Tesla (TSLA) announced that Robyn Denholm has been appointed as chair of its board, effective immediately. "So that she will be able to devote her full attention to the Tesla Chair role, Robyn will be leaving her role as CFO and Head of Strategy at Telstra, Australia's largest telecommunications company, once her six-month notice period with Telstra (TLSYY) is complete," the company said in a statement. Robyn will be serving as Tesla Chair on a full-time basis.

The company added, "To ensure a smooth transition during the remainder of Robyn's time at Telstra, Elon will be a resource to Robyn and provide any support that she requests in her role as Chair. Robyn will continue to provide the necessary focus and time to Telstra during the remainder of her time there, and she will also temporarily step down as Chair of Tesla's Audit Committee until she leaves Telstra." Denholm has served on the Tesla Board as an independent director since 2014. "I believe in this company, I believe in its mission and I look forward to helping Elon and the Tesla team achieve sustainable profitability and drive long-term shareholder value," she said.
