PBT up 52.9% but operating cash fell 10.8% as capex hit $502.3m

Earnings leverage on rising traffic is real, but a widening negative free cash flow and a trimmed dividend show the build cycle is still in charge.

What changed

Revenue rose 13.5% to $499.9m and EBITDA climbed 29.9% to $403.1m, with operating profit up 49.6% to $303.9m. PBT grew 52.9% to $260.0m and NPAT 57.8% to $187.3m, aided modestly by a lower effective tax rate (28.0% vs 30.2%). Aeronautical contributed ~49.7% of disclosed segment revenue at a ~74.8% implied result margin, with Retail (~27.7%) and Property (~18.9%) making up the balance.

Against that P&L strength, operating cash flow went the other way, falling 10.8% to $186.6m. Capex rose to $502.3m from $451.5m, pushing free cash flow before leases deeper into deficit at –$315.7m (from –$242.4m). Cash on hand jumped to $464.4m from $57.9m while gross borrowings rose to $2,463.4m, and total equity expanded $1,603.9m to $10,046.8m — consistent with a material equity injection rather than organic build. The declared interim dividend was cut to 6.25c from 6.75c.

What matters

  • Earnings quality is mixed. PBT +52.9% is a clean operating read, but OCF/EBITDA collapsed to 46.3% from 67.4%. Trade receivables rose 59.5% to $82.3m and receivable days stretched to ~30.0 from 21.3. The P&L leverage from traffic recovery is real; the cash translation this half was not.
  • Leverage optics improved, but via the balance sheet, not cash generation. Net debt fell to ~$2.0bn from ~$2.17bn and net debt/EBITDA eased to ~5.0x from ~7.0x. That move is driven by the cash build (+$406.5m) funded alongside $1.6bn of equity growth, not by free cash flow, which remains materially negative.
  • Capital return is being rationed. The interim dividend was reduced 7.4% per share despite NPAT rising 57.8%, implying a payout of ~51.9% of NPAT versus 83.9% a year ago. With capex at ~100.5% of revenue, the board is visibly prioritising the infrastructure program over distributions.

Expectations

No quantified earnings, cash flow or capex guidance was provided in the excerpts, and no medium-term target was disclosed, so run-rate versus target cannot be assessed. Shape context is distorted: FY24 NPAT of $5.5m was depressed by a weak H2, so the HY24→FY24 split is not a useful seasonal anchor for NPAT. On the top line, annualising HY25 revenue gives ~$999.8m, about 11.7% above FY24's $895.5m, and HY24 was ~49.2% of full-year revenue, suggesting the second half is typically similar in scale rather than materially stronger.

Quality of result

The operating result looks largely durable: segment margins in Aeronautical (~74.8%), Retail (~80.1%) and Property (~75.3%) are consistent with operating leverage on recovered volumes rather than one-off items, and no non-recurring gains were flagged. The below-the-line picture is weaker. Cash conversion deteriorated materially, with OCF/EBITDA down ~21 percentage points and receivable days up ~8.7 days, indicating working-capital drag rather than underlying cash strength. The improvement in net debt/EBITDA is genuine but is supported by the equity-funded cash build, not by free cash flow, which remains deeply negative at –$315.7m pre-lease. Non-GAAP measures also shifted between periods (EBITDA this half versus EBITDAFI/EBITDAF prior), and a full reconciliation bridge was not provided.

Unresolved

  • What drove the $30.7m increase in trade receivables and the jump in days outstanding — timing, customer mix, or a change in credit terms?
  • What is the peak capex run-rate and the expected free-cash-flow inflection point for the current development program?
  • What was the composition of the ~$1.6bn equity increase, and how does management intend to service the enlarged share count against a reduced interim dividend?
  • Is the lower effective tax rate of 28.0% a repeatable outcome or period-specific?
  • How do aeronautical pricing and regulatory settings evolve alongside the capex program?

This briefing cannot assess valuation, market reaction, or management's unstated medium-term financial targets, as none were disclosed in the provided excerpts.
