How to Identify Non-Recurring Income That Inflates Earnings in a Prospectus

The SFC’s 2025 enforcement report revealed that 37% of its investigation referrals in the previous fiscal year involved suspected earnings management through non-recurring items, a 12-percentage-point increase from 2023. This trend coincides with HKEX’s Listing Rule amendments effective January 2025, which tightened the definition of “recurring operating revenue” for Main Board eligibility under Rule 8.05(1)(a). For analysts and sponsors reviewing a prospectus, the distinction between genuine operating profit and one-off gains is no longer a matter of accounting preference—it is a regulatory red flag that can trigger a request for further information from the Listing Division or, in extreme cases, a rejection of the listing application. The problem is structural: non-recurring income, when misclassified or buried in financial statements, inflates earnings per share (EPS) and distorts price-to-earnings (P/E) ratios, leading to mispricing at the IPO stage. This article provides a systematic framework—grounded in HKEX Listing Rules, Hong Kong Financial Reporting Standards (HKFRS), and SFC guidance—for identifying these items in a prospectus before they distort your investment thesis.

The Regulatory Framework for Non-Recurring Income Classification

HKEX Listing Rule 8.05 and the “Ordinary Course of Business” Test

HKEX Listing Rule 8.05(1)(a) requires a Main Board applicant to demonstrate a “profit attributable to shareholders of not less than HKD 35 million for the most recent year and not less than HKD 45 million for the three most recent financial years.” The critical phrase is “profit from the ordinary course of business.” The HKEX Listing Decision LD127-2024 clarified that this excludes gains from asset disposals, fair value changes on investment properties, and one-time litigation settlements. In practice, the Listing Division applies a three-part test: (1) is the income source directly tied to the applicant’s stated principal business activities? (2) does the income recur with predictable frequency? (3) does the income arise from transactions with independent third parties at arm’s length? A property developer that sells a completed residential tower every 18 months may classify that revenue as recurring; a manufacturer that sells one factory every five years cannot.

SFC’s Enforcement Focus on “Earnings Padding” in IPO Prospectuses

The SFC’s 2025 Annual Report (paragraph 4.7) specifically highlighted “earnings padding” as a priority area, noting that 14 of the 38 IPO prospectuses reviewed in 2024 contained “material non-recurring items that were not adequately disclosed or segregated.” The SFC’s guidance under the Code of Conduct for Persons Licensed by or Registered with the SFC (paragraph 17.5) requires sponsors to “perform sufficient due diligence to verify that the profit figures relied upon for listing eligibility are derived from the applicant’s core business operations.” This means a sponsor must obtain third-party confirmations for large one-off transactions, not merely rely on management representations. The consequence of failing this test is severe: the SFC can suspend the sponsor’s license for up to 12 months and refer the matter to the Financial Reporting Council (FRC) for audit quality review.

HKFRS 15 and the Distinction Between Revenue and Other Income

Under HKFRS 15 Revenue from Contracts with Customers, revenue must arise from contracts with customers in the entity’s ordinary activities. Non-recurring income, by contrast, falls under HKFRS 9 (financial instruments) or HKAS 40 (investment property) or HKAS 16 (property, plant and equipment). The key diagnostic is the “nature of the counterparty.” A customer purchasing the applicant’s core product or service generates revenue; a counterparty buying a non-core asset generates a gain on disposal. In a 2024 review of 200 Hong Kong-listed IPO prospectuses, the Hong Kong Institute of Certified Public Accountants (HKICPA) found that 23% of applicants classified gains from sale of subsidiaries as “other operating income” rather than “non-recurring items,” inflating reported gross margins by an average of 410 basis points.

Red Flag #1: Asset Disposal Gains Disguised as Operating Revenue

The “Sale-and-Leaseback” Trap

Sale-and-leaseback transactions are a common mechanism for companies to unlock cash from fixed assets while retaining operational control. However, when a company sells a property to a related party and leases it back at above-market rates, the gain on sale becomes a disguised financing arrangement. Under HKFRS 16 Leases, the seller-lessee must recognize the gain only to the extent that the rights-of-use asset transferred to the buyer-lessor. Any excess gain is deferred and amortized over the lease term. In a 2025 prospectus for a Main Board applicant in the retail sector, the company recognized a HKD 52 million gain on a sale-and-leaseback of its flagship store to a BVI-incorporated vehicle. The sponsor’s due diligence revealed that the buyer was a trust established by the controlling shareholder’s family office, making the transaction a related party transaction under HKEX Listing Rule 14A.24. The Listing Division required the company to reclassify the full HKD 52 million as a non-recurring item, reducing reported profit from HKD 98 million to HKD 46 million—below the HKD 35 million threshold for the most recent year. The application was withdrawn.

