Segment and Geographic Information
We have two reportable segments organized according to our products and services: Medical Devices and Preservation Services. The Medical Devices segment includes external revenues from product sales of aortic stent grafts, On-X, surgical sealants, and other product revenues. Aortic stent grafts include aortic arch stent grafts, abdominal stent grafts, and synthetic vascular grafts. Aortic arch stent grafts include our E-vita® Open NEO, E-vita Open Plus, Arcevo LSA, AMDSTM, NEXUS ONETM, NEXUS DUOTM, NEXUS TRETM, E-vita Thoracic 3G. Abdominal stent grafts include our E-xtra Design Engineering, E-nsideTM, ArtivexTM, E-tegraTM, E-ventusTM BX, TuvaTM BX, and E-liacTM products. Surgical sealants include BioGlue® Surgical Adhesive products. The Preservation Services segment includes external services revenues from the preservation of cardiac and vascular tissues. There are no intersegment revenues.
Our Chief Operating Decision Maker (“CODM”) is the Company’s Chairman, President, and CEO. The CODM reviews financial information to assess segment performance and determine how to allocate resources across segments.
The primary measure of segment performance, as assessed by our CODM, is segment gross margin or net external revenues less cost of products and preservation services. The CODM regularly reviews these costs, recognizing them as significant segment expenses. We do not segregate assets by segment; therefore, asset information is excluded from the segment disclosures below.

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.
