Long Lake to Buy Amex GBT for $6.3 Billion

The all-cash deal would take a New York-listed corporate travel platform private, with major shareholders already lined up and antitrust clearance still ahead.

New York, New York - Long Lake Management agreed to acquire Global Business Travel Group, the operator of American Express Global Business Travel, for about $6.3 billion in cash, according to a Form 8-K filed Monday with the Securities and Exchange Commission.

The agreement gives GBTG shareholders $9.50 a share in cash, according to the company press release filed as Exhibit 99.1. The filing says that price is 60.2% above the stock's May 1 close and about 65.1% above its 30-day volume weighted average price ending May 1.

The deal matters because it moves one of the largest corporate travel platforms from the public markets into private ownership at the same moment investors are funding automation across service industries. It also gives U.S. regulators a role before closing, because the Form 8-K lists Hart-Scott-Rodino waiting period expiration or termination and certain foreign investment approvals as closing conditions.

The Story So Far

Global Business Travel Group operates American Express Global Business Travel, but Long Lake is not buying American Express Company. The company release says American Express is a major shareholder, and the American Express brand licensing agreement will remain in place after the transaction if the merger closes.

The 2025 Form 10-K shows the scale behind the price tag. Amex GBT generated about $36.3 billion in total transaction value in 2025, with $2.72 billion in revenue, $111 million in net income, and $532 million in adjusted EBITDA, according to the annual filing.

The 10-K also says the company had more than 27,000 employees worldwide and a proprietary presence or operations in 49 countries as of Dec. 31, 2025. The filing says those 49 countries represented about 92% of worldwide business travel spend, citing the Global Business Travel Association.

Long Lake was founded in 2023 and says it uses frontier technology to accelerate services industries, according to the May 4 company release. The release says Long Lake is backed by General Catalyst, Alpha Wave, Elad Gil, D1, Thrive, and other investors.

What's Happening Now

The merger agreement was signed May 2 by Global Business Travel Group, Gaia Purchaser, and Gaia Merger Sub, according to the Form 8-K. The filing says Gaia Merger Sub will merge into Global Business Travel Group, with the company surviving as a wholly owned subsidiary of Gaia Purchaser.

The merger agreement says the board created a special committee made up only of independent and disinterested directors to review, evaluate, and negotiate the transaction. The Form 8-K says the special committee unanimously determined that the deal was fair, advisable, and in the best interests of the company and its stockholders.

The shareholder vote may be the least uncertain part of the process. American Express, Expedia, Qatar Investment Authority, and BlackRock signed voting agreements supporting the transaction, according to the company release. The same release says those shareholders collectively represent 69% of GBT's shares.

The company release says the transaction is expected to close in the second half of 2026, subject to stockholder approval and required regulatory clearances. The Form 8-K says the deal cannot close before July 1, 2026, even if other conditions are met sooner.

The release says the transaction is not subject to a financing condition. Long Lake plans to fund the purchase with equity from its existing investors and Koch Equity Development, plus committed debt financing from JPMorgan, Bank of America, Citi, and MUFG, according to the release.

The Conservative View

The market-oriented case for the deal starts with the premium and the committed vote. The company release says public shareholders would receive certain cash value at $9.50 a share, while holders of 69% of the shares have already agreed to support the transaction.

Supporters of private ownership often argue that a company can make operational changes faster outside quarterly public-market scrutiny. In this case, Long Lake's own statement frames the purchase around applying AI to service work, while the company release says the American Express brand license will remain in place for clients, partners, and travelers.

Paul Abbott, Amex GBT's chief executive, said the agreement gives shareholders a certain cash outcome and pairs the company with Long Lake's technology capabilities.

"This transaction is a testament to the value of Amex GBT, the success of our strategy and the strength of our incredible team." - Paul Abbott, Chief Executive Officer of Amex GBT

The Progressive View

The labor and regulatory questions begin with the same facts. The 2025 Form 10-K says Amex GBT had more than 27,000 employees worldwide, while Long Lake's public thesis centers on AI and human agents working together in travel services.

No filing reviewed Monday disclosed layoffs, office closures, or quantified workforce changes tied to the merger. That absence matters because the company release describes faster booking times, proactive disruption resolution, and travel administration as target areas for AI-enabled service work.

