Ok Biotech Co., Ltd.

(TWSE:4155)

Select Model
Rating:63Neutral
Price Target:TWD 19.00â–²(13.77% Upside)
Action:initiatedcoverage
Date:11/10/26

The overall score of 63 reflects a company with a stable balance sheet and strong bullish technical momentum, offset by significant fundamental risks. The most impactful factor is the persistent negative free cash flow, which raises concerns about the sustainability of its capital-intensive operations. Positively, the stock shows robust price momentum above all key moving averages and a reasonable valuation with a low P/E ratio. The company's financial health hinges on its ability to convert investments into profitable growth that generates positive cash flow.

Positive Factors
Improved Profitability and Gross MarginNet income moved from near breakeven in 2023 to solid profitability in 2024–2025, while gross margin recovered to about 27.6% in 2025. This indicates improved operating economics and gives the company a stronger base to fund product development and commercial execution over coming quarters.
Negative Factors
Persistent Negative Free Cash FlowFree cash flow was negative in every year from 2021 through 2025, including a large deficit in 2024 and another shortfall in 2025. Persistent inability to convert operations into surplus cash reduces funding flexibility and may require continued investment financing if conditions tighten.
