Satz takes on his role with immediate effect, having most recently served as senior vice president of government relations and development for Caesars Entertainment from 2002 to 2019.
Prior to this, he spent 16 years at US law firm Saiber Schlesinger Satz Goldstein LLC, where he had a particular focus on the gambling industry.
“David has unrivalled regulatory and legislative expertise in the all-important US gaming market,” GVC chairman Barry Gibson said.
“His knowledge and insight will be hugely additive in helping us to achieve our ambition of being the leading operator in the US through BetMGM, our fast-growing joint venture with MGM Resorts.”
Hoskin, who has been at GVC since 2005 and is currently group director of legal, regulatory and secretariat, will begin his new role and take his place on the GVC board from 1 January next year.
Before joining PartyGaming, Hoskin headed the investment company secretariat at Aberdeen Asset Management.
“Robert has made an outstanding contribution to GVC in his 15 years at the Group, and his promotion is richly deserved,” Gibson said.
“The fact that regulation, legal and governance are now represented at board level will give us even greater oversight of these critically important areas, all of which are central to our long-term growth plans.”
The double appointment comes after GVC last week announced that it had been able to retain its position in the FTSE4Good Index Series, and also secured independent verification of its carbon emissions data from the Carbon Trust.
Earlier this month, GVC also raised its earnings guidance for 2020 after seeing a 12% year-on-year rise in net gaming revenue for the third quarter of 2020, with full-year earnings are now set to reach £50m.
