ISC Information Services Corporation

Information Services Corporation (TSX: ISC) (“ISC” or the “Company”) today reiterated its recommendation to shareholders to Reject and Do Not Tender their shares to the amended tender offer (the “Mini-tender”) from offshore entity Plantro Ltd. (“Plantro”). The recommendation comes after the Special Committee of directors (the “Special Committee”) appointed by ISC’s Board of Directors (the “Board”), reviewed the Mini-tender, with the benefit of advice from external advisors.

Plantro was compelled to change its Mini-tender following regulatory and media scrutiny. The Mini-tender is self-serving, undervalues ISC and is not in the best interests of ISC shareholders. As of this news release, two days after Plantro’s news release announcing amendments to its coercive Mini-tender, ISC and its shareholders are yet to see a full copy of the revised offer.

ISC is Delivering Long-Term Value – DO NOT TENDER

ISC has a history of delivering long-term value to shareholders. Successful execution of its growth strategy has delivered total returns to ISC shareholders of 2091 percent since its IPO, significantly outperforming the S&P/TSX SmallCap Index over the same period.

In 2024, the Company announced its plan for its next stage of growth, which is intended to double the size of the Company on a revenue and adjusted EBITDA basis by 2028, based on its actual 2023 revenue and adjusted EBITDA.

By 2028, ISC is expected to generate over $425 million and $145 million in revenue and adjusted EBITDA, respectively, which represents an annualized mid-teens growth rate for revenue and adjusted EBITDA. Achieving these high-conviction targets would represent an impressive, annualized growth in revenues and adjusted EBITDA and translate into a meaningfully higher future share price and strong, compelling returns for shareholders. ISC has made good progress on its plan, as evidenced by its record financial performance in 2024. See the “Non-IFRS Performance Measures” Section below.

Several sophisticated institutional investors have maintained their position in the Company since the IPO in July 2013, while others have increased their positions in ISC in recent years, a clear vote of confidence in ISC’s strategy, strong and stable leadership, and long-term potential. The Company’s trading liquidity reflects this committed shareholder base.

ISC has built a diversified and resilient business with a clear growth strategy, backed by a strong balance sheet, excellent access to capital and a robust M&A pipeline to add further value. This reinforces the Special Committee’s recommendation that ISC’s long-term value significantly exceeds the unsolicited and highly undervalued Mini-tender’s $27.25 per share offer. Independent analysts concur on the material upside, with a current consensus price target that is materially higher.

The Company’s strategic strengths as acknowledged by Plantro, are precisely why this is not the time to tender. In a volatile global market, selling a growing and resilient business like ISC at a discount does not serve shareholders’ best interests.

Plantro’s Amended Offer

Plantro amended their Mini-tender following ISC’s press release dated April 6, 2025, and a Globe and Mail report dated April 7, 2025, both of which detailed the coercive elements in Plantro’s Mini-tender.

Plantro also faced regulatory scrutiny from the Financial and Consumer Affairs Authority of Saskatchewan (“FCAA”) and the Ontario Securities Commission (“OSC”) for tactics that have previously been identified by regulators as being inconsistent with principles of market integrity.

Despite the recently announced amendments, the Mini-tender offer remains coercive, unfair to shareholders, and contrary to the public interest.

Key Concerns Remain Unaddressed

Plantro’s revised Mini-tender does nothing to change the facts: it’s opportunistic, lacks transparency and serves its own interests, not those of ISC shareholders.

• The Mini-tender significantly undervalues the Company at $27.25 per share and seeks voting control without fair compensation to ISC shareholders.
• The Mini-tender offer remains coercive, unfair to shareholders, and contrary to the public interest.
• As of this news release, two days after Plantro’s press release announcing amendments to its coercive Mini-tender, ISC and its shareholders are yet to see a full copy of the revised offer.
• Given Plantro’s stated desire to “refresh” the Board, shareholders should expect an attempt to replace ISC directors using proxies gathered through the Mini-tender, even though Plantro has not disclosed this intention in its Mini-tender materials.

Non-IFRS Performance Measures

Included within this news release is reference to adjusted EBITDA, which is not a recognized measure under International Financial Reporting Standards (“IFRS”) and does not have a standardized meaning prescribed by IFRS. This measure, which is reconciled below, is reviewed regularly by management and the Board of Directors in assessing our performance and making decisions regarding the ongoing operations of our business and its ability to generate returns. These measures may also be used by external parties in decision making related to ISC’s performance. They are not recognized measures under IFRS and do not have a standardized meaning under IFRS, so may not be reliable ways to compare us to other companies.
