You are looking at Astera Labs, Inc. — technology name listed on NASDAQ as ALAB. Below is a read of the latest Form 13F tape (period of report 2026-06-30, Q2 2026) versus the prior quarter (2026-03-31, Q1 2026), plus a short company overview.
Astera Labs, Inc. / ASTERA LABS INC
What changed in Q2 2026?
Last quarter = Q2 2026 (period of report 2026-06-30) versus prior Q1 2026 (2026-03-31). Figures are reported 13F values (USD) as filed — delayed snapshots, not live prices.
Here is the story in one breath: more 13F filers (986 vs 691), and the aggregate reported 13F value rose (about $58.27B from about $11.37B). Total disclosed shares also moved to about 126,100,652 from about 105,780,060. Hedge-style* holders numbered 17 in Q2 2026 versus 12 in Q1 2026. On the full 13F tape, 388 managers entered and 93 exited (hedge-style* enter/exit: 10 / 5).
Status mix across the QoQ tape (1,079 manager rows including exits): 388 ENTERED, 93 EXITED, 273 INCREASED, 253 DECREASED, 72 UNCHANGED.
Reporting-entity note: several Vanguard-affiliated names appear as ENTERED under new CIKs in Q2 2026 (for example VANGUARD PORTFOLIO MANAGEMENT LLC ($3.81B), VANGUARD CAPITAL MANAGEMENT LLC ($3.25B), VANGUARD FIDUCIARY TRUST CO ($427.39M), VANGUARD ASSET MANAGEMENT, Ltd ($141.36M)). That is a 13F filer / CIK event in this tape — not automatically the same thing as “Vanguard never owned ALAB before.” Read it as new reporting entities showing up for this CUSIP in the QoQ join.

Company AI overview — Astera Labs, Inc.
Astera Labs, Inc. designs semiconductor-based connectivity solutions for rack-scale AI and cloud infrastructure. Common stock trades on NASDAQ as ALAB. HQ: 2345 North First Street, San Jose, California 95131, with additional sites across the U.S., Europe, Israel, India, and Asia listed on the company contact page (asteralabs.com; ir.asteralabs.com).
Short history / what they do. Astera Labs positions itself as an AI-infrastructure connectivity specialist. Company materials describe an Intelligent Connectivity Platform that integrates standards-based technologies such as PCIe, CXL, Ethernet, NVLink Fusion, and UALink with the company's COSMOS software suite — plus custom connectivity work for hyperscalers that need tailored fabrics.
Business model & revenue streams. Revenue comes from selling connectivity semiconductors and related software / platform offerings into AI rack and cloud builds. Product families highlighted in recent company commentary include signal-conditioning / retimer-style lines (e.g., Aries) and fabric switches (Scorpio X-Series). Mix can shift quickly as new platforms ramp.
Competition. Peers sit across high-speed interconnect, networking silicon, and custom ASIC / connectivity vendors selling into the same hyperscale AI build-out. Competition is about bandwidth, latency, standards support, and how easily a chip drops into a customer's rack design.
Moat (humble take). Design-wins, standards leadership, and software that ties multi-protocol links together can be sticky once a platform is qualified. Customer concentration, product ramps, and rival interconnect roadmaps can still move results fast.
Challenges & opportunities. Challenges include execution on multi-product ramps, customer concentration typical of AI infra suppliers, and keeping pace with evolving fabric standards. Opportunities track AI rack-scale connectivity demand, fabric-switch adoption, and custom solutions / optical interconnect expansion where the company discloses them.
Recent update (company). On 4 Aug 2026, Astera Labs reported Q2 FY2026 (ended 30 Jun 2026) revenue of $392.4M (+27% QoQ, +104% YoY), GAAP gross margin 73.3%, GAAP operating income $89.2M, GAAP net income $153.1M, and GAAP diluted EPS $0.83. Management pointed to broad strength across AI fabrics and signal conditioning and said Scorpio fabric switches were expected to become the largest product family in Q3.
