What happened Clinical-stage biotech Immunic (NASDAQ: IMUX) was not immune to the market's ire on Thursday. The company announced a planned new share issue that had many investors heading to the exits, and drove the stock down by more than 21% on the day. So what Immunic aims to raise gross proceeds of around $45 million by selling 4.5 million shares of common stock at $10 apiece in an underwritten public offering. That price is significantly under the $11.94 closing price of the stock on Wednesday. Image source: Getty Images. The underwriting syndicate, led by Piper Sandler (NYSE: PIPR), has been granted a 30-day option to buy up to an extra 675,000 shares among themselves. Immunic anticipates that this flotation will close on or about July 19. The biotech said it will use the funds raised to continue the development of its three product candidates, all of which are immunology treatments that could potentially be effective against a variety of afflictions including multiple sclerosis and Crohn's disease. The most promising of the trio, IMU-838, tested well in a phase 2 clinical trial evaluating its effect on relapsing-remitting multiple sclerosis. Now what While Immunic has certainly delivered good news for its investors in the past, a 4.5 million share issue is quite a big pill to swallow. The company's share count, according to Yahoo! Finance, is under 21.8 million, so this secondary issue will cause current shareholders significant dilution. Hopefully for those investors who are hanging on or coming in on stock price weakness, Immunic will put those funds to productive use. 10 stocks we like better than Immunic, Inc.When our award-winning analyst team has a stock tip, it can pay to listen.
