# Spirent Communications ## Held through 1 documented hop to Keysight Technologies; 6 supply-chain edges and no export-control designation reaching it on the record Everything below is drawn from what the record carries for this organisation: its documented parents, the constraints that reach it, and the relationships and sites recorded against it. Each claim carries its source on the same line, and a blank means the record holds nothing. Cite PrintScreenshot 1 documented hop above it 6 supply-chain edges · 0 upstream, 6 downstream 0 tracked facilities operated 0 export-control designations reaching it 0 sovereign LP commitments reaching it Scrutica id org-spirent-communications LEI 213800HKCUNWP1916L38 ### Chain of title Each hop carries its data source, source URL (where one exists), as-of date, and confidence label on the same line as the parent name. When two sources name different parents for the same hop, both render as alternates; the walker picks no winner. 1. 1. Spirent Communications (GB)LEI 213800HKCUNWP1916L38 Starting entity. The walker climbs from here through documented parent / subsidiary edges. 2. 2. [Keysight Technologies](/companies/org-keysight-technologies) (US) Per [SEC EDGAR](https://www.sec.gov/Archives/edgar/data/1601046/000160104625000104/keysightacquiresspirento.htm), as of 2025-10-23 (HIGHtier 2): Keysight Technologies is the documented parent. Chain terminus [Chain-of-title](/methodology#chain-of-title-walk) terminates at **[Keysight Technologies](/companies/org-keysight-technologies)**. No further parent is documented. For a public filer that means ultimate beneficial ownership is the dispersed float; for a state-linked entity, that the chain has reached the sovereign apex. Chain visualization A visual companion to the walk beside it; the chain-of-title list is the citable artifact. 1. Spirent Communications (GB) 2. Keysight Technologies (US) SEC EDGAR · HIGH Ownership-change events Documented M&A-shaped events touching this entity (Buyout, Corporate Divestiture, Asset Sale, Joint Venture, Spin-off). Capital raises without an ownership transfer are excluded, because they do not move the chain. - Merger/Acquisition (Corporate Divestiture) 2002-09-27 · Completed· $24M Participant: TELEDYNE TECHNOLOGIES INCORPORATED; Seller: Spirent Communications ### Suppliers and customers Dollar flows are annual figures from the fiscal year labelled on the row, drawn from SEC segment and >10%-customer disclosures, re-derived company disclosures, or a licensed supply-chain database; per-row source and authority tier on hover. A row without a year means the source does not state the period. Disclosures older than 5 years are tagged _historical_ and ordered below current rows: they record what was disclosed then, and the counterparty may since have been acquired or dissolved. The 3-month Pearson r comes from a licensed supply-chain database; correlation is a coupling proxy for shared market sensitivity, and it is not a causal channel. Sole-source edges are flagged inline.

What is missing is one specific feed: the corporate-financials extract behind this profile (geographic revenue, segment mix, capital allocation), which is built from listed-company disclosures; Spirent Communications carries no listing or filer identifier, so there is no row for it to load. The public industry classification (SIC, NAICS) is absent as well. Coverage rules in the [methodology](/methodology#licensed-substrate).
