Defense contractor L3Harris Technologies presented a mixed picture as it reported fourth-quarter earnings and issued confusing guidance. Fourth-quarter adjusted earnings of $2.86 a share topped the $2.76 a share analysts had forecast. Revenue across all of the defense contractor’s business segments fell short of forecasts, with the exception of its integrated mission systems unit, which brought in $1.72 billion in the quarter, topping analysts’ calls for $1.64 billion.
