So basically all the nand manufacturers reduce capacity and raise prices, smells like a cartel is price fixing, time for an anti-competitive/consumer investigations.
Their sales dropped like a rock, so
obviously they had to cut back on production.
If you think about it for a minute, you can understand a little better. First, NAND has to go into SSDs. SSDs get made and sit in warehouses until they're sold. If SSD sales slow down, SSD production gets cut back. However, the SSD producers won't make more SSDs until retailers run low on SSD inventory and put in more orders, and those orders will be smaller. The SSD makers will have a certain amount of NAND in their inventories, and only order more when that runs low. If they're burning through their inventory of NAND slowly, it'll take them a while before they put in more orders, and those won't be as big. So, the sales slowdown gets
amplified as it reaches back to the NAND producer.
If you're a NAND maker, you have costs from R&D + running your production line. Your revenues come from selling chips. If your revenues drop near zero, you're going to lose tons of money, so you do what you can to cut costs. That means cutting back production + layoffs. Maybe even mothballing or selling factories, selling some assets, anything you can do just to stay in business. The steeper the downturn, the deeper the cuts. The deep cuts hurt your capacity, which it takes time to build back.
I'm not going to say NAND-makers have totally pure motives, but they have to do whatever it takes to stay in business. It's a business where adding capacity is capital-intensive and takes time, meaning it can't quickly scale up to meet spikes in demand.
Obviously, collusion is illegal and any serious allegations should be investigated. However, the current dynamic is not explainable
only by price-fixing. We just went through the biggest crash in NAND sales since the inception of SSDs. The industry has seen nothing like it, in its entire history!
