Commission File No.: 001-42142

Date: July 28, 2026

On July 28, 2026, O'Shea Jackson (“Ice Cube”), an executive officer of BIG3 HoldCo LLC, which is a party to the previously disclosed Business Combination Agreement, dated as of June 12, 2026, with Graf Global Corp. and Halfcourt Holdco, Inc., among other parties, participated in an interview with FOX Business’ Making Money. The transcript of said meeting can be found below:

Charles Payne (00:01):

All right folks, my next guest came onto the scene with the rap group NWA. Then he appeared in over 40 movies, including the Friday movies, Barbershop series, and Are We There Yet? And of course, Ride Along. And now he's making big moves in the sports world, which by the way, Apollo says is a $2.5 trillion opportunity. Joining me now, BIG3 co-founder and CEO, Ice Cube.

Ice Cube (00:26):

How you doing?

Charles Payne (00:26):

I'm good, my man. I'm good. We're going to discuss the BIG3 in a moment, but I got to tell you, I've been following your career from day one. And when I research you, one of the things that I find so important is you come from a strong family foundation. And we talk about success all the time on this show, on this network. Why is that so important? Because you went through a lot of challenges and I know that might have been the key reason you overcame them.

Ice Cube (00:52):

Oh yeah, definitely family support is big because you really need people to lean on when times get tough, especially in a business like entertainment. When I was young, I was a teenager when I got into it, and you're not as sophisticated and don't know the ins and outs that you're facing. So you need a strong family to help you through that without suffering the things that entertainment has lined up for young stars.

Charles Payne (01:28):

I got to tell you, so I've watched the BIG3 since inception and I'm a little jealous because I grew up playing 3-on-3 and I'm saying, "Golly, why didn't I think of that?" Everyone's playing it. You have the foresight to say this could be a league and not just any league, but a big league. Walk us through just your moment of saying, "This could be something huge and I'm going to take care of it."

Ice Cube (01:53):

Well, I grew up playing 3-on-3, loving 3-on-3, even more than five on five because you get more action. And I always wonder why wasn't it professionalized? Why wasn't it kind of grown to the level of the NBA? And I looked around and nobody was doing it. And it was kind of laying there dormant. And we were like, "Yo, let's professionalize it and get the best in the world to play." Basketball is one sport that plays all over the world. Like boxing or like soccer, basketball's played everywhere and people will be surprised that there's more three-on-three played in the world than five-on-five. And so it was just sitting there ready.

Charles Payne (02:42):

So you go on public, your symbol's going to be T-O-N-T, 3-on-3. It's a big move. Congratulations. The transaction valued at almost 300 million. But why go public? Why be publicly traded?

Ice Cube (02:59):

The time is right. We've grown the league to have millions of fans and we're in the age of interaction. With sports is the last thing you can really interact with. And in the world of AI, sports is the last frontier when it comes to having those experiences. Maybe concerts, but sports is more global. And so it's right there. It's like a situation where people who love the league, why shouldn't they grow with it? Why should just the billionaires have all the fun, so to speak? It's really about, I want the public to love this league, to grow with this league, and they should be a part of the action.

Charles Payne (03:50):

Yeah. And again, they can invest in it, which is something that's a theme in this show. By the way, amazing talent from top to bottom, the commissioner, the coaches, everything. Before I let you go, the question everyone keeps asking me when I said Ice Cube's going to be in the shows. When's the next Friday movie coming out, my man?

Ice Cube (04:09):

Soon. We actually just turned the script in. We got a thumbs up from New Line, Warner Brothers, which is great. And now we're on our way to. We got to pay some people and we going to make a movie. It's going to be

Charles Payne (04:25):

Great. Ice Cube, you've done it all. Congratulations. We'll keep watching.

Ice Cube (04:30):

No doubt.

Charles Payne (04:31):

All right.

Ice Cube (04:32):

BIG3.

Charles Payne (04:33):

BIG3.
