Tesla blasted Glass Lewis in a letter to shareholders, days after the proxy adviser urged investors to reject a proposed $US56 billion ($84.5 billion) pay package for chief executive officer Elon Musk.

In the letter titled “What Glass Lewis Got Wrong About Tesla”, the electric-vehicle maker said the adviser “omits key considerations, uses faulty logic, and relies on speculation and hypotheticals”. The company urged shareholders to ignore Glass Lewis’ advice and vote in favour of Mr Musk’s compensation package and a company proposal to reincorporate in Texas, from Delaware.
