NEW YORK (TheStreet) -- Shares of Molson Coors Brewing (TAP) - Get Report are tumbling 5.22% to $92.98 on heavy trading volume late Wednesday afternoon after the Wall Street Journal reported SABMiller (SBMRY) has halted its efforts to integrate its operations with Anheuser Busch InBev's (BUD).

Molson Coors is slated to acquire SABMiller's 58% stake in their venture, MillerCoors, for $12 billion as part of SABMiller's efforts to win regulatory approval for the AB InBev deal. 

The suspension of the companies' integration comes a day after AB InBev sweetened its takeover offer for SABMiller. 

SABMiller is reviewing the revised offer and will consider factors such how a weaker pound has eroded the cash portion of the deal and what the company's valuation would be if the acquisition doesn't close, according to the Journal.

About 15.28 million shares of Molson Coors have been traded so far today, well above its average trading volume of roughly 1.87 million shares per day. 

Separately, TheStreet Ratings team rates the stock as a "buy" with a ratings score of B+.

Molson Coors' strengths such as its increase in net income, largely solid financial position with reasonable debt levels by most measures, expanding profit margins, good cash flow from operations and solid stock price performance outweigh the fact that the company has had somewhat disappointing return on equity.
