model v1.6 · 2026-11-03

Not rated: share count (2m) is 0.25x the cover-page count (10m): held for review.

Our value per share comes from a discounted-cash-flow model of Castor Maritime Inc.'s free cash flow after stock-based pay ( $6.2M, FY2025 Q4 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.

The inputs used by the models below have passed source checks. Individual model values are available below and in the interactive valuator. Their differences are shown explicitly; the platform combined value and recommendation remain withheld.
