NEW YORK (TheStreet) -- The Valspar Corp. (VAL - Get Report) stock is advancing 24.04% to $103.98 on heavy trading volume on Monday afternoon after the Minneapolis-based paint company agreed to be acquired by its competitor The Sherwin-Williams Co. (SHW) in a deal valued at $11.3 billion.

Shares of Sherwin-Williams are down 5.63% to $272.45 this afternoon.

"Valspar is a very proud company. It's been around forever... for them to be able to succumb to Sherwin is a recognition that they wanted to do what was right for shareholders," TheStreet's Jim Cramer, portfolio manager of the Action Alerts PLUS charitable trust portfolio, said.

On Sunday, the companies announced the transaction, which is expected to close by the end of the 2017 first quarter and is subject to shareholder and regulatory approval.

Cleveland-based Sherwin-Williams will pay Valspar shareholders $113 per share, representing a 35% premium to Valspar's stock closing price on Friday, according to Deutsche Bank analysts.

The offer is expected to be the best Valspar will receive after being an acquisition target in the paint industry for some time, Deutsche Bank said in an analyst note this morning.

Annual synergies are estimated to reach $320 million within two years after closing, Sherwin-Williams CEO John Morikis said in a statement.

"We expect this transaction to be immediately accretive excluding one-time costs and meaningfully enhance our cash flow generation profile," Morikis added.

So far today, 11.16 million shares of Valspar have exchanged hands, compared with its average daily volume of 657,716 shares.

Separately, Valspar has a "buy" rating and a letter grade of B at TheStreet Ratings because of the company's good cash flow from operations and expanding profit margins.
