Spark New Zealand (SPK) / FY21

Spark hits EBITDAI guidance but NPAT falls 10.1% on higher tax rate

Headline EBITDAI growth of 1.0% to $1,124m masks a 4.2% PBT decline, softer cash conversion, and a dividend payout ratio climbing to 60%.

What changed

Revenue slipped 0.8% to $3,593.0m as the loss of mobile roaming revenue dragged the Voice segment down 21.2% to $308.0m. EBITDAI rose 1.0% to $1,124.0m, which management describes as the top end of guidance. Below EBITDAI, however, PBT fell 4.2% to $553.0m and NPAT fell 10.1% to $384.0m, with the effective tax rate stepping up from 26.0% to 30.6%. Operating cash flow declined 5.0% to $858.0m and capex eased modestly to $354.0m. Net debt improved to roughly $1,331.0m from $1,419.0m, taking net debt/EBITDAI to about 1.18x from 1.27x. The final dividend was held at 12.5 cents, taking the full-year dividend to 25.0 cents.

In the segment mix, Mobile grew to $1,311.0m (36.5% of revenue) and Managed data/networks rose to $282.0m, while Voice shrank to 8.6% of revenue from 10.8%. Cloud, security and service management remained the highest-margin segment at roughly 80.8% contribution margin.

What matters

  • Tax rate is doing the damage below EBITDAI. PBT growth of -4.2% is the cleaner operating read; the additional 5.9pp drop to NPAT is tax-driven rather than reflecting a disclosed one-off or discontinued operation. Investors should not anchor to the -10.1% NPAT move as the operating signal.
  • Cash conversion weakened. OCF/EBITDAI fell from 81.1% to 76.3%, and receivable days extended from 29.1 to 31.9. EBITDAI "growth" of 1.0% therefore did not translate into cash; pre-lease free cash flow is implied at roughly $504.0m vs $529.0m prior, even with capex $20.0m lower.
  • Leverage and capital returns are moving in opposite directions. Net debt fell and leverage improved to 1.18x EBITDAI, yet the payout ratio against NPAT climbed to 60.4% from 53.9%. The dividend remains covered by pre-lease FCF (46.0% payout), but the cover is narrower than 12 months ago.

Expectations

No numeric forward-work or multi-year target was extracted, and management limits itself to saying FY21 "delivered to guidance." The interim context is informative: HY21 was 50.0% of full-year revenue but only 44.7% of EBITDAI and 38.5% of NPAT, so the second half carried disproportionate profit. That shape implies operating leverage returned in H2 as cost discipline landed, rather than a broad top-line recovery — revenue growth was still negative for the full year. Against the single disclosed marker (EBITDAI at the top of guidance), the release supports management's claim; it does not, in isolation, support a read on FY22 revenue or margin trajectory.

Quality of result

The earnings quality is mixed. EBITDAI growth was delivered through cost discipline against a shrinking revenue base, and the drivers flagged — roaming loss and voice decline — look structural rather than timing. Segment mix modestly helped: share rotated from Voice into Mobile, Managed data, and Cloud/security, all higher-margin lines. Working against durability, cash conversion deteriorated by roughly 4.8pp and receivable days lengthened, so a portion of the EBITDAI result sat in the balance sheet rather than in cash. ROE also slipped from 28.8% to 25.6%. The $433.0m free cash flow figure cited by management is the cleanest single data point supporting the dividend, but it is a company-defined measure without a full reconciliation in the extracted material.

Unresolved

  • Why did the effective tax rate rise by roughly 4.6pp, and is 30.6% the new run-rate or a one-period step-up?
  • How much of the 1.0% EBITDAI growth is one-off cost-out versus a sustainable lower cost base, given revenue is still contracting?
  • What is the path for roaming recovery, and how sensitive is FY22 EBITDAI to border-reopening timing?
  • What drove the 2.8-day extension in receivable days, and does it reverse in H1 FY22?
  • Is the 60.4% NPAT payout ratio a deliberate target or a function of a depressed NPAT denominator?

This briefing cannot assess valuation, competitive positioning versus peers, or forward guidance, because no target, multiple, or numeric outlook was supplied in the extraction.
