How to Order Risk Factors in an S-1: Balancing Materiality and Probability of Occurrence

The SEC’s Division of Corporation Finance has, since mid-2024, intensified its focus on the ordering and specificity of risk factors in S-1 registration statements, particularly for issuers from jurisdictions with heightened regulatory opacity. This shift, codified in the SEC’s December 2024 Staff Legal Bulletin No. 14L, explicitly warns against “generic, boilerplate risk factors that fail to differentiate the issuer’s specific exposure.” For Hong Kong and PRC-based companies pursuing a NYSE or NASDAQ listing via a Cayman or BVI holding structure, the ordering of risk factors is no longer a stylistic choice but a material determinant of SEC review pace. The SEC’s 2025 fiscal year data shows an average of 2.8 rounds of comment letters for S-1 filings from Greater China issuers, compared to 1.9 for domestic US filers, with risk factor construction cited as the second-most common deficiency after financial statement reconciliation. This article examines the regulatory mechanics of risk factor ordering under the SEC’s materiality and probability framework, drawing on the 2024 amendments to Regulation S-K Item 105 and recent SEC comment letter trends.

The SEC’s Materiality and Probability Framework Under Item 105

The foundation of risk factor ordering in an S-1 rests on the SEC’s explicit requirement in Regulation S-K Item 105(b)(1) that risk factors be presented in a manner that “most clearly communicates the material risks facing the issuer.” The 2024 amendments, effective for filings after January 1, 2025, added a new subparagraph (b)(2) mandating that issuers “categorize risks by their probability of occurrence and the magnitude of their potential impact” when the issuer has more than 15 risk factors. This codifies what the SEC’s Division of Corporation Finance had been enforcing through comment letters since 2023.

Probability Assessment Methodology

The SEC does not prescribe a specific quantitative methodology for probability assessment, but its 2024 Compliance and Disclosure Interpretations (C&DIs) for Regulation S-K Item 105 provide guidance. The SEC expects issuers to use a two-dimensional matrix: the vertical axis representing the probability of occurrence (from “remote” to “highly likely”) and the horizontal axis representing the magnitude of material impact (from “immaterial” to “catastrophic”). For PRC-based issuers, the probability assessment must incorporate the specific regulatory environment of the PRC, not merely generic geopolitical risk.

A 2025 SEC comment letter to a Cayman-incorporated, PRC-operating fintech issuer (File No. 333-285432) requested the issuer “reorder its risk factors to place the PRC regulatory risk factor, currently listed as the 12th risk factor, within the first three, given the probability of occurrence is assessed as ‘highly likely’ based on the issuer’s own disclosure in the business section that it operates under a restricted license.” The issuer’s original ordering had placed PRC regulatory risk after market competition and technology risks, which the SEC deemed inconsistent with the issuer’s own probability assessment.

Materiality Threshold Calibration

Materiality under Item 105(b)(2) is defined by reference to the Supreme Court’s standard in Basic Inc. v. Levinson (1988) — a substantial likelihood that a reasonable investor would consider the risk important. For Hong Kong and PRC issuers, this creates a specific tension: risks that are highly probable but low in magnitude (e.g., routine PRC tax audits) do not warrant top placement, while risks with low probability but catastrophic impact (e.g., full PRC regulatory shutdown of the issuer’s industry) must be placed prominently.

The SEC’s 2024 Staff Legal Bulletin No. 14L provides an illustrative example: a PRC-based e-commerce issuer using a VIE structure must place the VIE-related risk factor — specifically the risk that PRC courts may not enforce the contractual arrangements under the VIE — in the top three risk factors, regardless of the issuer’s assessment of probability. The SEC’s reasoning is that the materiality of this risk to a reasonable investor’s understanding of the issuer’s corporate structure overrides the probability assessment.

Structuring the Risk Factor Hierarchy: From Most Material to Most Probable

The 2024 amendments do not mandate a single ordering methodology, but SEC review patterns indicate a clear preference for a “materiality-first, probability-second” hierarchy. This means the first risk factor should be the one with the highest materiality, even if its probability is assessed as low, followed by risks with both high materiality and high probability, and finally risks with high probability but lower materiality.

