- Disclosed assets
- $42M to $175M
- Disclosed liabilities
- $9.5M to $46M
A net worth for Markwayne Mullin cannot be computed from this filing: values are given as ranges, some items carry no value, and a home kept for personal use is not reported.
- Disclosed assets:
- as ranges on 255 line items, plus 29 without a dollar value
- Disclosed liabilities:
- as ranges on 6 line items
These are the lower and upper bounds of the ranges on the filing, not a market valuation. Assets and liabilities are shown separately and are never netted into a net worth. How these bands are read
The form lists each debt over $10,000 owed at any time during the period it covers, including one repaid before the period ended. A few kinds are left off, such as a debt to a close relative.
Kept since Aug 27, 2026. Federal law generally requires a filing to be destroyed six years after it was received, unless it is needed in an ongoing investigation.
