Private-equity firms had a blockbuster year for deal making, largely driven by technology investments.
As of mid-December, private-equity firms had announced backing U.S. technology deals totaling $401.71 billion, including new purchases, asset sales and add-on deals, according to data provider Dealogic. That accounted for 41% of a record $990.25 billion in overall private-equity deals through mid-December, Dealogic said.
