Seagate makes hard disk drives, the spinning magnetic storage devices that hold most of the world's data. Cloud companies, corporate data centers, security camera networks, and everyday PC users all buy Seagate drives. The company earns money each time a drive ships, and because cloud providers keep building more data centers, Seagate has been pushing drives with ever-higher storage capacities to serve them. It also sells solid state drives, storage systems, and a cloud-based data transfer service called Lyve. The diagram below traces where the money goes.

Five years of numbers tell a clear story: a good peak, a painful crash, and a sharp recovery. Revenue reached $11.7 billion in fiscal year 2022, then collapsed as cloud companies worked through stockpiles they had already bought. By fiscal year 2024, revenue had fallen to $6.6 billion, the lowest point in the data set. Cash from operations shrank from $1.7 billion in 2022 to $0.9 billion in both 2023 and 2024. Gross margin, which measures how much money is left after the cost of making the drives, fell from nearly 30% in 2022 to just 18% in 2023. That collapse in margin happened because Seagate had built factories and stocked parts for demand that never arrived, leaving expensive capacity sitting idle.
Seagate Annual Revenue (Fiscal Years 2021 to 2025)
Revenue in billions of dollars. The drop from 2022 to 2024 reflects a severe storage demand downcycle. The 2025 rebound was driven by higher cloud nearline drive shipments.
Fiscal year 2025 showed a strong reversal. Revenue climbed back to $9.1 billion, a 39% jump from the year before. Gross margin recovered to 35%, the best in this five-year period. Seagate shipped 595 exabytes of hard drive storage in 2025, up from 398 exabytes in 2024. That volume increase came almost entirely from mass capacity drives going to cloud customers. Net income reached $1.5 billion in 2025, compared to $335 million the year before. The recovery was real, but the business has not yet returned to its 2022 revenue peak.
35%
Gross margin in fiscal year 2025, up from 18% in fiscal year 2023, the full swing of the cycle in two numbers.
What is net debt?
Net debt is the amount a company owes to lenders after subtracting the cash it has on hand. A company with $5 billion in loans and $1 billion in cash has $4 billion in net debt. High net debt means a company must keep paying interest even when sales fall, which limits its options in a downturn.
One pressure that did not ease much during the downcycle is the debt load. Net debt stood at $4.2 billion in 2021, rose to $5.6 billion in 2022, and remained above $4 billion every year through 2025, ending at $4.1 billion. Seagate paid $321 million in interest expense in fiscal year 2025 alone. The company also carries $5.0 billion in future principal payments on its long-term debt and owes an estimated $1.8 billion in future interest. On top of that, Seagate is still paying off a $300 million penalty from a 2023 settlement with U.S. regulators over export violations, at $15 million per quarter over five years. These obligations do not disappear when the storage market softens.
$4.1B
Net debt as of fiscal year 2025, roughly unchanged from 2021 despite five years of cash generation.
What is HAMR technology?
HAMR stands for heat-assisted magnetic recording. A tiny laser heats a spot on the disk just long enough to write data more densely than older methods allow. Seagate calls its HAMR-based product the Mozaic platform. Higher density means more storage per drive, which lowers the cost per unit of storage for cloud customers.
The biggest near-term risk Seagate names is whether its new Mozaic hard drives, built on HAMR technology, work reliably at scale and qualify with major cloud customers on time. If Mozaic drives fail tests, ship late, or underperform, cloud buyers can turn to Western Digital or other competitors. A second concentrated risk is that a small number of very large cloud and hyperscale customers make up a large share of revenue. If any one of them delays orders or faces export restrictions, the revenue hit is immediate and hard to replace. A third risk is forecasting. Seagate must commit to building parts and filling factories three to six months before it knows how many drives customers will actually order. When those forecasts are wrong, idle factories create underutilization charges, exactly what happened in fiscal years 2023 and 2024. Finally, several key components, including rare earth materials and certain parts sourced from China, are either single-sourced or subject to trade restrictions that could disrupt production without warning.

