Penguin Solutions closed out its fiscal year with a quarter that looked more like a growth stock’s highlight reel than a hardware company’s earnings report. Fourth-quarter net sales hit $567 million, up 68% from the same period a year earlier.
Management then raised its fiscal 2027 sales and earnings outlook.
The quarter in numbers
Penguin Solutions (NASDAQ: PENG) reported non-GAAP diluted earnings per share of $1.00 for the fiscal fourth quarter. That figure topped analyst estimates by $0.23.
The standout was the Integrated Memory segment, where revenue climbed 158% year-over-year. The company also added six new AI infrastructure clients during the quarter.
For the full fiscal 2026, Penguin generated net sales of $1.73 billion, a 26% increase over the prior year. Non-GAAP EPS rose 51% to $2.87.
Full-year sales grew 26%, while the final quarter alone grew 68%. Momentum built through the year instead of fading.
The company tied that acceleration to rising demand across its Integrated Memory and Advanced Computing businesses, especially in the back half of the fiscal year. New customers and the adoption of newer memory technologies used in AI infrastructure drove much of the lift.
A bigger number for fiscal 2027
Penguin now projects approximately $2.43 billion in net sales at the midpoint, which would mark around 40% growth. On the earnings side, the company expects non-GAAP diluted EPS of $4.45, roughly a 55% increase. Both figures came in above previous estimates.
Investors liked what they saw. Shares rose 5-6% immediately after the release, with the stock climbing to $64.21 on Oct. 6, a 5.8% gain on the day of the announcement.
Where Penguin fits in the AI hardware stack
Penguin positions itself as an AI infrastructure specialist. Its work centers on semiconductor and memory technology, along with advanced computing systems.
The fiscal 2026 results show a company whose growth tilted sharply toward AI-related demand as the year went on. The fourth quarter alone accounted for nearly a third of full-year sales.
What this means for investors and the AI infrastructure trade
For PENG shareholders, the raised guidance is the headline. Penguin now targets approximately 40% sales growth and around 55% EPS growth for fiscal 2027.
The six new AI infrastructure clients added in Q4 are worth watching closely. A broadening client base reduces customer concentration risk.
Watch the company’s quarterly updates for three things: continued growth in Integrated Memory, the pace of new AI client wins, and whether management holds or adjusts the $4.45 EPS target.
