Fair value per share

Under review: every model's value for Martin Midstream Partners L.p. is far from the share price, which usually points to a data problem (a merger, a share-count change, a one-off) rather than a bargain or a bubble.

Price vs value

Under review: our cash-flow value ($15.03) was left out of our combined valuation (it is 7.59x the share price, outside the 0.2-5x range we accept), so it can't be the basis of a rating. We'll show the comparison once resolved.

Valuation

Martin Midstream Partners L.p. valuation models and calculator

Fundamentalytics rating

model v1.6 · 2026-11-03

Not rated: held for review: our cash-flow value ($15.03) was left out of our combined valuation (it is 7.59x the share price, outside the 0.2-5x range we accept), so it can't be the basis of a rating.

Our value per share comes from a discounted-cash-flow model of Martin Midstream Partners L.p.'s free cash flow after stock-based pay ( $51.7M, FY2026 Q3 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.

Valuation models

We value Martin Midstream Partners L.p. as an operating company, with every model that fits that kind of business. Cost of equity 7.5%: the 10-year Treasury yield (4.9%) plus a beta of 0.58 times a 4.5% equity risk premium.

Moat

64 /100

    Cash operating profit has been a median 50.9% of total assets over 9 years.

  • Pricing power 11 / 20

    Gross margin has been a median 46.1%, moving by 7.3 percentage points (standard deviation) across 9 years.

  • Durability 11 / 20

  • Cash conversion 10 / 20
