ON Semiconductor Agrees to Acquire Synaptics for $7B in All-Stock Deal (NASDAQ:ON)

ON Semiconductor Corporation (NASDAQ: ON) announced a definitive agreement on June 25, 2026 to acquire Synaptics Incorporated (NASDAQ: SYNA) in an all-stock transaction valued at $7 billion, the largest acquisition in the Scottsdale-based chipmaker's history. Shares of ON gained 6.74% on Tuesday, June 30, 2026, closing at $94.54.

Deal Terms

• Transaction size: $7 billion, structured entirely as an all-stock agreement.
• Target: Synaptics Incorporated, a developer of human interface solutions and IoT connectivity chips.
• Structure: All-stock, meaning no cash outlay at closing but dilution to existing ON shareholders.
• Announcement date: Thursday, June 25, 2026, per the company's investor presentation.
• Source: ON Semiconductor published a slide deck in conjunction with the merger announcement on June 30, 2026.

Why It Matters

The all-stock structure means ON avoids a significant cash draw but issues new equity to Synaptics shareholders, directly affecting the ownership composition of the combined company. Synaptics brings human interface, IoT connectivity, and edge AI capabilities to ON's existing power and analog semiconductor portfolio, broadening the product lines available to automotive and industrial customers.

At $7 billion, the deal represents a material commitment relative to ON's market capitalization of $36.8 billion at the time of announcement. The transaction signals a strategic shift toward higher-complexity, software-adjacent chip solutions rather than purely discrete power devices, according to the company's merger presentation materials.

Wall Street View

Analyst consensus on ON as of June 1, 2026 stood at 17 Buy ratings, 5 Strong Buy ratings, and 21 Hold ratings, with no Sell or Strong Sell recommendations, reflecting a broadly constructive stance ahead of the deal announcement. No specific new price targets tied directly to the Synaptics acquisition were available in the source data at the time of publication.

Investor Takeaway

ON Semiconductor's $7 billion all-stock acquisition of Synaptics marks a pivotal strategic expansion, adding IoT and human interface capabilities to its core power semiconductor business. The all-stock structure preserves the company's balance sheet liquidity while introducing shareholder dilution, a trade-off investors will weigh against the long-term portfolio benefits. With a broadly Buy-leaning analyst consensus already in place, the market's initial 6.74% move on June 30 suggests initial investor reception was positive, though integration execution at this scale will be a key variable to monitor.
