It is unclear how customers are notified that these performance obligations have been fulfilled. Clinical Testing, page 166 20. So that we may better understand your business, please revise to explain your responsibilities (if any) for finding a replacement patient or issuing a refund in the event that a patient you matched to a clinical trial decides not to proceed with (or unenrolls from) a clinical trial. Please also clarify if the Company is obligated to identify a specific number of potential clinical trial candidates or enroll a certain number of patients into clinical trials over a given period.

Please refer to ASC 606-10-55-36 through 55- 40. 27. You disclose on page 110 that, for the genomics product offering, costs associated with performing your tests are recorded at the time of report delivery. This seems inconsistent with disclosures on page F-15 indicating that costs are recorded as the tests are processed. Please revise as appropriate to correct this apparent discrepancy. If costs are recorded at the time of report delivery, please explain to us the basis for this policy and describe to us Eric Lefkofsky FirstName LastNameEric Lefkofsky Tempus Labs, Inc. Comapany 30, September NameTempus 2021 Labs, Inc. September Page 7 30, 2021 Page 7 FirstName LastName the typical time delay between processing of tests and report delivery.
