ASIC has granted relief that fundamentally alters the dynamics of the IFM Global Infrastructure Fund’s takeover offer for Atlas Arteria Limited. Under this relief, if Diamond Infraco 1 Pty Ltd accumulates a relevant interest of 45 percent or more during the final seven days of the offer period, and the offer price has not already been increased to $5.10 per security, the offer period automatically extends for a further 14 days. This mechanism gives shareholders additional time to respond to any material change in the bidder’s position during the crucial closing stages.

The emergence of this first supplementary statement barely three weeks into the takeover process indicates that the regulatory framework required tailored treatment. ASIC’s grant of relief addresses specific timing constraints and disclosure obligations that could otherwise compress shareholders’ decision-making window. The automatic extension provision represents ASIC’s conclusion that standard takeover code provisions were insufficient to properly protect shareholder interests in this particular transaction.

The specific thresholds embedded in the relief warrant investor attention. The 45 percent relevant interest threshold marks a point where the bidder would control nearly half of Atlas Arteria, a substantial concentration of ownership. The $5.10 per security price point functions as an alternative lever, whereby the bidder could circumvent the automatic extension simply by raising its offer to that level before the final week. These dual conditions create distinct paths forward, with meaningful implications for the offer’s conclusion.

For shareholders, the practical impact is tangible. An extended offer period provides additional time to evaluate information, seek clarification, and reconsider participation in the merged entity. The mechanism functions as a safeguard against late-stage accumulation of shares without triggering the pricing adjustments or disclosure obligations that normally accompany significant changes in bidder position. The extended timeline also creates opportunity for new developments or announcements that could influence shareholder decisions.

Investors should monitor whether the bidder’s relevant interest approaches the 45 percent threshold and track any announcements regarding a price increase to $5.10. The interaction between these conditions will determine whether automatic extension occurs. The bidder’s accumulated position as of 20 May, and how it evolves through the remainder of the offer period, will signal its strategic intentions. This announcement is price sensitive and has been flagged as material by the ASX.
