Onsemi Rewrites Synaptics Deal as $5.7B Cash Offer
Onsemi and Synaptics revised their merger deal to a $5.7B cash offer of $123 per share, replacing the earlier all-stock agreement. The deal, expected to close by mid-2027, combines Onsemi's power and sensing semiconductors with Synaptics' edge-computing and connectivity products. The change followed a rival proposal, with Synaptics' board approving the amended terms. Onsemi will use cash on hand and committed financing for the acquisition.
