We rely extensively on information technology systems, some of which are managed or provided by third-party service providers, to collect, analyze, process, store, manage, transmit and protect key business processes, transactions and data, such as sales data, customer data, employee data, demand forecasting, merchandise ordering, inventory replenishment, supply chain management, payment processing, order fulfillment and more. Delays in the maintenance, updates, upgrading, or patching of these systems, applications or processes could adversely impact their effectiveness or could expose us to security and other risks. Our systems and the third-party systems with which we interact are subject to damage, failure or interruption due to various reasons such as: power or other critical infrastructure outages, facility damage, physical theft, telecommunications failures, malware, security incidents, malicious cyber-attacks, including the use of malicious codes, worms, phishing, spyware, denial of service attacks and ransomware, natural disasters and catastrophic events, inadequate or ineffective redundancy measures; and design or usage errors by AutoZoners, contractors or third-party service providers. Although we seek to effectively maintain and safeguard our systems and our data and we seek to ensure our third-party service providers effectively maintain and safeguard their systems and our data, such efforts are not always successful. As a result, we or our service providers have experienced and are likely to again experience one or more errors, interruptions, delays or cessations of service impacting the integrity or availability of our information technology infrastructure. While such incidents have not been material to date, any future incident could significantly disrupt our operations and key business processes, result in the impairment or loss of critical data, be costly and resource-intensive to remedy; harm our reputation and relationship with customers, AutoZoners, vendors and other stakeholders; and have a material adverse impact on our business and operating results.
In addition, our information technology systems, infrastructure and personnel require substantial investments, such as replacing existing systems, some of which are older, legacy systems that are less flexible and efficient, with successor systems; making changes to existing systems, including the migration of applications to the cloud; maintaining or enhancing legacy systems that are not currently being replaced; or designing or cost-effectively acquiring and implementing new systems with new functionality. These efforts can result in significant potential risks, including failure of the systems to operate as designed, potential loss or corruption of data, cost overruns, or implementation delays or errors, and may result in operational challenges, security control failures, reputational harm, and increased costs that could adversely affect our business operations and results of operations.
