These statements are not guarantees of future performance nor promises that goals or targets will be met, and involve a number of risks, uncertainties and other factors that are difficult to predict and could cause actual results to differ materially from those expressed or implied. Many of the following risks, uncertainties and other factors identified below may be amplified by conflict in the Middle East, as well as any escalation or expansion of economic disruption or the conflict’s current scope. These risks include, without limitation, risks that: Accenture and GLOBAL SECURITY EXPERTS will not be able to close the transaction in the time period anticipated, or at all, which is dependent on the parties’ ability to satisfy certain closing conditions; the transaction might not achieve the anticipated benefits for Accenture; Accenture’s results of operations have been, and may in the future be, adversely affected by volatile, negative or uncertain economic and geopolitical conditions and the effects of these conditions on the company’s clients’ businesses and levels of business activity; Accenture’s business depends on generating and maintaining client demand for the company’s solutions and services including through the adaptation and expansion of its solutions and services in response to ongoing changes in technology and offerings, and a significant reduction in such demand or an inability to respond to the evolving technological environment could materially affect the company’s results of operations; risks and uncertainties related to the development and use of AI, including advanced AI, could harm the company’s business, damage its reputation or give rise to legal or regulatory action; if Accenture is unable to match people and their skills with client demand around the world and attract and retain professionals with strong leadership skills, the company’s business, the utilization rate of the company’s professionals and the company’s results of operations may be materially adversely affected; Accenture faces legal, reputational and financial risks from any failure to protect client and/or company data from security incidents or cyberattacks; the markets in which Accenture operates are highly competitive, and Accenture might not be able to compete effectively; if Accenture does not successfully manage and develop its relationships with its ecosystem partners or fails to anticipate and establish new alliances in new technologies, the company’s results of operations could be adversely affected; Accenture’s ability to attract and retain business and employees may depend on its reputation in the marketplace; Accenture’s profitability could materially suffer due to pricing pressure, if the company is unable to remain competitive, if its cost-management strategies are unsuccessful or if it experiences delivery inefficiencies or fail to satisfy certain agreed-upon targets or specific service levels; changes in Accenture’s level of taxes, as well as audits, investigations and tax proceedings, or changes in tax laws or in their interpretation or enforcement, could have a material adverse effect on the company’s effective tax rate, results of operations, cash flows and financial condition; Accenture’s results of operations could be materially adversely affected by fluctuations in foreign currency exchange rates; Accenture’s debt obligations could adversely affect its business and financial condition; as a result of Accenture’s geographically diverse operations and strategy to continue to grow in key markets around the world, the company is more susceptible to certain risks; if Accenture is unable to manage the organizational challenges associated with its size, the company might be unable to achieve its business objectives; Accenture might not be successful at acquiring, investing in or integrating businesses, entering into joint ventures or divesting businesses; Accenture’s business could be materially adversely affected if the company incurs legal liability; Accenture’s work with government clients exposes the company to additional risks inherent in the government contracting environment; Accenture’s global operations expose the company to numerous and sometimes conflicting legal and regulatory requirements; if Accenture is unable to protect or enforce its intellectual property rights or if Accenture’s solutions or services infringe upon the intellectual property rights of others or the company loses its ability to utilize the intellectual property of others, its business could be adversely affected; Accenture may be subject to criticism and negative publicity related to its incorporation in Ireland; as well as the risks, uncertainties and other factors discussed under the “Risk Factors” heading in Accenture plc’s most recent Annual Report on Form 10-K and other documents filed with or furnished to the Securities and Exchange Commission.
