ISV Information Services Corporation

Information Services Corporation (TSX:ISV) (“ISC” or the “Company”) is pleased to announce that through its wholly owned subsidiary, Reamined Systems Inc. (“Reamined”), the Company and His Majesty the King in right of Ontario as represented by the Minister of Finance (the “Ministry”) have entered into an amended and restated License and Information Technology Services Agreement (the “A&R OPTA Agreement” or the “Agreement”) to continue the management and operation of the Online Property Tax Analysis (“OPTA”) system for the province of Ontario, until March 31, 2028 — with two additional options for one-year renewals.

Acquired by ISC in 2022, Reamined is a recognized leader in property tax mitigation support for municipal property tax administrators and has been providing these services to the Ministry since the creation of the OPTA system.

The OPTA System was built by Reamined on behalf of the Government of Ontario in 1998 as a comprehensive, centralized budgetary planning tool and property tax accounting system for Ontario municipalities, the unincorporated territories and government ministries.

“The professionals at Reamined are property tax experts that contribute a wealth of knowledge and have a highly regarded track-record in delivering property tax systems that work,” says ISC President and CEO, Shawn Peters. “Reamined is a natural extension of ISC’s Registry Operations segment and expands ISC’s role as a trusted service provider to other jurisdictions. Together with Reamined, we are proud to be working alongside the Ministry on behalf of the people of Ontario, ensuring their property tax system continues to be operated and managed successfully for years to come.”

Without the renewal agreed to in the A&R OPTA Agreement, the prior agreement between Reamined and the Ministry would have expired in March 2025. The early renewal of the Agreement ensures consistency and continued efficiency of these services by their current trusted provider.
