EBITDAF up 38% and cash conversion hit 70.9%, above CEN's normal range

EBITDAF rose to NZ$354m (from NZ$257m in HY23 per the presentation), a 38% increase driven almost entirely by the Wholesale segment, which contributed NZ$383m in segment result on revenue that jumped to NZ$969m from NZ$422m. Retail revenue grew more modestly to NZ$618m from NZ$568m, but the segment swung to a small loss of NZ$1m from a NZ$1m prior profit, reflecting cost pressure against constrained customer revenue.

Group revenue rose 31.4%, well above the company's historical mean growth rate of 4.2%. PBT moved from a NZ$9m loss to NZ$213m profit, though the percentage change is not analytically meaningful given the near-zero prior base. NPAT of NZ$153m likewise reflects the swing from a negligible prior-period result. Gross borrowings rose NZ$495m to NZ$1.9b, pushing net debt to NZ$1.6b.

The Retail segment's slim NZ$1m loss on NZ$618m revenue signals that margin recovery in the customer-facing business has not kept pace with cost. The 2024 first-half story is essentially a wholesale electricity market outcome; durability depends on hydrology, spot and contract prices, and generation availability — factors outside management control.

Cash conversion at 70.9% is above the company's normal range of 46.7%–61.6%. This lifts OCF to NZ$251m and pre-lease free cash flow to NZ$187m — above the historical mean of NZ$150m but within the wider range. The conversion strength warrants scrutiny: gentailers' working capital is heavily influenced by hedge settlements and fuel cost timing, so a single-half result at this level may partially reflect timing of payables and energy settlements rather than a structural improvement in cash generation.

Net debt rose NZ$384m to NZ$1.6b despite strong operating cash flow, because capex of NZ$262m ran ahead of free cash flow. Net debt / EBITDAF of 4.58x is below the company's historical mean of 5.20x, which is a favourable signal, but the leverage direction is weakening. Gross borrowings of NZ$1.9b represent a 35.4% increase on HY23, and the capex cycle — at 20.1% of revenue — indicates the investment programme remains active.

The FY23 full-year EBITDAF was NZ$460m, and the HY24 result of NZ$354m already exceeds that figure in one half, suggesting the prior full-year was depressed relative to current earnings capacity. Historical seasonality shows Contact's operating cash flow skewing towards the second half — HY23 contributed only 29.1% of FY23's full-year OCF of NZ$395m — so the unusually strong HY24 first-half cash conversion deserves caution when projecting full-year outcomes.

The Retail segment's inability to generate positive contribution despite volume growth is a structural question that the first-half result does not resolve. If wholesale prices normalise in the second half, EBITDAF and free cash flow could soften materially from the HY24 run-rate.

ROE of 5.7% is above the historical mean of 3.2% and sits at a period high in the available baseline.

However, quality caveats apply. EBITDAF is a non-GAAP measure, and for gentailers it typically excludes fair-value movements on energy contracts, which can shift materially between periods. The effective tax rate of 28.2% is within normal range and does not distort the NPAT result in an unusual way this period, but the prior comparable had an effective rate of 22.2%, so reported NPAT should not be used to infer an earnings trend. Cash conversion at 70.9% — while genuinely strong — is above the normal range and may include favourable timing effects in working-capital movements and hedge-settlement flows that are not disclosed in granular form.

This briefing cannot assess the fair-value movement in energy derivatives excluded from EBITDAF, nor the hydrology or generation-capacity assumptions that underpin the Wholesale segment's forward earnings outlook.
