Normal[GroupBy[Join[data1, data2], First -> Last, Sequence @@ # &]] /. {Rule -> List} SplitBy[Sort[Join[data1, data2]], First] /. z : {{_List, _Integer} ..} :> {First[First[z]], Sequence @@ z[[All, 2]]} lots of ways ;-)

Normal[GroupBy[Join[data1, data2], First -> Last, 
       Sequence @@ # &]] /. {Rule -> List}


SplitBy[Sort[Join[data1, data2]], First] /. 
 z : {{_List, _Integer} ..} :> {First[First[z]],  Sequence @@ z[[All, 2]]}

lots of ways ;-)
