Aircraft engine, defense, and power systems manufacturer Rolls-Royce ($RYCEY@UK) suffer as air travel dips during the COVID-19 pandemic. As a result, the company’s largest shareholder, Causeway Capital Management, wants fresh ideas in the boardroom after the appointment of Anita Frew as the first woman to lead the company. With Rolls-Royce shares trading at just under $2 per share, investors want to see the company tackle decarbonization and decreased demand for its aircraft engines.
