NEXTDC (ASX: NXT) lowers EBITDA forecast after Jemena suspends Melbourne grid works

NEXTDC Limited (ASX: NXT), the Brisbane-headquartered Australian data centre developer and operator, has reduced its FY27 net revenue guidance to A$475 million to A$500 million after delays to electricity network upgrades at its M3 Melbourne facility prevented the company from delivering additional contracted customer capacity on schedule. The 21 October 2026 announcement also cut underlying EBITDA guidance to A$245 million to A$265 million, compared with the previous forecast of A$385 million to A$410 million. Electricity distributor Jemena has suspended parts of the required grid works following community and stakeholder opposition, with the next increase in power supply now expected during FY28 rather than FY27. NEXTDC reported A$8.675 billion in liquidity at 30 September but has placed new development projects and land acquisitions on hold while reviewing its capital programme.

Why has NEXTDC reduced FY27 net revenue and EBITDA guidance by approximately A$140 million?

NEXTDC previously expected FY27 net revenue of A$615 million to A$640 million. The revised range of A$475 million to A$500 million represents a A$140 million reduction at both ends of the forecast. Underlying EBITDA guidance has similarly declined by A$140 million, from A$385 million to A$410 million to A$245 million to A$265 million. The parallel revisions reflect the removal of expected revenue and attributable EBITDA associated with affected M3 Melbourne customer contracts.

The company has confirmed that its August guidance included approximately A$140 million of net revenue and underlying EBITDA from those contracts. The revised outlook excludes their contribution, including capacity that had already begun billing, because the available electricity supply cannot be relied upon to support the full contracted power ramp. This distinction is commercially important because the revision is not confined to revenue from capacity that has yet to be installed or commissioned. It also involves uncertainty over the continued billing arrangements for existing contracted services.

NEXTDC is working with the affected customer to establish a revised power delivery schedule. However, the company has acknowledged that contractual service-level credits could reduce underlying EBITDA below the new guidance range. Certain contractual circumstances may also give the customer termination rights. The announcement therefore establishes a broader commercial uncertainty than a straightforward delay in recognising future revenue.

Data centre contracts can involve substantial capital commitments before customers begin paying for the full contracted capacity. NEXTDC may construct buildings, electrical systems and cooling infrastructure in anticipation of a particular delivery schedule. If external grid power is unavailable, those assets may remain underutilised despite being physically complete. The financial effect depends on the timing of electricity availability and the terms agreed with customers.

How has Jemena’s suspension of electricity network works affected the M3 Melbourne development?

Jemena Electricity Networks has informed NEXTDC that portions of the electricity infrastructure programme serving M3 Melbourne have been suspended because of community and stakeholder opposition. The network operator does not currently expect to recommence the relevant works before February 2027. As a result, NEXTDC anticipates that the next increase in grid supply will not become available until FY28. This delays the company’s ability to deliver the next stage of contracted power-dependent data centre services.

M3 Melbourne is part of NEXTDC’s wider Melbourne data centre portfolio, which serves enterprise, cloud and other high-density computing customers. Large data centres depend on reliable high-voltage electricity connections capable of supporting continuous computing, cooling and associated infrastructure. The electricity network connection therefore represents an essential component of commercial capacity, rather than a peripheral utility service. Buildings and computing infrastructure cannot generate the expected contracted revenue without sufficient dependable power.

The delay also highlights the different parties involved in developing data centre capacity. NEXTDC controls the development and operation of its facilities, while external electricity network operators are responsible for certain infrastructure necessary to supply additional power. Community concerns and approval processes can influence the network operator’s timetable independently of the data centre owner’s construction progress. This introduces an execution risk that cannot be resolved solely through faster building works.

NEXTDC has not announced that the relevant customer contracts have been cancelled. However, the company’s guidance no longer assumes that the affected contracts will contribute the previously forecast revenue and EBITDA during FY27. The eventual commercial outcome will depend on the revised power schedule, customer negotiations and contractual rights. Confirmation of network construction restarting would be a material milestone, but sufficient power still needs to be delivered before the intended revenue can resume.

Why has NEXTDC reduced its FY27 capital expenditure programme to A$4.5 billion to A$5 billion?

NEXTDC has reduced FY27 capital expenditure guidance to A$4.5 billion to A$5 billion, compared with the previous range of A$5.25 billion to A$5.75 billion. The reduction is approximately A$750 million at each end, representing around 13% to 14% of the original forecast. The company is prioritising projects associated with contracted customer capacity expected to be delivered over the next 12 to 18 months and developments already approaching completion. This represents a tightening of investment priorities while the M3 power timetable remains uncertain.

The revised capital expenditure range includes approximately A$500 million in reimbursable customer fit-out expenditure and A$230 million in capitalised interest. These components affect the interpretation of the headline spending figure because some expenditure may be recoverable under customer arrangements, while capitalised interest reflects financing costs associated with qualifying developments. Neither item should be treated as an ordinary operating expense in the same way as salaries or maintenance. A complete assessment of funding requirements must consider the timing of customer reimbursements and the accounting treatment of borrowing costs.

NEXTDC has temporarily suspended new development projects and land acquisitions pending a broader capital expenditure review. Its board expects to disclose the outcome by the company’s annual general meeting on 20 November 2026. The review is intended to align construction commitments more closely with contracted capacity and available funding. It may influence the timing of future developments across the broader portfolio.

The decision does not establish that demand for data centre capacity has disappeared. Instead, it shows management reassessing the pace at which capital should be committed while important delivery conditions remain unresolved. Reducing expenditure may preserve financial flexibility, but it could also delay future revenue if projects are deferred. The financial trade-off will depend on how quickly electricity supply and customer demand can be converted into billable capacity.

