The clearest sign of how tight the market for AI memory chips has become came on an earnings call in early October, when Kash Shaikh, the chief executive of Penguin Solutions, told analysts something that would have sounded impossible two years ago. The company’s memory backlog, he said, now exceeds the revenue it books in a quarter, and the orders already on hand will take at least four more quarters to deliver.
Penguin Solutions, a Fremont, California-based provider of computing and memory systems for AI data centers, reported record memory revenue of 341 million dollars for its fiscal fourth quarter, up 158 percent from a year earlier. The memory business accounted for 60 percent of the quarter’s 567 million dollars in net sales and 53 percent of revenue for the full fiscal year 2026, which ended August 28. Full-year revenue rose 26 percent to 1.73 billion dollars, and earnings per share reached 1.00 dollars, up 133 percent.
The driver is straightforward: the memory that AI data centers need is in short supply, and supply is not catching up with demand. The company said bookings grew faster than sales during the quarter, and it finished the year with a record company-wide backlog and what management described as strong momentum heading into fiscal 2027.
The surge arrived late. Shaikh told investors the company’s performance accelerated sharply in the second half of the fiscal year after the launch of its AI Factory Platform and a tighter focus on the data center market. After relatively flat sales in the first half, growth reached 48 percent in the third quarter and 68 percent in the fourth.
The constraint begins upstream. SK Hynix, the South Korean chipmaker, is one of Penguin Solutions’ principal memory suppliers and the dominant producer of the high-bandwidth memory that goes into AI accelerators. When SK Hynix’s output is rationed across its customers, the effect flows down to the module makers and system builders that package memory for data centers, and from there to the end users who cannot get chips fast enough.
The result is a market in which the bottleneck has moved from demand to supply. Data center operators want far more memory than the industry can make, and the gap shows up as rising prices and lengthening delivery times. Penguin’s management said both prices and volumes rose during the quarter, which pushed revenue to a record even as the value of unfilled orders kept climbing.
For the company, the backlog is a double-edged fact. It guarantees revenue for at least the next year, which is why management raised its outlook and guided to memory revenue growth of about 50 percent at the midpoint of its range. But it also means Penguin cannot take on new demand quickly, and it leaves the company exposed if the current shortage eases and customers who over-ordered start canceling.
The memory shortage is part of a broader scramble in the AI supply chain. Every hyperscaler is racing to add capacity, and the components that feed that build-out, from memory to power equipment, are stretched. Penguin’s experience is a local example of a global condition: demand has outrun the supply of nearly everything a data center needs.
The company has been repositioning itself around this demand for years. Once a broader hardware and services firm called Smart Global Holdings, it adopted the Penguin Solutions name in 2024 and now concentrates on what it calls integrated memory and AI infrastructure, the two categories that made up 78 percent of quarterly sales and grew 141 percent from a year earlier. It has also begun working with SK Hynix on next-generation CXL memory, an emerging standard that lets servers pool and share memory across machines. If CXL catches on, it offers data center operators a way to stretch scarce chips further, and it gives Penguin a second line of business to sell into the same customers.
Investors have rewarded the shift. The stock rose after the company beat estimates for the quarter, and the decision to raise guidance reflects management’s confidence that the backlog will hold.
The risks are easy to name. Inventory rose sharply during the year, from 255 million dollars to 749 million dollars, as the company stocked components ahead of expected demand. If the cycle turns, that inventory becomes a liability. Memory is a commodity with a history of violent swings, and the same shortage that is lifting Penguin today has lifted and then crushed its suppliers before.
For now, though, the direction is clear. The company has sold more memory than it can deliver in a quarter, its largest supplier is rationed, and the orders on its books stretch a year into the future. The unanswered question is how long a market this tight can last, and who gets caught holding inventory when it finally loosens.
