Is this Michael R Splinter’s net worth? No. A Form 4 reports the shares an insider owns in one company after each transaction, directly or through trusts and entities. It says nothing about cash, other investments, property or debt, options not yet exercised are not counted here, and a holding reported some time ago may have changed without a new filing. The value is shares times the last stored close, not a price anyone received. Sources: the filings listed below, each linked to EDGAR. Compare with the biggest insider stakes.
1 purchase disclosed. $1,000 placed after each of the 1 purchases disclosed since 2025-11-14 would be worth $1K today ($1K put in); the same in the S&P 500 (SPY): $1K.
Not ranked: fewer than 10 purchases measured at 90 days. The middle of the 82 ranked insiders is −5.5 pts (median, against the S&P 500).
Equal weight counts every purchase once; by size counts it for its disclosed dollars. Both are measured from the first close after it was reported. Past results describe the past, not a forecast. How this is measured · Leaderboard
