The acquisition was announced despite a strongly worded statement Monday from Atlas Arteria's biggest shareholder IFM Investors, following confirmation of the talks. It said the deal could be potentially "dilutive to distributions" and that those concerns were shared by other major shareholders. "We are disappointed with the decision by Atlas Arteria to proceed with the acquisition of Chicago Skyway," an IFM spokesman said via text message. "As a major shareholder, we are considering our options." IFM said it could seek "an accelerated board transition by way of an EGM (extraordinary general meeting), to protect its interests as a shareholder of the company" if the deal went ahead. The acquisition is subject to regulatory approvals including consent of the city of Chicago.
