 | Jul 17, 2017 03:11AM ET

Arena Pharmaceuticals, Inc.’s (NASDAQ:ARNA) shares jumped over 40% on Jul 11, after the company announced that a phase II study, evaluating its pipeline candidate ralinepag for treatment of pulmonary arterial hypertension (PAH), has met its primary endpoints.

However, the company’s shares declined 1% in after-hours trading on Tuesday, post its announcement that funds will be raised through an underwritten public offering.

Arena plans to offer and sell shares of its common stock worth $150 million, subject to customary closing conditions. The underwriters are expected to be granted with an option to buy up to 22.5 million additional common shares after deducting the underwriting discounts and commissions to cover over-allotments. The completion or the actual size or terms of the offering were not made public by the company.

Citigroup (NYSE:C), Leerink Partners, Cantor Fitzgerald & Co. and UBS Investment Bank are serving as joint book-running managers for the public offering.

Arena’s shares have significantly outperformed the Zacks classified Medical-Biomed/Genetics industry so far this year. Shares of the company surged 83.1%, while the industry registered an increase of 7.1%.
