Capex-driven cash burn pushes leverage higher as PBT falls 18.6%

This capex-driven cash outflow is the most material development in the period, occurring alongside a reported profit before tax decline of 18.6% to $450.9m and a net profit after tax decline of 20.4% to $334.7m. Revenue grew 3.1% to $1b, well below the company's own five-year average growth of 24%, partly reflecting lower interest income as cash built from a prior equity raise has been drawn down. Gross borrowings rose 11.3% to $2.8b, lifting net debt/EBITDA to 3.7x from 2.7x. Aeronautical revenue rose to $529.8m, lifting its revenue share to 51.2% from 49.2%.

Capex equalled 103.1% of revenue and pre-lease free cash flow was deeply negative, meaning current infrastructure spending exceeds the cash the whole business generates, funded by added debt rather than internal cash. For an investor, this signals the airport is mid-cycle in a large capital build, compressing cash available for shareholders until spending eases.

Headline profit decline overstates the operating slowdown. PBT fell 18.6% and NPAT fell 20.4%, the cleanest available reads on the reported result, but company disclosure shows underlying profit (which strips fair-value and one-off items) fell only about 0.5% to $309m, indicating revaluation movements rather than the aeronautical, retail or property businesses drove most of the headline decline. All three segments posted revenue growth and stable margins near 74–80%.

Leverage build is funding growth. Net debt/EBITDA rose to 3.7x from 2.7x as gross borrowings grew 11.3% and cash fell 90.2% to $55.4m as prior equity-raise proceeds were largely used. Financial flexibility has narrowed year-on-year, even though the ratio still sits within the company's own five-year range.

The disclosed payout ratio was 72.8% of underlying profit, within the stated 70–90% policy band, and the full-year dividend was held at 13.25 cents per share, matching the prior year, even though the final component eased to 6.75 cents from 7.00 cents. The first half contributed 52.9% of full-year NPAT ($177.0m of $334.7m), implying a smaller second half ($157.7m), consistent with normal seasonal skew rather than a guided outcome, since no forward figure was supplied to test against.

Operating cash conversion improved to 69.5% of EBITDAFI from 67.6%, sitting within the company's own five-year range, so the underlying cash-generating engine is not deteriorating in isolation. The issue is capital intensity: capex rose 13.8% while EBITDAFI rose only 3.3%, so nearly all operating cash, and then some, is absorbed by infrastructure spending rather than converting to free cash for shareholders. That combination of healthy conversion but negative free cash flow means the dividend is currently being funded from a mix of operating cash flow, debt and residual equity-raise cash rather than covered on a free cash flow basis. Total assets rose 5.2% to $14.8b, an unprecedented level against the company's own five-year history, largely reflecting capital under construction rather than yet-realised earnings. This suggests operating durability is intact, but the cash and balance-sheet picture is being actively reshaped by the build cycle.
