On September 16, 2024, Joe Kiani, Chief Executive Officer of Masimo Corporation ("Masimo" or the "Company"), participated in a conversation with Caroline Hyde on "Bloomberg Technology". The following is a transcript of the conversation, portions of which may be deemed proxy soliciting materials. While effort has been made to provide an accurate transcription, there may be typographical mistakes, inaudible statements, errors, omissions or inaccuracies in the transcript.

Caroline Hyde: Coming out of the weekend, it really was the health side of the equation that stole the show. But as Apple, of course, sinks this morning following last week's product launch event, the company still hasn't resolved their legal fight with Masimo Corp. There's a blood oxygen detection, of course, that that company offers, which prompted a US ban on Apple Watches featuring the technology. Now, Masimo has partnered with Google and Qualcomm to develop a reference platform to help bring more smartwatches to market with their biosensing capabilities. Joining us now is Joe Kiani, the CEO of the Company. And what is this about? You have impressive health features, but Apple Watch, we just heard the new unveiling. They're getting sleep apnea and the like. How do you compete there, Joe?

Joe Kiani: Well, we compete based on good science. We have continuous accurate SpO2, pulse rate. We can even measure hydration, pulse rate variability, and nobody else has that. In fact, I don't understand how you can do sleep apnea without SpO2. I know clinically it's not done. So it will be interesting to see if Apple's promising things they can't deliver again, like they did with their SpO2, or if they really have figured out how to do it without SpO2. Time will tell.

Caroline Hyde: So you're offering this platform with Qualcomm. You're helping Google offer more smartwatches, more health features. It feels as though that, Joe, look, if you don't think that Apple can deliver what it promises, does that mean more court action? Where does your fight currently stand with Apple and its smartwatch?

Joe Kiani: Well, we, as you know, enjoined Apple from selling SpO2 in the US. There's a trade secret case that's going to be reheard, and if we win that, then we'll have a broad injunction against them on photoplethysmography. So they can't even do pulse rate and arrhythmia detection. And then if we win our patent case, which is about how you do photoplethysmography with very low battery consumption, then that will be an even wider injunction. So potentially our injunction could go worldwide and much broader. However, what's really cool is this partnership with Google, which I'd love to tell you more about. We're excited about it. Every Android user now can have a real, scientifically based, continuous, accurate wearable with this reference design we're creating with them. And I think in the next couple of years, you're going to see a slow--slew of products, from luxury products to smart watches from the typical Android world that will be an incredible offering for our mutual customers.

Caroline Hyde: I hate to say it, Joe, because we've only got a minute, so I ask for it to be brief, but you've got some fascinating things happening. You've got a proxy battle going on at the moment. They want to see more governance, want to have more board oversight. How do you fight Politan?

Joe Kiani: Well, you saw that Politan was found to have lied to our shareholders. The court--a federal judge found multiple lies, held them in contempt. So you've got someone who has no integrity that talks about governance. Yet you have us, who've done everything right--morally right, not just even legally. And we've made all this progress from bringing the business through COVID and now this incredible Google partnership. I think this should be 91% to 9%. Only person voting for him should be him.

Caroline Hyde: Joe, we wish we could have more information from you. Maybe we'll get you back after the vote come September 19. We thank you, Joe Kiani, CEO of Masimo. This is Bloomberg Technology.
