Select Model
Rating:45Neutral
Price Target:HKD 0.98â–¼(-2.50% Downside)
Action:reiterated
Date:08/19/26

The overall score is low because the company’s financial profile is very weak, with revenue dropping to zero, persistent large losses and continued cash burn despite a recently strengthened balance sheet. This is only partially offset by a mildly improving technical setup and a valuation profile that remains speculative due to negative earnings and no dividend support.

Positive Factors
Narrower LossesThe reduction in net loss provides a modest improvement in the company’s financial trajectory and may indicate tighter cost control or progress in development efficiency. However, the business remains far from breakeven, so this is an incremental positive rather than evidence of established profitability.
Negative Factors
Revenue CollapseRevenue of zero in the latest reported year demonstrates that the company has not yet established a dependable commercial base. Continued minimal or absent revenue limits internal funding capacity, leaves results highly volatile, and makes future progress heavily dependent on pipeline advancement or external transactions.
