Note 19. Business Segment Information
We operate our business as a single segment engaged in the development, manufacturing, marketing and sales of animal health products for both pets and farm animals. Consistent with our operational structure, our Chief Executive Officer (CEO), as the chief operating decision maker, makes resource allocation and business process decisions globally across our consolidated business. Strategic and resource allocation decisions are managed globally, with global functional leaders responsible for determining significant costs and investments and with regional leaders responsible for overseeing the execution of our global strategy. Managing and allocating resources at the global corporate level enables our CEO to assess the overall level of resources available and how to best deploy these resources across functions, product types, regional commercial organizations and R&D projects in line with our overarching long-term, corporate-wide strategic goals, rather than on a product or geographic basis. Consistent with this decision-making process, our CEO considers consolidated net income (loss), which is our single segment’s principal measure of segment profit and loss, when evaluating performance. Our CEO also considers these measures, as well as other factors, such as an assessment of a new product’s future market potential, when determining how to allocate company-wide resources.
Significant segment expenses are amounts that are regularly provided to our CEO and included in consolidated net income (loss), our primary measure of our single segment’s profit or loss. Our CEO regularly reviews reported consolidated revenue, gross profit, other significant segment expenses and consolidated net income (loss), in addition to forecasted revenue, significant segment expenses and net income (loss) amounts for future periods. A summary of our consolidated net (loss) income for the years ended December 31, is as follows, including the significant segment expenses provided to and regularly reviewed by our CEO, as well as other expenses, which are included in consolidated net (loss) income, but are not regularly provided to and/or reviewed by our CEO:

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.