Regulatory review is also not optional. The FTC says the Hart-Scott-Rodino Act requires parties to certain large mergers and acquisitions to submit premerger notification to the FTC and Justice Department, and that parties may not close until the waiting period has passed or early termination has been granted.

The Form 8-K does not disclose an FTC or Justice Department challenge, a second request, or any agency position on the deal. It does say HSR waiting period expiration or termination and certain foreign investment approvals are closing conditions.

Other Perspectives

For shareholders, the deal is a near-term cash exit at a large premium to recent trading prices, according to the company release. For clients, the most important continuity point is the company statement that the American Express brand licensing agreement will remain in place.

For lenders, the transaction is another large private acquisition backed by named banks. The release identifies JPMorgan, Bank of America, Citi, and MUFG as providers of committed debt financing, but it does not disclose debt ratios, interest expense, or covenant terms.

For international partners, the transaction changes the ownership structure of a corporate travel platform that operates across dozens of countries. The 10-K says Amex GBT has operations or a proprietary presence in 49 countries, while the Form 8-K says certain foreign investment approvals are required before closing.

Economic Implications

The acquisition price puts a $6.3 billion value on a company that produced $2.72 billion in 2025 revenue and $532 million in adjusted EBITDA, according to the 2025 Form 10-K and the May 4 company release. On those figures, the transaction value equals about 2.3 times 2025 revenue and about 11.8 times 2025 adjusted EBITDA.

The economic mechanism is not leisure travel demand. It is corporate travel infrastructure, bank-financed private capital, and service automation. Amex GBT's 2025 total transaction value of about $36.3 billion shows the company sits between corporate clients, travel suppliers, meetings and events spending, and expense-management workflows, according to the 10-K.

The financing structure also ties the deal to U.S. credit markets. The release says Koch Equity Development and Long Lake investors are providing equity, while JPMorgan, Bank of America, Citi, and MUFG are providing committed debt financing. The release does not disclose how much debt each bank committed, so any effect on bank exposure or the company's post-closing interest burden remains undisclosed.

The employment question is similarly bounded by the filings. The 10-K discloses more than 27,000 employees worldwide, and Long Lake's CEO said AI and human agents will work together in future business travel service. The filings do not disclose job cuts, severance plans, or location changes.

By the Numbers

• $6.3 billion, approximate all-cash transaction value, according to Exhibit 99.1 filed with the SEC on May 4.
• $9.50 a share, the cash price for GBTG shareholders under the merger agreement, according to the Form 8-K.
• 60.2%, the premium to GBTG's May 1 closing stock price, according to the company release.
• 69%, the share base covered by voting agreements from American Express, Expedia, Qatar Investment Authority, and BlackRock, according to the company release.
• $36.3 billion, Amex GBT's 2025 total transaction value, according to the company's 2025 Form 10-K.

What People Are Saying

"This agreement delivers a compelling outcome for our shareholders, providing them a substantial, certain cash value at an attractive premium." - Paul Abbott, Chief Executive Officer of Amex GBT

"American Express Global Business Travel was built on trust earned over decades. Similarly, the foundation of the Long Lake model is a strong commitment to extraordinary customer service for the modern era."

Ken Chenault, Chairman and Managing Director of General Catalyst and former Chairman and CEO of American Express

"The future of business travel will be defined by AI and human agents working seamlessly together on behalf of every traveler: faster booking times, proactive disruption resolution, and frictionless travel administration." - Alex Taubman, Co-Founder and CEO of Long Lake

"The parties may not close their deal until the waiting period outlined in the HSR Act has passed, or the government has granted early termination of the waiting period." - Federal Trade Commission, Premerger Notification Program guidance

The Big Picture

The next document to watch is the proxy statement. The Form 8-K says stockholder approval is required, and the company release says Long Lake may discuss potential rollover agreements with certain significant stockholders before the transaction closes.

Regulators have not announced a challenge based on the filings reviewed Monday. The disclosed approval path includes the HSR waiting period, certain foreign investment approvals, and other customary closing conditions.

If the merger closes, Global Business Travel Group's common stock will no longer trade publicly, according to the company release. That would shift scrutiny of a major corporate travel platform from quarterly public filings toward private owners, lenders, regulators, customers, and employees.
