08:45 AM EDT, 04/08/2025 (MT Newswires) -- Privately-held Plantro on Tuesday extended to April 28 from April 11 the offer period for its bid to buy up to 2.8 million Class A shares, or 15%, of Information Services (ISC.TO) at an unchanged offer price of $27.25 cash per share.

Plantro, which is controlled by Matthew Proud, the former chief executive of Dye & Durham, said it "was surprised and disappointed at the aggressive and hyperbolic posture adopted by ISC's board of directors." Plantro also noted that the company has not responded to requests to meet.

This comes after ISC earlier on Tuesday said its unit ESC Corporate Services will continue as a service provider for the Ontario Business Registry for an initial two-year period, with three one-year options that the province may exercise at its discretion. The prior agreement expired at the end of January.

Shares of the company closed down 0.1% to $25.97 on Monday on the Toronto Stock Exchange.
