How to Decode the Ownership Structure Table in an S-1: Founder and Investor Shareholding Analysis

The SEC’s December 2024 final rule on “Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure” — effective for annual reports filed after 15 September 2025 — has forced every issuer filing a Form S-1 to reassess how material insider ownership data is presented and verified. The ownership structure table, or “beneficial ownership table” in SEC parlance, is no longer a static snapshot of share counts. It is now the primary document used by the SEC’s Corporation Finance staff to cross-reference risk factors, related-party transaction disclosures, and control-person designations under Item 403 of Regulation S-K. For Hong Kong-based issuers pursuing a NYSE or NASDAQ listing, this table carries additional weight: it must reconcile Hong Kong’s SFO Part XV disclosure thresholds (5% for substantial shareholders) with the SEC’s 5% beneficial ownership trigger, often producing a table that shows 15-25 named holders where a comparable Hong Kong listing would show 5-8. Misalignment between the table and the issuer’s Hong Kong statutory register — a frequent finding in the SEC’s 2024 comment letter review — now triggers automatic deficiency letters that can delay an IPO by 8-12 weeks. Understanding how to read this table, and how to construct it for a dual-registration issuer, is the single most important due diligence step for any cross-border investor or sponsor.

The Anatomy of the Beneficial Ownership Table: What the SEC Actually Requires

The SEC’s disclosure framework for beneficial ownership in a Form S-1 is governed by Item 403 of Regulation S-K, which mandates a table listing every person known to the issuer to be the beneficial owner of more than 5% of any class of voting equity securities. The table must show the name and address of each beneficial owner, the amount and percentage of each class owned, and the nature of the beneficial ownership — sole voting power, shared voting power, sole dispositive power, or shared dispositive power.

The Three Categories of Beneficial Owners

The table must capture three distinct categories: directors and named executive officers (NEOs) as a group, all directors and executive officers as a group, and any 5% or greater beneficial owner who is not a director or officer. For Hong Kong issuers, the “group” disclosure triggers a specific structural challenge. Under Hong Kong’s Securities and Futures Ordinance (SFO) Part XV, interests held by a director’s spouse or minor children are attributed to the director only if the director has control or influence over those shares — a narrower attribution than the SEC’s Rule 13d-3, which attributes any shares held by a spouse in a joint account or through a family trust. The SEC’s 2023 Staff Legal Bulletin No. 14L (CF) clarified that a director’s spouse’s shares must be included in the “directors and officers as a group” line unless the issuer can demonstrate the spouse exercises independent voting and dispositive power. This distinction has caused at least 12 Hong Kong-based S-1 filings in 2024 to restate their group percentages upwards by 3-8 percentage points after SEC comment.

The Percentage Calculation: Treasury Shares and Warrants

The percentage ownership calculation must use the total number of shares of the class outstanding as of the most recent practicable date. For issuers with outstanding warrants, options, or convertible instruments, the table must show both the “percentage of outstanding shares” (using only shares actually outstanding) and the “percentage assuming conversion” (the fully diluted figure). The SEC’s Division of Corporation Finance, in its 2024 Compliance and Disclosure Interpretations (C&DIs), confirmed that warrants exercisable within 60 days must be included in the fully diluted percentage, even if the exercise price is above the current market price. For a Hong Kong issuer with a typical pre-IPO warrant structure — often issued to placement agents under a 5-year term with a 120% of IPO price strike — this 60-day rule means the table must include warrants that may never be exercised, artificially inflating the “control” percentage of the founding shareholder group. In the 2024 S-1 of a Shenzhen-based biotech issuer, the founder’s fully diluted ownership dropped from 62.3% to 48.9% after including 60-day exercisable warrants held by a Hong Kong-based private equity fund, triggering a re-evaluation of whether the founder still held “control” for purposes of the issuer’s corporate governance certification under NYSE Listed Company Manual Section 303A.

Decoding the Footnotes: Where the Real Information Lives

The footnotes to the beneficial ownership table are frequently more important than the table itself. The SEC requires that any material assumption, condition, or limitation on beneficial ownership be disclosed in a footnote. For Hong Kong issuers, the most common footnote disclosures involve share pledges, lock-up agreements, and voting agreements.

