Meridian Energy Limited

The Business

Meridian is New Zealand's largest electricity generator, controlling roughly 30% of national generation capacity through hydro schemes at Waitaki and Manapouri, supplemented by a growing wind and solar fleet. The retail arm serves 455,000 customers under the Meridian and Powershop/Flick brands, up from around 380,000 two years ago. The business is vertically integrated: generation feeds retail, and the combination smooths the volatility that a pure generator would otherwise carry. The New Zealand government owns 51% of the register, which anchors the balance sheet but also limits takeover premiums and capital allocation flexibility.

Recent Performance

FY26 EBITDAF of NZ$1,051 million rebounded sharply from a drought-affected FY25, as hydro inflows ran at 122% of the long-term average. That recovery is transient, a hydrology bounce rather than a structural earnings step-up, though the underlying retail growth beneath it is durable. The stock has re-rated well ahead of this recovery, now trading at roughly 16 times forward EBITDAF, a premium to every listed New Zealand generator peer.

Outlook

Revenue growth is modest and expected to build gradually over the next several years, as new wind and solar capacity and retail customer additions offset a structural decline in wholesale prices. Margins are expected to compress steadily over the same period, as transmission and employee costs grow faster than revenue. Dividends per share are expected to grow at a modest pace, funded by a payout ratio of roughly 80%.

Key Risks

The largest risk to the thesis is a structural decline in wholesale electricity prices, as more than 15GW of new renewable supply is scheduled to enter the New Zealand market over the coming years. Forward prices have already fallen roughly 20% since February 2026, an early signal that this shift is underway rather than a temporary dip. Hydrology remains a permanent source of earnings volatility: a severe, multi-year drought would compress EBITDAF materially, echoing the shortfall experienced in FY25, and the balance sheet can absorb one bad year comfortably but would come under more pressure from consecutive ones. A smaller but structurally significant risk sits with the Tiwai Point aluminium smelter, which consumes roughly 23% of Meridian's generation, and with a Competition Task Force review that could push for separation of generation from retail. Both are lower-probability outcomes, but each would meaningfully alter the earnings base if they crystallise.

What to Watch

• February 2027 FY27 full-year result and FY28 guidance — the thesis-defining event, testing whether energy margin growth is accelerating toward the pace needed to justify the current premium.
• Q4 2026 RBNZ rate decision — a cut in the official cash rate would narrow the discount-rate assumptions embedded in the current share price.
• Q2 2027 Competition Task Force interim report — a structural separation mandate would be a negative catalyst for the vertically integrated model.

Latest Developments

Forward wholesale electricity prices have fallen roughly 20% since February 2026 as the scale of the incoming renewable pipeline became visible to the market, a leading indicator for the margin compression already embedded in our forecast.

Company Description

Meridian Energy is New Zealand's largest electricity generator and retailer, vertically integrated across generation and supply. Hydro generation, anchored by the Waitaki chain and Manapouri, provides roughly 85% of output at effectively zero marginal cost. Wind and solar capacity is expanding from a smaller base and is the primary source of new generation growth. The retail division, trading as Meridian and via the Powershop and Flick brands, serves 455,000 residential and commercial customers. Government ownership of 51% underpins the balance sheet and credit standing but constrains buybacks and takeover activity.

Where the Growth Is

Retail customer growth is the clearest structural driver, with the book expanding from around 380,000 to 455,000 customers, a 12% increase year on year off an already growing base. Combined with new wind and solar capacity coming online through the rest of the decade, energy margin growth is expected to step up from roughly 2% to around 3% annually in that window, contributing a meaningful base of incremental earnings over the period.

Competitive Position

The competitive advantage is physical rather than commercial: hydro dams on this scale cannot be replicated in New Zealand, and the 35-year Waitaki reconsent locks in access to the resource for decades. Generation share has held stable at roughly 30% for years, a sign the position is not eroding under competitive pressure. Barriers to entry are high given the difficulty of consenting new large-scale hydro, and the fully renewable generation mix gives Meridian access to green financing and index inclusion that thermal-exposed peers cannot match. The durability of this position extends well beyond a decade, though it protects the resource, not the price paid for access to it.

Management & Capital Discipline

Management maintained the dividend through the FY25 drought by drawing on balance sheet capacity rather than cutting the payout, a decision that preserved income continuity for shareholders. The announced NZ$5 billion, ten-year capital programme is more ambitious than the pace we model, and the returns on that spending sit only marginally above the cost of capital. One honest observation: management's commentary tends to credit portfolio management and execution for what is substantially a cyclical hydrology recovery, overstating the internal contribution to the FY26 rebound.

Financial Position

The balance sheet carries a BBB+ credit rating with net debt at roughly 1.6 times EBITDA, well below the covenant ceiling, and a NZ$1 billion undrawn facility for headroom. Zero marginal cost generation means the business remains cash generative even in weak wholesale price environments. This is a business built to withstand a downturn; drought and price cycles pressure earnings, not solvency.
