Optinose, Inc.
Optinose, Inc. is a Private limited company (Ltd.) registered in United States under 3977069, and its current status with Pennsylvania Department of State is active. The company was incorporated on 1 September 2010 and lists its registered address as Yardley, United States. 5 shareholders are on record for Optinose, Inc., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Pennsylvania Department of State and was last updated on 4 October 2026.

Shareholders
5
Five shareholders are currently on record for Optinose, Inc., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is FMR, LLC, holding 15.9% — the largest recorded stake — followed by Nantahala Capital Management, LLC at 14.6%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
| Shareholder | Type | Holding | Source Document |

| Nantahala Capital Management, LLC | 14.6% | Pennsylvania Department of State | |

Officers
5
The Ceo & Director of Optinose, Inc. currently on record is Ramy A. Mahmoud M.d., M.p.h.; five officers are currently on record for Optinose, Inc., filed with Pennsylvania Department of State.
The register reports 8 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Optinose, Inc. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
Optinose, Inc. sits 3 levels below its ultimate parent, Novo Nordisk Fonden, registered in Denmark. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to Novo Nordisk Fonden is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Optinose, Inc.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 1 subsidiary spans United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
