On June 11, 2026, VettaFi announced that WaterBridge Infrastructure LLC (NYSE:WBI, NYSE TX: WBI)) (the "Company" or "WaterBridge") will be added to the indexes listed below following the close of trading on Thursday, June 18, 2026.

Each of the following indexes is a capped, float-adjusted, capitalization-weighted index whose constituents earn the majority of their cash flow from midstream activities involving energy commodities:

Alerian MLP Infrastructure Index (AMZI) — a composite of energy infrastructure companies
Alerian Midstream Energy Index (AMNA) — a broad-based composite of North American energy infrastructure companies
Alerian US Midstream Energy Index (AMUS) — a broad-based composite of U.S. energy infrastructure companies
Alerian MLP Index (AMZ) — the leading gauge of energy infrastructure companies
Alerian Midstream Energy Select Index (AMEI) — a composite of North American energy infrastructure companies engaged in midstream activities
Alerian Midstream Energy Corporation Index (AMCC) – a broad-based composite of North American energy infrastructure corporations

"WaterBridge's inclusion across multiple Alerian indexes is a meaningful milestone that reflects the scale and quality of our water infrastructure platform," said Scott McNeely, Chief Financial Officer of WaterBridge. "These benchmarks are widely tracked by institutional investors in the midstream energy space, and we believe this recognition will broaden our investor base and enhance liquidity in WBI shares over time."

The Alerian Index Series is widely used by industry executives, investment professionals, research analysts, and national media to analyze relative performance. The Alerian MLP ETF (AMLP), which tracks the AMZI, has over $12 billion in assets and is one of the largest energy ETFs in the United States.

WaterBridge also announced today that its board of directors has formed a special committee of independent directors to evaluate a potential conversion from a Delaware limited liability company to a Texas corporation. A primary driver of this evaluation is index eligibility. Major benchmarks — including key S&P, Russell and CRSP indexes — restrict eligibility to corporations, and WaterBridge believes conversion could unlock inclusion in these widely followed indexes. WaterBridge anticipates such inclusion would broaden its eligible investor base, improve trading liquidity, and increase market visibility, each of which would enhance the Company's ability to pursue growth on favorable terms and support long-term shareholder value.

The special committee will evaluate the potential benefits and risks of such a conversion, including the impact on WaterBridge's governance structure and tax treatment. There can be no assurance that the special committee will recommend a conversion or that any such conversion, if recommended, will be completed. In addition, there can be no assurance that WaterBridge, if converted to a corporate entity, will be included in any particular index or that any such index inclusion will generate the expected benefits. WaterBridge expects to provide additional information regarding the special committee's review and any potential conversion at a later date.
