The Takeovers Panel has declined to make a declaration of unacceptable circumstances in response to Atlas Arteria’s challenge to Diamond Infraco’s takeover bid, effectively clearing the way for DICO to proceed with its $4.75 per security offer. The decision resolves regulatory uncertainty that had hung over the transaction since Atlas Arteria lodged its application on 6 May, though the Panel’s willingness to engage with the case suggests the bid structure raised legitimate governance questions that required addressing through modified disclosure and undertakings rather than outright rejection.
DICO, a subsidiary of IFM Global Infrastructure Fund, had designed its offer with a conditional price escalation to $5.10 per security if it achieves a 45% or greater relevant interest before the offer closes. Atlas Arteria identified a practical problem with this structure: if DICO crosses the 45% threshold late on the final day of the offer period, there may not be enough time to lodge a notice of variation under section 650D of the Corporations Act, creating legal and timing uncertainty for shareholders trying to decide whether to accept. The Panel took these concerns seriously enough to require modifications rather than dismissing them outright.
The resolution hinged on two key concessions. First, ASIC granted relief modifying section 624(2) to automatically extend the offer period by 14 days if the 45% threshold is met and the price has not already been increased to $5.10. This mechanism eliminates the timing crunch Atlas Arteria identified and gives DICO breathing room to formally increase the offer price. Second, DICO provided an undertaking not to exercise its discretion to treat late-received acceptance forms as valid if doing so would push its relevant interest to 45% or more before the price increase is formally implemented. Together, these measures addressed the Panel’s residual concerns about potential uncertainty and manipulation.
For Atlas Arteria shareholders, the decision means the offer will likely proceed without further regulatory hurdles. The Panel’s acceptance of ASIC relief and DICO’s undertaking suggests the transaction structure is workable, though the 14-day extension provision could extend the total offer period if triggered. At the application date, DICO held 34.48% of securities, meaning it needs to acquire roughly 11% more to reach the 45% threshold and trigger the higher $5.10 price. Shareholders should monitor DICO’s acceptance levels as the offer progresses to assess whether the conditional price increase appears likely to materialise.
The Panel’s decision also underscores how regulatory scrutiny can refine transaction mechanics even when the underlying offer structure is not deemed unacceptable. The case demonstrates that timing and disclosure matter as much as price in takeover regulation. Investors holding Atlas Arteria securities now face a clearer path to resolution, though the ultimate success of DICO’s bid depends on achieving sufficient acceptances at the $4.75 base price or triggering the conditional increase.
