Secrets to success
Despite no reliance on franchises, Chipotle's growth curve has been phenomenal. Steve Ells, founder of Chipotle, opened the first Chipotle restaurant in 1993 hailing it as a fast casual outlet that gives an upscale dining atmosphere with quality food for higher prices. What sets Chipotle apart from other restaurant chains is its solid restaurant level operating margin that has consistently stayed north of 20% in the last five years.

Chipotle's performance is supported by its dedication toward "Food with Integrity." The use of naturally raised ingredients, dairy products, and its customizable menu have made it an extremely popular eatery. Restaurant goers love the fresh fare so much that they are willing to pay a premium, giving Chipotle pricing power in an industry dominated by value menus. Even a 6.5% hike in average prices per menu in the second quarter of 2014 did not dent its popularity. On the contrary, its foot traffic continued to increase. Second quarter same store sales growth was a remarkable 17.3%. And the best part is that only 2.5 percentage points came from the price increase, while the remainder came out of increased transactions.

The company also owes a lot of its success to its assembly line business model which allows it to serve as many as 65,000 possible freshly made combinations to customers at record speed. Together with the enhanced customer experience, this allows Chipotle to serve more customers, and in turn increase its sales and profits. According to an industry publication, some of Chipotle's stores handle more than 350 transactions per hour during lunchtime, while the national average, as per the company's co-CEO Monty Moran, is between 110 and 120.

Investment strategies to cement growth
The robust operating margin allows Chipotle to generate high returns on its assets and its overall investments. And the company creates long-term value for its shareholders by making continued investments in store unit growth -- but management's been extremely particular about selecting the restaurant location.

Identifying the right location is a must for success, and Chipotle is fully cognizant of this fact. More often than not, restaurants set up in high streets or areas of special interest are seen to perform very well. Chipotle refers to these places as "proven markets", and has said that it will open 70% of its new restaurants here, while the remaining shall be equally split between "developing or established markets" and "new markets." In the second quarter of 2014, Chipotle's new restaurant opening sales volume stood between $1.6 million and $1.7 million, which the company expects to increase to $1.7 million and $1.8 million. 

Chipotle manages its expansion program very tightly. While other restaurateurs heavily depend on franchising for expansion, the company does not go for franchising at all -- first, because it's easier to retain control on offerings and maintain the "food culture" in owned restaurants. Second, with more than a billion dollars in cash, the company is self-sufficient to fund its expansion instead of raising money through franchising fees. 

Capital expenditures and new stores
In the last five years, Chipotle has grown its store count by 13%-15% every year, thereby adding more than 600 new stores. More than 98% of its outlets are located in the U.S., with a few in Canada, England, France, and Germany. The restaurant chain targets to open 180 to 195 new stores in fiscal year 2014 ending December 31, including a few ShopHouse and Pizzeria Locale restaurants. In the first six months, it has opened 89 new restaurants, raising the total store count to 1,681.
