Revenue rose 60.0% but PBT loss widened 22.6% as capex doubled

Operating cash outflow worsened from $14.4m to $17.0m, while capex more than doubled (+106.5%) to $5.0m, taking free cash burn pre-lease to $22.0m for the half. Cash and equivalents stood at $102.9m, down $33.7m from $136.5m a year earlier, and total equity fell 9.4% to $133.8m as accumulated losses absorbed the prior capital base. The headline tension is that strong topline recovery has not yet translated into a narrowing loss; investment intensity, captured by a 26.7% capex-to-revenue ratio, expanded alongside it.

• Revenue rose 60.0% but the PBT loss grew 22.6%, meaning the cost base is still scaling faster than monetised revenue. For an investor, this means the case for Serko rests on the gap closing in coming halves, not on the half just reported.
• Capex intensity stepped up sharply. Capitalised development and PP&E rose to 26.7% of revenue from 20.7%, driving the bulk of the cash drain alongside operating losses. This matters because reported losses already exclude capitalised build costs, so the cash picture is materially worse than the income statement implies.
• Cash runway is finite against the FY25 target. Management reaffirmed FY23 revenue guidance and signalled a return to cashflow-positive operations during FY25. With $102.9m of cash and free cash burn running near $22.0m this half, the path to that target leaves limited room for slippage on either revenue ramp or capex discipline.

Read against that, current annualised revenue of roughly $37.6m supports the reaffirmed FY23 guidance trajectory, but investors should expect the H2 loss and cash burn to be at least as heavy as H1 unless cost growth slows.

No quantified FY23 earnings or cashflow target has been supplied — only the FY25 cashflow-positive aspiration. The release therefore does not support a specific judgement on whether the FY25 milestone is comfortably funded; it supports the narrower observation that current burn is consistent with, but not faster than, that timeline.

However, the gap between PBT loss growth (-22.6%) and NPAT loss growth (-20.2%) is narrow and not driven by a tax distortion (effective rates of -0.7% and -2.8% are immaterial), so PBT and NPAT tell the same operating story.

Cash quality is weaker than the P&L suggests. Operating cash outflow deteriorated $2.5m year on year despite a $0.5m reduction in trade debtors and a sharp fall in receivable days from 60.1 to 32.5, which would normally release cash. That working-capital tailwind was absorbed by underlying operating losses, meaning the cash burn is structural rather than timing-driven. Free cash flow pre-lease of -$22.0m versus an NPAT loss of -$19.7m confirms capex and operating cash outflow together exceed the reported loss, so reported earnings understate the funding requirement.
