THE 9 MOST SUCCESSFUL RETAIL STORES IN THE USA

Apple (AAPL) has the most successful retail stores by a wide margin.

According to RetailSails, a retail and consumer goods consulting firm, the tech giant's 372 worldwide locations sold goods at a rate of more than $6,000 per square foot of floor space in the past 12 months. The average store of the next most successful company in the United States, Tiffany & Co. (TIF), sold less than half that per square foot.

In low-end department stores and supermarkets, sales per square foot were in many cases less than $100. Hancock Fabrics, a fabric retailer, brought in just $72 per square foot. Meanwhile, retailers with the most profitable stores brought in more than $1,000 per square foot. These are mostly high-end brands, selling much more expensive products. Based on the RetailSails report, 24/7 Wall St. identified the nine most successful retail stores in America.

In the case of most department stores and discount stores like Wal-Mart Stores (WMT), Kmart and Family Dollar Stores (FDO), most items cost less than $100, and most stores are very large. The average retail space in some of the least successful stores by sales per square foot is at least 10,000 square feet. This prevents total profits per square foot from exceeding several hundred dollars, even among the most popular stores.

For the nine most profitable corporate stores, the opposite is true. They sell luxury goods, in apparel, accessories, electronics or jewelry. Their products are often quite expensive, while the stores are generally relatively small. Much of the merchandise companies such as Apple, Tiffany and Coach (COH) sell costs in the hundreds of dollars or more. At the same time, the average store floor space is less than 5,000 square feet. While total sales of the average Kmart store is roughly double what Lululemon Athletica (LULU) stores do, the average floor space of a Lululemon is only 1/34th that of a Kmart store.

Because most of the most profitable stores sell luxury items, they tend to be more selective in the markets they enter. Several of these companies have fewer than 100 stores nationwide. Birks & Mayors (BMJ) has only 57. Even stores that average small retail space, such as RadioShack (RSH), turn low profit per square foot because they have hundreds of low-profit stores in low-income communities. RadioShack has 4,423 stores.

In many ways, Apple, the most successful store in terms of profit per square feet, is different from each of the other eight companies on this list. Companies like Tiffany, Coach and Select Comfort (SCSS) rely primarily on their brick-and-mortar stores. Apple makes the vast majority of its sales and profits online, with its physical stores serving as hubs to improve branding and showcase new products.

Apple's business model of regularly releasing new buzz products, such as the latest iPhone, draws large crowds of customers looking to buy these items as soon as they hit the shelves.

Relying on RetailSails' 2012 Chain Store Productivity Guide, 24/7 Wall St. identified the nine companies with the highest sales per square foot, based on the past 12 months of sales. RetailSails also provided average store size, average annual sales per store, one-year sales growth and the number of stores.

These are America's most profitable stores:

9. Birks & Mayors> Sales per sq. ft.: $1,082
> Sales per store: $4.61 million
> No. of stores: 57
> 1-yr. sales growth: 5.2%
> Revenue: $302.3 million

Birks & Mayors is a designer, manufacturer and retailer of jewelry, timepieces, silverware and gifts in the United States and Canada. It operates 32 stores under the Birks brand in Canada, 24 stores under the Mayors brand across Florida and Georgia, among a few others. Although it has fewer stores than any of the nine most successful stores, it still manages to have sales of $4.6 million per store. However, its revenue growth in the past year has been only about 5%, and shares are trading near a 52-week low.

8. Vera Bradley> Sales per sq. ft.: $1,186
> Sales per store: $2.39 million
> No. of stores: 70
> 1-yr. sales growth: 79.2%
> Revenue: $460.8 million

In the first half of fiscal 2013, Vera Bradley Inc. (NASDAQ: VRA) opened 12 full-price stores and two outlet stores. This maker and retailer of "stylish and functional" accessories for women says it plans to open between 14 and 20 stores in each of the next five fiscal years, greatly adding to the 70 stores it had as of the end of July. Vera Bradley had the highest one-year sales growth, at 79.2%, in the RetailSails report. Net income last year was $57.9 million. The company's share price is down more than 15% since beginning of this calendar year.

7. True Religion

> Sales per sq. ft.: $1,227
> Sales per store: $2.35 million
> No. of stores: 116
> 1-yr. sales growth: 21.0%
> Revenue/net income: $419.8 million

Since its founding in 2002, True Religion Apparel (NASDAQ: TRLG) has grown into a $640 million global company with distribution in 50 countries. In addition to its 116 U.S. stores as of the end of July, the company also sells its denim jeans and other casual and sportswear and accessories through other major retailers and department stores such as Neiman Marcus and Nordstrom (NYSE: JWN). Last year's revenue of $419 million was less than most other retailers on this list. For investors, it has been something of a roller coaster ride, with the share price up more than 58% in 2011, but down about 25% so far this year.

