WEB held its FY25 results on 27th May 2025, with TTV at A$4.9B +22% YoY (~-2% vs GSe and VA cons), Revenue +1% YoY (+1% vs GSe) and EBITDA of A$121m with 1H25 guidance of A$117-122m.

The broker also highlights that it is becoming more confident in the ASX 200 growth stock delivering on its medium term revenue to TTV margin guidance. It adds:

Re-balancing supply mix to negate Rev margin headwinds require FY26 EBITDA margin investment: Mgmt guided FY26 EBITDA margins of 44-47% (vs prev 48%) on account of investment in hotel contracting headcount in Asia Pacific/Americas regions. We expect sequential improvement into FY27, though remain below 50% mgmt guidance (GSe 48%). With that said, increased investment in direct contracting increases our confidence in medium term 6.5% Rev/TTV margin guidance (GSe FY27/28 ~6.5%).

Reflecting the above, we change our FY26/27 TTV/Revenue ~1% and FY26 EBITDA margin is lowered from 48% to 45.5% (44-47% guidance), resulting in -6% EBITDA revisions. Our valuation methodology is unchanged, but we roll valuation forward to FY27 earnings, marking to market multiple vs peers.
