Organization and Nature of Operations	1. Organization and Nature of Operations WaterBridge Infrastructure LLC (the “Company,” “WaterBridge,” “we,” “our” and “us”) is headquartered in Houston, Texas and was formed on April 11, 2025, as a Delaware limited liability company to serve as the issuer in our initial public offering (the “IPO” and, collectively with our related corporate reorganization and transactions in connection therewith, the “WaterBridge Combination”). We are governed by our First Amended and Restated Limited Liability Company Agreement, dated as of September 18, 2025 (the “LLC Agreement”), which was entered into in connection with the IPO. We are a holding company whose principal asset consists of membership interests (“OpCo Units”) in WBI Operating LLC (“OpCo”). Under the OpCo LLC Agreement, we have been designated as the managing member of OpCo and its subsidiaries, and, as the managing member, we operate and control all of the business and affairs of OpCo and its subsidiaries, and through OpCo and its subsidiaries, conduct our business. The Company did not have any business transactions or activities from its inception until the acquisition of the OpCo Units, other than related to its formation and its initial capitalization. The Company has no other operations, cash flows or material assets or liabilities other than our investment in OpCo, obligations related to our tax receivable agreement (the “TRA”) and certain deferred tax assets and liabilities. Refer to Note 6 — Income Taxes and Tax Receivable Agreement for additional information. We generate revenue primarily by charging produced water handling fees for transporting produced water for disposal to our produced water handling facilities and, to a lesser extent, by providing raw or recycled produced water to customers for reuse in drilling and completion operations and oilfield waste reclamation and disposal operations. By focusing on produced water handling, our revenues are tied primarily to the long-life production of oil and natural gas wells rather than drilling activity, which can be more cyclical in nature. Our assets primarily consist of produced water handling and recycling facilities, water pipeline systems, brackish water wells and ponds, and related facilities within the Delaware Basin in West Texas and New Mexico, the Eagle Ford Basin in South Texas and the Arkoma Basin in Oklahoma. We also operate two environmental waste management facilities for the disposal of non-hazardous waste resulting from oil and gas exploration and production activity in the Delaware Basin and provide gas transportation services in the Arkoma Basin. One of our predecessors for U.S. Securities and Exchange Commission (the “SEC”) reporting purposes is WaterBridge NDB Operating LLC (“NDB Operating”), an indirect, wholly-owned subsidiary of NDB Midstream LLC (“NDB Midstream”). NDB Midstream was the accounting acquirer in the WaterBridge Combination on September 17, 2025, as set forth in Note 1 — Organization and Nature of Operations, included in Part II, Item 8 of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Form 10-K”). Accordingly, the historical financial information of WaterBridge reflects the operations of NDB Operating and its subsidiaries for periods prior to the completion of the WaterBridge Combination on September 17, 2025.
