Covered by Stratosphere

Doing One Thing Great

The leading warehouse club, Costco, has membership warehouse operations found worldwide. However, most sales are generated within North America, particularly Canada and the US.

Costco sells memberships that allow customers to shop in its warehouses, which feature low prices on a limited product assortment. Costco sells a wide variety of products and services, including foods and sundries, non-foods (e.g., appliances, electronics, office supplies, domestics, jewellery, etc), fresh foods, and other ancillary products and services (e.g., gasoline, pharmacy, optical, travel, among others).

Costco mainly caters to individual shoppers (80% of paid memberships), but roughly 20% of paid members carry business memberships. Costco's warehouses average around 146,000 square feet and over 75% of its locations offer fuel.

Investment Thesis

  1. Costco has an obsession with giving members the lowest price for products through its supplier relations and negotiating / pricing power. The business is financially optimized despite low retail gross margins, a unique model compared to other retailers.

  2. Costco's membership model creates a network effect and feedback loop. With more members, Costco benefits from greater economies of scale which, in turn, leads to lower prices for members.

  3. Costco' private label brand, Kirkland Signature, exemplifies Costco's commitment to excellence and quality. With Kirkland, Costco is able to replicate or beat the quality of the best-known brand in the category while collecting higher margins.

  4. Costco's selective and capped stock kept units ("SKU[s]") methodology is in place to ensure floor products are placed on shelves with intention and purpose. The business is obsessed with store optimization and increased basket sizes to achieve same store sales growth and industry leading revenue per square foot.

  5. Costco has seen tremendous success expanding into international markets. Its entry into markets like China, South Korea, Japan, Taiwan, and even Iceland have shown the global appetite for Costco’s wholesale model. The business will be able to continue to open new warehouses and take advantage of these global opportunities.

Key Company Metrics

A set of metrics we constantly keep updated to monitor the investment thesis.

Competitive Advantages

The Costco Flywheel

A growing consumer base creates a positive feedback loop for Costco. Each incremental member benefits the existing pool.

Costco has immense negotiating power with its suppliers. Products are sold in bulk at Costco, which means Costco constantly buys large amounts of inventory from its suppliers. Because of the sheer size of these inventory purchases, Costco is able to buy at low prices per unit due to the size and speed of its inventory turnover. Costco is a large customer to its suppliers, so the suppliers work to keep Costco happy by keeping prices low.

This kind of negotiating power is only possible due to Costco's substantial member base. As Costco’s membership base increases, Costco has better economies of scale and negotiating power with its suppliers. This is a classic example of a strong network effect - a wider customer and supplier network introduces more members on both sides due to the advantages both attain from shopping at, or doing business with Costco.

Everybody wins - Costco members get great prices, suppliers are able to move huge amounts of products and services through the Costco network, and Costco fulfills its goal of being customer-centric.

Costco's Business Model/Positive Feedback Loop

This flyhweel effect exists because Costco truly understands the importance of a customer's shopping experience. Costco has established a customer-centric culture that focuses on customer satisfaction and is known for its lenient return policy through which members can return almost any product, no questions asked.

Since its foundation, the company has strived to create a culture that cares for the customer and staff satisfaction. The result is brand loyalty, an efficient workforce, and a differentiated brand. Perhaps, then, it is no surprise that Costco holds a near 90% renewal rate with its members.

Store Layout Optimization

Costco's value proposition inherent in its operations (membership-only, bulk purchase / low unit cost shopping for customers) make it an efficient business generating tons of money.

The company's revenue per square foot continues to rise and sits over $1,600 / square foot as of 2021. Other retail behemoths, like Home Depot, Walmart, or Lowe's, have sales per square foot readings that are fractions of Costco's figures.

Costco's warehouses (i.e., store locations) contain skids of products for members to purchase products from, mimicking exactly what a wholesale warehouse looks like. This warehouse model has product handling advantages as customers can select products directly from the warehouse floor. The stores do not look pretty because they do not have to - customers are there for the low prices and bulk purchases that their memberships entitle them to. While other retailers stock shelves with an attempt to make them look appealing, Costco saves this effort and pockets the savings.

This method of storing inventory introduces supply chain advantages through limiting the number of touchpoints and hand-offs of skids and groups of items. The more checkpoints there are between the original manufacturer to the location customers purchase the products from, the more expensive, inefficient, and room for error the supply chain process gets. Costco circumvents several checkpoints that other retailers deal with by unloading products in a warehouse in their original full packaging on a pallet.

Costco also caps the number of SKUs (i.e., unique item categories) it carries at 4,000. While stores like Walmart can carry as much as 40,000 SKUs, Costco maintains this cap to focus on products with quality, low price, and a reputable brand. These products are also only found in one packaging format per item to maintain simplicity.

This comprehensive model makes it easier for Costco to strategically place all of its products in the warehouses to optimize space. It also gives Costco an easy method to update or refresh the warehouse layout every month. These strategies are tailored in a way to ensure that each store can generate the most sales per square foot by encouraging customers to walk around the store and pass by varied items. If products are placed in accordance with this strategy, Costco will benefit from customers purchasing larger basket sizes, on average.

A strategy is only as good as the degree of positive impact it has on key financial metrics. Costco's inventory turnover ratio (i.e., a measure that estimates the number of times the company turns over all of its inventory in a year) has been hovering around 12x over the last decade. Once again, this is much higher than other large retailers, like Walmart or Home Depot.

