A$1.1 billion Convertible Notes Offering

Page 1 of 34 NOT FOR DISTRIBUTION OR RELEASE IN THE UNITED STATES ASX Release 9 September 2026 A$1.1 billion Convertible Notes Offering NEXTDC Limited (ASX: NXT) (“NEXTDC” or the “Company”) today announces the launch of an offering (the “Offering”) of A$1,100 million of fixed coupon subordinated convertible notes due 2031 (the “Convertible Notes”). The Convertible Notes are convertible into fully paid ordinary shares of NEXTDC (the “Ordinary Shares”). The Offering will strengthen NEXTDC’s liquidity and provide committed funding for its development pipeline, while preserving flexibility to support further customer-led growth. The Convertible Notes are expected to carry an indicative cash coupon of approximately 1.25% to 1.75% per annum, subject to the outcome of the bookbuild. The indicative cash coupon is materially below the weighted average cash interest cost of NEXTDC’s existing senior debt facilities and below the cash cost of comparable subordinated debt alternatives. The initial conversion price of the Convertible Notes (the “Initial Conversion Price”) will be set at a premium of 32.5% to 37.5% to the reference share price described below (the “Reference Share Price”), and will be subject to the outcome of the bookbuild. NEXTDC also intends to enter into the Capped Call Transactions described below, with an indicative cap price of 70% over the Reference Share Price, which are intended to increase the effective conversion price, up to the cap price. The Offering is consistent with NEXTDC’s long-term strategy to diversify funding sources through accessing differentiated global sources of capital, to enhance financial flexibility and maintain a strong liquidity position and balance sheet. Craig Scroggie, NEXTDC Chief Executive Officer and Managing Director, said: “We are proactively enhancing balance sheet flexibility with efficient capital and continuing to deliver on our capital strategy. The convertible structure funds the next phase of our development pipeline at a lower cash coupon than senior debt and the capped call transactions effectively raise the conversion price and therefore reduce the economic cost of dilution that would otherwise occur. The Offering preserves our senior debt capacity and our balance sheet flexibility to meet the continued growth in customer demand for the capacity NEXTDC is building.” The
