Record HY26 lifts NPAT 46.6% on cargo and smelter recovery

Both rates sit well outside the company's historical baseline: revenue growth of 17.5% compares with a four-period mean of 6.2% (range -0.2% to 16.1%), and NPAT growth at the upper edge of a wide -41.1% to 89.8% range that reflects the volatility of recent periods. The release attributes the step-up to record interim cargo volumes (1.99 million tonnes, up 17.8%), the recovery of NZAS Tiwai smelter activity to normal levels, and stronger container throughput.

PBT rose 44.4% to NZ$11.7m and EBITDA reached NZ$15.3m, while ROE improved to 12.1% from 9.5% — at the top of the four-period 5.2%–12.1% range. Despite the P&L strength, operating cash flow was only NZ$7.6m and free cash flow eased slightly to NZ$5.1m, with cash on hand falling to NZ$2.4m from NZ$6.1m at FY25.

• Cargo volumes rose 17.8% against revenue growth of 17.5%, meaning the lift is essentially volume-led with the smelter normalising. That makes the result less about structural pricing power and more about a cyclical activity recovery; the durability question is whether smelter-related and bulk cargo trends hold into HY27.
• Cash conversion lagged the earnings step-up. OCF/EBITDA of 49.9% and FCF/NPAT of 60.3% are modest given a "record" P&L, and the company itself notes a slight reduction in operating free cash flow despite the stronger operating result. With capex at 7.5% of revenue (NZ$2.6m, up NZ$0.7m on HY25) and contract liabilities of NZ$2.3m on the balance sheet, timing items are doing some of the work.
• Capital allocation has tightened relative to history. The interim dividend rose to 8.5cps from 7.5cps (+13.3%), but the implied payout ratio of 26.4% of NPAT is below the company's historical baseline (mean 42.7%, range 33.5%–64.7%). Coverage from FCF is 43.7%, leaving a buffer that — combined with elevated total assets of NZ$113.1m versus the historical mean of NZ$98.7m — points to capital being retained for the channel deepening and related capex programme.

The supplied seasonality shape suggests the second half is normally heavier: HY25 represented 46.8% of FY25 revenue and 43.2% of FY25 NPAT, implying an FY26 trajectory above FY25 if HY26 momentum simply continues. Annualised on the current half, revenue would land near NZ$69.5m versus FY25's NZ$63.3m.

Commentary points to "H2 continuation of cargo trends with some" caveats, and channel deepening "exceeding expectations". The release does not, however, quantify forward work or H2 guidance, so the implied uplift remains a shape inference rather than a stated target.

The single largest swing factor is the return of NZAS Tiwai volumes to normal — a recovery from a depressed prior comparable rather than a new operating gear. Margin metrics support the lift (PBT margin 33.7% versus a four-period mean of 27.2%; NPAT margin 24.5% versus 19.3%), but both sit at the upper edge of the historical range rather than breaking new ground. The effective tax rate of 27.6% is an unprecedented low against a historical 28.6%–29.8% band, modestly flattering NPAT relative to PBT; the gap is small (2.2pp) and does not change the operating read.

The quality concern is cash. FCF of NZ$5.1m covers the dividend (43.7% payout on FCF) but did not grow in line with NPAT, and the cash balance more than halved versus FY25 close. With net debt at NZ$29.1m (1.9x EBITDA) and capex stepping up, the headline NPAT figure overstates the period's incremental cash-generative durability.

This briefing cannot assess forward cargo bookings, contract pricing, or the quantum and timing of remaining channel-deepening capex, none of which are disclosed in the release.
