This includes a number of recent approaches. WBHO also confirms that it has received an unsolicited, indicative, non-binding and conditional proposal from a major international construction and civil services company to acquire WBHO’s 88% interest in Probuild (Indicative Proposal). The Indicative Proposal is subject to a number of conditions, including satisfactory completion of a due diligence and entry into a mutually agreed Share Sale Agreement. WBHO is currently in discussions with the third party in relation to the Indicative Proposal. The Company’s objective is to maximise value for its shareholders and as such the WBHO Board is carefully assessing recent approaches. The WBHO Board notes that there is no certainty that a binding proposal will be forthcoming and what the final terms of such a proposal might be. Alongside current discussions related to the Indicative Proposal, WBHO has conducted, and is continuing to asses, all potential options for Probuild to ensure that shareholder value is maximised. Notwithstanding current uncertainty in relation to COVID-19, WBHO remains optimistic about the long- term fundamentals of Probuild and its longer-term growth prospects in the Australian market. Investec Bank Limited (financial adviser and JSE sponsor), King & Wood Mallesons and Bowmans (legal advisers) have been appointed as WBHO’s advisers with respect to the current Indicative Proposal. Shareholders do not need to take any action in response to the Indicative Proposal and WBHO will continue to inform the market on any further developments in accordance with its continuous disclosure obligations.
