NEXTDC (ASX:NXT) entered FY27 after its largest contracting year to date, with contracted utilisation reaching 740.1 megawatts at 30 June 2026 compared with 244.8 megawatts a year earlier. Billing utilisation was much lower at 175.0 megawatts, meaning the company's next phase is centred on converting a large signed order book into operating capacity and revenue. That process requires substantial construction spending, with FY27 Capital Expenditure guided to A$5.3 billion to A$5.8 billion.

NEXTDC (ASX:NXT) develops and operates data centres across Australia and a growing number of international markets. Its customers include enterprises, governments, cloud providers and hyperscale technology companies. Revenue is generated from providing data centre space, power, cooling and connectivity, while future growth depends on how quickly contracted capacity is built, energised and brought into service.

Contracted capacity expanded sharply

Contracted utilisation reached 740.1 megawatts by the end of FY26, roughly three times the 244.8 megawatts reported a year earlier. The forward order book, representing contracted capacity that had not yet started billing, stood at 565.1 megawatts.

This distinction is important because signed capacity does not contribute fully to revenue until infrastructure is built and customers begin using it. The size of the forward order book therefore provides revenue visibility, but it also creates a substantial delivery obligation.

Billing utilisation remains much lower than contracted utilisation

Billing utilisation was 175.0 megawatts at 30 June 2026, significantly below the contracted total. The gap reflects capacity that is signed but still under development or awaiting customer commencement.

NEXTDC expects approximately 197 megawatts of additional contracted capacity to convert to billing during FY27. The timing of those conversions will be one of the most important drivers of revenue and EBITDA growth because each megawatt only begins generating recurring income once the corresponding Facility and customer deployment are operational.

FY26 revenue increased

For FY26, NEXTDC reported net revenue of A$405.0 million, up 16%, while underlying EBITDA increased 15% to A$248.8 million. Statutory net profit after tax was A$82.1 million, compared with a loss of A$60.5 million in FY25.

The improvement reflects higher utilisation and continued expansion of the operating portfolio. However, the much larger contracted pipeline means the current Earnings base represents only part of the capacity that has already been sold.

FY27 guidance points to a step-up in earnings

NEXTDC has guided to FY27 net revenue of A$615 million to A$640 million and underlying EBITDA of A$385 million to A$410 million. Both ranges imply growth of more than 50% from FY26 levels.

The guidance depends on planned capacity becoming operational on schedule. Construction delays, power connection issues or slower customer commencement could affect how much of the forward order book contributes to FY27 results. The guidance therefore places considerable importance on project execution.

Hyperscale and AI Demand are driving contracting

Around 95% of recent demand has been attributed to hyperscale and artificial intelligence customers. These customers typically require much larger capacity blocks than traditional enterprise clients, which explains the rapid increase in contracted megawatts.

Large hyperscale agreements can provide long-term revenue visibility, but they also increase customer concentration. If a small number of customers account for a large share of future capacity, changes to their deployment schedules can have a material effect on construction and earnings timing.

Revenue per megawatt may decline as mix changes

Revenue per megawatt has been indicated at around A$3.9 million compared with approximately A$4.3 million previously. This is consistent with a shift towards larger hyperscale contracts, where customers commit to more capacity but may receive lower pricing per megawatt.

The lower unit revenue does not necessarily imply weaker Economics if scale, utilisation and operating efficiency improve. The key measure will be whether the larger contracted volumes generate sufficient EBITDA and cash returns after the cost of building new facilities.

Built capacity remains well below contracted demand

NEXTDC had built capacity of approximately 288 megawatts at the end of FY26, meaning a large proportion of signed capacity still requires physical construction.

This mismatch between contracted and built capacity is central to the FY27 Investment cycle. The company needs to add data halls, electrical systems, cooling infrastructure and power connections before much of the order book can begin billing.

Capital expenditure is set to rise substantially

FY27 capital expenditure is guided to approximately A$5.3 billion to A$5.8 billion. This compares with around A$3.4 billion in FY26.

The increase reflects simultaneous development across multiple data centre projects. Capital is being deployed before the full revenue contribution is realised, which means free Cash Flow can remain under pressure even while earnings rise.

