Forward-looking statements include, without limitation, all matters that are not historical facts. Examples of forward-looking statements include, among others, statements we make regarding operating performance, events, or developments that we expect or anticipate will occur in the future, including statements relating to our outlook, revenue growth, earnings, earnings-per-sharegrowth, and similar projections, and the pending acquisition of Paycor. Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are based only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements relate to the future, they are subject to known and unknown uncertainties, risks, changes in circumstances, and other factors that are difficult to predict, many of which are outside our control. Our actual performance and outcomes, including without limitation, our actual results and financial condition, may differ materially from those indicated in or suggested by the forward-looking statements.

| • |     | the failure of third-party service providers to perform their functions; |

| • |     | the possibility that we may be exposed to additional risks related to our                
 co-employment relationship with our professional employer organization (“PEO”) business; |

| • |     | changes in health insurance and workers’ compensation insurance rates and underlying claim trends; |

| • |     | risks related to acquisitions and the integration of the businesses we
