You would need to find the cost basis of the shares that were sold. You can check online for information from the original and spin-off company to see if there is any guidance for the valuation of the new stock.
A company's stock price after completing a spinoff depends on whether any of the spun-off entity was retained. In a complete spinoff, the stock price of the company right before the spinoff should theoretically be equal to the sum of its post-spinoff stock price plus the initial stock price of the spun-off company. Spin-offs are reflected on your brokerage statement, and each broker has different formats.