A footnote must disclose any shares pledged as collateral for a loan, and the name of the pledgee. This requirement stems from the SEC’s 2022 interpretive release on “Disclosure of Pledged Securities,” which noted that pledged shares are not beneficially owned by the pledgee unless the pledgee has the right to vote or dispose of the shares. However, the pledgor must still disclose the pledge as a material limitation on the pledgor’s beneficial ownership. For a Hong Kong-based issuer whose founder has pledged 40-60% of his holdings to a Hong Kong bank as collateral for a margin loan — a common structure given Hong Kong’s low-cost margin lending at HIBOR + 150 bps — the footnote must state the exact number of pledged shares, the name of the lending institution, and the terms under which the pledgee could acquire voting power. The SEC’s 2024 comment letter to a Cayman-incorporated, Hong Kong-headquartered education technology issuer required the issuer to disclose that the founder’s pledged shares (4.2 million ADSs, representing 34.7% of outstanding shares) were subject to a margin call at a 50% loan-to-value ratio, and that the lending bank had the right to vote the shares only after a default. This disclosure directly affected the issuer’s ability to rely on the “controlled company” exemption under NASDAQ Listing Rule 5615(c), as the SEC argued the pledge effectively transferred control to the bank.

Lock-Up Agreements and Their Impact on Beneficial Ownership

Lock-up agreements, typically 180 days for Hong Kong sponsors under the HKEX’s Practice Note 22 (for Main Board IPOs) or the SEC’s standard underwriting agreement, must be footnoted if they restrict the holder’s ability to sell or transfer shares. The SEC’s 2023 Staff Legal Bulletin No. 14M clarified that a lock-up agreement does not, by itself, remove the holder from the beneficial ownership table — the holder still has voting and dispositive power, subject to the lock-up restriction. However, the footnote must state the lock-up period, the number of shares subject to the lock-up, and any exceptions (e.g., transfers to family trusts, charitable organizations, or underwriters). For a Hong Kong issuer with a dual-class share structure — Class A shares with 1 vote per share and Class B shares with 10 votes per share — the lock-up footnote must also disclose whether the lock-up applies to both classes equally. In the 2024 S-1 of a Hong Kong-based fintech issuer, the founder’s Class B shares (representing 72.3% of voting power) were subject to a 180-day lock-up, but the Class A shares held by early investors were subject to a 90-day lock-up. The footnote disclosed this differential treatment, which the SEC used to question whether the founder’s voting power was effectively “locked” for the full 180-day period, potentially affecting the issuer’s classification as a “controlled company” under NYSE rules.

Cross-Border Reconciliation: The Hong Kong SFO vs. SEC Framework

For any issuer that has filed a Hong Kong prospectus under the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32) or has a statutory register under the SFO, the beneficial ownership table in the S-1 must be reconciled with the Hong Kong disclosures. This reconciliation is not optional — the SEC’s 2024 comment letter review found that 23% of Hong Kong-based S-1 filers had discrepancies between their S-1 table and their Hong Kong substantial shareholder register.

The 5% Threshold Difference

Under Hong Kong’s SFO Part XV, a person who holds 5% or more of the voting shares of a Hong Kong-listed company must file a disclosure. For an issuer incorporated in the Cayman Islands or Bermuda — the standard structure for a Hong Kong company listing in the US — there is no Hong Kong statutory register requirement unless the issuer also lists in Hong Kong. However, many Hong Kong-based issuers maintain a voluntary register of substantial shareholders for internal governance purposes. The SEC requires that any person who is a “substantial shareholder” under Hong Kong law must be disclosed in the S-1 table, even if that person holds less than 5% of the US-listed class. The SEC’s 2023 Staff Legal Bulletin No. 14N clarified that the “5%” threshold in the S-1 table refers to the US-listed class, not the issuer’s total outstanding shares. For a Hong Kong issuer with a dual-class structure where Class A shares (1 vote) trade on the NASDAQ and Class B shares (10 votes) are privately held, a holder of 4.9% of Class A shares but 0% of Class B shares would not appear in the S-1 table, even if that same holder owns 8% of the issuer’s total voting power. This technicality has been exploited by Hong Kong family offices to avoid disclosure, and the SEC has signaled in its 2024 Rulemaking Agenda that it intends to propose amendments to Item 403 to close this gap.

The “Group” Concept: Hong Kong vs. SEC

Hong Kong’s SFO defines “group” for disclosure purposes as two or more persons who have an agreement to act together in exercising voting power. The SEC’s Rule 13d-5(b) defines a “group” as two or more persons who agree to act together for the purpose of acquiring, holding, voting, or disposing of equity securities. The key difference is intent: the SEC requires an express or implied agreement, while Hong Kong’s SFO requires a formal agreement in writing. For a Hong Kong issuer where a founding family has an unwritten understanding to vote together — common in Hong Kong’s closely-held corporate culture — the SEC’s definition would treat them as a group, while Hong Kong’s SFO would not. The SEC’s 2024 comment letter to a Hong Kong-based consumer goods issuer required the issuer to treat the founder, his brother, and his brother-in-law as a group, even though they had no written voting agreement. The footnote disclosed that the three individuals had voted together in all shareholder meetings since the issuer’s incorporation in 2018, and that the SEC deemed this pattern sufficient to establish a group. The effect was to increase the “directors and officers as a group” line from 58.2% to 72.1%, triggering a re-evaluation of the issuer’s controlled company status.

