PR software provider Cision has postponed its annual meeting originally slated for April 9 as a takeover offer from a Chicago investment firm runs through March 27.

Cision said its annual general meeting will now be held on May 27, two months after the acceptance period for the bid from GTCR Investment lapses.

The PR services company's board has expressed interest in the cash offer, which is more than a 50 percent premium on Cision's Stockholm-traded shares. A resolution on the offer has been expected around April 7.

Cision has spent the last few years transitioning to a "digital first" strategy as it moved away from dependence on print and broadcast monitoring. GTCR, in making its pitch last month, said it believes technology will become a more critical component of the "PR workflow."

Cision saw fourth quarter 2013 revenue decline 11.3% to around $33M.
