Debt refinancing completed, margins reduced

SYDNEY (Tuesday, 31 March 2026) – Centuria Office REIT ( ASX: COF ) is pleased to announce it has refinanced all of its existing debt facilities. This $1 billion refinancing reduces debt margins by c.30bps and extends the weighted average debt expiry from 2.6 years to 4.3 years with no debt expiries until FY29. The refinancing maintains existing covenants and a diverse pool of five lenders.

COF’s all-in cost of debt remains in-line with FY26 earnings guidance.

Belinda Cheung, COF Fund Manager, said “This transaction highlights lenders’ confidence in Australian office real estate, Centuria management and demonstrates their support through competitive margins similar to other property sectors. This has mitigated any near-term refinancing risk in a robust credit market, delivering a strong outcome for COF unitholders as the REIT benefits from lower margins amid increased volatility in the interest rate market.”
