NEXTDC Limited

The Business

NEXTDC builds and operates wholesale data centres, leasing power and space to hyperscale cloud providers, enterprises and government agencies under long-term contracts. It is the largest independent data centre operator listed on the ASX, holding the deepest contracted power pipeline in the country thanks to early, oversized grid connection applications. Unlike colocation resellers, NEXTDC owns and constructs its own facilities across Sydney, Melbourne, Brisbane and Perth, and is now extending the model into Malaysia and Japan. Revenue is contracted years in advance, tied to the megawatts (MW) of power capacity a customer commits to, not to short-term occupancy.

Recent Performance

Revenue grew 16% in FY26, a solid but unremarkable base rate given the company was still mid-construction on its next wave of capacity. The market has since re-rated the stock sharply on the AI infrastructure narrative, pricing in the fact that the contracted backlog is about to convert into billed revenue. Guidance for FY27 points to revenue growth of roughly 55%, and the market has largely taken management's guidance at face value given a track record of beating forecasts in recent years.

Outlook

Revenue is set to climb materially over the next three years as 565MW of contracted capacity is progressively switched on through FY30. Because much of the cost base is fixed, EBITDA margin should expand from around 61% currently toward the mid-60s over the same period, and the group is expected to turn NPAT-positive within the forecast window for the first time in years. The offsetting force is capital intensity: a multi-billion dollar capex programme in FY27 alone keeps free cash flow deeply negative through the forecast period, meaning the earnings recovery and the cash flow story are moving in opposite directions for some time yet.

Key Risks

Cost of capital is the dominant swing factor for a business that needs several billion dollars a year of external funding to complete its build programme. Sustained higher rates compress the value of contracted cash flows that sit years in the future and directly increase the cost of financing construction that has not yet started generating revenue. A second risk is a peaking hyperscaler capex cycle: a shift toward more efficient AI models or a broader pullback in cloud infrastructure spending would slow new contract signings, even though the existing backlog is contractually protected for several years. Leverage compounds both risks. Interest cover currently sits at a tight 1.6 times earnings, leaving little headroom before covenant pressure builds if billing conversion slows or funding costs rise further.

What to Watch

The thesis-defining event is the FY27 half-year result in February 2027, which will show the actual net revenue per megawatt achieved on the first wave of hyperscale billing. This single data point resolves much of the uncertainty around how quickly, and how profitably, the contracted backlog converts into cash earnings.

• Feb 2027 FY27 H1 results — actual revenue per MW achieved on the hyperscale ramp, the single biggest input into the earnings outlook.
• H1 2027 JVCo capital recycling announcement — a possible transaction that would de-risk the balance sheet by bringing in outside capital against existing assets.

Company Description

NEXTDC designs, builds and operates wholesale data centres across Australia, with facilities in Sydney, Melbourne, Brisbane and Perth and new developments underway in Malaysia and Japan. The business leases power capacity and rack space to three broad customer groups: hyperscale cloud providers (the fastest-growing segment), large enterprises, and government agencies, typically under contracts running five to fifteen years. Unlike interconnection-focused peers, NEXTDC's value proposition centres on secured power and land, not network density. The group currently has 740MW of contracted capacity signed but not yet billing, worth an estimated $11.9bn in binding lease payments over the life of those contracts, the single largest driver of earnings over the next four years.

Where the Growth Is

Nearly all near-term earnings growth comes from converting the 740MW contracted backlog into billed revenue, with 565MW expected to switch on progressively through FY30. Because facility and corporate costs are largely fixed once a data hall is built, each megawatt of new billing carries high incremental margin, producing operating leverage of roughly 1.0 to 1.6 times revenue growth. This mechanical process, not new sales, is what drives the bulk of forecast EBITDA growth over the next three years.

Competitive Position

NEXTDC's advantage is physical, not brand-based: it holds more than 5 gigawatts of pipeline with confirmed grid connections, while competitors now face two to three year queues to secure equivalent power. That gap is widening as regulators tighten new grid approvals, effectively grandfathering NEXTDC's existing pipeline while making it harder for rivals to catch up. Customer switching costs reinforce the position: once a hyperscaler deploys servers into a facility, relocation costs can exceed $50m, and retention rates across the sector run above 95%. That said, the advantage has a shelf life. Grid bottlenecks eventually resolve, and large hyperscalers retain the option to self-build. We think the current edge holds for roughly five to seven years before competitive supply catches up, not indefinitely.

Management & Capital Discipline

Management has raised $9.75bn across three separate capital tranches in relatively favourable markets, funding the largest simultaneous data centre construction programme in ASX history. Every dollar of free cash flow is being reinvested; there has been no dividend and none is expected before FY33 at the earliest. The team's 14-year record of beating its own guidance is genuinely strong. The honest caveat is that this record was built entirely during a secular AI demand upswing: management has never had to navigate a hyperscaler capex downturn, so its discipline in a harder environment remains unproven.

Financial Position

The balance sheet is stretched by design. Multi-billion dollar capex commitments across FY27 and FY28 keep free cash flow deeply negative, and interest cover sits at a tight 1.6 times earnings. The mitigants are real: $8.7bn of total liquidity, $7.8bn of undrawn facilities, and no debt maturities before December 2029 buy time for growth capex to convert into cash flow. Even so, this is not a business that could comfortably absorb a prolonged downturn in demand or a sustained spike in funding costs.
