Segment Information

The Company’s CODM is Worthington Steel’s CEO. The Company has determined that it has only one operating segment and therefore one reportable segment after considering several sources of information, including the Company’s internal organizational structure, the basis on which budgets and forecasts are prepared, the financial information that the Company’s CODM reviews in evaluating company performance and determining how resources should be allocated, and how the Company releases information to the public and analysts. The CODM manages all business activities on a consolidated basis, and as a result, the Company has concluded that there is only one operating segment and therefore one reportable segment.

The Company’s one reportable segment serves its customers primarily by processing flat-rolled steel coils, which are sourced primarily from various North American steel mills, into the precise type, thickness, length, width, shape, and surface quality required by customer specifications. The Company generates a substantial percentage of its revenue from selling steel on a direct basis, whereby it is exposed to the risk and rewards of ownership of the material while in its possession. Additionally, the Company toll processes steel under a fee for service arrangement whereby it processes customer-owned material.

As the one reportable segment is managed on a consolidated basis, the measure of segment profit or loss is consolidated net earnings. The CODM uses consolidated net earnings to assess the performance of the Company’s one segment and decide how and where to allocate resources and reinvest profits into the business in areas such as capital expenditures, business and/or asset acquisitions, investments in market share expansion with our existing and potential new customers, talent, technology, the repurchase of the Company’s common shares, and/or the payment of dividends. Net earnings and components of net earnings are used to monitor actual performance and are compared to budgeted and forecasted results to assess the performance of the Company’s one reportable segment, set targets, and establish management’s incentive compensation. The measure of consolidated segment assets is reported on the balance sheets as total assets.

The Company regularly provides the CODM a reporting package that is structured similar to the statement of earnings, and the CODM reviews consolidated net earnings (loss) as a key performance measure of profit (loss) for the Company’s single reportable segment and reviews significant expenses on a consolidated basis consistent with the presentation on the consolidated statements of earnings, with the exception of cost of goods sold, which is further disaggregated. The CODM’s review is focused on the consolidated results for the Company.

The following table presents the significant expenses that are regularly provided to the CODM for the one reportable segment and the required disclosable amounts that are included in consolidated net earnings for the periods presented:
