Nike: $100 invested at its 1980 IPO would be worth many times more today.

Nike went public on Dec. 2, 1980, after a period of very rapid sales and profit growth. The company later expanded globally and used high-profile athlete endorsements, which helped its long-term market value rise.

Nike is marking 45 years since its initial public offering in December 1980. At the time the company had already grown quickly from annual sales under $2 million in 1972. Reports indicate sales rose at an average annual rate near 85% in the nine years before the IPO, and net income increased even faster. Investors and commentators revisit the IPO to illustrate how long-term holdings in some companies can change over decades. What we know so far: - Nike's IPO took place on Dec. 2, 1980. - Sales were under $2 million in 1972 and reportedly grew at about an 85% average annual rate in the nine years that followed. - Net income reportedly grew at nearly 100% per year in that early period. - By 1990 Nike had become the world's largest sports footwear and apparel company, with reported revenues around $2.23 billion and reported profit growth near 45% for the fiscal year. - The company invested in high-profile athlete endorsements, including reported agreements with Tiger Woods, Serena Williams, and Roger Federer; one high-profile deal has been reported as about $500 million. Summary: An early $100 investment at Nike's IPO would reflect decades of company growth as it expanded its business and brand through global distribution and sponsorships. Exact present-day values depend on calculation methods that account for stock splits, dividends, and the timing of holdings. Undetermined at this time.
