In the wake of a leadership reshuffling and amid lingering financial troubles, publicly traded Nauticus Robotics, a Webster-based developer of subsea robots and software, has netted more than $12 million in a second tranche of funding.

The more than $12 million in new funding includes a $9.5 million loan package.

Nauticus says the funding will accelerate certification of the company’s flagship Aquanaut robot, which is being prepared for its inaugural mission — inspecting a deep-water production facility in the Gulf of Mexico that’s owned by a major oil and gas company.

The new funding comes several weeks after the company announced a change in leadership, including a new interim CEO, interim chief financial officer, and lead general counsel.

Former Halliburton Energy Services executive John Gibson, the interim CEO, became president of Nauticus last October and subsequently joined the board. Gibson replaced Nauticus founder Nicolaus Radford in the CEO role. Radford’s LinkedIn profile indicates he left Nauticus in January 2024, the same month that Gibson stepped into the interim post.

Radford founded what was known as Houston Mechatronics in 2014.

Victoria Hay, the new interim CFO at Nauticus, and Nicholas Bigney, the new lead general counsel, came aboard in the fourth quarter of 2023.

“We currently have the intellectual property, prototypes, and the talent to deliver robust products and services,” Gibson says in a news release. “Team Nauticus is now laser-focused on converting our intellectual property, including both patents and trade secrets, into differentiated solutions that bring significant value to both commercial and government customers.”

A couple of weeks after the leadership shift, the NASDAQ stock market notified Nauticus that the average closing price of the company’s common stock had fallen below the $1-per-share threshold for 30 consecutive trading days. That threshold must be met to maintain a NASDAQ listing.

Nauticus was given 180 days to lift its average stock price above $1. If that threshold isn’t reached during that 180-day period, the company risks being delisted by NASDAQ. The stock closed February 6 at 32 cents per share.

The stock woes and leadership overhaul came on the heels of a dismal third-quarter 2023 financial report from Nauticus. The company’s fourth-quarter 2023 financial report hasn’t been filed yet.

For the first nine months of 2023, Nauticus reported an operating loss of nearly $20.9 million, up from almost $11.3 million during the same period a year earlier. Meanwhile, revenue sank from $8.2 million during the first nine months of 2022 to $5.5 million in the same period a year later.

Nauticus went public in September 2022 through a SPAC (special purpose acquisition company) merger with New York City-based CleanTech Acquisition Corp., a “blank check” company that went public in July 2021 through a $150 million IPO. The SPAC deal was valued at $560 million when it was announced in December 2021.

Nauticus recently hired investment bank Piper Sandler & Co. to help evaluate “strategic options to maximize shareholder value.”

One of the strategic alternatives involves closing Nauticus’ previously announced merger with Houston-based 3D at Depth, which specializes in subsea laser technology. When it was unveiled last October, the all-stock deal was valued at $34 million.

Houston healthtech leader launches clinical trial for innovative anxiety-treating device

making waves

Houston-based Nexalin Technology’s proprietary neurostimulation device will move forward with a new clinical trial evaluating its treatment of anxiety disorders and chronic insomnia in Brazil.

The first of Nexalin’s Gen-2 15-milliamp neurostimulation devices have been shipped to São Paulo, Brazil, and the study will be conducted at the Instituto de Psiquiatria university hospital (IPq-HCFMUSP). The shipments aim to support the launch of a Phase II clinical trial in adult patients suffering from anxiety and insomnia, according to a news release.

“Brazil is an important emerging market for mental health innovation, and this collaboration marks our first IRB-approved study in the region,” Mike White, CEO of Nexalin, said in the release.

The study will be led by Dr. Andre Russowsky Brunoni, who specializes in neuromodulation and interventional psychiatry. He currently serves as director of the interventional psychiatry division at IPq-HCFMUSP and this summer will join UT Southwestern in Dallas and its Peter O’Donnell Jr. Brain Institute as a professor of psychiatry.

The Phase II study plans to enroll 30 adults in São Paulo and assess the efficacy of Nexalin’s non-invasive deep intracranial frequency stimulation (DIFS™) of the brain in reducing anxiety symptoms and improving sleep quality, according to the company. Using the Hamilton Anxiety Rating Scale (HAM-A), the trial’s goal is a reduction in anxiety symptoms, and assessments of sleep onset latency, total sleep time, overall sleep quality, depressive symptoms and clinical impression of improvement. The company plans to share results in a peer-reviewed scientific journal.

“Anxiety and insomnia are very common conditions that often occur together and cause significant distress,” Brunoni added in the news release. “In this study, we are testing a new, non-invasive brain stimulation technology that has shown promising results in recent research. Our goal is to offer a safe, painless, and accessible alternative to improve people’s well being and sleep quality.”

The Nexalin Gen-2 15-milliamp neurostimulation device has been approved in China, Brazil, and Oman.

The company also enrolled the first patients in its clinical trial at the University of California, San Diego, in collaboration with the VA San Diego Healthcare System for its Nexalin HALO, which looks to treat mild traumatic brain injury and post-traumatic stress disorder in military personnel and the civilian population. It also recently raised $5 million through a public stock offering. Read more here.

Texas university to lead new FAA tech center focused on drones

taking flight

The Texas A&M University System will run the Federal Aviation Administration’s new Center for Advanced Aviation Technologies, which will focus on innovations like commercial drones.

“Texas is the perfect place for our new Center for Advanced Aviation Technologies,” U.S. Transportation Secretary Sean Duffy said in a release. “From drones delivering your packages to powered lift technologies like air taxis, we are at the cusp of an aviation revolution. The [center] will ensure we make that dream a reality and unleash American innovation safely.”

U.S. Sen. Ted Cruz, a Texas Republican, included creation of the center in the FAA Reauthorization Act of 2024. The center will consist of an airspace laboratory, flight demonstration zones, and testing corridors.

Texas A&M University-Corpus Christi will lead the initiative, testing unstaffed aircraft systems and other advanced technologies. The Corpus Christi campus houses the Autonomy Research Institute, an FAA-designated test site. The new center will be at Texas A&M University-Fort Worth.

The College Station-based Texas A&M system says the center will “bring together” its 19 institutions, along with partners such as the University of North Texas in Denton and Southern Methodist University in University Park.

According to a Department of Transportation news release, the center will play “a pivotal role” in ensuring the safe operation of advanced aviation technologies in public airspace.

The Department of Transportation says it chose the Texas A&M system to manage the new center because of its:

  • Proximity to major international airports and the FAA’s regional headquarters in Fort Worth
  • Existing infrastructure for testing of advanced aviation technologies
  • Strong academic programs and industry partnerships

“I’m confident this new research and testing center will help the private sector create thousands of high-paying jobs and grow the Texas economy through billions in new investments,” Cruz said.

“This is a significant win for Texas that will impact communities across our state,” the senator added, “and I will continue to pursue policies that create new jobs, and ensure the Lone Star State continues to lead the way in innovation and the manufacturing of emerging aviation technologies.”
