Form 253G3 Files Dataset

The Form 253G3 Files Dataset is a curated EDGAR archive of every Form 253G3 filing — the dual-purpose offering-circular supplement filed under Rule 253(g)(3) of the Securities Act of 1933 by Regulation A issuers whose Form 1-A has already been qualified. Each record represents one accession-numbered submission and carries both the previously omitted pricing information (offering price, underwriting discount, proceeds) and substantive non-pricing amendments to the most recently filed offering circular. Filings are made by the issuer itself, identified by CIK, and must be submitted no later than two business days after the earlier of price determination or first use of the supplement after qualification. The dataset covers all Form 253G3 submissions on EDGAR from November 1, 2016 to the present, distributed as monthly ZIP containers carrying HTML, JSON, and PDF files for each filing.

Dataset Files

What This Dataset Contains

The dataset is the complete EDGAR-sourced corpus of Form 253G3 filings — offering-circular supplements used in qualified Regulation A offerings whenever a single updated circular both supplies information omitted under Rule 253(b) and reflects substantive changes to the most recently filed offering circular. Each filing is captured at the submission level, identified by its 18-digit SEC accession number, and packaged with both filing-level metadata and the underlying offering-circular documents.

Records are partitioned into monthly ZIP archives organized as <YYYY>/<YYYY-MM>.zip. Each monthly ZIP expands to a single YYYY-MM/ directory whose immediate children are accession-numbered filing folders, one per Form 253G3 submission accepted by EDGAR in that month. For each accession number, the dataset includes a metadata.json describing the filing together with all documents in the original EDGAR submission except image files. The earliest sample date is November 1, 2016 — Regulation A's modernized supplement architecture took effect on June 19, 2015, and the earliest 253G3 filings on EDGAR appear from late 2016 onward, so there is no pre-2015 paper equivalent to backfill. Documents inside each record are delivered as HTML (the SGML-wrapped offering-circular supplement and any companion text or HTML exhibits), JSON (the per-filing metadata.json), and PDF where the filer included one in the original submission.

Content Structure of a Single Record

What one record represents

One record in the Form 253G3 Files Dataset corresponds to a single Form 253G3 submission filed with EDGAR — that is, one offering circular supplement filed by a Regulation A issuer pursuant to Rule 253(g)(3) under the Securities Act of 1933. The unit of observation is the filing as identified by its 18-digit SEC accession number. On disk, a record is a folder named after that accession number with dashes removed; the folder contains a metadata.json describing the filing together with the primary offering-circular document and any other non-image documents that were part of the original EDGAR submission.

Container layout

The hierarchy is therefore:

          1
          YYYY/
        

          2
            YYYY-MM.zip
        

          3
              YYYY-MM/
        

          4
                <18-digit-accession-no-without-dashes>/
        

          5
                  metadata.json
        

          6
                  form253g3.htm           (or filer-chosen variant)
        

          7
                  <additional non-image documents, if any>
        

Folder names use the bare digit form of the accession number (for example 000149315225004088); the dashed form (0001493152-25-004088) appears only inside metadata.json and in EDGAR URLs. There is no nesting beyond the accession-numbered folder: every file belonging to a single 253G3 submission sits flat at that level.

What the underlying filing is

Form 253G3 is one of three offering-circular delivery variants used in qualified Regulation A offerings, alongside 253G1 and 253G2. The three are distinguished by what they carry:

• 253G1 — final offering circular as qualified, with no changes.
• 253G2 — offering circular containing only previously omitted pricing information.
• 253G3 — offering circular containing both previously omitted pricing information and substantive changes to the most recently filed offering circular.

A 253G3 must be filed no later than two business days after the earlier of (a) the determination of the offering price or (b) first use of the supplement following qualification of the underlying Form 1-A. The body of the filing is the full revised offering circular, headed by the Rule 253(g)(3) legend, the issuer name, and the 024- series Regulation A file number assigned at the Form 1-A stage. Because 253G3 is a prospectus-style narrative filing rather than a periodic financial report, it carries no XBRL exhibits and no series-and-classes data.

