Spark New Zealand HY25: the tax line obscured the operating read

Revenue fell 1.9% versus HY24. The balance of earnings, cash, and balance-sheet direction is the main question. The filing is also judged against FY25 EBITDAI guidance.

What changed

Revenue fell a modest NZ$37m (-1.9%) to NZ$1,939m, masking a far sharper deterioration lower down the P&L. EBITDAI dropped NZ$111m (-20.9%) to NZ$419m, signalling that cost pressure — rather than top-line erosion — is the primary story. PBT collapsed 74% to NZ$59m, and NPAT fell 77.7% to NZ$35m; the effective tax rate also rose to 40.7% from 30.8%, making PBT the cleaner read on operating performance. Operating cash flow eased to NZ$275m from NZ$307m, though capex fell sharply to NZ$228m from NZ$347m, leaving a modest positive pre-lease free cash flow of approximately NZ$47m against a NZ$40m shortfall in the prior half. On the balance sheet, gross borrowings rose NZ$273m to NZ$1,860m, pushing estimated net debt to roughly NZ$1,760m and net debt/EBITDAI to approximately 4.2x from 2.8x. Equity fell to NZ$1,435m from NZ$1,668m. The interim dividend was cut to 12.5 cents per share from 13.5 cents, though full-year guidance of 25 cents per share has been maintained.

What matters

The scale of the EBITDAI miss versus the run-rate required to hit guidance. HY25 EBITDAI of NZ$419m annualises to roughly NZ$838m — well below the revised FY25 guidance range of NZ$1,040m–NZ$1,100m. That implies the second half must deliver NZ$621m–NZ$681m of EBITDAI, a result roughly 1.5× the first-half outturn. The prior-year comparable shows H2 FY24 generated NZ$633m in EBITDAI versus H1 FY24's NZ$530m, so a back-half loading does have precedent — but the magnitude of recovery now required from a lower base is materially larger than historical seasonal patterns alone can explain. Management will need to demonstrate concrete cost savings from the SPK-26 Operate Programme rather than rely on revenue mix shift.

Leverage has moved to a level that constrains flexibility. Net debt/EBITDAI of approximately 4.2x on a run-rate EBITDAI base that may itself be overstated (if H2 does not recover) leaves limited headroom. The Connexa tower-sale proceeds of ~NZ$310m expected in Q3 and the data-centre capital partner process are therefore not optional strategic enhancements — they are near-term balance-sheet necessities. Whether either transaction closes on the expected timeline and at the indicated values materially affects the year-end leverage position.

Dividend sustainability relative to cash generation. The full-year 25 cents per share guidance implies a total distribution that cannot be covered by current pre-lease free cash flow (HY25 FCF covers less than a fifth of the implied annual payout). The dividend is effectively being funded by asset disposal proceeds and balance-sheet capacity rather than recurring free cash flow, which has implications for capital allocation credibility if either transaction is delayed.

Expectations

Management has provided explicit FY25 EBITDAI guidance of NZ$1,040m–NZ$1,100m (revised down from a prior level implied by the release), with capex of NZ$415m–NZ$435m and a full-year dividend of 25 cents per share maintained. Against that framework:

  • The HY25 EBITDAI of NZ$419m implies a very large second-half recovery is required, well beyond what FY24's seasonal shape (H1 contributed 45.6% of full-year EBITDAI) would suggest automatically.
  • Revenue is broadly stable at a run-rate of approximately NZ$3,878m annualised, slightly above FY24's NZ$3,861m, so volume is not the constraint — margin and cost structure are.
  • The Connexa sale (Q3 proceeds ~NZ$310m) and capital partner process are referenced as near-term catalysts. Their completion is embedded in the capital allocation plan but remains contingent.
  • No order-book or forward-work data is disclosed, so the basis for H2 cost recovery cannot be independently verified from the release.

The result does not provide sufficient evidence that H2 recovery is mechanically assured; it relies heavily on cost-programme delivery that was acknowledged as too slow in FY24.

Quality of result

The result has limited durability characteristics in its current form. The EBITDAI margin compression is operating-cost driven rather than revenue-driven, meaning recovery depends on internal execution rather than market recovery. The improved pre-lease FCF (NZ$47m versus -NZ$40m prior) is primarily a function of lower capex spend rather than stronger earnings — capex intensity fell from 17.6% to 11.8% of revenue. OCF-to-EBITDAI conversion actually improved to 65.6% from 57.9%, which is a positive technical signal, but at a much lower absolute EBITDAI base. The elevated effective tax rate of 40.7% (versus a more normal 30.8%) suppresses NPAT relative to PBT and may not persist, but no explanation for the step-up is provided in the extract. Asset disposal (Connexa) and a capital partner search are structural components of the H2 story — these are balance-sheet events rather than recurring earnings improvements. Overall, the quality of the result is weak: earnings are depressed, the partial recovery in cash conversion reflects capital restraint rather than organic improvement, and key H2 assumptions rely on transaction execution.

Unresolved

  • The SPK-26 cost programme is central to the H2 EBITDAI recovery thesis, but the release provides no quantification of savings already realised versus those still expected — the prior year noted benefits would be "largely realised in FY25," which remains untested.
  • The effective tax rate increased from 30.8% to 40.7% with no explanation available in the supplied extracts; if structural, it further suppresses already thin NPAT.
  • The Connexa sale (~NZ$310m Q3 proceeds) and data-centre capital partner process are referenced as expected rather than contracted — the risk of delay or value leakage is not quantified.
  • Net debt as a formal reported metric is not disclosed, making it impossible to confirm the leverage covenants position or headroom under existing facilities.
  • Segment-level disclosure is insufficient in the supplied extracts to assess which product lines (mobile, IT services, data centres) are driving the EBITDAI margin deterioration.

This briefing cannot assess whether the implied H2 EBITDAI of NZ$621m–NZ$681m is operationally achievable, as the release does not disclose the cost-programme delivery schedule, contract pipeline, or divisional margin trajectory required to evaluate that claim independently.
