3.       Please provide additional context regarding your revenue in 2020 and
the six months
         ended June 30, 2021. Disclose the portion of your revenue generated
from COVID-19
         testing for each period. Also disclose that you expect your COVID-19
revenue to
         decrease due to the expiration of your agreement with CVS in July 2021
and as the
         prevalence of COVID-19 subsides and as other COVID-19 testing
providers enter the
         market.
Our Three Product Lines, page 5

4.       Please disclose the percentage of revenue generated from each of the
three product lines.
         We note that the substantial majority of your total revenue is
generated from genomics
         and the revenue from Algo has not been significant.
Data, page 6

5.       Please revise your disclosures on pages 7-8 regarding the cohort
graphics as follows:
             Clarify the differences (if any) between sequencing revenue
presented here and
             genomics revenue as presented on the face of your financial
statements.
             Describe the limitation of these analyses. For example, revise to
explain the types of
             revenues and cost of revenues excluded from these analyses.
             Since you do not present any gross profit measures on the face of
your GAAP income
             statement, please remove references to the phrase "gross profit"
from these analyses.
             Revise the note below the 2020 Cohort table on page 8 to quantify
the cost of
             subsequent data revenue that is excluded from the cohort analysis
for each period
             presented.
             Make similar revisions as needed to the cohort analyses presented
on pages 105-106
             and 147-148.

Department of Health,
         including any termination provisions.

publications are a good
         indicator of success. We also note your disclosure on page 163
indicating that you have
         self-authored 29 of 41 total articles in which you have been
mentioned. Please revise your

for certain sequencers,
         reagents, blood tubes and other equipment, instruments and materials
that you use in your

We have identified a material weakness in our internal control over financial
reporting, page 74

9.       You state that you have taken steps to remediate the material weakness
in your internal
         controls by hiring a Chief Accounting Officer and other key technical
accounting and
         financial reporting roles to further develop and document your
accounting policies and
         financial reporting procedures, including ongoing senior management
review. You also
         state that you will continue to work to remediate this material
weakness by hiring
         additional qualified accounting and financial reporting personnel,
training existing
         personnel, and improving your accounting processes. Please disclose
how long you
         estimate it will take to complete your plans and any associated
material costs that you
         have incurred or expect to incur.

directors. Please
         disclose the percentage of his time that he devotes to the business of

         his other responsibilities as the co-founder and Executive Chairman of
the board of Pathos

Management's Discussion and Analysis of Financial Condition and Results of
Operations
Results of Operations, page 112

11.      You state that the increases in Genomics revenue in 2020 and the six
months ended June
         30, 2021 were attributable primarily to the increases in the number of
next generation
         sequencing clinical tests delivered. Please disclose the number of
clinical test that were
         delivered for each period presented.
Comparison of the Six Months Ended June 30, 2020 and 2021, page 112

12.      For all periods presented, please revise to provide greater context to
your discussion of
         changes in revenue between periods. For example, please revise to
quantify the extent to
         which increases are attributable to increases in prices or volume of
tests performed in the
         Genomics product category or the number of new subscription agreements
in the data and
         other product category. Please refer to Item 303(a)(3)(iii) of
Regulation S-K.
Cash Flows, page 117

13.      In order to provide investors with a better understanding of your
business as a whole,
         please revise your discussion of cash flows for all periods presented
so that the causes for
         changes in cash flows are addressed, rather than simply repeating the
numerical data
         contained in the consolidated financial statements. Please refer to

         303(a) of Regulation S-K.

Contractual Obligations and Commitments, page 118

14.      We note that the amount of total purchase obligations shown here is
not consistent with
         the amounts presented on page F-25. Please revise to clarify the
nature of the purchase
         obligations shown here and how the amounts presented were determined.
For example, to
         the extent that these represent obligations under data license
agreements, it is unclear if
         amounts presented include estimates for additional payments contingent
on the
         commercialization of data. Please also make any conforming changes, as
necessary, on
         page F-25.
Critical Accounting Policies and Estimates
Revenue Recognition, page 119

15.      You disclose on page 166 that you only received payment on
approximately 50% and
         48% of your clinical oncology NGS tests during 2019 and 2020. It is
unclear if you
         anticipated this level of reimbursement when you developed your
estimates of variable
         consideration. Please revise to discuss the significant judgements
made in the application
         of your revenue accounting policies and the likelihood of materially
different reported
         results if different assumptions or conditions were to prevail. Refer
to Item 303(a) of
         Regulation S-K, SEC Interpretive Release No. 33-8350 and SEC Release
No. 33-8040.
16.      We note from your disclosures on pages 34 and 181 that all claims
summitted to the Local
         MAC for NGS oncology tests performed for Medicare beneficiaries in
your Chicago lab
         after March 25, 2021 have been denied. We further note that this type
of testing
         represented 30% of your clinical testing volume as of June 30, 2021.
While you have
         begun the process of appealing these denials, it is unclear how you
accounted for these
         claims and how your financial statements have been impacted. Please
refer to SEC
         Release No. 33-8040, Item 303(a) of Regulation S-K and ASC
606-10-50-17.
         Please revise your disclosures here, in your MD&A and in your
financial statement
         footnotes, as applicable, to:
             Discuss any changes to your estimates of variable consideration.
             Quantify the amount of unpaid receivable balances as of June 30,
3021 related to
              these denied claims.
             Explain if and how you plan to pursue reimbursement from other
sources if your
              denial appeals are not successful.
             Quantify the amount of revenue recognized for NGS oncology tests
performed for
              Medicare beneficiaries in your Chicago laboratory after March 25,
2021.
             To the extent you continue to recognize revenue associated with
NGS oncology
              tests performed for Medicare beneficiaries in your Chicago
laboratory, tell us how
              you considered ASC 606-10-32-14.

