Fundamental analysis 300445.SZ (Beijing ConST Instruments Technology Inc.)

Updated on 10/14/2026

Method and analysis by Lubin Danilo, founder of Lubin Investment. Score computed automatically, with no human opinion.

We analyzed Beijing ConST Instruments Technology stock against the 10 quality criteria of Lubin Investment. The company gets a quality score of 8/10, meaning high quality, and a P/FCF valuation multiple of 22.0×.

Beijing ConST Instruments Technology is a quality company by our criteria, but the price does not follow: the free cash flow multiple stays high. A great company bought too expensively is still a poor investment, so this is typically one to watch while waiting for a better entry point.

Sector: Scientific & Technical Instruments. Listing: SZ. Current price: 17.60 CNY.

Lubin scoring methodology

Beijing ConST Instruments Technology Inc. (300445.SZ)'s score is calculated automatically from 10 objective financial criteria, with no human intervention or opinion. Each criterion is validated (YES / PARTIAL / NO) based on thresholds drawn from the financial literature (Warren Buffett, Michael Mauboussin, Aswath Damodaran). The final score is the sum of validations.

The thresholds come from the financial literature, not from our preferences: see the valuation work of Aswath Damodaran (NYU Stern) and the SEC investor education resources (investor.gov).

The 10 quantitative criteria analyzed

1. Profitable: net margin > 5%
2. Growing revenue: revenue growing > 10%/year over 5 years
3. Growing earnings per share: FCF per share adjusted for stock-based compensation, > 10%/year over 5 years
4. Share count under control: stable or declining (net buybacks = value creation for shareholders)
5. Growing revenue per employee: revenue and revenue per employee both grow ≥ 10%/year over 5 years; partial when only one growth driver reaches its tier (fallback: free cash flow margin > 10% when employee history is unavailable)
6. Expanding margins: operating margin widens over 5 years (operating leverage)
7. Return on invested capital: Cash ROCE > 15% per year
8. Debt under control: net debt repayable in less than 3 years of free cash flow
9. Earnings converted to cash: free cash flow exceeds accounting net income
10. Net collection period: short or negative cash conversion cycle

Its price against peers

Against the 5 other Scientific & Technical Instruments stocks we have scored, Beijing ConST Instruments Technology trades at 22.0× its free cash flow, versus a median of 21.8× for that basket. On price alone, Beijing ConST Instruments Technology is therefore more expensive than its peers. That says nothing about its quality: at Lubin Investment, quality and price are judged separately, and a low multiple is only a bargain if the quality holds up.
