Fact Summary
Astera Labs is a fabless company that designs connectivity semiconductors for AI data centers. In 2026 Q2 (released 2026-08-04), it recorded revenue of $392.4M (+104% YoY) and issued Q3 revenue guidance of $540M–$560M. FY2025 revenue was $852.5M, up +115.1% YoY, with operating income of $173.4M and net income of $219.1M, marking its first year of annual profitability (10-K, accession no. 0001736297-26-000010). In 2025, the single largest customer accounted for more than 70% of revenue (10-K).
Price Movement Context Note
On 2026-08-17, the stock opened +7.14% versus the prior day, reportedly driven by a rating change from an overseas research firm (Investing.com). Although the 2026-08-04 earnings release beat consensus EPS of $0.69 with $0.80, the stock fell -12% the following day (8/5), reportedly due to profit-taking after a four-consecutive-day rally ahead of the release (including +26.76% on 7/30) (Trefis).
Business Overview
| Product Line | Description | 2026 Q2 Trend |
|---|---|---|
| Scorpio | Fabric switches | Entering mass production of the X-Series (320-lane); expected to become the top revenue product line in 2026 Q3 |
| Aries | Signal-conditioning retimers and gearboxes | Recorded the highest quarterly revenue in 2026 Q2 |
| Taurus | For active cables | Strong revenue growth in 2026 Q2 |
| Leo | CXL memory controllers | Mass-production shipments to two US hyperscalers planned for 2027 |
PCIe 6.0-based products (Aries retimers + Scorpio fabric switches) accounted for more than 50% of 2026 Q2 revenue (up from about one-third in 2026 Q1; company earnings release, 2026-08-04). Customer concentration is high: in 2025, the single largest customer accounted for more than 70% of revenue, and the top three customers accounted for approximately 86% (10-K).
5-Year Financial Trends
| Period | Revenue | Operating Income | Net Income | Total Equity |

2026 first-half (H1) cumulative revenue was $700.8M (+99.4% year-over-year), operating income $151.1M (+195.9%), and net income $233.4M (+181.1%) — 10-Q (accession no. 0001736297-26-000035, as of 2026-06-30).
Valuation
ALAB's trailing P/E (163.97, per web sources) is significantly higher than Marvell's (60.45) and Credo's (96.00) — this can be interpreted as reflecting revenue growth (YoY in the 100%+ range) that is substantially higher than peers (factual statement). Key competitors include Broadcom, Marvell, Credo Technology, and Microchip Technology, among others; the global retimer market is projected to grow from $613.6M in 2024 to $1,022.2M in 2029, a CAGR of 10.7% (C, 360iResearch, MarketsandMarkets).
Supply and Demand
Institutional ownership estimates vary widely by source, from 60.47% (MarketBeat) to 92.26% (Fintel), reflecting differing methodologies; these are presented only as estimates (no single confirmed figure is available). Short interest decreased by 415,968 shares from the prior settlement date (2026-07-31, FINRA).
Governance and Capital Structure
| Date | Event |
|---|---|
| 2026-02-10 | CFO Michael Tate departure announced |
| 2026-03-02 | New CFO Desmond Lynch takes office |
| 2026-06-04 | Annual shareholder meeting — Class II directors (Gajendra, Barratt, Hurlston) up for re-election |
| 2026-07-01 | Director Manuel Alba sold 37,535 shares (approx. $16.79M) under a 10b5-1 pre-arranged plan |
| 2026-08-06 | Director Stefan Dyckerhoff sold 12,499 shares under a 10b5-1 pre-arranged plan (weighted average $308.67–$313.21) |
Co-founders Jitendra Mohan (CEO) and Sanjay Gajendra (COO) held stakes of 5.4% and 4.5%, respectively, as of 2025-09-30, with the majority of their holdings transferred into estate trusts (SC 13G/A). ALAB has a single-class common stock structure (one vote per share) and has never issued preferred stock (10-K, DEF 14A). Following an internal reorganization of Vanguard Group Inc. on 2026-01-12, under which affiliates began reporting individually, the parent entity's reported holding nominally dropped to 0% (a change in reporting method, not a divestiture, as explicitly stated in the source). Form 4 filings from 2026-05-17 through 2026-08-17 number approximately 24, mostly small dispositions (code S) for tax withholding related to RSU vesting, with no separate signal of voluntary large-scale disposals identified (factual observation).
Macro Impact
| Factor | Current Value | Direction of Impact |
|---|---|---|
| 2026 hyperscaler AI capex (Big Four combined) | Approx. $725B (+77% YoY) | Upside |
| Scorpio-X hyperscaler adoption | Adopted by 10+ customers; expected to become the top revenue product line in 2026 Q3 | Upside |
| US semiconductor export controls on China | 2026-05-31: Commerce Department expands closure of workaround channels | Downside (indirect) |
| TSMC CoWoS/HBM supply | CoWoS supply gap expected to narrow from 20% to the low double digits; HBM 2026 volumes fully allocated | Mixed |
ALAB is directly tied to the hyperscaler AI capex cycle, and the 77% YoY expansion in 2026 Big Four capex is immediately reflected in the 2026 Q3 revenue guidance (+40% quarter-over-quarter at the midpoint). The export controls on China target Nvidia's and AMD's sales into China, and no instance of direct regulation of ALAB has been identified; the 10-Q lists trade barriers affecting China and Taiwan as a risk factor.
Risk Factors
- Customer concentration: In 2025, the single largest customer accounted for more than 70% of revenue, and the top three customers accounted for approximately 86% (10-K)
- Geopolitical and export control risk: Manufacturing partners and a substantial portion of revenue are concentrated in Taiwan, China, and South Korea; the 10-K identifies as a risk factor the possibility that changes in US-China regulations could restrict sales into China
- Manufacturing supply chain: Dependence on a small number of foundry partners including TSMC (10-K)
- Valuation volatility: Beta (β) of 3.96 (C, aggregated web source), with a TTM P/E of 150.9x representing a premium to peers
- Insider selling: Reports indicate substantial insider (executive and director) share dispositions over the past three months (secondary sources cite figures of approximately $292M–$444.9M; no single confirmed figure is available) — most sales were made under 10b5-1 pre-arranged plans
- Earnings volatility: Despite 2026 Q2 results beating consensus and guidance being raised, the stock fell -12% the day after the earnings release (2026-08-05) — illustrating share-price sensitivity to the gap between pre-priced expectations and actual results
