SEC Filing Analysis (10-K, 10-Q, 8-K)
Updated July 21, 2026
Examining public company filings for revenue, risk factors, competitive mentions, and strategic commentary.
Also known as: EDGAR filing analysis, SEC EDGAR monitoring, Public filings analysis, Regulatory filings analysis, 10-K analysis, 8-K monitoring
SEC filing analysis is the practice of reading a U.S. public company's mandatory regulatory disclosures, namely the annual 10-K, the quarterly 10-Q, and the event-driven 8-K, to extract revenue and financial detail, stated risk factors, named competitors, and management's own strategic commentary. Because these forms are legally binding and audited or reviewed, they are a different class of source than a press release or a landing page: the company is on the hook for what it says, so the disclosures tend to be candid about threats, dependencies, and where the business is soft.
All three forms are required under the Securities Exchange Act of 1934, which established periodic disclosure for public companies, and they are filed electronically with the SEC through EDGAR. EDGAR has carried filings since 1994 and offered full-text search since 2001, indexing new submissions within roughly a minute, which is what makes large-scale, keyword-driven monitoring of competitor filings practical rather than a manual archive dig.
The analysis itself is used across finance and competitive intelligence. Equity analysts read filings to model earnings; CI teams read them to see how rivals describe their own markets, whom they name as competition in Item 1 and Item 1A of the 10-K, and what material events an 8-K discloses within days of the trigger. The forms are also a formal research input: an academic method exists for quantifying competitive rivalry directly from 10-K text, evidence that the filings are treated as structured data, not just narrative.
The three forms and what each one carries
The 10-K is the audited annual baseline, typically 100 to 300 pages. Its competitively useful sections are Item 1 (Business), where a company describes its markets and often names competitors; Item 1A (Risk Factors), where it lists the threats it takes seriously; and Item 7 (Management's Discussion and Analysis), where leadership narrates the numbers. Large accelerated filers file it within 60 days of fiscal year end, accelerated filers within 75, and other filers within 90.
The 10-Q is the quarterly update against that baseline: unaudited but reviewed by independent accountants, roughly 30 to 60 pages, filed within 40 or 45 days of quarter end. Only three appear per fiscal year, because the fourth quarter rolls into the 10-K. The 8-K is the current report for material events: acquisitions, executive departures, bankruptcy, major contracts, restatements, cybersecurity incidents. It must generally be filed within four business days of the triggering event, which makes it the fastest-moving of the three and often the first documentary confirmation of a strategic move.
How competitive intelligence teams read filings
CI use of filings has two steps that are easy to conflate. Discovery is finding which filings matter: EDGAR full-text search, or a third-party alert tool, surfaces every new document that names a competitor, a market, or a keyword. Analysis is the read-and-interpret step: pulling the risk factors, decoding the MD&A narrative, and noting how a rival frames its own competitive set.
The highest-signal targets are consistent. Item 1A risk factors reveal what a competitor is defensive about, and changes to that list year over year often signal a shift in strategy before any announcement does. Named competitors in Item 1 show who a company thinks it is fighting, which is not always who you would assume. MD&A language around segment performance, pricing, and demand tells you where growth is coming from. An 8-K, read the week it lands, can confirm a funding event, an executive change, or an acquisition while the market is still reacting.
10-K vs. the shareholder annual report and adjacent filings
A 10-K is not the same document as a company's glossy annual report to shareholders. The 10-K is the SEC compliance filing, standardized and legally binding; the annual report is a shareholder communication piece, often heavy on design and narrative. Some companies combine them into a single '10-K wrap,' but the two serve different audiences and should not be treated as interchangeable when you want the rigorous version.
Other filings sit nearby and are sometimes lumped into 'SEC filings' loosely. The proxy statement (DEF 14A) covers executive compensation, board matters, and shareholder votes, which is useful but not one of the three forms in this term. An S-1 is the registration statement filed around an IPO, a one-time lifecycle document rather than a recurring report. Keeping these straight matters, because each answers a different question and carries a different level of financial assurance. The 10-Q figures are reviewed, not audited, so quarter-to-quarter comparisons should account for that lighter standard.

Frequently Asked Questions
What is the difference between a 10-K, 10-Q, and 8-K?
The 10-K is the comprehensive, audited annual report filed once a year. The 10-Q is a shorter, unaudited but accountant-reviewed quarterly update filed three times a year. The 8-K is a current report triggered by a specific material event, such as an acquisition, executive change, or restatement, and filed within about four business days of it. They complement each other: annual baseline, quarterly progress, and real-time events.
Is a 10-Q audited?
No. A 10-Q is reviewed by an independent accountant but not fully audited, so its figures carry less assurance than the audited numbers in a 10-K. That distinction matters when comparing quarters: a reviewed statement follows a lighter standard than an audit, and management has more latitude in a condensed quarterly MD&A than in the full annual discussion.
What section of a 10-K discusses competitors?
Two sections most directly. Item 1 (Business) describes the company's markets and frequently names specific competitors or characterizes the competitive landscape. Item 1A (Risk Factors) lists the threats the company takes seriously, which often includes competitive pressure, pricing, and new entrants. Reading how those two sections change year over year is a common way to detect a shift in a rival's strategy or self-perception.
Where can I find a company's SEC filings for free?
On EDGAR, the SEC's electronic filing system, which is free and public. It has hosted filings since 1994 and added full-text search in 2001, then indexes new submissions within about a minute of arrival. That speed and coverage let you set keyword alerts across all filers, for example every filing that mentions a specific competitor, not just search one company's own documents.
Do private companies have to file 10-Ks?
Sometimes. Filing obligations depend on size and shareholder count, not just being listed on an exchange. Companies with more than $10 million in assets and a large enough base of equity holders of record are generally required to register and file periodic reports under the Securities Exchange Act of 1934, even if their shares do not trade on a public exchange. Most small private companies have no such requirement.
