MPR ASSOCIATES, INC.
MPR ASSOCIATES, INC. is a United States engineering and management consulting firm whose principal office is at 320 King Street, Suite 400, Alexandria, Virginia 22314. The record holds Virginia State Corporation Commission identifier F1095134 and shows the registration as active as of 29 September 2026. Neither the identifier nor the status could be re-checked against the register: cis.scc.virginia.gov refused connections from this environment on 30 September 2026 over two separate network paths. Federal contractor records for the same entity (UEI LAD4BX6JCMS8, CAGE 6B701) give Virginia as its state of incorporation and the United States as its country of incorporation, and record it as a corporation. The stored legal-form and city fields are empty; that reflects the provider’s coverage rather than anything about the company.
MPR Associates’ own history dates the firm to September 1964 in Washington, DC, and places it at 320 King Street since 1992. The stored incorporation date of 1 January 1964 is a 1-January placeholder, and no primary source consulted gives a date of incorporation. The company lists four offices: Alexandria, Virginia; East Lyme, Connecticut; Burlington, Massachusetts; and Salt Lake City, Utah. Federal spending records show approximately USD 150.4 million of prime-contract obligations to MPR ASSOCIATES, INC. between 1 October 2015 and 29 September 2026, almost entirely under NAICS 541330, Engineering Services, with the Department of the Army and the Department of the Navy the largest awarding agencies. The US Nuclear Regulatory Commission inspected the Alexandria facility’s quality assurance programme from 6 to 10 March 2023; the NRC’s letter of 13 April 2023 describes the inspected scope as safety-related engineering and design services, software development, commercial-grade dedication services, and Basler excitation systems and associated components for US nuclear power plants.
A separate organisation of the same name should not be read as this company. MPR Associates, Inc. of Berkeley, California prepared education-statistics reports for the US Department of Education, among them NCES 2003-167 of August 2003. It is a different business in a different field, and records filed under that name do not belong to the Alexandria engineering firm.

Shareholders
Shareholders of MPR ASSOCIATES, INC.
No shareholder is disclosed, and two separate things are true here that should not be run together. First, the data provider supplied nothing: its shareholder record for MPR ASSOCIATES, INC. is an empty stub with no rows. Second, and independently, Virginia does not publish shareholder identities. The annual report that every Virginia corporation and every foreign corporation authorised in the Commonwealth must file under Code of Virginia § 13.1-775 sets out the corporation’s name, principal office, jurisdiction of formation, registered office and agent, its directors and principal officers, and the aggregate number of shares it is authorised to issue. It does not name who holds those shares.
MPR ASSOCIATES, INC. is privately held. A search of the SEC’s EDGAR company database on 30 September 2026 returned no company matching the name, so for this entity there is no proxy statement, no 5% beneficial ownership table, and no Schedule 13D or 13G. Federal contractor registration data carried into USAspending.gov records the company as a subchapter S corporation. The Internal Revenue Service states that an S corporation must be a domestic corporation, may have no more than 100 shareholders, may have only one class of stock, and may have as shareholders only individuals, estates and certain trusts — not partnerships, corporations or non-resident aliens. That constrains the shape of the ownership; it identifies nobody, and it is a self-certified registration field rather than a filed share register. Nothing above shows that the company has no shareholders. It shows that its share register is private.
Data availability
Shareholders: Not public — the jurisdiction does not publish shareholder or beneficial-ownership information for a privately held corporation, and the provider separately supplied no rows. Beneficial ownership: also not public. The United States operates no public beneficial-ownership register; beneficial ownership information reported to the Financial Crimes Enforcement Network is held in a non-public system, and Virginia’s corporate filings do not record beneficial owners. No ultimate beneficial owner of MPR ASSOCIATES, INC. can therefore be stated, and none is asserted.

Officers
5
Directors and officers of MPR ASSOCIATES, INC.
The provider supplies five officer rows out of a stated total of twelve, so the set is truncated and no conclusion about the full board or officer slate can be drawn from it. Every row is flagged active, none carries an appointment date or a resignation date, and no filing reference or effective date is given, so the vintage of the snapshot cannot be established. The addresses are mixed: three rows use the company’s own Alexandria business address at 320 King Street, one row carries no address at all, and one row carries a Connecticut address in Torrington that matches none of the four offices MPR publishes. A set assembled from mixed addresses, with no dates and no filing reference, is not a register extract.
The titles in the rows — President, Vice President, Secretary, and one row titled simply “Officer” — also do not match what the company itself publishes: its leadership page describes the firm as led by three Principal Officers. The officers of record for this company are whoever appears on its Virginia annual report, which under Code of Virginia § 13.1-775 must give the names and post-office addresses of the directors and the principal officers. That register could not be read on 30 September 2026, so no individual is named in this profile. A corporate leadership page is not a filing and has not been used as one.
Data availability
Partial, undated and unverified. Virginia does publish director and principal-officer names through the corporate annual report, so the gap here is an access failure on 30 September 2026, not a jurisdiction that withholds officer data. Nationality is not disclosed and is recorded as Not disclosed: the Virginia annual report does not capture nationality, and nationality has not been inferred from any name, address or country field. No date of birth, no national identification number and no personal or residential address is published here; the stored rows carry only business-address and country fields, and those have not been reproduced as personal data.

