We noted your discussion and presentation of Adjusted EBITDA in Exhibit 99.2 to Form 8-K furnished on February 22, 2024, without the discussion and the presentation of the corresponding directly comparable GAAP measure (i.e., GAAP Net Loss). Your presentation appears to give greater prominence to the non-GAAP measure and does not comply with Item 10(e)(1)(i)(A) of Regulation S-K and Question 102.10 of the Division's Compliance & Disclosure Interpretations on Non- GAAP Financial Measures which requires you to present the most directly comparable GAAP measure with equal or greater prominence. Please revise your future presentations to comply. Form 10-Q filed on November 6, 2023 Key Financial Metrics, page 44 2.

We note that you present the total adjusted gross profit and total adjusted gross margin as your non-GAAP measures without the presentation of the corresponding directly comparable GAAP measures. Refer to Question 102.10 and 104.04 of the Compliance and Disclosure Interpretations on Non-GAAP Financial Measures. Please revise future filings to include a "fully loaded" total GAAP gross profit and margin or remove these measures.

Notes to the Consolidated Financial Statements Leases, page 103 4. You disclose that your leases do not provide an implicit rate and you use an estimated incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. Please revise in future disclosures to clarify whether the rates implicit in your leases are readily determinable and if that is the basis for using your incremental borrowing rate as the discount rate for your leases. Refer to Rate Implicit in the Lease defined in ASC 842-20-20. Note 9 - Leases Operating leases, page 112 5. Please revise future filings to include the disclosures outlined in ASC 842-20-50-4 in a table or a format that properly conveys this information. Please indicate whether your leases contain variable costs. In addition, please clarify why your footnote 5 - Property and Equipment references amortization of assets recorded under a capital lease. In this regard, we note your disclosure on page 103 that states that "[y]our leasing commitments are classified either as operating leases or otherwise qualify as short-term leases with lease terms of 12 months or less". Please clarify whether you do have finance leases under ASC 842. Clarify how you are presenting the reduction in the carrying amount of ROU operating lease assets in your consolidated statements of cash flows. Jason Alger Health Catalyst, Inc.
