The following is excerpted from the question-and-answer section of the transcript.

Question: Craig Irwin - Roth Capital Partners LLC - Analyst : Yes, I was on mute. I apologize for that. Thanks for taking my questions. So, Bob, can you maybe talk a little bit about your visibility with AI customers? I don't know if you can maybe just give us general color on backlog and backlog trends or orders and order indications and maybe even just the direct investment you're seeing in the different facilities that that you're selling into there as far as the customer commitments.

Question: Craig Irwin - Roth Capital Partners LLC - Analyst : Understood. You've explained the nature of the business in the past and it makes sense that it's not necessarily changing, just moving very well. So that makes sense. One area you guys have really impressed me over the last couple of years is on the execution bringing down OpEx, right, the $13 million in savings. Can you maybe frame out for us what the sublet savings could be from the under underutilized facilities? And I don't know if you can get more specific about which facilities, and whether or not these are sales or things where you're already leased and you can -- you're subleasing or if there's assets that can be sold.

Question: Craig Irwin - Roth Capital Partners LLC - Analyst : Okay, excellent. Excellent. Then to change subjects again, there's quite a lot of interest out there about new applications for silicon carbide. Some of these AI chip producers are apparently looking at a different substrates for future generations of chips. I know you guys get involved very early on, with different customer groups as far as development necessary for new processes. Are you seeing some new customers maybe come in or new opportunities come in that might broaden your participation away from TPS into substrates for some of the AI momentum we're seeing in the market?

Question: Craig Irwin - Roth Capital Partners LLC - Analyst : Yeah, I can clarify that for you. I'm sure you know, but you're probably limited as far as what you can say, but -- so I'll say it publicly. I know that the silicon carbide produced by Wolfspeed is used by EPC Power, a private company based in California, for the EPC power blocks sold by Vertiv. And those use 3.3 kV MOSFETs, which are much higher power than the MOSFETs using EVs. And that is the primary product going in on the leading edge data centers today. So I do know that DC is adopting silicon carbide for power. What I was curious about and really where things could get insanely interesting is if it's a substrate for the actual -- for the AI chips themselves and not just the power.

Question: Mark Miller - Benchmark Company LLC - Analyst : Just wanted to clarify. You indicated that the spread between equipment and reoccurring revenues was 60/40. Was that for both this Thermal Processing and the Semi Fab sales, or was it some differences there?

Question: Mark Miller - Benchmark Company LLC - Analyst : In terms of your backlog, is it that you said you've been focusing on higher margin products. What does it look like in terms of the margin profile of your existing backlog? Is it better than what you've been reporting recently?

Question: Mark Miller - Benchmark Company LLC - Analyst : Okay. You indicated that auto remains soft for you, but I was a little surprised by that because it's my understanding, at least, for EVs that auto sales in China are better this year than last year.

Question: Mark Miller - Benchmark Company LLC - Analyst : Thank you.

Question: George Marema - Pareto Ventures - Analyst : Hi, thanks for taking the call. Good to talk to you, Bob.

Question: George Marema - Pareto Ventures - Analyst : A couple of questions. Do you guys expect any effects from the ramp up of Blackwell versus Hopper and also the kind of the ramp up of these custom ASICs like TPUs, et cetera?

Question: George Marema - Pareto Ventures - Analyst : Okay. And then as you look out to '26 in terms of your focused R&D on innovative investments and new products, any update on any new products for '26 and new initiatives?

Question: George Marema - Pareto Ventures - Analyst : Okay. And then one last one. Has there been any change in the competitive landscape in thermal area?

Question: George Marema - Pareto Ventures - Analyst : Great. Thank you.
