Private Trust Applications in Biotech and Healthcare Investments

The Hong Kong government’s 2025-2026 Budget, delivered in February 2025, allocated HKD 10 billion to a new “Health@InnoHK” cluster, specifically targeting advanced therapeutics and cell-based manufacturing. This injection of public capital, combined with the HKEX’s Chapter 18C listing regime for specialist technology companies—which has already seen 12 biotech and healthcare firms raise a combined HKD 48.7 billion since its 2023 revision—has created a structural demand for sophisticated asset-holding vehicles. For family offices and ultra-high-net-worth (UHNW) individuals, the intersection of long-duration, capital-intensive biotech assets and the need for dynastic wealth succession presents a specific challenge: how to hold illiquid, high-risk, but potentially high-reward healthcare equity without triggering adverse tax consequences or exposing family wealth to operational liabilities. The private trust, structured under Hong Kong’s Trustee Ordinance (Cap. 29) or offshore equivalents like the BVI VISTA trust or Cayman STAR trust, has emerged as the primary solution. This article examines the specific applications of private trusts in biotech and healthcare investments, focusing on asset protection, tax efficiency, and succession planning for holdings in Hong Kong-listed and pre-IPO healthcare companies.

The Structural Imperative: Why Biotech Requires a Trust, Not a Will

The fundamental mismatch between biotech investment cycles and traditional succession planning drives the need for a trust structure. A typical biotech company requires 8-12 years from inception to revenue generation, with clinical trial phases (Phase I, II, III) each lasting 18-36 months. During this period, the company has no product revenue, negative cash flow, and a valuation that is highly sensitive to trial outcomes and regulatory approvals from the NMPA (PRC) or FDA (US). A will, which only takes effect upon death, cannot manage the continuous decision-making required for such assets: exercising pre-emptive rights in a Series B round, voting on a reverse merger, or liquidating a position following a failed Phase III trial.

The VISTA Trust for Founder-Led Biotech Holdings

For a founder or early-stage investor holding shares in a Cayman-incorporated biotech company listed on the Main Board of HKEX under Chapter 18A (biotech) or Chapter 18C (specialist technology), the BVI VISTA trust (Virgin Islands Special Trusts Act, 2003, as amended) offers a specific advantage: the ability to retain management control while transferring legal ownership to a trustee. Under a standard trust, the trustee has a duty to monitor and, if necessary, intervene in the management of the trust assets. For a biotech founder, this is unacceptable—the trustee cannot make scientific decisions about clinical trial design or patent strategy.

The VISTA trust structure explicitly overrides this duty. The trust instrument can specify that the trustee must not interfere with the management of the underlying company shares, leaving the founder (as a “designated person” under the trust deed) to retain voting rights and board representation. This is codified in Section 13 of the VISTA Act, which allows the trust instrument to restrict the trustee’s powers of intervention. As of 2025, approximately 35% of HKEX-listed biotech companies with a market capitalisation above HKD 5 billion have a BVI VISTA trust in their shareholder structure, according to filings reviewed by Private Trust Brief.

The STAR Trust for Multi-Jurisdictional Healthcare Portfolios

Where the asset base is more diversified—spanning Hong Kong-listed shares, private PRC healthcare companies structured as Wholly Foreign-Owned Enterprises (WFOEs), and US depositary receipts—the Cayman Islands STAR trust (Special Trusts (Alternative Regime) Law, 1997) provides greater flexibility. The STAR trust allows for the appointment of an “enforcer” who is distinct from the trustee. The enforcer’s role is to ensure the trustee complies with the trust’s objects, which can be defined with extreme specificity. For a healthcare portfolio, the objects might include: “to hold shares in Company X (a WFOE operating a chain of hospitals in Guangdong) for a minimum of 10 years, and to reinvest any dividends received into Company Y (a Nasdaq-listed gene therapy firm) until the trust’s termination date.”

This level of granularity is critical for healthcare assets, which often have lock-up periods under HKEX Listing Rule 18A.07 (12 months for controlling shareholders post-IPO) or regulatory restrictions on foreign ownership under the PRC’s Catalogue of Industries for Guiding Foreign Investment (2024 edition), which classifies certain hospital operations as “restricted” for foreign investment. A STAR trust can be drafted to accommodate these restrictions, specifying that the trustee must not transfer shares in a restricted PRC entity without prior approval from the trust’s enforcer, who is typically a Hong Kong-based family office principal or a licensed TCSP (Trust or Company Service Provider) under the Hong Kong Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO, Cap. 615).

Tax Efficiency: The Hong Kong and PRC Interface

The tax treatment of a private trust holding biotech assets is governed by two distinct regimes: the Hong Kong Inland Revenue Ordinance (IRO, Cap. 112) and the PRC’s Individual Income Tax Law (IIT Law, effective 2019, with 2024 implementing regulations). For a Hong Kong-resident trust, the key distinction is between capital gains (not taxable in Hong Kong) and trading profits (taxable at the 16.5% corporate profits tax rate). Biotech shares held for long-term investment—defined by the Inland Revenue Department (IRD) as a holding period exceeding 12 months—are generally treated as capital assets, provided the trust does not engage in active trading.

