Set forth below is a transcript of the live Yahoo Finance interview on August 19, 2026 between Samuel Reeves, Founder and Chief Executive Officer at Fort Robotics, Inc. (“FORT”) and Josh Lipton of Yahoo Finance on “Asking for a Trend” in which the proposed business combination between Newbury Street II Acquisition Corp and FORT is discussed.

Josh Lipton

Hello and welcome to Asking for a Trend. Well, FORT Robotics, a company aiming at advancing the safety of physical AI, is going public as it faces increasing demand amid a growing robotics industry. Founder and CEO Sam Reeves joined now to discuss. Sam, it is good to see you. Maybe start here, Sam. Just explain for us, broad strokes, what you all do? Because I was reading up on it, Sam, and it sounds like you know you’re you’re not building the robots. You’re building it sounds like the software and the hardware designed to make the robots safe. Is that a is that a simple but good way to think about it, Sam?

Samuel Reeves

Exactly right. We are a safety platform for physical AI and robotics. The big picture is that physical AI and robotics is going to change the world. There is a huge need for physical AI and robotics. There are more than 4 million safety incidents in the in the work in the American workplace every year. Every single physical worksite has a huge labor shortage. So there are a ton of tasks, a ton of work that’s just not getting done. So there’s a huge need. We have more than 600 customers that are that are addressing that need with new robots, but they’re all machines that are driven by AI. And if you’ve ever used like ChatGPT or Claude and and and thought like, hey, the the result that I’m getting there is, is not quite right. If you’ve ever experienced a hallucination in AI, you realize that AI makes mistakes. So if we’re going to have physical AI entering the world in a big way and changing the way that that physical work happens across the board, like we have to make sure that it’s safe. And so, so, so there are going to need to be guardrails that sit independent of the AI, right, in between the machine and the AI driver, and those guardrails are really tough to build. And so FORT gives gives our customers building blocks that they use to build those AI guardrails.

Josh Lipton

So give me a real world example, Sam. Like let’s say I’m standing next to a robot on a factory floor. Your tech does what?

Samuel Reeves

So, so we’re a governance device or a piece of software that sits inside a machine, and you program the rules. However, the rules are whatever the rules are for that robot. So, think about about a humanoid or a humanoid robot or an autonomous forklift or an AMR, the kind of machines that you have on the screen, so they’re working autonomously much of the time. But our device lets you, our device and our software lets you connect those machines to the outside world. So you might want to connect a humanoid to a door lock and access control system, or you might want to connect it to a safety sensor, or you might want to connect it to a human with a wireless emergency stop or a wireless remote control. So our governance device lets you build those kind of safety connections. And if if something happens, if somebody opens a door and comes into the robot’s area, or if a fire alarm goes off, or if a safety sensor senses that something has gone wrong, then we can stop the robot or slow down the robot or something like that. So, so it’s these things are supposed to operate autonomously most of the time, but if there are situations where the robot, the AI is trying to break the rules, or the rules need to change, then there has to be an independent device that can always intervene. So that’s that’s the system that we provide, and and then building with Ford, building with with with external building blocks from a specialist company, helps our customers get through development faster at lower cost. And then when their robots show up on work sites, usually with very large companies as customers, our our our customers can just sail right through the the the safety bag because they have FORT inside.

Josh Lipton

You know, one question I had, Sam, as we’re thinking through this, is you know, if a robot makes a mistake, or maybe a robot even causes an injury, Sam, who’s responsible for that? Like, is that the robot maker? Is it the AI company? Is it a company like yours? Is it all free? Where does responsibility ultimately fall? Do you think?

Samuel Reeves

Well, I think you’re you’re speaking to one of the defining questions of our time, which is how how we take these things that have a completely new risk profile, like these things. That that that’s why there’s an opportunity to for for it to exist is because these these machines are moving. They’re driven by AI. They’re not always working behind gages. They’re working around people and valuable property. They’re connected to the internet with all kinds of cybersecurity issues. So, like that that description is a completely new risk profile, and so that’s why there’s an opportunity to FORT for FORT to exist, right? But directly to your to your question, it depends on what happened. Like safety is a team sport. You know, there are component providers like us. There are robot robot OEMs like our customers. There are robot integrators that install them in the facilities. There. The end user facilities where, where that are actually operating the robot. So, if there is an incident, and we have a perfect safety record, so this does not happen with us. But if there is an incident, you really need to be able to just get back to the root cause, and see what happened. And so, so really, the answer, the short answer is it depends.

Josh Lipton

Sam, you’ve gone public. Why go public now, Sam, and why via SPAC, which you know have a complicated reputation?

Samuel Reeves

Well, I’ve been in robotics for 20 years. I’ve started several robotics companies. I’m a career robotics entrepreneur. I’ve got a long-standing belief that autonomous robotics are going to change life for humans and change it for the better, and that goes back to my original company that was doing landmine clearance robots originally with the DoD and then with the UN. And so, this long-standing belief that robots are going to benefit humans is now starting to really happen in a big way. So you see, our 600 plus customers now starting to scale, and so we have tremendous growth within our within our own numbers of customers and within revenue per customer, and we just have more demand than we can satisfy, and so we need a way of scaling up further. We’re already at significant scale. We need a way to scale further, and we felt the best way of doing that was by going public and gaining the tremendous fundraising capabilities that that being a public company has, and the tremendous visibility that being a public company has the SPAC is a is a technique for going public, and it’s it’s a it’s an efficient way to do it. It’s a quick way to do it. Quicker. It has not been overnight, but it was a quicker way to do it with known outcomes and known partners. Some of the executives of Newbury II, which we are merging into, have tremendous track record in this space. Tom Bushey helped build a company called Ondas, which has done very well in the drone space. Jen Vescio was an executive at Uber and saw many of the issues that we’re confronting. So it’s an opportunity for us to partner with these people as well. The the SPACS that came before this is a different story. I mean, like we we are one of the few SPACS in recent memory that has had significant revenue before going public. We’re extremely cost efficient, so we we don’t need a giant amount of capital just to survive. And so there’s a different kind of risk profile as a company for FORT coming into the SPAC, which you know, I think is is going to yield completely different results compared to some of the kind of horror stories that you hear from from years ago, which just don’t apply to this situation.

Josh Lipton

And finally, Sam, I see Mark Cuban, one of your investors. Now that’s interesting. Now, how did Mr. Cuban get involved? Now, I’m curious, what is what has Mark brought to the table beyond just capital.

Samuel Reeves

Well, Mark is a is an incredibly intelligent businessperson that seems to be able to see the future. So he’s been right so many times about the way the world is going that you know I think we feel fortunate to have him right about us, and and we we we we met him because he’d invested in some some robotics companies in in our in our space, and he along with people like Tiger Global and Prologis saw FORT as this horizontal opportunity where you know, from an investor’s perspective, even invest in for it and get exposure to the entire space with a very obvious kind of value proposition, which is safety, security, reliability, like the concept of trust. So, Mark has been a helpful advisor since early days, and we’re just honored to have him involved.

Josh Lipton

Sam. Great to have you on the show, today. Thanks for your time.

Samuel Reeves

My pleasure. Thank you.
