• In SHEIN Global IPO: The Bull Case, we highlighted the key elements of the bull case. In this note, we outline the bear case.

• H1FY26 Balance Sheet Expansion is Strategic, Not Structural Decay: The sharp increase in Plover Bay’s inventory and receivables in H1FY26 is driven by proactive component stockpiling (specifically 5G cellular modules and chipsets) to facilitate the upcoming US manufacturing transition, alongside selectively extended Net 60/90 payment terms to major North American Managed Service Providers (MSPs) to secure multi-year government and transit contracts.
• Starlink is a Complementary Catalyst, Not a Disintermediator: Despite market concerns regarding Starlink’s entry into enterprise routers, the operational reality is that Starlink acts as a major demand driver for Peplink’s high-margin multi-WAN bonding hardware. Enterprise, maritime, and blue-light customers require the redundancy of Peplink’s SpeedFusion protocol to bond Starlink with terrestrial LTE/5G networks, preserving Plover Bay’s channel relationships.
• The US Spin-off Faces Severe Cross-Border Tax Friction: While a US listing would unlock a higher valuation multiple, the lack of a comprehensive double taxation treaty between the US and Hong Kong subjects all repatriated dividends from the US entity to the HK parent to a 30% withholding tax. Mitigation strategies like intercompany IP licensing will face intense IRS transfer pricing scrutiny under Section 482 rules, creating a significant drag on net shareholder payouts.

• We screen the Hong Kong-listed mainland stocks ahead of the HSCEI August 2026 review.
• The screen produces one ADD and one DELETE, and the DELETE fires only if the ADD lands.
• We note that the committee skipped the same ADD candidate last review but re-iterate our call.

• Zhongji InnoLight (3308 HK) IPO could not happen on a worse day, right after a US sell-off, but both the HK and the China mainland stock (300308 CH) will recover.
• H-Share float expansion, IPO arbitrage, and sector profit-taking created a tactical dislocation against intact fundamental bull cases. 
• Consensus Rating is overwhelmingly bullish. Analyst coverage shows ~87.5% “Strong Buy” and ~12.5% “Buy” with zero “Hold” or “Sell” ratings. Our model indicates the stock is short-term oversold.

• Montage Technology is a dominant player in the memory interface chip market, poised to capitalize on the secular growth trends of AI and cloud computing, driven by the industry’s transition to DDR5 memory.
• The company exhibits a robust financial profile, characterized by accelerating revenue growth, significant margin expansion, and strong operating cash flow generation.
• Despite strong fundamentals and a positive outlook, the company’s stock trades at a premium valuation, which presents a key risk for investors and makes it susceptible to shifts in market sentiment.

• Dominant Market Leader in a High-Growth Sector: Zhongji InnoLight is the world’s largest provider of optical interconnect solutions, a market experiencing explosive growth driven by the proliferation of AI, cloud computing, and data center expansion. The company holds a significant global market share, estimated at 21.2% in 2025, and is a key supplier to major hyperscalers like Nvidia, Google, Amazon, and Meta.
• Exceptional Financial Performance: The company is demonstrating remarkable financial results, with triple-digit percentage growth in revenue and net profit. In the first quarter of 2026, revenue surged 192% year-over-year to RMB 19.5 billion, while net profit grew 262% to RMB 5.73 billion, driven by strong demand for its high-speed optical modules (800G and 1.6T) which command higher profit margins.
• Geopolitical Risks and High Valuation Present Headwinds: Despite its strong market position and financial performance, the company faces significant risks related to US-China geopolitical tensions and a high valuation. A large portion of its revenue is derived from the US, making it vulnerable to trade restrictions and tariffs. Additionally, its valuation multiples are elevated, which could lead to volatility, as seen in the recent stock price correction and the initial dip in its Hong Kong IPO.
