Metallus Inc. Segments Disclosure

Note 3 - Segment Information

We conduct our business activities and report financial results as one business segment. The presentation of financial results as one reportable segment is consistent with the way the Company operates its business and is consistent with the manner in which the Chief Operating Decision Maker ("CODM") evaluates performance and makes resource and operating decisions for the business as described above. Our CODM is our Chief Executive Officer. Furthermore, the Company notes that monitoring financial results as one reportable segment helps the CODM manage costs on a consolidated basis, consistent with the integrated nature of the operations. The CODM uses Net Income (Loss), as reported on our Consolidated Statements of Operations, in evaluating performance of the Company and determining how to allocate resources of the Company as a whole. As the CODM evaluates performance on a consolidated basis, all required financial segment information is included in our consolidated financial statements.
