Tower PBT margin hits unprecedented 23.7% as ROE reaches 29.0%

PBT rose 46.9% to NZ$70.2m on revenue growth of 9.8% to NZ$295.8m, taking the PBT margin to 23.7% — above the historical mean of 6.3% and the prior peak of 17.7%. ROE reached 29.0% versus a historical mean of 3.7% and a prior peak of 11.5%. Reported NPAT grew 38.1% to NZ$49.7m, while management's underlying NPAT was NZ$61.7m; the release attributes the NZ$12m gap to customer remediation provisions and Canterbury over-cap claims from the Natural Hazards Commission.

Operating cash flow rose 63.2% to NZ$57.7m and pre-lease FCF reached NZ$47.8m versus NZ$33.7m. The interim dividend climbed to 8 cents per share from 3 cents. Capex rose 498.7% to NZ$9.9m, lifting capex intensity to 3.3% of revenue from 0.6%.

The 23.7% PBT margin and 29.0% ROE both sit clear of the prior four-period highs (17.7% and 11.5% respectively). For a general insurer, this points to pricing, claims management and investment income aligning at the same time. The forward question is whether all three can hold.

Reported profit understates the underlying read. Management discloses underlying NPAT of NZ$61.7m versus reported NZ$49.7m, with the bridge attributed to customer remediation provisions and Canterbury over-cap claims. The cleaner economic comparison is underlying NZ$61.7m versus NZ$36.6m a year earlier; the reported PBT growth of 46.9% is the cleanest in-period operating read, given the effective tax rate moved only modestly to 29.1% from 32.2%.

Capital return has outpaced cash generation. The 8 cent interim absorbs 63.0% of pre-lease FCF, above the historical mean of 31.3% and the prior range of 18.2%–41.8%. Payout versus reported NPAT, at 60.6%, is more contained but still well above the 31.6% prior-comparable level — a meaningful step-up alongside the previously flagged return of capital.

The HY24 first-half share of FY24 revenue and NPAT was 48.5%, suggesting a moderately second-half-weighted pattern; the current half implies an annualised revenue run-rate around NZ$591.6m if that shape repeats. The release flags continuing over-cap claim notifications from the Natural Hazards Commission, which is the live downside in the underlying-to-reported bridge for 2H25.

The data does not include forward written premium, line-by-line claims trends, or reinsurance pricing for FY26, so the durability of the unprecedented margin cannot be tested against forward indicators in this release.

OCF of NZ$57.7m exceeds reported NPAT, taking FCF-to-NPAT to 96.1%, and pre-lease FCF of NZ$47.8m sits at the upper edge of the historical range (mean NZ$30.2m). The PBT growth of 46.9% versus NPAT growth of 38.1% — an 8.8pp gap — reflects a moderately higher effective tax rate (29.1% versus 32.2%) rather than below-the-line distortion, so the operating step-up is real.

Two qualifications matter for durability. First, capex rose nearly six-fold to NZ$9.9m, dominated by NZ$9.1m of intangibles; recurring capex intensity is now 3.3% of revenue versus an unusually low 0.6% prior comparable, so the FCF strength partly reflects a low base. Second, the unprecedented margin sits on a benign claims environment and pricing actions whose persistence is not contracted; the customer remediation provision and continuing Canterbury claims are a reminder that prior-period book risk can still surface.

This briefing cannot assess underlying claims-cost trends, reinsurance economics, or premium retention, none of which are quantified in the supplied data.