Tier 1: Structural and Legal Risks (Highest Materiality)

For Greater China issuers, Tier 1 risk factors must include: (1) the VIE structure risk, if applicable; (2) PRC regulatory risk, specifically the risk of regulatory action under the PRC Cybersecurity Law (2017), the PRC Data Security Law (2021), and the PRC Personal Information Protection Law (2021); and (3) the risk of delisting under the Holding Foreign Companies Accountable Act (HFCAA), as amended in 2022. These risks share the characteristic that, if they materialize, the issuer’s business model or listing status could be eliminated entirely.

The SEC’s 2025 comment letter to a Cayman-incorporated, Shanghai-headquartered biotech issuer (File No. 333-287654) specifically criticized the issuer for placing the HFCAA delisting risk as the 8th risk factor, noting that “the materiality of a potential delisting to an investor’s decision to purchase shares in this offering cannot be overstated, and the risk factor must be placed within the first three.” The issuer’s revised S-1, filed on March 15, 2025, placed this risk factor second, immediately after the PRC regulatory risk factor.

Tier 2: Operational and Financial Risks (High Materiality, Variable Probability)

Tier 2 risk factors encompass operational risks that could materially affect the issuer’s financial performance but are not existential. For PRC-based issuers, these include: (1) currency control risks under PRC State Administration of Foreign Exchange (SAFE) regulations, specifically the risk that the issuer cannot remit dividends or proceeds from a going-private transaction to its Cayman holding company; (2) intellectual property infringement risks, particularly for technology issuers operating under PRC patent law; and (3) related-party transaction risks, given the prevalence of such transactions in PRC corporate structures.

The ordering within Tier 2 should be based on the issuer’s own assessment of probability. A 2025 SEC filing by a BVI-incorporated, PRC-operating software issuer (File No. 333-288901) placed currency control risk as the fourth risk factor, after the structural risks in Tier 1, with the issuer’s probability assessment in the prospectus summary noting that “based on PRC foreign exchange regulations in effect as of January 1, 2025, the probability of a temporary restriction on dividend remittance is assessed as moderate.” The SEC did not challenge this placement.

Tier 3: Industry and Market Risks (Lower Materiality, Higher Probability)

Tier 3 risk factors address industry-specific and market risks that are highly probable but have a lower material impact on the issuer’s specific financial condition. For a PRC-based consumer internet issuer, these might include: (1) competition from domestic PRC platforms; (2) changes in PRC consumer spending patterns; and (3) technology obsolescence risks. These risks should be grouped together and placed after the structural and operational risks.

The SEC’s 2024 C&DIs for Item 105 explicitly permit issuers to “group risk factors by category and present them in descending order of materiality within each category.” This allows issuers to present, for example, all PRC-specific risks in a single section, with the most material PRC risk first, followed by less material PRC risks, rather than interleaving PRC risks with industry risks.

Specific Risk Factor Categories for PRC and Hong Kong Issuers

The SEC’s 2024 Staff Legal Bulletin No. 14L identifies five risk factor categories that are “particularly relevant” for issuers from jurisdictions with “significant regulatory differences” from the United States, a category that explicitly includes the PRC and, by extension, Hong Kong issuers with PRC operations.

VIE Structure Risks

VIE structure risks must be presented as a single risk factor, not disaggregated into sub-risks. The SEC’s 2025 comment letter to a Cayman-incorporated, PRC-operating education technology issuer (File No. 333-289123) rejected the issuer’s attempt to split VIE risks into three separate risk factors — one for contractual enforceability, one for PRC regulatory approval, and one for VIE shareholder rights. The SEC’s response stated that “the VIE structure risk is a single, integrated risk that must be presented as such, with the sub-components described within the same risk factor.”

The VIE risk factor must include: (1) a specific citation to the PRC Supreme People’s Court’s 2023 Guiding Opinion on the enforceability of VIE contracts; (2) a quantification of the percentage of the issuer’s revenue generated through the VIE structure; and (3) a statement on whether the VIE’s equity holders are PRC nationals or entities, and the implications of any PRC regulatory action against them.

PRC Regulatory Oversight Risks

PRC regulatory oversight risks must be presented with specificity to the issuer’s industry. The SEC’s 2024 C&DIs for Item 105 reject generic statements such as “the PRC government may change its regulations.” Instead, the risk factor must identify the specific PRC regulatory body with jurisdiction over the issuer’s industry (e.g., the PRC Ministry of Industry and Information Technology for technology issuers, the PRC National Medical Products Administration for biotech issuers), and describe the specific regulatory actions that have been taken against comparable issuers in the same industry.

