         such benefits in a clear and direct manner.

3.       We note your revisions in response to prior comment 13 regarding your
         Please expand your disclosure to identify other key assumptions beyond
the three you
         identify. For example, we note you reference "increased demand and
rate of sales orders;"
         an "increase of expected average sales price" and "an increase in
customer subscriptions"
         among other disclosures.

4.       We refer you to the third paragraph on page 170. Your disclosure
refers to the objectives
         of the preparation requirements under the legacy pro forma rules and
are no longer
         applicable under the amended rules. Please revise your disclosures
accordingly. Refer
         to Release No. 33-10786.
5.       Your pro forma income statements appear to be prepared assuming that
the conversion of
         Xos    notes payable occurred on January 1, 2020. Please revise to
include this information
         in the introductory paragraph, or explain how you believe adjustments
(CC), (DD), and
         (EE) comply with the requirements in Article 11 of Regulation S-X and
Release No. 33-

6.       Your response to prior comment 17 indicates that you revised your
presentation to
         reclassify the transaction fees from APIC to accumulated deficit. As
the business
         combination will be accounted for as a reverse recapitalization
transaction, qualifying
         transaction costs incurred by the target company should be charged
directly to equity. In
         this regard, please revise your presentation in the pro forma balance
sheet to reflect the
         adjustment for transaction costs against APIC. Refer to SAB Topic 5.A.
         revise the related disclosure in the notes to the pro forma financial
statement to be
         consistent with the presentation reflected in the pro forma balance
sheet (Note C).

7.       Please revise to reflect the recognized loss on extinguishment of
convertible debt in your
         pro forma income statement for the year ended December 31, 2020, if
prepared assuming
         that the conversion of Xos    notes payable occurred on January 1,
        We remind you that the company and its management are responsible for
the accuracy
and adequacy of their disclosures, notwithstanding any review, comments, action
or absence of
action by the staff.