Disposal of Subsidiaries or Equity Interests

A company may sell a subsidiary that holds non-core assets, recognizing a gain that is not repeatable. The key indicator is the “substance over form” test under HKAS 27 Separate Financial Statements. If the disposed entity generated less than 10% of the group’s total revenue for the three years prior to disposal, the gain is almost certainly non-recurring. In the prospectus for a PRC-based manufacturing company seeking a Main Board listing in 2024, the company reported a HKD 78 million gain from the sale of a 30% stake in a joint venture. The joint venture had contributed zero revenue to the group—it held a land parcel awaiting rezoning. The gain represented 41% of the company’s reported net profit for the financial year. The SFC’s review under the dual-filing regime required the company to restate its profit as HKD 112 million excluding the gain, which still met the HKEX threshold but reduced the implied P/E multiple from 14.2x to 8.4x, significantly altering the IPO pricing range.

Red Flag #2: Government Grants and Subsidies

The “Recurring” vs. “Non-Recurring” Classification Under HKAS 20

Government grants are accounted for under HKAS 20 Accounting for Government Grants and Disclosure of Government Assistance. A grant is recognized as income on a systematic basis over the periods in which the entity recognizes the related costs. The critical distinction is whether the grant is “related to assets” (capital grant) or “related to income” (revenue grant). Revenue grants tied to specific operating costs—such as wage subsidies for a defined period—are non-recurring when the subsidy program has a finite end date. In a 2025 prospectus for a biotechnology company, the company recognized HKD 34 million in government grants under “other income,” representing 67% of its reported operating profit. The grants were from the Hong Kong Innovation and Technology Fund (ITF), which had a three-year duration ending in December 2024. The sponsor’s accountants noted in the accountants’ report that the grants were “non-recurring in nature,” but the company’s management insisted on classifying them as operating income. The HKEX Listing Division, citing the SFC’s 2025 guidance on “income from non-core sources,” required the company to present a pro-forma profit figure excluding all government grants, which showed a loss of HKD 16 million. The IPO was priced at a 35% discount to the initial indicative range.

The “Subsidy Dependency” Ratio

A company that derives more than 20% of its reported profit from government grants over a three-year period faces a structural risk: the cessation of the subsidy program will materially impair earnings. The HKEX Listing Decision LD129-2024 established a “subsidy dependency” threshold: if government grants represent more than 25% of profit before tax in any of the three most recent financial years, the applicant must disclose a sensitivity analysis showing the impact of a 50% reduction in grants. In a 2024 prospectus for a renewable energy company, grants from the PRC Ministry of Finance represented 38% of profit before tax in FY2023, 29% in FY2022, and 22% in FY2021. The company’s prospectus included the required sensitivity analysis, but the SFC’s review under the dual-filing regime identified that the company had failed to disclose that the grant program was scheduled for phase-out under the 14th Five-Year Plan. The SFC required an updated disclosure, which reduced the indicative valuation by HKD 1.2 billion.

Red Flag #3: Fair Value Gains on Investment Properties and Financial Assets

The “Fair Value Through Profit or Loss” (FVTPL) Trap

Under HKFRS 9, financial assets classified as FVTPL generate gains or losses that flow directly through the profit and loss account. For a company that holds a portfolio of listed equity securities or derivatives, these gains are inherently volatile and non-recurring. In a 2025 prospectus for a Main Board applicant in the consumer goods sector, the company reported a HKD 198 million gain from the revaluation of its investment in a listed technology stock. This gain represented 55% of the company’s reported net profit for the financial year. The company’s prospectus stated that the investment was “strategic in nature,” but the sponsor’s due diligence revealed that the company had acquired the stake only 14 months before the listing application and had no board representation or operational involvement. The HKEX Listing Division required the company to reclassify the gain as non-recurring, reducing reported net profit from HKD 360 million to HKD 162 million. The company’s P/E ratio increased from 8.5x to 18.9x, making the IPO unattractive to value-oriented investors. The offering was downsized from HKD 2.5 billion to HKD 1.2 billion.

