Houston-based Pyrophyte Acquisition Corp., a “blank check” SPAC, plans to merge with Canadian quartz silica producer Sio Silica Corp. in a deal valued at more than $700 million.

The companies say the deal carries an enterprise value of $708 million and an equity value of $758 million.

Sio is sitting on a potential supply of 15.2 billion metric tons of high-purity quartz silica, a material needed to produce energy transition technologies such as photovoltaics, solar panels, semiconductors, batteries, and other electronics. Proceeds from the merger will be earmarked for construction of the first phase of Sio’s silica extraction and processing facility near Winnipeg, Manitoba.

“We searched long and hard for the right candidate to combine with Pyrophyte and its energy transition mission. Sio fulfilled all our criteria,” Bernard Duroc-Danner, chairman of Pyrophyte, says in a news release. “We are proud to join Sio on its journey to supply what is becoming in many countries around the world one of the most important strategic minerals for the world’s energy transition.”

In 2021, Pyrophyte’s stock began trading on the New York Stock Exchange in an IPO valued at $201.25 million. Since then, it’s solely been a special purpose acquisition company (SPAC) without any business operations. Typically, a SPAC aims to acquire or merge with a private company that boasts a promising business model.

Duroc-Danner is former chairman, president, and CEO of Houston-based oilfield equipment and services company Weatherford International Ltd.

Calgary, Alberta-based Sio says high-purity quartz silica will represent a $30 billion global market opportunity by 2030. Among the products that rely on silica are semiconductors, solar panels, photovoltaic (solar) cells, optical fibers, and batteries.

Once the deal closes, the combined company will operate as Sio Silica Inc., whose stock will be traded on the New York Stock Exchange. Sio’s CEO, Feisal Somji, will lead the newly formed company.

The deal has been approved by Sio’s and Pyrophyte’s boards but still must be endorsed by the companies’ shareholders.

Q&A: Houston robotics entrepreneur on IPO, military innovation, and more

automation nation

Almost a decade ago, Nicolaus Radford founded a robotics company that automated underwater operations for heavy industry customers. Now, the company provides its robotics-as-a-service business to customers across industry, providing key analytics, risk-managed monitoring, and emission-reducing service.

Nauticus Robotics (Nasdaq: KITT) went public via SPAC last year, and Radford, CEO and founder, sat down with InnovationMap earlier this year to share the unique challenges he faced with the IPO, the company's partnerships with the United States Marine Corps, and more. Check out the shortened Q&A below and head to InnovationMap for the full conversation.

InnovationMap: Tell me about life after IPO. What’s been surprising for you leading your company through the transition and now on the other side of IPO?

Nicolaus Radford: I'll tell you what, it’s the hardest thing I ever did in my professional career by a factor of 10. It was a very exceptionally challenging period of time. It took a long to complete the transaction, and the market was just changing under our feet. Rules were and regulations were changing — were we grandfathered in or were we not?

I'm part of some business organizations and, and some of those confidential relationships have turned into friendships. And a couple of them call me and they're like, “we're really worried. We think this is going to be we don't know if you're going to get it done. And we just want you to be aware that you're not you may not get it done.” It is a little scary because once you engage in it, you're running quite a tab with bankers and law firms and all sorts of things. And if you don't complete the deal, it just might kill the company.

But we did it. We were one of a few people last year to actually get a deal over the line. I'm very proud of that. I think it speaks to the quality of the deal that we had. The macro economic environment was exceptionally difficult. It remains to be very difficult today. But we had strong backing from our strategic investors and our partners that were already on the cap table. They put a tremendous amount of money into the deal.

You know, I look back on it and it's, you know, ringing the Nasdaq bell when we listed, and giving that speech at the podium — it was a surreal moment. I remember when I was standing there looking at the Nauticus logo on the seven-story Nasdaq tower, having as many people in the company as we could bring, and just sharing that moment with all of them.

I was excited but cautious at the same time. I mean, the life of a CEO of a public company at large, it's all about the process following a process, the regulations, the administration of the public company, the filings, the reportings — it can feel daunting. I have to rise to the occasion to tackle that in this the next stage of the company.

IM: You’re working with the military on a project that adapts Nauticus tech for Marine Corps use. What’s it been like working with the military on this project?

NR: We've probably worked with military interests for the last six years, but all of the things that we have been doing have been extremely confidential and hush. Now we've been able to work with customers that have a stronger public facing persona, and the Defense Innovation Unit is one of those.

Their charter is it's quite literally looking for commercial technology and adapting that towards military applications, and so it's been nice to be able to show the utility and the application of of a lot of our technology and what we've been working on for so long as it's applied on a broader scale to the big services, whether it's the Navy or the Marine Corps.

Both of the programs we’re working on are all about mine countermeasures, and mines are really, really difficult, especially underwater mines. We've been we've been applying all of Nauticus’s broad technology portfolio to being able to search autonomously and being able to identify and neutralize threats in the water. I love that mission because anytime we can remove our service men and women from these situations, that's just the right thing to do.

IM: What’s next for Nauticus?

NR: What’s next is tough to talk about, because I can only talk about what’s already been published. I see Nauticus being the preeminent ocean robotics company. I want Nauticus to be an empire. It starts small but it grows — and it grows in many different ways, and we’re exploring all of those different ways to grow. We’re leading a technology renaissance in the marine space — and that happens only a few times in an industry.

Alabama-based renewable fuels company to move HQ to Houston

welcome to houston

An Alabama-based clean tech company is moving its headquarters to Houston.

