Slater's competitive longevity supplied prize money and sponsorship income, while a 23-year Quiksilver relationship gave way to the Kering-backed Outerknown brand. Wave technology and private-company interests may be substantial, but none is valued transparently enough to corroborate the $40 million estimate.
- One net-worth total
- Outerknown ownership and financing are private
- Sponsorship income and prize money are gross earnings
- Wave-company equity, debt and liabilities are undisclosed
- Only one usable estimate located; no independent corroboration found.
Worth knowing
Leaving Quiksilver to build Outerknown shifted Slater from sponsored athlete toward owner, changing the character of his fortune without revealing its exact value.
