FORT Robotics agreed on August 18 to go public through a merger with Newbury Street II Acquisition Corp (NASDAQ: NTWO), in a deal carrying a pro-forma enterprise value of about $557 million against a pre-money equity value of $500 million. The Philadelphia company expects to trade on the Nasdaq under the symbol FROB after the deal closes, which management is targeting for the fourth quarter of 2026.

‍

Mark Cuban is in. So are Tiger Global and Prologis Ventures.

‍

That's the headline, and it's the least useful thing about the deal.

‍

FORT was founded in 2018, and it doesn't build robots. It builds the wireless emergency stops, the safety controllers and the software layer that let somebody else's autonomous machine operate near a human being. More than 600 customers use it, including Google DeepMind, Zoox, DoorDash, Ocado and Textron.

‍

What you're actually buying

‍

You're not picking a winner among robot manufacturers. You're betting that every one of them, whoever comes out on top, has to get a machine signed off before it goes near a warehouse floor or a public road.

‍

That's a different kind of exposure to the same theme. FORT gets paid on deployments regardless of whose logo sits on the chassis, and its platform carries an industrial functional-safety certification. That's a credential that takes years to earn, and it makes customers slow to switch once they've built around it.

‍

In May the company bought Mapless AI, which added remote human-in-the-loop control. A person can now take over a machine from a distance when the software gets confused, and that widens what FORT can charge for.

‍

The growth math behind the valuation

‍

Worth noting: revenue grew 62% in 2025 while operating expenses grew just 19%, which tells you the cost base isn't scaling in step with the top line. Gross margin came in at 66%.

‍

Here's how the money works, assuming no shareholder redemptions:

‍

* $201 million in gross proceeds at closing

* $182 million in net cash to the balance sheet

* $31 million committed by Cuban, Tiger Global and Prologis Ventures

* Existing holders rolling all their equity for roughly 67% of the company

‍

Insiders keeping two-thirds of the business and putting fresh money in alongside it is a reasonable signal about how they read the price.

‍

Where this could break

‍

To be sure, none of those percentages come with a dollar figure attached. FORT disclosed a growth rate and a margin, but not the revenue base they apply to, and 62% on a small number is a very different business from 62% on a large one. The S-4 registration statement still has to go to the SEC with audited financials in it. Until that lands, you are valuing a company on ratios.

‍

Make no mistake: the redemption risk is real. Every one of those cash figures assumes Newbury Street II shareholders stay put instead of cashing out at closing, and that assumption has fallen apart plenty of times before.

‍

Then there's timing. FORT's revenue depends on robot deployments actually happening at scale, so if the physical AI buildout slips a couple of years, the safety layer slips right along with it.

‍

If you're watching this one, the number to wait for is the first real revenue disclosure in the S-4. Everything else in the announcement is a rate of change without a starting point.
