Warner Music reported digital revenue growth across its recorded music and music publishing businesses, offset partly by a decline in recorded music artist services (concerts) and expanded-rights and licensing.
The company sees "continued momentum ... in streaming and the operating leverage driven by our digital transformation and business optimization initiatives," Chief Financial Officer Eric Levin said.
Warner Music is "confident in our long-term growth prospects, particularly as the areas of our business that have been most impacted by Covid return to normal."
Warner Music shares at last check were little changed at $29.12.
