$Sandisk(SNDK.US) and HBF thoughts:

An analyst question from the Sandisk earnings call: "High bandwidth flash, I'm wondering if you're seeing any price premium on that...versus conventional NAND."

Sandisk's response: "It's a little early to talk about pricing on some of those nodes just yet."

This answer has left me scratching my head...

HBF is Sandisk's near-term growth vector for entry into AI inference workloads. Since HBF will command higher ASPs than standard NAND flash, Sandisk's HBF economics need to be forecasted to gauge what this means for future earnings.

In turn, HBF pricing needs to be compared to HBM since every HBF order is an allocation decision made against HBM — same construction, same adv packaging capacity, same customer, same BOM line, same qualification cycle etc etc.

However, the part that left me confused is this.

It's usually the case in most industries that when you get these types of non-answers regarding new product pricing — it's a signal of a premium pricing model vs. incumbent companies and "competing" products. There are many examples you can Google separately.

So in simple terms, is this a signal that Sandisk's HBF is to be priced ~similarly to HBM?

This wouldn't make much sense since it's widely assumed that HBF is worse than HBM, by design. For example, HBF is lower latency and has slow and finite write endurance vs. unlimited for HBM.

Therefore, should HBF not be priced relatively lower than HBM to account for these shortcomings?

Ultimately, if Sandisk's HBF does get priced highly, what's to say that Sandisk's demand would remain sticky longer term?

These are just musings, but considering that the SK Hynix and Sandisk HBF specs were released earlier this week, I hope that Sandisk provides more clarity/clues in their Investor Day next week.
