The sale of StarTex Power, a privately held retail electric provider based in Houston, to Constellation Energy of Baltimore benefits more than the two companies and the firms handling the $142.5 million transaction.

Employees of StarTex Power, founded in 2004, own about 30 percent of the company through an Employee Stock Ownership Plan launched in 2010. Marcie Zlotnik, chair of StarTex Power, writes in a press release that the employees’ interests are fully vested, so each will share financially in the proceeds of the sale.
