OPTIMIZERX CORPORATION
OPTIMIZERX CORPORATION is a Public Limited Company registered in United States under 001326687, and its current status with Massachusetts Secretary of the Commonwealth is active. The company was incorporated on 8 May 2018 and lists its registered address as United States. 2 shareholders are on record for OPTIMIZERX CORPORATION, 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 Massachusetts Secretary of the Commonwealth and was last updated on 4 October 2026.

Shareholders
2
Two shareholders are currently on record for OPTIMIZERX CORPORATION, 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 10.9% — the largest recorded stake — followed by Fidelity Salem Street Trust-Fidelity Small Cap Index Fund at 1.5%.
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 |

| Fidelity Salem Street Trust-Fidelity Small Cap Index Fund | 1.5% | Massachusetts Secretary of the Commonwealth |
Officers
5
The President & Ceo of OPTIMIZERX CORPORATION currently on record is Stephen L. Silvestro; five officers are currently on record for OPTIMIZERX CORPORATION, filed with Massachusetts Secretary of the Commonwealth.
The register reports 23 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at OPTIMIZERX CORPORATION 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
OPTIMIZERX CORPORATION has no recorded parent company — it sits at the top of its own group structure, with 4 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 4 subsidiaries span United States, Croatia 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.