The metadata.json record

metadata.json is a single JSON object describing the filing at the submission level. Its fields are:

• formType — the literal string 253G3.
• accessionNo — the dashed 18-digit accession number (for example 0001493152-25-004088), the canonical SEC identifier for the filing.
• id — a 32-character hexadecimal dataset-internal record identifier.
• filedAt — ISO-8601 timestamp with timezone offset, recording the EDGAR acceptance time.
• description — the short EDGAR filing description, typically Form 253G3 or a close variant.
• linkToFilingDetails — URL to the primary HTML document on EDGAR.
• linkToTxt — URL to the full-submission .txt aggregate on EDGAR.
• linkToHtml — URL to the EDGAR filing-index page.
• linkToXbrl — empty string for this form type; Form 253G3 has no XBRL associated data.
• documentFormatFiles — ordered array of document descriptors mirroring the EDGAR submission manifest. Each descriptor carries sequence (the SGML sequence number), size (bytes, as a string), documentUrl (canonical EDGAR URL), type (for example 253G3 or GRAPHIC), and optionally description. The trailing entry typically points to the complete-submission .txt aggregate and carries a blank sequence and type.
• dataFiles — empty array; no XBRL or data exhibits exist for 253G3.
• seriesAndClassesContractsInformation — empty array for 253G3.
• entities — array of party records, one per filer/issuer associated with the submission. Each entity object carries companyName, cik, the Regulation A fileNo (for example 024-12517), formType, act ("33" for Securities Act filings), irsNo, fiscalYearEnd, stateOfIncorporation, sic (industry code with the HTML-encoded label), filmNo (EDGAR film number assigned at acceptance), and tickers (string array, often empty for unlisted Regulation A issuers).

documentFormatFiles is the bridge between the metadata and the on-disk files: every non-image document listed there appears as a file alongside metadata.json, while GRAPHIC entries and the complete-submission .txt aggregate remain accessible only through their EDGAR URLs.

The primary 253G3 document

The primary document is the offering-circular supplement itself, delivered as an HTML document inside EDGAR's SGML envelope. The wrapper has the canonical structure:

          1
          <DOCUMENT>
        

          2
          <TYPE>253G3
        

          3
          <SEQUENCE>1
        

          4
          <FILENAME>form253g3.htm
        

          5
          <TEXT>
        

          6
          <HTML>...</HTML>
        

          7
          </TEXT>
        

          8
          </DOCUMENT>
        

The <DOCUMENT>, <TYPE>, <SEQUENCE>, <FILENAME>, and <TEXT> tags are EDGAR-specific SGML markers and must be stripped before standards-compliant HTML parsers will treat the body as well-formed. The filename varies by filer (form253g3.htm, offering_circular.htm, issuer-named variants); downstream code should locate the primary file via the first documentFormatFiles entry rather than assuming a fixed name.

Inside the <TEXT> block, the HTML body carries the full text of the Regulation A offering circular. Typical content layers, in the order they usually appear, are:

• A cover legend identifying the filing as Filed Pursuant to Rule 253(g)(3) together with the 024- series Regulation A file number assigned to the qualified Form 1-A.
• An issuer identification block with the company name and state of incorporation, followed by an offering summary table giving the title and class of securities offered, amount offered, offering price per share or unit, gross and net proceeds, selling-agent commissions, and any selling-stockholder allocation.
• A table of contents.
• A summary of the offering and the issuer's business.
• A risk-factors section, restated or revised relative to the prior offering circular.
• A use-of-proceeds discussion reflecting the now-determined pricing.
• A dilution table where applicable.
• Business and management's discussion and analysis sections, frequently updated for the substantive changes that distinguish a 253G3 from a 253G2.
• A description of the securities being offered, covering dividend, voting, conversion, redemption, transfer, and liquidation rights.
• Plan of distribution, including selling-agent or broker-dealer arrangements, escrow arrangements where applicable, and subscription procedures.
• Management, executive compensation, security ownership, and related-party transaction disclosures.
• Selected financial information and, where included inline, audited or unaudited financial statements with notes.
• Legal matters, experts, and where-you-can-find-more-information sections.
• An index to financial statements where financial statements are reproduced or referenced.
• A signature block executed by the issuer, typically by an executive officer.

