Global Payments' (GPN - Get Report) $21.5 billion all-stock acquisition of Total Payments (TSS) announced Tuesday may not be the last deal Global Payments makes in the near future, the company's chief financial officer Cameron Bready told TheStreet.

"Naturally, we're always looking to add new businesses to the combined company that are going to help us expand into new markets, to bring new capabilities, to continue to allow us to differentiate global payments relative to the competition in the markets that we operate in," Bready said. "Today, we're very focused on making this deal work." He said the currently $23.6 billion market cap company will focus the next 12 to 18 months on integrating Total Payments into the combined business.

"But ultimately, we're going to get back to reinvesting in the business and that's not going to be in the too distant future," Bready added. "In the next 12 to 18 months, we're going to start to work to deploy more capital again towards more software, more vertical market solutions, and more and more investments in technologies."

Some of that capital deployment, as Bready alluded to, could be in the form of both internal investment and acquisitions. "The reality is, it's both."

The deal sent Total Payments' stock up 5.6% to $119.80 a share Tuesday. In the deal, Total Payments shareholders will receive 0.8101 Global Payments shares, or $119.86 apiece, for each Total Payments share.

The deal comes after Global Payments acquired Heartland Payment System for $4.3 billion in cash and stock in 2016. As the adoption of digital payments proliferates, large banks with tons of cash to spend are positioning to be more than sufficient in the space. Meanwhile, PayPal (PYPL - Get Report) , one of the pioneers of digital payments acquired Venmo in 2013, and is now worth $132 billion. The digital payments market is positioned to grow 13.7% annually in the U.S. through 2024, according to a report from Research and Markets. China's growth rate of payments is expected be 18.5% annually through 2023, according to data aggregated by Statista.

"As it relates to the digital trends that we see across Asia, around more and more commerce being effectuated with digital forms of payment, we're very well positioned as a combined company to benefit from that trend," Bready said.