What does NEXTDC’s A$8.675 billion liquidity position mean after the guidance downgrade?

NEXTDC reported total liquidity of approximately A$8.675 billion at 30 September 2026. This provides substantial financial resources for an operating model that requires large upfront investments in data centre infrastructure. However, liquidity includes financing capacity and should not automatically be equated with unrestricted cash available for discretionary spending. Access to particular debt facilities may depend on contractual conditions and financial covenants.

The company has indicated that it remains compliant with its financing covenants. It is nevertheless reviewing the potential consequences of the M3 delays for the availability of senior debt funding and other financing arrangements. Lower projected EBITDA can influence debt metrics even when a business retains substantial cash and committed facilities. Accordingly, the effect of the guidance revision extends beyond the current year’s income statement.

NEXTDC’s development strategy has increasingly involved financing large contracted data centre projects before the related revenue is fully recognised. This can create periods of elevated capital expenditure and financing needs during construction and commissioning. The company must therefore maintain sufficient financial flexibility to bridge the period between investment and customer billing. Delays in power delivery can lengthen that interval and increase the importance of debt terms.

The revised investment programme may help moderate near-term funding requirements. However, financing flexibility will also depend on the value and commercial terms of existing contracts, potential customer credits and the revised construction schedule. The reported liquidity position is a strength, but it does not eliminate execution risk. Future disclosures will need to reconcile development expenditure with available financing and the timing of revenue generation.

How could the M3 power delay affect NEXTDC’s investment property valuations and reported profit?

NEXTDC has warned that the M3 Melbourne delay is likely to affect the fair value of certain investment properties. The company has not quantified the effect and expects to reflect the relevant assessment in its results for the half-year ending 31 December 2026. The revised FY27 underlying EBITDA guidance excludes any investment property fair value movement. That distinction matters because valuation changes may influence statutory accounting results separately from operational earnings.

Data centre valuations can depend on contracted revenue, expected completion dates, capital expenditure and assumptions about future cash generation. A delay to electricity availability may push expected revenue further into the future, potentially changing the present value of projected cash flows. The outcome will depend on the final delivery timetable and the assumptions applied by valuation specialists. A reduction in accounting value would not necessarily involve an immediate equivalent cash payment.

The company must also assess how the delay affects the commercial position of the associated data halls. Capacity that has been constructed but cannot reliably operate at the required electrical load may have a different earnings profile from fully operational contracted capacity. If customers renegotiate delivery schedules, the financial model may change again. This uncertainty makes the next formal valuation particularly important.

Underlying EBITDA provides information about operating performance, but it cannot fully describe the economics of a capital-intensive development business. Financing costs, depreciation and property valuations can materially influence reported earnings. The M3 situation demonstrates why investors must consider contracted capacity, available power, capital expenditure and liquidity together. Future reporting will establish the accounting consequences after the revised operating assumptions have been incorporated.

What does the Melbourne electricity delay reveal about the economics of Australia’s AI and cloud data centre expansion?

Demand for large-scale computing infrastructure has supported substantial investment in Australian data centres. Cloud platforms, enterprise computing and artificial intelligence systems require reliable access to electricity, cooling and network connectivity. Increasing computing density can raise the electrical requirements of individual facilities, making grid infrastructure an important determinant of development capacity. NEXTDC’s M3 experience demonstrates that obtaining customer contracts and constructing facilities do not necessarily guarantee timely electricity availability.

The challenge is particularly relevant to developments requiring substantial increases in grid supply. Electricity network upgrades may involve transmission or distribution works, approvals and community consultation beyond the data centre site itself. These processes can have timelines that differ from commercial leasing and construction schedules. Developers must therefore coordinate several independent activities before contracted capacity becomes operational.

NEXTDC operates a portfolio of facilities across major Australian markets and has been expanding to accommodate larger customer requirements. Its ability to deliver new capacity depends on execution across construction, power and customer commissioning. The Melbourne delay does not establish that similar issues will affect every project. Nevertheless, it illustrates a constraint that may become increasingly important as demand for electricity-intensive computing expands.

The company’s immediate priority is resolving the M3 delivery schedule while limiting the financial effects of the interruption. Reaching an agreement with the affected customer could provide greater certainty about future billing and contractual obligations. Restarting the necessary grid works would address another critical dependency. The combination of those developments will determine when the delayed capacity can begin contributing to revenue.

What must NEXTDC achieve before its reduced FY27 guidance can be considered stable?

NEXTDC has established a revised earnings forecast based on excluding the affected M3 contracts, but it has not resolved every potential consequence of the power delay. Service-level credits, customer termination rights and property valuation adjustments remain relevant uncertainties. The company must also finalise its wider capital expenditure review and assess any implications for financing arrangements. These developments could influence reported results even if other data centre operations perform as expected.

The next specific milestone is the board’s capital expenditure update scheduled for the 20 November annual general meeting. That should provide more information about which developments remain priorities and how management intends to allocate capital. Progress with Jemena and the affected customer will be equally important. A confirmed power schedule would allow the company to reassess the timing of contracted revenue.

The M3 announcement highlights the financial consequences of external infrastructure constraints for a rapidly expanding data centre operator. NEXTDC retains substantial liquidity and contracted customer relationships, but the timing of power delivery has materially changed its FY27 earnings outlook. The most important evidence will be a credible revised connection schedule, agreement on customer obligations and confirmation that financing remains aligned with the development programme. Until those issues are resolved, the lower guidance reflects both deferred revenue and continuing execution uncertainty.