The narrative is heavily tabular in the cover page, offering summary, capitalization, dilution, and selling-stockholder disclosures, and predominantly prose in risk factors, business, MD&A, and securities-description sections. Image references inside the HTML (logos, charts, signature images) appear as <img> tags whose src attributes resolve against the EDGAR archive rather than against files inside the dataset record.

Included content

A record reliably includes:

• the filing-level metadata in metadata.json, including all identifiers, timestamps, EDGAR links, the entities table, and the document manifest;
• the primary 253G3 SGML-wrapped HTML document containing the full offering-circular supplement;
• any additional text or HTML documents that were part of the original EDGAR submission (where present), preserved under their original filenames.

Excluded or externally-referenced content

The dataset deliberately omits image files. GRAPHIC entries listed in documentFormatFiles (typically JPEGs and GIFs corresponding to logos, signature images, and inline figures) remain accessible only via their EDGAR URLs. The complete-submission .txt aggregate that EDGAR builds by concatenating all submission documents is referenced through linkToTxt and the trailing documentFormatFiles entry, but is not bundled. The qualified Form 1-A offering statement that a 253G3 supplements is a separate filing under its own accession number; the 253G3 record references it implicitly through the Regulation A fileNo carried on each entity but does not embed it. Sibling supplements under the same offering (253G1, 253G2, additional 253G3s, or any 253G4 post-qualification amendment) are likewise separate accession numbers.

Interpretation and extraction notes

Several nuances matter when working with these records:

• The entities array can contain more than one party when co-issuers or affiliated filers appear on the same submission. Each entity's tickers array is frequently empty, since many Regulation A issuers have no listed securities at the time of the filing.
• The Regulation A fileNo (the 024- series number on each entity) is the durable cross-filing key that links a 253G3 to its qualified Form 1-A and to any sibling 253G1 / 253G2 / 253G3 / 253G4 filings under the same offering. The accession number identifies a single submission; the fileNo identifies the offering across submissions.
• Because 253G3 is by definition an updated circular reflecting both pricing and substantive changes, identifying the substantive amendments generally requires comparison against the prior 253G1 or 253G2 (or an earlier 253G3) under the same fileNo. Those prior filings must be retrieved separately.
• The primary document's filename is filer-chosen. Pipelines should resolve it through documentFormatFiles[0] (or by matching type equal to 253G3) rather than relying on a hard-coded name.
• The SGML wrapper around the HTML body is not HTML and will confuse strict parsers; remove the leading <DOCUMENT>/<TYPE>/<SEQUENCE>/<FILENAME>/<TEXT> lines and the trailing </TEXT></DOCUMENT> lines before parsing.
• Image references inside the HTML resolve only against EDGAR; any rendering pipeline that expects co-located images must either fetch them from the EDGAR archive or accept missing images.
• The on-disk anatomy of a 253G3 record is uniform across the dataset's time range. The form, its SGML envelope, the HTML body convention, and the EDGAR submission manifest have not changed in structurally meaningful ways since Regulation A+ took practical effect under the 2015 amendments, so variation across filings is confined to the offering circular's narrative content rather than to the record's structural shape.

Who Files or Publishes This Dataset, and When

Who files the record

Each Form 253G3 record is filed by a Regulation A issuer whose offering statement on Form 1-A has already been qualified by the SEC's Division of Corporation Finance. The filer is the issuer itself, identified by its CIK on EDGAR. Underwriters, placement agents, transfer agents, and selling securityholders may be named in the supplement but are not filers.

