2 Safe Harbor Statement Statements contained herein or in prior press releases which are not historical fact, such as statements regarding our future operating and financial performance, are forward-looking statements for purposes of the safe harbor provisions under the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties that may cause our actual results to be materially different from the future results expressed or implied by such forward-looking statements. Factors that could cause actual results to differ materially from those expectations include, but are not limited to, our ability to manage wireless network rationalization to lower our costs without causing disruption of service to our customers; our ability to retain key management personnel and to attract and retain talent within the organization; the productivity of our sales organization and our ability to deliver effective customer support; our ability to identify potential acquisitions, finance, consummate and successfully integrate such acquisitions, and achieve the expected benefits of such acquisitions; economic conditions, such as recessionary economic cycles, the impact of trade disputes, tariffs and other trade protection measures, higher interest rates, inflation and higher levels of unemployment; risks related to our overall business strategy, including maximizing revenue and cash generation from our established businesses and returning capital to stockholders through dividends and repurchases of shares of our common stock; competition for our services and products from new technologies or those offered and/or developed from firms that are substantially larger and have much greater financial and human capital resources; continuing decline in the number of paging units we have in service with customers, commensurate with a continuing decline in our wireless revenue; our ability to address changing market conditions with new or revised software solutions; undetected defects, bugs, or security vulnerabilities in our products; our dependence on the United States healthcare industry; long sales cycle of our software solutions and services; our reliance on third-party vendors to supply us with wireless paging equipment; our ability to maintain successful relationships with our channel partners; our ability to protect our rights in intellectual property that we own and develop and the potential for material litigation claiming intellectual property infringement by us; our use of open source software, third-party software and other intellectual property; our reliance on data centers and other computer systems, hardware, software and satellite networks and telecommunications systems infrastructure (collectively, "IT Systems") and technologies provided by third parties, and technology systems and electronic networks supplied and managed by third parties; cyberattacks, data breaches, system disruptions or other compromises to our or our critical third parties’ IT Systems, data, products or services; our ability to realize the benefits associated with our deferred income tax assets; future impairments of our long- lived assets or goodwill; risks related to data privacy and protection-related laws and regulation; and our ability to manage changes related to regulation, including laws and regulations affecting hospitals and the healthcare industry generally, as well as other risks described from time to time in our periodic reports and other filings with the Securities and Exchange Commission. Although Spok believes the expectations reflected in the forward-looking statements are based on reasonable assumptions, it can give no assurance that its expectations will be attained. Spok disclaims any intent or obligation to update any forward-looking statements.
