13. Segment Information:
The segment information herein excludes the results of the divested Advanced Materials & Catalysts segment, which is reflected in discontinued operations as described in Note 4, for all periods presented.
Following the divestiture of the Advanced Materials & Catalysts segment, it was determined that the Company has one operating segment which represents one reportable segment under GAAP. The Company’s single reportable segment, Ecoservices, derives its revenue through the sale of virgin and regenerated sulfuric acid products and services.
The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer. The Company’s CODM evaluates the segment operating results for performance assessment and resource allocation purposes based upon entity-wide sales and expense information reported in the consolidated statements of (loss) income. The primary measure of segment profit is net income from continuing operations as reported in the consolidated statements of (loss) income. Significant segment expense categories evaluated by the CODM include cost of goods sold, selling, general and administrative expenses, and the other line items reported in the consolidated statements of (loss) income. As the Company has a single reportable segment, assets are reported in the consolidated balance sheets and capital expenditures are reported in the consolidated statements of cash flows.
The CODM evaluates entity-wide results to allocate resources (including employees, property and financial or capital resources) for the segment primarily in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a monthly basis when making decisions about allocating capital and personnel to the segment. The CODM also uses consolidated results to evaluate the return on assets of the segment in connection with performance evaluation and to inform the compensation for certain employees.

About Segments Disclosures

Segment disclosures break a company into its reportable operating units, revealing revenue, profit, and asset allocation that consolidated financial statements obscure. Under ASC 280, segments must match how the chief operating decision maker views the business, providing a window into internal management structure and resource allocation priorities.

Key signals: compare segment margins to identify which units drive profitability and which destroy value. Watch for changes in the number of reportable segments — segment aggregation or disaggregation often coincides with strategic shifts or attempts to obscure declining performance. Intersegment elimination patterns reveal internal pricing practices. The reconciliation between segment totals and consolidated figures exposes corporate overhead allocation and unallocated items. Geographic revenue concentration highlights regulatory and currency exposure. Compare segment-level capital expenditure against segment revenue to assess where management is investing for future growth versus harvesting existing assets.
