The Company operates in highly competitive markets that are subject to rapid change, including, in particular, changes in customer preferences and changes and advances in relevant technologies. There are substantial uncertainties associated with the Company's efforts to develop successful trade publishing, educational, and media products and services, including digital products and services, for its customers, as well as to adapt its print and other materials to new digital technologies, such as the internet cloud technologies, tablets, mobile and other devices and school-based technologies and uncertainties involving the use of artificial intelligence in connection with the foregoing. The Company makes significant investments in new products and services that may not be profitable, or whose profitability may be significantly lower than the Company anticipates or has experienced historically. In particular, in the context of the Company's current focus on key digital opportunities, the markets are continuing to develop and the Company may be unsuccessful in establishing itself as a significant factor in any relevant market segment which does develop. Many aspects of markets which could develop for children and schools, such as the nature of the relevant software and devices or hardware, the size of the market, relevant methods of delivery and relevant content, as well as pricing models, are still evolving and will, most likely, be subject to change on a recurring basis until a pattern develops and becomes more defined. This could specifically impact the Company's ability to execute on a digital and print literacy solution, which requires a multi-year investment, through internal development, third party providers and/or acquisitions. In addition, the Company faces market risks associated with systems development and service delivery in its evolving school ordering and ecommerce businesses, as well as in responding to changes in how schools plan to utilize technology for virtual or remote learning and the potential impact on the demand for printed materials in schools.
