It remains unclear on what basis you are making these projections both for the increases in your flex offering and ancillary services and the projected increases in contribution margin. Please revise to disclose the material assumptions underlying the proportionate increase in Flex revenues and their associated higher margins. For example, what assumptions--other than the Robert D. Reid Supernova Partners Acquisition Company, Inc. July 28, 2021 Page 2 percentage of revenues in an unspecified time period--support the Flex contribution margins? What level of Flex revenues and other revenues are assumed for the 6%-8% margins, and what is the basis for such assumptions? Please advise us if the board of directors considered the illustrative case in its decision making and, if so, what time period it assumed Offerpad would achieve this performance.
