Diamondback Energy Inc. and Endeavor Energy Resources are reportedly in the late stages of deal talks that would see the shale rivals form a massive company.
A deal between the two oil giants could come as soon as Monday, according to a report in The Wall Street Journal, which cited sources close to the discussions.
The cash-and-stock deal on the table would value privately held Endeavor at roughly $25 billion, with Diamondback
        FANG,
        -1.13%
       stockholders becoming majority holders of the combined group, the sources said. 
A deal would trump ConocoPhillips
        COP,
        -2.41%,
       which was also vying for Midland, Texas-headquartered Endeavor, the sources added. Diamondback, also based in Midland, has a market cap of $27.3 billion, according to FactSet, far below ConocoPhillips’ $133 billion. 
The deal would continue a run of major energy tie-ups, after Chevron Corp.’s
        CVX,
        -1.96%
       $53 billion all-stock buyout of Hess Corp. in October, which came days after Exxon Mobil Corp.’s 
        XOM,
        -2.12%
       $59.5 billion deal to buy Pioneer Natural Resources Co. 
        PXD,
        -1.96%.
       
Last month,  Southwestern Energy Co.
        SWN,
        -0.77%
       and Chesapeake Energy Corp.
        CHK,
        -0.57%
       agreed to form a natural gas giant in a $7.4 billion tie-up.
