Hassane El-Khoury CNBC Interview Transcript

CNBC “Squawk on the Street” | June 26, 2026

David Faber:

Shares of onsemi, as you see, sliding today after the chipmaker unveiled its largest deal ever. It's an all-stock acquisition of Synaptics. It's got an equity value of about $6.2 billion, although worth less now given that decline in the stock price.

The deal is aimed at pushing beyond power chips and into what onsemi calls Physical AI.

Joining us now in a CNBC exclusive is onsemi President and CEO Hassane El-Khoury.

Good to have you.

Let's start off on that stock price. Hassane, it's not really our pressure, I don't think, because a lot of them are waiting to set this up to short the acquirer's stock, so what is your reaction to a 19% decline in your stock price after you announced an important deal?

Hassane El-Khoury:

Look, to be honest with you, for me, every decision we've made, every decision we make, including this one, has long-term strategic value for shareholders.

So I don't really react to reactions. We more respond to these.

So let me put the deal in perspective because it's important to understand the strategic value of it with where the company is today as far as onsemi.

You know, over the last few years, we have both organically and inorganically invested in differentiated technologies. We have established ourselves as a key leading player in power and sensing, both in automotive, industrial, and AI data center.

That thesis, that strategy remains intact.

What this deal provides is a TAM expansion, $30 billion incremental market expansion, in a strategic, forward-looking view of where the market beyond the AI data center into the physical AI.

That is the strategic value of it, complementary to everything we have done on a very strong foundation both market, strategic, and financial that we've established at onsemi.

David Faber:

Right.

All right. So you're calling this a move from being a component supplier to an intelligent systems company.

So what do you sell after the deal is completed that you aren't selling now?

Hassane El-Khoury:

Sure. When you think about an intelligent system, we define it as a complete build of materials that the customer will use.

Today, we are the primary as far as power, sensing. We've added control with our TREO platform.

At the center of every system is a compute platform.

And in the era of AI, that compute platform, that has historically has been referred to as an MCU, or microcontroller, is pushing into an AI-centric compute platform.

Synaptics already developed and delivers in the market that center compute, which is an AI-first compute.

That, in addition to all of the things we as onsemi provide to that system, provide that complementarity to create those intelligent systems in our existing end markets, and it opens up new end markets that Synaptics brings with them.

David Faber:

All right. So let's talk a bit about that because I think our viewers, many of us, are still struggling to fully understand physical AI.

I sat down with Jeff Bezos. He's got a startup called Prometheus, a lot about physical AI as well, sort of bringing AI to the physical world and obviously creating efficiencies.

What are you talking about in terms of end markets? What are you talking about that conceivably will be done as a result of this deal that you couldn't, and/or your customers couldn't, do previously?

Hassane El-Khoury:

Absolutely.

So let's talk about AI in two buckets.

The AI that we all talk about today is a data center-driven AI. That is a very strong business for us at onsemi.

We talked about ‘26 doubling from last year. That remains a strong business and a very growth business.

Beyond the walls of the data center, today all of us, you, me, and everybody else, interfaces with AI through a prompt. Whether it's coding prompt, whether it's research prompt, whatever it is, it's a prompt through the PC.

The next step of the AI evolution is that physical AI.

Think about it this way. A car with autonomous driving is in the physical AI realm, which is an AI on wheels. That is a physical AI market.

An industrial robot, or an industrial energy storage system, which we are also strong at on onsemi, will have analytics at the edge, not cloud, in order to better perform the energy storage system function.

That is in physical AI. That's complementary to what we do. That is AI also.

Humanoids, or robots, robots whether it's factory automation or humanoids, which is a forward-looking growth market in general, that is, I would say, AI on legs or AI on wheels.

That is in the physical AI realm.

All of these markets that we talk about as growth as an industry, or more and more content as an industry, those are all within physical AI.

David Faber:

All right. Let's talk more about the deal itself.

You're talking about $200 million in synergies. I think 85 to 90% your CFO said on the call will come in terms of OpEx, perhaps mostly SG&A.

So is that just overhead and headcount? Is there anything coming from product integration here that you would call a synergy?

Hassane El-Khoury:

The product integration, the product overall, we've talked about the full complementarity of the product.

There is no overlap in the product, which is why this deal is very exciting from an R&D and a product perspective.

Of course, with like any other deal where two public companies come together, there's the overhead, there's the public company cost, and so on and so forth. That's where the SG&A comes in.

We have a very broad sales network. We have a very broad distribution network.

We're going to bring that network to bear to get the top-line synergies, which we haven't sized, but of course they exist.

And then the rest of it is efficiencies we'll get from combining two public companies.

David Faber:

Are you still seeing the same demand from the data center?

You and I talked only a couple of months back, in early May at Milken, but there is, let's call it, growing concern. It may even be reflected in what you're seeing today in your stock price, which might otherwise have been down even without the deal.

Are you still seeing the same amount of demand? Worried about data center delays, for example, or anything related to that?

Hassane El-Khoury:

I see none of that.

That's why I started the call with the foundation that we have built is strong. We will continue to deliver on that.

We have no hesitation about our core business. That remains strong.

Actually, we see acceleration from our side because of the 800-volt transition.

I've always said the AI data center business is coming into the onsemi realm.

That is happening.

It's happening as early as '27, and that will be exactly where we at onsemi play a very strong role, which is the 800-volt conversion.

To remind everybody, we've been doing 800 volts in automotive for the last five years.

So putting that into the AI data center is really the most natural strategic thing for us to do, and that will continue moving forward.

David Faber:

Right.

Finally, just a final little deal question here as well.

You were asked, I think by the JPMorgan analyst on the call, about the Broadcom wireless connectivity license that you have.

Is there any risk that some of the connectivity that Synaptics has, the IP won't be allowed to transfer to you guys?

Hassane El-Khoury:

We are a complementary technology. We're very familiar with the connectivity.

Synaptics has done a lot of strides in developing that connectivity also, but we don't see that as a risk to the transaction.

David Faber:

All right.

And you've got to get China approval, so it could take a while, right?

Hassane El-Khoury:

Standard regulatory approval.

Obviously, the complementary nature of the products and, of course, our support of customers worldwide at a global footprint, we are expecting a normal regulatory process.

But we are expecting to close in the shorter term, in mid-2027, which puts it in a very favorable timeline.

David Faber:

All right. We'll be checking in between now and then as well.

Hassane, always appreciate it.

Thank you.

Hassane El-Khoury:

Absolutely. Thank you.
