Credit Agreement

On August 21, 2018, Cactus LLC entered into a five-year senior secured asset-based revolving credit facility with a syndicate of lenders and JPMorgan Chase Bank, N.A., as administrative agent for such lenders and as an issuing bank and swingline lender (the “ABL Credit Facility”). The ABL Credit Facility provides for $75.0 million in revolving commitments, up to $15.0 million of which is available for the issuance of letters of credit. Subject to certain terms and conditions set forth in the ABL Credit Facility, Cactus LLC may request additional revolving commitments in an amount not to exceed $50.0 million, for a total of up to $125.0 million in revolving commitments.

The ABL Credit Facility matures on August 21, 2023. The maximum amount that Cactus LLC may borrow under the ABL Credit Facility is subject to a borrowing base, which is based on a percentage of eligible accounts receivable and eligible inventory, subject to reserves and other adjustments.

The ABL Credit Facility replaced Cactus LLC’s prior credit agreement, dated as of July 31, 2014, with Credit Suisse AG, as administrative agent, collateral agent and issuing bank, and the other lenders party thereto (the “Prior Credit Agreement”). The Prior Credit Agreement provided for a term loan tranche in an aggregate principal amount of $275.0 million, the outstanding balance of which was repaid in full in February 2018 with the net proceeds of our IPO, and a revolving credit facility (the “Prior Revolving Credit Facility”) of up to $50.0 million with a $10.0 million sublimit for letters of credit. The Prior Credit Agreement was terminated concurrently with the effectiveness of, and as a condition of entering into, the ABL Credit Facility. No loans or letters of credit under the Prior Credit Agreement were outstanding at the time of, or were repaid in connection with, such termination. The Prior Credit Agreement was scheduled to mature on July 31, 2019.

Cactus LLC’s obligations under the ABL Credit Facility are secured by liens on Cactus LLC’s assets, other than equipment, intellectual property and real estate. Any subsidiary of Cactus LLC that is considered material pursuant to the ABL Credit Facility will be required to (i) guarantee on an unconditional basis all of Cactus LLC’s obligations under the ABL Credit Facility and (ii) grant a lien to secure such guarantee on its assets, other than equipment, intellectual property and real estate.

Borrowings under the ABL Credit Facility bear interest at Cactus LLC’s option at either (i) the Alternate Base Rate (as defined therein) (“ABR”), or (ii) the Adjusted LIBO Rate (as defined therein) (“Eurodollar”), plus, in each case, an applicable margin. Letters of credit issued under the ABL Credit Facility accrue fees at a rate equal to the applicable margin for Eurodollar borrowings. The applicable margin ranges from 0.50% to 1.00% per annum for ABR borrowings and 1.50% to 2.00% per annum for Eurodollar borrowings and, in each case, is based on the average quarterly availability under the ABL Credit Facility for the immediately preceding fiscal quarter. The unused portion of the ABL Credit Facility is subject to a commitment fee that varies from 0.250% to 0.375% per annum, according to the average quarterly availability under the ABL Credit Facility for the immediately preceding fiscal quarter.

The ABL Credit Facility contains various covenants and restrictive provisions that limit Cactus LLC’s and each of its subsidiaries’ ability to, among other things:

incur additional indebtedness and create liens;

make investments or loans;

enter into asset sales;

make certain restricted payments and distributions; and

engage in transactions with affiliates.

The ABL Credit Facility also requires Cactus LLC to maintain a fixed charge coverage ratio of 1.0 to 1.0 based on the ratio of EBITDA (as defined therein) minus Unfinanced Capital Expenditures (as defined therein) to Fixed Charges (as defined therein) during certain periods, including when availability under the ABL Credit Facility is under certain levels. If Cactus LLC fails to perform its obligations under the ABL Credit Facility, (i) the commitments under the ABL Credit Facility could be terminated, (ii) any outstanding borrowings under the ABL Credit Facility may be declared immediately due and payable and (iii) the lenders may commence foreclosure or other actions against the collateral.

As of September 30, 2018, we had no borrowings outstanding under the ABL Credit Facility. As of December 31, 2017, we had $248.5 million of borrowings outstanding under the term loan tranche of the Prior Credit Agreement, no borrowings outstanding under the Prior Revolving Credit Facility and no outstanding letters of credit.

At September 30, 2018, although there were no borrowings outstanding, the applicable margin on our Eurodollar borrowings was 1.5% plus an adjusted base rate of one or three month LIBOR. At December 31, 2017, the weighted average interest rate for the borrowings under the Prior Credit Agreement was 7.3%.

As of September 30, 2018, we were in compliance with all covenants under the ABL Credit Facility and as of December 31, 2017, we were in compliance with all covenants under the Prior Credit Agreement.

Loss on Debt Extinguishment

During the first quarter of 2018, we recorded a $4.3 million loss on early extinguishment of debt in conjunction with the repayment of the term loan portion of the Prior Credit Agreement with a portion of the net proceeds from our IPO. The loss consists of the write-off of the unamortized balance of debt discount and deferred loan costs of $2.1 million and $2.2 million, respectively. The loss on debt extinguishment is included under other income (expense), net, in the consolidated statements of income.
