Whittaker's wealth primarily came from his role as a CEO rather than significant stock holdings. His largest personal financial involvement in the company was observed through insider trading, with his reported holdings fluctuating between $4.11 million to $10.61 million from 2019 into 2022, but more recent values showed a decline, indicating a drop to around $3.14 million by 2023. This volatility in holdings reflects the company's performance over time, showing that his net worth was closely tied to the bank's stock performance. After retiring, he maintained a presence in the company, but his personal holdings were mainly in trades rather than in amassed stock ownership.
