ON Semiconductor fell on Friday after announcing a $7B all-stock deal to acquire Synaptics, erasing most of its 119% year-to-date rally in a single session.
The company is buying Synaptics to push into what it calls physical AI a.k.a. systems capable of sensing and making decisions in real time, including robots, drones, and autonomous vehicles.
Management says the deal expands ON's total addressable market by $30B, bringing the total to $243B by 2030. The transaction is expected to close in mid-2027 and generate $200M in annual synergies within 18 months of closing.
CEO Hassane El-Khoury defended the deal, calling it "complementary to everything we have done on a very strong foundation."
Investors weren't convinced. The sell side split on the deal, with some analysts lifting price targets on synergy potential while others downgraded the stock citing integration risk running into 2027.
Synaptics shares edged up slightly, reflecting the 19% premium embedded in the exchange ratio of 1.35 ON shares per SYNA share.
ON's drop landed inside a broader chip sector pullback driven by separate concerns. Micron Technology, Sandisk, and Western Digital were all in the red.
Nvidia, Broadcom, AMD, Intel, Marvell, and Qualcomm all moved lower as well.
The memory-driven selloff stemmed from fears that rising chip prices are starting to squeeze the broader tech industry.
Apple raised prices on some products to offset surging memory costs. Microsoft raised prices on Xbox consoles, stoking concern that higher component costs passed through to consumers could eventually dampen demand.
AMD and Intel's declines appeared unrelated to ON's deal, tracking instead with sector-wide profit-taking and macro pressure. The VIX sat at 18.89, within its normal range, suggesting the pullback reflects positioning rather than systemic stress.
For investors trying to read the tape on chip stocks, history offers some perspective. Fundstrat's Tom Lee studied 17 prior single-day drops of at least 6% in the semiconductor sector since 2011 and found median one-month gains of 12% and median three-month gains of 23%, each with an 88% win rate.
The VanEck Semiconductor ETF remains up 73% for the year despite the recent turbulence.
