Contingencies	Contingencies ARO Newbuild Funding Obligations In connection with our 50/50 unconsolidated joint venture, we have a potential obligation to fund ARO for newbuild jackup rigs. The Shareholder Agreement specifies that ARO shall purchase 20 newbuild jackup rigs over an approximate 10-year period. The joint venture partners intend for the newbuild jackup rigs to be financed out of available cash on hand and from ARO's operations and/or funds available from third-party financing. The first two newbuild jackups, Kingdom 1 and Kingdom 2, were delivered and commenced operations in 2023 and 2024, respectively. In October 2024, ARO ordered the third newbuild jackup, Kingdom 3, for a purchase price of approximately $300.0 million, and paid the 25% down payment from cash on hand. The final payment will be due upon delivery of the rig. In the event ARO has insufficient cash or is unable to obtain third-party financing, each partner may periodically be required to make additional capital contributions to ARO, up to a maximum aggregate contribution of $1.25 billion from each partner to fund the newbuild program. Beginning with the delivery of the second newbuild, each partner's commitment is reduced by the lesser of the actual cost of each newbuild rig or $250.0 million, on a proportionate basis. Following the delivery of Kingdom 2, our commitment to fund the newbuild program has been reduced to $1.1 billion. Letters of Credit In the ordinary course of business with customers and others, we have entered into letters of credit to guarantee our performance as it relates to our drilling contracts, contract bidding, customs duties, tax appeals and other obligations in various jurisdictions. Letters of credit outstanding as of June 30, 2025 totaled $30.0 million and are issued under facilities provided by various banks and other financial institutions, but none were issued under the 2028 Credit Agreement. Obligations under these letters of credit are not normally called, as we typically comply with the underlying performance requirements. As of June 30, 2025, we had collateral deposits in the amount of $11.2 million with respect to these agreements. Patent Litigation In December 2022, a subsidiary of Transocean Ltd. commenced an arbitration proceeding against us alleging breach of a license agreement related to certain dual-activity drilling patents. In July 2025, the arbitration tribunal rendered a final decision awarding Transocean Ltd. $7.9 million in damages, including interest, and awarded Valaris $7.4 million as reimbursement for legal fees incurred in connection with this matter. As a result of this decision, in the three months ended June 30, 2025, we reversed $17.1 million of the $25.0 million liability previously accrued in 2024, leaving a balance of $7.9 million within Accrued liabilities and other on our Consolidated Balance Sheet as of June 30, 2025. Additionally, we recognized a $7.4 million receivable for the recovery of legal fees incurred within Accounts receivable, net on the Consolidated Balance Sheet as of June 30, 2025. Brazil Administrative Matter In July 2023, we received notice of an administrative proceeding initiated against us in Brazil. Specifically, the Federal Court of Accounts (“TCU”) sought from us, Samsung Heavy Industries (“SHI”) and others, on a joint and several basis, a total of approximately BRL 601.0 million (approximately $110.0 million at the current period‑end exchange rate) in damages that TCU asserted arose from the overbilling to Petrobras in 2015 in relation to the drilling services agreement with Petrobras for VALARIS DS-5 (the “DSA”). As fully disclosed in our prior periodic reports, the DSA was previously the subject of (1) investigations by the SEC and the U.S. Department of Justice, each of which closed their investigation of us in 2018 without any enforcement action, (2) an arbitration proceeding against SHI in which we prevailed, resulting in SHI making a $200.0 million cash payment to us in December 2019, and (3) a settlement with Petrobras normalizing our business relations in August 2018. In May 2024, the Brazilian prosecutor issued an opinion recommending that the TCU close this matter against us. In July 2025, a trial was held and all claims against us were dismissed. Other Matters In addition to the foregoing, we are named defendants or parties in certain other lawsuits, claims or proceedings incidental to our business and are involved from time to time as parties to governmental investigations or proceedings, including matters related to taxation, arising in the ordinary course of business. Although the outcome of such lawsuits or other proceedings cannot be predicted with certainty and the amount of any liability that could arise with respect to such lawsuits or other proceedings cannot be predicted accurately, we do not expect these matters to have a material adverse effect on our financial position, operating results and cash flows.
