Singtel Stock (SGX: Z74) on 21 December 2025: Latest News, Analyst Forecasts, Dividend Outlook and Key Risks
Singtel shares closed at S$4.54 on December 19 as its Australian unit, Optus, faced renewed scrutiny after a review blamed a September emergency-call outage on firewall upgrade failures and poor incident response. The outage lasted nearly 14 hours, with about 75% of Triple Zero calls failing. Optus accepted 21 recommendations and may face penalties or terminations. Recent separate outages in Queensland and Melbourne also drew attention.
