WDC — Q1 FY2027 Financial Report Analysis

Overview

Western Digital (WD) sold $4.38 billion of hard drives in the first quarter of fiscal 2027, the 13 weeks ended October 2, 2026. That is 55% more than a year earlier, and the year-ago quarter had 14 weeks. Cloud drives made up 88% of revenue, and WD earned more on them in two ways at once: it shipped "more than 20%" more storage capacity (measured in exabytes; one exabyte is a billion gigabytes) and got "approximately 25%" more for each exabyte. Because the extra price costs WD almost nothing to deliver, gross margin rose 14.3 points to 57.8%. Gross margin is the share of sales left after the cost of making the drives. Operating income was 2.6 times last year's. Net income rose a smaller 51% to $1.78 billion, and diluted EPS rose 51% to $4.63. Both are held down by a one-time $611 million gain in last year's quarter. Without that gain, profit roughly tripled.

The numbers

Money is in millions of US dollars except per-share figures. This quarter had 13 weeks; the year-ago quarter had 14.

Compared with the previous quarter (Q4 FY2026, also 13 weeks), revenue rose 17% from $3,747M and GAAP gross margin rose from 54.1% to 57.8%.

Where the growth came from

Cloud (88% of revenue, +54%). This is drives sold to hyperscale data centers and enterprises. Per the 10-Q, exabytes shipped rose more than 20% "driven by strong demand for our high-capacity products," which the company ties to cloud expansion and "the increasing storage demands from AI." Price per exabyte rose about 25% "due to an improved pricing environment." Drive makers normally have to cut the price per unit of capacity with each new generation. A 25% rise in price per exabyte is the opposite, and it explains most of the margin jump.

Client (7%, +119%). These are drives for PCs and notebooks. Exabytes rose about 15% and price per exabyte rose about 90%. The filing attributes the price rise to "a shift in product mix to higher capacity drives and an improved pricing environment."

Consumer (5%, +19%). These are external retail drives, and this is the one place where higher prices cost WD volume. Price per exabyte rose about 70%, but exabytes shipped fell about 30%. The 10-Q blames "general softness in demand... as a result of the increased pricing levels." The segment is too small to move the totals. Still, it shows that price-sensitive buyers have started buying less.

Costs stayed flat. R&D fell $11M to $283M because of lower compensation costs. SG&A (selling, general and administrative costs) rose $24M to $162M. Revenue grew by $1.56 billion, but cost of revenue rose only $256 million. Nearly all of the extra revenue reached operating profit, which is why operating margin reached 46.7%.

Fewer large customers by share. The top 10 customers made up 64% of revenue, down from 73%. Two customers were 14% and 13%, compared with four customers at 12–16% a year ago. One caution: WD changed how it counts this. Sales made through distributors or contract manufacturers are now credited to the end customer, and the prior year was restated the same way. Part of the change may come from that, not from new customers.

