The setup & the reality

FY25 → HY26 Follow-through

The latest result is checked against what the prior briefing said to watch.

Historical setup

What FY25 said to watch

From FY25 EBITDAF fell 10.4% to $786m, missing $820m HY25 guidance

Mercury entered the second half with FY25 EBITDAF guidance of $820m reaffirmed; the implied second‑half EBITDAF of $368m (versus $418m in HY25) was insufficient to meet that bar. The board has guided FY26 ordinary dividend of 25cps (versus 24.0cps declared for FY25), and the release references an "indicative FY30 EBITDAF aspiration" without a quantified path.

The supplied excerpts do not contain FY26 EBITDAF guidance. Without it, the read on whether $786m represents a hydrology low or a new base in a heavier‑capex configuration cannot be settled from this filing alone. The prior FY24 comparable also incorporated the completed Trustpower retail integration, so the year‑on‑year step is not a perfectly clean like‑for‑like.

Open questions

Open questions from FY25

What specific items drove PBT and NPAT to approximately $1m given EBITDAF of $786m — are these fair‑value movements on the derivative hedge book, impairments, or other non‑cash charges?
Why did the effective tax rate fall to 0.0% from 30.1%, and is that a function of pre‑tax mix this year or a recurring feature?
What is FY26 EBITDAF guidance, and on a normal‑hydrology assumption does the $820m FY25 reference point remain the right anchor?
How much of the $437m capex is contractually committed versus discretionary, and where does net debt/EBITDAF peak through the build cycle?
What share of the Fonterra and Visy long‑term agreements is reflected in FY25 revenue versus future periods?

This briefing cannot assess the composition of the gap between EBITDAF and reported NPAT without specific disclosure of the fair‑value, derivative, or other non‑cash items sitting below the EBITDAF line.

Briefing archive

Every published Annolyse briefing for this company appears here in reverse chronological order.

HY26 · Released 24 February 2026

EBITDAF up 28.5% on revenue down 5.2% as margin hit upper edge

NPAT swung from a NZ$67.0m loss to a NZ$20.0m profit, but a 35% capex step-up absorbed most of the operating cash uplift.

Read briefing

FY25 · Released 19 August 2025

FY25 EBITDAF fell 10.4% to $786m, missing $820m HY25 guidance

Dry conditions cut renewable generation 10% just as capex jumped 47.6% and net debt/EBITDAF stepped up from 2.2x to 2.8x.

Read briefing

HY25 · Released 25 February 2025

Mercury NZ EBITDAF margin fell to an unprecedented 23.8% as revenue grew 9.3%

Reported NPAT swung to a $67m loss on below-line items while capex jumped 53% and pre-lease free cash flow fell to $25m.

Read briefing

FY24 · Released 20 August 2024

Revenue jumped 25.4% but EBITDAF rose only 4.3% on margin compression

Headline NPAT growth of 181.6% reflects a fair-value reversal from a depressed prior year, while trade debtors expanded 41.1% and cash conversion

Read briefing

HY24 · Released 20 February 2024

NZ$539m working-capital build dwarfed NZ$17m EBITDAF decline

An unprecedented year-on-year operating working-capital expansion overwhelmed a modest EBITDAF dip and lifted leverage to 4.5x net debt/EBITDAF.

Read briefing

FY23 · Released 21 August 2023

EBITDAF rose 44.8% but NPAT fell 78.0% on a prior-year one-off gain

Operating earnings strengthened on record generation, while a non-recurring prior-period gain distorts the headline net-profit comparison.

Read briefing

HY23 · Released 21 February 2023

EBITDAF up 86% but PBT fell 40% on acquired-swap unwinds

Trustpower's full half and a $65m HY22 hedge exit make this non-comparable, though OCF/EBITDAF conversion at 76.5% is unprecedented in recent history.

Read briefing

FY22 · Released 16 August 2022

EBITDAF up 25.5% but $367m Tilt sale gain inflated NPAT to +232.6%

Cash conversion fell to 60.6% from 73.0% as working capital absorbed $258m and net debt/EBITDAF rose to 3.25x.

Read briefing

HY22 · Released 22 February 2022

EBITDAF fell 17.7% on dry hydrology while reported NPAT tripled

A 5.1% effective tax rate and non-operating gains flattered headline profit even as FY22 EBITDAF guidance was cut to $570m.

Read briefing

FY21 · Released 17 August 2021

FY21 PBT fell 30.2% as EBITDAF dropped 6.3% on a 15.7% revenue lift

Higher revenue did not translate into earnings, leverage edged up to 2.9x EBITDAF, and the NPAT-based payout ratio reached 164.1%.
