With all eyes on HBO’s Harry Potter series, the J.K. Rowling franchise continues to magic up sales across its audiobook and theatrical arms.
Financial earnings published on the UK’s Companies House reveal that Pottermore Limited and HPTP Holdings remain profitable, even if they had mixed years in terms of revenue. Rowling controls both companies.
Pottermore Limited, which oversees Harry Potter audiobook adaptations and ebooks, posted record sales of £54.3M ($72.6M) in the 12 months to the end of March 2025.
This was up 11% on the previous year and may not fully reflect the revenue generated from the high-profile new Audible adaptation, which stars Hugh Laurie as Albus Dumbledore, Matthew Macfadyen as Lord Voldemort, and Keira Knightley as Professor Umbridge.

Pottermore Limited’s pre-tax profit increased 50% to £17.2M, delivering a 32% margin. “The company exceeded all target KPIs in the year,” said Neil Blair, Rowling’s agent, in a Pottermore director’s report.
HPTP Holdings, which is the parent company to theatrical productions of Harry Potter and the Cursed Child, saw its revenues drop by half in the year to the end of March.
Sales declined from £12.7M to £5.8M year-on-year, while pre-tax profits slid from £4.2M to £1M over the same period, per the Companies House filing.
“The drop in revenue was due to a combination of show closures in the prior year, the non-repeat of licence fee income and broader economic pressures impacting both audiences and the wider theatrical sector. This was offset by income from the new US Tour,” Blair said.
“In London, the popularity of the original two-part production of Harry Potter and The Cursed Child continued with the show celebrating its eighth-year anniversary during the period.”
