Analysts on hard drives: “Supply remains tight”

Bank of America analysts bumped up price targets for hard disk drive (HDD) industry leaders — and S&P 500 top stocks — Seagate Technology Holdings and Western Digital as surging AI data center demand for these low-cost, long-term data storage devices continues to ramp up. They wrote:

“We raise our calendar year hard disk drive exabyte shipment forecast to 1,602 exabytes (+28% y/y) from 1,575 exabytes (+26% y/y) and see room for further upside as demand continues to outpace supply. Despite double digit percentage increases in total capacity... from STX & WDC so far during C25, HDD industry supply remains tight.”

BofA boosted its price target for Seagate from $170 a share to $215, slightly above where the stock is trading on Monday. The analysts also increased their stock price target on Western Digital from $100 to $123, implying a roughly 20% premium to where its share were trading Monday afternoon shortly before 2 p.m. ET.

Besides being an influential market driver this year, demand for hard disk data storage also reflects the vast amounts of data that the boom in AI is expected to generate. (A single exabyte is the equivalent of 1 billion gigabytes.)

As a result, hard drive makers like Seagate and Western are focusing on the next generation of high-capacity data storage gizmos that pack more data bits. These devices are also more profitable than traditional disk drives, which has helped to boost the profitability of the industry, BofA analysts said.

“As HDD demand continues to outpace supply, STX & WDC have seen profitability metrics hit all-time highs,” they wrote.

Those profitability metrics could help explain why the stocks have suddenly caught the fancy of traders.

“We estimate that STX & WDC can get above 42-43% corp gross margin levels exiting [calendar year 2028],” they wrote. “But if pricing is stronger than expected or if manufacturing efficiencies lower COGS, we believe margins could go even higher. Key risks include pause in hyperscaler capex (low probability) and tariffs.”
