FLINN SCIENTIFIC FOUNDATION

Shareholders of Flinn Scientific Foundation

Flinn Scientific Foundation has no shareholders. That is not a disclosure gap: it is structural. The Internal Revenue Service Exempt Organizations Business Master File extract for Illinois dated 28 September 2011 codes the organisation (employer identification number 31-1618963) with organization code 1, a corporation, and subsection code 03, exempt under section 501(c)(3). A not-for-profit corporation of that kind issues no share capital, so there is no equity for anyone to hold and nothing for a shareholder register to record. Whatever stood in place of a shareholder body — a voting membership, or a self-perpetuating governing body — is a matter for the organisation’s articles of incorporation and bylaws, and neither document was located on any public record reached for this profile.

One field in the IRS record is easy to misread as ownership. The foundation code is 15, which the IRS’s own information sheet for the extract defines as an organisation that receives a substantial part of its support from a governmental unit or the general public under section 170(b)(1)(A)(vi). That describes where the organisation’s money came from, not who owned it. Donors, contributors and grant recipients are not shareholders of Flinn Scientific Foundation and are not reported as such here.

The same code disposes of a related expectation. Because the IRS classified the organisation as publicly supported rather than as a private foundation (code 04), it was not a Form 990-PF filer, and its PF filing requirement code is 0. The Form 990-PF is the return that publishes a schedule of substantial contributors; no such schedule exists for this organisation, and a substantial contributor would in any event be a donor rather than an owner.

Ultimate beneficial ownership

Flinn Scientific Foundation has no ultimate beneficial owner in the ownership sense. There is no ownership interest for any person to hold directly or indirectly, so no ownership chain exists and no effective percentage is calculable at any level. No person is identified as a beneficial owner of this organisation in any source reached.

Nor would a federal beneficial-ownership filing exist. FinCEN’s beneficial ownership information page, read on 6 October 2026, states that on 11 August 2026 FinCEN issued a final rule, which “became effective on August 14, 2026”, under which all entities created in the United States and their beneficial owners are now exempt from the requirement to report beneficial ownership information under the Corporate Transparency Act. For a US-created entity there is therefore no beneficial-ownership report to be absent or out of date, and its absence is not a gap in the record.

Data availability

Shareholder and beneficial-ownership information for Flinn Scientific Foundation is not partial, restricted or not found; it is inapplicable, because the entity has no share capital. The IRS Business Master File, which is the only register that holds a record of this organisation, publishes no owner, member, holding or percentage column at all — its full published field list runs EIN, name, in-care-of name, address, group exemption number, subsection, affiliation, classification, ruling date, deductibility, foundation code, activity codes, organization code, status, tax period, asset and income codes, filing requirement codes, accounting period, asset, income and revenue amounts, taxonomy code and sort name. The Illinois Secretary of State’s own register could not be read from either network path used on 6 October 2026, so no statement is made about what that register publishes.

The baseline provider field for this page carries no shareholder rows. It holds a 410-byte template whose stated reason is that “If no shareholders are displayed, the company is likely a private entity exempt from public disclosure.” That reason is wrong for this record. This is not a private company declining to publish a list; it is a corporation with no share capital to divide.

Directors and officers of Flinn Scientific Foundation

No director, officer or trustee of Flinn Scientific Foundation is identified on any public record reached for this profile, and no name is published here. The baseline provider data for this page contains no officer rows at all, so none of the defects that affect officer feeds elsewhere in this dataset — a resigned person carried as current, an invented job title, a reproduced residential address — arises on this record. No officer card appears on the page, and no appointment or cessation date exists to report.

The organisation’s IRS record carries exactly one personal name, in the field the extract labels ICO. The IRS’s own information sheet for the extract defines that field as follows: “In Care Of Name is the person (officer, director, etc.) to whose attention any correspondence should be directed.” It is a correspondence designation. It states no office, no appointment date and no term, so it is not a public-record basis for naming anyone as an officer of Flinn Scientific Foundation, and the name has been withheld on that ground.

Data availability

The dataset that would ordinarily name a principal officer for an organisation of this size and filing category is the IRS Form 990-N (e-Postcard) bulk file, which publishes a principal officer’s name and address for each filing. That file covers tax years 2007 to 2025 across 1,547,535 filings and contains no filing for employer identification number 31-1618963. The absence is controlled: in the same session a positive control drawn from the same town and postcode — Friends of the Batavia Library, employer identification number 16-1732493, Batavia, Illinois 60510 — returned a 2025 filing carrying a principal officer name and address, and a nonsense employer identification number returned nothing, so the file discriminates and the employer identification number is the field that joins.

The IRS Form 990 series electronic-filing index was also searched. It covers tax years 2017 to 2026 across roughly 5.6 million filings and contains no filing for this employer identification number, against 72 filings by organisations with “Flinn” in their name as a positive control. For the organisation’s actual filing years no IRS filing index or filing image is retrievable at all: the index series does not reach back before tax year 2017, and the legacy Amazon S3 bucket of IRS Form 990 index files returns a NoSuchKey error for 2011, 2015 and 2018 alike.

