Costco Analysis – Explore The Moat Is The Unique Corporate Culture

Costco (COST) is a US retailer and for good reasons one of the most admired companies in the world. Costco’s management style, with a focus on integrity and treating both the employees and customers right, is the cornerstone of their mission statement. Such a “simple” model has rewarded the shareholders massively. Charlie Munger, who sits on the Board of Costco and Berkshire Hathaway, said the following about Costco in a Forbes interview in 2011:

It’s one of the most admirable capitalistic institutions in the world. And its CEO, Jim Sinegal, is one of the most admirable retailers to ever live on this planet…I just can’t say enough about my admiration for Costco. More of you should look at Costco……It has a frantic desire to serve customers a little better every year. When other companies find ways to save money, they turn it into profit. Sinegal passes it on to customers. It’s almost a religious duty. He’s sacrificing short-term profits for long-term success.

Charlie Munger is undoubtedly an investor worth listening to, and below are some bullet points on what makes Costco pretty unique in the retail world:

Let’s summarize Costco’s unique culture:

  • A simple business model where members pay a membership fee upfront. Items sold have only a tiny profit margin. Thus, the main income is from the membership fee.
  • Costco receives a “float” when the members pay in advance. This is like a perpetual interest-free loan with no strings attached – no covenants.
  • The membership fee is placed as a current liability in the balance sheet when in fact this is a perpetual liability. Thus, working capital is in reality even stronger and provides more funds for organic growth.
  • Not only are the members funding parts of the business, but also to some degree the suppliers as well. This is because Costco turns around the inventory faster than it pays the suppliers.
  • Clearly, Costco offers a lot of value for its customer, otherwise, they would not renew. The retention rate is 90%.
  • Very able management (recruited internally). Charlie Munger is on the board.
  • Skin in the game: All directors and executives own in total 952,000 shares worth about $235 million. The biggest shareholder is Craig Jelinek, CEO, with 311,000, and second Charlie Munger at 184,400. Furthermore, Berkshire Hathaway owns 1% of the company.
  • Some years ago Munger said Costco is the company he admires the most.
  • Costco is recession-proof: The stock had a much lower drawdown than the market in 2008/09: 36% vs. 50%. Why is this important? The less a stock falls, the higher the base of the recovery. Because of the compounding effect, I always prefer stocks that are as less cyclical as possible.
  • In 2009 net sales shrank 1.5%, net income fell 15% and comparable sales fell 4%. But overall, Costco gained market share during the crisis.
  • Able and satisfied employees: Costco has committed to not only low prices but also high wages. Costco pays and treats its employees fairly, and thus has a low turnover and higher productivity. Costco has consistently been among America’s three best employers.
  • The Kirkland Signature: This is Costco’s own brand and only sold at Costco. This accounts for 25% of the sales. The products are manufactured only for Costco, and done for products where Costco assumes it can do it cheaper and better on its own. Customers know the quality is just as good as anything else. The Kirkland label is synonymous with quality and value.
  • Costco has leverage and scale. It can buy in bulk and negotiate low prices. The prices offered by Costco can compete with any online business, like for example Amazon.
  • Growth is solely organic. There is no risk for ill-fated M&A. Growth is opened gradually and in a planned manner.
  • The balance sheet is strong and free from goodwill and intangibles. Long-term debt is only 1x EBITDA.
  • Both the land and the buildings in the US are owned by Costco, thus most likely “hidden” value in the balance sheet.
  • Costco prefers paying a dividend over buying back shares (based on their actions). The dividend was initiated in 2004 and it’s been increased ever since with special dividends now and then.
  • Despite being a huge company, I still believe the runway is long due to its international expansion.

Because of all the positives, Costco always trades at high multiples. The current valuation is a P/E of 37. This is the highest it’s ever been, perhaps rationally so because of the very low interest rates. I believe Costco is mostly “immune” to Amazon because of its membership structure and competent management. Costco’s model is still thriving and has shown resilience.


The main asset in Costco is its culture. The moat, a result of a clear mission statement and management style, is easy to replicate on paper but very hard to practice decade after decade. It’s no easy task to manage its mission statement considering Costco is the world’s second-biggest retailer with over 220 000 employees. To accomplish this, much of the management is decentralized to the local branches with one single vision: Costco is in the market to serve its members. Thus, their competitive advantage is the goodwill from the customers. The biggest risk is that management gets greedy and lacks trust among the members.

I believe a company serving its customers fairly does more for mankind than any charity. Costco is most likely such a company, and this is the main argument for investing in Costco. As long as this culture is intact, Costco will do well.  You need a long-term focus and deep in-grained corporate culture to deserve the trust of the members. Costco has accomplished that. The only negative is the valuation.
