Lately, there have been rumors that Kioxia and Western Digital’s NAND flash and SSD divisions could merge. Western Digital has explored the potential of buying what was Toshiba Reminiscence (since renamed Kioxia) when it was spun out of Toshiba in 2018 to finance its troubled father or mother firm’s operations. could have been A three way partnership with Toshiba to acquire the very best circumstances for persevering with the NAND flash and SSD enterprise.

Latest hypothesis stems from a settlement with activist investor Elliott Administration in June 2022, when WDC stated it could contemplate separating its laborious disk drive and flash reminiscence companies. Since then, the corporate has thought of whether or not to launch a separate enterprise, promote its flash enterprise, or different choices that make sense. Latest rumors counsel {that a} resolution relating to the way forward for WDC’s storage enterprise can be made within the close to future.

Let’s take a look at the advantages and prices of WDC promoting its flash reminiscence enterprise to Kioxia. First, let’s take a look at the market shares of the key NAND suppliers. In response to Pattern Drive in Q3 2022, Samsung holds 31.4% of the market, adopted by Kioxia at 20.6%, SK hynix and Solidigm (Intel’s former NAND enterprise) at 18.5%, WDC at 12.6%, and Micron at 12.3% and different corporations 4.6%. Combining Kioxia together with his NAND enterprise in WDC ostensibly makes him the most important NAND maker with 39.1%, but it surely does not work out that means.

If Kioxia and WDC merge, some clients could shift a few of their enterprise from the brand new three way partnership to different distributors with the intention to scale back their reliance on that firm and help their opponents. That was actually the case when there have been huge mergers of HDD corporations within the 2010s. So Kioxia and WDC mixed will not be the market chief, a minimum of not for lengthy.

Additionally, let’s check out WDC’s flash and HDD revenues and income from the quarterly report back to see how the 2 WDC companies evaluate to one another. The chart under exhibits the corporate’s NAND flash and HDD quarterly earnings from Q1 2020 to Q3 2022. From a income standpoint, the 2 companies are considerably aligned with one another, with the HDD enterprise usually producing essentially the most income every quarter.

The next graph exhibits WDC’s NAND Flash and HDD enterprise gross margins. WDC’s NAND gross margins usually exceed these of its HDD enterprise. Gross margins ought to typically correlate with enterprise profitability. The slight decline within the HDD enterprise margin in Q2 2022 was as a result of firm’s vital changes in his HDD enterprise, and the decline within the firm’s legacy enterprise after a surge through the pandemic and overstocking in its nearline HDD enterprise. Observe that it is because of steady decline. After speaking about Kioxia’s financials over the previous couple of years, we’ll discuss once more about his NAND profitability in WDC.

The next graph exhibits gross sales and income in yen from Kioxia’s quarterly report. Whereas gross sales have typically elevated from Q1 2020 to Q3 2022, the corporate’s earnings are far more dynamic. Kioxia and WDC get their NAND flash from the identical fab in Japan. Why is the profitability of the 2 companies completely different?

Objective Analysis analyst Jim Handy wrote an article analyzing the profitability of WDC’s NAND business and Kioxia’s business in 2019.Jim factors out {that a} buying and selling association between WDC and Kioxia (then Toshiba Reminiscence) would enable WDC to account for as much as 50% of the three way partnership fab’s output. Nevertheless, he does not have to amass all 50% of the inventory, joint he solely must pay Kioxia for the merchandise he acquires from the enterprise’s fab. Constructing a NAND flash fab could be very costly. As soon as constructed, it is smart for the manufacturing facility to supply as many merchandise as doable with the intention to get a return on the capital value of the manufacturing facility.

This is a bonus for WDC when demand for flash reminiscence declines and costs drop. The corporate can restrict its potential losses by buying as a lot manufacturing from the joint fab as it could promote, however Kioxia should promote its personal shares and what his WDC cannot. This places further value strain on Kioxia. Because of this settlement, WDC NAND enterprise profitability tends to be extra steady than Kioxia.

Based mostly on this data, does it make sense for WDC to promote its NAND flash enterprise to Kioxia? Kioxia will undoubtedly profit, however WDC will lose vital income streams and income. . So it is superb that WDC does that. Whereas the 2 companies may very well be separated as separate corporations so long as the brand new NAND enterprise maintains product offers with Kioxia, it does not appear to make sense for WDC to promote its NAND enterprise to Kioxia.

Wanting on the fab association between Kioxia and WDC and the profitability historical past of each corporations’ NAND companies, the merger is much extra favorable for Kioxia than for WDC. This makes it laborious to consider that WDC will spin this enterprise out to Kioxia, however time will inform.
