I was awarded 100,000 RSUs with a double trigger event for IPO & vesting. After both happened, I still had a 210 day lockup period which ended on 12/10/20. My company set the taxable amount on my shares at close of market on 12/9/2020 when the stock price was $47 per share. The company then executed a sell to cover that took until 12/16/2020 to complete during which time the share price dropped to $39 per share by the time shares were received (made available to me) on 12/17/2020. This resulted in an over taxation amount of $8 per share so my W-2 stated a taxable amount that was $800,000 over the actual amount I received. How should I address a situation where the sell to cover took much longer than expected and the share price dropped 17% during the sell to cover. I had no access to the shares to do anything until the morning of 12/17 when they showed up in my account. Please advise.
