SOUTHLAKE, Texas and LONDON, United Kingdom, Feb. 29, 2024 – Travalyst, the not-for-profit organization founded by Prince Harry, The Duke of Sussex, today welcomes Sabre and Mastercard to its coalition. Sabre Corporation (NASDAQ: SABR) and Mastercard join other leading travel and technology brands in the Travalyst coalition including Amadeus, Booking.com, Expedia Group, Google, Skyscanner, Travelport, Trip.com Group, Tripadvisor and Visa. The group, which represents a combined market cap of almost $3tn, aims to bring sustainability information to the mainstream to help people make better travel choices. The addition of Mastercard and Sabre will help accelerate that ambition. Brad West, Head of Partnerships, Travalyst said, “The addition of Mastercard and Sabre aligns with our partnerships strategy and adds further scale to our mission. Bringing a payments technology leader on board, as well as enhancing our presence among key technology providers to the travel industry, means we are strategically poised to deliver on our mission to mainstream sustainability information within the travel industry to help drive change.” “At Mastercard, we envision a world where each swipe, click or tap provides businesses and consumers with the opportunity to make more sustainable choices,” said Chad Wallace, global head of Commercial Solutions, Mastercard. “By joining the Travalyst coalition, we can further activate the power of our global network, insights and technologies to empower travelers to better understand the environmental impact of their business and leisure trips.” Kristin Hays, Chief Communications and Sustainability Officer, Sabre said, “We’re committed to taking on the biggest opportunities and solving the most complex challenges in travel, so we’re thrilled to be joining forces with Travalyst and our peers in the industry to help drive more sustainable travel decisions.” Consumers want to travel more sustainably¹ and sustainability is a top priority for the corporate travel industry² as well. Travalyst works to deliver clear, consistent and credible sustainability information, at scale, to enable people to make better travel choices. For example, the same flight emissions estimates are now available across the majority of Travalyst’s partner platforms. The lower-emitting flight is flagged which empowers the person booking travel to select a flight with lower-than-average emissions, reducing the impact of their trip. Providing consistent sustainability information is key to driving travelers’ trust. Striving to transform the travel industry into a more sustainable one, by providing people with sustainability information, is a shared journey and both Mastercard and Sabre are fully aligned with Travalyst’s mission. ### About Sabre Corporation Sabre Corporation is a leading software and technology company that powers the global travel industry, serving a wide range of travel companies including airlines, hoteliers, travel agencies and other suppliers.
