Mr. Long, age 59, is a principal of Prime Impact Capital, LLC and previously served as Chief Financial Officer of Western Digital Corporation from 2016 to 2019, as well as Co-Chief Executive Officer and Chief Financial Officer of Prime Impact Acquisition I from 2020 to 2023.

The filing describes Mr. Long's compensation under an employment offer letter. It provides for an annual base salary of $725,000a and a $500,000 sign-on bonus, which is subject to prorated repayment if he leaves before completing two years of employment. He is also to receive a guaranteed annual cash bonus of $500,000, plus an annual performance-based cash bonus ranging from $225,000 to $725,000 with terms still to be determined.
He is eligible for an annual special bonus in restricted stock units. He is expected, subject to Compensation Committee approval, to receive an initial award of 120,000 restricted stock units and an option to purchase 150,000 shares of common stock, each vesting over four years. His employment is at will.
For investors, the key takeaway is a leadership change in the finance function, with the filing identifying the incoming CFO's background and disclosing his compensation package.
