Ab&B Bio-Tech (02627.HK) announced a trading suspension effective April 1, 2026, due to incomplete audit procedures regarding fund investments and consultancy payment verifications. Although the earnings preview estimated 2025 revenue at RMB 446–493 million (up ~72%-90% YoY) with narrowed losses, the share price plunged approximately 58.94% in the 14 trading days prior to suspension due to profit-taking following its inclusion in the Stock Connect. The company is heavily dependent on its core product, the quadrivalent influenza subunit vaccine "Huierkangxin®," which contributes approximately 99% of its total revenue, indicating an extremely concentrated income source.
CaoCao Inc. (02643.HK) recently released its 2025 annual report, showing total revenue of RMB 20.2 billion (+37.7%) and a narrowed net loss of RMB 614 million, with adjusted profit turning positive in the fourth quarter for the first time. However, these results failed to lift the stock in the secondary market; as of March 31, 2026, it closed at HK$25.60, down nearly 39% from its IPO price. Core operational and structural challenges remain: the company is highly dependent on aggregation platforms for over 85% of its orders, with RMB 8.40 of every RMB 100 in revenue flowing to external platforms, significantly eroding profit margins.
Distinct Healthcare (02677.HK) recently disclosed its 2025 financial results, with revenue reaching RMB 1.065 billion (+11.1% YoY) and net profit hitting RMB 135 million (+61.2% YoY). Despite reaching a profitability turning point, the stock has continued to slide. As of March 30, 2026, it closed at HK$38.26, a decline of approximately 36.13% from its offer price of HK$59.90. As China’s third-largest private mid-to-high-end integrated medical institution, its market share is only 2.0%. Physical medical services contribute over 92% of revenue, while revenue growth is slowing and remains highly dependent on the Tier-1 markets of Beijing, Shanghai, Guangzhou, and Shenzhen (accounting for >70%).
As the world’s first autonomous driving benchmark with a "US + HK" dual primary listing, Pony AI (02026.HK) closed at HK$74.6 on March 27, 2026, down over 46% from its offer price. Despite 2025 revenue hitting $90 million (+20% YoY) and a significantly narrowed GAAP net loss, the capital market remains cautious about its financial health. The company’s adjusted non-GAAP net loss expanded to $174 million in 2025, with a net operating cash outflow of $165 million, indicating it has yet to close the "self-sustaining" loop.
After its share price was "halved" shortly after listing, Hanx Biopharmaceuticals (03378.HK) saw a strong recovery in the first quarter of 2026. As of March 26, it closed at HK$27.64, with a cumulative 2026 gain of 72.97%. The rebound is primarily driven by the approval of HX111—a global First-in-Class OX40-targeted ADC—to enter clinical trials. While the R&D pipeline holds 10 candidate drugs and the core product HX009 (PD-1/SIRPαbispecific) has completed Phase I trials in multiple regions, Phase III studies have yet to begin, indicating a significant cycle remains before commercialization.

Following a massive surge of nearly 12 times in the previous period, 160 Health (02656.HK) suffered a heavy blow on March 18, 2026, closing at HK$103.40 with a single-day drop of 31.52%, wiping out over HK$16 billion in market value. The day before the crash, the company issued a positive profit alert for 2025, expecting an adjusted net profit of RMB 3 million to 5 million, its first annual profit since listing, mainly due to significantly reduced operating expenses through AI empowerment. While benefiting from the Stock Connect and AI agent concepts, the key to its valuation stability remains whether it can convert "registration platform" traffic into a solid AI competitive moat in a fragmented market surrounded by giants like JD Health and AliHealth.
