Dear WMG Shareholder:

It is my pleasure to invite you to our annual meeting, taking place on March 3, 2026. The attached proxy statement contains key information about the meeting’s agenda, as well as voting instructions.

We appreciate your important votes on the issues contained in this proxy statement.

In 2025, Warner Music Group successfully navigated a rapidly changing landscape while delivering profitable growth, improving our market share, and realigning our company for future success. We remained focused on the fundamentals that strengthen our business and protect the value of the music our artists and songwriters create and we continued to set the standard for artist development.

Innovation remained a central theme. Advances in AI brought new opportunities and new responsibilities, and our approach has been consistent. We support technological progress that respects artistic identity, operates with licensed data, and reflects the true value of music. Our partnerships and policy engagement this year continued to shape practical guardrails for the industry and reinforce a creator-first approach to innovation.

Throughout the year, we remained focused on running a disciplined, globally integrated organization. That means aligning strategic goals with execution, managing risk proactively, and operating efficiently across all parts of the company. These principles are core to how we grow market share, increase the value of music, and deliver durable performance while staying focused on what matters most: the music.

Against the backdrop of a healthy and growing industry that is seeing new opportunities emerge constantly, we are investing in our core music business to accelerate growth both organically and through accretive M&A. Additionally, we are improving efficiency to free up more capital to invest and enhance our margins all while focusing on thoughtful capital allocation.

As we look ahead, we remain confident in our strategy and in the opportunities ahead for music, technology, and global culture. Thank you to our artists, songwriters, partners, and teams who help drive this company forward. Together, we are building a Warner Music Group that is poised to deliver sustainable shareholder value.

On behalf of our Board of Directors, and our entire company, thank you for your support of WMG.

Sincerely,

Robert Kyncl

Chief Executive Officer

Warner Music Group Corp.
