Costco’s Timeless Edge: How Jim Sinegal’s 89-Year-Old Focus Fuels Long-Term Value
3min read At 89 years old, Jim Sinegal, Costco’s co-founder and retired CEO, still walks into the company’s Kirkland, Washington, headquarters weekly. The man who built one of the world’s most profitable retailers—where membership fees alone generate over $15 billion annually—does so not out of obligation, but because he “loves it.” This unwavering focus on his craft, rooted in a philosophy that prioritizes employees and customers over shareholders, has become the cornerstone of Costco’s enduring success. For investors, this mindset isn’t just a cultural relic—it’s a blueprint for sustainable growth in an era of retail turbulence.
The Sinegal Legacy: Culture as Competitive Advantage
Sinegal’s leadership, spanning 28 years as CEO until 2012, was defined by a simple but radical idea: “You can’t say people are your most important product and then treat them like s—.” This ethos shaped Costco’s DNA. The company offers its employees some of the highest wages and most comprehensive benefits in retail, including health care, retirement plans, and paid parental leave. The result? Employee turnover at just 12%, compared to an industry average of 40% in 2023.

This focus on retention and satisfaction has translated into customer loyalty. Members pay $70 annually for access to Costco’s warehouse clubs, but the real value lies in the trust they place in the brand. Sinegal’s “green ink process”—a rigorous quality-control system where executives personally approve every Kirkland Signature product—ensures consistency, driving repeat visits and membership renewals.
The Numbers: A Decade-Long Run
Costco’s stock (ticker: COST) has been a standout performer, rising over 1,900% since its 1992 IPO, outpacing the S&P 500’s 600% gain over the same period. Even after adjusting for splits, the stock has returned 19,000% since 1985, a testament to Sinegal’s long-term vision.
The company’s financials reflect this resilience. In 2023, costco reported net sales of $244 billion, with membership revenue up 9% year-over-year. A dividend yield of 1.2% may seem modest, but the stock’s steady appreciation—up 25% in the past five years—has made it a favorite among income-focused investors.
The New Generation: Vachris and the “Grow From Within” Model
While Sinegal no longer holds an official role, his influence persists through Costco’s leadership pipeline. Current CEO Ron Vachris, a former forklift driver who rose through the ranks, embodies the “grow from within” ethos. At the February 2025 Albers Executive Speaker Series, Vachris reiterated Sinegal’s core principles: “Culture isn’t a program. It’s a way of life.”
Ask Aime: What is the Costco co-founder's legacy on employee retention?
This continuity is critical. Under Vachris, Costco has expanded its private-label offerings and digital capabilities, but its focus on employees remains unchanged. In 2024, the company raised starting wages to $17 an hour, a move that aligns with Sinegal’s belief that “retail is a people business.”
Beyond Retail: The Sinegal Philosophy Spreads
Sinegal’s ideas are now influencing industries beyond retail. Senior living operators, for example, are adopting Costco’s model of high wages and profit-sharing to combat employee turnover. A 2025 study by the National Investment Center for Seniors Housing & Care found that companies implementing Costco-like policies saw retention rates jump by 15–20%.

Meanwhile, Costco’s stock continues to inspire. Its enterprise value-to-EBITDA ratio of 22.5x is elevated, but justified by consistent revenue growth and a moat-like membership model. Competitors like Walmart and Target struggle to replicate Costco’s combination of affordability, quality, and employee satisfaction—a gap Sinegal’s legacy ensures remains wide.
Risks and Considerations
No investment is without risks. Costco’s reliance on discretionary spending makes it vulnerable to economic downturns, and its expansion into new markets faces logistical hurdles. However, its 95% membership renewal rate and Sinegal’s proven playbook suggest it can weather cyclical headwinds.
Conclusion: The Sinegal Effect Endures
Jim Sinegal’s weekly office visits at 89 are more than a personal quirk—they symbolize a corporate culture that values human capital above all else. For investors, this means a company with a 40-year track record of turning employees into advocates and customers into lifelong members.
With a market cap of $280 billion, Costco isn’t a small-cap growth story. But its steady compound annual growth rate of 12% over the past decade, paired with a dividend that has grown at 5% annually since 2010, makes it a rare blend of stability and opportunity.
As Sinegal once said, “You have to take the shit with the sugar.” For investors willing to embrace that philosophy, the sugar—decades of outperformance—still tastes sweet.
In a world of fleeting retail trends, Costco’s focus on what Sinegal calls “the basics”—fair pay, trust, and quality—remains its secret to enduring value. Buy, hold, and let the focus do the rest.
