   1.                                                   We note your response
to our prior comment one and your restored disclosure. Please
                                                        expand your results of
operations discussion for nine months ended December 31, 2023,
                                                        to discuss and analyze
how the acquired solutions with relatively higher cost of revenues
                                                        impacted the change in
total cost of revenue as a percentage of reported revenue. Also,
                                                        since your recent
acquisitions    primarily generate volume-based revenue, with a higher
                                                        cost of revenue
relative to the cost of revenue for other Waystar solutions,    disclose if
this
                                                        is a known trend that
is reasonably likely to have a favorable or unfavorable impact on
                                                        your cost of revenues
and income from continuing operations. We refer to guidance in
                                                        Item 303(b)(2)(ii) of
Regulation S-K.
   2.                                                   Regarding your segments
