Western Digital (WDC.US) and Seagate Technology (STX.US) are both maintaining clear paths for profit growth, prompting Bank of America to raise the price targets for both companies' stocks. Analysts at Bank of America, led by Wamsi Mohan, stated in an investor report on Monday: "Hard disk drive (HDD) supply remains tight as manufacturers are not adding unit capacity, which we view as a structural change. Consequently, we continue to see demand outstripping supply and believe original equipment manufacturers (OEMs) still have room for further price increases." Bank of America increased Seagate's target price from $605 to $700 and raised Western Digital's target from $415 to $495.

In a bull-case scenario, Bank of America found that both companies could see substantial increases in total earnings per share (EPS) by 2028.

**Seagate Valuation Analysis** When evaluating Seagate, the analysts noted: "We estimate the current stock price of approximately $587 reflects a 2028 calendar year EPS of $29. This is based on an assumed 4% compound annual growth rate (CAGR) in nearline storage price per terabyte and a 48% operating margin for the 2028 calendar year, applying a price-to-earnings (P/E) ratio of 20x, which we believe aligns with Seagate's growth and margin profile. However, in a bull-case scenario, we see potential for its EPS to reach $45. This would occur if the price per TB reaches $20 by calendar year 2028, implying a three-year price CAGR of 16%, with an operating margin of 55%."

**Western Digital Valuation Analysis** Regarding Western Digital, Bank of America said: "We estimate the current stock price of around $400 reflects a 2028 calendar year EPS of approximately $20. This is based on a 0% CAGR in nearline storage price per terabyte and a 45% operating margin for the 2028 calendar year, also applying a P/E ratio of 20x, consistent with Western Digital's profile. But in a bull-case scenario, we believe its EPS potential could reach $33. This would require the price per TB to hit $20 by calendar year 2028, implying a three-year price CAGR of 12%, with an operating margin of 55%."

Business visibility is also improving as both companies secure long-term contracts with customers. Wamsi Mohan added: "The market remains an oligopoly, with only three OEMs supplying HDDs, and we see a low threat of new entrants." So far this year, the stock prices of both Seagate and Western Digital have more than doubled.

**The Resurgence of Hard Drive Veterans** At a time when solid-state drives (SSDs) are advancing rapidly, many had predicted the decline of hard disk drives (HDDs). However, Bank of America's significant target price increases for Seagate and Western Digital have served as a sharp wake-up call for investors who underestimated the industry. The HDD market is currently undergoing an unprecedented structural transformation: it is no longer synonymous with low cost but has become a highly profitable stronghold underpinned by data centers and the AI wave.

**Current Oligopoly** The mechanical hard drive market is currently in an oligopolistic state. After decades of fierce price wars and consolidation, the global HDD market has shrunk to just three major players: Seagate, Western Digital, and Toshiba. In terms of market share, Western Digital and Seagate form a duopoly, each holding approximately 40%-41%, while Toshiba holds about 19%. This highly concentrated structure creates a natural and formidable barrier to entry. For potential challengers, the capital expenditure and technological expertise required to develop high-capacity HDDs are prohibitively high. In today's market characterized by competition for existing demand, it is nearly impossible for any new player to enter. This stable triopoly allows the incumbent manufacturers to move beyond irrational, loss-leading competition and instead focus on achieving higher-quality profit levels.

The contraction of the consumer market and the explosion in demand from the data center sector are reshaping manufacturers' product strategies. In the revenue structures of Western Digital and Seagate, the proportion from consumer HDDs has plummeted from over 20% to less than 10%. Limited production capacity is being prioritized for higher-margin enterprise clients, effectively marginalizing consumer products. This structural shift is moving the market strategy from broad coverage to precise focus.

**Persistently Tight Supply** The "persistently tight supply" is not accidental but a strategic choice by manufacturers. In the past, drive makers increased capacity to capture market share, leading to price collapses. Now, analysts note that manufacturers are halting the addition of new unit capacity.

**Counter-Trend Price Increases** This marks a transition for the HDD industry from being driven by scale to being driven by profitability. With capacity essentially fixed and demand for mass storage from data centers and cloud platforms surging due to the AI wave, the market balance has rapidly shifted in favor of sellers. HDD pricing trends have shown a remarkable counter-cyclical rise during 2024-2025. In 2024, HDD shipments grew for the first time in a decade, with overall sales revenue surging 50% compared to 2023, and the average selling price returning to peak levels last seen in 1998. Entering the second half of 2025, Western Digital and Seagate successively announced across-the-board price hikes, leading to an average increase of about 50% for mainstream HDDs over four months, with some models seeing increases as high as 66%. Even though Seagate's capacity for 2026-2027 is fully booked, Western Digital's CEO explicitly stated a reluctance "to build capacity without foreseeable use." This deliberate supply limitation, combined with the shift of capacity from consumer to enterprise segments, has created a tight supply-demand balance, further driving up prices.

**Valuation Logic Reassessment** The mechanical hard drive market is undergoing a profound value reassessment. Within an absolute oligopoly, the demand for AI cold data storage has broken the deterministic view of HDDs as a sunset industry, shifting the dynamic from "volume growth and price decline" to "stable volume and rising prices." The production control strategies of the three giants and the strategic abandonment of the consumer market signal the industry's entry into a new phase of high-margin, high-precision operation. When Seagate's target price is set at $700 and Western Digital's is viewed favorably at $495, the market is essentially pricing in a high degree of certainty. In the outlook for calendar year 2028, the two giants' EPS could potentially reach $45 and $33, respectively. The fact that their stock prices have more than doubled this year is not seen as a bubble but rather a market repricing of HDD value. In an era where data is the "new oil," as the barrels carrying this resource, HDD giants are reaping the benefits of their oligopolistic position.
