Jun. 20, 2014 is bound to be a pretty big day for investors holding shares in Darden Restaurants (NYSE:DRI). Prior to the market opening, the restaurant conglomerate's management team will be releasing revenue and earnings results for the fourth quarter of the company's 2014 fiscal year. With this in mind, the Foolish investor is probably trying to figure out what to do. Should he/she sell the company's shares and buy into a rival like DineEquity (NYSE:DIN) or Brinker International (NYSE:EAT) or does Darden have what it takes to soar higher, even in spite of its pending sale of Red Lobster?

Mr. Market's expectations are mixed
If analysts are correct, Darden will report revenue of $2.33 billion for the quarter. If this forecast comes to fruition, it will represent a 1% improvement over the $2.30 billion management reported the same quarter last year. More likely than not, this would be due to its core restaurants like Olive Garden and Red Lobster seeing sales decrease while smaller chains like Bahama Breeze and Eddie V's continue their growth spurt.

From an earnings perspective, analysts are even more pessimistic about Darden. For the quarter, Mr. Market expects the restaurant chain to post earnings per share of $0.94, 7% below the $1.01 the business reported during the fourth quarter of its 2013 fiscal year. Despite seeing slightly higher revenue, the company will likely see its margins fall because of its bigger chains, which tend to have higher margins themselves, posting smaller revenue and, potentially, impairments.

Is Darden a better treat than the rest?
Over the past four years, Darden has seen some decent revenue growth. Between 2010 and 2013, the company saw its revenue climb 20% from $7.1 billion to $8.6 billion. According to the company's financial statements, this top line improvement came from slight increases in its Olive Garden and Red Lobster chains, but was mostly attributable to a 39% jump in its LongHorn Steakhouse operations and a 165% rise in its Specialty Restaurant Group.

While Darden's revenue growth was pretty good over this four-year period, its bottom line wasn't anything to brag about. Between 2010 and 2013, the company saw its net income rise by just 2% from $404.5 million to $411.9 million. Despite its higher revenue, Darden was negatively affected by its cost of goods sold, which inched up from 77.1% of sales to 77.9%.

Over a similar four-year period, rival DineEquity saw its revenue fall a jaw-dropping 52% from $1.3 billion to $640.5 million. Although this seems disastrous at first glance, the parent of Applebee's and IHOP has been transitioning to a business model whereby 99% of its locations have been refranchised as opposed to remaining company-owned. The downside to this approach is that it results in less revenue but, since the company takes some off the top of its franchisees, it leads to higher margins.

This is exactly what DineEquity has seen during this timeframe. Between 2010 and 2013, the restaurant chain saw its net income jump from a loss of $2.8 million to a gain of $72 million. Despite being hit by lower sales, the company's margins improved drastically, especially its cost of goods sold, which fell from 67.8% of sales to 42.3%.

Another interesting player in the food business in recent years has been Brinker International. Over the past four years, the parent of Chili's saw its revenue dip down just 0.4% from $2.86 billion to $2.85 billion. This slight dip in sales came in response to a 5% rise in the number of franchised locations the business recorded, but was offset by comparable store sales declines in 2011, followed by stronger performance in 2012 and 2013 that sent sales higher.

In light of the restaurant's decision to increase its ratio of franchised to company-operated locations, management has been able to increase its bottom line by 19% from $137.7 million to $163.4 million. By adopting this practice, Brinker International saw its cost of goods sold fall from 84.1% of sales to 81%.

Foolish takeaway
Heading into earnings, investors are right to worry about Darden. Yes, the company has had a nice run-up in revenue compared to its peers, but with its two largest (soon to be one after the company finishes its sale of Red Lobster) restaurants seeing sales drop and with margins contracting, an investment in the firm is not without risk. While it is possible that Darden could prove to be an attractive long-term investment, for the Foolish investor interested in rising profits, DineEquity and Brinker International make for good prospects to analyze further.
