The first week of the second quarter got off to a nice start. We had one pricing, three new launches, and three initial filings / updates. This level of activity hasn't been seen since early 2016.Aeglea BioTherapeutics (NASADAQ: AGLE), raised $50 million by offering 5.0 million shares at $10. The company, which is developing enzymes for rare genetic metabolic diseases and tumors, ended up offering the shares significantly below the $16 to $18 range. This would normally worry investors but remember, like all biotechs so far this year, much of the deal was supported by insiders. In this case, over 60% of the deal.

Coming up:

This will be the first time in almost 2 months that we can say we had three companies set terms for their IPO's. The most exciting part is that, unlike previous names, all three of these companies are profitable!

First up was Bats Global Markets (BZX: BATS), an operator of securities exchanges in the US and Europe, set terms to raise $202 million, MGM Growth Properties (MGP  ), the MGM Resorts-backed REIT, set terms to raise nearly $1 billion, and American Renal Associates Holdings (ARA  ), an operator of 192 kidney dialysis clinics, set terms to raise $161 million.

Sign of good times to come?

 If all three of these names eventually price successfully, this would represent over $1.3 billion in proceeds. This total would represent nearly double this year's total.