Common Pitfalls in S-1 Ownership Tables for Hong Kong Issuers

The SEC’s comment letter database for 2024 reveals three recurring deficiencies in Hong Kong-based S-1 filings that directly relate to the beneficial ownership table.

Failure to Include Pre-IPO Convertible Instruments

Hong Kong issuers frequently issue convertible notes or SAFE (Simple Agreement for Future Equity) instruments to early-stage investors. Under SEC rules, any convertible instrument that is exercisable within 60 days must be included in the fully diluted ownership calculation. However, many Hong Kong issuers structure these instruments with a 90-day conversion period to avoid this requirement. The SEC has rejected this structuring in at least four 2024 comment letters, arguing that the conversion period is “artificially extended” and that the economic substance is a near-term conversion. The SEC’s 2024 C&DIs on Item 403 clarified that a conversion period of more than 60 days will be respected only if the issuer can demonstrate a bona fide business reason for the extended period. For a Hong Kong issuer with a pre-IPO convertible note that converts automatically upon a qualified IPO, the conversion period is typically 30 days post-IPO — well within the 60-day window. The footnote must disclose the conversion price, the number of shares issuable upon conversion, and the conversion triggers.

For a Hong Kong issuer entering the US market via a SPAC merger, the beneficial ownership table must include the SPAC sponsor’s shares and warrants. The SEC’s 2023 Staff Legal Bulletin No. 14O clarified that SPAC sponsor shares are considered “founder shares” and must be disclosed in the table, even if the sponsor has agreed to forfeit a portion of its shares upon the merger’s closing. The footnote must disclose the forfeiture percentage, the vesting conditions, and any anti-dilution protections. In the 2024 S-1 of a Hong Kong-based electric vehicle SPAC target, the sponsor’s 8.1 million founder shares (representing 20.0% of the post-merger company) were subject to a 50% forfeiture if the stock price did not reach USD 12.00 within 12 months of the merger. The SEC required the issuer to disclose this forfeiture condition in a footnote, and to present the ownership table both before and after the forfeiture event. The result was a table showing the sponsor with 20.0% ownership on the closing date and a pro-forma 10.0% ownership after 12 months, creating a material uncertainty for investors evaluating the sponsor’s incentives.

The “Control Person” Trap

The SEC defines a “control person” as any person who possesses, directly or indirectly, the power to direct or cause the direction of the management and policies of the issuer. This definition is broader than the SFO’s “controller” definition, which requires a 30% or greater voting interest. For a Hong Kong issuer where a single family holds 25-30% of the voting power, the SEC may still deem the family a control person if they have the practical ability to elect a majority of the board. The SEC’s 2024 comment letter to a Hong Kong-based real estate issuer required the issuer to classify the founder’s family as a control person, even though the family held only 28.4% of the voting power, because the family had nominated 5 of the 7 board members since incorporation. The footnote disclosed the family’s board nomination history and the informal agreement among family members to vote together. This classification triggered additional disclosure requirements under Item 404 of Regulation S-K (related-party transactions) and Item 407 (corporate governance), adding 15 pages to the S-1.

Actionable Takeaways

For any Hong Kong issuer filing a Form S-1 after 15 September 2025, the beneficial ownership table must reconcile the SEC’s Rule 13d-3 attribution standard with the SFO Part XV disclosure thresholds, and any discrepancy must be footnoted with a precise explanation of the difference in attribution methodology.
The “directors and officers as a group” line must include shares held by spouses and family trusts unless the issuer can demonstrate independent voting and dispositive power, as confirmed by the SEC’s 2023 Staff Legal Bulletin No. 14L.
Pre-IPO convertible instruments with a conversion period of 60 days or less must be included in the fully diluted ownership calculation, and any instrument with a conversion period exceeding 60 days must have a documented bona fide business reason to avoid SEC recharacterization.
For SPAC mergers, the ownership table must present post-merger ownership both before and after any sponsor forfeiture conditions, with the forfeiture trigger and percentage clearly footnoted.
The “control person” classification must be evaluated under the SEC’s broader definition, not Hong Kong’s SFO 30% threshold, and any informal voting arrangement among family members must be disclosed as a group under Rule 13d-5(b).
