Corcentric's quarterly results may fluctuate significantly and may not fully reflect the underlying performance of Corcentric's business. + Corcentric's risk management efforts may not be effective to prevent fraudulent activities by its customers, employees or other third parties, which could expose Corcentric to material financial losses and liability and otherwise harm its business. Corcentric facilitates the transfer of customer funds daily, and is subject to the risk of errors, which could result in financial losses, damage to its reputation, or loss of trust in its brand, which would harm its business and financial results. Corcentric's business depends, in part, on Corcentric's partnerships with financial institutions, third party service providers, processing providers and other financial services suppliers. If any of Corcentric's agreements with such financial institutions, third party service providers, processing providers, or financial services providers are terminated, Corcentric could experience service interruptions + Integrating acquisitions may be time-consuming and create costs that could reduce Corcentric's net income and cash flows.

Corcentric is subject to governmental regulation and other legal obligations, particularly those related to privacy, data protection and information security, and its actual or perceived failure to comply with such obligations could harm its business, by resulting in litigation, fines, penalties or adverse publicity and reputational damage that may negatively affect the value of its business and decrease the price of new Corcentric Common Stock. Compliance with such laws could also result in additional costs and liabilities to Corcentric or inhibit sales of its products. corcentric 46
