Scott Bender, President and CEO of Cactus, commented, “Our industry-leading technology and continued ability to execute placed Cactus in an excellent position to capitalize on the cyclical market recovery that is now underway. As such, Cactus achieved record Product market share(1) during the fourth quarter, as we supplied wellhead equipment for approximately 43% of the U.S. land rigs in operation. Full year and fourth quarter 2020 results highlighted our ability to generate substantial free cash flow and maintain strong margins even in challenging markets.

“Looking to the first quarter of 2021, we expect further gains in rigs followed will benefit our Product business. Additionally, we have witnessed meaningful sequential growth in Rental activity to start the year as customers return to higher-end suppliers with a focus on safety and technology. We expect double digit revenue growth on a percentage basis across all our business lines sequentially during the first quarter, even when accounting for the impact of the adverse weather witnessed in recent weeks.

“In addition to the increased activity witnessed during the fourth quarter, there are a number of positive developments unfolding for Cactus. The macroeconomic environment and associated demand for our products and services is clearly improving in the U.S., as noted by our early 2021 outlook. On the R&D front, we are currently in the late stages of developing technologies specifically designed to reduce the environmental impact of flow control equipment and assist our customers in realizing their ESG-related goals. Additionally, we made our first shipments of equipment to the Middle East in January 2021, which should provide opportunities for growth in the region this year.”

Mr. Bender concluded, “Our performance and recent developments provide grounds for optimism about the trajectory of the business. As always, we will operate with a focus on margins, returns, and creating value for our shareholders.”

Product revenue $ 43,020 $ 35,857 $ 83,371
Gross profit $ 13,268 $ 15,978 $ 31,059
Gross margin 30.8 % 44.6 % 37.3 %

Fourth quarter 2020 product revenue increased $7.2 million, or 20.0%, sequentially, as sales of wellhead and production related equipment increased primarily due to higher drilling activity and increased market share in the U.S. Gross profit decreased $2.7 million, or 17.0%, sequentially, with margins decreasing 1,380 basis points driven largely by a $5.2 million decrease in credits related to tariff refunds. Absent these credits, gross margins would have increased approximately 100 basis points sequentially.

Rental

Gross margin (9.6) % 2.4 % 45.4 %

Fourth quarter 2020 rental revenue decreased $1.3 million, or 13.1%, sequentially, as our customers’ utilization of our rental equipment declined during the quarter. Gross profit decreased $1.1 million sequentially and margins decreased 1,200 basis points due largely to a $0.6 million decrease in credits related to tariff refunds and depreciation expense representing a higher percentage of revenue during the period.

Field Service and Other

Three Months Ended

Gross profit $ 4,957 $ 4,728 $ 4,594
Gross margin 30.1 % 33.6 % 16.0 %

Fourth quarter 2020 field service and other revenue increased $2.4 million, or 17.3%, sequentially, as higher customer activity drove an increase in associated billable hours and ancillary services. Gross profit increased $0.2 million, or 4.8%, sequentially, with margins decreasing by 350 basis points sequentially due to reduced labor utilization associated with the holidays and a reduction in savings related to the optimization of the Company’s vehicle fleet.

Selling, General and Administrative Expenses (“SG&A”)

SG&A for the fourth quarter of 2020 was $9.0 million (13.2% of revenues), compared to $8.4 million (14.0% of revenues) for the third quarter of 2020 and $12.4 million (8.8% of revenues) for the fourth quarter of 2019. The sequential increase was primarily due to higher payroll and safety and training related expenses due to an increase in headcount.

Liquidity, Capital Expenditures and Other

As of December 31, 2020, the Company had $288.7 million of cash and no bank debt outstanding. Operating cash flow was $21.9 million for the fourth quarter of 2020. During the fourth quarter, the Company made dividend payments and associated distributions of $5.0 million.

Net cash used in investing activities represented $1.7 million during the fourth quarter of 2020. Net capital expenditures for the full year 2020 were $18.1 million. For the full year 2021, the Company expects net capital expenditures to be in the range of $10 to $15 million.

Quarterly Dividend

A corresponding distribution of up to $0.09 per CW Unit has also been approved for holders of CW Units of Cactus Wellhead, LLC.

(unaudited)

Net income, as adjusted and diluted earnings per share, as adjusted are not measures of net income as determined by GAAP. Net income, as adjusted and diluted earnings per share, as adjusted are supplemental non-GAAP financial measures that are used by management and external users of the Company’s consolidated financial statements. Cactus defines net income, as adjusted as net income assuming Cactus, Inc. held all units in Cactus LLC, its operating subsidiary, at the beginning of the period, with the resulting additional income tax expense related to the incremental income attributable to Cactus, Inc. Net income, as adjusted, also includes certain other adjustments described below. Cactus defines diluted earnings per share, as adjusted as net income, as adjusted divided by weighted average shares outstanding, as adjusted. The Company believes this supplemental information is useful for evaluating performance period over period.

Cactus, Inc. – Supplemental Information

Reconciliation of GAAP to non-GAAP Financial Measures

EBITDA and Adjusted EBITDA

(unaudited)

EBITDA and Adjusted EBITDA are not measures of net income as determined by GAAP. EBITDA and Adjusted EBITDA are supplemental non-GAAP financial measures that are used by management and external users of the Company’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. Cactus defines EBITDA as net income excluding net interest, income tax and depreciation and amortization. Cactus defines Adjusted EBITDA as EBITDA excluding the other items outlined below.

Cactus management believes EBITDA and Adjusted EBITDA are useful because they allow management to more effectively evaluate the Company’s operating performance and compare the results of its operations from period to period without regard to financing methods or capital structure, or other items that impact comparability of financial results from period to period. EBITDA and Adjusted EBITDA should not be considered as alternatives to, or more meaningful than, net income or any other measure as determined in accordance with GAAP. The Company’s computations of EBITDA and Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. Cactus presents EBITDA and Adjusted EBITDA because it believes they provide useful information regarding the factors and trends affecting the Company’s business.

Cactus, Inc. – Supplemental Information

Estimated Market Share

(unaudited)

Market share represents the average number of active U.S. onshore rigs Cactus followed (which Cactus defines as the number of active U.S. onshore drilling rigs to which it was the primary provider of wellhead products and corresponding services during drilling) as of mid-month for each of the three months in the applicable quarter divided by the Baker Hughes U.S. onshore rig count quarterly average. Cactus believes that comparing the total number of active U.S. onshore rigs to which it was providing its products and services at a given time to the number of active U.S. onshore rigs during the same period provides Cactus with a reasonable approximation of its market share with respect to wellhead products sold and the corresponding services it provides.
