Arm: right franchise, wrong point in the capex cycle

No argument with the business. The entry is the problem: the multiple already discounts two more years of a capex cycle that has historically run three.

Yuki Tanaka@yuki_tanaka

The economics turn on utilisation. Fixed cost per wafer is set at the capacity decision; every point of utilisation above the planning assumption drops through at close to full incremental margin, and every point below does the reverse. Utilisation is the tell. The company guided to a utilisation rate below its own historical planning assumption while holding the capex number flat, which sets up the operating leverage in the following year rather than this one. The position: no call. This is a name I want to own and not at this level, so there is nothing locked here and nothing for the record to grade. If the entry improves I will say so in a piece that does carry a call. What breaks this is a credible second source qualifying faster than expected. That is a two-year process historically, but a buyer willing to accept a specification compromise could compress it, and the pricing structure would go with it.

Useful framing. The utilisation assumption is where I disagree. How much does this depend on the macro cooperating?

Omri ShakedMAY 24

This changed my mind. The elasticity decay across the price actions is the tell. Does the thesis survive a soft guide next quarter?

Been long since the last one. The elasticity decay across the price actions is the tell. Does the thesis survive a soft guide next quarter?

Good piece. The mix argument is the part I had not considered properly. How are you thinking about the timing risk here?

Ines FerreiraMAY 26

Reading this against my own model. The utilisation assumption is where I disagree. Where does this break if rates back up another 50bp?

Noa BergmanMAY 25

Good piece. The margin bridge is doing more work here than is acknowledged. Is there a cleaner way to express this than the equity?

Yael BrennerMAY 25

I hold the other side of this. The channel data is what makes this hard to dismiss. Interested in what the kill switch looks like in practice.

Yuki TanakaAuthorMAY 25

That is the right objection. Rates hit the multiple rather than the earnings path. A 50bp move costs perhaps two turns and does not touch the thesis.

Yael BrennerMAY 24

Strong piece, one objection. The distinction between adequate reserves and the earnings path is well made. Would you underwrite this without the catalyst date?
