ON Semiconductor’s all-stock $7 billion acquisition of Synaptics is expected to close in mid-2027, offering $200 million annual synergies but diluting equity by roughly 12% and pushing meaningful earnings accretion to 2028-29. TD Cowen cut onsemi to Hold and lowered its price target to $110, citing deal complexity and limited margin savings.
ON Semiconductor agreed to acquire Synaptics in an all-stock transaction valuing the target at an enterprise value of about $7 billion. The deal is slated to close in mid-2027, pending shareholder and regulatory approvals.
TD Cowen downgraded onsemi from Buy to Hold and trimmed its price target to $110, arguing that the acquisition adds complexity and dilutes the pure-play automotive and datacenter investment narrative.
Management projects $200 million in annual cost synergies primarily from operating expense reductions, while analysts estimate roughly 12% equity dilution and see meaningful earnings accretion only in 2028 or 2029 due to integration and margin recovery challenges.
