$PENG: Penguin Solutions Just Guided 40% Growth at a Mid-Teens Multiple. The Memory Cycle Is Both the Reason and the Risk

Penguin Solutions (Nasdaq: PENG) filed its fiscal fourth-quarter results after Tuesday's close: net sales of $566.7 million, up 68% year over year, non-GAAP earnings of $1.00 per diluted share against a consensus Benzinga pegged near $0.78, and a raised fiscal 2027 outlook calling for roughly 40% revenue growth. The stock had already climbed 5.8% during Tuesday's session on 15.4 million shares, about six times its recent daily volume, as the entire memory complex ran. By Wednesday's premarket it was trading near $66.66, up another 4% from the $64.21 close, and after the open it extended into the low $70s, up roughly 15% on the day.

Here is the tension the stream is trading around: a company that just grew 68%, guided to 40% growth next year, and raised that guide, trades at roughly 14 times its own forward non-GAAP earnings number. The S&P 500 trades well above that. Most things with "AI infrastructure" in the deck trade at multiples of it. Either the market is wrong about Penguin Solutions, or the market is telling you something about what kind of revenue this is. Both stories have evidence. That is what makes it worth pricing properly.

What Penguin Solutions Actually Is

Penguin Solutions is the company formerly known as SMART Global Holdings, renamed in late 2024, and it is really three businesses in one ticker. Advanced Computing is Penguin Computing, the original namesake: it designs, builds, deploys, and manages AI and high-performance computing clusters for enterprises, government, and increasingly the "neocloud" GPU-rental providers. This is the segment the AI story lives in, and the company says its ClusterWare management software now includes agentic AI capabilities that automatically detect and remediate GPU issues across inference environments. In the fourth quarter it did $154.0 million in sales.

Integrated Memory is SMART Modular, a specialty memory business: it buys DRAM and flash components and builds them into modules and subsystems for networking, telecom, industrial, and increasingly AI customers. In the fourth quarter it did $340.8 million, up 158% year over year, which made it 60% of the whole company. Optimized LED, the Cree LED business, contributed $71.9 million. Keep those proportions in mind, because they are the key to the valuation question.

There is also a strategic anchor worth knowing: SK Telecom closed a $200 million investment in Penguin Solutions in December 2024, taking convertible preferred stock with a $32.81 conversion price, a 6% dividend payable in kind, and a board seat. At Wednesday's prices that position has more than doubled, and SK Telecom's public commentary has framed Penguin as an operational partner in its AI infrastructure strategy, not a passive bet. A patient strategic holder with a board seat cuts both ways: validation on the way up, an eventual 6-million-share conversion sitting in the capital structure the whole time.

The Quarter and the Raise

The fiscal year ended August 28. Full-year net sales reached $1.73 billion, up 26%, with non-GAAP EPS of $2.87, up 51%, and adjusted EBITDA of $256.4 million. The acceleration profile is what management leads with: growth ran 48% in the third quarter and 68% in the fourth. The company says it added six new AI infrastructure customers in the quarter, including what it calls major neocloud providers, and highlighted an engagement deploying 36,000 GPUs for an AI lab customer.

For fiscal 2027, management guided to net sales growth of approximately 40%, plus or minus 10 percentage points, which works out to roughly $2.4 billion at the midpoint, with non-GAAP diluted EPS of approximately $4.45, up about 55% from the year just closed. The company called this a raise from the preliminary view it gave a quarter ago. Against Tuesday's $64.21 close and the roughly 63 million diluted shares the guidance assumes, that is a market capitalization near $4.0 billion, about 14.4 times the forward non-GAAP number and about 18.3 times the $3.50 GAAP figure. At Wednesday morning's price in the low $70s, the forward non-GAAP multiple is closer to 16 to 17 times.

So the setup: a beat, an acceleration, a raise, a strategic anchor shareholder, and a stock that, even after rallying to the low $70s on Wednesday morning, still sits roughly 18% below the $89.86 high it printed in early July. The question the multiple is asking is whether fiscal 2027's growth is AI infrastructure revenue that deserves a rerate, or memory-cycle revenue that deserves exactly the discount it is getting. The answer lives in the segment mix, the margin guide, and the balance sheet, and that is what the rest of this briefing prices out.
