Walmart & Costco - Customers & Trends

Some of us won't spend $30/year at Walmart, and have given up on BJ’s.  We'll shop Costco, though. But as a
shareholder (like Berkshire) I like Walmart.  Costco and Walmart have completely different customers. And Costco’s demographic group is much smaller.

Most of America can and does shop at Walmart. Much of the world can afford to, and can benefit from the privilege. While Costco’s unit pricing on items might be better, its bulk purchase requirements and higher-dollar offerings put it out of the reach of much of America and most of the world. Walmart’s core customer is paycheck-to-paycheck. Costco’s proposition doesn’t work for that demographic.

On the subject of leverage, financing, and float, Walmart and Costco both excel in another area: supplier financing. Combined with good inventory management and the resulting high turnover, aggressive supplier terms are a form of free float. Costco has historically had more than 100% of its investment in inventory paid for by suppliers (ie, they completely sold out and even received the re-order before the bill for the first shipment was due). They are ‘down’ to having their inventory 97% supplier financed now. This is still pretty remarkable, considering they do a considerable private label business.

Similarly, Walmart has 92% of its inventory level vendor-financed. Two years ago, when Walmart was at the peak of its private-label foray, Walmart’s inventory was down to 84% financed by suppliers. But Walmart recently has gone back to emphasizing national brands. Customers weren’t recognizing good value in private label, even though it might be inherently there – but they were able to see the value in Walmart’s low pricing of national brands. So brands are back.

That’s good for brands such as Fruit of the Loom and Russell, but in return for throwing business their way, Walmart obtains excellent payment terms. Buffett, particularly, must have an appreciation for the idea that Walmart can extract free financing from him, and that he’ll gladly(?) provide it. (Including McLanes and Berkshire’s brands, Walmart is easily Berkshire’s largest customer in dollar terms, representing maybe 7% of Berkshire’s top line revenue – though of course a miniscule share of its earnings).

One of the more persistent things we keep hearing in the news is is ‘same store sales.’ Innumerable analysts and financial reporters have written about the importance of this particular metric. And understandably. But this is one of those mostly-for-public-consumption things. Internally, retailers – at least the good ones -are fully focused on profitability, and there is far, far more emphasis of the profitability of each incremental sales dollar than on a ‘same store’ sales performance number. Almost any retailer can get sales growth. Profitable sales growth is another matter altogether.

Another thing to remember is that there’s no industry standard for ‘same store sales.’ Most retailers these days now include their internet business in ‘same store’ reporting, as well as the impact of store remodeling or expansions, or even where they’ve closed a store in a city and opened another in another part of town. This is misleading, of course, and if they were giving credence to these comparisons internally you’d question their common sense. Walmart, to its credit, generally doesn’t play those reporting games (it also doesn’t include any of its more rapidly growing foreign store performance in its ‘same store’ reporting). Not to say that domestic sales trends shouldn't be a concern, but that's only one element of the larger picture. The financial press and markets are incredibly obsessed with that metric, however, and will likely be for awhile.

These days, it can be instructive to look at sales and earnings this past year compared to pre-recession (2007) levels. Otherwise, it’s too easy to get lost on the period-to-period noise. On this basis, Walmart had an overall 12% revenue increase from 2007 to 2010 – and a 19% increase in earnings. Costco had a 20% growth in sales and 20% increase in earnings, 2010 vs 2007.
