Positives

• Expiration of the Hart-Scott-Rodino waiting period on September 26, 2025, satisfies an important condition for the transaction's completion.
• The setting of an election deadline and expected closing date indicates the merger process is progressing as planned.

Risks

• Challenges in successfully integrating the businesses of WES and Aris.
• Risk of an event, change, or circumstance leading to the termination of the Merger Agreement.
• Possibility that Aris stockholders may not approve the Merger Agreement.
• Inability of the parties to satisfy the conditions to the transaction in a timely manner or at all.
• Disruption of management time from ongoing business operations due to the transaction.
• Adverse effects on the market price of WES Common Units or Aris's Class A common stock due to transaction announcements.
• Adverse effect on the ability of WES and Aris to retain customers, key personnel, and maintain relationships with suppliers and customers.
• Substantial costs incurred by both entities due to the pending transaction.

• Inability to achieve expected synergies or taking longer than expected to achieve them.

Future Outlook

The transaction is expected to close on October 15, 2025, contingent upon Aris stockholder approval and the satisfaction of other customary closing conditions. The combined company anticipates achieving synergies, though there are risks associated with integration and the realization of these benefits.

Industry Context

This merger represents a consolidation within the midstream and water solutions sectors, particularly focused on the Permian Basin. WES, a diversified midstream operator, is expanding its environmental infrastructure capabilities by acquiring Aris, a specialist in water handling and recycling. This aligns with a broader industry trend towards integrating sustainability solutions and optimizing operational efficiencies in energy production, especially in key shale plays like the Permian.

Stakeholder Impact

• Shareholders (Aris): Will receive merger consideration in cash, WES common units, or a combination, based on their election.
• Shareholders (WES): Will see dilution from new units issued and potential benefits from the acquisition of Aris's assets and operations.
• Customers (WES & Aris): Potential for expanded services and integrated solutions from the combined entity.
• Employees (WES & Aris): Integration risks and potential changes in roles or structure post-merger.

Next Steps

• Aris securityholders to deliver properly completed Election Forms by October 7, 2025.
• Aris securityholders to vote on the merger proposal at a special meeting on October 14, 2025.
• Completion of the transaction, expected on October 15, 2025, subject to Aris stockholder approval and other customary closing conditions.

Key Dates

Recommendation

The filing provides an update on the procedural aspects of an ongoing merger, confirming that key conditions have been met and deadlines are approaching. While the HSR clearance is a positive step, the transaction's completion is still subject to Aris stockholder approval and other conditions. The market has likely already priced in the merger announcement from August 6, 2025. Investors holding Aris shares should consider their election options carefully based on their individual investment strategy and tax situation. For WES shareholders, the impact is largely as expected from the initial merger announcement. Therefore, a "hold" recommendation is appropriate as the primary news (the merger itself) has already been disseminated, and this filing is a procedural update.
