Release Date: 

Government contractor Parsons ( PSN ) plans to raise $500 million in the week's second-largest offering. The company has solid growth, a large market opportunity, an outstanding governance structure. Parsons is owned by its more than 15,000 employees through an employee stock ownership plan; the ESOP actually took the company private in 1984. The last government contractor was a micro-cap in 2014 (Sysorex), and before that Booz Allen in 2010.

The week's other ESOP-owned IPO, Mayville Engineering (MEC), is raising $125 million at a market cap of nearly $400 million. MEC manufactures industrial parts for commercial and industrial vehicles.
