       Dear Douglas S. Aron:

       Form 10-K for Fiscal Year Ended December 31, 2023

       Management's Discussion and Analysis of Financial Condition and Results
of Operations
       Non-GAAP Financial Measures, page 39

   1.                                                   We note you present
"Gross Margin" as a non-GAAP measure and define it as total
                                                        revenue less cost of
sales (excluding depreciation and amortization). We also note that
                                                        you reconcile this
measure to net income. Please revise your reconciliation of this non-
                                                        GAAP measure to gross
margin as defined by GAAP, the most directly comparable
                                                        GAAP measure in
accordance with Item 10(e)(1)(i)(B) of Regulation S-K. If you do not
                                                        believe gross margin
that includes depreciation and amortization is the most directly
                                                        comparable GAAP
measure, please tell us why in your response. In addition, retitle this
                                                        measure throughout your
filings, including similar segment measures mentioned in Note
                                                        29 and information
provided in your press releases, to avoid confusion with the GAAP
                                                        measure of gross
margin.

Form 8-K filed May 1, 2024

Exhibit 99.1 - Press release dated April 30, 2024, announcing Archrock, Inc.'s
results of
operations for the quarter ended March 31, 2024
Reconciliation of Net Cash Flows Provided By Operating Activities to Free Cash
Flow and Free
Cash Flow After Dividend, page 8

2.       We note you define free cash flow as net cash provided by (used for)
operating activities
         plus net cash provided by (used in) investing activities which differs
from the
         typical calculation of this measure (i.e., cash flows from operations
less capital
         expenditures). In future filings, please revise the titles of your
non-GAAP measures "free
         cash flow" and "free cash flow after dividend" to alternative titles
in order to avoid
         potential confusion. Refer to Question 102.07 of the SEC Staff's
Compliance
         & Disclosure Interpretations on Non-GAAP Financial Measures.
        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.

       Please contact Joanna Lam at 202-551-3476 or Craig Arakawa at
