The Panel has received an application from Diamond Infraco 1 Pty Ltd, a subsidiary of IFM Global Infrastructure Fund, concerning governance arrangements related to Atlas Arteria’s Chicago Skyway investment. The application arrives as IFM pursues an off-market takeover bid for the remaining 65.52% of Atlas Arteria it does not own, having launched the offer on 27 April. IFM already holds 34.48% of the toll road operator and maintains two nominee directors on the company’s board.
Atlas Arteria’s interest in Chicago Skyway forms a key asset for investors to understand. The company owns 66.67% of the toll road concessionaire through a partnership with Ontario Teachers’ Pension Plan Board, which holds the remaining 33.33%. When Atlas Arteria acquired its stake in September 2022, it disclosed certain governance arrangements between the shareholders in what it termed Key Governance Terms, a disclosure that now faces scrutiny.
Those terms included two critical provisions: a right of first offer (ROFO) requiring either shareholder to offer its stake to the other before seeking third-party buyers, with a 180-day window to complete external sales at prices no lower than initially offered; and a put option favoring Ontario Teachers. Under the put option, Ontario Teachers can sell its 33.33% stake to Atlas Arteria at fair market value plus 7.5% if a change of control occurs at the parent company.
IFM’s application asserts that Atlas Arteria’s original disclosure failed to adequately explain how these mechanisms would operate in a change-of-control scenario, which is precisely the situation that would arise if IFM succeeded in its takeover. The application highlights a material gap in how investors were informed about potential complications arising from the Chicago Skyway governance structure during any ownership transition.
Atlas Arteria’s response demonstrates defensive intent. On 22 April, just before IFM announced the bid, the company issued a ROFO notice to Ontario Teachers regarding its 66.67% stake in Chicago Skyway, priced at acquisition-aligned levels. This move creates tactical complications for any takeover. If Ontario Teachers accepts the notice, Atlas Arteria must sell the majority stake, shrinking the asset base available to IFM. If Ontario Teachers declines, the optionality remains but introduces operational uncertainty.
For investors assessing the bid, several factors now demand close attention. The Panel’s determination on disclosure adequacy could influence how shareholders view the offer’s credibility. Ontario Teachers’ acceptance or rejection of the ROFO notice will materially affect what asset position IFM would ultimately control. The put option simultaneously presents complications, as a successful change of control could force capital consumption through a 7.5% premium buyout of Ontario Teachers’ interest. How these governance mechanisms interact with the takeover process will significantly influence the bid’s trajectory and ultimate value proposition. This announcement is price sensitive and has been flagged as material by the ASX.
