This Week's Upcoming IPO Calendar Breaks Three-Week Lull

upcoming ipo calendarAfter three weeks without a new issue, the IPO market is active again. There are three companies on this week's upcoming IPO calendar. They're expected to raise a combined $297 million.

The IPO market has been abnormally slow in 2015. There have only been 131 deals so far this year, down 37% from the same period in 2014. Most new issues have been healthcare firms. The number of tech IPOs has fallen to a seven-year low.

Stocks coming off new IPOs have faltered in the last two months. According to Renaissance Capital, a manager of IPO-focused ETFs, 47% of 2015 IPOs were trading below their offer price as of Aug. 21. If we're going to see a high volume of IPOs in Q4, new issues will need to start outperforming the broader market.

All three deals on this week's upcoming IPO calendar are biotech companies. One of them could become the largest medical products company to go public this year.

Here's everything you need to know about the offerings on this week's upcoming IPO calendar...

Nabriva Therapeutics AG (Nasdaq: NBRV) is set to begin Phase 3 trials for a class of antibiotics geared toward treating bacterial pneumonia. Nabriva boasts a leading drug candidate designated for Fast Track review by the U.S. Food and Drug Administration. Despite FDA favoritism, the candidate is years away from being approved and will face significant competition. Close peer Cempra Inc. (Nasdaq: CEMP) could impact Nabriva stock the most since Cempra also received Fast Track designation recently. Nabriva will generate $96 million by selling 6 million shares at a $15 to $17 price range. It commands a market valuation of $280 million and will hit the market on Friday, Sept. 18.
