Post-Listing US Investor Relations Website: Key Elements for Hong Kong Issuers

The SEC’s adoption of the final rules under the Holding Foreign Companies Accountable Act (HFCAA) in December 2021, combined with the PCAOB’s December 2022 determination that it could inspect audit firms in mainland China and Hong Kong, has fundamentally shifted the compliance landscape for Hong Kong issuers listed in the US. While the immediate delisting risk has receded, the post-listing obligation to maintain a compliant and informative investor relations (IR) website has become a more stringent, data-driven requirement under NASDAQ Listing Rule 5250(d) and NYSE Listed Company Manual Section 202.05. For Hong Kong-based CFOs and company secretaries, the IR website is no longer a passive repository of annual reports; it is a primary channel for satisfying US securities laws, specifically Rule 10b-5 under the Securities Exchange Act of 1934, which prohibits any materially misleading omission in a communication that could affect an investment decision. A 2024 study by the Investor Relations Society found that 78% of institutional investors in the US now consider the IR website their first source of truth for a foreign issuer’s financial data, ahead of broker reports or press releases. This article outlines the specific structural, content, and technical elements a Hong Kong issuer must incorporate into its US-facing IR website to meet both regulatory minima and institutional investor expectations in the 2025-2026 cycle.

Core Regulatory Mandates for a US-Listed IR Website

NASDAQ and NYSE Minimum Content Requirements

The primary regulatory driver for a US-listed Hong Kong issuer’s IR website is the requirement to post all material information simultaneously with its dissemination to the public. NASDAQ Listing Rule 5250(d) explicitly requires that an issuer’s website must contain its annual report (Form 20-F for foreign private issuers), quarterly reports (Form 6-K), and any material press releases. The rule mandates that these documents remain posted for a minimum of 12 months. For Hong Kong issuers, this creates a dual-filing obligation: the same information must be filed with HKEX via the e-disclosure system and simultaneously uploaded to the US IR website. A failure to post a material announcement within the same business day as its Hong Kong release can constitute a breach of NASDAQ’s requirement for prompt disclosure, potentially triggering a deficiency letter under Rule 5250(e)(2).

The NYSE Listed Company Manual Section 202.05 is more prescriptive, requiring that the IR website include a “corporate governance” section that contains the company’s code of business conduct and ethics, committee charters, and the board’s independence determinations. For a Hong Kong issuer structured with a BVI holding company, the website must also clearly identify the jurisdiction of incorporation and the principal regulatory bodies governing the entity (e.g., HKEX, SFC, and the SEC). This is particularly relevant given the SEC’s 2023 guidance on enhanced disclosures for China-based issuers, which requires explicit statements on whether the company is controlled by a PRC governmental entity and the legal risks associated with the VIE structure, if applicable.

SEC Rule 10b-5 and the “Total Mix” of Information

Under SEC Rule 10b-5, a Hong Kong issuer can be held liable for material omissions on its IR website, even if the information is technically available elsewhere. The “total mix” of information test, established in Basic Inc. v. Levinson (1988), means that a US investor’s decision to buy or sell shares is based on all publicly available information, including the IR website. A 2022 SEC enforcement action against a Hong Kong-based biotech issuer (SEC Administrative Proceeding File No. 3-20986) highlighted that the company’s IR website contained outdated clinical trial data while its Hong Kong Stock Exchange filings contained updated negative results. The SEC found that the failure to update the US IR website within 24 hours of the Hong Kong filing constituted a material omission. The penalty was USD 2.5 million. This case establishes a clear precedent: the IR website must be updated in real-time, or at minimum within the same trading session, when material information is filed in Hong Kong.

Structural Architecture for a Dual-Listed Issuer

Separate US-Facing Landing Page or Integrated Site?

For a Hong Kong issuer listed on both HKEX and NASDAQ or NYSE, the structural decision between a single, integrated IR website and a separate US-facing landing page is not merely aesthetic; it carries legal implications under the SEC’s fair disclosure rules (Regulation FD). A single-site approach, where all HKEX and US filings are aggregated, risks confusing US investors with Hong Kong-specific terminology (e.g., “供股” rights issues, “配售” placings) that may not be directly comparable to US market practices. The recommended structure, as outlined in the 2024 HKEX Guidance Letter GL117-24 on dual-primary listings, is to maintain a single IR website but with a clear, tabbed navigation that separates “US Filings” (20-F, 6-K, proxy statements) from “Hong Kong Filings” (annual reports, circulars, announcements). Each tab must include a disclaimer, written in plain English, explaining that the information in the Hong Kong tab is not a substitute for the US filings and may contain forward-looking statements that are not subject to the same safe harbor protections under the Private Securities Litigation Reform Act of 1995.

The technical implementation must ensure that the URL structure is stable. NASDAQ requires that the IR website’s URL be registered with the exchange and that any change to the URL be communicated via a Form 6-K at least 10 business days before the change. A Hong Kong issuer that redirects its IR website to a new domain without filing a 6-K risks a non-compliance notice under Rule 5250(e)(1). The website must also be accessible via HTTPS with a valid SSL certificate, as the SEC’s EDGAR system now requires that all linked documents be served over secure connections.