Officer information for Flinn Scientific Foundation is best described as not found. Nationality is not disclosed, and could not be: the IRS Business Master File publishes no nationality, residence, occupation or date-of-birth field for any person, and no filing naming a person was located. Residence and nationality are separate data points from a correspondence address in any event, and neither has been inferred from one here.

Three registers that might have answered the question could not be read on 6 October 2026, from either of the two network paths used. The Illinois Secretary of State’s business entity search returned an Akamai “Access Denied” page. The Illinois Attorney General’s Charitable Trust Bureau public register, which is a separate register from the Secretary of State’s and whose own search form carries a federal employer identification number field, returned a byte-identical HTTP 403 for the subject, for a known-name control and for a nonsense string, so no statement is made from it in either direction. The Illinois General Assembly’s statute site did not complete a connection, so no statement is made about what Illinois law requires an organisation of this kind to file.

The baseline provider field for this page is a 397-byte template rather than data. It asserts that “Officer data is not available for this jurisdiction” and offers five reasons, of which two are plainly false on this record’s own dates: the organisation is not newly incorporated, and no first filing deadline is outstanding for an entity whose latest return on the IRS record was for the tax period ending December 2010. The remaining three reasons cannot be tested, because the Illinois register is unreachable.

Group structure of Flinn Scientific Foundation

No parent, subsidiary, sister company, branch or affiliate of Flinn Scientific Foundation is verified by anything reached for this profile, and here that is a positive finding from a register rather than a bare absence. The Internal Revenue Service Exempt Organizations Business Master File carries two fields that record group relationships: the group exemption number, which the IRS’s own information sheet describes as a four-digit internal number assigned to central or parent organisations holding group exemptions, and the affiliation code. On the extract for Illinois dated 28 September 2011 the organisation’s group exemption number is 0000 and its affiliation code is 3, which the same sheet defines as “Independent – This code is used if the organization is an independent organization or an independent auxiliary (i.e., not affiliated with a National, Regional, or Geographic grouping of organizations).” The IRS therefore recorded Flinn Scientific Foundation as independent: neither a subordinate under a group ruling, nor itself a central or parent organisation.

Verified corporate relationships

Data availability

A similarly named company exists and is not a relationship. The website and LinkedIn addresses stored on this record both point to Flinn Scientific, Inc., a Batavia commercial supplier of science-education products. Nothing reached establishes any corporate link between that company and this organisation. The two are separately identifiable: Ares Capital Corporation’s Form 10-Q for the quarter ended 31 March 2026, filed 28 April 2026, lists “Flinn Scientific, Inc. and WCI-Quantum Holdings, Inc.” in its consolidated schedules of investments, described as a “Distributor of instructional products, services and resources”, against first lien senior secured loans and Series A preferred stock with an initial acquisition date of August 2018 — while the phrase “Flinn Scientific Foundation” returns no documents at all in SEC full-text search, against 126 for “Flinn Scientific” and none for a nonsense phrase. A shared surname, a shared town and a provider field pointing at one of them make neither a parent, a subsidiary nor an affiliate of the other.

Corporate-linkage information for Flinn Scientific Foundation is best described as not found, with one qualification in the organisation’s favour: the IRS record positively states independence rather than merely omitting a parent.

The baseline provider field is not a corporate tree. It is a 266-byte template reading “No parent, subsidiary, or ownership linkage is currently available for this company. This most often means the company is small, operates as a single entity, or has no branches or international presence recorded in the source registry.” Its only other content is an identifier, 1190748005, which is the data provider’s own internal company key — it is also the digit string at the end of this page’s address — and not a registration number of any kind. The template’s third reason carries no information here, because no register that holds this organisation has a branch or international-presence field to record anything in.

No Legal Entity Identifier exists for this organisation. A single-token trailing-wildcard search of the Global LEI Index on the legal name returns two records, neither of them this organisation nor Flinn Scientific, Inc., and a search on the stored registration number C60133484 returns none against a positive control drawn from the same Illinois prefix series, which returns one, and a nonsense value, which returns none. Those controls prove that the search works; they do not prove coverage. The Global LEI Index holds only 5,664 records attributed to Illinois Business Services at the Office of the Secretary of State, so no absence there can establish that Illinois holds no such entity or no such relationship.

Two further observations on the stored identifier, offered as observations and not as conclusions. Among those 5,664 Illinois records the number formats are 5,452 bare eight-digit numbers and 83 numbers of the form C plus six digits, every one of which belongs to a limited partnership or limited liability limited partnership; C followed by eight digits does not occur once. Separately, the eight digits of C60133484, read as a bare Illinois number, would fall between two dated neighbours, 60048614 and 60193886, which were both created in 1998 — the year the stored incorporation date gives. The number is therefore series-consistent as to date and unmatched as to format, and it resolves nowhere.

Two registers that could have answered the question were unreachable on 6 October 2026 from both network paths used: the Illinois Secretary of State’s business entity search, which returned an Akamai “Access Denied” page, and the Illinois Attorney General’s Charitable Trust Bureau public register, whose data endpoint returned a byte-identical HTTP 403 for the subject, for a control and for a nonsense string alike.
