Segment Reporting
The Company has one reportable segment. The majority of the Company's business consists of researching, developing and commercializing therapies for the treatment of patients with elevated LDL-C. The segment derives net product sales through sale of its NEXLETOL and NEXLIZET tablets to customers in the United States and through collaboration agreements with other third party companies to develop, manufacture and commercialize its products outside the United States. Net product sales were $115.7 million, $78.3 million and $55.9 million for the three years ended December 31, 2024, 2023, and 2022, respectively. Collaboration revenue, which includes milestone payments, royalty revenues and sales of the Company's tablets to its collaboration partners, were $216.6 million, $38.0 million and $19.6 million for the three years ended December 31, 2024, 2023, and 2022, respectively. During the year ended December 31, 2024, collaboration revenue was primarily derived in Europe and Japan from the Company's partners DSE and Otsuka. The Company manages the business activities on a consolidated basis. The accounting policies of the segment are the same as those described in Note 2.

The Company's chief operating decision maker is the Chief Executive Officer, or CODM. The CODM assesses the performance of the Company and decides how to allocate resources based on revenues and net income (loss), which is reported on the statements of operations. The chief operating decision maker also assesses performance by reviewing net cash provided by (used in) operating expenses, which is reported on the statements of cash flows. The measure of segment assets is reported on the balance sheets as total assets. The chief operating decision maker also reviews cash and cash equivalents. A significant component of the CODM's decision-making process is to ensure a balanced investment in research and development, as well as commercial activities to drive near-term success and sustain for the long term.

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.