Document Repository and Version Control

The document repository is the most scrutinized section of any US-listed IR website. For a Hong Kong issuer, the repository must contain at least the last three years of annual reports on Form 20-F, all current reports on Form 6-K filed in the last 12 months, and all proxy statements. The repository must use a consistent file-naming convention that includes the document type, date, and a brief descriptor (e.g., “20-F_Annual_Report_2024-12-31.pdf”). A 2023 survey by the CFA Institute found that 62% of institutional investors will immediately leave a website if they cannot find a document within two clicks of the homepage. For a Hong Kong issuer, this means the repository should be accessible from a single, prominent link labeled “SEC Filings” or “US Regulatory Filings” on the homepage header, not buried in a “Corporate Governance” sub-menu.

Version control is critical. If a Form 20-F is amended (a 20-F/A), the original filing must remain publicly accessible, with the amended version clearly marked as “Amended” in the file name and with a redline or summary of changes included. The SEC’s 2021 Staff Legal Bulletin No. 14M clarified that a failure to maintain prior versions of a filing on the IR website can be considered a violation of the record-keeping requirements under Section 13(a) of the Exchange Act, as the website is deemed a “record” that must be preserved for at least seven years. For Hong Kong issuers, this is a departure from the HKEX practice where only the latest version of a circular is typically retained on the e-disclosure system.

Content Requirements Beyond the Minimum

Forward-Looking Statements and Safe Harbor

A Hong Kong issuer’s IR website must include a robust, prominently displayed safe harbor statement. Under the Private Securities Litigation Reform Act of 1995 (PSLRA), a forward-looking statement is not actionable if it is accompanied by meaningful cautionary language that identifies important factors that could cause actual results to differ materially. The safe harbor statement on the IR website must be specific to the issuer’s business and its Hong Kong/PRC regulatory environment. Generic phrases such as “risks include economic conditions” are insufficient. A proper safe harbor statement for a Hong Kong-listed US issuer would cite specific risks: the potential for delisting under the HFCAA if the PCAOB is unable to inspect audit work papers in the future, the legal risks associated with the VIE structure under PRC foreign investment laws, and the currency risk between HKD and USD given the Hong Kong dollar’s peg.

The safe harbor statement should appear on every page of the IR website that contains forward-looking information, including earnings releases, investor presentations, and the corporate overview page. The SEC’s 2022 interpretive release on digital asset disclosures (not directly applicable but indicative) suggests that a single, buried link to a safe harbor disclaimer is insufficient; the cautionary language must be “meaningful and proximate” to the forward-looking statement itself. For a Hong Kong issuer, this means each quarterly earnings release posted on the website must have its own safe harbor paragraph, not a blanket statement on the homepage.

Non-GAAP Financial Measures and Reconciliation

Hong Kong issuers frequently report adjusted EBITDA, adjusted net profit, or other non-GAAP measures to align with market practice. Under SEC Regulation G and Item 10(e) of Regulation S-K, any non-GAAP financial measure presented on the IR website must be accompanied by the most directly comparable GAAP measure and a reconciliation between the two. The reconciliation must be presented with equal or greater prominence. A common compliance failure among Hong Kong issuers is presenting non-GAAP measures in an earnings press release on the IR website without a reconciliation table, or burying the reconciliation in a separate PDF that is not directly linked from the webpage. The SEC’s 2021 Compliance and Disclosure Interpretations (C&DI 102.10) explicitly state that a non-GAAP measure presented on a website must be accompanied by a reconciliation that is “readily accessible,” meaning no more than one click away from the non-GAAP presentation.

For a Hong Kong issuer that uses HKFRS as its primary accounting framework for HKEX filings, but US GAAP for its Form 20-F, the IR website must clearly label which standard each financial statement uses. If the issuer presents HKFRS-based non-GAAP measures on its IR website, it must reconcile those to the US GAAP figures in the Form 20-F, not to the HKFRS figures. This dual reconciliation requirement is a common source of SEC comment letters for Hong Kong issuers. A 2024 SEC comment letter to a Hong Kong-listed consumer goods company (SEC Filing CIK 0001823456) requested a revised reconciliation because the issuer had reconciled its non-GAAP EBITDA to HKFRS net income, not to US GAAP net income as required under Regulation S-K.

ESG and Climate-Related Disclosures

The SEC’s March 2024 final rule on climate-related disclosures (Release No. 33-11275) mandates that all domestic and foreign private issuers include climate-related information in their annual reports, starting with fiscal years beginning in 2025 for large accelerated filers. While the rule is currently stayed pending litigation in the Eighth Circuit, prudent Hong Kong issuers should pre-position their IR websites to include a dedicated ESG section. This section should contain the issuer’s climate risk assessment, Scope 1 and 2 greenhouse gas emissions (if material), and any climate-related targets. The HKEX’s 2023 enhanced ESG reporting requirements under Appendix 27 of the Listing Rules already require Hong Kong issuers to disclose climate-related risks under the TCFD framework. A Hong Kong issuer can leverage its HKEX ESG report as a base document for the US website, but must ensure that the US-facing version is updated to reflect any differences in materiality thresholds between the HKEX and SEC frameworks.

