Fixer Upper and other Magnolia Network shows coming to HBO Max in September (EXCLUSIVE)

Chip and Joanna Gaines’ Magnolia Network lineup, together with all 5 seasons of HGTV’s “Fixer Upper,” will start streaming on HBO Max in September, Variety has discovered exclusively.

According to a WarnerMedia source, "select" titles from the Magnolia Network will come to the streamer on Friday, Sept. 30, as part of a page featuring Gaines' "curated" content, including "Fixer Upper: Welcome Home," "Magnolia's Table with Joanna Gaines" and "The Lost Kitchen," among other series. The former HGTV superstars launched their Magnolia linear and streaming channel in partnership with Discovery last year, before Discovery merged with WarnerMedia.

Industry reassets say a brand new series, "Fixer Upper: The Castle," which facilities at the Gaines' overhauling in their 100-year-vintage fortress in Waco, Texas, will optimum Oct. 14 on HBO Max with the Linear Magnolia Network and Discovery+.

More Magnolia Network content will be added to HBO Max over time, but will also be available on Discovery+, which costs $4.99 per month with ads, compared to HBO Max's $9.99 ad-supported plan, WBD sources say.

The news comes ahead of Warner Bros. Discovery's Q2 earnings report and presentation later today, which is expected during CEO David Zaslav and co. Reveal more about the future of HBO Max and Discovery+ — which will converge on one platform at a time — and plans for the rest of the company.

The Magnolia Network first launched as an app within Discovery+ last July, and a linear channel rebranded from Discovery's DIY network went live in January.

Variety exclusively reported in April that before Discovery's acquisition of WarnerMedia was completed and rebranded to Warner Bros. Discovery, it was decided that oversight of the Magnolia Network, a joint venture between Gaines and Discovery, would go under the team at HBO.

In this new structure, Magnolia President Alison Page now reports directly to Casey Bloys, head of HBO and HBO Max content. Bloys is one of the few top WarnerMedia execs still standing after the mass exodus that first began before the Discovery-WarnerMedia merger and continues as Zaslav gradually unveils his new leadership team and structure.

Warner Bros. Discovery chairman and US network group Kathleen Finch is being replaced by Kathleen Finch, chief content officer, from HBO and the "Fixer Upper" star to lead the lifestyle brand, a significant sign of integration between the two companies. The couple has long been deeply tied to Legacy Discovery's identity because of Gaines' origins as an HGTV icon.
