A$1.1 billion convertible notes offering settles, bolstering NEXTDC’s infrastructure war chest
NEXTDC Limited (ASX: NXT) confirmed on 18 September 2026 that its offering of A$1,100 million in subordinated convertible notes due 2031 settled on 17 September 2026. The notes were issued on that date and provide the company with significant capital to fund its data centre expansion pipeline without immediately diluting existing shareholders.
The Convertible Notes are not quoted on the ASX. Instead, they have been approved for listing and trading on the Vienna Multilateral Trading Facility from 18 September 2026, a specialist debt listing venue operated by the Vienna Stock Exchange.

Key terms of the A$1.1 billion offering
The offering carries a low cost of capital relative to its scale, with the 1.75% per annum interest rate reflecting the company’s standing in the institutional debt market. Interest is paid semi-annually, and the notes are convertible into fully paid ordinary shares of NEXTDC in accordance with their terms and conditions.

Understanding the three transactions behind the offering
This announcement encompasses three distinct but related transactions. Each operates differently and carries separate implications for shareholders.
-
The Offering: NEXTDC raised A$1,100 million through subordinated convertible notes due 2031. These are debt instruments that pay fixed interest and may be converted into ordinary shares. As subordinated notes, they sit below senior debt in the capital structure, meaning senior creditors are repaid first in the event of a winding up.
-
The Capped Call Transactions: Alongside the offering, NEXTDC entered into cash-settled capped call transactions. These are hedging instruments designed to manage potential dilution to existing shareholders if the notes are ultimately converted into shares. NEXTDC paid the premium for these transactions at settlement. They do not involve the issuance of new shares.
-
The Delta Placement: This was a placement of existing ordinary shares conducted by the Sole Global Coordinator. It settled on 14 September 2026. NEXTDC issued no new ordinary shares and received no proceeds under the Delta Placement.
The capped call transactions matter to investors because they limit the share price dilution effect if noteholders elect to convert. The Vienna MTF listing provides a regulated trading venue for the notes as debt instruments, entirely separate from NEXTDC’s ASX equity listing.
What this means for NEXTDC’s growth ambitions
NEXTDC is an S&P/ASX 100-listed company and positions itself as Asia’s most innovative Data Centre-as-a-Service provider. The company operates Australia’s only network of Uptime Institute Tier IV certified facilities and is one of the first data centre operators in the Southern Hemisphere to achieve Tier IV Gold certification for Operational Sustainability.
An A$1.1 billion raise of this nature provides material balance sheet capacity for a capital-intensive business. Data centre infrastructure requires substantial upfront investment in land, power infrastructure, cooling systems, and connectivity — expenditures that must be committed well ahead of revenue generation.
NEXTDC’s senior debt facilities were already being expanded in May 2026, when the company secured credit-approved commitment letters for A$1.8 billion from a syndicate of eight major banks, lifting estimated pro forma liquidity toward A$8.4 billion ahead of a July 2026 Financial Close.
The timing aligns with surging global demand for data centre capacity driven by artificial intelligence workloads and the continued migration of enterprise and government systems to cloud platforms. NEXTDC’s ability to access institutional debt markets at a 1.75% coupon rate reflects the strength of that demand backdrop and the company’s credit profile.
The company’s sustainability credentials add a further dimension to the institutional investment case. NEXTDC’s corporate operations are certified carbon neutral under the Australian Government’s Climate Active Carbon Neutral Standard, and its Tier IV Gold operational sustainability certification positions it within an ESG-aligned infrastructure category that continues to attract institutional capital flows.
