MEZ: Renewable Energy Giant - The Most Expensive Free River in the World
In a Nutshell
Executive Summary
In a Nutshell
Meridian Energy is New Zealand's largest electricity generator, running irreplaceable hydro dams and wind farms that feed power to homes and businesses across Australasia. At A$4.73 versus our fair value of A$2.22, the stock is 113% overvalued. The entire gap comes down to one assumption: the market is pricing Meridian as though interest rates will fall sharply, while current rate levels suggest they shouldn't be paying anywhere near this much.
Investor Profiles
| Profile | Rating | Rationale |
|---|---|---|
| Income | ★★☆☆☆ | The FY26 dividend of NZD 12.8 cents per share (approximately A$11.3 cents) yields just 2.4% at the current price — well below what a utility should offer. Worse, a dividend cut looks likely in FY27 as earnings normalise and capital spending peaks. Income seekers should note the payout ratio sits at 85–90%, so there is little buffer if conditions soften. |
| Value | ★☆☆☆☆ | At A$4.73 against a fair value of A$2.22, the stock is trading at more than double what a standard discounted cash flow supports at current interest rates. There is no margin of safety — the bull case only reaches A$2.85. Re-rating would require New Zealand's 10-year bond yield to fall roughly 150 basis points from here, which is a macro bet, not a value proposition. Not suitable for value investors. |
| Growth | ★★☆☆☆ | Revenue is forecast to dip 4.3% in FY27 before recovering at 4% annually — roughly in line with nominal GDP. Reported earnings per share collapse 82% in FY27 as weather-driven profits normalise, then recover from FY28. New generation assets (Ruakākā solar, Te Rāhui wind) add capacity over time, but the growth story is slow and already priced at a premium. Not suitable for growth investors at current levels. |
| Quality | ★★★☆☆ | The business scores 8 out of 10 on quality — a genuinely wide moat built on physical hydro infrastructure that cannot be replicated. Management has executed well: the Harapaki wind farm was delivered on time, and two acquisitions were integrated inside six months. The structural weakness is capital efficiency: ROIC sits at just 3.8–4.6%, well below our 7.9% cost of capital, a consequence of carrying assets at revalued fair value on the balance sheet. |
| Thematic | ★★★★☆ | Meridian is the cleanest expression of the New Zealand energy transition available on the ASX. It generates 100% renewable electricity, holds New Zealand's largest development pipeline at 15.3 terawatt-hours, and benefits directly from the structural decline of domestic gas supply — a geological reality that permanently raises the value of hydro. The thematic case is strong; the problem is that every other investor can see it too, and the premium is already embedded in the price. |
Meridian is best suited to thematic investors with a long time horizon and high conviction that New Zealand interest rates will normalise meaningfully over the next two to three years. The business quality is undeniable, but the return on offer at current prices is driven almost entirely by a macro call on the rate cycle rather than by anything the company itself is doing.
Executive Summary
Meridian Energy owns and operates New Zealand's largest portfolio of hydro and wind generation assets, selling electricity to homes and businesses through its retail brands. The company earns money on the margin between what it costs to generate or procure power and what it charges customers — a figure it calls energy margin, which stood at NZD $708 million in the first half of FY26 alone.
That half-year result was exceptional. Rainfall across the South Island ran at 144% of the long-run average, filling hydro storage to near-record levels and driving generation output to an all-time high. The company is 100% renewable, carries a BBB+ credit rating, and recently completed two acquisitions while delivering the Harapaki wind farm on schedule. By almost every operational measure, Meridian is performing well.
The investment question is whether that quality justifies the price. Our discounted cash flow model — using a 7.9% discount rate anchored to current New Zealand borrowing costs — produces a fair value of A$2.22. The market is paying A$4.73. The difference is not explained by differing views on earnings or growth; our operating assumptions sit below every historical benchmark. The gap exists because the market appears to be pricing Meridian as though interest rates are already 150–200 basis points lower than they are today.
At A$4.73 versus fair value of A$2.22, the stock is 113% overvalued on current rate assumptions.
Results & Outlook
What happened?
Meridian's first half of FY26 was driven by weather rather than strategy. South Island rainfall ran at 144% of average, pushing generation to a record 7,479 gigawatt-hours. That volume, combined with the December 2024 acquisition of New Zealand Windfarms, lifted energy margin to NZD $708 million — 59% above the same period last year. EBITDAF reached NZD $506 million for the half.
| Metric | FY26E | FY27E | FY28E | FY29E |
|---|---|---|---|---|
| Energy Margin (NZD $m) | 1,150 | 1,100 | 1,144 | 1,190 |
| EBITDAF (NZD $m) | 750 | 676 | 739 | 772 |
| Underlying NPAT (NZD $m) | 175 | 33 | 83 | 103 |
| EPS (NZD, basic) | $0.067 | $0.012 | $0.031 | $0.038 |
| DPS (NZD) | $0.128 | $0.057 | $0.112 | $0.137 |
| EBITDAF Margin | 65.2% | 61.5% | 64.6% | 64.9% |
What's next?
FY27 is the normalisation year investors need to prepare for. Hydrology will revert toward average, spot electricity prices will recover from current depressed levels, and the full-year cost of running two technology platforms simultaneously — Meridian's legacy system alongside the new Kraken platform — will weigh on margins. The combination drags forecast NPAT down 82% to just NZD $33 million, and a dividend cut from NZD 12.8 cents to around 5.7 cents looks probable.
The recovery begins in FY28. Kraken dual-running costs are expected to cease by mid-FY27, saving an estimated NZD $20–25 million annually from FY28 onwards. The Ruakākā solar farm should also contribute its first full year of generation. Beyond that, the Te Rāhui wind joint venture and the Mt Munro wind project are the next meaningful capacity additions. New Zealand's structural gas supply decline — output from the Pohokura field has fallen roughly 60% — provides a permanent floor under wholesale electricity prices that underpins the medium-term earnings recovery.

The single biggest risk to any bearish view on Meridian is interest rates falling faster than expected. Our 7.9% discount rate is derived mechanically from the current New Zealand 10-year government bond yield and a standard equity risk premium — it reflects today's rate environment, not a hoped-for future one. Every 50 basis points the discount rate falls, our fair value rises by roughly A$0.28 per share. If New Zealand's 10-year yield dropped to 3.5% within two years — consistent with a full rate normalisation cycle — our fair value would rise to approximately A$3.50, narrowing the gap to market significantly but still leaving the stock overvalued by around 35%. Investors buying Meridian today are not primarily making a judgment about renewable energy, hydro dams, or the New Zealand electricity market. They are making a bet that central bank rate cuts arrive quickly and durably. That may prove correct, but with the Reserve Bank of Australia having just raised rates in February 2026 and trimmed-mean inflation still running at 3.4%, the evidence for imminent rate normalisation is thin.
