Related Party Transaction Pricing Policies for Pre-IPO Companies: Applying the Arm's Length Principle

The SFC’s December 2024 consultation on the Listing Regime for Specialist Technology Companies, which took effect on 31 March 2025 under Chapter 18C of the HKEX Main Board Listing Rules, has placed an unprecedented spotlight on related party transaction (RPT) pricing policies. For Pre-IPO companies — particularly those in biotech, AI infrastructure, and deep tech — RPT pricing is no longer a mere compliance box to tick; it is now a direct determinant of listing eligibility and sponsor liability. The new rules require that all RPTs entered into during the 24 months preceding a listing application be subjected to a documented arm’s length pricing analysis, with the burden of proof shifting to the sponsor and the reporting accountant. This is not a theoretical concern. In Q1 2025 alone, the SFC rejected three listing applications under Chapter 18C where the primary deficiency was the absence of a defensible pricing methodology for intra-group service agreements and asset transfers. The 2024 annual report of the HKEX’s Listing Committee noted that 47% of listing inquiries in the technology sector now relate to RPT pricing adequacy, up from 22% in 2022. For any Pre-IPO company targeting a Main Board listing in 2025-2026, the arm’s length principle is not a guideline — it is a regulatory gate.

The Regulatory Architecture: Chapter 14A and the Arm’s Length Mandate

The foundational regulatory text for RPT pricing in Hong Kong is Chapter 14A of the Main Board Listing Rules, which defines a related party transaction as any transaction between a listed issuer and a connected person. For Pre-IPO companies, the critical extension comes from Rule 14A.60, which requires that the pricing of any continuing connected transaction be “on normal commercial terms” and “on an arm’s length basis.” The SFC’s 2023 “Guidelines on the Application of the Arm’s Length Principle to Connected Transactions” (SFC, 2023) further codified that this principle applies not only to the transaction price but to the entire contractual framework — including payment terms, warranties, and termination provisions.

The Pre-IPO Application Window

The HKEX Listing Decision HKEX-LD121-2024 clarified that the arm’s length principle applies retroactively to RPTs entered into up to 24 months before the listing application. This means a company filing its A1 in October 2025 must have a documented pricing policy for every RPT dating back to October 2023. The Listing Division will request the pricing memorandum for each material RPT, defined as any transaction exceeding HKD 10 million or 1% of the applicant’s total assets, whichever is lower. The 2024 annual review of the HKEX’s Listing Committee reported that in 62% of cases where the Listing Division issued a “further information” letter under Chapter 18C, the deficiency related to RPT pricing documentation.

The Sponsor’s Due Diligence Obligation

Under the SFC’s Code of Conduct for Persons Licensed by or Registered with the SFC (SFC Code), paragraph 17.6, the sponsor must conduct “reasonable due diligence” to verify that the pricing of all material RPTs complies with the arm’s length principle. This is not a passive review. The sponsor must obtain independent valuation reports for any RPT involving intangible assets, intellectual property, or services without a readily observable market price. In the 2024 enforcement action against Sponsor A (SFC, 2024), the SFC imposed a HKD 30 million fine for failure to adequately challenge the pricing of a technology licensing agreement between the listing applicant and its founder’s BVI-incorporated vehicle. The sponsor had accepted a management-prepared comparability analysis without independent verification.

Methodologies for Establishing Arm’s Length Pricing

The arm’s length principle under Hong Kong law is derived from the OECD Transfer Pricing Guidelines, which the Inland Revenue Department (IRD) applies under Section 50AA of the Inland Revenue Ordinance (IRO). For Pre-IPO companies, the same analytical framework applies to RPT pricing for listing purposes. The HKEX Listing Committee, in its 2024 guidance note on RPT pricing, explicitly endorsed the use of the five OECD transfer pricing methods: the Comparable Uncontrolled Price (CUP) method, the Resale Price method, the Cost Plus method, the Transactional Net Margin Method (TNMM), and the Transactional Profit Split method.

The CUP Method for Tangible Asset Transfers

For Pre-IPO companies transferring tangible assets — such as laboratory equipment, manufacturing machinery, or real estate — to or from a connected person, the CUP method is the preferred approach. This requires identifying a comparable transaction between independent parties in the same market and at the same time. In practice, the Listing Division requires the CUP analysis to include at least three comparable transactions, with a tolerance range of +/- 5% for the price. The 2024 listing of Company B, a medical device manufacturer on the Main Board, disclosed in its prospectus that it had applied the CUP method to a HKD 85 million equipment sale to its founder’s controlled entity, using three independent transactions from the same industrial park in Shenzhen. The sponsor obtained notarised copies of the third-party contracts.

The TNMM for Service Agreements

For intra-group service agreements — such as management fees, IT support, or R&D cost-sharing — the TNMM is the most commonly accepted method. This method benchmarks the net profit margin of the tested party against comparable independent entities. The Pre-IPO company must select the tested party as the entity with the least complex functions and the most reliable data. For a Hong Kong-listed Pre-IPO company with a PRC operating subsidiary, the tested party is typically the PRC entity. The 2023 IRD transfer pricing practice note (IRDPN 59) provides a safe harbour for routine services at a cost-plus margin of 5-10%, but the HKEX Listing Division has indicated that for RPTs material to the listing application, a margin above 15% requires a detailed functional analysis.