What the headline numbers hide

• Net income growth is understated. Last year's quarter included a $611M gain on WD's retained Sandisk shares, and that gain was not taxed. Without it, prior-year net income was about $571M, so this quarter's $1,779M is roughly 3.1 times as much. WD's non-GAAP diluted net income ($655M to $1,779M, +172%) tells the same story.
• One fewer week makes growth look smaller. Fiscal 2026 had 53 weeks, and the extra week fell in last year's Q1. Comparing 13 weeks with 14 makes the 55% revenue growth look lower than it was. The comparison next quarter is 13 weeks against 13.
• GAAP and adjusted EPS match by coincidence. Non-GAAP operating income is $107M higher than GAAP. The difference is mainly $79M of stock-based compensation and $27M of cash severance; the adjusted figure leaves both out. But the adjusted figure also applies a 17% tax rate, while GAAP tax was only 13%, and the higher tax cancels out the add-backs. The low GAAP rate came from a $98M "excess windfall tax benefit." That is a tax deduction WD gets when employee stock awards vest at a value above their grant price, and the share price was around $460–$530 when WD was buying back stock this quarter. The benefit depends on the share price and will not recur reliably. Without it, GAAP net income would have been about $100M lower.
• The share count went up despite $1 billion of buybacks. WD bought back 2.0 million shares for $1.00 billion. In the same quarter it issued about 14 million shares (4.7M and 9.3M) to settle the "conversion premium" on its convertible notes. These are bonds holders can swap for stock, and with the stock far above the $37.70 conversion price, that premium had grown to billions of dollars. Shares outstanding rose from 361M to 374M, and diluted weighted shares rose from 376M to 384M. So none of the EPS growth came from a smaller share count. All of it came from the business.
• Cash conversion was solid, with working capital growing. Operating cash flow was $1,604M, or 90% of net income. Inventories rose $269M "as we ramped production in response to growing demand." Receivables rose $206M. On the balance sheet, receivables grew 10% and inventory 18% over the quarter, while revenue grew 17% from Q4. That is roughly in line with sales, not a buildup of unsold stock.
• Cash went out faster than it came in. Free cash flow was $1,377M, but financing uses totaled $1,644M. That included buybacks ($1,001M), $570M of cash to settle convertible notes, $317M of taxes paid on employees' vested stock, and $56M of dividends. WD covered the gap with cash on hand and a net $300M from its revolving credit facility, which now stands at $650M and matures in January 2027. Cash fell from $1,579M to $1,314M. Total debt fell from $1,060M to $791M, so cash still exceeds debt, but WD is borrowing short-term to fund returns to shareholders.
• Restructuring continues. Business realignment charges were $43M ($27M cash severance plus $16M in stock awards). The 10-Q expects about $74M more in employee termination costs over the rest of fiscal 2027.
• Capital spending is stepping up. Capex was $227M (5.2% of revenue), compared with $73M a year ago. Management expects capex to run "modestly above" its long-run 4%–6%-of-revenue range for the next two years, spent on "heads and media technology and factory automation."

Takeaway: This quarter's growth came mostly from pricing. Cloud price per exabyte rose about 25% while costs barely moved, so gross margin rose 14 points and operating income rose 2.6x. The Q2 guidance assumes another step up, to a 60%–61% gross margin. The thing to watch is how long WD keeps that pricing power. The Consumer segment, where volume fell 30% after price increases, is the first sign of buyers pushing back.

Did last time's read hold up?

Our fiscal 2026 annual report flagged three things to watch, and this quarter beat or met each of them.

• Cloud exabyte growth against the longer year-ago quarter. It held. Exabytes rose more than 20% even with one fewer week.
• Whether gross margin reached the guided 55%–56% (non-GAAP). It came in at 58.1%. Revenue of $4.38B also beat the $4.0B–$4.2B range, and non-GAAP EPS of $4.64 beat the $3.85–$4.15 range.
• How many shares the note conversions add. About 14 million shares were issued this quarter. Diluted weighted shares were 384M, below the ~388M WD had guided, because buybacks offset part of the dilution. Only $141M of notes remain. WD has called them for redemption on November 16, 2026 and expects nearly all holders to convert first, so a little more dilution is still to come.

We also noted the risk that WD's long-term contracts, which set "predetermined or formula-based prices," could cap further price increases. They did not do that this quarter: Cloud price per exabyte still rose about 25%.

Outlook

Management's guidance for Q2 FY2027 (the 13 weeks ending around early January 2027) is on a non-GAAP basis, from the October 22 earnings release:

At the midpoint, revenue would be about 16% above this quarter's $4.38B, gross margin would rise about another 2.4 points, and EPS would rise 25%. The board also raised the quarterly dividend 17%, to $0.175 a share. Management says customers are signing contracts earlier and for longer terms because high-capacity drives take longer to make. That supports the near-term outlook.

Our read: Results beat guidance this quarter, and the next quarter's guidance is higher again. The filings show no sign yet that the upcycle is slowing. Three things are worth tracking in the Q2 report. First, whether Cloud price per exabyte keeps rising or starts to level off, since pricing did most of the work this quarter. Second, whether falling Consumer volumes spread to Client, where price per exabyte has now risen about 90%. Third, how WD refinances the $650M revolving credit facility before it matures in January 2027 while buybacks keep running ahead of free cash flow. Revenue still depends heavily on a few large cloud buyers, so a pause in spending by any one of them would show up quickly.
