Revenue fell 7.8% but EBITDAF margin hit an unprecedented 33.1%

This matters because the revenue decline does not signal weaker demand or earnings; it reflects wholesale/retail revenue movements offset by stronger renewable generation and cost discipline (OPEX held at $370m). PBT rose 7.0% to $444.0m and NPAT rose 10.7% to $321.0m, a gap explained by the effective tax rate falling to 27.7% from 30.1%, not a one-off item. Capex jumped to $710.0m (22.0% of revenue, versus 13.9% prior), funding the disclosed $590m hydro refurbishment FID, and second-half NPAT of $301.0m dwarfed the $20.0m first-half figure — an extreme skew typical of gentailer hedge and fair-value timing rather than a shift in run-rate earnings.

PBT growth of 7.0% is the cleaner operating read than NPAT growth of 10.7%, because the improvement is driven by a lower effective tax rate (27.7% versus 30.1%) rather than stronger pre-tax performance. Investors tracking underlying operating momentum should anchor on PBT, not the headline NPAT increase.

Cash generation looks genuine, not working-capital assisted. OCF/EBITDA conversion improved to 71.3% (upper edge of its historical range, mean 66.7%) and pre-lease free cash flow reached an unprecedented $612.0m against a $368.0m mean, while the underlying working-capital movement was negligible at roughly $1m. This means the cash strength reflects real EBITDAF growth and disciplined opex, not a temporary debtor or inventory swing, which supports the case that current cash generation is durable.

Leverage improved even as borrowings rose. Net debt to EBITDA fell to 2.24x from 2.79x despite gross borrowings increasing to $2.5b to fund the capex step-up, because EBITDAF growth outpaced debt growth. However, the dividend payout ratio against NPAT reached 119.2%, meaning the distribution currently exceeds statutory profit and depends on continued strong free cash flow rather than reported earnings coverage.

The extreme first-half-to-second-half skew (first-half NPAT was just 6.2% of the full-year figure) means the interim result is not a reliable guide to full-year shape, and readers should treat the annual cash and earnings figures as the meaningful unit of comparison, not a run-rate off the half.

The heavier capex intensity (22.0% of revenue, up from 13.9%) reflects genuine reinvestment into renewable and hydro assets rather than deferred maintenance catching up, which is consistent with a multi-year build programme rather than a one-off spike. The main quality caveat is capital allocation: a 119.2% NPAT payout ratio is only sustainable if the current EBITDAF margin, which sits well above its historical average, persists; if generation conditions or wholesale pricing normalise, dividend cover would tighten even though cash flow currently looks comfortable.

This briefing cannot assess the underlying hydrology, hedge-position, and generation-mix drivers behind the margin move because that operational detail was not supplied in the extraction data.
