The risk factors in a 10-K are the section of a public company's annual report where it discloses the material factors that make an investment in the company speculative or risky. It appears as Item 1A of the Form 10-K, and its content is governed by Item 105 of Regulation S-K. The section is not a generic disclaimer; the rule requires it to be specific to the registrant and organized so that each risk stands on its own.

Item 105 sets the standard for what belongs in the section and how it must be presented.

"Where appropriate, provide under the caption “Risk Factors” a discussion of the material factors that make an investment in the registrant or offering speculative or risky. This discussion must be organized logically with relevant headings and each risk factor should be set forth under a subcaption that adequately describes the risk."— SEC Regulation S-K, Item 105 (17 CFR 229.105), source

The current text of Item 105 reflects a 2020 SEC amendment that tightened the section in three ways. It requires each risk to sit under a subcaption that describes the risk, so a reader can scan headings rather than wade through undifferentiated prose. It discourages generic risks that could apply to any company and, where they are included, directs them to a separate “General Risk Factors” caption at the end. And it requires a concise, bulleted or numbered summary of no more than two pages at the front when the full discussion runs longer than 15 pages. Item 105 also tells the company to concisely explain how each risk affects the registrant or the securities, rather than merely naming the risk.

Reading risk factors as disclosure, not prediction

Risk factors describe what could go wrong; they are not forecasts that the events will occur. Their evidentiary value lies in two places. First, the specific risks a company chooses to disclose, and the order and emphasis it gives them, reflect what management and counsel considered material enough to surface. Second, and often more telling, is what changes from year to year. Because the 10-K is filed annually, comparing this year's Item 1A against last year's shows which risks were added, expanded, or removed. A newly added risk factor — a fresh disclosure about a regulatory regime, a customer concentration, a supply dependency, or an unresolved investigation — is a dated signal that the company's own assessment of its exposures shifted.

It is worth being precise about what Item 1A is not. It is not a list of every conceivable hazard, and it is not a prediction that the disclosed events will happen. Item 105 calls for the material factors that make an investment speculative or risky, and it asks the company to explain how each risk affects the registrant or its securities rather than to estimate a probability. A risk factor that a regulatory change could harm results, for instance, is a statement that the exposure exists and is material if it materializes — not a forecast that the change will occur. Reading the section as a probability-weighted forecast misuses it; reading it as the company's own, rule-governed catalog of material exposures uses it as intended.

The placement of risk factors within the 10-K is itself prescribed. Item 1A sits early in the annual report, after the business description in Item 1, so that a reader encounters the company's material risks before the detailed financial discussion. Item 105 reinforces this for registration statements by requiring the risk-factor section to follow the prospectus summary immediately, and by capping the summary at two pages of concise, bulleted or numbered statements when the full discussion exceeds fifteen pages. The structural rules are not cosmetic: they exist so that the most material exposures are findable and scannable rather than buried.

The 2020 amendment that produced the current Item 105 text changed the disclosure standard in a way that rewards careful reading. By moving from a prior 'most significant factors' framing to a 'material factors' standard, by requiring descriptive subcaptions, and by quarantining generic risks under a 'General Risk Factors' heading, the rule pushed companies toward risks specific to the registrant and away from boilerplate that could apply to anyone. The practical consequence is that the subcaptions near the top of the section — the company-specific ones — carry the most information, while the General Risk Factors block at the end is, by the rule's own design, the part most likely to be standard-issue.

The highest-value analytical use of Item 1A is comparison over time. Because a 10-K is filed every year under the same line-item rule, two consecutive annual reports can be set side by side to see which risk factors were added, materially expanded, narrowed, or dropped. A newly added subcaption is a dated record that the company's own view of its exposures shifted — a fresh disclosure about a regulatory proceeding, a single large customer, a key-supplier dependency, or a pending matter. The rule does not require companies to flag the change, so the comparison is the reader's work; but because every 10-K is public on EDGAR under the issuer's CIK, the year-over-year diff of Item 1A is fully reconstructable from primary documents.

Item 105 deliberately steers companies away from boilerplate, but boilerplate persists, which is why the General Risk Factors caption matters: risks parked there are, by the rule's own framing, the ones that could apply to almost any issuer. The substantive read is in the company-specific subcaptions higher in the section. For a reader, Item 1A is the company's own catalog of material exposures, written under a rule that demands specificity, and each year's 10-K is public on EDGAR under the issuer's CIK — making the risk-factor section, and its year-over-year edits, the primary source behind any claim about how a company frames its own risks.