6. Select Comfort> Sales per sq. ft.: $1,314
> Sales per store: $2.00 million
> No. of stores: 381
> 1-yr. sales growth: 32.6%
> Revenue: $743.2 million

Select Comfort had, as of June 30, 381 company-operated Sleep Number stores across the United States, selling adjustable-firmness beds and other sleep-related accessory products. That is after both opening 22 stores and closing 22 stores in the first half of 2012. But the company said it expects a net increase in store count to between 400 and 410 by the end of the fiscal year. The company's revenue jumped 32.6%, the 10th highest in the report. The share price more than doubled in 2011, and year-to-date, the stock price rose another 18%.

5. Michael Kors> Sales per sq. ft.: $1,431
> Sales per store: $3.24 million
> No. of stores: 253
> 1-yr. sales growth: 77.9%
>Revenue: not available

Luxury lifestyle products retailer Michael Kors Holdings (NYSE: KORS) saw the second largest revenue growth, at 77.9%, among the more than 200 companies reviewed by RetailSails. The company's share price rose more than 110% since the initial public offering in mid-December last year. The company believes there is long-term potential to grow its store base to 400 in North America and 100 each in Europe and Japan. The company said in its just-released second-quarter fiscal 2013 report that, including licensed locations, there were 349 Michael Kors stores worldwide at the end of September.

4. Coach> Sales per sq. ft.: $1,871
> Sales per store: $5.19 million
> No. of stores: 833
> 1-yr. sales growth: 15.9%
>Revenue: $4.8 billion

Best known for its high-end leather handbags, Coach had 833 stores worldwide as of the end of July, more than any of the nine most successful retailers on this list. Its $4.76 billion revenue last year was higher than all the other retailers on the list except for Tiffany and Apple. Coach's primary markets are the United States and Japan, which account for about 80% of all stores. It had a respectable 15.9% one-year sales growth last year, but so far in 2012, Coach's share price has declined more than 11%.

3. Lululemon Athletica> Sales per sq. ft.: $1,936
> Sales per store: $5.49 million
> No. of stores: 189
> 1-yr. sales growth: 38.6%
>Revenue: $1.0 billion

Founded in 1998, Lululemon is a yoga and sporting apparel company headquartered in Vancouver, British Columbia. Not only are its sales per square foot higher than all other retailers on this list except two, but its sales per store are higher than most apparel stores as well, even though it has substantially less store space than other companies. Still, Lululemon's one-year sales growth was the eighth highest on the RetailSails list, and its share price is up nearly 50% year-to-date. The company said it expects to open 30 stores in the United States by the end of the fiscal year.

2. Tiffany & Co.> Sales per sq. ft.: $3,017
> Sales per store: $13.02 million
> No. of stores: 260
> 1-yr. sales growth: 9.6%
> Revenue: $3.6 billion

Diamonds are small and pricey, so it should come as no surprise that this luxury jeweler can be found near the top a list featuring sales per square feet. In fact, Tiffany's sales per square foot are about 35% higher than that of Lululemon, the next highest on the list. Tiffany opened its first store in 1837. As of the end of July it had 260 stores. In the second half of the year, the company said it expects to open nine stores in North and South America, five stores in the Asia-Pacific region and one store in Europe. The share price is down about 7% year-to-date.

1. Apple> Sales per sq. ft.: $6,050
> Sales per store: $51.14 million
> No. of stores: 372
> 1-yr. sales growth: 28.9%
> Revenue: $156.5 billion

Apple is a relative newcomer on the retail scene, with its first store opening in 2001. Yet, Apple's $6,050 per square foot is more than double that of Tiffany's, the next highest on the list. Apple also has the ninth highest sales per store among companies measured by RetailSails, at more than $51 million, and the 13th highest one-year sales growth, at 28.9%. Apple benefits from constant new product introductions and upgrades of existing ones, as well the fact that so much of its revenue comes from non-store sales. This business model has made Apple the world's largest public company, with a market capitalization of more than $510 billion, which is more than Microsoft (NASDAQ: MSFT) and Google (NASDAQ: GOOG) combined. In the first nine months of fiscal 2012, Apple opened 15 stores, including four in the United States, four in Spain and two in France.
