14. Segment Reporting

The Company operates and manages its business as one reportable operating segment, which is the business of developing pathogen-specific bacteriophage therapeutics for the treatment of antibiotic-resistant and difficult-to-treat acute and chronic bacterial infections using its proprietary bacteriophage-based technology. The determination of a single business segment is consistent with the consolidated financial information regularly provided to the Company’s chief operating decision maker (“CODM”). The Company’s CODM is its Chief Executive Officer, who reviews financial information on an aggregate basis for purposes of assessing performance, making operating decisions, allocating resources and evaluating financial performance. The Company maintains 99.5% of its $12.6 million property and equipment, net within the United States.
