24/7 Wall St.

Of the dozen initial public offerings (IPOs) scheduled for last week, all but one made it out the door. That one is now scheduled for the coming week along with one more that has been rescheduled after being delayed from a late March launch. And there’s just one new one in the barrel, so keeping track of what’s going on won’t be too difficult.

It’s worth noting that among last week’s IPOs, several priced at or below the expected range. The most prominent of these was Weibo Corp. (NASDAQ: WB), the Chinese Twitter, went out at $17 a share, the bottom of its range and started trading below that number before rebounding to $20.24. Investment bank Moelis & Co. (NYSE: MC) priced its IPO at $25, below the expected range of $26 to $29, and Opus Bank (NASDAQ: OP:B) priced fewer-than-expected shares at $30, below the anticipated range of $31 to $34. Moelis closed Thursday at $26.09, off 0.2%. Opus finished at $29.44, off 1.9% after two days of trading.

Delayed from last week is Quotient Ltd., a commercial-stage medical diagnostics firm, that plans to offer 5 million shares in its IPO.

Scynexis Inc. was first scheduled to launch at the end of March. The company is a development stage pharmaceutical firm currently developing a treatment for fungal infections in humans. The company originally planned to offer 4.2 million shares in an estimated price range of $12 to $14 a share.

Once launched, Scynexis will trade on the Nasdaq under the ticker symbol “SCYX”. Lead underwriters are RBC Capital Markets and Canaccord Genuity Inc.

Aldeyra Therapeutics is a development stage biotechnology company working on immune-mediated diseases thought to be caused by naturally occurring toxins known as free aldehydes. The company is planning to begin clinical testing for one such product this year.
