Momenta downgraded to Equal Weight from Overweight at Wells Fargo 09:39 MNTA Wells Fargo analyst Yanan Zhu downgraded Momenta (MNTA) to Equal Weight from Overweight with a price target of $52.50, up from $48, after the company announced plans to be acquired by Johnson & Johnson (JNJ) for $52.50 per share. Zhu believes the $6.5B acquisition value is consistent with the broad opportunity represented by Momenta's lead FcRn asset nipocalimab across various autoantibody-driven diseases given its best-in-class potency in antibody reduction.
