Seagate $STX Seizes 36% Revenue Growth with AI Storage Demand Surge

The surge in artificial intelligence workloads has created an insatiable demand for data storage, positioning companies like Seagate Technology Holdings plc (NASDAQ: STX) at the forefront of a critical, if under-discussed, segment of the tech ecosystem. While much of the market’s attention fixates on compute power and chipmakers, the infrastructure that sustains the vast datasets powering AI models deserves equal scrutiny. Seagate, a veteran in mass-capacity storage, has shown robust financial performance in fiscal 2025, with revenue growth and margin expansion reflecting both operational discipline and a favourable demand environment. This analysis delves into Seagate’s recent results, its strategic positioning, and the broader storage industry dynamics driven by AI.

Financial Performance: A Strong Fiscal 2025 So Far

Seagate’s financial trajectory through the first three quarters of fiscal 2025 (ending March 2025) paints a picture of resilience and strategic execution. In the fiscal second quarter (Q2, October to December 2024), the company reported revenue of $2.33 billion, a significant year-on-year increase, alongside a non-GAAP diluted earnings per share (EPS) of $2.03. This followed a solid fiscal first quarter (Q1, July to September 2024) with revenue of $2.17 billion and non-GAAP EPS of $1.58. The third quarter (Q3, January to March 2025) saw revenue slightly dip to $2.16 billion, but non-GAAP EPS remained strong at $1.90, supported by operating cash flow of $259 million. Notably, gross margins reached decade-high levels across these quarters, a testament to pricing power and cost control in a tightening supply-demand balance for high-capacity drives.

The company’s focus on heat-assisted magnetic recording (HAMR) technology, embedded in its Mozaic platform, has been a key driver. HAMR enables higher areal density, allowing Seagate to meet the escalating storage needs of cloud providers and data centres. The rollout of 28-terabyte nearline drives in Q1 and broader adoption by cloud customers signal a structural shift in product mix towards premium offerings, which bolster margins.

AI Workloads and the Storage Imperative

The exponential growth of AI models, which require vast datasets for training and inference, has amplified the need for mass-capacity storage. Data centres supporting generative AI applications are not merely compute hubs; they are repositories of petabytes of information that must be accessed at scale. Seagate’s Exos and IronWolf Pro drives, with capacities now reaching 30 terabytes as announced in July 2025, are tailored for such environments. This positions the company to capture a growing share of the storage market, particularly as hyperscalers expand infrastructure to meet AI-driven demand.

Industry estimates suggest that global data creation will continue to grow at a compound annual rate exceeding 20% through the end of the decade, with AI workloads contributing significantly. Seagate’s ability to scale production of high-capacity drives, while maintaining margin discipline, will be critical. The company’s recent channel availability of 30-terabyte drives underscores its readiness to address this surge, though competition from peers like Western Digital remains a factor to monitor.

Valuation and Market Sentiment

Seagate’s valuation metrics reflect a blend of growth and caution. With a price-to-sales ratio hovering around 3.7 times and reported revenue growth of approximately 36% year-on-year in recent quarters, the stock appears reasonably priced relative to its growth trajectory. Operating margins, averaging around 19% in fiscal 2025, further support the case for operational efficiency. Sentiment on platforms like X, including observations from accounts such as Mindset for Money, CPA, highlights a growing recognition of storage as a vital cog in the AI ecosystem, though it often remains overshadowed by more glamorous sectors like semiconductors.

The table below summarises Seagate’s key financial metrics for fiscal 2025 to date:

Risks and Challenges

Despite the bullish outlook, Seagate faces headwinds that warrant caution. Supply chain constraints, though easing, could still disrupt production ramps for HAMR-based drives. Additionally, while AI-driven demand is robust, any slowdown in hyperscaler capital expenditure could temper growth. Competitive pricing pressures, particularly in lower-capacity segments, may also challenge margin sustainability. Investors should note that while fiscal 2025 guidance remains optimistic, with forward revenue growth projected at around 25% over the next two years by some analysts, macroeconomic volatility could alter this trajectory.

Conclusion: A Quiet Giant in the AI Era

Seagate Technology stands as a compelling player in the data storage landscape, capitalising on the AI boom with a combination of technological innovation and financial discipline. The company’s decade-high margins and consistent revenue growth through fiscal 2025 reflect a business model well-aligned with market needs. As data becomes the lifeblood of AI, storage providers like Seagate are likely to emerge from the shadows of compute-focused narratives. For investors, the balance of growth, valuation, and execution risk presents a nuanced but attractive proposition. The upcoming fiscal Q4 and full-year 2025 results, scheduled for release on 29 July 2025, will provide further clarity on whether this momentum can be sustained.
