Paul Miller, chief executive officer of Questex since 2018, will take over as chief executive officer of the combined Emerald-Questex company when the Apollo-backed transaction closes in the second half of 2026. Hervé Sedky, currently president and chief executive officer of Emerald, will move to a senior adviser role at closing.
The leadership change comes as Apollo said Miller will be responsible for integrating the two businesses into a larger B2B events platform. Miller has spent more than three decades in events, information services and media, and at Questex he says he has expanded the company across hospitality, travel, healthcare, life sciences, beauty and technology.
The transaction itself remains on track for the second half of 2026, pending customary closing conditions and regulatory approvals.
Apollo said it had about $1.03 trillion in assets under management as of March 31, 2026.
Emerald describes itself as a U.S.-based B2B event organizer with a portfolio spanning trade shows, conferences, B2C showcases and an executive peer network platform. Questex says it operates live events supported by data insights and year-round digital communities. Following these announcements, the company's shares moved -0.1%, and are now trading at a price of $5.025. Check out the company's full 8-K submission here.
