Atomera shares fell to a 52-week low after the company said a project with STMicroelectronics won't proceed.
The stock was down 32% to $2.87 in early afternoon trading on Wednesday, and touched an intraday low of $2.48. Shares are down about 75% this year.
A 2023 commercial license agreement allowed STMicroelectronics to install Atomera's Mears Silicon Technology at its facilities, and authorized the manufacturing and distribution of MST-enabled products.
In a blog post on Tuesday Atomera discussed some technical aspects of the collaboration. That included a potential change in the device's architecture that would have taken too long for STMicroelectronics to meet its 300mm BCD110 production time frame.
"In short, ST has decided to take BCD110 to market without the MST improvement and currently doesn't have a plan for a further product variant with MST leaving us without a line of sight to royalty," Atomera said. "ST has reinforced that they will continue to work with us on the other technology areas in which we are engaged."
