Mercury NZ (MCY) / FY24

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

What changed

Revenue rose 25.4% to $3,424m but EBITDAF advanced only 4.3% to $877m, opening a roughly 21 percentage-point gap between top-line growth and the issuer's primary earnings measure

Headline NPAT jumped 181.6% to $290m and PBT rose 192.3% to $415m, but those steps follow an FY23 that was depressed by adverse fair-value and finance-cost movements; EBITDAF is the cleaner read for this gentailer.

Operating cash flow grew 5.9% to $612m, broadly in line with EBITDAF, while trade debtors rose 41.1% to $508m and receivable days lengthened to 54.2 from 48.1. Operating working capital absorbed $180m. Capex held at $296m, net debt edged up to roughly $1.9b, and net debt to EBITDAF was essentially unchanged at 2.16x.

What matters

Operating leverage went the wrong way

  • Revenue grew over six times faster than EBITDAF, consistent with the company's commentary that electricity price pressure is expected to persist. For an integrated gentailer, that gap signals higher wholesale and customer-supply costs absorbing most of the revenue uplift, so the headline revenue figure overstates the underlying earnings story.
  • NPAT growth is largely an accounting recovery. PBT and NPAT moved 192.3% and 181.6% respectively, but FY23 NPAT was already disclosed as down 78% versus FY22 on fair-value movements. The +10.7pp gap between PBT and NPAT growth reflects a higher effective tax rate (30.1% versus 27.5%), so reported profit growth flatters durable performance.
  • Payout ratio versus pre-lease FCF is 57% based on the source-backed deterministic derivation.

Expectations

No stated FY24 EBITDAF target was carried forward in the supplied material, although the HY24 release referenced a lifted FY24 EBITDAF guidance of $880m; the reported $877m essentially met that mark

FY25 ordinary dividend guidance of 24.0cps is a modest 3% step on FY24 and signals management is pacing distributions against ongoing cost pressure rather than the headline NPAT recovery.

The release does not supply forward EBITDAF guidance in the supplied excerpts, and management explicitly flagged that electricity price pressure is expected to continue. That matters because the FY24 margin shape — strong revenue, modest EBITDAF — leaves little room for further input-cost drift before earnings stall.

Quality of result

EBITDAF growth of 4.3% is the durable signal; the 181.6% NPAT step is not

The prior comparable was distorted by fair-value and finance items, so PBT and NPAT growth read as normalization rather than operating progress, and the higher current effective tax rate of 30.1% absorbed some of the rebound. ROE of 6.0% (versus 2.1%) sits in the same recovery-from-base category.

Cash quality is mixed. OCF-to-EBITDAF of 69.8% is broadly in line with the prior 68.7%, so cash conversion did not deteriorate against the issuer's primary earnings measure. However, trade debtors absorbed $148m and operating working capital expanded by $180m, so the cash result was assisted by holding capex flat at $296m rather than by tighter collections. FCF-to-NPAT of 162.1% looks healthy, but it primarily reflects depreciation and the still-low NPAT denominator rather than over-earning on cash.

Unresolved

Open questions

Why did EBITDAF grow only 4.3% on a 25.4% revenue lift, and how much of that gap is structural cost pressure versus customer mix?
What drove the $148m increase in trade debtors, and is the longer 54-day receivable cycle a customer-credit issue or a wholesale settlement-timing effect?
How does management reconcile a 23.3cps ordinary dividend at 111.8% of NPAT with FY25 guidance of 24.0cps, given net debt nudged higher?
What is the FY25 EBITDAF expectation now that the integration of the acquired retail business is complete, and what cost-recovery levers remain available?
Why did the effective tax rate rise to 30.1% from 27.5%, and is that the run-rate going forward?

This briefing cannot assess hydrology, hedge book position, customer churn, or wholesale price assumptions underlying forward earnings because none of those operational inputs are disclosed in the supplied material.
