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.

Fervo Energy officially files for initial public offering

going public

Fervo Energy has officially filed for IPO.

The Houston-based geothermal unicorn filed a registration statement on Form S-1 with the U.S. Securities and Exchange Commission on April 17 to list its Class A common stock on the Nasdaq exchange. Fervo intends to be listed under the ticker symbol "FRVO."

The number and price of the shares have not yet been determined, according to a news release from Fervo. J.P. Morgan, BofA Securities, RBC Capital Markets and Barclays are leading the offering.

The highly anticipated filing comes as Fervo readies its flagship Cape Station geothermal project to deliver its first power later this year

"Today, miles-long lines for gasoline have been replaced by lines for electricity. Tech companies compete for megawatts to claim AI market share. Manufacturers jockey for power to strengthen American industry. Utilities demand clean, firm electricity to stabilize the grid," Fervo CEO Tim Latimer shared in the filing. "Fervo is prepared to serve all of these customers. Not with complex, idiosyncratic projects but with a simplified, standardized product capable of delivering around-the-clock, carbon-free power using proven oil and gas technology."

Fervo has been preparing to file for IPO for months. Axios Pro first reported that the company "quietly" filed for an IPO in January and estimated it would be valued between $2 billion and $3 billion.

Fervo also closed $421 million in non-recourse debt financing for the first phase of Cape Station last month and raised a $462 million Series E in December. The company also announced the addition of four heavyweights to its board of directors last week, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE.

Fervo reported a net loss of $70.5 million for the 2025 fiscal year in the S-1 filing and a loss of $41.1 million in 2024.

Tracxn.com estimates that Fervo has raised $1.12 billion over 12 funding rounds. The company was founded in 2017 by Latimer and CTO Jack Norbeck.

Houston lawmaker may kill data center tax breaks due to $8B revenue loss

looking at the data

An influential Houston-area state senator is raising concerns about potentially billions of dollars in lost state revenue from tax breaks for Texas data centers—and is pondering legislation that would abolish the tax incentives.

Citing data from the state comptroller’s office, The Texas Tribune reports the state stands to lose nearly $8 billion in revenue from 2026 to 2030 due to sales tax and use tax exemptions for data centers. During the state’s 2025 fiscal year, which ended on Aug. 31, these tax exemptions caused Texas to lose a little over $1 billion, up from an earlier estimate of $130 million.

“These new numbers are extremely concerning, and I will say they’re unsustainable,” Republican state Sen. Joan Huffman, chairwoman of the state Senate Finance Committee, tells The Texas Tribune. “I plan to look at filing legislation to either repeal the exemption or take a very close look at it and see.”

Texas on track to be No. 1 data center market in U.S.

Scrutiny of the tax breaks comes amid an explosion of data center development in Texas, where data provider Aterio identifies nearly 1,000 centers that are operating, under construction or planned.

A report issued in January by Bloom Energy says the state is poised to become the No. 1 U.S. market for data centers within three years. By 2028, according to the report, Texas is projected to exceed 40 gigawatts of data center capacity—representing nearly 30 percent of total U.S. demand.

Among companies benefiting from the data center boom are:

  • Tech titans like Apple, Google, Meta Platforms, and Microsoft, which are spending billions of dollars to build data centers in Texas.
  • Spring-based ExxonMobil and Houston-based Chevron, two oil and energy giants that are developing natural gas plants to supply power for data centers.
  • Houston-based energy technology company Baker Hughes, which is collaborating with Google Cloud to develop AI-enabled power optimization and sustainability software for data centers.
  • DataBank, Data Foundry, Equinix, Digital Realty, Lumen Technologies, and IBM, all of which operate data centers in the Houston area.

The Texas Legislature will begin debating tax breaks for data centers in July, when Huffman’s Senate Finance Committee meets for an interim hearing before the 2027 legislative session, according to the Tribune.

Data center industry defends tax breaks

Leaders in the data center industry warn that watering down or halting the tax breaks could slow down or even end Texas’ ascent in the data center sector.

A 2025 report commissioned by the Data Center Coalition found that in 2024, data centers provided more than $1.6 billion in state tax revenue and almost $1.6 billion in local tax revenue in Texas. Over the next several years, according to the report, planned development of data centers in the Lone Star State could generate almost $3.8 billion in state tax revenue and more than $4.9 billion in local tax revenue.

In 2024, the Houston area had 8.1 million gross square feet of data centers, with the properties’ real estate investments sitting at $10 billion, according to the report. That year, data centers in the region produced a little over $700 million in state and local tax revenue. About 60 data centers operate in the Houston area.

Watchdog group warns of tax breaks’ danger to state budgets

On the other side of the debate over tax breaks for data centers, a report released last year by Good Jobs First, a nonprofit, nonpartisan watchdog group that tracks economic development incentives, decries the tax breaks as dangerous to state budgets.

“We know of no other form of state spending that is so out of control. Therefore, we recommend that states cancel their data center tax exemptions,” says Good Jobs research analyst Kasia Tarczynska, co-author of the report. “Shy of that, states should amend … legislation to cap how much any facility and company can avoid paying in taxes each year.”
