Gatorade and Pepsi just don't mix well.

The Wall Street Journal

reported in its Friday edition that

PepsiCo

(PEP) - Get Report

wasn't able to buy

Quaker Oats

(OAT)

, maker of Gatorade and other consumer products. The paper said the two companies could not agree on a price.

Pepsi had been holding talks to acquire Quaker Oats for about $14 billion in stock.

PepsiCo is believed to have offered slightly more than two of its shares for each Quaker share, which would value Quaker at close to $100 a share, according to a report yesterday. Quaker closed Thursday at $82.25, while PepsiCo closed at $47.06 in

New York Stock Exchange trading.