The eligible filer population is limited by Rule 251 of Regulation A:

• Domestic issuers organized in, and with their principal place of business in, the United States or Canada.
• Issuers conducting either a Tier 1 offering (up to $20 million in any 12-month period, including up to $6 million for selling securityholders) or a Tier 2 offering (up to $75 million in any 12-month period, including up to $22.5 million for selling securityholders, after the 2021 amendments).
• Issuers whose Form 1-A has already been qualified. Form 253G3 cannot precede qualification.

Excluded from the form: SEC reporting companies that are not Tier 2 reporting issuers, blank check companies, registered investment companies and BDCs, oil-and-gas/mineral fractional-interest issuers, bad-actor disqualified issuers under Rule 262, and issuers whose qualification has been revoked under Rule 258. Foreign private issuers outside the U.S./Canada scope and issuers in registered Securities Act offerings use different channels (F-series or S-series registration with Rule 424(b) prospectus supplements).

When the record is created or required

Form 253G3 is event-driven, not periodic. It is the supplement channel established by Rule 253(g)(3) for the specific case where a single updated qualified offering circular does two things at once:

1. Supplies information permissibly omitted from the qualified offering circular under Rule 253(b), typically the public offering price, underwriting syndicate, discounts and commissions, and proceeds; and
2. Reflects substantive changes to the most recently filed offering circular beyond those pricing-related items, such as revised risk factors, updated use-of-proceeds, changes to the plan of distribution, modified securities descriptions, or refreshed financials.

When both conditions are present in the same supplement, the issuer must file on Form 253G3 no later than two business days after the earlier of:

• the date the offering price is determined, or
• the date of first use of the offering circular after qualification.

An issuer may file zero, one, or several Form 253G3 supplements over the life of a qualified offering, depending on how often a single updated circular meets both conditions. Corrections are filed as Form 253G3/A under the same triggering logic.

Regulatory framework

• Section 3(b) of the Securities Act of 1933 authorizes the Regulation A exemption. Section 3(b)(2), added by Title IV of the JOBS Act of 2012, produced Tier 2.
• Regulation A (17 CFR 230.251 through 230.263) sets eligibility, offering caps, qualification of Form 1-A, ongoing Tier 2 reporting (Forms 1-K, 1-SA, 1-U, Form 1-Z), and the post-qualification amendment regime.
• Rule 253(b) defines what may be omitted from the qualified circular. Rule 253(g) defines how supplemental versions must be filed.
• Rule 253(g)(3) is the operative provision for this form: dual-purpose supplements (Rule 253(b) omissions plus substantive changes), filed within two business days.

The Rule 253(g) supplement architecture took effect with the modernized Regulation A on June 19, 2015. The earliest Form 253G3 filings on EDGAR appear from late 2016 onward (the dataset begins November 1, 2016); there is no pre-2015 paper equivalent.

How This Dataset Differs From Similar Datasets or Filings

Form 253G3 sits inside a tightly defined Regulation A disclosure family. The most useful comparisons are its two sibling supplements (253G1 and 253G2), the parent offering statement (Form 1-A and its amendments), the Regulation A ongoing reporting trio (Form 1-K, Form 1-SA, Form 1-U), and the registered-offering analogue under Rule 424 (the 424B series).

Closest siblings: 253G1 vs 253G2 vs 253G3

All three are mutually exclusive supplements under Rule 253(g), filed by the same issuer population (Tier 1 and Tier 2 Regulation A) against an already qualified Form 1-A. The distinction is purely which subsection of Rule 253(g) applies, and that turns on what the supplement contains.

• 253G1 (Rule 253(g)(1)): a complete, self-contained offering circular. No previously omitted pricing, no later pricing add-on. Used when the issuer wants the circular on file in full form.
• 253G2 (Rule 253(g)(2)): a pricing-only supplement. Adds previously omitted pricing items (price, price ranges, underwriting discount) to a qualified circular. Cannot carry substantive changes.
• 253G3 (Rule 253(g)(3)): the dual-purpose supplement. Adds previously omitted pricing information and makes substantive changes to the last filed circular, in a single document, filed within two business days of the earlier of price determination or first post-qualification use.

