MSB

Mesabi Trust is not an operating company — it is a pass-through royalty trust with no directors, officers or employees, whose entire income depends on iron-ore pellet shipments from a single lessee, Northshore Mining (Cliffs). That structure is the whole investment case and the whole risk. FY2025 was a banner year: revenue of $98.6M (+331%) and net income of $93.3M (+391%) at a 94.6% net margin, translating to roughly $7.12 of earnings per unit against a $25.66 price — a trailing P/E near 3.6 and a P/S of 3.4. The balance sheet is pristine in the ways that matter for a trust: $100M of cash (nearly 30% of the $337M market cap) and $23.3M of equity, with the $78.4M liability jump most consistent with distributions payable rather than borrowings.

The problem is durability. The five-year history is violently cyclical — revenue swung from $26.0M (FY2021) to $71.5M (FY2022) to just $7.74M (FY2023) to $22.9M (FY2024) before this year's $98.6M spike. That FY2023 collapse maps directly to the operator's decision to idle Northshore from May 2022 to April 2023. FY2025's surge partly reflects the restart, so extrapolating $7/unit of earnings forward would be a mistake; the trailing multiple flatters a number that has repeatedly evaporated.
