Compensation spread. Offered wages on Core-Mark US LLC’s H-1B petitions range from $68,539 at the low end to $189,813 at the high end, with a petition-weighted average of $128,768.

H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.