The practical takeaways:

• 253G2 and 253G3 are not substitutes. Both deliver post-qualification pricing, but only 253G3 carries substantive disclosure changes alongside it. A clean post-qualification pricing time series requires combining 253G2 and 253G3.
• 253G1 is distinguished by the absence of staged pricing entirely; it is not part of the omitted-pricing mechanic at all.
• The three forms partition the Rule 253(g) universe; an issuer cannot choose between them stylistically, the content dictates the form.

If the substantive changes fundamentally alter the qualified offering statement, the issuer cannot use Rule 253(g) at all and must instead file a post-qualification amendment to Form 1-A and have it re-qualified before further sales. Rule 253(g)(3) covers the middle ground of substantive-but-not-fundamental updates that ride on the existing qualification.

Parent filing: Form 1-A, 1-A/A, 1-A POS

Form 1-A is the original offering statement (Parts I, II, III) that goes through SEC qualification. 1-A/A is a pre-qualification amendment. 1-A POS is a post-qualification amendment used when changes exceed what a Rule 253(g) supplement is permitted to carry.

• Scope: 1-A is the full disclosure document. 253G3 is a supplement layered on top of a qualified 1-A and replaces or amends specific sections rather than restating the whole circular.
• Timing: 1-A and 1-A/A are pre-qualification. 253G3 is strictly post-qualification.
• 1-A POS vs 253G3: the boundary is regulatory, not stylistic. When changes are fundamental enough to require re-qualification, the issuer must file 1-A POS; otherwise, substantive post-qualification changes ride in a 253G3. 1-A POS triggers SEC re-review; 253G3 does not.

Ongoing reporting: 1-K, 1-SA, 1-U

These are the post-offering reporting regime for Tier 2 Regulation A issuers (annual, semiannual, current). They share only the Regulation A ecosystem with 253G3.

• Function: ongoing financial and event-driven reporting, analogous to 10-K, 10-Q, and 8-K. Not offering-document machinery.
• Boundary: 253G3 updates the offering circular during a live offering. 1-K/1-SA/1-U report on the issuer after qualification regardless of offering activity. They complement 253G3 in a full issuer view but answer different questions.

Registered-offering analogue: Form 424B

Rule 424 supplements (424B1 through 424B8) are the registered public offering counterparts to Rule 253(g). They perform the same conceptual function under the registration regime rather than the Regulation A exemption.

• Closest functional analogues: 424B3 (substantive supplements) and 424B5 (pricing supplements) loosely mirror 253G2/253G3, though the rule structures and disclosure obligations differ.
• Filer population: Form 424B filers operate under S-1, S-3, F-1, or similar registration statements. 253G3 filers operate under Form 1-A. The populations are essentially disjoint.
• Substitutability: none. 424B cannot answer Regulation A questions, and 253G3 cannot answer registered-offering questions.

Boundary summary

The Form 253G3 Files Dataset captures one precise event: a post-qualification Regulation A supplement that simultaneously crystallizes previously omitted pricing and makes substantive changes to the last filed offering circular, filed within two business days of the triggering event. It is not the place for complete original circulars (1-A), pricing-only post-qualification updates (253G2), non-staged complete supplements (253G1), changes requiring re-qualification (1-A POS), ongoing reporting (1-K, 1-SA, 1-U), or registered-offering supplements (424B). Its natural analytical companions are the corresponding 1-A qualifications and the 253G2 pricing-only supplements; together they trace the full post-qualification disclosure path of a Regulation A offering.

Who Uses This Dataset

Form 253G3 captures the moment a Regulation A issuer locks in pricing and discloses substantive changes to a previously qualified offering circular. A narrow set of professions uses the dataset, each reading different fields of the metadata.json record and the supplement body.

Regulation A securities counsel

Exempt-offering lawyers benchmark how peers structure post-qualification supplements under Rule 253(g)(3). They read the revised offering price, share volume, use-of-proceeds language, dilution tables, plan-of-distribution updates, and newly inserted risk factors to calibrate what counts as a "substantive change" and to support comment-letter responses on related Form 1-A amendments.

