NEW YORK, June 18, 2026, 16:03 (EDT)
- Qnity Electronics climbed 7.2% to $168.07 late Thursday on volume of around 2.9 million shares.
- That follows a broader chip rally. The iShares Semiconductor ETF jumped 7.4%. Shares of materials player Entegris climbed 13.6%.
- U.S. markets will shut Friday for Juneteenth, cutting the week short ahead of the extended weekend.
Qnity Electronics traded sharply higher Thursday as buyers moved into semiconductor suppliers in a broad chip rally. The recently spun-off materials company hovered near its session peak with markets set to close for the Juneteenth holiday.
The stock traded at $168.07, up $11.35, or 7.2%, late. Market cap was close to $35.4 billion. Shares changed hands at a trailing P/E of about 54, meaning investors paid 54 times the company’s past earnings for each share.
Qnity is in a quieter part of the AI story, dealing with chipmaking materials, packaging, interconnects and thermal management. It’s not as high profile as Nvidia or Intel but still linked to the broader AI buildout. When money moves into semiconductors, names like Qnity can jump, especially if the sector is leading gains that day.
U.S. stocks climbed Thursday, Reuters said, as semiconductors outperformed and oil dropped. The move followed an interim U.S.-Iran deal that gave investors some relief. Cantor’s Eric Johnston said the rally was about “continued excitement around the semiconductor sector” and fresh thinking on oil and the Fed. Reuters
Semi stocks traded higher Thursday. The iShares Semiconductor ETF added 7.4%. Entegris, which competes more directly with Qnity in materials and process supply, jumped 13.6%—even more than Qnity. The action suggested investors were buying into the broader advanced chip supply chain, not reacting just to a Qnity product update.
Qnity said in a June 16 company update that it’s targeting the use of Kalrez sealing products in industrial valves for the semiconductor, chemical and energy sectors. Brian Ammons, VP and GM of Kalrez Sealing Solutions, said the products are designed to cut fugitive emissions and make seals last longer.
This isn’t a fresh AI chip order. But it lines up with Qnity’s focus—put high-end materials from semiconductors into any job that needs strong heat, chemical resistance, or reliability. Right now, investors are willing to pay for this kind of option.
Qnity’s numbers for the May quarter were strong. The company posted first-quarter net sales of $1.315 billion, an 18% jump from last year, with adjusted earnings per share at $1.08. Qnity also bumped up its 2026 forecast, now looking for net sales of $5.225 billion to $5.375 billion. CEO Jon Kemp said the firm is “stacking chips and building more complex” systems.

The setup carries risks. Qnity’s filings mention geopolitical uncertainty, trade curbs, international risks and potential spin-off costs. The stock’s valuation means there isn’t much room to miss if AI spending slows or chip customers cut orders. A pullback in semis would probably show up in suppliers first.
Traders had to deal with some market-structure quirks on Thursday. NYSE’s calendar lists all its markets closed Friday for Juneteenth. The normal core session finished at 4 p.m. Eastern, so investors needed to make moves ahead of a three-day break.
