South Port NPAT jumps 89.8% on bulk cargo rebound from weak HY24 base

What changed

HY25 revenue rose 16.1% to NZ$29.6m, and the operating leverage in a port business drove NPAT up 89.8% to NZ$5.8m and PBT up 88.9% to NZ$8.1m. Management attributes the step-up to increased bulk cargo volumes and a rebound in fertiliser imports from an unusually low HY24 base, rather than pricing. Equity grew to NZ$60.9m (+5.3%) on an NZ$108.7m asset base (+1.9%). The interim dividend was held at 7.5 cents per share. Operating cash flow, capex, cash, and gross borrowings were not disclosed for HY25 in the supplied material, so the cash and leverage lines cannot be updated against the FY24 gross borrowings of NZ$43.5m or HY24 operating cash flow of NZ$0.9m.

What matters

• The comparable was unusually weak. HY24 carried only 41.1% of FY24 NPAT and 45.4% of FY24 revenue, reflecting depressed volumes called out in last year's release. Headline growth rates therefore flatter the underlying trend: HY25 revenue annualises to NZ$59.2m, only ~5.4% above FY24 actual revenue of NZ$56.1m.
• Earnings growth is clean at the tax line. Effective tax rate is 28.9% versus 29.3% prior, and PBT growth (88.9%) tracks NPAT growth (89.8%) almost exactly. The result is a volume story, not a tax or one-off story.
• Customer concentration is material and qualitative. NZAS is described as supporting about a third of cargo volume and is only returning to full production by April 2025; the new Meridian energy transfer arrangement is also flagged as significant. These are both positive forward drivers and a concentration risk.

Expectations

No quantified guidance or target was disclosed. Against seasonality, South Port has historically been second-half weighted (HY24 was 41.1% of FY24 NPAT, HY24 operating cash flow was just 6.9% of the full year). If that shape holds, HY25's NZ$5.8m NPAT implies a full-year outcome comfortably above FY24's NZ$7.4m reported NPAT, though the HY24 base was unusually weak and FY24 normalised NPAT was NZ$10.0m. The NZAS potline ramp to full production by April 2025 is a 2H volume tailwind that the release supports qualitatively but does not quantify.

Quality of result

Earnings quality on the income-statement side looks genuine: the PBT/NPAT bridge is tight, the effective tax rate is stable, and no non-recurring items are disclosed in the HY25 release. The bigger quality caveat is what is not in the release — no HY25 operating cash flow, capex, cash, or borrowings figures are provided in the supplied extraction. Given HY24 operating cash flow was only NZ$0.9m and FY24 capex was a substantial NZ$10.3m, cash conversion and leverage direction cannot be verified from this release. The payout ratio on NPAT has fallen from 64.7% to 34.2% simply because earnings doubled against a flat dividend, so the held dividend should not be read as a confidence signal about 2H cash flow.

Unresolved

• What is HY25 operating cash flow, and has cash conversion kept pace with the NPAT jump?
• Where are gross borrowings and net debt after HY24's FY24 capex spend of NZ$10.3m and the NZ$42.0m FY24 net debt position?
• How much of the volume recovery is NZAS-specific versus broad-based, and what is the incremental revenue contribution from the Meridian energy transfer agreement?
• Does management see FY25 normalised NPAT recovering toward the FY24 normalised NZ$10.0m figure, or beyond?

This briefing cannot assess HY25 cash generation, leverage direction, or segment-level profitability because those disclosures are not present in the supplied extraction.
