Form 8-K: what triggers it, the item numbers and how to read one

A Form 8-K is a US public company's "current report": the filing it makes when something important happens between its scheduled quarterly and annual reports. A signed merger agreement, a new chief executive, a change of auditor, the results of a shareholder vote, an earnings release. The 10-K and 10-Q arrive on a calendar; the 8-K arrives when the event does, usually within four business days.

That timing makes the 8-K the fastest official record of corporate news. Press releases and headlines may come first, but the 8-K is the version the company signs and files with the Securities and Exchange Commission (SEC), with the legal liability that carries. This guide explains what triggers one, the item numbers that organize it, the difference between information that is "filed" and "furnished", and how to read one quickly, using every 8-K Apple Inc. filed from October 2025 to July 2026.

What a Form 8-K is

The SEC's periodic system has three layers. The annual report on Form 10-K is audited and complete. The quarterly 10-Q is reviewed, not audited, and shorter. Between them, the 8-K fills the gaps with event-driven disclosure, so investors don't wait up to three months to learn that the company has a new CFO or has agreed to buy a rival.

Every 8-K has the same skeleton: a cover page (company name, state of incorporation, the date of the earliest event reported), one or more item headings with a short narrative under each, a signature, and often exhibits. The item headings are the key. They are fixed by the form, so a company cannot invent its own; it picks the items that match what happened. On EDGAR, the SEC's filing system, the items are listed next to every 8-K in the filing index, which lets you see what a filing is about before you open it.

US domestic companies file 8-Ks. Foreign private issuers use a different form (6-K) for the same purpose, and the rules here don't apply to them.

The item numbers that matter

Form 8-K groups its items into nine sections. Sections 1–6 and 9 describe events that require a report; Sections 7 and 8 are voluntary. Section 6 is only for asset-backed securities. The items an equity investor meets most often:

A single 8-K can carry several items. An earnings 8-K almost always pairs Item 2.02 with Item 9.01, because the release is attached as an exhibit. A closed acquisition might combine 2.01, 2.03 (the borrowing that paid for it) and 9.01 (the target's financial statements).

Some items are rare and loud. Item 4.02, non-reliance, is among the most serious things a company can file: it says that previously published financial statements should no longer be relied on, usually ahead of a restatement. Item 4.01, a change of auditor, deserves a careful read too, because the filing must say whether there were disagreements with the departing firm.

The four-business-day deadline

General Instruction B.1 to Form 8-K sets the default: a report is due within four business days after the event. If the event falls on a weekend or a day the SEC is closed, the count starts on the next business day. A few items carry their own clocks:

• Item 1.05 (cybersecurity): four business days after the company determines the incident is material, not after it happens.
• Item 5.07 (votes): four business days from the day the meeting ended, with an amendment for final results if only preliminary counts were available.
• Item 7.01 and Regulation FD: when a company uses an 8-K to meet Regulation FD, the Regulation FD timing applies instead.
• Item 5.02 amendments: if pay terms for a new officer aren't settled at filing time, the company files an amendment (8-K/A) within four business days after they are.

In practice, large companies often file the same day or the next day, because the news has already gone out in a press release and the 8-K is the formal record.

Furnished versus filed

Most 8-K content is filed, which makes it subject to Section 18 of the Securities Exchange Act of 1934, the provision that creates liability for false or misleading statements in documents filed with the SEC. Two items work differently. Under General Instruction B.2, information reported under Item 2.02 (results of operations) or Item 7.01 (Regulation FD disclosure) is furnished: it is not deemed filed for Section 18 purposes unless the company says it is, and it is not automatically pulled into other registration documents by reference. Exhibits attached for those items count as furnished too, unless Item 9.01 says otherwise.

Why it matters to a reader:

• Earnings releases are furnished. That's why the release itself sits on the 8-K as an exhibit and the audited version of the annual numbers arrives later in the 10-K. Furnished doesn't mean unregulated: the general anti-fraud rules still apply, and non-GAAP figures in an Item 2.02 release must follow the SEC's reconciliation rules (see GAAP vs non-GAAP earnings: how adjusted numbers are built).
• Item 7.01 is the Regulation FD channel. A company that shares material information with analysts at a conference, or updates guidance mid-quarter, often furnishes the slides or the statement under 7.01 so everyone gets it at the same time.

Item 2.02 also has a scope limit worth knowing: it is triggered when a company publicly discloses material non-public information about a completed quarter or year. Results first disclosed in a 10-Q or 10-K don't need a separate 2.02 report.