The size of the programme also increases the importance of cost control, construction scheduling and access to equipment and skilled labour.

Funding has expanded to support the build-out

NEXTDC has arranged a substantial funding package across debt, hybrid securities and equity. The available structure includes senior debt, subordinated notes, hybrid capital and Equity funding intended to support the development pipeline.

Net Debt was approximately A$751 million, with gearing around 11%. The company also had no major debt maturities before December 2029, providing some duration as it moves through the current construction programme.

Funding capacity is therefore substantial, but the amount of capital required means Leverage and interest expense will need to be monitored as facilities are progressively drawn.

Interest-rate risk is partly managed

NEXTDC has indicated that its debt exposure is hedged against interest-rate movements. This reduces the risk that a sudden increase in market rates directly raises financing costs on the hedged portion.

However, hedging does not remove funding risk entirely. Higher average debt levels can still increase total interest expense, while refinancing conditions and access to capital remain relevant as the development programme expands.

Development pipeline extends across multiple markets

NEXTDC has approximately 537 megawatts under construction and a land bank exceeding 3,000 megawatts. Its development footprint includes projects in Melbourne, Sydney, Kuala Lumpur, Tokyo and Auckland.

This geographic spread provides multiple growth Options but also introduces execution complexity. Each market has different power availability, construction conditions, regulatory requirements and customer demand patterns.

Sydney S4 is one of the near-term projects

Construction has begun on the S4 data centre in Sydney, with completion expected around mid-2027.

Projects such as S4 are important because they represent the physical infrastructure required to convert signed customer demand into billing capacity. Completion timing, power commissioning and customer fit-out all affect when revenue starts.

Power availability remains a critical constraint

Data centres require very large and reliable power connections, making electricity infrastructure one of the most important constraints on expansion.

Even when land and customer contracts are secured, delays in grid connections can postpone facility commissioning. Power availability can therefore determine how quickly contracted capacity becomes revenue-generating capacity.

This is particularly important for hyperscale and AI workloads, which can require substantially more power than traditional enterprise computing.

Equipment and labour remain execution risks

Data centre construction depends on electrical equipment, cooling systems, backup power infrastructure and specialised labour. Supply-chain delays in transformers, switchgear or other critical equipment can push back completion dates.

Labour availability can also affect project schedules, particularly when several facilities are being built at the same time. Given the scale of FY27 capital expenditure, coordination across multiple projects will be important.

Customer concentration is increasing

The move towards hyperscale and AI customers means individual contracts are becoming larger. This creates efficiency because a single deal can Fill significant capacity, but it also means a smaller number of customers can account for a larger portion of future revenue.

If one large customer changes its deployment schedule, the impact may be more material than it would have been under a more fragmented enterprise customer base. Contract strength reduces cancellation risk, but timing risk still remains relevant.

The forward order book is the key earnings bridge

The 565.1 megawatt forward order book represents contracted demand that has not yet started billing. Converting this Backlog is the main bridge between FY26 earnings and the much larger FY27 guidance.

The pace of conversion matters more than the headline contracted number alone. If planned megawatts move into service on schedule, revenue and EBITDA should rise materially. If projects are delayed, earnings recognition will move further out even though the contracts remain in place.

No Dividend keeps capital focused on growth

NEXTDC did not declare a dividend, reflecting the capital-intensive stage of its development programme.

Cash is being directed towards new data centre capacity rather than distributions. Given the scale of current construction commitments, capital allocation remains focused on funding growth and bringing contracted capacity into operation.

What to watch next

The most important FY27 measure will be how much of the forward order book converts into billing utilisation. The company's expectation of approximately 197 megawatts converting during the year provides a clear operational benchmark.

Capital expenditure against the A$5.3 billion to A$5.8 billion guidance range will also be important, along with updates on S4 and other major developments. Revenue and EBITDA will need to track the guided ranges to demonstrate that construction activity is translating into operating earnings.

NEXTDC (ASX:NXT) enters its next phase with an unusually large amount of demand already contracted, but most of that demand still needs to be turned into physical, powered capacity. The central issue for FY27 is therefore execution: building on time, securing power and converting signed megawatts into Recurring Revenue without allowing the scale of the capital programme to weaken financial flexibility.
