  • high

    Oceaneering is in advanced discussions to amend its revolving credit facility, increasing commitments from $215M to up to $345M, extending maturity from 2027 to 2031, and reducing borrowing costs, though the amendment is contingent on completing the notes offering and commencing the tender.

    Exhibit 99.2 view on EDGAR →

Summary

Oceaneering disclosed a comprehensive debt refinancing package on June 24, 2026. The company is issuing $500 million in new senior notes due 2034 through a private placement and simultaneously tendering for all $500 million of its existing 6.00% notes due 2028.

This transaction extends the company's debt maturity profile by six years, from 2028 to 2034, and likely reduces interest expense given current market conditions. The tender offer is conditioned on completing the debt financing, with expiration set for June 30, 2026 and settlement expected July 6, 2026.

In parallel, Oceaneering is negotiating to expand and extend its revolving credit facility, increasing commitments by up to $130 million (from $215M to up to $345M) and pushing the maturity from 2027 to 2031. The credit amendment would also reduce borrowing costs through lower applicable margins. While in advanced discussions, this amendment is not yet finalized and is contingent on completing the notes offering and commencing the tender. The refinancing package represents proactive liability management, extending maturities and potentially improving liquidity, though execution risk remains until all components close.

Added Private offering of $500M senior notes due 2034 high

Added in current filing · verify on EDGAR →

Oceaneering International, Inc. (“Oceaneering”) (NYSE:OII) announced today that it intends to offer $500,000,000 aggregate principal amount of Senior Notes due 2034 (the “2034 Notes”) in a private placement to eligible purchasers.

Oceaneering is launching a private placement of $500 million in senior notes maturing in 2034. The notes will be offered to qualified institutional buyers under Rule 144A and to non-U.S. persons under Regulation S, meaning this is an unregistered offering to sophisticated investors only.

Added Use of proceeds for tender offer and debt management high

Added in current filing · view on EDGAR →

Oceaneering intends to use the net proceeds from the proposed offering, together with cash on hand, if necessary, to fund the purchase of any and all of its 6.000% Senior Notes due 2028 (the “Tender Notes”) validly tendered and accepted for purchase in the concurrent cash tender offer announced today (the “Tender Offer”). If the Tender Offer is not consummated or the net proceeds from the offering exceed the total consideration payable in the Tender Offer, Oceaneering intends to use the remaining net proceeds from the offering for general corporate purposes, which may include the repayment, redemption, or repurchase of outstanding indebtedness.

The company plans to use proceeds from the new 2034 notes to buy back its existing 6.000% senior notes due 2028 through a concurrent tender offer. This is a debt refinancing transaction that extends maturity from 2028 to 2034. Any excess proceeds will go toward general corporate purposes including potential additional debt reduction.

Added Contingencies and execution risk medium

Added in current filing · view on EDGAR →

We expect that the effectiveness of the Credit Agreement Amendment would be subject to the satisfaction of certain customary conditions, including the completion of the offering of notes and the commencement of the tender offer. However, there can be no assurance that the Credit Agreement Amendment will be executed on our expected timeline or at all, or on the terms that we expect (including whether we will receive commitments up to $345,000,000), and the offering is not conditioned upon the execution of such an amendment to our Credit Agreement.

The credit facility amendment is contingent on completing a notes offering and commencing a tender offer, with no guarantee the amendment will close on the expected timeline, terms, or full $345 million commitment amount. The notes offering itself is not dependent on the credit amendment closing.

Event · Exhibit 99.3

2 Added
Added Tender offer conditioned on debt financing high

Added in current filing · view on EDGAR →

The tender offer is conditioned upon the satisfaction or waiver of certain conditions, including Oceaneering’s completion of one or more debt financing transactions on terms satisfactory to it. The tender offer is not conditioned upon any minimum amount of Notes being tendered.

The tender offer is contingent on Oceaneering completing one or more debt financing transactions on satisfactory terms, indicating the company intends to refinance rather than retire this debt. There is no minimum tender condition, meaning Oceaneering will accept any amount tendered if the financing condition is met. This suggests a refinancing strategy, likely to reduce interest costs or extend maturities.

Added Tender offer mechanics and timeline medium

Added in current filing · view on EDGAR →

The tender offer will expire at 5:00 p.m., New York City time, on June 30, 2026, unless extended or earlier terminated (the “Expiration Time”). ... Oceaneering expects to pay the consideration for Notes validly tendered and not validly withdrawn at or prior to the Expiration Time and accepted for purchase by it or tendered and delivered through the guaranteed delivery procedures on July 6, 2026, the third business

day following the Expiration Time (the “Settlement Date”).

The tender offer expires June 30, 2026, with settlement scheduled for July 6, 2026. Noteholders can withdraw tendered notes at any time prior to expiration or, if the offer is extended, within ten business days of commencement. The purchase price will be determined based on Treasury yields as of 2:00 p.m. on June 30, 2026, plus accrued interest through the settlement date.
