Onsemi Revises Synaptics Acquisition to $123-Per-Share All-Cash Deal

This is a new, forward-looking M&A development rather than market-performance commentary: onsemi and Synaptics explicitly amended their June 25 merger agreement after review of an unsolicited competing proposal. The revised $123-per-share all-cash consideration, approximately $5.7 billion valuation, cash-and-committed-debt funding, expected immediate non-GAAP EPS accretion, and additional synergies materially change the transaction economics for ON and SYNA, supporting high importance and meaningful surprise scores. The announcement date is explicit as October 1, 2026, but the exact real-world announcement time is not stated; the timestamp is therefore normalized to the start of that UTC date with reduced timestamp confidence. This is not a duplicate of the original merger announcement and remains part of existing event 2279 because it advances the pending ON Semiconductor–Synaptics merger storyline. Only ON and SYNA are approved stakeholders; effects on named competitors are indirect and insufficiently specific for conservative approval.
