceding 30 business days. The minimum closing bid price required to maintain continued listing on The Nasdaq Capital Market is $1.00 per share.

Under NASDAQ Rule 5810(c)(3)(A), ARCA has a 180 calendar day grace period from the date of the Notice to regain compliance by meeting the continued listing standard. The continued listing standard will be met if the Common Stock has a minimum closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days during the 180 calendar day grace period. If ARCA does not regain compliance within the 180 calendar day grace period, it may be afforded an additional 180 calendar day compliance period, provided that on the 180^th day of the first grace period ARCA (i)meets the applicable market value of publicly held shares requirement for continued listing and all other applicable requirements for initial listing on The Nasdaq Capital Market (except for the bid price requirement) based on ARCA’s most recent public filings and market information and (ii)notifies NASDAQ of its intent to cure this deficiency. If ARCA does not indicate its intent to cure the deficiency or if it does not appear to NASDAQ that it would be possible for ARCA to cure the deficiency, ARCA would not be eligible for the second 180 day compliance period, and its securities would then be subject to delisting from the Nasdaq Capital Market. If ARCA is unable to regain compliance during the first 180 calendar day grace period or, if applicable, the second 180 day compliance period, and receives a delisting determination from NASDAQ it may, at that time, request a hearing to remain on The Nasdaq Capital Market, which request will ordinarily suspend such delisting determination until a decision by NASDAQ subsequent to the hearing.

There can be no assurance that ARCA will be successful in maintaining its listing of the Common Stock on The Nasdaq Capital Market. This could impair the liquidity and market price of the Common Stock. In addition, the delisting of the Common Stock from a national exchange could materially adversely affect the ARCA’s access to capital markets, and any limitation on market liquidity or reduction in the price of the Common Stock as a result of that delisting could adversely affect ARCA’s ability to raise capital on terms acceptable to ARCA, or at all.

About ARCA biopharma, Inc. (NASDAQ:ABIO)

ARCA biopharma, Inc. (ARCA) is a biopharmaceutical company. The Company is principally focused on developing genetically-targeted therapies for cardiovascular diseases. The Company’s lead product candidate is Gencaro (bucindolol hydrochloride), a beta-blocker and mild vasodilator that the Company is evaluating in a clinical trial for the treatment of atrial fibrillation (AF) in patients with heart failure with reduced left ventricular ejection fraction (HFREF). Gencaro is considered part of the beta-blocker class of compounds because of its property of blocking both beta-1 and beta-2, receptors in the heart. The blocking of these receptors prevents the receptor from binding with other molecules, primarily the neurotransmitter norepinephrine (NE), which activate these receptors. The Company is conducting a Phase IIB/III clinical trial of Gencaro, known as GENETIC-AF.