The Demand Cliff
Revenue fell from $11.7 billion in fiscal year 2022 to $7.4 billion in fiscal year 2023, then further to $6.6 billion in fiscal year 2024. Cloud customers had over-ordered drives and stopped buying while they worked through inventory. Seagate's factories kept running, generating $160 million in underutilization charges in fiscal year 2024. The company also paid a $300 million regulatory penalty in 2023 for export violations. Together, these events compressed margins to their lowest point in this data set and forced Seagate to start requiring longer-term purchase commitments from customers to avoid a repeat.
The 2025 rebound was driven almost entirely by one thing: cloud customers resuming big purchases of high-capacity nearline drives. Mass capacity storage rose from 72% of revenue in fiscal year 2024 to 81% in fiscal year 2025. That concentration is both a strength and a vulnerability. When cloud spending is strong, it lifts everything. When it pauses, as it did in 2023 and 2024, there is not much else to cushion the fall.
355 exabytes
Mass capacity exabytes shipped (FY2024)
552 exabytes
Mass capacity exabytes shipped (FY2025)
A 55% jump in one year, driven by cloud nearline demand. Legacy market shipments were flat at 43 exabytes both years.
According to IDC, hard drives store 87% of exabytes in large data center deployments today. That share matters because it sets the floor for how long HDDs remain the default choice for cloud storage economics.
The Bet
Seagate's recovery holds only if cloud and hyperscale customers keep expanding their data centers at a pace that requires steadily more high-capacity hard drives, and if the Mozaic HAMR platform qualifies with those customers and ships at volume without reliability problems. Generative AI applications are supposed to accelerate data creation and storage demand, which would make that expansion durable rather than another short cycle. If cloud spending plateaus again before Mozaic is fully qualified and ramping, Seagate faces the same trap it fell into in 2023: factories built for demand that stopped arriving, with $4 billion in net debt and $321 million in annual interest still due regardless.
Open question
The storage market has recovered sharply, margins are up, and the Mozaic platform is in production. But Seagate has been through this before: a strong cycle followed by a sudden stop that turned excess factory capacity into a financial problem. The debt has not meaningfully declined, the customer base is concentrated, and the next generation of drives must prove itself at the scale cloud customers require. Is the current demand recovery durable enough, and is Mozaic reliable enough at volume, to keep margins above the break-even point through the next inevitable pause in cloud spending?

Product Development and Market Acceptance
The company must continuously develop new hard drive and storage products to keep up with customer needs and technological advances. If new products like the Mozaic hard drive platform with HAMR technology fail to work properly, qualify with customers, or reach the market on time, the company could lose significant sales and market share to competitors.
Customer Concentration
A small number of large customers such as hyperscale data center companies and cloud service providers account for a large portion of revenue. If any of these key customers significantly reduce purchases, delay orders, or are lost due to export regulations or other factors, the company's revenue and profitability could decline materially.
Demand Forecasting and Inventory
The company must invest in manufacturing and inventory three to six months before knowing if customers will actually buy the products. If demand forecasts are wrong or customers cancel orders, the company faces excess inventory, factory underutilization charges, and write-offs that can severely impact financial results, as happened in fiscal years 2023 and 2024.
Supply Chain and Component Sourcing
The company depends on suppliers for critical components like read-write heads, spindle motors, and rare earth elements, many of which come from China or are single-sourced. Supply shortages, tariffs, trade restrictions, geopolitical disruptions, or supplier failures could delay product manufacturing and shipments, forcing the company to cancel customer orders or lose market share.
Debt and Liquidity
The company carries significant debt and must use substantial cash flow to pay interest and principal. If cash flow from operations declines, the company may not have enough money to pay dividends, fund operations, or refinance debt, and covenants in debt agreements restrict the company's ability to borrow more money or make strategic investments.
