NEXTDC Limited (ASX: NXT) shares jumped 7.74% to close at A$14.06 on Tuesday.
The rise followed an update from the data centre operator showing another increase in customer contracts. Investors welcomed the news because it offered more evidence that demand for NEXTDC’s infrastructure remains strong as artificial intelligence and cloud computing increase the need for data storage and processing capacity.
What Did NEXTDC Announce?
NEXTDC said its pro forma contracted utilisation reached 740 megawatts as at 30 June 2026. That was an increase of 73MW, or 11%, from its previous update on 20 April.
Contracted utilisation is the amount of data centre capacity customers have committed to use. A rising figure shows customers are signing agreements for more capacity.
NEXTDC’s pro forma forward order book also increased to 565MW. This represents the difference between its 740MW of contracted utilisation and the 175MW already being billed at the end of June.
The company expects this order book to convert gradually into billings, revenue and EBITDA between FY26 and FY30. NEXTDC also confirmed that its FY26 net revenue, underlying EBITDA and capital expenditure guidance remained unchanged.
Why Did NEXTDC Shares Rise?
The immediate catalyst was the latest round of customer contract wins. The update showed that demand has continued to grow since NEXTDC’s major April announcement.
In April, the company reported that pro forma contracted utilisation had risen by about 250MW, or 60%, to 667MW. Its forward order book increased by 83% to 544MW.
The latest rise to 740MW suggests the April increase was not simply a one-off event. It gives investors greater confidence that NEXTDC is continuing to attract customers while expanding its data centre network.
AI remains part of the wider investment story. Artificial intelligence systems require significant computing power, secure facilities, cooling and reliable electricity. Data centre operators such as NEXTDC provide the physical infrastructure needed to support these workloads.
However, the company did not identify the customers behind the latest contracts or say that all the new capacity was directly linked to AI. New contracts caused the immediate market reaction, while AI and cloud growth supported the broader optimism.
How Is NEXTDC Funding Its Expansion?
NEXTDC is arranging substantial funding to build the capacity required under its contracts.
In April, the company announced a fully underwritten entitlement offer to raise approximately A$1.5 billion and increased its hybrid securities offer to A$1.7 billion.
On 10 July, NEXTDC upsized its new senior debt facilities from A$1.8 billion to A$2.3 billion. Once the facilities reach financial close, total available senior debt facilities are expected to rise from A$6.4 billion to A$8.7 billion.
The proceeds will mainly support spending linked to recent contracts, ongoing data centre developments and general corporate purposes.
What Should Investors Watch Next?
NEXTDC’s forward order book provides a path towards future revenue growth. The challenge is turning contracted demand into operating capacity and cash earnings.
Investors should watch construction timelines, capital spending, debt levels and how quickly the new capacity starts generating revenue.
Tuesday’s rally shows that confidence in NEXTDC’s growth story has improved. The next test will be whether the company can deliver new capacity on time and convert its record order book into profitable long-term growth.
