Meridian Energy (NZSE:MEL) Climbed, What Is Behind The Fresh Attention?

Meridian Energy (NZSE:MEL) just reported August 2026 operating data, with monthly generation of 1,432 GWh compared with 1,179 GWh in August 2025. That shift gives investors fresh information on recent portfolio performance.

Recent trading has picked up, with Meridian Energy’s share price gaining 2.24% over the last day and 3.99% over the past week, even though it is still down 9.29% on a 90 day share price return basis. The 1 year total shareholder return sits at 1.89%, which suggests short term momentum is improving while longer term investors have seen steadier but more modest gains.

Meridian Energy appears to be a solid renewable utility based on recent operating and shareholder returns, but the share price move this month raises a sharper question. Are you paying a fair price for that quality, or stretching for it?

Price-to-Earnings of 111.4x: Is it justified?

Valuation work on Meridian Energy presents a split picture, with the stock trading at NZ$5.47 while our DCF model points to a future cash flow value of NZ$9.84. At the same time, the P/E ratio of 111.4x signals a very full earnings multiple compared with peers.

The P/E multiple measures how much investors are currently paying for each dollar of net profit. For a renewable utility like Meridian Energy, a higher P/E can reflect expectations for steadier cash flows, longer life assets, or improvement in profitability after a period of weaker earnings. With the firm only recently becoming profitable and reporting annual net income of NZ$130.0m on NZ$3,883.0m of revenue, that ratio is being calculated off relatively thin earnings.

A P/E of 111.4x is very high compared with both the estimated Fair P/E of 35.4x and the global renewable energy industry average of 15.2x. That suggests the market is paying a heavy premium to today’s earnings level. It could also mean the multiple may move closer to the fair ratio over time if profit growth does not keep pace.

Still, the high P/E leaves Meridian Energy exposed if earnings soften or if investors begin to question paying a premium for relatively modest net income.
