Spok (SPOK) sells primarily to other companies and organizations, not directly to individuals. Its customer base consists predominantly of healthcare providers and institutions.

Due to the diversified nature of its client base, Spok does not publicly disclose the names of specific major customer companies. According to its annual reports (e.g., 2023 Form 10-K), no single customer accounts for more than 10% of its consolidated revenue, which would typically trigger a disclosure requirement for major customers. Therefore, instead of listing specific company names, the major categories of organizations that Spok serves are:

• Hospitals and Large Healthcare Systems: This category represents Spok's core market, including individual acute care hospitals, multi-hospital systems, and integrated delivery networks (IDNs) that utilize Spok's critical communication and care coordination platforms.
• Government and Military Healthcare Facilities: This includes medical facilities operated by government entities, such as Veterans Affairs (VA) hospitals, military medical centers, and other public health organizations that require secure and efficient communication solutions for their operations.
