KEY ANNOUNCEMENTS
Tower (TWR, #40) has lifted its FY25 guidance, now expecting underlying NPAT of $100mln–$110mln, up from $70mln–$80mln, reflecting lower large event costs with only $7mln recorded year-to-date. Customer numbers grew +5% to 318,000, driven by +10% growth in NZ house insurance policies, though GWP growth is revised down to 2–3% from mid-single digits. The management expense ratio is now expected at ~31% due to lower GWP and continued investment, while claims remain in line with expectations. Full-year results will be announced in November.
Ventia Services Group (VNT) has secured a two-year, $100mln extension to its Facility Management Agreement with the City of Sydney, running from January 2026 to January 2028. The deal covers 251 assets, including Sydney Town Hall and Customs House, with services spanning facilities management, maintenance, cleaning, project works and strategic asset management.

CFO Kristen Lie said the agreement supports Napier Port’s growth, transformation and sustainability projects.
