The risk-factor section is the part of a filing where a company is required to argue against itself. Regulation S-K, the SEC's set of disclosure requirements for non-financial-statement content, governs it in Item 105 (codified at 17 CFR 229.105). The rule requires a registrant to provide, where appropriate and under the caption "Risk Factors," a discussion of the material factors that make an investment in the registrant or offering speculative or risky. The discussion must be organized logically with relevant headings, and each risk factor must be set forth under a subcaption that adequately describes the risk. For an autonomous-vehicle developer, whose entire thesis rests on a capability that is still being proven, Item 105 is the provision that compels a candid, itemized account of what could go wrong.

The 2020 amendments to Item 105 sharpened the rule in ways that matter for reading it. The Commission moved the standard from "most significant" factors to "material" factors, required organization under relevant headings, and pushed back on boilerplate: the presentation of risks that could apply generically to any registrant is discouraged, and any generic risks that are presented must be disclosed at the end under the caption "General Risk Factors." The rule also requires a two-page summary at the front if the risk-factor discussion runs longer than 15 pages. The combined effect is that an AV company's risk section is supposed to be registrant-specific, not a recycled list, and the subcaptions themselves become a map of what management considers material.

How an AV company applies Item 105

Tesla, Inc. (TSLA) illustrates the standard in its 2025 Form 10-K, where it ties a discrete risk to its self-driving program: it states that if its autonomous driving solutions do not develop as the company expects, its business, prospects, financial condition and operating results may be harmed. That sentence does exactly what Item 105 (b) requires, concisely explaining how a specific risk affects the registrant, rather than leaving "autonomy is uncertain" as an unstated assumption. Read across an AV filing, the Item 105 subcaptions typically enumerate the material strands of self-driving risk: technological development and timing, regulatory and permitting exposure, safety and liability from accidents, competition, and the capital required to reach commercial scale. Each is supposed to stand under its own heading and explain its own effect.

Because the rule pushes against generic language, the subcaptions are where the analytical signal sits. A risk factor written specifically, naming the registrant's program, its dependencies, and the consequence to its business, carries more information than a generic caution that could appear in any company's filing. Item 105's instruction to relegate generic risks to a "General Risk Factors" bucket at the end is, in effect, a sorting mechanism: the registrant-specific material risks come first and are the ones management is asserting are most relevant to the autonomy story. For a reader mapping what an AV company itself believes could derail its roadmap, the ordered, captioned list is the most direct available statement.

The shift from “most significant” to “material” factors is worth understanding because it changed the inclusion test. Materiality is the long-standing securities-law threshold keyed to whether there is a substantial likelihood that a reasonable investor would consider the information important; tying the risk-factor standard to materiality aligns it with that broader disclosure principle and discourages the kitchen-sink lists that had grown common. Paired with the requirement to relegate generic risks to a clearly labeled “General Risk Factors” section and the two-page summary for discussions longer than 15 pages, the amendments push registrants toward shorter, more specific, better-organized disclosure. For an autonomous-vehicle company, that means the risk section should read as a tailored account of self-driving-specific exposure rather than a recycled compendium, and where it does not, the boilerplate itself is a signal.

Reading the section for what it admits

Three reading habits make Item 105 disclosure useful. First, read the subcaptions as a table of contents of management's own material concerns; their specificity (or vagueness) is itself information. Second, watch for the "how it affects us" clause the rule requires, because a risk that names a concrete consequence (delay, recall, loss of permit, inability to fund development) is more substantive than one that merely flags general uncertainty. Third, track changes period over period: a new or expanded AV risk factor, or one that moves out of the generic bucket into the registrant-specific section, reflects a shift in what the company now treats as material. None of this is investment advice; it is how to read a defined disclosure requirement for exactly what it compels the company to state, the material factors that make the investment speculative or risky, in the company's own words.

A final reading habit ties the section back to the rest of the filing. Item 105 risk factors should be consistent with what the business section describes and what the MD&A and financial statements show; a self-driving risk that is described as material in the risk-factor section but absent from the surrounding disclosure, or vice versa, is a discrepancy worth noticing. The strongest signal is coherence, the risk factors, the strategy, and the numbers telling the same story about where the autonomy program stands.

The durable point is that Item 105 is not a disclaimer section but a regulated disclosure with a specific standard: material, registrant-specific factors, each under a descriptive subcaption, each explained for its effect, with generic risks segregated at the end. For autonomous-vehicle companies, it is where the speculative nature of the self-driving bet is required to appear in writing, which is exactly why it is worth reading closely.
