Meridian Energy Limited (ASX: MEZ)Share Price and News
Overview of Meridian Energy
Meridian Energy is New Zealand's largest electricity generator, producing power exclusively from renewable sources: hydro, wind, and solar. The company operates seven hydro stations and five wind farms across New Zealand, supplying electricity to homes, businesses, and industries. Meridian also owns Powershop, an online electricity retailer serving customers in New Zealand and Australia. Committed to sustainability, Meridian focuses on reducing carbon emissions and supporting the transition to a low-emissions economy.
Meridian Energy's Company History
Meridian Energy was born out of one of the most significant structural reforms in New Zealand's economic history. In 1998 and 1999, the New Zealand Government broke up the Electricity Corporation of New Zealand — a monolithic state-owned generator that had dominated the country's power sector — into three separate entities. Meridian received the most prized assets in that carve-up: the vast Waitaki River hydroelectric scheme in the South Island and the Manapouri power station, the largest hydro facility in New Zealand. From that foundation, Meridian inherited both enormous generating capacity and an enduring dependence on rainfall and snowmelt that would shape its financial fortunes for decades to come.
For its first fourteen years, Meridian operated as a purely state-owned enterprise, its profits flowing directly to the New Zealand Government as shareholder. That changed in October 2013, when the Fifth National Government partially privatised the company, listing it on the New Zealand and Australian stock exchanges in one of the largest IPOs in New Zealand history. The government retained a majority stake of just over 51%, a position it continues to hold today, meaning Meridian remains a mixed-ownership model — publicly listed but Crown controlled.
Through the 2010s, Meridian expanded its wind portfolio significantly, adding farms across both islands of New Zealand, and entered the Australian electricity retail market through its Powershop brand. It divested its Australian generation assets in 2005 but has since built a presence back across the Tasman through retail operations and smaller generation interests.
In more recent years, the company has pivoted toward solar and battery storage, commissioning a 100MW battery energy storage system and securing consents for several large solar and wind projects as it positions itself for New Zealand's transition to a fully renewable electricity system. As of today, Meridian generates electricity from 100% renewable sources, making it one of the greenest large utilities in the Asia-Pacific region.
Future Outlook of Meridian Energy (ASX: MEZ)
Meridian's full year results for the year ended 30 June 2025, released in August 2025, made for sobering reading. The company swung from a net profit after tax of $429m in FY2024 to a net loss after tax of $452m in FY2025 — a dramatic deterioration driven almost entirely by the consequences of exceptional and prolonged drought conditions across New Zealand's South Island. EBITDAF, the company's preferred earnings measure, fell from $905m to $611m, while underlying net profit — which strips out unrealised derivative movements — collapsed from $359m to just $56m.
The culprit was hydrology. Meridian's business model is fundamentally exposed to rainfall. Two severe droughts during the year reduced hydro production volumes by 11% compared to the prior year, slashing the company's energy margin by 23% from $1.276bn to $982m. To manage the shortfall in generation and maintain security of supply for New Zealand homes and businesses — including exercising the largest demand response option ever called with New Zealand Aluminium Smelters — the company spent approximately $300m on hedge and demand response contracts. Those costs flowed directly through to earnings. Operating cash flows fell sharply, from $667m to $318m.
Against this backdrop, the maintenance of the interim dividend at 6.15 cents per share, and the payment of a final ordinary dividend of 14.85 cents per share, was a statement of balance sheet confidence from the board.
Looking into FY2026, management has signalled a return to more normalised hydrology conditions and committed to capital expenditure of approximately $1 billion during the current calendar year, directed at advancing its consented renewable pipeline — which includes solar developments and new wind farms expected to add over two terawatt hours of generation capacity to the New Zealand system. Retail connections grew 5% during the year to record levels, providing a stronger customer base from which to benefit as conditions normalise.
Is MEZ a Good Stock to Buy?
Meridian Energy is a stock that demands a clear understanding of what you are buying before committing capital. It is not a growth story in the conventional sense, and it is not a technology company. It is a large, government-majority-owned renewable energy utility whose financial performance is materially influenced by the weather — specifically, by how much rain falls on the Southern Alps of New Zealand. In years of good hydrology, it generates strong cash flows and pays attractive dividends. In drought years, as FY2025 demonstrated brutally, earnings can collapse with little warning.
That weather dependency is both the primary risk and, for patient investors, the primary opportunity. Meridian's underlying asset base — its chain of hydro dams on the Waitaki River and Manapouri, its wind farms, and its growing renewable pipeline — is genuinely world class. These are long-lived, low-cost generation assets that cannot be replicated. Their value does not diminish with a drought year; it is simply temporarily obscured. Investors who understand this and can tolerate earnings volatility are, in effect, buying a call option on normalised New Zealand hydrology.
The longer-term structural backdrop is genuinely favourable. New Zealand has committed to ambitious electrification targets as part of its climate policy, and the country's electricity demand is expected to grow materially as transport, industrial heat, and heating systems electrify. As the country's largest renewable generator with a consented pipeline of new projects, Meridian is structurally well placed to benefit from that demand growth. The company's record retail connections — up 5% in FY2025 despite a difficult year — suggest the customer proposition under its Meridian and Powershop brands is competitive.
The dividend yield, at current prices, is reasonably attractive for income investors, and the New Zealand Government's majority ownership provides a degree of implicit stability. The principal risk beyond hydrology is regulatory — as a large utility in a small market, Meridian operates under close government scrutiny, and any moves to cap electricity prices or restructure the market could affect its profitability. For investors comfortable with that combination of risks, Meridian represents a patient, income-oriented holding with credible long-term growth optionality.
