# Ribbon Communications ## No parent of record among the documented ownership edges; 7 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.

When two sources name different parents for the same hop, both render as alternates; the walker picks no winner. 1. 1. Ribbon Communications (US)CIK 1708055 · LEI 549300L1E8Z8RL7CUL52 Starting entity. The walker climbs from here through documented parent / subsidiary edges. Chain terminus [Chain-of-title](/methodology#chain-of-title-walk) terminates at **Ribbon Communications** (CIK 1708055 · LEI 549300L1E8Z8RL7CUL52). 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. ### 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 covers a loaded set of listed companies that Ribbon Communications is not among; the gap is in coverage, not in the record. The public industry classification (SIC, NAICS) is absent as well. Coverage rules in the [methodology](/methodology#licensed-substrate).