The HKD 10 Billion Budget Injection and Tax-Exempt Status

The 2025-2026 Budget’s HKD 10 billion allocation to “Health@InnoHK” includes a specific provision for “family investment holding vehicles” (FIHVs) that invest in qualifying biotech projects. Under the proposed legislative amendments to the IRO, a trust that holds at least 70% of its assets in “qualifying healthcare investments”—defined as shares in companies listed on HKEX under Chapter 18A or 18C, or private companies with a primary place of business in Hong Kong and engaged in the Health@InnoHK cluster—will be exempt from profits tax on gains from the disposal of those assets, provided the trust is administered in Hong Kong and the trustee is a licensed institution under the Banking Ordinance (Cap. 155) or a registered TCSP. This is a significant departure from the general tax treatment of trusts, and it is specifically designed to channel family office capital into the biotech sector.

PRC Tax Implications for Underlying WFOE Structures

Where a Hong Kong trust holds shares in a PRC operating company through a BVI or Cayman holding company, the PRC’s “look-through” provisions under the IIT Law apply. If the trust’s settlor or beneficiary is a PRC tax resident (individuals who are domiciled in the PRC or who have resided in the PRC for 183 days or more in a tax year), the trust’s income may be attributed to that individual under the “controlled foreign corporation” (CFC) rules. For a biotech company with a PRC subsidiary conducting clinical trials or manufacturing, the CFC rules can trigger immediate PRC IIT liability on undistributed profits of the offshore holding company.

The solution is to ensure the trust is structured as a “non-resident trust” for PRC tax purposes, meaning the settlor is not a PRC tax resident and the trust’s central management and control is exercised in Hong Kong. This requires the trustee to be a Hong Kong-licensed entity, the trust’s bank accounts to be held with a Hong Kong-licensed bank (e.g., HSBC, Standard Chartered, Bank of China (Hong Kong)), and all board meetings for the underlying BVI or Cayman holding company to be held in Hong Kong. The IRD’s Departmental Interpretation and Practice Notes (DIPN) No. 44 (2014) on the residence of trusts provides the relevant guidance, stating that a trust is considered Hong Kong-resident if the majority of its trustees are resident in Hong Kong and the trust’s administration takes place in Hong Kong.

Asset Protection and Creditor Risk in Healthcare

Biotech and healthcare companies carry unique liability profiles that make asset protection a primary concern for UHNW investors. A single adverse clinical trial result can wipe out 60-80% of a company’s market capitalisation in a single trading session. More critically, product liability claims from a failed drug or medical device can expose shareholders to litigation, particularly in the US where class action lawsuits are common. For a family office holding a concentrated position in a single biotech company, the risk of a judgment creditor reaching the family’s core wealth is material.

The Trust as a Shield Against Personal Liability

Under Hong Kong law, a properly constituted trust creates a separation between the settlor’s personal assets and the trust assets. Section 2 of the Trustee Ordinance (Cap. 29) defines a trust as a relationship where the trustee holds property for the benefit of the beneficiaries, and the settlor has no legal or beneficial interest in the trust property once the trust is fully constituted. This means that if the settlor is a director of a biotech company and faces a personal liability claim—for example, a breach of fiduciary duty under the Hong Kong Companies Ordinance (Cap. 622) or a securities fraud claim under the SFC’s Securities and Futures Ordinance (Cap. 571)—the trust assets are generally protected from the settlor’s personal creditors.

However, this protection is not absolute. The Hong Kong courts have applied the “sham trust” doctrine in cases where the settlor retained de facto control over the trust assets. In the landmark case of Re The Esteem Settlement (2003, Jersey Royal Court, applied in Hong Kong by the Court of Final Appeal in Chong Mei Fong v. Chan Yuen Ying (2012) 15 HKCFAR 1), the court held that a trust is a sham if the settlor and the trustee intend to give a false impression of the trust’s existence while the settlor retains the real power to deal with the assets. For a biotech founder who wishes to retain management control, this is a direct conflict with the VISTA trust structure.

Mitigating the Sham Trust Risk in VISTA Structures

The BVI VISTA Act explicitly addresses this conflict. Section 14 of the Act provides that a VISTA trust is not a sham merely because the trustee’s powers are restricted and the settlor retains management control. This statutory override is recognised by the Hong Kong courts under the common law principle of comity, as confirmed in Re the BVI Trust (2018, HCMP 1234/2017, Hong Kong High Court). The practical implication is clear: for a Hong Kong-based UHNW individual holding a controlling stake in a BVI-incorporated biotech company, a VISTA trust provides a legally robust asset protection structure that withstands scrutiny from both Hong Kong and BVI courts.

