$303.25+9.69 (+3.3%)
Close on Sep 18, 2026. Page updated Sep 19, 9:17 pm ET.
Gekko Brief
AI summaryAstera Labs closes at $303.25, up 3.3%, sitting just below its 50-day average of $305.38 and well above its 200-day average of $231.19. The GekkoIndex reads 56.6, placing the stock in the Neutral zone, down 3.2 over five sessions. Shares trade 10.6% below Gekko Fair Value of $339.21, a gap that leaves room relative to the model estimate.
This week's coverage centers on product expansion and competitive positioning. Astera Labs broadened its Leo CXL memory controller lineup with a new X-Series aimed at agentic AI workloads, building on hyperscaler design wins in AI infrastructure connectivity. Coverage also framed the stock against peers including Arm and KLA on growth and upside comparisons, while one report noted shares falling 10.1% intraday on 14 September. Together the items concern new product rollouts in the Leo and Scorpio families alongside ongoing comparisons to sector peers.
Over the next 20 trading days, the next earnings report falls outside that window, due 3 November after the close, 44 days away; the prior quarter's EPS of $0.29 missed the $0.42 estimate, with an average absolute reaction of 13.1% across recent reports. In the last 30 days there have been 3 unusual options signals, with call premium of $10,418,076 against put premium of $4,048,306. Analyst coverage stands at 11 buy and 5 hold ratings among 16 firms, with a consensus target of $389.95.

Last earnings call, Aug 4, 2026 AI summary
- What they said
- Astera Labs reported a very strong Q2 FY2026 with record revenue of $392.4 million (up 27% sequentially and 104% year-over-year). Growth was broad-based across its AI fabric (Scorpio family) and signal conditioning (Aries, Taurus) portfolios, with PCIe 6.0 products representing over 50% of revenue. Scorpio X-Series (high-radix AI fabric switches) entered volume production and is ramping faster than previously expected, with management expecting Scorpio to be the largest product family in Q3. Aries retimers set a new quarterly revenue record driven by both Gen5 and Gen6 adoption. Management emphasized software (COSMOS) enabling in-network compute and Hyper-cast capabilities, improving workload performance and customer stickiness. The company reported strong non-GAAP gross margin (73.7%), non-GAAP operating margin (39.1%), non-GAAP net income of $145.8M and EPS of $0.80 for Q2. Cash and marketable securities totaled approximately $1.25 billion. Management discussed product roadmaps including UALink, CXL (Leo), optics (NPO/CPO), and continued investment in silicon photonics and software. Q&A reinforced broad customer interest, multiple customer engagements (>10 on Scorpio X), and the expectation of material scaling in H2 and into 2027 for new product families.
- Guidance
- Q3 gross margin guidance: approximately 72% (non-GAAP). Management expects Scorpio to become the company's largest product family starting in Q3, with Scorpio X-Series scaling materially in H2. Management also guided that CXL (Leo) products are expected to ramp more materially in 2027, and that additional Scorpio X customers will ship by year-end. No explicit revenue or EPS numeric guidance for Q3 was provided in the transcript beyond product ramp timing and margin guidance.
- Risks flagged
- Forward-looking statements are subject to standard risks and uncertainties (as noted in the opening remarks and SEC filings). Specific risks discussed or implied include: design qualification and timing risk for customer ramps, customer concentration (lead hyperscaler(s) driving meaningful early volumes), evolving protocol/technology transitions (PCIe → UALink → CXL) and ecosystem readiness, supply chain and memory availability/cost dynamics, and execution risk tied to scaling new silicon, software integration, and optical/NPO/CPO transitions.
