Shares of Chipotle Mexican Grill, Inc. (NYSE:CMG) surged to a new 52-week high above $400 on Friday following a strong Q2 earnings report. Chipotle stock peaked around $440 last year, before losing nearly half of its value because of concerns that growth was petering out.
One big blow on the way down was the short thesis outlined by David Einhorn at the 2012 Value Investing Congress. Einhorn argued that Yum! Brands, Inc. (NYSE:YUM) would steal market share from Chipotle Mexican Grill, Inc. (NYSE:CMG) with its new Cantina Bell concept that offers higher-quality food than the typical Taco Bell menu but undercuts Chipotle on price.
Einhorn’s argument has not found much support in Chipotle’s recent performance. Chipotle Mexican Grill, Inc. (NYSE:CMG) restaurants are as busy as ever, and the company is still growing strongly. That said, I believe most of the profit has already been made for Chipotle investors. Chipotle stock now trades for more than 30 times forward earnings, and further multiple expansion is unlikely unless Chipotle shows investors that it can significantly increase its profit margin.
A reassuring quarter
In Q2, Chipotle Mexican Grill, Inc. (NYSE:CMG) posted an 18.2% increase in revenue because of new restaurant openings as well as a 5.5% increase in comparable restaurant sales. The comp growth was particularly reassuring for investors, because comparable restaurant sales grew by just 1% in the prior quarter.
A large part of the difference was a calendar shift that resulted in two fewer days in the first quarter and an extra day in the second quarter. That said, according to CFO Jack Hartung, the underlying trend still improved by 150 basis points from Q1 to Q2 after adjusting for the calendar shifts.This performance led Chipotle Mexican Grill, Inc. (NYSE:CMG)’s management team to increase the company’s 2013 sales guidance. As a result, investors drove Chipotle stock up by more than 8% on Friday.
Can margins keep growing?
Chipotle Mexican Grill, Inc. (NYSE:CMG) has grown revenue and earnings at an impressive rate since the Great Recession. Earnings growth has been boosted by significant margin expansion over the past five years. Chipotle’s strong comp sales growth allowed it to better leverage its fixed costs. This margin expansion can be seen from the fact that earnings growth has significantly outpaced revenue growth for the past five years.
However, for the first half of 2013, Chipotle Mexican Grill, Inc. (NYSE:CMG)’s pre-tax margin dropped from 17.8% to 17.3%. This was the result of more modest comp growth, which created less operating leverage, and rising food costs that weren’t offset through menu price increases.
Chipotle Mexican Grill, Inc. (NYSE:CMG) announced on last Thursday’s earnings call that it doesn’t intend to raise prices at all this year. The company is in the midst of a campaign to remove genetically modified organisms from its food. That’s driving some of the cost increases, since it’s difficult to find suppliers of non-GMO ingredients. However, management wants to wait until Chipotle is 100% GMO-free before raising prices.
