Breaking News | ON Semiconductor Acquires Synaptics for $7B in All-Stock Deal

ON Semiconductor agreed to acquire Synaptics in an all-stock transaction valued at approximately $7 billion in enterprise value. Synaptics shareholders receive a fixed exchange ratio of 1.350 shares of ON for each Synaptics share, representing a 19% premium to the 10-day volume-weighted average. After close, former Synaptics shareholders will own approximately 12% of the combined company on a fully diluted basis.

The strategic rationale centers on entering edge AI and connectivity markets. Synaptics brings Edge AI compute capabilities via its Astra platform, human-machine interface solutions, and wireless connectivity spanning Wi-Fi, Bluetooth, and GPS. ON claims the acquisition expands its total addressable market by $30 billion to $243 billion by 2030.

ON expects $200 million in annual synergies and projects the deal will become accretive to non-GAAP earnings per share within 18 months of closing. The company also authorized a $6 billion share repurchase program effective January 2026. Transaction close is expected in mid-2027, pending Synaptics shareholder approval and regulatory clearances.

• 18-month EPS accretion timeline - deal becomes dilutive if integration challenges extend this window

• Mid-2027 close - regulatory approval and Synaptics shareholder vote expected through first half of 2027

• $200 million synergy realization - execution on cost synergies will determine whether the 12% dilution to existing holders is offset by earnings growth
