AIA: EBITDAF up 64% but capex doubles to NZ$451.5m, FCF at -NZ$242.4m

What changed

Revenue rose 53.1% to NZ$440.5m and EBITDAF rose 64.1% to NZ$310.2m, with operating profit almost seven-fold higher at NZ$203.2m. PBT swung from a NZ$1.5m loss to NZ$170.1m; NPAT reached NZ$118.7m versus NZ$4.8m. Operating cash flow improved 49.0% to NZ$209.1m, but property, plant and equipment additions more than doubled to NZ$451.5m, producing free cash flow pre-lease of -NZ$242.4m against -NZ$64.8m in HY23. Gross borrowings lifted 38.5% to NZ$2,231.4m and cash fell to NZ$57.9m, leaving net debt near NZ$2,173.5m. An interim dividend of 6.75 cents per share was declared after none in HY23.

What matters

  • Operating leverage is real but the tax line flatters the headline growth rate. PBT growth of about NZ$171.6m is the cleaner operating read; the NPAT comparison is distorted because HY23 carried a NZ$6.3m tax benefit on a small pre-tax loss, while HY24 bears a normalised 30.2% effective rate.
  • The funding gap is widening. Capex equated to 102.5% of revenue (HY23: 71.2%), and operating cash flow covered less than half of it. With the dividend reinstated at a payout of 83.9% of NPAT but unfunded by internal cash, the balance between infrastructure investment, dividends and debt capacity is the central tension in this release.
  • Leverage optics improved even as absolute debt rose. Net debt/EBITDAF fell to roughly 7.0x from 8.2x, driven by earnings recovery rather than deleveraging; gross borrowings are up NZ$620.3m year on year.

Expectations

No quantified target or forward-work backlog is disclosed in the extracted material, so run-rate against guidance cannot be tested. HY24 revenue annualises to NZ$881.0m, roughly 40.8% above FY23's NZ$625.9m, though FY23 was second-half weighted (HY23 was only 46.0% of full-year revenue and 11.1% of NPAT). Management's own commentary flags that growth "may slow over the second half" as the local aviation industry faces capacity constraints, which argues against simple annualisation of the HY24 figures.

Quality of result

The earnings step-up looks genuinely demand-driven, consistent with continued international travel recovery, and EBITDAF margin expanded to 70.4% from 65.7%. However, quality indicators are softer than the headline. Cash conversion (OCF/EBITDAF) fell to 67.4% from 74.2%. Receivable days stretched to 21.3 from 18.0, with trade debtors up 81.1% against 53.1% revenue growth – a working-capital drag that partially offsets earnings quality. The dividend is not covered by free cash flow on either a pre- or post-lease basis and is being funded on balance sheet. EBITDAFI also excludes fair-value adjustments and associates, and no full non-GAAP reconciliation was extracted, limiting visibility into non-recurring items.

Unresolved

  • Current-period segment mix (Aeronautical, Retail, Property) is not in the extract, so the margin contribution from the highest-margin Retail/Property segments cannot be verified for HY24.
  • The composition of the NZ$620.3m year-on-year increase in gross borrowings, and how much of the NZ$451.5m capex relates to the terminal redevelopment versus recurring maintenance, is not disclosed here.
  • Underlying profit (referenced in FY23 commentary) is not quantified for HY24 in the extract, so the gap to reported NPAT is unknown.
  • No formal FY24 guidance range was provided, leaving management's "may slow" comment qualitative.

This briefing cannot assess passenger volume trends, aeronautical pricing outcomes, or the specific phasing of the capex programme, as none of those were included in the extracted data.
