Management Commentary and Outlook

“As the market continues to strengthen and execution by team Archrock remains excellent, we delivered a sequential increase in our contract operations revenue as well as our highest quarterly levels of operating horsepower growth and bookings for the year during the fourth quarter. We closed out 2021 generating positive net income and record annual free cash flow at the bottom of the cycle,” said Brad Childers, Archrock’s President and Chief Executive Officer. “More broadly, throughout this downturn, we’ve demonstrated the stability and cash generating power of our business, repaying $314 million in debt and returning $178 million to shareholders since the end of 2019.

“We also achieved several important technology milestones in 2021, completing the installation of expanded telematics across our fleet, launching a suite of leading-edge mobile tools for our field service technicians and migrating key support functions to our new cloud-based ERP system. These milestones reflect years of effort to radically transform our business to ensure our franchise is prepared for energy transition. With our optimized, standardized and digitized business, we are at an exciting inflection point. And, as we enter the multi-year upcycle in natural gas that we see ahead, we are invested in leveraging the strong foundation of our core compression business and evaluating complementary opportunities to help our customers decarbonize. 

“Looking at 2022 capital allocation, having completed nearly $250 million in strategic divestments over the last three years, together with the opportunity to invest in high-profit, large midstream compressors, our ability to drive higher-quality EBITDA growth is accelerating. Our commitment to strong returns and reducing our emissions footprint are driving our investment strategy as we grow prudently with our customers. As such, we expect approximately 25% of our growth capex budget to fund expansion of our electric motor-drive horsepower. Finally, we are confident that the strength of our cash flows will continue to fund our well-covered and competitive dividend and allow us to maintain a healthy balance sheet,” concluded Childers.

Fourth Quarter and Full Year 2021 Financial Results

Archrock’s fourth quarter 2021 net income of $6.0 million included a pre-tax non-cash long-lived and other asset impairment of $6.2 million, a pre-tax insurance settlement related to damages to facilities and compressors caused by Hurricane Ida of $2.8 million and pre-tax restructuring costs of $950,000. Archrock’s fourth quarter 2020 net income of $4.8 million included a pre-tax non-cash long-lived and other asset impairment of $7.4 million and pre-tax restructuring costs totaling $1.4 million.

Adjusted EBITDA for the fourth quarter of 2021 of $83.5 million included $0.7 million in net gains related to the sale of compression and other assets.

Contract Operations

For the fourth quarter of 2021, contract operations segment revenue totaled $159.5 million compared to $158.9 million in the third quarter of 2021 and $168.8 million in the fourth quarter of 2020. Gross margin was $99.0 million, compared to $97.6 million in the third quarter of 2021 and $110.2 million in the fourth quarter of 2020. This reflected a gross margin percentage of 62%, compared to 61% in the third quarter of 2021 and 65% in the prior year quarter.

The annual decline reflected the sale of 147,000 active horsepower as part of our ongoing fleet high-grading initiative. Utilization at the end of the fourth quarter of 2021 was 84%, compared to 82% at both the end of the third quarter of 2021 and the end of the fourth quarter of 2020.

Aftermarket Services

For the fourth quarter of 2021, aftermarket services segment revenue totaled $35.7 million, compared to $36.3 million in the third quarter of 2021 due to a seasonal slowdown. Fourth quarter 2021 aftermarket services revenue was up from $30.6 million in the fourth quarter of 2020, driven by higher parts sales and service activity. Gross margin of $5.2 million compared to $5.6 million in the third quarter of 2021 and was up from $3.8 million in the fourth quarter of 2020. Gross margin percentage was 15%, flat compared to the third quarter of 2021 and up from 13% in the prior year quarter.

Balance Sheet

Long-term debt was $1.5 billion at December 31, 2021, reflecting net debt repayment of $158.5 million for the full year 2021. Our leverage ratio was 4.3x, compared to 4.2x as of December 31, 2020. Our available liquidity totaled $502.5 million as of December 31, 2021.

Quarterly Dividend

The dividend was paid on February 15, 2022 to stockholders of record at the close of business on February 8, 2022.

2022 Annual Guidance

Archrock is providing annual guidance as listed below. All figures are in thousands, except percentages and ratios:

        
  Full Year 2022 Guidance 
   Low  High 
Net income (1)  $15,000 $55,000 
Adjusted EBITDA (2)  320,000  360,000 
Cash available for dividend (3)(4)  163,000  181,000 
        
Segment       
Contract operations revenue $660,000 $690,000 
Contract operations gross margin percentage  60% 62%
Aftermarket services revenue $140,000 $155,000 
Aftermarket services gross margin percentage  16% 18%
        
Selling, general and administrative $113,000 $115,000 
        
Capital expenditures       
Growth capital expenditures $150,000 $150,000 
Maintenance capital expenditures  55,000  75,000 
Other capital expenditures  8,000  10,000 



(1) 2022 annual guidance for net income does not include the impact of long-lived and other asset impairment because due to its nature, it cannot be accurately forecasted. Long-lived and other asset impairment does not impact Adjusted EBITDA or cash available for dividend, however it is a reconciling item between these measures and net income. Long-lived and other asset impairment for the years 2021 and 2020 was $21.4 million and $79.6 million, respectively.
(2) Management believes Adjusted EBITDA provides useful information to investors because this non-GAAP measure, when viewed with our GAAP results and accompanying reconciliations, provides a more complete understanding of our performance than GAAP results alone. Management uses this non-GAAP measure as a supplemental measure to review current period operating performance, comparability measure and performance measure for period-to-period comparisons.
(3) Management uses cash available for dividend as a supplemental performance measure to compute the coverage ratio of estimated cash flows to planned dividends.
(4) A forward-looking estimate of cash provided by operating activities is not provided because certain items necessary to estimate cash provided by operating activities, including changes in assets and liabilities, are not estimable at this time. Changes in assets and liabilities were $(9.5) million and $19.1 million for the years 2021 and 2020, respectively.

Management uses these non-GAAP measures as supplemental measures to review current period operating performance, comparability measures and performance measures for period-to-period comparisons.

(1) 2022 annual guidance for net income does not include the impact of long-lived and other asset impairment because due to its nature, it cannot be accurately forecasted. Long-lived and other asset impairment does not impact Adjusted EBITDA or cash available for dividend, however it is a reconciling item between these measures and net income. Long-lived and other asset impairment for the years 2021 and 2020 was $21.4 million and $79.6 million, respectively.
(2) Management believes Adjusted EBITDA provides useful information to investors because this non-GAAP measure, when viewed with our GAAP results and accompanying reconciliations, provides a more complete understanding of our performance than GAAP results alone. Management uses this non-GAAP measure as a supplemental measure to review current period operating performance, comparability measure and performance measure for period-to-period comparisons.
(3)  Management uses cash available for dividend as a supplemental performance measure to compute the coverage ratio of estimated cash flows to planned dividends.
(4)  A forward-looking estimate of cash provided by operating activities is not provided because certain items necessary to estimate cash provided by operating activities, including changes in assets and liabilities, are not estimable at this time. Changes in assets and liabilities were $(9.5) million and $19.1 million for the years 2021 and 2020, respectively.
