CarMax Auto Owner Trust 2026-4 Files 8-K Filing on EDGAR

An 8-K filing is the “current report” that companies and other registrants submit to the U.S. Securities and Exchange Commission to disclose events that investors may want to know about between regular quarterly and annual reports. On Oct. 21, 2026, CarMax Auto Owner Trust 2026-4 filed one on EDGAR, the SEC’s public database.

Key takeaways

• CarMax Auto Owner Trust 2026-4 filed an 8-K on Oct. 21, 2026 (accession number 0001193125-26-427486). EDGAR shows it was posted at 11:46 a.m. Eastern.
• The report lists Item 8.01 (Other Events) and Item 9.01 (Financial Statements and Exhibits). The filing package is about 2 MB.
• Two registration-related filings also appeared the same morning: an S-1/A from PBT Land & Minerals, Inc. and an F-1 from Sensing4D AI Ltd.
• These are routine disclosure documents. Their appearance on EDGAR is not a recommendation or a signal about any security’s value.

What happened

The filer is CarMax Auto Owner Trust 2026-4, an entity registered under its own EDGAR identifier. By convention, trusts with names like this are special-purpose vehicles that hold pools of auto loans and issue asset-backed securities to investors. The “2026-4” label typically identifies a particular securitization series.

The 8-K lists two items. Item 8.01 is a catch-all for events a registrant chooses to disclose that do not fit another category. Item 9.01 tells readers that financial statements or exhibits are attached. In asset-backed deals, those exhibits are commonly the transaction documents or related agreements, though readers should open the filing itself to see what was submitted.

The 2 MB size suggests a substantial exhibit package rather than a short cover note. The filing index on EDGAR is the place to find the full list of attached documents.

How it works

Most operating companies file 8-Ks within four business days of a triggering event, such as a leadership change, an acquisition, or a material agreement. Issuers of asset-backed securities use the same form for a different purpose. They often file one around the time a deal is priced or closed, so the underlying agreements become part of the public record.

Item 8.01 is flexible. A registrant can use it to put information on the record that it considers important but that no other item covers. Item 9.01 is the attachment mechanism. It points readers to the exhibits, which often hold the substance of the report.

For investors and analysts, the practical steps are simple. Open the filing index, read the main document, and then review each exhibit. The cover page and item list show the form’s category, and the exhibits show the details.

Other SEC filings today

The same morning brought two registration-stage documents. Both are part of the path a company follows when it plans to sell shares to the public.

PBT Land & Minerals, Inc. (S-1/A). An S-1/A is an amended registration statement. The “/A” shows that the company is revising an S-1 it filed earlier, usually in response to SEC staff comments or to update its disclosure. The amendment was filed at 6:21 a.m. Eastern and is about 260 KB. An amendment alone does not mean an offering has been priced or approved.

Sensing4D AI Ltd (F-1). An F-1 filing is the registration form for non-U.S. companies that want to offer securities in the United States. This one was posted at 6:19 a.m. Eastern and is about 18 MB, which is large and typical of a first full registration document with financial statements and risk disclosures. Filing an F-1 starts the review process. It does not mean the securities have been sold or that the SEC has cleared them.

FAQ

Does an 8-K from a trust mean something went wrong? No. For a securitization trust, an 8-K is often a routine way to file deal documents. Read the exhibits for context.

Does an S-1/A mean an IPO is imminent? Not by itself. Amendments are common while the SEC reviews a registration statement. Pricing and timing are separate steps.

Is an F-1 the same as an S-1? They serve the same purpose, registering a public offering. The F-1 is for eligible foreign private issuers, and the S-1 is for domestic filers.

What should readers watch next? Watch for further amendments, any pricing or effectiveness notices, and follow-up 8-Ks. Each new filing will appear on EDGAR under the same filer name.
