Atlas Arteria's Rejected Takeover Bid Leads to a Chicago Skyway Sale Plan

A four-year hostile takeover saga with IFM Investors ended in board rejection, with Atlas Arteria now testing the market for its Chicago Skyway asset to unlock value instead.

Atlas Arteria became the subject of a four-year hostile takeover saga by major shareholder IFM Investors, whose tiered $4.75-to-$5.10 per share bid the board rejected as undervalued, prompting the toll road operator to test the market for a sale of its Chicago Skyway asset as an alternative way to unlock value for shareholders.

Ongoing French government intervention weighs on the stock

Pendal Group said the stock fell 7.9 percent after the French government announced that a planned reduction in the special tax on French motorways would be deferred from 2026 to 2027, describing it as the latest in a long-running pattern of French government interventions that destroy value for Atlas Arteria investors.

IFM's tiered takeover bid finally arrives

Pendal Group said the stock rose as IFM Investors announced a final and best takeover offer, coming four years after first bidding for the company, during which time the stock had dramatically underperformed the market as IFM steadily crept up the register, with the bid structured as $4.75 a share cash, a 10 percent premium to last close, increasing to $5.10 if acceptance thresholds were met. Solaris Investment Management, overweight, said the stock performed strongly, up 17.9 percent, following the formal takeover bid, with the initial offer representing an 11 percent premium and the potential increase to $5.10 representing a 19 percent premium subject to acceptance thresholds. Resolution Capital said the stock rallied late in the month after the private roughly 34 percent equity owner launched an unsolicited off-market takeover bid at A$4.75 a security in cash, rising to A$5.10 if acceptances took its stake to 45 percent or more, with shares trading above the bid price following the announcement.

The board rejects the bid and pursues a Chicago Skyway sale

Pendal Group said the stock rose 1.4 percent after Atlas Arteria released its Target's Statement rejecting IFM's takeover bid as undervalued, not a surprise since the bid did not appear to be a serious attempt to take control of the company, with Atlas Arteria beginning a process of testing the market for the sale of its Chicago Skyway asset, which it controversially bought four years earlier.

An arbitrage opportunity with low downside, high optionality

Harvest Lane Asset Management's Cummings said Atlas Arteria, a global toll road developer and operator with roads in France, Germany and the US, currently offers low downside, high optionality for investors thanks to the IFM proposal that would value shares at $5.10. Cummings said Atlas Arteria is planning to sell its Chicago Skyway asset to defend itself, which eliminates acquisition risks and could beat IFM's tiered offer, arguing there is more value to be unlocked in a deal structured to be highly appealing to hedge funds. Pendal Group said IFM's bid was reaching its end point, made unconditional with a flagged higher bid price but noted as final and expiring at the end of the week, with IFM's ownership at 38.5 percent and a high probability of falling short of control given the board still opposed the bid.

What fund managers say they are watching next is the outcome of IFM's final, unconditional bid given its 38.5 percent ownership and continued board opposition, progress on the Chicago Skyway asset sale as an alternative value-unlocking strategy, whether French government tax deferrals continue weighing on the underlying business, and whether the M&A arbitrage opportunity Harvest Lane describes plays out favourably.