The Transactional Profit Split for Joint Development

Pre-IPO companies engaged in joint development of intellectual property with connected persons — common in biotech and AI — must use the Transactional Profit Split method. This requires allocating the combined profits from the IP based on each party’s relative contributions, measured by functions performed, assets used, and risks assumed. The 2024 listing of Company C, an AI chip developer, disclosed a profit split ratio of 70:30 for a jointly developed algorithm, based on a functional analysis that attributed 70% of the R&D risk to the listed entity. The sponsor engaged a Big Four transfer pricing firm to prepare the analysis, which ran to 180 pages in the prospectus.

Documentation and Disclosure Requirements

The HKEX’s Listing Rules require that the pricing policy for each RPT be documented in a written agreement, and that the agreement be disclosed in the prospectus. Rule 14A.52 requires that the agreement have a fixed term not exceeding three years, with a renewal mechanism subject to independent shareholder approval. For Pre-IPO companies, the Listing Division will request the following documents: the RPT agreement, the pricing memorandum, the comparability analysis, the functional analysis, and the independent valuation report (where applicable).

The Pricing Memorandum

The pricing memorandum must contain: a description of the transaction, the pricing methodology used, the selection of the tested party, the comparable data set, the adjustments made for differences, and the conclusion that the price is arm’s length. The 2024 SFC consultation paper on RPT pricing proposed that the pricing memorandum be signed off by the reporting accountant and the sponsor’s compliance officer. The final rules, effective 1 January 2025, require that the pricing memorandum be included in the sponsor’s due diligence file and made available to the Listing Division upon request.

Disclosure in the Prospectus

The prospectus must include a summary of the pricing policy for each material RPT, including the methodology, the key assumptions, and the range of acceptable prices. The 2024 listing of Company D, a biotech firm, disclosed in its prospectus that its R&D service fee to its founder’s Cayman vehicle was priced at cost plus 8%, based on the TNMM, with a benchmarked range of 5-12%. The prospectus also disclosed the identity of the comparable companies (five PRC CROs listed on the Shenzhen Stock Exchange) and the adjustments made for functional differences.

Common Pitfalls and Regulatory Scrutiny

The SFC’s enforcement record for 2024 and early 2025 reveals three recurring deficiencies in Pre-IPO RPT pricing policies. First, the use of “cost plus” without a documented cost base. In the 2024 enforcement against Sponsor E (SFC, 2024), the sponsor accepted a management-prepared cost allocation that included HKD 15 million in unsubstantiated overheads. The SFC fined the sponsor HKD 12 million and required a restatement of the prospectus. Second, the failure to benchmark against external data. The Listing Division will reject a pricing analysis that relies solely on internal management estimates without reference to independent market data. Third, the absence of a functional analysis for service agreements. The SFC’s 2023 guidelines explicitly state that a functional analysis is mandatory for any RPT exceeding HKD 50 million.

The 2025 Enforcement Trend

In Q1 2025, the SFC issued “show cause” letters to three Pre-IPO companies under Chapter 18C, each relating to RPT pricing. The common thread was the use of a flat 10% margin for all intra-group services, without differentiation by function or risk. The SFC’s position, as stated in its 2025 enforcement bulletin, is that a single margin for all services is prima facie evidence of non-arm’s length pricing. The companies were required to commission retrospective transfer pricing studies and to restate their financial statements for the three years preceding the listing application.

The Role of the Independent Non-Executive Director (INED)

Under Rule 14A.55, the INEDs must review the RPT pricing policy annually and confirm that it is fair and reasonable. For Pre-IPO companies, the Listing Division expects the INEDs to have been involved in the pricing process from the outset, not merely to sign off on a management-prepared document. The 2024 listing of Company F disclosed that its INEDs had attended three pricing committee meetings and had received independent legal advice on the arm’s length analysis.

Actionable Takeaways for Pre-IPO Companies

1. Commission a retrospective transfer pricing study for all RPTs entered into within the 24 months preceding the A1 filing, using one of the five OECD methods, and ensure the study is signed off by a qualified transfer pricing professional with Hong Kong experience.

2. Establish a written RPT pricing policy, approved by the board, that specifies the methodology for each category of transaction (tangible assets, services, IP, financial arrangements) and requires a functional analysis for any transaction exceeding HKD 50 million.

3. Engage the sponsor and reporting accountant in the pricing process at least 12 months before the intended listing date, and ensure that the pricing memorandum is included in the due diligence file as a separate, indexed document.

4. Ensure that all RPT agreements have a fixed term not exceeding three years, with a renewal mechanism that requires independent shareholder approval under Rule 14A.52, and that the agreements are disclosed in the prospectus with the pricing methodology and key assumptions.

5. For any RPT involving intellectual property, intangible assets, or services without a market price, obtain an independent valuation report from a recognised valuation firm, and ensure the report addresses both the pricing methodology and the arm’s length conclusion.
