UPPER SAUCON TWP., Pa. – Payment processing company Shift4 is looking to expand its portfolio again.

It has started the process of buying the North American assets of the French payment processing company Worldline.

Shift 4 is seeking to acquire Bambora Inc., Bambora Holding Corp, Bambora Corp, and Worldline SMB US, all of which are collectively known as Bambora North America.

The deal is expected to close in the first quarter of 2026, subject to the usual customary approvals.

A purchase price was not disclosed.

Bambora North America serves over 140,000 merchants across the United States and Canada, with a gateway that supports a mix of online and in-person payments, Shift4 said in a news release.

“This is a textbook Shift4 acquisition, delivering a massive funnel of gateway customers and payments volume to cross-sell onto our global acquiring platform,” said Shift4 CEO Taylor Lauber, in the release. “This deal is similar to past transactions that have enabled us to rapidly grow our customer base by offering these merchants significant value and a better payments experience with a streamlined end-to-end commerce solution.”

Shift4, headquartered in Upper Saucon Township, has announced a number of acquisitions in recent months. In February, the company said it would buy the Swiss financial technology company Global Blue in a $2.5 billion deal.

In June, Shift4 signed an agreement to acquire Smartpay, a payment processing and point-of-sale solutions company that does business in Australia and New Zealand.

Shares of Shift4 stock (NYSE: FOUR) were trading at $75.36 late Wednesday afternoon. That’s near the bottom of their 52-week range.

The company will release its fiscal 2025 third quarter financial results on November 6.
