Big Technologies chair steps down after shareholder backlash

(Sharecast News) - AIM-listed Big Technologies has announced the resignation of Alexander Brennan from its board following calls from shareholders to oust the non-executive chair.
The company, which makes ankle tags and software for the electronic monitoring industry, has faced fierce criticism following the sacking of former chief executive and founder Sara Murray in March over alleged forgery and the falsification of documents in the lead-up to the company's flotation in 2021.
A general meeting last week saw shareholders holding 52% of active voting rights support the ousting of Brennan, with 26.2% of those voting rights held by Murray.
Big Technologies, which trades under the Buddi brand, said Brennan has now stepped down with immediate effect and will be replaced on an interim basis by non-exec Sangita Shah.
Shareholders want to appoint Jamie Matheson, chairman of Aberdeen Standard Fund Managers, as Brennan's permanent replacement, according to last week's vote.
"Having led the board as Interim Chairman and then Chairman, including during the period of the investigations undertaken by the Company related to the removal of Sara Murray as CEO, Alexander has made the determination that it is in the best interests of all shareholders if a new director, independent of the investigations, were to lead the Company's efforts to resolve the protracted litigation against Sara Murray and associated parties," the company said in a statement.
Last month, Big Technologies said it was looking to expand its claim against Murray and others as part of a strengthened case, but offered mediation with a view to settlement "as an alternative route to what will otherwise be protracted litigation".
