Payments are a critical and often overlooked part of the global economy. Georgia is the payments capital of the U.S., processing some 70 percent of all debit, credit and gift card transaction in the nation each year, according to the American Transaction Processors Coalition.

First Data is based in a tower along Ga. 400 in Sandy Springs and Fiserv has significant operations in Alpharetta.

The impact of the deal on metro Atlanta isn’t clear, but cost “synergies” — often meaning job reductions — are among the motivating factors of this transaction.

In the news release, the companies said they expect the merger to create about $900 million in “cost synergy savings over five years, driven primarily by the elimination of duplicative corporate structures, streamlined technology infrastructure, increased operational efficiencies, process improvements, and footprint optimization.”

Those cost savings, the release said, would be “achieved across the combined organization.”

Roger Tutterow, a Kennesaw State University economist, said mergers often lead to job cuts and other operational changes, but he said metro Atlanta’s status as financial technology, or FinTech, hub will hopefully blunt any impact from this corporate marriage.

“I wouldn’t panic,” Tutterow said. “I think Atlanta’s status as a hub for FinTech clearly lowers the risk of a massive scale back here in Atlanta. …There may be more management overlap than there is in products.”

The $22 billion price for First Data amounts to about a 30 percent premium to the company’s recent share price over the past five days, the release said.
