Biography

TPG started off as a computer retail company, but several acquisitions including the purchase of a mobile spectrum licence, have contributed to its success as a major internet service provider.^[3]

In August 2018, Teoh announced TPG was in discussions with Vodafone Hutchinson Australia about a proposed $13 billion merger.^[4] Teoh's only comment about the proposed merger was that the pricing would be “very aggressive” and that it would bring value to the customer.^[5] It was blocked by the Australian Competition & Consumer Commission on the grounds that it would lessen consumer choice in both the internet and mobile phone markets.^[6] In early 2020 Vodafone and TPG were granted permission by the Federal Court to merge, paving the way for the stalled $15 billion deal to finally proceed.^[7]

In 2016 it was reported that his wife, Vicky, had substantial investments, including Vita Life Sciences Ltd, a pharmaceutical and healthcare company.^[8]
