CALLAWAY GOLF COMPANY ANNOUNCES THE RETURN OF HARRY ARNETT AS SENIOR VICE PRESIDENT, CHIEF BRAND OFFICER

Callaway Golf Company (the "Company," "Callaway," "we," "our," "us") (NYSE: CALY ) announced today that Harry Arnett has been appointed as Senior Vice President, Chief Brand Officer. Mr. Arnett previously worked for Callaway from 2012 – 2019 as its head of global brand and marketing. In this new role, Arnett will lead Callaway's global brand strategy and demand-creation efforts, bringing together brand building, creative communications, and all consumer-facing strategies to strengthen the Company's connection with golfers, generate greater momentum around its products, and drive market-share growth. "We are very excited to have Harry return home to his Callaway family," commented Chip Brewer, President and Chief Executive Officer of Callaway. "Harry brings a rare combination of creative vision, commercial instinct, and a deep understanding of the golf consumer. During Harry's first chapter with Callaway, he helped establish a more modern, consumer-focused approach to brand building and demand creation that contributed to Callaway's resurgence as a leader in the golf industry. During that time, our U.S. hard goods dollar market share, as reported by Golf DataTech, increased over 1,000 basis points to 24.0%, we re-claimed the # 1 US club brand position from 2015 - 2020, and we began our market share climb in golf balls that continues to this day. We are excited about what we can accomplish together in this next chapter." "Coming back to Callaway means a great deal to me and my family," said Harry Arnett. "I've long believed Callaway is one of the truly iconic brands in all of sports, and I couldn't be more excited to reunite with the incredible people who make Callaway special. The team has done tremendous work sharpening the Company's focus on golf and putting it in a strong position for its next chapter. Now we have an opportunity to build on that momentum, create new energy around the brand, deepen our connection with golfers, and take Callaway to an entirely different level. I can't wait to roll up my sleeves and get to work with the team." Forward-Looking Statements .
