provide meaningful information about underlying trends in its business and operations and provide both management and investors a more complete understanding of the Company’s financial position and performance. Non-GAAP financial measures
should be viewed in addition to, and not as an alternative for, SPFI’s reported results prepared in accordance with GAAP. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or
as a substitute for analysis of the results or financial condition of the Company as reported under GAAP. 2 Numbers in this presentation may not sum due to rounding.
