Singtel Group, a publicly owned company headquartered in Singapore, founded in 1879, employs approximately 8,140 individuals. The company reported $10.9B in revenue as of 2025. Functioning primarily in telecoms, the group operates Singtel Singapore, Optus in Australia, and NCS, in addition to several other subsidiary and group companies and various investments in telcos across Asia and Africa.
On July 31, 2026, the Australian Communications and Media Authority (ACMA) initiated legal proceedings against Optus, a wholly owned Australian subsidiary, regarding a Triple Zero emergency call service outage from the previous year. This September 18 outage, which occurred across parts of NSW, South Australia, Western Australia, and the Northern Territory, adversely affected users' ability to connect to emergency services, with two deaths linked to the incident. Also on July 31, Singtel shares closed 3.1% lower at S$4.44, down S$0.17, as the stock traded ex-dividend, coinciding with ongoing developments concerning a potential stake sale in Optus. Earlier on July 31, Singtel confirmed it was in discussions with multiple parties regarding a potential stake sale in its Australian telecoms unit but stated there was no certainty that these talks would result in a deal.