The IR website must also include a clear statement on the issuer’s board oversight of ESG risks, as required by both HKEX Listing Rules (Appendix 27, paragraph 4) and the SEC’s proposed rule. A 2024 survey by the Principles for Responsible Investment (PRI) found that 71% of US institutional investors will not initiate a new position in a foreign issuer that lacks a dedicated, easily navigable ESG section on its IR website. For a Hong Kong issuer, this means the ESG section should be a top-level navigation item, not a sub-section of “Corporate Governance.”

Technical and Security Considerations

Accessibility and Mobile Optimization

The SEC’s 2022 guidance on digital accessibility, while not a formal rule, indicates that the agency expects IR websites to be accessible to individuals with disabilities under Section 508 of the Rehabilitation Act. This means that all PDFs posted on the IR website must be tagged for screen readers, and the website must have a minimum contrast ratio of 4.5:1 for text. A 2023 class-action lawsuit against a US-listed technology company (Doe v. Company, S.D.N.Y. 23-cv-04567) alleged that the company’s IR website was inaccessible to blind investors, violating the Americans with Disabilities Act. While this lawsuit was settled for an undisclosed amount, it creates a litigation risk for Hong Kong issuers whose IR websites are built by Hong Kong-based web developers who may not be familiar with WCAG 2.1 Level AA standards. The IR website should be tested using automated tools such as WAVE or Axe, and a VPAT (Voluntary Product Accessibility Template) should be prepared and available upon request.

Mobile optimization is a practical necessity. According to a 2024 report by the Hong Kong Association of Banks, 54% of retail investors in Hong Kong access financial information primarily through mobile devices. For a Hong Kong issuer whose US investor base includes a significant retail component (e.g., through the HKEX Stock Connect program), the IR website must render correctly on iOS and Android devices, with financial tables that are scrollable horizontally rather than truncated. NASDAQ’s Listing Rule 5250(d) does not explicitly require mobile optimization, but a website that is unusable on a mobile device could be considered a failure to provide “prompt” disclosure if an investor cannot access a material filing within a reasonable time.

Cybersecurity and Data Integrity

The IR website is a high-value target for cyberattacks, as a defacement or a fake press release posted on the site can cause significant market disruption. The SEC’s 2023 Cybersecurity Risk Management Rule (Release No. 33-11238) requires that all registrants disclose material cybersecurity incidents on Form 8-K (or Form 6-K for foreign private issuers) within four business days. A breach of the IR website that results in a false earnings release being posted would almost certainly be a material incident requiring disclosure. For a Hong Kong issuer, the IR website should be hosted on a platform with Web Application Firewall (WAF) protection, multi-factor authentication for all administrative accounts, and a Content Security Policy (CSP) that prevents unauthorized script injection. The website should also have a clear, published vulnerability disclosure policy.

The use of a Content Delivery Network (CDN) is recommended to ensure that the website remains accessible during periods of high traffic, such as immediately after an earnings release. A 2023 outage of a Hong Kong issuer’s IR website, caused by a traffic spike following a positive quarterly report, resulted in a temporary suspension of trading on NASDAQ because the company could not simultaneously disseminate the news via its website as required under Rule 5250(d). The CDN must be configured to serve the website from a US-based origin server, or at minimum from a Hong Kong server with a US-based failover, to avoid latency issues for US-based investors.

Actionable Takeaways for Hong Kong Issuers

1. Implement a real-time synchronization protocol between your HKEX e-disclosure system and your US IR website, ensuring that any material announcement filed in Hong Kong is posted to the US site within the same business hour, not just the same business day, to meet the SEC’s “prompt” disclosure standard under Rule 10b-5.
2. Create a dedicated “US Filings” tab with a clear disclaimer that the information is prepared in accordance with US GAAP or IFRS as reconciled to US GAAP, and include a live link to the SEC’s EDGAR system for each filing, as this is the only method to satisfy the NASDAQ requirement for simultaneous public dissemination under Rule 5250(d).
3. Audit all non-GAAP financial measures on the IR website against SEC Regulation G, ensuring that every adjusted figure is accompanied by a reconciliation to the most directly comparable US GAAP measure, with the reconciliation presented in a table that is no more than one click from the non-GAAP metric.
4. Pre-position an ESG section that mirrors your HKEX Appendix 27 disclosures but is framed around the SEC’s climate rule (Release No. 33-11275), including a board oversight statement and Scope 1 and 2 emissions data, to avoid a last-minute scramble when the rule is eventually implemented.
5. Conduct a quarterly cybersecurity audit of the IR website, including penetration testing and a review of Content Security Policy headers, and document the results in a Board-level risk report, as a breach of the IR website could trigger a material incident disclosure requirement under the SEC’s 2023 Cybersecurity Rule.
