NEW YORK, May 30, 2026, 12:02 EDT
Atomera Inc. shares sank 10.7% Friday to finish at $9.98, erasing some gains after a volatile week. The stock ended the shortened week up about 8% from last Friday. Over the four sessions, Atomera jumped 31.1% Tuesday, slipped Wednesday, edged higher Thursday, and then gave back ground Friday.
Why Atomera’s stock is in focus now: trading was anything but normal this week. U.S. markets were closed Monday, May 25, for Memorial Day, according to Nasdaq’s holiday schedule. The next regular session after Friday’s drop lands Monday, June 1.
Atomera moved sharply on Friday while the broad market traded higher. The S&P 500 and Nasdaq Composite both added 0.2% Friday, with the Nasdaq finishing up 2.4% for the week, AP market data showed. Swings in Atomera were far bigger, showing how small tech stocks can react to slight news and heavy sector sentiment.
Chip stocks set the tone. The PHLX Semiconductor Index rose 5.14% over the last five sessions to finish Friday at 12,829.38, MarketWatch and Nasdaq data show. Atomera’s stock was much more volatile than the index it tends to follow.
No new company news hit Friday. The most recent update on Atomera’s press-release page was its first-quarter results from May 5. The company’s events page had nothing listed, and no dates for future events.
Atomera’s most recent numbers are for the first quarter. The company posted revenue of $11,000 and a net loss of $6.1 million, or 17 cents per share, in the quarter ending March 31. Cash, cash equivalents and short-term investments came in at $41.1 million.
Atomera’s balance sheet got a boost, but dilution followed. In its quarterly filing, the company said it raised cash selling five million shares at $5.00 each in a registered direct offering. Another 1.3 million shares sold through an at-the-market program, at about $2.47 on average. Atomera said it expects this working capital to last at least 24 months.
Adoption is still the focus for Atomera, not sales yet. The company licenses its Mears Silicon Technology, or MST, a thin-film process that it claims boosts transistor performance and lowers power use. CEO Scott Bibaud said May 5 that Atomera had made “excellent progress” toward getting MST into gate-all-around manufacturers. That’s a new kind of transistor design for advanced chips. Atomera
Atomera’s competitive focus is tight. The company is not looking to sell finished chips against Nvidia or Micron. Instead, Synopsys is the closer peer, especially as both took part in Atomera’s April GaN work. GaN, or gallium nitride, is common in RF and power chips. Rahul Deokar, Synopsys executive director of product management for Manufacturing Solutions, said the teams are pushing ahead on “advancing GaN TCAD simulations.” That’s software for modeling semiconductor devices before fabrication.

But the risk remains. Atomera so far has booked only small amounts of engineering services and licensing revenue, and the company warned that customers with licenses or joint development deals might not move to royalty-based manufacturing licenses. Royalties depend on later product use or sales. If customer tests drag out, shareholders have to weigh cash burn and the risk of dilution if Atomera issues more shares.
Week ahead: Traders are watching to see if Friday’s drop in Atomera was just a reset or signals more downside. The stock traded between $12.37 on Tuesday and a low of $9.66 on Friday. There’s no company event on the calendar. Attention now turns to Monday’s volume and if the broader semiconductor rally can lift smaller names like Atomera.