data you acquire and/or
         ingest. Please explain if there are any goods or services you provide
to these entities in
         exchange for the data you receive. Please also revise to address what
happens to the data
         you have acquired if the providers who gave you access to data cease
doing business with
         the Company. For example, it is unclear if you retain rights to sell
and/or license the data
         acquired into perpetuity or only for a specific period of time.
Customer Facing Applications, page 132

18.      Please revise to more clearly explain the relationship between your
customer facing
         applications (Hub and Lens) and your three product lines (Genomics,
Data and Algos),
         including your primary Data products, Insights and Therapies.
Therapies, page 148

19.      Please revise to more fully describe the billing process for your
Therapies product. For
         example, your disclosures on page 119 and F-15 indicate that the
performance obligation
         is delivery of a notification of a matched patient for clinical trial
or enrollment of a patient
         in a clinical trial. 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.

require you to
         cover the initial setup costs for Data products. If material, please
revise to provide
         accounting policy disclosure for costs to obtain and/or fulfill
contracts. Please refer to
         ASC 340-40.
Concentration of Credit Risk, page F-12

22.      Please revise to disclose revenue and accounts receivable customer
concentrations as of
         and for the period ended June 30, 2021. For all periods presented,
please also disclose
         concentrations in revenue due to COVID-19 testing. We note your
disclosures on page
         145 that you have shifted resources away from COVID-19 testing and do
not expect the
         level of COVID-19 testing to be material to your business going
forward. Please refer to

Revenue Recognition, page F-14

23.      We note your disclosure on page 132 that you sometimes charge for
access to Lens when
         a customer is interested in either a broader integration or some form
of customization.
         Please tell us how you considered if access to Lens should be
considered a separate
         performance obligation within your Data and other product offering.
Please refer to ASC
         606-10-25-14 through 25-22.
24.      You disclose on page 146 that for your Insights offering, customers
pay either on a per file
         basis or through multi-year subscription agreements. You also indicate
that you have
         signed contracts with a total remaining contract value of $172 million
that you expect
         deliver to over the next several years. Please revise your revenue
recognition policy for
         data and other to describe the types of contracts available to
customers, to disclose the
         average length of your multi-year subscription agreements, and to
provide the disclosures
         required by ASC 606-10-50-13.
25.      On page 107, you disclose that through your Insights product, you
license libraries of de-
         identified data and provide a suite of analytical services. Please
tell us the nature of
         analytic services provided and explain how you determined those
services did not
         represent a separate performance obligation. Additionally, we note
your disclosure on
         page 146 that data profiles regularly update with clinical outcome and
response data over
         time. Please tell us and revise your filing as appropriate to explain
your process for
         providing license updates to customers, the specific features and
functionality that your
         updates and upgrades provide and how you account for those updates.
Please specifically
         address how you considered if those updates represent a distinct
performance obligation.
         Please refer to ASC 606-10-25-21.

Cost of Revenue, Genomics, page F-15

26.      You disclose on page F-15 that your cost of revenue, genomics includes
third-party
         laboratory costs. So that we may better understand your business,
please explain the
         nature of your contractual relationships with third-party
laboratories, including the types
         of services performed by these labs. Please tell us how you considered
the involvement of
         third party labs in determining if you were acting as a principal or
an agent in your
         contractual arrangements with customers. 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

classified as Research

technology
         expenses do not qualify as research and development costs under either
ASC 985-20-25 or
         730-10-25, please tell us how your policy of excluding technology
costs from cost of
         revenues and/or selling, general and administrative expenses complies
with Rule 5-
         03(b)(2) of Regulation S-K.

Platform services you
         use. Please also clarify the extent to which these notes require any
minimum principal
         and/or interest payments prior to the maturity date. We note
disclosure on page F-23 that
         your current liabilities include $15.5 million of interest payable as
of June 30, 2021 but it
         is unclear if these amounts pertain to your convertible promissory
notes.

33.      Please revise to clarify if the negative impacts to your business as a
result of COVID-
         19 were also minimal for the six months ended June 30, 2021.
Additionally, we note from
         your disclosure on page 22 that your COVID-19 testing agreement with
CVS expired in
         July 2021. Considering that this contract represented 24% of your
