Oil States Amends and Extends its Senior Secured Revolving Credit Facility

HOUSTON, Jan. 30, 2018 -- Oil States International, Inc. (NYSE:OIS) announced today that it has amended its credit agreement (the amended credit agreement) contemporaneously with the closing of its private offering of $200 million principal amount of 1.50% convertible senior notes due 2023. Total lender commitments under the amended revolving credit facility are $350 million. The amended revolving credit facility can be increased up to an incremental $150 million, subject to additional lender commitments. The maturity date of the amended credit agreement has been extended to January 30, 2022.

The amended credit agreement contains customary financial covenants and restrictions. Specifically, the Company must maintain an interest coverage ratio (defined as the ratio of consolidated EBITDA (as defined in the amended credit agreement)) to consolidated interest expense of at least 3.00x to 1.00x. In addition, the Company must maintain a maximum senior leverage ratio (defined as the ratio of senior debt to consolidated EBITDA) of no greater than 2.25x to 1.00x, and a total net leverage ratio (defined as the ratio of total net funded debt to consolidated EBITDA) of no greater than 4.00x to 1.00x through the quarter ending December 31, 2018, and no greater than 3.75x to 1.00x thereafter.

Borrowings outstanding under the amended revolving credit facility will bear interest at LIBOR plus a margin of 1.75% to 3.00%, or at a base rate plus a margin of 0.75% to 2.00%, in each case based on a ratio of the Company’s total net funded debt to consolidated EBITDA. Oil States must also pay a quarterly commitment fee of 0.25% to 0.50%, based on its ratio of total net funded debt to consolidated EBITDA, on the unused commitments.
