Revenue halved to NZ$281.1m and operating EBITDAFI fell 34.1%, with cash conversion at an unprecedented 8.6% as receivables ballooned.

What changed

Reported net profit after tax rose 139.4% to NZ$464.2m and EBITDAFI rose 173.4% to NZ$711.9m, yet revenue fell 50.4% to NZ$281.1m and management's own operating EBITDAFI measure fell 34.1% to NZ$171.5m

The release explicitly states underlying profit swung NZ$230.3m to a NZ$41.8m loss (versus a NZ$188.5m underlying profit in FY20). The reported earnings uplift therefore reflects fair-value and revaluation movements rather than trading performance.

Cash conversion collapsed to 8.6% of EBITDAFI (FY20: 67.5%), which Annolyse's historical baseline classifies as unprecedented low against a four-period mean of 63.5%. Operating cash flow fell to NZ$61.0m from NZ$175.8m. Net debt/EBITDAFI fell to 1.8x from 5.3x, but this reflects an NZ$1.3bn equity injection, with total equity rising 19.5% to NZ$7.9b and gross borrowings down 35.1% to NZ$1.4b.

What matters

The reported P&L is non-cash. EBITDAFI of NZ$711.9m sits NZ$540m above the operating EBITDAFI management quotes (NZ$171.5m), and the historical baseline flags the 252.3% EBITDA margin as unprecedented high against a 80.8% four-period mean

  • This matters because the +139.4% reported NPAT and +149.8% PBT growth are revaluation outcomes; the operating business lost money once asset gains are stripped out.
  • Cash quality deteriorated sharply alongside working-capital absorption. OCF/EBITDAFI of 8.6% is unprecedented low versus a 63.5% mean, debtor days jumped to 31.0 (mean 8.3, also unprecedented high), and operating working capital absorbed NZ$10.5m versus a +NZ$3.5m average build. With revenue more than halved, receivables of NZ$23.9m grew 75.7% — the cash conversion problem is concentrated in a small base, but it directly weakens the read on reported earnings.
  • Balance sheet was repaired by equity, not earnings. Net debt/EBITDAFI of 1.8x is unprecedented low against a 3.78x mean, driven by the equity raise rather than free cash generation. Pre-lease FCF was still NZ$-134.7m, and no dividend was declared, preserving liquidity while the capital structure is reset.

Expectations

No forward target was supplied

The HY21 versus FY21 shape is informative: the first half delivered 46.8% of full-year revenue but only 12.4% of EBITDAFI and 6.1% of NPAT, implying an NZ$623.7m second-half EBITDAFI swing — almost entirely revaluation, since implied 2H revenue of NZ$149.6m cannot support that earnings level operationally. This matters because the second-half "improvement" is overwhelmingly mark-to-market, not a demand recovery, and the result therefore does not support extrapolating an operating turn from headline trajectory.

The release flags a new Net Zero pathway and signals positioning for demand return, but provides no quantified FY22 anchor against which this result can be benchmarked.

Quality of result

Earnings quality is poor

Three indicators line up: (i) reported NPAT rose while management's own underlying measure fell to a loss; (ii) cash conversion of 8.6% is the weakest in the supplied historical window; and (iii) free cash flow before leases remained negative at NZ$-134.7m despite capex being cut 54.8% to NZ$195.7m. Capex intensity at 69.7% of revenue underlines that the asset base is being maintained against a depressed top line, not that spending discipline has structurally improved.

The leverage improvement is real but balance-sheet-assisted: equity rose NZ$1.3bn while EBITDAFI was inflated by revaluations, so the 1.8x ratio overstates underlying deleveraging capacity. The effective tax rate of 5.9% (versus 1.8% prior) and the 10.4 percentage-point gap between PBT and NPAT growth is a secondary distortion compared with the much larger revaluation effect; PBT growth of 149.8% is itself the wrong operating read, because both PBT and EBITDAFI are dominated by non-cash items this year.

Unresolved

Open questions

What was the dollar value of property and investment fair-value movements included in reported EBITDAFI, and how much of the NZ$540m gap between reported and operating EBITDAFI does that explain?
Why did debtor days rise to 31.0 from 8.3 against a halved revenue base — is this concentrated in deferred aeronautical charges or rent relief that may not convert to cash?
How does management expect the NZ$41.8m underlying loss to bridge back to profitability, and what passenger volume assumptions sit behind that path?
Will the strengthened 1.8x leverage ratio be defended through the recovery, or is it explicitly a buffer for further capex on aeronautical infrastructure?
When is dividend resumption contingent on — positive underlying profit, positive pre-lease FCF, or a stated leverage ceiling?

This briefing cannot assess passenger-volume recovery trajectories, regulatory aeronautical pricing outcomes, or the durability of property fair-value gains that drove the reported result.
