Serko Guidance Update

Serko Guidance Update Serko Limited (NZX/ASX: SKO) advises that trading performance in the first half has been stronger than anticipated, driven by an acceleration in completed room nights. Serko anticipates that this momentum will continue in the second half, with underlying growth continuing on a seasonally adjusted basis. Serko expects to make a modest upward revision to its current FY27 total income guidance range of $128m-$134m at its 1H27 results on 16 November 2026. Total spend is projected to be towards the middle of the $132m-$140m range. Serko also expects to report positive free cash flow for both the six months ended 30 September 2026 and the FY27 year. At its full year results on 20 May 2026, Serko noted its FY27 guidance range was primarily driven by the timing of booking volumes from the strategic initiative targeting defined US corporate segments. With the initiative in its early stages, Serko does not currently expect it to meaningfully contribute to FY27 total income. Strong momentum in Serko’s core business is now expected to be the primary driver of FY27 growth. Serko will provide a full update, including further detail on the FY27 outlook and progress on its strategic initiatives, at its 1H27 results on 16 November 2026.
