Cat Kreidich, president of Warner Music Groups music distribution arm ADA, is leaving the company, she confirmed in an internal memo to staff on Tuesday.

Kreidich leaves after four years at the helm at ADA. WMG hasnt provided any details on Kreidichs successor. In a note to staff, WMG CEO Robert Kyncl said the company would have an update on ADAs leadership this week. In Kreidichs memo, reviewed by The Hollywood Reporter, she said that while Im not ready to announce my next chapter, I look forward to sharing those plans when appropriate. While organizational change is a constant in our industry, I believe the foundation weve established will continue to serve independent artists effectively, Kreidich wrote in her memo. We built an exceptional global team and expanded our global release volume, revitalized our brand identity, and developed a digital platform specifically designed for independent artists and labels within the Warner supply chain. We made strategic acquisitions like RSDL, which Warner will go on to use to help fuel their entire recorded music business.

Prior to ADA, Kreidich was an executive at The Orchard, Sony Music Groups distribution arm. During her tenure as ADA president, shed closed distribution deals with Three Six Zero Recordings and Rostrum Records, as well as Keshas famed distribution deal as the pop star decided to go independent.

When I returned four years ago as an executive from The Orchard and Sony, I brought a vision to recapture that pioneering spirit and transform ADA to better compete in an increasingly crowded landscape of innovative music technology companies, Kreidich wrote Tuesday. We didnt aspire to be the biggest distribution company, but rather the most valuable valuable to our artist and label partners by offering expert guidance and measurable results, and valuable to Warner Music Group by helping build its ecosystem and reputation for supporting independent artists.

Kreidichs departure comes as distribution companies have become an area of increased attention across the industry. Back in December, Universal Music Groups Virgin Music Group announced a deal to acquire Downtown Music Group Holdings, the parent company to music distributors FUGA and CD Baby. (That deal is currently facing regulatory scrutiny from EU authorities, Reuters reported.) Concord, meanwhile, closed on a deal for indie distributor Stem back in March.

Kreidichs departure is just the latest notable shift at WMG; earlier this month, Kyncl had announced a $300 million cost-saving initiative which included a $170 million cut through headcount reduction.

Cat is a class act, Kyncl wrote in his note Tuesday. A bold thinker and decisive leader, shes always focused on whats best for the indie community its artists, its labels, and its spirit. Under her leadership, ADA has grown its relationships across the creative ecosystem, expanded its global reach, and strengthened its team and tech. Shes helped guide us through some major shifts, staying agile, and delivering results.

To the ADA Team,

I wanted you to hear this news directly from me: After four transformative years proving that Warner Music Group and ADA can truly be the best home for independent artists and labels, I have made the decision to leave the company. While organizational change is a constant in our industry, I believe the foundation weve established will continue to serve independent artists effectively.

We built an exceptional global team and expanded our global release volume, revitalized our brand identity, and developed a digital platform specifically designed for independent artists and labels within the Warner supply chain. We made strategic acquisitions like RSDL, which Warner will go on to use to help fuel their entire recorded music business.

This journey represents my second chapter with ADA. My first began during the early years of digital transformation, when I transitioned from a music tech startup. Having completed one of the first of its kind New Media degrees at Emerson College, I was drawn to the possibilities of digital disruption and the independent music scene. When I came across ADA in the 00s, it was supporting breaking independent acts at an unprecedented scale, pioneering new approaches while music was being democratized globally through emerging digital platforms like iTunes, eMusic, and mobile entertainment.

When I returned four years ago as an executive from The Orchard and Sony, I brought a vision to recapture that pioneering spirit and transform ADA to better compete in an increasingly crowded landscape of innovative music technology companies. We didnt aspire to be the biggest distribution company, but rather the most valuablevaluable to our artist and label partners by offering expert guidance and measurable results, and valuable to Warner Music Group by helping build its ecosystem and reputation for supporting independent artists. We believed that Warner Music Group and ADA were better together, each strengthening the others capabilities and reach, and I think weve proven that out. As the company begins its next chapter, WMG is committed to continuing to expand the depth and range of ADAs services.

To the ADA labels and artists who keep the heart of this industry beating: thank you for your dedication, creativity, and passion. Ive been inspired by your relentless drive and your vision. You champion creativity, and prove that independence doesnt mean going it aloneit means doing it your way. You are shaping the future of music, and I remain passionate about the independent music community and will continue to champion its growing importance.

While Im not ready to announce my next chapter, I look forward to sharing those plans when appropriate it will be consistent with the work I have been grateful to do for the last 20 years as an indie advocate.

With gratitude and appreciation,

CAT
