To all on thread,

Here's a real story about Cree lighting.

Our Chevrolet dealership installed new Cree LED lighting back several years ago. After about a year,we started having failures of the fixtures. Three years later every fixture had failed and needed to be replaced. The sealer being used had allowed moisture to enter the fixture causing corrosion.

Two years later our Chrysler store upgraded with a newer model also made by Cree - this time very durable and unbelievably bright at night. Huge electrical savings at both stores.

Cree eventually warranteed all of the original fixtures (over $100,000). A very solid company that stood behind their initial designs, and eventually GOT IT RIGHT.

So you can now understand why lighting fixtures had margin problems (warranty issues).

Cree's numbers look very good considering the head winds.

Interesting line from the CEO on the con call...…

"I don't think we're going to give out specific details on the CapEx spend. Obviously, most of the CapEx -- in fact, nearly all of the CapEx is heading into the Wolfspeed expansion as you had noted"

I also thought that this was interesting. I thought that the question would be shot down but they answered in such a way to clearly communicate that shifting capacity from LED's to Wolfspeed is a possibility.

They also talked about trying to double their capacity faster than their previous 24 month timeline. The only thing missing from the call was an increased target for Wolfspeed revenue in 2022 (think it is $850m right now)....but it makes sense to under promise and over deliver.

Hey thanks. Just a follow-up. Gregg, just with respect to the tightness in the markets, and I'm sure you've looked at this. But could you provide any insight in terms of the fungibility associated with the LED business and the Wolfspeed business with respect to lead-time and as well as maybe some greater clarity on switch out costs associated with that?


Gregg Lowe


Sure. From a material base wafer or silicon carbide wafer perspective, the fungibility is extremely high and extremely fast, so we can move crystal growth capability from one to the other pretty, pretty readily and be up in production and running and turning that into revenue very, very quickly. So, that's highly fungible and relatively fast.


From a wafer production standpoint, that is also highly fungible. Between the two, I don't -- I can't give you the exact percentage, but a very, very high percentage of these tools are going to be very similar.


There, of course, you have to go through a process of qualifying a product in a different fab and so forth, so it takes a little bit longer. We were able to qualify very recently some power products in another line that was running in the LED fab. So, we're seeing a little bit of relief right there. But yes, obviously, that takes a lot more work. And you got to get qualification and you got to get customer approval, all these sort of things. So, in both instances, the capacity is highly fungible, in one, it ramps a lot faster.


Jonathan Dorsheimer


Got it. So just when we look at whether it's three, four or five, whatever the demand increase on that logarithmic curve is based on EVs, the $220 million plus, you could essentially shutter the LED to half that capacity, keep that at 100% utilization and shift that over within a quarter or two, correct?


Gregg Lowe


I don't know about the quarter or two from customer acceptance and so forth, but yes, we can shift that over. Timing guys really need to think through, but it's probably a little longer than that.

Gregg's done a fabulous job so far...….what a big difference from the Chuckster!

Some interesting comments from II-IV about their SiC business.

seekingalpha.com

Our silicon carbide substrates business across all end markets accounted for 6% of revenue.


snip....................



I think we may have mentioned one quarter or two ago that the crossover, the place where now our silicon carbide substrates for power electronics are actually more than 50% of the revenue generation for this product-line. And over time, given the size of the electric vehicle infrastructure and the sheer value proposition of silicon carbide for inverters and for industrial motor drives, for a power factor correction and the like, it is going to be the biggest part of the market.


The good news is that GaN on silicon carbide, the market itself is growing and so even our semi-insulating RF substrate business is also growing. But for sure we see the power electronics basically going to stay and surpass it. 6% of the revenues in the quarter were for the whole of the product portfolio and more than half of our revenues were for their power electronics. Is that fair?

Keith, can you talk about the Silicon Carbide contribution in Q4 and also how you expect that to ramp throughout 2019, and a similar follow-up on EVs in terms of what you expect year-over-year? Thanks.


Keith Jackson


So Silicon Carbide itself is still young and ramping for us. We're talking as I mentioned in the last call tens of millions last year, ramping to hundreds of millions in the next couple of years. So, it's still pretty early in that. We did see our first usage in EV automobiles for Silicon Carbide in both third and fourth quarters. I'm expecting EV to ramp quite nicely with all of our related products this year. I don't have an exact growth number but it's certainly going to be very high-double-digit numbers.
