How we got here: a discounted-cash-flow model of Compx International Inc's free cash flow after stock-based pay with after-tax interest added back ($20.8M, FY2026 Q2 TTM), growing 3.1% a year for five years and fading to 2.5%, discounted at 8.5%. Lower and higher growth cases span ~$27–~$44 ; that spread sets a 25% margin before we rate Buy or Sell.

Produced by Fundamentalytics' automated valuation model on November 3, 2026, using delayed market prices. Rating meanings, methodology and conflicts: recommendations disclosure and research disclaimer. General research, not personal advice — it does not consider your circumstances. Prices can fall as well as rise.

Our value per share comes from a discounted-cash-flow model of Compx International Inc's free cash flow after stock-based pay ( $20.8M, FY2026 Q2 TTM, with after-tax interest added back): growth for five years as below (the first two years from forecasts, guidance and the company's record), fading to 2.5%, discounted at 8.5%, then cash added and debt and other claims subtracted. These are model values under stated assumptions, not price targets or recommendations.

Valuation models

We value Compx International Inc as an operating company, with every model that fits that kind of business. Cost of equity 8.5%: the 10-year Treasury yield (4.9%) plus a beta of 0.78 times a 4.5% equity risk premium.

Moat

58 /100

Moderate moat

How hard Compx International's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.

  • Returns on capital 10 / 20

    Cash operating profit has been a median 8.6% of total assets over 10 years.

  • Pricing power 11 / 20

    Gross margin has been a median 30.7%, moving by 1.4 percentage points (standard deviation) across 10 years.

  • Durability 14 / 20

    Operating margin has been a median 14.3%; its worst year was 12.2%.

  • Cash conversion 16 / 20

    Free cash flow was positive in 10 of 10 years, at a median 11.3% of revenue.

  • Discipline 12 / 20

    The diluted share count fell 1.0% over five years.

AI disruption exposure: Medium. In this industry, AI could change how the product is made or sold, without replacing the core asset. The score above includes a 5-point deduction for that exposure (63 before it).