Issuer-side capital-markets attorneys

Counsel advising operating-company issuers use 253G3 supplements to design pricing-amendment strategies. They pair metadata.json fields (filer CIK, accession number, filing date, period of report) with the supplement's pricing schedule and cap-table impact to build precedent banks and sector-specific 253G3 templates.

Placement-agent compliance teams

Broker-dealer compliance staff monitor repricings and amendments on offerings their firm distributes. They focus on the plan-of-distribution section, selling-agent compensation schedule, and disclosure changes that affect suitability and sales-literature consistency, supporting Reg BI supervisory records and re-vetting of marketing materials when a 253G3 lands.

Small-cap and emerging-growth analysts

Analysts covering micro-cap and pre-IPO issuers treat 253G3 as the definitive pricing trigger. They extract offering price, securities volume, implied valuation, and any new risk factors to update deal sheets, dilution scenarios, and watchlists keyed to Reg A pricing events.

Retail investor research platforms

Product teams running retail-facing screeners ingest metadata.json (issuer name, CIK, filing date, accession number) for indexing and parse the supplement for structured pricing, minimum investment, share counts, and use-of-proceeds bullets. The dataset feeds offering-detail pages, alerts, and historical pricing-change archives.

Private-market data aggregators

Vendors building exempt-offering databases use 253G3 to complete each Reg A deal record from 1-A qualification through 253G2/253G3 supplements to 1-K reporting. Accession-level metadata drives deduplication and linkage; parsed supplement fields populate offering-economics tables and placement-agent league tables.

Reg A+ researchers

Finance, law, and entrepreneurship researchers study Reg A+ uptake using filing-frequency time series, the mix of substantive versus pricing-only supplements, and the content of revised risk factors and use-of-proceeds disclosures. CIKs and filing dates from metadata.json anchor merges with broader EDGAR panels.

Small-cap origination bankers

Bankers originating Reg A transactions read price per share, total offering size, primary/secondary allocation, and changes to underwriting terms to build pitch books, comparable-deal tables, and pricing recommendations on whether to launch, reprice, or withdraw an offering.

Issuer finance and treasury teams

In-house finance staff at current and prospective Reg A issuers use the dataset for repricing precedent and disclosure language on use of proceeds and dilution. The supplement's revised economics inform board materials and the internal call on whether changes warrant a new qualification cycle or a 253(g)(3) supplement.

Regtech and data engineers

Engineers building Reg A pipelines consume metadata.json for schema-driven indexing (form type, CIK, filing date, accession, document list) and the HTML/PDF supplements for text extraction and pricing-field parsing. The bounded, complete corpus serves as a controlled benchmark for parser regression tests and extraction-accuracy evaluation on exempt-offering documents.

Specific Use Cases

The Form 253G3 Files Dataset is content dense: each record captures a Regulation A offering at the moment its issuer locks in pricing and amends substantive disclosure. The following workflows show how practitioners use the records in practice.

Building a complete post-qualification pricing series for a Regulation A offering

Analysts and private-market data vendors join 253G3 records to their 253G2 and 1-A counterparts via the 024- Regulation A fileNo carried in each entity record. Pulling the offering-summary table out of the supplement body yields offering price, share count, gross and net proceeds, and selling-agent commission for each pricing event, producing a per-offering price history that 253G2 alone cannot deliver because only 253G3 carries substantive amendments alongside pricing.

Diffing risk factors and use-of-proceeds language against the prior circular

Securities counsel and Reg A+ researchers retrieve the immediate predecessor (a 253G1, 253G2, or earlier 253G3 sharing the same fileNo) and run a section-level diff against the current 253G3's risk-factor and use-of-proceeds prose. The output supports comment-letter responses, peer benchmarking of what qualifies as a "substantive change" under Rule 253(g)(3), and academic studies of disclosure evolution during live offerings.

