MAXCYTE, INC.
MAXCYTE, INC. is a Public Limited Company registered in United States under F06090815, and its current status with Maryland Department of Assessments and Taxation is active. Its registered address on file is Rockville, United States. 2 shareholders are on record for MAXCYTE, 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 Maryland Department of Assessments and Taxation and was last updated on 3 October 2026.

Shareholders
2
Two shareholders are currently on record for MAXCYTE, 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 Vanguard Group Inc, holding 8.5% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 1.6%.
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.

The President, Ceo & Executive Director of MAXCYTE, INC. currently on record is Maher Masoud; five officers are currently on record for MAXCYTE, INC., filed with Maryland Department of Assessments and Taxation.
The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at MAXCYTE, 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
MAXCYTE, INC. has no recorded parent company — it sits at the top of its own group structure, with 2 subsidiaries recorded beneath it across 2 jurisdictions. 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 2 subsidiaries span United States, United Kingdom jurisdictions, 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.
