Key Dates

Recommendation

This filing provides a procedural update on the pending merger between Western Midstream and Aris Water Solutions, confirming the expiration of a key regulatory waiting period and setting the election deadline for merger consideration. It does not introduce new financial performance data or strategic shifts beyond the merger itself. For Aris shareholders, the primary action is to elect their preferred form of consideration, a mechanical step in a known event. For WES shareholders, the merger is proceeding as anticipated. Given that the core investment thesis for both companies is already tied to the successful completion and integration of this merger, which is progressing as expected, a 'hold' recommendation is appropriate. Investors should have already factored in the merger announcement and its terms.
