Metallus Inc. (MTUS) stock intrinsic value fair value estimate & owner earnings analysis

Metallus Inc. (formerly TimkenSteel) makes special bar quality alloy steel, sold as bars, seamless mechanical tubes and billets, plus some finished components. About 330 customers in industrial, automotive, aerospace and defense, and energy markets purchase it; one customer was 10.6% of 2025 sales of $1,158 million, and about 90% of sales went to U.S. customers. Prices move with scrap and alloy costs through surcharges, so profits swing with steel demand and volumes. How we measured earning power. We start from cash generated by operations, remove the swings from receivables, inventory, payables and accruals, and then subtract stock compensation and the capital spending needed just to keep the mills running. Pension contributions are left in, because they are real cash the company has to pay. Two things shape the result. First, in 2024 and 2025 the company spent heavily on two new furnaces funded by a $99.75 million U.S. Army agreement to raise munitions steel output ($8.0 million of spending in 2024, $81.3 million in 2025); we treat that spending as expansion, not upkeep. Second, the Army money is reported as investing cash, not operating cash, so it does not flatter our figure. The record, per diluted share, 2017 to 2025: $1.16, $1.53, $(0.90), $0.01, $3.73, $2.03, $2.41, $0.03, $(0.28). It is a cyclical business: a 2021 peak, a good 2022 and 2023, then two very weak years. In 2024 volumes fell (sales down from $1,362 million to $1,084 million) and pension contributions were $45.5 million; in 2025 pension contributions rose to about $62 million and cash was tied up in working capital and capital spending. We use the median of the whole nine-year span, $1.16 per share, so the level is neither the 2021 peak nor the 2024 to 2025 trough. Earlier years are still the same mills and products, so we include them. Growth check. Owner earnings per share fell from $0.03 in 2024 to $(0.28) in 2025, and the base case does not assume any growth from the $1.16 level. What supports returning to that level is specific: the company expects pension contributions of about $27 million in 2026 versus $62 million in 2025, roughly $0.80 a share of relief; the pension shortfall shrank from $140.5 million to $91.7 million during 2025; and in the first half of 2026 sales were $649 million versus $585 million and net income $14.3 million versus $5.0 million. Against that, first-half 2026 operating cash flow was negative $14.1 million as working capital built again, and one half-year is not enough to move the level. We left out any gain from the Army furnaces: the agreement funds equipment, not a contracted volume of sales, and the earnings from it are not yet evidenced. Base case, $16.0 per share. Owner earnings stay flat at $1.16 per share for 30 years, discounted at 6%. No growth is credited: steel demand, share gains and the new munitions capacity are not secured. The 30-year horizon reflects that the mills, maintained by the capital spending already deducted, have operated through several cycles, while nothing named supports value much beyond that. Bear case, $3.4 per share. Owner earnings stay near $0.30 per share for 20 years, a little above the weak 2019, 2020, 2024 and 2025 results (four of the nine years came in at $0.03 or below). Named pressures: imports and changing tariff rules on steel and derivative products are disclosed as risks; the pension is still $91.7 million underfunded, with postretirement benefits another $29.7 million; and 2023 to 2024 non-Army capital spending of $50 to $56 million a year shows upkeep costs can run high. Bull case, $27.5 per share. Owner earnings of $2.00 per share, in line with 2022 ($2.03) and 2023 ($2.41), for 30 years. This is what happens if volumes and pricing hold at recent good-year levels with pension contributions normalized. We do not use the 2021 peak of $3.73. Balance sheet. At year-end 2025 the company had $156.7 million in cash, an undrawn revolving credit line (maturing September 2027), and had repaid its remaining convertible notes in 2025. Because owner earnings already reflect interest and pension cash paid, we neither add the cash nor deduct debt; leverage is not the main risk here, cyclicality and pension are. The 2026 capital plan is about $70 million, of which about $35 million is partly funded by the U.S. government; about $14 million of the $99.75 million agreement had not been received at year-end 2025. What would make this wrong. If 2024 and 2025 reflect a permanently lower earning power (heavier upkeep spending or lasting import pressure) rather than a trough, the base case is too high and the bear case is closer. If the Army-funded furnaces lead to sustained new defense volume, the bull case is conservative. Some pieces we could not reconcile from the filings: the exact timing of the remaining Army funding, and how much of 2026 capital spending is upkeep versus expansion. Margin-of-safety price. Given a cyclical business with two near-zero years, a pension shortfall and a wide gap between the bear and base cases, the margin-of-safety price is set at roughly half of the base value, or about $8 per share.