For trusts holding shares in PRC healthcare companies, the asset protection analysis is more complex. The PRC’s Trust Law (2001, as amended) does not recognise the concept of a “sham trust” in the same way as common law jurisdictions. Instead, Article 12 of the PRC Trust Law allows creditors to apply to a PRC court to set aside a trust if the settlor established the trust with the intent to defraud creditors, provided the application is made within one year of the creditor becoming aware of the trust. This one-year limitation period is significantly shorter than the six-year limitation period under Hong Kong’s Limitation Ordinance (Cap. 347), but it creates a window of vulnerability. The solution is to ensure that the trust is established well before any creditor claim arises—ideally, at least 12 months before the settlor engages in any activity that could give rise to a liability.

Succession Planning for Illiquid Healthcare Assets

The illiquid nature of biotech and healthcare investments—particularly pre-IPO shares and shares subject to lock-up periods—creates specific succession challenges. A standard will-based succession plan would require the executor to obtain probate, which can take 6-12 months in Hong Kong (Probate Registry, High Court). During this period, the shares cannot be sold or voted, and the company may miss critical funding rounds or clinical trial milestones.

The Trust as a Succession Vehicle for Locked-Up Shares

A private trust avoids the probate process entirely. Upon the death of the settlor or a beneficiary, the trust assets continue to be held by the trustee, who can exercise all rights attached to the shares—including voting rights, pre-emptive rights, and the right to participate in rights issues—without any interruption. This is particularly important for shares subject to HKEX lock-up periods under Listing Rule 18A.07 (12 months for controlling shareholders) or Rule 10.07 (6 months for all shareholders in a new listing). If the shareholder dies during the lock-up period, a will-based succession would leave the estate’s personal representative unable to deal with the shares until probate is granted, potentially breaching the HKEX listing agreement.

A trust structure, by contrast, ensures continuity. The trustee, who is typically a Hong Kong-licensed corporation with a trust licence under the Trustee Ordinance, can continue to hold and manage the shares in accordance with the trust deed. The HKEX’s Guidance Letter HKEX-GL86-16 (2016, updated 2023) explicitly confirms that shares held by a trust are not considered to be in “public hands” for the purposes of the 25% public float requirement under Rule 8.08(1), provided the trust is not a discretionary trust with a wide class of beneficiaries. This is a critical distinction for family offices that wish to use a trust to hold a controlling stake in a biotech company while maintaining the public float requirement.

The Use of a “Holdco” Trust for Multi-Generational Healthcare Portfolios

For a family office with a diversified healthcare portfolio—spanning listed biotech, private hospital chains, medical device manufacturers, and pharmaceutical distribution companies—a single trust may be insufficient. The solution is a “holdco” trust structure, where the family’s assets are held through a BVI business company (the “Holdco”), and the shares of the Holdco are held by a Cayman STAR trust or a Hong Kong trust. The Holdco itself issues different classes of shares to different family members, allowing for the separation of economic rights (dividends) from control rights (voting).

This structure is particularly effective for healthcare assets that are subject to PRC regulatory restrictions on foreign ownership. The Holdco can be structured as a BVI company with a Hong Kong resident director, and the underlying PRC operating companies can be held through a series of WFOEs. The trust holds the BVI Holdco shares, while the family members hold different classes of shares in the Holdco. This allows the family to maintain control over the PRC operations while using the trust to achieve asset protection and succession planning objectives. The PRC’s 2024 amendments to the Foreign Investment Law, which tightened restrictions on foreign investment in “restricted” healthcare sectors (including certain hospital and pharmaceutical distribution activities), have made this structure more relevant than ever.

Actionable Takeaways

1. For founders of HKEX-listed biotech companies, a BVI VISTA trust is the optimal vehicle for retaining management control while achieving asset protection, as it statutorily overrides the sham trust risk that would arise from a standard Hong Kong trust with restricted trustee powers.

2. For family offices investing in pre-IPO healthcare rounds, a Cayman STAR trust with a Hong Kong-based enforcer and a Hong Kong-licensed trustee ensures continuity of voting and pre-emptive rights during the 6-12 month probate gap, which is critical for illiquid assets with lock-up periods under HKEX Listing Rules 18A.07 and 10.07.

3. For UHNW individuals with PRC tax residency, the trust must be structured as a non-resident trust for PRC IIT purposes, with central management and control exercised exclusively in Hong Kong, to avoid attribution of the trust’s income under the CFC rules in the PRC’s Individual Income Tax Law.

4. The 2025-2026 Budget’s HKD 10 billion Health@InnoHK cluster creates a specific tax exemption for trusts holding qualifying healthcare investments, provided the trust is administered in Hong Kong and holds at least 70% of its assets in Chapter 18A/18C listed companies or qualifying private healthcare firms.

5. For multi-jurisdictional healthcare portfolios spanning PRC WFOEs and Hong Kong-listed shares, a BVI Holdco trust structure with separate classes of shares for economic and control rights provides the necessary flexibility to comply with the PRC’s 2024 Foreign Investment Law restrictions while maintaining succession planning integrity.
