NextDC shares plunge 42% as Melbourne power delays slash FY27 revenue outlook to $309M-$325M

NextDC shares fell 42.1% to A$5.32 on Wednesday, their lowest since January 17, 2018, after the Australian data centre operator cut its fiscal 2027 outlook. The company blamed delays to power works at its M3 Melbourne facility. Jemena Electricity Networks suspended parts of the project because of community and stakeholder opposition, so the next increase in grid supply is not expected until fiscal 2028. NextDC now expects net revenue of A$475 million to A$500 million, down from A$615 million to A$640 million. It forecasts underlying EBITDA of A$245 million to A$265 million, down from A$385 million to A$410 million. It also cut capital expenditure guidance to A$4.5 billion to A$5 billion from A$5.25 billion to A$5.75 billion. New projects and land purchases are on hold, with the board due to report by its annual general meeting on November 20.

SpaceX Q3 earnings smash expectations as AI revenue soars.

SpaceX Q3 earnings smash expectations as AI revenue soars. Power Problems NextDC shares plummet 40% after slashing revenue guidance. 4:39pm today More news: Data centre builder NextDC's shares plummeted at the open after the company confirmed its M3 facility in Melbourne faces power delays amid community opposition. The company has also paused work on all uncontracted projects and potential land purchases, and is considering selling landholdings to reduce the risk of breaching debt covenants. At 10:08am AEDT, NextDC shares had fallen 40% to $5.51 per share. Citi analyst Siraj Ahmed described the fallout in a note to clients: "Earnings impact much higher than expected". Ahmed also noted that NextDC "is reducing capex on future land acquisitions and discretionary capex, which should help with financial covenants however it does put [NextDC] in a competitively weaker position from a medium-term perspective". 2:55pm today NextDC cuts FY27 guidance after power delays at Melbourne site. The news: Data centre operator NextDC has slashed its full-year revenue, earnings and capital expenditure guidance following power delays to its M3 site in Melbourne. The numbers: NextDC has revised down its FY27 net revenue guidance, excluding the contracts affected by the M3 delays, from $615-640 million to $475-500 million. Underlying EBITDA guidance, excluding the M3 contracts, has been lowered from $385-410 million to $245-265 million. Full-year capex guidance has been cut from $5.25-$5.75 billion to $4.5-5 billion. The context: NextDC said the revised guidance reflects delays to electricity network works by Jemena Electricity, which will defer the next increase in grid supply to M3 to FY28. This will push back the delivery and billing of contracted capacity at the site. Jemena has suspended parts of the network works due to community and stakeholder opposition and to the "absence of local council consent", which is pending further consultation. The Victorian government's planning decision on development of stages six and seven of M3 is now expected after the Victorian state election on 28 November 2026. What they said: "We have taken the affected M3 contracts out of FY27 guidance until we can reliably estimate their contribution," said NextDC chief executive Craig Scroggie. "The August guidance included approximately $140 million of each of net revenue and underlying EBITDA from those contracts. The timing and scale of their contribution remain uncertain."
