Fun facts about Costco Wholesale Corp

Quirks, history, and lore behind COST — the kind of stuff that makes a stock memorable.

  • 1
    The Basics
    U.S. consumer company · mega-cap · listed on Nasdaq · headquartered in Washington State.
  • 2
    The Numbers
    Revenue around $280 billion a year — more than Microsoft — yet its net profit margin is under 3%. Volume is the whole business model.
  • 3
    The History
    Founded in 1983 in Seattle, it merged with its biggest rival a decade later and perfected a retail format that barely existed before it: pay to get in the door.
  • 4
    The Secret
    Selling things is almost a side hustle — the majority of its profit comes from annual membership fees, not the products on the floor.
  • 5
    The Lore
    Its in-house Kirkland Signature brand alone does more revenue than Nike. Charlie Munger sat on its board for 26 years and said he'd never sell a share.
  • 6
    The Giveaway
    140 million membership cards. A rotisserie chicken at $4.99. And a $1.50 hot-dog combo whose price hasn't moved since 1985.
