FIS

Announced May 20, 2026, from Jacksonville. FIS announced that BankSouth, a $1.6 billion-asset community bank based at Lake Oconee, Georgia, selected the FIS core banking platform to power its retail and business banking lines. The bank framed the conversion as part of a broader data and technology strategy. The selection followed BankSouth's March 2026 announcement of a strategic partnership with Sequence Holdings, the permanent holding company deploying engineers and AI tooling into the bank's operations, and coverage connected the two moves as parts of the same modernization effort.

Announced May 4, 2026. Long Lake Management agreed to acquire American Express Global Business Travel in an all-cash take-private valued at approximately $6.3 billion, with support from General Catalyst and Alpha Wave; Koch Equity Development was also reported in the syndicate. Shareholders receive $9.50 per share, a 60.2 percent premium to the May 1 closing price. The transaction is expected to close in the second half of 2026, subject to customary conditions and regulatory clearances. American Express is selling its roughly 30 percent stake for $1.5 billion and expects to record a pre-tax gain of about $975 million; its brand license and other commercial agreements with Amex GBT remain in place. Paul Abbott is chief executive of Amex GBT, which operates in more than 140 countries. Ken Chenault, General Catalyst chairman and former American Express chief executive, commented on the deal. Long Lake was founded in 2023.

BankSouth — Sequence partnershipCompany announcementExcerpt
BankSouth

Announced March 2026, from Greensboro, Georgia. BankSouth, a $1.6 billion-asset community bank, announced a strategic partnership with Sequence Holdings, a permanent holding company that improves the operations of established businesses through technology. Under the partnership, a team of Sequence engineers — with backgrounds at Palantir, Scale AI, and Apple — works alongside BankSouth's staff to build and deploy AI-powered tools, framed around a human-first approach to community banking and BankSouth's roughly 80-year history. Sequence chief executive Michael Lee, a financial services and technology investor, joined BankSouth's board of directors. Sequence took a minority position in the bank. The partnership followed Sequence's emergence from stealth with a $75 million seed round led by Conviction and 8VC and a Series A led by Lux Capital, joined by Definition, Avenir, Chris Ré, and other institutional investors. Sequence is based in New York and deploys engineers alongside a proprietary technology platform. Latham & Watkins represented Sequence on both the partnership and the financings.