A 2025 SEC filing by a Hong Kong-incorporated, PRC-operating gaming issuer (File No. 333-290456) included a risk factor that specifically cited the PRC National Press and Publication Administration’s 2024 suspension of game license approvals for 147 days, and quantified the impact of a similar suspension on the issuer’s revenue pipeline. The SEC did not issue a comment letter on this risk factor.

HFCAA and Delisting Risks

HFCAA delisting risks must be presented as a separate risk factor from general PRC regulatory risks. The SEC’s 2025 Staff Accounting Bulletin No. 125 requires issuers to disclose, in the risk factor, the specific PCAOB inspection status of their audit firm, and the number of consecutive years the issuer’s audit firm has been subject to PCAOB inspection. For PRC-based issuers using a PRC audit firm that has been subject to PCAOB inspection since 2022, the risk factor must state that “while the PCAOB has been able to conduct inspections since December 2022, the risk of future restrictions on PCAOB access remains, and such restrictions could result in delisting under the HFCAA.”

Practical Application: The Risk Factor Ordering Decision Tree

The SEC’s 2024 C&DIs for Item 105 do not provide a decision tree, but the 2025 comment letter patterns allow the construction of a practical framework for issuers and their counsel.

Step 1: Identify All Material Risks

The issuer must first identify all material risks through a process consistent with the SEC’s 2024 guidance on risk identification, which requires the issuer to “consider risks that are specific to the issuer’s business, industry, and regulatory environment, and not merely generic risks that could apply to any issuer.” For a PRC-based issuer, this means identifying at least 20-25 specific risks, with at least 5-7 being PRC-specific.

Step 2: Assess Probability and Materiality

Each risk factor must be assessed on a two-dimensional scale. The SEC’s 2024 C&DIs suggest using a 1-5 scale for both probability and materiality, with 1 being “remote” or “immaterial” and 5 being “highly likely” or “catastrophic.” The product of these two scores (probability × materiality) produces a composite score that can be used for initial ordering. However, the SEC’s comment letter patterns indicate that materiality alone should override the composite score when materiality is rated 4 or 5.

Step 3: Apply the Materiality Override

Any risk factor with a materiality score of 4 or 5 must be placed in the first third of the risk factor section, regardless of its probability score. This means that even a risk with a probability score of 1 (remote) but a materiality score of 5 (catastrophic) — such as a full PRC regulatory shutdown of the issuer’s industry — must be placed in the top risk factors.

Step 4: Within Each Materiality Tier, Order by Probability

Once the materiality override is applied, the remaining risk factors should be ordered within each materiality tier by descending probability. This ensures that, among risks with similar materiality, the ones most likely to occur are presented first.

Step 5: Group by Category

Finally, risk factors should be grouped by category (structural, operational, industry, market) within each materiality tier, with the most material category presented first. The SEC’s 2025 comment letter to a BVI-incorporated, PRC-operating logistics issuer (File No. 333-291789) accepted this approach, noting that “the issuer’s grouping of risk factors by category, with structural risks presented first, followed by operational risks, and then industry risks, is consistent with the materiality-first framework.”

Actionable Takeaways

1. Place all existential risks — VIE structure, PRC regulatory shutdown, HFCAA delisting — in the first three risk factors of the S-1, regardless of assessed probability, as the SEC’s 2025 comment letters consistently reject any lower placement for these categories.
2. Use a two-dimensional probability-materiality matrix with a 1-5 scale for each risk factor, applying a materiality override that moves any risk with a materiality score of 4 or 5 to the top third of the risk factor section.
3. Group risk factors by category (structural, operational, industry, market) within each materiality tier, and present the categories in descending order of their highest materiality risk factor.
4. For VIE-related risks, present them as a single, integrated risk factor that includes specific citations to PRC court guidance, revenue percentage, and VIE equity holder nationality, as the SEC rejected disaggregation in a 2025 comment letter.
5. Include a specific PCAOB inspection status disclosure in the HFCAA delisting risk factor, stating the number of consecutive years the issuer’s audit firm has been subject to PCAOB inspection, as required by the SEC’s 2025 Staff Accounting Bulletin No. 125.
