Business	Business — Spōk Holdings, Inc. and its subsidiaries (collectively, “Spok” or the “Company”) deliver smart, reliable solutions to help protect the health, well-being, and safety of people around the globe. Organizations worldwide rely on Spok for workflow improvement, secure texting, paging services, contact center optimization, and public safety response. The Company continues to enhance the way people communicate in critical situations. Critical communications occur when minutes and seconds matter, and lives are on the line. For example, Spok helps doctors reach other clinicians quickly to treat patients and supports 9-1-1 operators who dispatch assistance for callers in distress. People who improve and save lives rely upon technology to communicate when seconds matter, which is why our customers choose Spok. Our diverse product offerings help them communicate safely, securely, and efficiently when fast response is key, no matter what situations they face. We work with organizations worldwide in a variety of industries, including healthcare, public safety, government, hospitality, large enterprise, and education. Each month, we deliver millions of messages across a host of devices - from smartphones and pagers, to tablets and Wi-Fi enabled devices - so information is delivered when and where it matters most. Healthcare organizations represent our largest customer base. Today, these organizations are facing unprecedented challenges. In the U.S., many healthcare organizations are dealing with reduced reimbursements, compliance requirements, and other financial pressures. More than ever, staff cannot waste time looking for information, people, supplies, or open beds. Notifications must go to the right people at the right time. Doctors need a way to find one another for important conversations, and automated information sharing from clinical systems needs to be embraced for efficient care and interaction. Organizations require plans for what tools are supported, how information is encrypted in messages, how to remove sensitive information from lost or stolen smartphones, and the best way to manage access to web directories and on-call schedules. Technology can effectively enable hospitals to address these challenges. Improved communications through technology can have a domino effect that impacts nearly every area of the hospital, including the financial challenges. Reimbursements are directly tied to patient satisfactions scores, which in turn are affected by improved response to patient requests as well as speedier discharge procedures. Improving communications can have a positive impact on these factors. Spok spans the patient care continuum within the hospital, providing communication solutions for all those who are responsible directly or indirectly for patient care. From clinical alarm/alert management technology to on-call schedules and preferred devices, to mobile devices of all types, to the contact center, Spok technology extends throughout the reach of patient care. Spok products are also used in the public safety sectors. Our customers seek advanced technology to respond to emergency calls received via mobile devices. Estimates are that as much as 70 percent of 9-1-1 calls are made from cell phones. 9-1-1 callers also want to use text messaging and video when communicating with public safety answering points about emergencies. We have recognized this as the future and our strategic direction. The way public safety organizations handle response is truly changing, and the technology capabilities that can address these changes are known as next-generation 9-1-1 ("NG9-1-1"). Our customers want to be able to track down a 9-1-1 caller’s exact location-even if the caller is unable to speak for any reason-and be able to handle incoming videos at the 9-1-1 call center. We also have to support mobile first responders with smartphone solutions like traceable text messaging and reliable paging even during disasters when cellular service is down. Mobile solutions are critical for continuity of response and protecting safety. In recent years, smartphones and apps have become an integral part of our daily lives, and Spok customers rely on us for our secure texting app. However, even as usage of smartphones, tablets, and wearable devices grows, it is important to recognize that paging's survivable architecture and cost effectiveness retain clear advantages over cellular service in many instances. Paging has been essential to workflow and emergency response for well over 30 years. And the value of paging remains high today. If anything, the proliferation of smartphones is making the redundancy of paging even more critical to the medical and public safety sectors. In an emergency, cellular networks can become congested or a local cellular site can be down due to power loss, preventing a message from being received on a timely basis. In fact, emergencies of all sizes and scopes have indicated that no single wireless technology should be relied upon exclusively, and having multiple options is the best way to ensure a message gets through. When critical communications matter, Spok delivers.
