Informa has confirmed plans to purchase event organizer Clarion for an enterprise value of £2.24 billion, or $2.96 billion. This agreement follows an acquisition pause for Informa and marks the end of months of work to secure the deal.
Why it matters
The deal signals a return to M&A activity for Informa as it absorbs a major player in the international trade exhibition sector. Integrating Clarion brings the Defence and Security Equipment International event series under Informa’s broader portfolio.
The acquisition represents an enterprise value of £2.24 billion, which converts to approximately $2.96 billion. This deal follows several months of negotiations after the possibility of a transaction first emerged in the summer of 2026.
The players
Informa
Informa is a global publishing, business intelligence, and exhibitions group headquartered in London.
Clarion
Clarion is a leading international organizer of trade shows, conferences, and security-focused exhibitions.
The details
Clarion is recognized for organizing the Defence and Security Equipment International series, which hosts events in cities and regions including London, Japan, and Germany. The purchase allows Informa to expand its reach in the high-stakes exhibition market, notably adding the Apex Defense event in Washington to its operations.
Timeline
