HBO Family, ThrillerMax and Other Multiplex Channels to Be Shut Down by Warner Bros. Discovery

Warner Bros. Discovery will shut down HBO Family and Cinemax multiplex channels ThrillerMax, MovieMax, and OuterMax on August 15, 2025, as part of a broader strategy to reduce its linear channel offerings amid declining viewership and a shift to streaming platforms like HBO Max. This decision aligns with WBD's larger plan to cut the company in half, spinning off linear basic cable networks into a new entity, though HBO is not part of this spinoff. The move reflects the challenges faced by traditional premium cable channels in retaining audiences in the face of growing streaming competition.

Analysis

Warner Bros. Discovery (WBD) will cease operations for HBO Family and Cinemax multiplex channels ThrillerMax, MovieMax, and OuterMax on August 15, 2025. This action is part of a wider strategy to reduce its linear multiplex channel offerings, driven by sustained viewership declines in traditional premium cable as audiences shift towards streaming services like HBO Max, where the majority of HBO's original series viewership now resides. The channel closures are contextualized by WBD's recently announced plan to divide the company, spinning off its linear basic cable networks into a separate entity, though HBO is slated to remain with the core WBD. While the affected multiplex channels primarily aired reruns, HBO Family had become the repository for HBO's children's programming. WBD will, however, maintain other HBO and Cinemax multiplex channels, indicating a selective rather than complete abandonment of this model.

Key Decisions for Investors

• Investors should view these channel shutdowns as a component of WBD's broader efforts to streamline operations and adapt to secular shifts in media consumption, focusing on the health of its core streaming assets.
• Closely track the execution of WBD's larger restructuring, including the planned company split, and assess its impact on the valuation and strategic direction of the post-spinoff WBD entity.
• Evaluate the subscriber trends and monetization strategies for HBO Max, as its performance is paramount to WBD's long-term growth amidst the decline of linear television.
