ON Semi (ON) is to buy Synaptics (SYNA) for USD 123/shr cash in a revised deal

A revised all-cash bid changes the frame from whether a deal happens to where it prices, and the standard read in such re-runs is that the target trades up toward the new consideration while the acquirer absorbs the dilution and leverage questions. Onsemi's form has been that of a disciplined consolidator in power and sensing silicon rather than a serial large-cap acquirer, so a move into Synaptics' edge-AI and human-interface franchise marks a broadening of scope that deserves attention on strategic fit and integration track record. The distinction worth drawing is between a revision driven by competing interest or board resistance, which tends to close near the cash terms, and one papering over diligence issues, where deal spreads stay wide. An all-cash structure removes the collar and ratio-risk questions that complicate stock deals, so the spread narrows to timing and regulatory risk. The follow-ons are the merger agreement detail, any go-shop or break-fee terms, the financing plan and its read-through to the acquirer's credit, and antitrust posture given overlap in automotive and IoT silicon.
