<p>Wall Street's consensus is once again significantly lagging reality.</p>
<p>According to ZhuiFeng Trading Desk, the latest channel research from Morgan Stanley indicates that the mechanical hard drive (HDD) market is experiencing unprecedented strengthening in demand and pricing, with supply shortages expected to persist through calendar year 2028 (CY28).</p>
<p>Based on this, Morgan Stanley reiterates its Overweight Rating for Seagate (STX) and Western Digital (WDC), upgrading Seagate to its &#34;Top Pick&#34; over Western Digital. Morgan Stanley substantially raised Seagate's price target from $468 to $582 (potentially reaching $796 in a bull case scenario) and Western Digital's price target from $369 to $380 (potentially reaching $519 in a bull case scenario).</p>
<p>The market is currently severely underestimating the leverage of the HDD duopoly in AI and cloud data center spending. Morgan Stanley points out that these two stocks are currently trading at only 13-14 times their expected earnings per share (EPS) for calendar year 2027 (CY27). Morgan Stanley's CY27/28 EPS expectations are 25%-50% higher than the Wall Street consensus, and its gross margin expectations are 400-500 basis points higher (up to 700 basis points). With the accelerated cost reduction of high-capacity technologies like HAMR and pricing power exceeding expectations, Seagate and Western Digital are entering a golden window where gross margins are expected to reach the mid-to-high 50% range. Tactically, due to Seagate's current valuation discount and faster gross margin expansion, Morgan Stanley advises investors to switch their top pick to Seagate.</p>
<h2>A &#34;Stronger for Longer&#34; HDD Cycle: Supply-Demand Imbalance to Persist Until 2029</h2>
<p>Morgan Stanley's &#34;Stronger for Longer&#34; thesis remains not only intact but is strengthening. Research indicates that despite lower-than-expected single-digit (LSD-MSD%) growth in HDD unit shipments, the industry's exabyte (EB) shortage will still reach 200 EB in CY26 (10% of the market) and approach 250 EB in CY27.</p>

<p>This robust demand stems from the continued migration of cloud workloads and the widespread adoption of AI (which accelerates data generation).</p>
<p>Currently, HDDs still store approximately 80% of global cloud data. Under conservative assumptions (30% annual growth in cloud EB demand, eSSD capturing 2 percentage points of market share annually, and HDD suppliers refraining from adding any new greenfield capacity), Morgan Stanley projects that HDD supply and demand will not reach equilibrium until calendar year 2029 (CY29), which is 12 months later than previously anticipated.</p>

<h2>Dual Approach of Pricing Power and Cost Reduction: Gross Margins to Far Exceed Wall Street Expectations</h2>
<p>This is the most disruptive finding in Morgan Stanley's model: HDD suppliers are negotiating procurement orders for 2027/2028 with major hyperscale cloud customers at prices approaching $20/TB (or $0.02/GB). This price is more than 30% higher than Morgan Stanley's current benchmark assumption of $13-15/TB, and nearly 20% higher than its bull case pricing assumption.</p>
<p>On the cost side, as both suppliers transition to 40TB+ high-capacity drives starting in C2H26, the cost per EB will accelerate its decline over the next approximately six quarters. This &#34;ever-widening gap between price per GB and cost&#34; will drive Seagate and Western Digital's gross margins into the mid-to-high 50% range upon entering CY27. Morgan Stanley's latest gross margin forecasts are 400-500 basis points higher than the Wall Street consensus prior to CY27.</p>
<h2>Tactical Portfolio Adjustment: Why Switch the Top Pick from Western Digital to Seagate?</h2>
<p>While Morgan Stanley remains extremely optimistic about Western Digital, for the following four core reasons, Morgan Stanley has shifted its recent relative preference and &#34;Top Pick&#34; to Seagate:</p>
<ol>
<li>Catalyst Realization: The key catalysts for previously favoring Western Digital (narrowing the valuation gap with Seagate, leveraging SNDK share for deleveraging) were realized last quarter.</li>
<li>Valuation Discount: Seagate's current Price-to-Earnings (P/E) ratio is more than 1x lower than Western Digital's, while Morgan Stanley believes their valuations should be on par.</li>
<li>Faster Gross Margin Expansion: Bottom-up analysis of cost per TB indicates that Seagate should experience slightly faster gross margin expansion than Western Digital over the next 12 months (approximately 50 basis points faster), benefiting from a strong HAMR product portfolio transition.</li>
<li>Greater Upside in EPS and Price Target: Morgan Stanley anticipates greater relative upside in its 12-month forward EPS forecast and price target for Seagate. Additionally, Seagate is expected to repay its convertible bonds earlier, leading to less dilution of equity.</li>
</ol>
<h2>Core Assets for AI Data Centers That Are Severely Undervalued</h2>
<p>Morgan Stanley believes this is an elongated cycle (i.e., 2027 is not the peak), thus maintaining an 18x base target P/E for both Seagate and Western Digital.</p>
<p>Within the Russell 3000 index (companies with market capitalization greater than $5 billion), there are only about 20 companies projected to have an EPS annual growth rate exceeding 40% and gross margins greater than 45% by 2028, with Seagate and Western Digital among them. If we further filter for companies with free cash flow (FCF) margins exceeding 30% and returning over 75% of FCF to shareholders, only Seagate and Western Digital remain.</p>
<p>Compared to the memory market, the HDD market has a superior structure: only 3 players (the top two control 90% of the market), no Chinese competitors, an 80%+ exposure to data center revenue, and no new greenfield capacity. In 2026, the combined capital expenditure (Capex) for Seagate and Western Digital is approximately $1 billion, significantly lower than the over $90 billion spent by the top five global memory players.</p>