Apple's 8-Ks, October 2025 to July 2026

Apple is a good example of a quiet 8-K filer. In the ten months after its fiscal 2025 year-end, it filed exactly eight:

• Four earnings 8-Ks (Items 2.02 and 9.01): October 30, 2025 (Q4 fiscal 2025), January 29, 2026, April 30, 2026 and July 30, 2026. Each attached the release as Exhibit 99.1. Each 10-Q followed a day later; the 10-K for fiscal 2025 followed on October 31, 2025.
• Three leadership 8-Ks (Item 5.02): December 5, 2025, a new general counsel to take over on March 1, 2026; January 2, 2026, a new principal accounting officer effective January 1; and April 20, 2026, the CEO transition, with Tim Cook moving to executive chair and John Ternus becoming CEO on September 1, 2026. An 8-K/A on September 1, 2026 then added the new pay arrangements, outside the window shown in the figure.
• One vote 8-K (Items 5.07 and 9.01): February 24, 2026, the results of the annual meeting held that day.

No 1.01, 2.01 or 4.0x items appear: Apple announced no material acquisition, no auditor change and no restatement in that stretch. A list like this is itself information. A company with frequent Item 2.03 debt filings, Item 3.02 private share sales or a sudden Item 4.01 is telling you something different.

How to read an 8-K in two minutes

1. Read the item numbers first. On EDGAR they are listed in the filing index. They tell you whether this is routine (2.02, 5.07) or unusual (4.02, 1.03, 3.01).
2. Find the event date on the cover page. Compare it with the filing date to see how quickly the company reported.
3. Read the narrative under each item. Item 5.02 filings are short; note whether a departure is a retirement, a resignation or a termination, and whether a successor is named.
4. Open the exhibits. Under Item 9.01, Exhibit 99.1 is usually the press release; Exhibit 10.x is a material contract; Exhibit 104 is the inline XBRL cover page data.
5. Check for amendments. An 8-K/A adds or corrects information. For Item 5.02 it often adds pay terms decided after the announcement.

Pitfalls

• The press release is not the whole filing. The release may spin the news; the item narrative and the attached agreements are the binding version.
• "Furnished" numbers are preliminary. The quarterly figures in an Item 2.02 release can be refined in the 10-Q. Compare them when the 10-Q arrives.
• Item 8.01 is voluntary and broad. Companies use it for everything from a dividend declaration to litigation news. Don't assume 8.01 means minor.
• Absence of an 8-K is not absence of news. Several items turn on the company's own materiality judgment, and the four-day window means an event can be public for days before the filing appears.
• Event date versus filing date. The cover page gives the date of the earliest event reported; the EDGAR index gives the filing date. Use the first when you line the news up against a price chart.

The 8-K and its neighbours

The SEC filings explained: 10-K, 10-Q, 8-K, proxy, 13F and more overview puts these in one calendar; Insider trading filings: Forms 3, 4 and 5 and how to read them covers Form 4 and 13F filings: what institutional holdings reports show and miss covers institutional holdings.

How Finabase does it

Finabase doesn't render 8-Ks, but its pages line up with them. The earnings calendar lists which companies report each day, from five days back to 20 days ahead; on report day, the earnings 8-K is the document behind the numbers. On a company's Earnings tab, each row shows the report date, the quarter it covers, the EPS estimate, reported EPS and the surprise. Apple's row for October 30, 2025 shows the September-quarter EPS of $1.85, the same figure as the Item 2.02 release that day. The "Next earnings" card shows the next expected date, which is when the next Item 2.02 8-K should appear on EDGAR.

For the full text, go to Apple's filing index on EDGAR and filter for form type 8-K. The items column tells you which events each one reports.

Frequently asked questions

What triggers a Form 8-K?

A Form 8-K is triggered by any event listed in the form's items, such as a material agreement, a completed acquisition, an earnings release, a change of auditor, an officer or director change, or the results of a shareholder vote. Companies may also file voluntarily under Items 7.01 and 8.01.

How long does a company have to file an 8-K?

Generally four business days after the event, under General Instruction B.1 to Form 8-K. A few items, such as cybersecurity incidents and Regulation FD disclosures, have their own timing rules.

What does "furnished, not filed" mean on an 8-K?

It means the information, typically an earnings release under Item 2.02 or a Regulation FD disclosure under Item 7.01, is not subject to Section 18 liability of the Exchange Act and is not automatically incorporated into other SEC filings. Anti-fraud rules still apply.

Which 8-K items are red flags?

Item 4.02 (non-reliance on past financial statements), Item 4.01 (auditor change), Item 3.01 (listing deficiency), Item 1.03 (bankruptcy) and Item 2.06 (material impairment) usually signal trouble worth reading in full. Context matters: an auditor change can be routine, but the filing must say whether there were disagreements.

Summary

The Form 8-K is the SEC's event-driven report: when something material happens, a US public company picks the matching numbered items and files within four business days in most cases. Item 2.02 carries the earnings release and, like Item 7.01, is furnished rather than filed. Item 5.02 reports leadership changes, Item 5.07 vote results, and Item 9.01 the exhibits. Apple's eight 8-Ks from October 2025 to July 2026, four earnings releases, three leadership changes and one vote, show what a routine pattern looks like, and make it easier to spot the rare items, such as 4.01, 4.02 or 3.01, that deserve a close read.
