Meridian Energy Shares Slip Despite Strong Customer Growth: What Was Reported?

Meridian Energy shares (ASX: MEZ) closed 1.51% lower at A$4.57 on the ASX this week, as markets weighed impressive operational metrics against ongoing wholesale electricity price compression and a scaled-back capital expenditure programme.

The MEZ share price pulled ended both the day and the week with the same decline, now sitting 6.54% lower YTD, and 15.37% down in the past 12 months. This comes despite the company reporting some of its strongest demand and generation figures in recent memory. With a market capitalisation having just dipped below NZ$15 billion on the day, the modest pullback appears to reflect a sentiment recalibration rather than fundamental deterioration, as markets digest the interplay between volume strength and price headwinds. Here’s a closer look at what was in the print.

Price Targets

Operational Strength Across the Board

Meridian’s March 2026 monthly operating report delivered a string of positive volume metrics that underscore the company’s growing market position. Retail sales volumes jumped 11.4% year-on-year, driven by a 27.8% surge in the residential segment. Customer connections climbed 17.7% over the past twelve months to reach 464,985, extending a multi-quarter pattern of robust customer acquisition across residential, small-to-medium enterprise, and large business segments.

Generation volumes told an equally strong story, with March output 30.7% higher than the same month last year. The Waitaki catchment storage sat 39.9% above the previous year’s level at quarter-end, while national hydro storage remained at a healthy 106% of the historical average despite monthly inflows tracking at 74% of normal levels. The strong storage position heading into the Southern Hemisphere winter provides a crucial buffer for seasonal demand shifts.

Demand from New Zealand Aluminium Smelters, a strategically important large industrial customer, continued to recover. Average March load reached 575 megawatts, up from 524MW a year earlier, providing high-volume revenue stability and reducing reliance on costly demand-response arrangements that characterised the drought-impacted prior year.

The Price Headwind

The counterweight to Meridian’s volume success came in the form of sharply lower wholesale electricity prices. Average generation prices in March fell 51.5% compared to the same month in 2025, reflecting the impact of increased renewable generation investment across New Zealand and new system security agreements that have reduced scarcity premiums in the market.

ASX electricity forward prices continued their downward trajectory through the third quarter, a trend Meridian’s management has highlighted in recent presentations. While February 2026 data showed average wholesale and financial contract sales prices at NZ$92.8 per megawatt-hour versus NZ$95.0 a year earlier, the March figures suggest the compression has accelerated. The forward curve weakness reflects greater market confidence in long-term system adequacy as new renewable projects reach completion, but it also caps earnings upside from wholesale-exposed generation.

On the retail side, pricing power has proven more resilient. Average retail contracted sales prices over the eight months to February 2026 rose to NZ$156.1/MWh from NZ$146.8/MWh the prior year, helping to offset some of the wholesale pressure and supporting margin defence in the company’s integrated model.

Capital Discipline Emerges

In a notable shift, Meridian revised its FY26 capital expenditure guidance downward to NZ$280-310 million from a previous range of NZ$330-360 million. The reduction follows a first-half capex spend of NZ$86 million and suggests management is responding to the softer forward price environment by protecting investment returns rather than pursuing growth at any cost.

Year-to-date capital expenditure through the third quarter had surged 182.6% compared to the prior period, driven by substantial investments in Ruakaka Solar, Te Rere Hau, Ruakaka Solar Stage 2, and other renewable projects in the pipeline. The guidance cut implies a more measured approach to deployment in the final quarter, potentially supporting near-term free cash flow generation while slowing the pace of capacity additions.

Operating costs rose 4.9% year-on-year in the third quarter, a moderate increase given the double-digit growth in customer numbers and volumes. Cost-to-supply metrics have normalised sharply from the elevated levels seen during the drought-affected prior year, when demand-response payments and hedging-related expenses spiked. The cost trajectory suggests Meridian is capturing operating leverage as it scales, though persistent inflation in labour and network charges remains an industry-wide headwind.

Balance Sheet and Dividend Support

Meridian’s financial position remains conservative for a utility with long-lived hydro assets. Net debt of approximately NZ$1.7 billion translates to a net-debt-to-EBITDAF ratio of around 1.9 times, down from 2.5 times in June, supported by earnings normalisation and recent capital markets activity including green bond issuance and a committed syndicated facility.

The Board declared a first-half FY26 interim dividend of 6.40 cents per share, up from 6.15 cents previously, maintaining its progressive dividend policy. The dividend increase, delivered even as capex guidance was trimmed, signals management confidence in underlying cash generation and provides support for income-oriented demand for the stock.

Outlook and Strategic Positioning

Markets now face the task of weighing Meridian’s undeniable operational momentum against a structurally softer wholesale price environment.

The 17.7% customer growth rate and rising retail prices support a durable earnings base, while robust hydro storage positions the company well for winter demand. However, the 51.5% collapse in March generation prices and declining ASX forwards constrain upside from the wholesale book and may pressure returns on new renewable investments if the trend persists.

The capex guidance reduction can be read two ways: as prudent capital discipline that protects shareholder returns in a lower-price world, or as a concession that the aggressive growth narrative must be tempered. The answer likely lies somewhere in between, with Meridian shifting emphasis from pure volume growth toward margin defence and balance sheet strength.

Key watchpoints for the coming months include the trajectory of retail customer growth, any further adjustments to capex or operating cost guidance, and management commentary on wholesale hedging strategy at the full-year result. Winter demand patterns and hydro inflows will also be closely monitored, particularly given the company’s strong storage starting position.
