  • • The Clarion sale represents a significant portfolio restructuring by Blackstone as it reallocates capital from events infrastructure
Summary
Blackstone has agreed to divest Clarion, its B2B events business, at a $3 billion enterprise valuation. Clarion is a UK-headquartered operator of more than 100 B2B brands and platforms, with particular strength concentrated in its top-tier franchises. The company's ten largest category-focused event franchises account for approximately two-thirds of Clarion's total revenues, highlighting the strategic importance of these marquee platforms to the overall business model.

The transaction represents Blackstone's exit from the events infrastructure sector following a period of ownership. Clarion's diversified portfolio spans multiple industry verticals through its extensive B2B brand network, though the revenue concentration in leading franchises underscores both the appeal and risk profile of the asset.

In parallel, Eurazeo is advancing its alternative investment strategy with a new position in water efficiency through Miya Water. The move reflects Eurazeo's strategic expansion into sustainability-focused infrastructure and environmental technology, diversifying its investment mandate beyond traditional private equity and real estate holdings.
