MoatlyAI Insights

The moat score of 67 and management score of 74 point to a business with durable competitive position and capital discipline, though the underlying numbers are modest rather than exceptional: return on invested capital sits at 4.1%, gross margin at 23.6%, and debt to equity is low at 0.2x. Free cash flow yield is 2.3%, which is a thin cushion relative to the size of the balance sheet these scores are meant to reward.

The valuation rests entirely on earnings, since both the 10-cap and payback time methods return $0.00. Using an 8.6% growth rate, deliberately held below the 9.0% actually measured, and a 16.2x exit multiple, the model produces a consensus buy price of $81,985.39 against a market price of $516.38, giving a margin of safety score of 100.

That gap is the tension here. Quality scores in the high 60s and 70s sit alongside low current returns on capital, while the price itself looks inexpensive against a conservative growth assumption. The scores describe durability and discipline; the price test describes room, but both draw on a modest set of returns metrics rather than any faster path forward.
