NEW YORK (TheStreet) -- Post Holdings (POST) - Get Report stock closed higher by 1.41% to $76.76 on Thursday, after the food company was initiated with an "overweight" rating and a $90 price target at KeyBanc Capital Markets.

Analysts see a 20% upside to the stock because of improving free cash flow, potentially higher synergies related to the MOM Brands acquisition, rising margins in the active nutrition segment and strong long-term earnings potential from its Michael Foods unit.

"POST has established a clear pattern of under-promising and over-delivering on prior synergy targets; we believe MOM Brands is ripe with synergy upside and see $100M+ given the identical nature of the MOM and POST legacy cereal businesses, driving solid mid-20%+ segment margins," KeyBanc analysts explained in a note released before today's market open.

Post has made 11 deals in three years and integration efforts are starting to pay off with a significant drop in general and administrative costs.

"We believe these dynamics combined with several segment-specific catalysts should conservatively clear a path to just under $1B in organic EBITDA over the next three years (ex-M&A)," analysts added.

Separately, Post has a "buy" rating and a letter grade of B- at TheStreet Ratings because of the company's robust revenue growth, solid stock price performance, good cash flow from operations, expanding profit margins and notable return on equity.
