Macmahon FY26 slides: record results, diversification drives growth

Macmahon’s FY26 results showed record performance with revenue up 8% to $2.6B and underlying EBIT(A) up 11% to $190.1M (7.3% margin), but shares fell 9.34% to $0.898. Despite strong cash conversion (98.4%), free cash flow declined 27% to $103.1M due to higher capex and tax timing, while FY27 guidance implies ~13% revenue and EBIT(A) growth with broadly stable margins around 7.3%. Net debt improved 32% to $111.1M and FY26 dividends rose 47% to 2.20 cents/share, but investors appeared cautious on near-term cash flow and margin/leverage assumptions as FY27 capex is set to rise to ~$266M.

Analysis

This is a cash-flow re-rating, not an earnings problem. The market is telling you that incremental growth now comes with a higher reinvestment burden, so equity value will be tied to free cash flow conversion and equipment intensity more than reported EBIT until management proves otherwise. That usually compresses the multiple first, especially for contractors where the balance sheet looks fine but the fleet has to be refreshed just to keep growth rolling.

The next 1-2 reporting cycles matter more than the headline year. If working capital normalizes and capex stays elevated, reported cash will lag earnings and the dividend signal will not be enough to support rerating; if the capex step-up is truly front-loaded for already-won work, cash should snap back within 6-12 months and the selloff will look excessive. The key falsifier is a sustained rise in net debt/EBITDA or any sign that tender conversion slows while capex remains fixed.

Second-order, the strongest competitors are the ones that can grow without leaning as hard on capital. That favors higher-quality contractors over smaller, more levered peers if the industry starts discounting cash yield over backlog growth. The contrarian miss is that investors may be over-penalizing a growth investment that supports embedded relationships and future M&A optionality, but if civil work keeps diluting group margins, the re-rate stays capped even with decent top-line growth.

Key Decisions for Investors

• Do not chase MCHHF/MALRY on this print; wait 1-2 quarters for free-cash-flow normalization. Add only on a further 8-10% drawdown or if FY27 cash conversion clearly improves versus EBIT.
• If borrow/liquidity is workable, use a tactical short in MCHHF on any relief rally over the next 2-4 weeks; keep a tight stop if management revises capex lower or lifts FCF guidance.
• Relative-value pair for 1-3 months: long NWH.AX / short MCHHF to express the market’s preference for better cash generation over headline growth. Falsify the pair if MCHHF shows a sharp working-capital release in the next update.
• Treat RIO as a monitor rather than a primary trade: if contractor pricing softens further, RIO’s project execution risk improves marginally, but the linkage is too indirect for a standalone position.
