Disclosure: The portfolio's systems may trade the securities discussed; coverage does not mean a position is open.
Synaptics closed at $94.72 on Tuesday, September 8, about $1.24 below the value of the onsemi shares promised in its pending acquisition. We would pass on a new position at that comparison. A buyer accepts the risk that the deal fails and that onsemi's shares fall before the exchange happens. The small difference does not compensate us enough for those risks. [1][2]
The business has a reason for customers to stay
Synaptics makes chips and software that help devices process information, connect wirelessly and respond to touch, sound and images. Its place in AI is partly inside the device itself, doing more computation locally. Winning a place in the design matters because replacing an established supplier can require expensive engineering work. [3][4]
Synaptics describes customer-specific customization and long development cycles as barriers to copying its products. Our reading is that integration can make a successful customer relationship durable. But those same switching costs protect competitors when they win the design first. Winning also does not guarantee sales: the customer's product still has to succeed. [4]
That is a useful advantage, with limits. Synaptics says its average selling prices have historically declined. It has reasons for customers to stay, but must keep earning the next generation of business. [4]
Operating progress is only part of the purchase
Core IoT revenue grew 43.1% in fiscal 2026, including a contribution from the Broadcom transaction. That figure cannot establish how much more customers bought because of AI alone. Companywide gross margin stayed at 44.7%. [5]
There is also evidence in favor of the business. Synaptics generated $149.4 million of operating cash, and its annual operating loss narrowed. The company is making operating progress. Our decision does not depend on predicting that this progress will stop. [5][6]
The merger adds another business to the assessment. Each eligible Synaptics share would become 1.350 onsemi shares. Using onsemi's $71.08 close from the same September 8 session gives $95.958 of consideration, about $95.96 per SYNA share. Subtracting $94.72 leaves $1.238, or 1.31% of the purchase price, before costs. [1][2]
That difference is a snapshot, not a locked return. Earning it requires completion, an unchanged onsemi share price and costs that do not consume it. A higher onsemi price could produce much more upside; a lower one could erase the difference. Synaptics expected completion in mid-2027, subject to stockholder and regulatory approvals. Neither completion nor that timing is assured. [2]
What would change our view
Our hypothesis is that this small difference does not adequately reward a new buyer who has no separate reason to own onsemi. Strength of belief: medium. The arithmetic is clear, while the eventual outcome depends on a second company's stock and an unfinished transaction.
An investor who already wants onsemi may reasonably accept the deal risk. If onsemi rises and the acquisition completes, passing on SYNA could prove costly. A wider difference between SYNA's price and the offered shares, or materially reduced closing uncertainty, would prompt a fresh assessment. A materially improved exchange offer would invalidate this comparison. We will review the published terms and status on September 30, 2026, our own review date, and earlier if material terms change. This is a status check, not a promised closing date or a deadline for earning a return.
The call
Stance: observation
Level: The isolating trigger for a new comparison is a materially improved exchange offer.
Horizon: 2026-09-30
Checkpoint: 2026-09-30
What closes the file: A materially improved exchange offer would invalidate this comparison.