Monitoring repricings on offerings a broker-dealer distributes

Placement-agent compliance teams subscribe to new 253G3 accession numbers filtered by entity cik for issuers their firm has under engagement. When a record lands, they extract the plan-of-distribution section, selling-agent compensation schedule, and revised dilution table to re-vet marketing materials, refresh suitability files, and update Reg BI supervisory records within the two-business-day filing window.

Building precedent banks and 253G3 templates by industry

Issuer-side capital-markets attorneys group records by the entity sic code and stateOfIncorporation, then index the supplement bodies to assemble sector-specific precedent libraries. Typical retrievals return cover legends, offering-summary tables, dilution schedules, and plan-of-distribution clauses from comparable issuers, which counsel reuse when drafting a client's own 253(g)(3) supplement.

Retail-platform indexing and offering-detail pages

Product teams at retail research platforms ingest metadata.json for issuer name, CIK, filedAt, and accession number to drive search and alerting, then parse the supplement for offering price, minimum investment, share count, and use-of-proceeds bullets to populate offering-detail pages and historical pricing-change archives. The bounded corpus is small enough to backfill in a single pass.

Parser regression benchmark for exempt-offering pipelines

Regtech engineers use the dataset as a fixed evaluation set for offering-circular extractors. Because every record shares the same SGML envelope, documentFormatFiles[0] resolution pattern, and tabular cover-page conventions, the corpus exercises the awkward parts of EDGAR processing (SGML stripping, filer-chosen filenames, EDGAR-relative image references, multi-entity entities arrays) without volume noise, making it well suited to regression tests on field-level extraction accuracy.

Frequently Asked Questions

What form does this dataset cover?

The dataset covers Form 253G3, the offering-circular supplement filed under Rule 253(g)(3) of the Securities Act of 1933 by Regulation A issuers whose Form 1-A has already been qualified. Form 253G3 is the dual-purpose supplement that simultaneously supplies previously omitted pricing information and makes substantive changes to the most recently filed offering circular.

What does one record in this dataset represent?

One record represents a single Form 253G3 submission to EDGAR, identified by its 18-digit SEC accession number. On disk, it is a folder named after the accession number containing a metadata.json file describing the filing plus the primary offering-circular HTML document and any other non-image documents from the original EDGAR submission.

Who is required to file Form 253G3?

The filer is the Regulation A issuer itself, identified by CIK on EDGAR, whose Form 1-A has already been qualified by the SEC's Division of Corporation Finance. Eligible filers are Tier 1 or Tier 2 Regulation A issuers organized in and with their principal place of business in the United States or Canada. Underwriters, placement agents, transfer agents, and selling securityholders may be named in the supplement but are not filers.

When must Form 253G3 be filed?

Form 253G3 must be filed no later than two business days after the earlier of (a) the date the offering price is determined or (b) the date of first use of the offering circular after qualification of the underlying Form 1-A. It is event-driven, not periodic, and a single offering may produce zero, one, or several 253G3 supplements over its life.

What time period does the dataset cover?

The dataset covers all Form 253G3 filings submitted to EDGAR from November 1, 2016 through the present. The Rule 253(g) supplement architecture took effect with the modernized Regulation A on June 19, 2015, and there is no pre-2015 paper equivalent to backfill.

How does Form 253G3 differ from Form 253G2?

Both are post-qualification offering-circular supplements filed under Rule 253(g), but 253G2 is a pricing-only supplement that supplies previously omitted pricing items without substantive non-pricing changes, while 253G3 is the dual-purpose supplement that supplies previously omitted pricing and makes substantive changes to the last filed circular. They are not substitutes — a clean post-qualification pricing time series for a single offering generally requires combining both 253G2 and 253G3 records under the same Regulation A fileNo.

What file formats does the dataset use?

Records are distributed as monthly ZIP containers organized as <YYYY>/<YYYY-MM>.zip. Inside each accession-numbered folder, the dataset includes JSON (metadata.json), HTML (the SGML-wrapped offering-circular supplement and any companion text or HTML documents), and PDF where the filer included one in the original submission. Image files referenced by GRAPHIC entries in the EDGAR manifest are deliberately excluded and remain accessible only through their EDGAR URLs.
