NEW YORK (TheStreet) -- Shares of Kraft Foods Group (KRFT) are paring some of the gains from yesterday, down 1.26% to $82.12 in pre-market trading today, as Goldman Sachs removes the company from its "Americas Conviction Buy List," while raising its price target to $93 from $73 after a merger announcement with H.J. Heinz Co. yesterday.

"We remain 'buy-rated' but remove KRFT from Americas Conviction List on outperformance and diminished near term upside; since adding KRFT to the Conviction List on January 15, the stock is up 26.6% versus the S&P 500 more than 3.4%," analysts said.

"We see value creation potential for the new entity and raise our price target on higher fundamental value [70%] multiples [P/E & EV/EBITDA of 27X/16X, from 19X/12X] and existing M&A value [30%] of $82 on 12X EV/EBITDA," analysts added.

Regarding the Heinz contribution to Kraft, Goldman Sachs assumes sales growth of negative 5% in 2015 for HNZ, based on 3.5% constant-currency sales growth and FX impact of negative 8.5% based on HNZ's country exposure.

For 2016 and 2017, they assume sales growth of 3.5%, in-line with historical average. They assume a range of synergies around management's guidance of $1.5 billion and also assume HNZ's 2014 margin of 20.3% achieves slight expansion on new operator.

Yesterday, Kraft agreed to merge with Heinz in a deal structured by Berkshire Hathaway (BRK.B) - Get Report and 3G Capital that will create the third largest food and beverage company in North America and the fifth largest in the world.

Insight from TheStreet's Research Team:

The Street's Jim Cramer, Portfolio Manager of the Action Alerts PLUS Charitable Trust Portfolio, wrote this in Realmoney.com after the merger announcement:

Like everyone else who didn't own Kraft (KRFT) last night, I kicked myself for missing it. Let's see; three-and-a-half percent yield, down for the year, household brands, lower input costs across the board in the second half of the year.

How could you not like that? Especially considering that they make Cheese Whiz, the favored ingredient of cheese steaks everywhere, which I am told, by the way, actually has a real smidgen of cheese in it?

Yet, therein lays the rub. The fact that I could make a joke about whether Cheese Whiz has any real cheese in it is why I haven't liked this stock for anything but a takeover play in the years since it was created. The fact that before I wrote this I Googled to see if Cheese Whiz actually had any real cheese in it and found an actual and I am sure well-worn entry posing that exact question -- the answer is it has some but not as much as it used to -- tell you more about why I didn't own it than anything else.

Kraft, you see, is the antithesis of some of the most major trends influencing all of business worldwide. Whether it be Cheese Whiz or Oscar Mayer or Kraft salad dressing or Macaroni and Cheese or Velveeta or Lunchables, this company is definitively on the wrong side of food history, perhaps even on a worse side than its putative acquirer, Heinz.

Think about it. Right now, one of the larger positions we have forActionAlertsPlus.com is WhiteWave (WWAV) . Why? Because unlike, say Crystal Light or Kool-Aid, two Kraft stalwarts, WhiteWave makes plant-based beverages like soy milk and almond milk and walnut milk, all of which are much better for you than those processed drinks. Right now, WhiteWave is expanding its reach by using its natural and organic "Horizon" imprint to attack Lunchables directly with a more wholesome offering that mimics that of the food processor.

Plus, with WhiteWave you get Earthbound -- something actually green, thrown in. I think that Soylent is closer to green than anything Kraft makes, certainly Velveeta, a deeply suspicious product simply because, does it ever need to be refrigerated say, like, a real milk product? I have always thought it was the food to have in the fallout shelter in the rare case thermonuclear war really does break out.

Of course, the real reason why you wanted to avoid Kraft is that it is a pantry name in an era where the millennials are de-pantrying and going for anything that is perceived as being healthier, and the stock professionals are wise to this. They know what grows -- WhiteWave-and what doesn't -- Kraft. They know that WhiteWave has roared from $17.50 two years ago to $42 now, while Kraft has gone from $47 to $61 during that period.

And that's how I don't spend the whole day kicking myself. If you believe in Kraft the whole way through, not only did you underperform but you also probably missed a ton of other giant moves, think Chipotle (CMG) - Get Report vs. McDonald's (MCD) - Get Report.

Therefore, you must ask, was it all worth it for this pay day? The answer? Only if some other company, equally challenged by the farm-to-table movement, like Heinz, would make it worth your while. And even then you would have underperformed for years while you waited for something nearly as good as what happened to WhiteWave to happen to you.
