KBR unveils name, branding for new government services spinoff

new identity

Houston-based KBR Inc.'s new Mission Technology Solutions unit officially has a name.

The previously announced government services spinoff, which until now has been nicknamed SpinCo, will now be known as Trinzic. The company said in a news release that the name was inspired by the word intrinsic, "reflecting essential, built-in capabilities and deep expertise operating in some of the world’s most complex and mission-critical environments."

New York-based firm Siegel + Gale developed the company's new brand. In addition to the new name, the company shares that its new logo will feature a stylized letter N, with brand colors in orange and gray.

“Trinzic represents who KBR Mission Tech has always been at our core: an essential partner bringing innovation and trusted execution to the missions that matter most,” Stuart Bradie, KBR President and CEO, said in the release. “The new Trinzic brand represents both our strong heritage and the tremendous opportunity ahead. Our teams aim to deliver solutions that address some of the world’s most critical national priorities every day, and this new identity captures the purpose-driven culture and mission focus that we expect to continue to define the company moving forward.”

KBR expects the spin-off to be completed in January 2027. At that time, Trinzic will operate as an independent, publicly traded company that will focus on technology and engineering services for the space and national security sectors.

KBR will remain a separate publicly traded company that will focus on sustainable technology and services to support the energy transition. KBR first announced the spinoff plans in October 2025.

Last month, KBR announced two C-suite hires for Trinzic, or what was then known as SpinCo.

Michael LaRouche will serve as Trinzic's inaugural president and CEO. LaRouche is currently CEO of Serco North America, a Virginia-based government services contractor. Nicholas Veasey, current CFO of Virginia-based MAG Aerospace, was named Trinzic's CFO. Bradie will remain chairman, president and CEO of KBR.

Rice lands $19 million grant to build AI-driven quantum materials lab

Quantum Boost

Rice University has received a $19.9 million award from the National Science Foundation to increase the production of quantum and electronic materials by using a combination of artificial intelligence, cloud-based labs and robotics.

The four-year project will create a remote and automated research platform that aims to accelerate discovery and the testing process, according to Rice. The aptly titled project, "Revolutionizing AI-Driven Autonomous Experimentation for Next-Generation Semiconductor Synthesis” (READINESS), will be led by Rice materials scientist Jun Lou, who serves as principal investigator. SUNY Polytechnic Institute and the University of Texas at Austin will collaborate with Rice on the project.

At first, READINESS will focus on two-dimensional materials, oxide semiconductors and diamond thin films that can support emerging technologies, like quantum devices.

READINESS is one of 20 projects selected for the NSF's Programmable Cloud Laboratories Test Bed initiative, which aims to provide more U.S. researchers with access to automated scientific tools.

Additionally, the project aligns with the Department of Energy’s Genesis Mission, which recently selected four projects from Houston universities and companies, including two from Rice. The national initiative aims to unite government, industry, academia and philanthropy to lead to breakthroughs in energy, scientific discovery and national security.

READINESS will offer more advanced lab systems remotely via a cloud interface to assist startups, other research groups, and companies that don’t have the resources, staffing or equipment to produce quantum materials and advanced electronics. READINESS will also allow researchers to simulate experiments via virtual experiments or digital twins before they conduct the physical experiment.

Rice says this will be particularly useful in quantum materials research, which is often met with barriers— like the adjustments of chemical composition, gas flow, pressure, and temperature—that can change the properties of a material.

“This project will give researchers access to capabilities that have traditionally been available only in a handful of laboratories,” David Sholl, executive vice president for research at Rice, said in a news release. “By lowering those barriers, READINESS can accelerate discovery and expand who can participate in cutting-edge materials research.”

Additionally, the project’s AI aspect will offer recommendations for new tests, recognize safety limits and analyze results to assist researchers.

“Responsible AI should complement researchers’ capabilities rather than replace their judgment,” Luay Nakhleh, Dean of Rice’s George R. Brown School of Engineering and Computing, added in the release. “READINESS embodies this principle by combining automated systems with transparency, safeguards and human oversight at critical decision points.”

READINESS’ lab will be based out of Rice’s Ralph S. O’Connor Building for Engineering and Science. Partner sites will also contribute equipment, expertise and workforce development programs, according to Rice.

Ultimately, READINESS aims to elevate the speed, reliability and reproducibility of experiments, and to promote access to automated scientific tools for U.S. researchers.

“Our goal is to create a laboratory that researchers from across the country can use to produce advanced electronic and quantum materials on demand,” Lou added in the release. “By integrating robotics, AI and digital twins, we aim to learn from every experiment and shorten the pathway from scientific discovery to practical technology.”
