First Supplementary Bidder's Statement

• ASIC relief modifies section 624(2) of the Corporations Act
• Offer period extended if Bidder's interest reaches 45% or more
• Supplementary statement supplements initial Bidder's Statement

Diamond Infraco 1 Pty Ltd, a subsidiary of IFM Global Infrastructure Fund, issued a first supplementary bidder's statement on 20 May 2026 in relation to its takeover offer for Atlas Arteria. This supplementary statement supplements the initial Bidder's Statement dated 27 April 2026. The Australian Securities and Investments Commission (ASIC) has granted relief to modify section 624(2) of the Corporations Act, which extends the offer period by 14 days if the Bidder's relevant interest in Atlas Arteria Securities increases to 45% or more within the last 7 days of the offer period, provided the offer price has not already been increased to $5.10 per Atlas Arteria Security.

The supplementary bidder's statement provides clarity on the conditions under which the offer period may be extended, enhancing the potential for a successful takeover bid.
