Undervalued and Profitable: This Artificial Intelligence (AI) Stock Has Soared 73% in 2025, and It Could Still Jump Higher
The booming demand for data center storage has supercharged Seagate Technology's growth in recent quarters, leading to tremendous upside for the stock. Seagate is trading at a discount to the broader market right now, and that could pave the way for attractive returns over the next several years. 10 stocks we like better than Seagate Technology Plc › Storage solutions provider Seagate Technology (NASDAQ: STX) has registered an outstanding rally on the stock market in 2025, rising an incredible 73% year to date and beating the Nasdaq Composite index's 7% return by a massive margin. This impressive performance can be attributed to robust growth in the demand for storage in data centers running artificial intelligence (AI) workloads. Let's dig into how AI is fueling Seagate's growth and see how it could pave the way for more upside in this technology stock. Seagate Technology's revenue in the first nine months of its fiscal 2025 increased almost 43% year over year to $6.65 billion. Even better, the company's non-GAAP (adjusted) income from operations has jumped more than fourfold during this period, thanks to higher margins. Management attributes this fantastic growth to the healthy demand for mass capacity storage in the cloud, which has created a tight supply environment and led to an increase in prices. Management remarked on the company's April earnings call that the growing storage demand "aligns with the cloud capex investment cycle and ongoing build-out of data center infrastructure to support AI transformations." Specifically, 90% of the storage in large-scale data centers is done with hard drives because of their cost efficiency and scalability. With the storage requirement in data centers expected to more than double between 2024 and 2028, Seagate estimates this could push annual revenue for the data center storage market to $23 billion by 2028, up from $13 billion last year. Seagate is in a solid position to make the most of this growth opportunity considering its 40% share of the global storage market. Not surprisingly, Seagate's outlook for the recently concluded fiscal fourth quarter was an impressive one. The company guided for $2.4 billion in revenue at the midpoint of its range, along with $2.40 per share in earnings. The top-line guidance is good for a 27% year-over-year increase, while earnings are on track to more than double from the prior-year period's reading of $1.05 per share. For the full fiscal year, Seagate could grow revenue 38%, while its adjusted earnings will jump more than sixfold to $7.91 per share. Importantly, the company should be able to sustain this momentum, thanks to the tailwinds discussed above, and that sets the stage for strong returns. The potential earnings growth combined with Seagate's incredibly attractive valuation makes the stock a no-brainer buy. It is now trading at just 21 times trailing earnings and 16 times forward earnings estimates. The Nasdaq 100 index, meanwhile, has an average forward earnings multiple of 29, which means the stock trades at a significant discount to the tech sector overall. Investors looking for a fast-growing AI stock that's also reasonably priced would do well to buy Seagate before it flies higher.

IT pioneer Pure Storage recently announced an expansion of its next-generation storage product portfolio designed for demanding and high-performance workloads. 'In an era where data is king and IT complexity remains a major hurdle to accessing and using data for optimal business value, Pure Storage is once again redefining what's possible for customers', said John Colgrove (Coz), Founder and Chief Visionary at Pure Storage. 'Pure Storage delivers the magic by rejecting the norms we've come to accept for storage infrastructure; they are what's holding us back within this new era of exponential data growth and logarithmic growth of insight value'. As data volumes rise and business demands shift faster than ever, traditional storage infrastructures create fragmentation, silos, and uncontrolled data sprawl. Organisations must fundamentally change their approach to data storage and management to one that nimbly and efficiently helps customers meet and scale growing data needs. An Enterprise Data Cloud (EDC) redefines how data is delivered, governed, and consumed by creating a virtualized cloud of data delivering a single, seamless data layer with consistent control across on-premises, public cloud, and hybrid environments. Only the Pure Storage platform offers the performance, efficiency, and intelligence to deliver such data management at scale. FlashArray and FlashBlade – Built To Do More Core to the Pure Storage platform are Pure Storage FlashArray™ and Pure Storage FlashBlade®, which underpin the delivery of performance, reliability, and flexibility in a unified storage experience. The latest Pure Storage FlashArray and Pure Storage FlashBlade offerings extend the platform — unlocking massive performance density gains, enabling faster results, and seamlessly scaling for future applications and demands — with capabilities to handle the full workload spectrum. NEW: Pure Storage FlashArray//XL The next generation of Pure Storage FlashArray, FlashArray//XL™ R5, sets the bar for performance at extreme scale so customers can consolidate diverse workloads into a unified platform. FlashArray//XL: Doubles the amount of IOPS (Input/Output Operations Per Second) per rack unit compared to the previous generation and increases max raw capacity by up to 50 percent. NEW: Pure Storage FlashArray//ST Continuing to push the boundaries of high-performance platforms, FlashArray//ST™ is a new offering designed to serve the most latency-sensitive workloads such as in-memory databases, large OLTP, log writing, and scale-out and sharded NOSQL databases. FlashArray//ST: Delivers over 10 million IOPS per five rack units through an optimized IO path. NEW: Pure Storage FlashBlade//S Next-generation controller blades in FlashBlade//S™ R2, the latest version of Pure Storage FlashBlade//S, enhance the platform to help organizations accelerate time-to-insight, consolidate infrastructure, and realize faster outcomes from the most demanding data pipelines. FlashBlade//S: Performs up to 30% greater than competitors across critical workloads like genome sequencing, inference, and electronic design automation simulations, as well as other extensive datasets required for effective AI reasoning. NEW: Single Architecture of Block, File, and Object Addressing the explosive growth of unstructured data, Pure Storage extends object support to FlashArray, creating a true single architecture for block, file and object across the entire Pure Storage platform. Object support for FlashArray: Simplifies data management with block, file, and object consolidated on a single unified platform and consistent experience. 'Pure Storage was born to disrupt the industry, as we introduced new capabilities to reliably achieve better and better performance at any scale', continued Colgrove. 'We are unwavering in our mission to enable our customers' ambitions, providing the most innovative and reliable foundation they need to confidently meet any future challenge or opportunity'.
