Toshiba Capacity Expansion Rumors Weigh on HDD Stocks; Wells Fargo Maintains Overweight on Seagate and Western Digital
nashnova research
Reports of Toshiba doubling HDD capacity dragged Seagate and Western Digital down 27% and 24% in October, but Wells Fargo calls the sell-off "clearly overdone" and maintains Overweight, seeing roughly 25% upside from here.
How steep is this sell-off?
Seagate closed Friday at $657.41, down 4.9%; Western Digital at $339.84, down 4.6%.
October losses stand at 27% and 24% respectively, with both stocks falling more than 14% over five straight sessions.
This means → the market is pricing Toshiba's expansion as imminent oversupply, wiping out nearly a third of market cap in one month.
Why does Wells Fargo say "overdone"?
Wells Fargo kept both stocks at Overweight but cut price targets sharply: Seagate from $1,180 to $865, Western Digital from $730 to $450.
Based on Thursday's close, those targets still imply roughly 26% and 25% upside.
In plain terms = Wells Fargo acknowledges the uncertainty from Toshiba's plans — hence the target cuts — but even after cutting, the stocks are still about a quarter below fair value.
Can Toshiba really capture 30% market share?
A Nikkei report claimed Toshiba would hold 30% of the HDD market by fiscal 2027. Wells Fargo pushed back directly: even with a capacity doubling, Toshiba could support low-to-mid share at best.
Wells Fargo also flagged a baseline error — Toshiba plans to double from fiscal 2025 levels, not fiscal 2026 as the market initially assumed.
This means → the gap between those two baselines is roughly 70–90 exabytes of storage capacity. The market overestimated the actual supply addition, so the sell-off was built on an inflated number.
What supports the medium-term case?
Wells Fargo projects gross margins for both companies approaching 70% by 2028, driven by continued price hikes, lower production costs, and tight industry supply.
Revenue forecasts: Western Digital rising from $15.8 billion in fiscal 2026 to $29.1 billion by 2028; Seagate from $15.3 billion to $28.2 billion — nearly doubling in two years.
This reflects an unchanged core thesis: AI-driven data storage demand is still expanding fast, and these two remain the most direct beneficiaries.
After a 27% drop, are holders still up for the year?
Despite the October rout, Seagate is still up 143% year-to-date and Western Digital up 99%.
In plain terms = this plunge looks more like a concentrated giveback of prior gains than a signal of deteriorating fundamentals.
The key verification point ahead is Toshiba's actual execution on its expansion — if delivery falls short, the current sell-off will look like an overreaction amplified by rumor.
