CisionCision, whose private equity parent made a splash by acquiring Vocus and Gorkana, is reportedly among bidders for PR Newswire.

Reuters reports that UBM's planned sale of the profitable news dissemination service, aimed at around $700M, has attracted a bid from Cision.

A deal for PRN would likely be the capstone of a major consolidation in the PR services sector following the Cision-Vocus-Gorkana tie-up.

UBM wants to focus on its core events business, especially in the wake of its nearly $1B acquisition of Advanstar Communications.

PR Newswire had $302M in revenues last year and operating profit of nearly $70M.

GTCR is Cision's private equity owner.
