July 10 — Under the terms of the Oncor deal, Sempra bought out the Texas utility’s previous owner, Energy Futures Holdings, which declared bankruptcy in 2014.

Energy Futures Holdings was beset by a number of financial problems, including complications due to falling natural gas prices. By contrast, Oncor has been a consistent moneymaker, posting a $431 million profit in 2016, and described by at least one analyst as a “jewel asset.”