Group Structure
Group structure of MPR ASSOCIATES, INC.
The provider’s corporate tree has two nodes. The top node is MPR ASSOCIATES, INC. itself, and it carries a Virginia identifier, 0614006, that is different from the identifier F1095134 held in the company record — the provider therefore holds two conflicting Virginia identifiers for the same company, and the register was unreachable on 30 September 2026 to settle which belongs to this entity. Beneath it sits one node, NuSource, LLC, with the Virginia identifier 5108356. That relationship is not verified. MPR’s own history describes NuSource LLC as a joint venture through which the firm provides the manufacture and certification of specialty nuclear-grade equipment; a joint venture is not a subsidiary, and no ownership or voting percentage is published for it. The company’s publications also refer to CH·IV International, an LNG venture, in the past tense and describe it inconsistently as both a joint venture and a former subsidiary, so it is not presented here as a current relationship. No parent company is recorded and none was found.
Data availability
Not public, and no verified relationship was located. There is no Exhibit 21 equivalent for this entity and there cannot be one: Exhibit 21 is an SEC filing requirement, and a search of EDGAR on 30 September 2026 returned no company matching the name, so MPR ASSOCIATES, INC. files no subsidiary list with any securities regulator. Virginia’s corporate annual report under Code of Virginia § 13.1-775 records the principal office, registered agent, directors, principal officers and authorised shares, and does not record parent or subsidiary relationships at all. The absence of a filed group structure is a disclosure limit in this jurisdiction and is not evidence that the company is independent, has no parent, or has no subsidiaries.

Frequently Asked Questions
What does MPR ASSOCIATES, INC. do?
MPR ASSOCIATES, INC. is an engineering and management consulting firm with its principal office at 320 King Street, Suite 400, Alexandria, Virginia, and further offices in East Lyme, Connecticut; Burlington, Massachusetts; and Salt Lake City, Utah. Federal contract records place almost all of its prime-contract work under NAICS 541330, Engineering Services. The US Nuclear Regulatory Commission inspected its Alexandria quality assurance programme from 6 to 10 March 2023; the NRC letter of 13 April 2023 describes the inspected scope as safety-related engineering and design services, software development, commercial-grade dedication services and Basler excitation systems and associated components for US nuclear power plants.
Who owns MPR ASSOCIATES, INC.?
Not disclosed. Two separate points apply. The data provider supplied no shareholder rows at all for this company, and independently Virginia does not publish shareholder identities: the annual report required by Code of Virginia section 13.1-775 gives the principal office, registered agent, directors, principal officers and the aggregate number of authorised shares, but not the names of shareholders. This is a disclosure limit, not evidence that the company has no shareholders.
Who is MPR ASSOCIATES, INC.'s UBO (Ultimate Beneficial Owner)?
Not publicly disclosed. The United States operates no public beneficial-ownership register; beneficial ownership information reported to the Financial Crimes Enforcement Network is held in a non-public system, and Virginia's corporate filings do not record beneficial owners. No ultimate beneficial owner of MPR ASSOCIATES, INC. can be stated from public sources, and none is asserted here. The absence reflects what the jurisdiction publishes, not the ownership of the company.
What is MPR ASSOCIATES, INC.'s company registration number?
MPR ASSOCIATES, INC.'s registration number is F1095134, filed with Virginia State Corporation Commission in United States. Its current status on the register is active.
Is MPR ASSOCIATES, INC. still an active company?
MPR ASSOCIATES, INC.'s status on Virginia State Corporation Commission is listed as active.
What is MPR ASSOCIATES, INC.'s registered address?
The registered address on file for MPR ASSOCIATES, INC. is United States.
What is MPR ASSOCIATES, INC.'s revenue?
No revenue figure is published. The company is privately held, files no accounts publicly, and Virginia's corporate annual report carries no financial statements. For scale in one area only, USAspending.gov records approximately USD 150.4 million of federal prime-contract obligations to MPR ASSOCIATES, INC. between 1 October 2015 and 29 September 2026. That is federal contract spend, not company revenue, and it covers only its US federal customers.
Is MPR ASSOCIATES, INC. listed on a stock exchange?
Not listed. A search of the SEC EDGAR company database on 30 September 2026 returned no company matching the name, so MPR ASSOCIATES, INC. has no ticker, no exchange listing and no periodic or proxy filings with the SEC.
Who are the officers/directors of MPR ASSOCIATES, INC.?
The provider holds five officer rows out of a stated twelve. Every row is flagged active, none carries an appointment or resignation date, and the addresses are mixed, including one Connecticut address that matches no published MPR office, so the vintage and provenance of the set cannot be established. The officers of record are those named on the company's Virginia annual report, which under Code of Virginia section 13.1-775 must list the directors and principal officers. That register refused connections on 30 September 2026, so no individual is named in this profile.
Does MPR ASSOCIATES, INC. have a parent company or subsidiaries?
No parent company is recorded and no subsidiary is verified. The provider's two-node tree places NuSource, LLC beneath MPR ASSOCIATES, INC., but the company's own history describes NuSource LLC as a joint venture rather than a subsidiary, and no ownership percentage is published. The company is not an SEC registrant, so there is no Exhibit 21 subsidiary list for it, and Virginia's annual report does not record group relationships. The gap is a disclosure limit, not proof of independence.
Can Zavia monitor changes to MPR ASSOCIATES, INC.'s ownership over time?
This profile reflects a point-in-time snapshot from Virginia State Corporation Commission. Zavia's monitoring API can track changes to MPR ASSOCIATES, INC.'s registered shareholders, officers, and group structure going forward, flagging updates as they're filed rather than requiring a manual recheck.
Can I access MPR ASSOCIATES, INC.'s data through an API?
Yes. Zavia's API connects directly to official government ownership registries across 195 countries and territories, including United States, so records like MPR ASSOCIATES, INC.'s registration, shareholder, UBO, and group-structure data can be queried programmatically instead of viewed one page at a time.
Where does this company information come from, and how current is it?
This record is sourced directly from Virginia State Corporation Commission and was last synced on 29 September 2026.
