Shares of Penguin Solutions surged nearly 16% to $74.33 on October 7, defying a softer broad market after the company delivered a blowout fiscal fourth quarter and dramatically raised its forecast for the year ahead.

  • The Beat Was Massive, Not Marginal. Penguin reported non-GAAP earnings of $1.00 per share on $566.7 million in revenue, crushing Wall Street estimates of $0.77 EPS and $521 million in sales.

The quarter set records across the board — net sales, operating income, net income, and adjusted EBITDA all hit all-time highs.

Revenue climbed 68% year over year while EPS jumped 133%, a sign that profits are growing faster than sales — exactly what shareholders want to see.

  • The Guidance Jump Is the Bigger Story. Management lifted its fiscal 2027 revenue midpoint to $2.43 billion, up from a preliminary $2.17 billion shared just last quarter.

Non-GAAP EPS is now expected at roughly $4.45, representing about 55% growth at the midpoint.

The company credited stronger bookings, a larger backlog, and faster growth in AI infrastructure demand for the upgrade. At $74.33, the stock trades at roughly 17x that forward EPS target — not cheap for a hardware-heavy business, but reasonable if the company delivers.

  • Memory Chips for AI Are Doing the Heavy Lifting. Integrated memory — specialty chips used in data centers running AI workloads — hit record sales of $341 million in Q4, up 158% year over year and now 60% of total revenue.

Management expects that segment to grow another ~50% in fiscal 2027. This concentration is a double-edged sword: it supercharges growth when AI spending is hot, but leaves the company exposed if data-center budgets cool.

  • The First Half Was Flat — The Second Half Saved the Year. Sales were essentially unchanged year over year in the first half before accelerating to 48% growth in Q3 and 68% in Q4, producing 58% second-half growth.

Full-year revenue rose 26% to $1.73 billion. That lopsided trajectory means the company's ability to sustain Q4's pace into fiscal 2027 is the question for investors. Penguin ended the year with $647 million in cash , providing a cushion — but execution, not liquidity, is what the market will be watching next.