Alléo Energy announced that it will move its headquarters from Bay Minette, Alabama, to Houston's Ion District. The company develops carbon-negative fuels and renewable commodities through its conversion technology that turns wood waste and cellulosic feedstocks into high-energy, high-yield syngas.

The news comes after Alléo announced the appointment of Benjamin Cowart as its new CEO. Cowart will succeed Alléo founder Simeon Chow, who will serve as president.

“Ben doesn’t need to be sold on carbon-negative fuels; he’s already building in this exact space, and he’s thrived through some of the hardest conditions the industry has faced,” Chow said in a news release. “He knows how to scale and he knows the capital markets that finance them; he turns the hurdles that stall other companies into momentum. Bringing a leader of his caliber in as CEO is a defining, energizing moment.”

Cowart previously founded Houston-based renewables Vertex Energy Inc. The company went public on the Nasdaq exchange in 2009 through a reverse merger. He served as chairman and CEO of the company, which was later taken private by a consortium led by BlackRock.

Cowart also founded EVH Corp., a venture platform focused on building in hydrogen, methanol, sustainable aviation fuel (SAF), and low-carbon marine fuels.

“I’ve spent my career turning advanced process technology into high-performing enterprises that deliver both economic and environmental returns in an industry defined by headwinds,” Cowart added in the release. “The winners in energy transition aren’t the ones with the best headline; they’re the ones that keep their economics intact when subsidies move, feedstock prices swing, and capital gets expensive. Alléo is well-built for that. I’ve rarely seen a technology company this well positioned for what the market is demanding. The science is proven; now it’s about disciplined execution, financing, and building more plants. This is the work I love most.”

Alléo plans to scale its proprietary conversion technology. The company commissioned the first phase of its Alabama facility in 2023, which produced renewable diesel made entirely from wood waste, which could be converted to SAF.

The company says that it has $50 million invested in initial research and development, and that additional facilities are in the planning stages.

J.J. Watt takes a run at energy sector with Base Power investment

power play

Since retiring from the NFL three years ago, Houston Texans legend J.J. Watt has been exploring a new field—investing.

In 2023, the former defensive end and current CBS Sports football analyst bought a stake in English soccer team Burnley FC. A year later, he invested in the PopUp Bagels chain.

This summer, Watt made what may be his highest-profile investment yet. He contributed to a $1 billion Series D round for Austin-based energy startup Base Power, which has an office in Houston. It’s Watts’ first investment in the energy sector.

“I like companies that solve real problems, and Base is lowering power bills, protecting families, and building the whole thing themselves right here in Texas,” Watt said in a company news release.

“What impressed me wasn’t just how fast they’ve grown,” he adds. “It’s that they’ve already saved Texans millions on their power bills and kept thousands of homes running when the lights went out. That’s why I invested.”

Base Power is building a distributed network of residential batteries that’s designed to strengthen the grid and lower electrical bills. The startup now powers more than 30,000 homes in Texas, including the Houston area, and recently expanded to Illinois.

Base Power’s $1 billion round lifted its valuation to $13 billion. Since being founded in 2023, the startup has raised more than $2.5 billion.

“JJ is a legend in this state, and he earned that as much for how he shows up off the field as for what he did on it,” says Zach Dell, co-founder and CEO of Base Power. "He spent a full day with us asking every hard question he could think of, and then he switched to Base himself. We’re glad to have him partnering with us.”

Zach Dell is the only son of Austin billionaire Michael Dell, chairman and CEO of Round Rock-based Dell Technologies. Michael Dell grew up in Bellaire.

Leading energy companies power Houston's presence on Fortune Global 500

world class

Nine Houston companies landed on the 2026 Fortune Global 500 list, which ranks the world's largest corporations by revenue for the 2025 fiscal year.

Houston's showing on the list was led by energy companies, with Spring’s ExxonMobil claiming the top local spot. Here’s what Houston-area companies made the list, and where they ranked:

  • No. 15 ExxonMobil
  • No. 36 Chevron
  • No. 61 Phillip 66
  • No. 159 Sysco
  • No. 243 ConocoPhillips
  • No. 292 Enterprise Products Partners
  • No. 343 Plains GP Holdings
  • No. 460 SLB
  • No. 481 Hewlett Packard Enterprise

After 12 years as No.1, Arkansas-based Walmart was replaced this year by Seattle-based Amazon in the top spot for 2026. Amazon achieved this by bringing in $700 billion in revenue in 2025, representing a 12 percent increase from the previous year.

"Across global business, we see again and again that the leaders who are winning are those who embrace change,” Alyson Shontell, Fortune's editor in chief and chief content officer, said in a news release. "Amazon has topped the Fortune Global 500, knocking Walmart off its pedestal. The company has continually reinvented itself across new businesses and bold bets—including a $200 billion capital commitment, largely to building its capacity for AI and cloud computing, in this year alone."

The U.S. has 141 companies on the 2026 Fortune Global 500 list, which is the most of any country. Companies in America generated $15.5 trillion in aggregate revenues, a 6 percent increase from the previous year.

The number of women CEOs at Fortune Global 500 companies reached a record of 34 top leaders, who represented 6.8 percent of CEOs of companies on the list.

Technology was the standout growth industry on this year’s list, with 38 companies earning revenues that grew 20 percent to about $4 trillion in 2025, with profits climbing 36 percent to $835 billion. The financial sector accounted for the largest share of companies on the list again, with 123 companies in that sector. The energy sector claimed the No. 2 industry spot with 77 companies making the list.

In June, the Fortune 500 list was released, and Texas led the United States with 57 Fortune 500 companies headquartered in the state, generating $2.8 trillion in combined revenue.
