Shares of Darling International (NYSE:DAR) plunged 4% Tuesday after Moody's downgraded the rendering and biodiesel specialist's Corporate Family Rating.

To explain the move, Moody's cited weakened credit metrics and execution risks associated with Darling's pending (and incredibly ambitious) $2.17 billion acquisition of Vion Ingredients. 

However, as the Fool's Steve Symington insists in the following video, while Moody's was right to recognize the risk, investors shouldn't misinterpret its cautiousness as a reason to believe Darling has bitten off more than it can chew.