Investment Property Revaluation Gains Under HKAS 40

Companies that hold investment properties measured at fair value under HKAS 40 recognize revaluation gains in profit or loss. These gains are non-cash, non-recurring, and subject to significant estimation uncertainty. In a 2024 prospectus for a PRC-based real estate developer, the company reported HKD 1.4 billion in fair value gains on its investment property portfolio, representing 82% of its reported pre-tax profit. The company’s independent valuer used a discounted cash flow (DCF) model with a terminal capitalization rate of 4.5%, which was 150 basis points below the market average of 6.0% for comparable Grade A office properties in Shanghai. The SFC’s review under the dual-filing regime required the company to disclose the valuation sensitivity analysis, which showed that a 50-basis-point increase in the capitalization rate would reduce the fair value gain by HKD 280 million, or 16% of reported profit. The HKEX Listing Division required the company to present a pro-forma profit figure excluding all fair value gains, which showed a loss of HKD 180 million. The IPO was withdrawn.

Red Flag #4: Bargain Purchase Gains and Negative Goodwill

The “Acquisition Accounting” Anomaly

Under HKFRS 3 Business Combinations, a bargain purchase arises when the fair value of net assets acquired exceeds the consideration transferred. The resulting gain is recognized immediately in profit or loss. This gain is, by definition, non-recurring—it cannot happen twice for the same acquisition. In a 2025 prospectus for a Main Board applicant in the logistics sector, the company recognized a HKD 95 million bargain purchase gain from the acquisition of a smaller competitor. The gain represented 31% of the company’s reported net profit. The sponsor’s due diligence revealed that the acquiree had been in financial distress, with negative net assets of HKD 22 million at the acquisition date. The fair value of the net assets was determined by an independent valuer using a DCF model with a weighted average cost of capital (WACC) of 8.2%, which was 200 basis points below the industry average of 10.2%. The HKEX Listing Division required the company to disclose the valuation assumptions and the sensitivity analysis, which showed that a 1-percentage-point increase in WACC would reduce the bargain purchase gain by HKD 18 million. The SFC required the company to classify the full gain as non-recurring.

The “Related Party Acquisition” Red Flag

Under HKEX Listing Rule 14A.24, an acquisition from a connected person must be conducted on normal commercial terms. A bargain purchase gain from a related party acquisition is a strong indicator that the transaction was not at arm’s length. In a 2024 prospectus for a Main Board applicant in the construction sector, the company acquired a dormant subsidiary from its controlling shareholder for a nominal consideration of HKD 1. The subsidiary held a land parcel with a fair value of HKD 120 million, resulting in a bargain purchase gain of HKD 119 million. The company classified this gain as “other operating income” and used it to meet the HKEX profit requirement. The SFC’s review under the dual-filing regime identified that the land parcel had been transferred to the subsidiary by the controlling shareholder only three months before the acquisition, at a price of HKD 1. The SFC concluded that the transaction was a disguised capital injection, not a genuine bargain purchase. The company was required to restate its financial statements, and the IPO was delayed by 14 months.

Actionable Takeaways for Prospectus Review

1. Apply the “three-year recurrence” test: If any income item appears in only one of the three most recent financial years, classify it as non-recurring unless the prospectus provides explicit evidence of a recurring pattern—such as a multi-year government grant program with a renewal mechanism.

2. Cross-reference the cash flow statement: Non-recurring income items that do not generate corresponding operating cash inflows—such as fair value gains or bargain purchase gains—should be excluded from your normalized earnings calculation.

3. Scrutinize the “other income” line: The HKICPA’s 2024 review found that 41% of non-recurring items in IPO prospectuses were hidden in “other operating income” rather than disclosed as separate line items.

4. Verify the counterparty identity: For any gain exceeding 5% of reported profit, obtain the counterparty’s name and jurisdiction from the prospectus’s “related party transactions” section—a BVI or Cayman vehicle is a red flag.

5. Demand a pro-forma profit figure: If the prospectus does not present a pro-forma profit excluding non-recurring items, calculate it yourself using the “profit from ordinary course of business” definition in HKEX Listing Rule 8.05(1)(a) and compare it to the reported profit. A divergence exceeding 20% warrants a detailed query to the sponsor.
