Backlash Wipes A$140M Off NextDC Guidance as Anthropic Warns

NEXTDC, the ASX-listed data centre operator, on 21 October 2026 removed approximately A$140 million of each of net revenue and Underlying EBITDA from its fiscal 2027 guidance, after the electricity distributor Jemena suspended power works for its M3 Melbourne data centre. Jemena attributed the suspension to community and stakeholder opposition to the works and to the absence of local council consent, according to NEXTDC’s release.

The shares traded at A$5.28 on the morning of 21 October, against A$9.18 before a trading halt, about 42% lower by our arithmetic; Bloomberg’s headline put the plunge at 44%. The same week, Anthropic’s draft IPO prospectus warned that political resistance to data centres has “become more organized and coordinated across jurisdictions”, the Wall Street Journal reported.

Business Pill · GRID COST ALLOCATION

A short explainer on how the cost of grid upgrades is shared. It teaches the general idea only and says nothing about any company in this story.

What NEXTDC Disclosed

NEXTDC now expects fiscal 2027 net revenue of A$475 million to A$500 million, down from A$615 million to A$640 million, and Underlying EBITDA of A$245 million to A$265 million, down from A$385 million to A$410 million. The revised figures exclude the affected M3 contracts, which the August guidance included at approximately A$140 million of each.

The company said Jemena suspended parts of its 66kV line works in September 2026 and does not expect to restart them before February 2027. It now expects the next increase in grid supply to M3 during fiscal 2028.

Chief executive Craig Scroggie said: “With M3 revenue deferred, we have paused projects not backed by customer contracts and put that capital behind the capacity our customers have already contracted.”

• Capex. Fiscal 2027 capital expenditure guidance falls to A$4,500 million to A$5,000 million, from A$5,250 million to A$5,750 million, and all new development projects and land acquisitions are on hold.
• Contracts. The affected contracts provide for service level credits when capacity is late and, in some circumstances, give the customer rights to terminate, the release says.
• Balance sheet. NEXTDC reported A$8,675 million of liquidity at 30 September 2026 and said it is in compliance with its financial covenants.

The Backlash Ledger

NEXTDC is not the only place where local opposition to AI infrastructure showed up as a cost, a risk factor or a product this week, by our reading of the sources:

• An IPO risk factor. Anthropic’s draft prospectus cited growing political resistance to data centres, the Journal reported.
• An insurance product. Arbol launched what it calls Data Center Regulatory Moratorium Cover, which pays a set amount if a covered government action stays in effect past a waiting period, Artemis reported. Its chief executive, Sid Jha, said: “A moratorium or construction hold can strand hundreds of millions in committed capital, and standard policies do not respond.”
• A court ruling. A federal court in Mississippi denied the US Justice Department’s attempt to dismiss the NAACP’s Clean Air Act lawsuit against xAI over a gas-fired power plant supporting its Colossus 2 data center, according to Earthjustice, which represents the plaintiffs.
• A campus protest. A few dozen San Diego State University students called on the California State University system to end its contract with OpenAI, KPBS reported, with signs that included the environmental harm caused by data centres.

Update, 21 October: Canberra Sets a Grid Condition

Australia welcomes data centres if they “contribute to the energy grid,” Treasurer Chalmers said, according to the headline of a CNBC video interview; we could read only that headline, not a transcript.

Reuters, in a headline we read without the full text, reported that NEXTDC shares “shed 44% on revenue delay,” the same figure as the Bloomberg headline cited above.

Connecting the Coverage

When NEXTDC halted its shares over the M3 delay, our piece on AI’s local limits reported that Citigroup analysts put up to A$25 million of fiscal 2027 operating earnings at risk, as Bloomberg reported. The amount NEXTDC has now taken out of guidance is larger: approximately A$140 million of Underlying EBITDA, although the company says the capacity remains under contract, subject to the customer’s rights, and that its actual fiscal 2027 results will include the contribution of the affected contracts.

As we read it, the pattern echoes Microsoft’s exit from Nscale’s Loughton site, where the Telegraph reported that grid bosses do not expect a power supply until the 2030s. On the money side, our piece on Anthropic’s draft prospectus set out its compute commitments, and our neocloud shakeout piece covered credit stress among the operators that build and rent this capacity.

As we read it, the common thread is the gap between a signed contract and a powered building: when consent or power slips, the revenue slips with it.

The Structural Read

As we read it, the cut is about timing as much as demand: NEXTDC says the capacity remains under contract, subject to the customer’s rights, and that construction of the data halls is continuing.

As we read it, the release links consent to financing: NEXTDC says its ability to draw its undrawn senior debt depends on expected billing profiles, and that delays to grid supply at M3 could be such a change.

As we read it, the week’s other items price the same risk from other sides: a risk factor in Anthropic’s draft prospectus, as the Journal reported, and an insurance cover for moratoriums, as Artemis reported.

Three Implications

GUIDANCE NEXTDC removed approximately A$140 million of each of net revenue and Underlying EBITDA from fiscal 2027 guidance.

CAPITAL Capital expenditure guidance falls to A$4,500 million to A$5,000 million, and new development projects and land acquisitions are on hold.

POWER Jemena does not expect to restart the suspended works before February 2027, and NEXTDC expects the next grid increase at M3 in fiscal 2028.

The Business Engineer Lens

This story maps onto the Business Engineer framework The State of AI Data Centers.

The framework puts it this way: “The structural bottleneck isn’t computing, it’s electrons.”

As we read it, M3 fits that description on the reported facts: the data halls are being built, but the next increase in grid supply depends on works that Jemena suspended. The framework was published in December 2025 and does not discuss NEXTDC.

What Is Not Established

NEXTDC says it cannot yet reliably estimate the fiscal 2027 contribution of the affected contracts, and that service level credits could push Underlying EBITDA below the revised guidance. It has not named the customer. The sources do not say whether the customer will exercise any termination right, how many projects Arbol’s cover will insure, or how the xAI case will end. The grouping of these events is ours, and the share figures are from market data read on the morning of 21 October, not a closing price.

The Bottom Line

NEXTDC took approximately A$140 million of net revenue and Underlying EBITDA out of its fiscal 2027 guidance on 21 October 2026, after power works for M3 Melbourne were suspended amid community and stakeholder opposition. As we read it, local consent has become a line item: in guidance, in an IPO risk section and in an insurance policy.