The company is efficient with its store model, and as a result, it is able to sell tons of inventory to members. The more "turns" Costco can get with its inventory, the more revenue, and ultimately profit, the company is able to generate.

The Kirkland Signature Brand

Costco sells some products through its in-house, private label brand, Kirkland Signature. This brand exists primarily because Costco is able to control the cost and, therefore, the consumer price of this product line. Kirkland covers a vast range of items, from food and home items to supplies and self-care products.

Costco specifically targets product categories that contain high-priced products. Through Kirkland, it can then undercut those relatively expensive items by creating a viable and relatively cheaper alternative. Customers have these alternate options at Costco, and nowhere else - at least not to this extent.

Additionally, Kirkland Signature holds substantial brand power as consumers are familiar with Costco and its values, which are reflected in the brand's products through good quality at a low price.

With this brand power, Costco is able to draw customers to continue being members and shopping at its stores due to the exclusivity of Kirkland products.

Opportunities Ahead

  • Better late than never. Costco is working on perking up its e-commerce offerings despite being rather late to the concept. Costco offers 2-day delivery on non-perishables and household supplies and same-day grocery delivery in "most metropolitan areas" in the US. E-commerce capabilities also exist in 7 other major markets, including Canada. Costco has embraced the omni-channel approach, which we believe will highly complement the outstanding in-person shopping experience at Costco for members. We also think members' in-store shopping habits will not change much with Costco's e-commerce efforts - that is, basket sizes will remain large and could potentially continue to increase. After all, many customers shop at Costco for price > convenience.

  • An opportunity in keeping things the same. There is an opportunity for Costco to quite literally keep doing what it is doing - open stores in prime locations, focus on product and quality, and help drive shopper savings. As long as Costco keeps up its value proposition, we see it being able to maintain renewal rates around 90% or even higher. If it does this, Costco can focus on increasing basket sizes by introducing new and / or relevant third-party products and services, as well as new Kirkland product lines that serve as viable alternatives to their more expensive third-party counterparts

  • A membership fee increase could drive margin and profit growth. The last time Costco raised membership fees was in 2017. It has been about five years since the last fee hike, so there could be another hike on the horizon. If Costco chooses to modestly raise its fees, we think members will continue to renew at high rates. This should highly benefit Costco financially with those increases falling straight down to the bottom line profits.

Risks

Competition

In the US, there are a handful of competitors who stand against Costco, such as Walmart's Sam’s Club and BJ's Wholesale Club. Both competitors hold a similar focus to Costco, providing memberships to gain access to wholesale items.

Sam's Club's main advantage over Costco is its membership fees being 25% cheaper. This difference in price may the defining factor for many customers as both businesses have similar structures.

Costco's operations are mainly found in the US and Canada, which make up over 85% of revenues and over 80% of operating profit combined.

The US and Canada are regions in which e-commerce penetration is really high, with many alternate options as well. While the value proposition at Costco remains strong today, e-commerce options like Amazon and Walmart that offer thousands of items with free shipping and in some cases, same-day delivery, pose a threat to Costco for purchases like electronics and other ancillary, primarily non-food items.

Physical-First Model

Costco's business model and success to date is attributable primarily to its warehouse shopping via paid membership approach, success despite a limited inventory selection, and immense bargaining power it has been able to achieve.

However, e-commerce is growing, millennials are taking an increasingly larger share of the market, and consumers of today prefer online shopping to a much larger extent than the consumers of 20 or 30 years ago.

Costco, therefore, faces a dilemma here. On one hand, e-commerce through an omni-channel approach for large brick-and-mortar retailers is absolutely necessary. On the other hand, doing so could wipe out many of the cost efficiencies that got Costco to the state it is at today.

Costco, however, continues to believe that members will continue shopping at the store. In the Q3 2020 earnings call, CFO Richard Galanti stated, "We still want you to come in. You're going to buy more stuff when you come in, period ".

Unlike any other brand, Costco is able to offer incredibly low prices. In fact, without membership fees, Costco would make virtually no money (assuming everything about its operations remained the same). The membership fees are the largest driver of profits and is what enables Costco to provide such low-cost products and services.

With that, we believe that consumers will continue shopping at the store to take advantage of these low prices. Anecdotally, anyone can attest to the long lines at Costco pumps or within the store. Traffic is high and the spend per member continues to rise.

Overall, e-commerce should act as an opportunity to Costco, as long as most members continue shopping in store. Without the in-store benefits, the value proposition of Costco could quickly fade away.

International Expansion

As Costco continually looks to expand its business into other countries, the risks arise if these stores do not have the same uptake as North American locations. People around the world support different values and the same success strategy in one part of the world may not always translate to another part.

If Costco does have a location that is not successful in a certain country, it may affect Costco’s plans for international expansion.

However, as of right now, we see no significant risk in these expansions as Costco has a proven track record of success in countries such as China, Iceland, Japan, and South Korea.

International expansion is certainly part of the growth opportunity for the business.

Valuation

Costco shares have appreciated substantially in recent years, mainly due severe multiple expansion.

While the underlying business fundamentals have grown at impressive levels - attesting to the high quality of the business - the company trades at an earnings multiple above 40x, more than double that of its peer average (Walmart, Target, BJ's Wholesale Club, etc).

Given the competitive, e-commerce, and international expansion risks, we think the valuation today is rather unattractive. Even if Costco doubles its EPS over the next 5 years, the company would still be trading at a low 20s P/E ratio at today's share price. This is roughly the average that Costco's peers are trading on next year's earnings.
