Toll road operator Atlas Arteria has rejected an increased cash takeover bid from its largest shareholder, , arguing that the A$7.4bn (€4.5bn) offer materially undervalues the company and its assets across France, Germany and the US.

IFM, which holds a 35.68% stake in Atlas Arteria, has made a seventh bid of A$5.10 per share through its investment vehicle, Diamond Infraco. This is an increase from the A$4.75 per security cash offer made in April.

IFM said the offer price of A$5.10 per Atlas Arteria security is β€œbest and final, and will not be increased in the absence of a competing proposal” for Atlas Arteria.

In response, Atlas Arteria urged securityholders reject the proposal, branding it β€œtoo low” and arguing it fails to pay an β€œappropriate premium for control”.

Atlas Arteria also noted media speculation of a potential 10% β€œon-market raid” by IFM, and warned that if this raid involves using borrowed shares to short-sell into the offer, Atlas Arteria is ready to take the matter to the Takeovers Panel.

IFM’s offer will not close until 25 June 2026 unless extended.

Atlas Arteria owns a 30.8% interest in the 2,424km motorway network located in France and a 100% of the Warnow Tunnel in the north-east city of Rostock in Germany. Its assets in the US include a 66.67% interest in the Chicago Skyway, in Chicago and has 100% of the economic interest in the Dulles Greenway, a 22km toll road in Virginia.
