NEXTDC Raises A$1.1B in Convertible Notes — Its Third Capital Raise in Four Months

NEXTDC (ASX: NXT), Australia’s largest listed colocation operator, priced A$1.1 billion of subordinated convertible notes on 9 September 2026 — its third capital raise in a little over four months — to help fund a fiscal 2027 capital expenditure plan of A$5.25-5.75 billion, 55-70% above the prior year, as it builds out AI-ready capacity in Australia and its new Southeast Asian footprint.

What is known

Per the company’s ASX filing, as reported by The Motley Fool Australia, TechNode Global and TheNextWeb, the notes are due 17 September 2031, with holders able to exercise a put option in September 2029. NEXTDC guided an indicative coupon of 1.25-1.75% per year and an initial conversion price set at a 32.5-37.5% premium above a reference share price, alongside capped-call transactions capped around 70% above that reference. Net proceeds, after the capped-call costs, are expected to be roughly A$1.006 billion. The notes are aimed at institutional investors and are set to list on the Vienna Multilateral Trading Facility rather than the ASX itself.

This is the third time NEXTDC has tapped capital markets since April 2026: an A$2.2 billion capital plan anchored by a fully underwritten A$1.5 billion equity entitlement offer and hybrid commitments from La Caisse, followed in May by A$1.8 billion of new senior debt facilities from a syndicate of domestic and international banks. Combined with the September notes, NEXTDC has lined up roughly A$5.1 billion across the three raises. TheNextWeb reports the company expects to spend A$5.25-5.75 billion in FY2027 alone — company guidance we have not seen independently corroborated by a source outside NEXTDC’s own disclosures.

What this means for the buyer of power

NEXTDC is not a name on a spreadsheet for us — three of its facilities are in our global catalog: M2 Melbourne (120+ MW, Uptime Tier IV constructed-facility certified), S3 Sydney (80 MW, an AUD 1 billion build), and NEXTDC KL1 in Kuala Lumpur, which went live on 14 May 2026 with 65 MW of design capacity as the company’s first Southeast Asian site. A capex plan this size, if it lands as guided, points to meaningfully more Tier IV-class supply reaching the Australian and Malaysian markets over the next 12-18 months — the kind of new capacity that typically caps how fast wholesale rack rates can climb, even as AI-driven demand keeps colocation markets tight elsewhere in the region. We don’t yet publish a wholesale $/kW benchmark for Australia in our colocation price index, though we do track Australian commercial electricity tariffs in our power data, a direct input into any operator’s cost base.

What we don’t know yet

NEXTDC’s own release has not surfaced in our search with a public breakdown of how the FY2027 capex splits between its existing Australian sites and the newer Kuala Lumpur expansion, nor whether further Southeast Asian sites are already funded by this raise or would require a fourth capital round. The notes are also still subject to final settlement, expected around 17 September 2026, a few days after pricing.
