Spark FY23 NPAT up 177% on one-off proceeds as operating cash flow slipped

What changed

Reported revenue rose 20.7% to NZD 4.5b, EBITDAI rose 49.7% to NZD 1.7b, PBT nearly doubled (+98.3% to NZD 1.2b) and NPAT almost tripled (+176.8% to NZD 1.1b). Management attributes the step-up in reported numbers to one-off proceeds (described in the release as "one-off proceeds from technologies in the second half"), with adjusted revenue, EBITDAI and NPAT also in growth but at a much more modest pace. Mobile remained the dominant segment at NZD 1.5b (32.7% of revenue) with a high, stable margin. Operating cash flow fell 4.9% to NZD 800.0m despite the earnings jump, and capex stepped up to NZD 515.0m (11.5% of revenue, vs 11.0%). Gross borrowings fell by NZD 474.0m to NZD 1.1b, taking net debt/EBITDAI to 0.55x from 1.27x. Total FY23 dividend was 27.0 cps (final 13.5 cps, +8.0%), up from 25.0 cps.

What matters

• Tax, not operations, drives most of the NPAT headline. PBT grew 98.3% while NPAT grew 176.8%, a 78.5pp gap explained by the effective tax rate collapsing from 29.4% to 1.5%. PBT is the cleaner operating read, and even that figure is inflated by the one-off proceeds flagged in management's own commentary.
• Cash conversion deteriorated materially. OCF/EBITDAI fell from 73.1% to 46.5%, and OCF itself declined NZD 41.0m year on year even as reported EBITDAI rose by NZD 572.0m. That is the single clearest sign that a large slice of the reported earnings uplift is non-cash or non-recurring.
• Balance sheet is genuinely stronger. Gross debt down 31.1%, equity up 31.5%, net debt/EBITDAI halved to 0.55x. This is the most durable positive in the release, though EBITDAI itself is inflated by the one-offs so the ratio flatters.

Expectations

Management states FY23 delivered to guidance, with free cash flow (company-defined, NZD 489.0m) "towards the upper end" of aspiration versus NZD 296.0m prior. No forward quantified target was parsed from the release. Shape-wise, HY23 captured 60.5% of full-year EBITDAI and 73.7% of full-year NPAT, meaning the second half was materially weaker on the bottom line — consistent with the interim commentary that adjusted EBITDAI and NPAT declined in H1 on broadband/cloud margin pressure, and that the reported growth narrative leans on one-off proceeds booked in 2H. The release supports an "in-line to guidance" read but does not support extrapolating the 49.7% reported EBITDAI growth or 176.8% NPAT growth forward.

Quality of result

Low-to-moderate. The durable components are mobile performance (revenue up, margin ~67% stable), lower net debt, improved working capital (receivable days 33.3 vs 36.4; inventory days 6.4 vs 10.5), and an 8.0% dividend increase comfortably covered (NPAT payout 44.5% vs 114.2% prior). Against that, three features point to timing- or balance-sheet-assisted earnings: the explicit one-off proceeds called out by management; the 27.9pp drop in effective tax rate; and cash generation moving in the opposite direction to reported profit. ROE of 58.5% (vs 27.8%) looks strong but is distorted by the same one-off earnings inflating the numerator.

Unresolved

• Quantum and nature of the "one-off proceeds from technologies" — the release references them qualitatively but the excerpts contain no reconciliation between reported and adjusted revenue/EBITDAI/NPAT.
• Why the effective tax rate dropped to 1.5% and whether any portion is structural versus one-off (e.g., tax treatment of the disposal gain).
• Adjusted (underlying) revenue, EBITDAI and NPAT growth rates are referenced but not quantified in the supplied text, leaving the underlying trajectory ambiguous — particularly given the interim commentary flagged adjusted EBITDAI and NPAT declines in H1.
• Free cash flow as stated (NZD 489.0m) does not reconcile to OCF minus capex (NZD 285.0m) from the extracted lines, so the FCF definition and bridge are unclear.
• Forward capital-return intent beyond FY23, given prior-year language about returning up to NZD 350m to shareholders.

This briefing cannot assess the adjusted/underlying earnings trajectory or the specific composition of the one-off proceeds, because the supplied excerpts do not contain a quantified non-GAAP reconciliation or disposal-gain schedule.
