PENG Deep Dive — October 7, 2026

Verdict: Justified

Key finding: This is a real earnings catalyst. Fiscal Q4 (reported after the close 10/6) set records: revenue $567M (+68% YoY) vs about $516M expected, and adjusted EPS $1.00 vs $0.78. FY27 guidance came in far above expectations: revenue $2.25-2.60B vs $2.20B expected, EPS $3.75-5.15 vs $3.25. The driver is Integrated Memory: $341M, +158% YoY, from AI inference / agentic-AI memory demand, with memory backlog covering at least four quarters. Today's high of $76.00 broke the $65.75 August base high on 19.3M shares (about 10x the average). The stock is still at only about 16x the guidance-midpoint EPS.

Note: our fundamentals table shows PENG's latest-quarter EPS as 0.00 and shares as 0, which is a data gap. EPS shown above is the company's reported adjusted figure.

PENG is the growth-at-a-low-price name of the AI storage/server group.
- Revenue growth is accelerating (+47.6% → +67.7%), second only to SMCI.
- It has the second-lowest P/S (2.15).
- Op margin tripled in a year (3.7% → 11.5%).
- It is the smallest name (market cap $3.7B), so it moves the most.
- Gross margin (~28%) is far below NTAP/P (~70%), because this is memory/hardware rather than software-like storage.

Move

Run-up: from the $16.04 March low to the $89.86 high on 7/9, after the July 7 earnings (that report: gap +8.2%, day-1 +25.1%).
Pullback: to the $45.62 September low (-49.2%).
Base: $45.62-$65.75 through August and September.
10/6 (before the print): 15.0M shares, range $56.60-$64.58, close $64.21 (+5.8%). I found no pre-print news for that volume (unknown; inference: positioning into earnings).
10/7 (reaction day): opened $67.28 (gap +4.8%), low $65.70, high $76.00 (+18.4%). Trading at $72.93 (+13.6%) at 15:34 ET on 19.3M shares (average about 2.0M).
Above the 50-day ($53.64) and 200-day ($40.16) MAs. Overhead: the June high $77.40, the July gap zone ~$80-83, and the high $89.86.

Catalyst

Earnings were reported after the close on 10/6 (per the FMP earnings calendar).
- Q4: net sales $567M (+68%). Records for sales, gross profit ($163M, +57%), operating income, margin, net income and adjusted EBITDA.
- Segments: Integrated Memory $341M (+158%), Advanced Computing $154M (+11%).
- Gross margin: 28.8%, up 70bp from the prior quarter.
- FY27 guidance: revenue $2.25-2.60B (midpoint $2.43B, about +40%) vs $2.20B expected. EPS $3.75-5.15 vs $3.25 expected.
- Backlog: record company-wide backlog; memory backlog covers at least four quarters.
- Story: management says agentic AI and inference are a structural driver of memory demand, with demand outpacing supply (pricing power). MemoryAI CXL KV-cache servers (launched March 2026) are ramping faster than expected; target is over 10% of Memory revenue exiting FY27 (about $50-60M a quarter) and a path to about $300M in FY28.
- Analysts raised estimates after the print. I couldn't read the individual price targets (Benzinga returned 403), so they are unknown.

Sector

AI storage/servers / memory was the #3 durable theme in the 10/6 monthly report: P 3M +88%, QMCO +230%, NTAP +38%, DELL/SMCI/HPE. Today NTAP is +2.4% while high-beta sells off.
Memory is in a pricing upcycle driven by AI inference (Micron, SanDisk, Seagate have doubled or tripled in 2026 per earlier research).
The market is risk-off today (SPHB -1.8%, /ES at the top of its multi-year channel). PENG +13.6% against that tape is real relative strength.

Risks

The July replay: the last earnings pop (D1 +25.1%, high $89.86) gave back 49% in two months. Earnings gaps in this name have faded before.
Memory-cycle exposure: about 60% of Q4 sales are Integrated Memory, priced off the DRAM/NAND cycle. If memory prices roll over, margins and guidance go with them.
Low gross margin (~28%): a hardware integrator, so less pricing power than storage software peers.
Advanced Computing only +11%: legacy wind-downs offset AI wins there.
Wide guidance range: EPS $3.75-5.15 is a 37% spread, so the low end is the bear case.
Supply / dilution: the data shows no recent offering, and diluted shares are flat at about 53-55M. I didn't check the capital structure (preferred / converts) in this dive, so it's unknown.
Next binary: fiscal Q1 earnings, about early January 2027 (inference from the April/July/October pattern).

Judgement

The move is justified.
- It's a beat-and-raise with guidance well above expectations, and it's backed by a four-quarter memory backlog.
- At $72.93 the stock is about 16.4x FY27 guidance-midpoint EPS ($4.45) (my calculation). That's cheap next to NTAP (31.6x trailing) and P (179.6x).
- The price confirms it: a base breakout on about 10x volume on a risk-off day.

It's a real catalyst, with a gap-and-go through a 2-month base.
