Soluna announced completion of Project Kati 1 (83 MW energized) and conditional Base Load classification from ERCOT for the full 166 MW campus. This represents a material operational milestone—the company delivered on its timeline, increased total operating capacity to 206 MW, and secured favorable grid interconnection status. While not a traditional M&A, earnings release, or governance event, this operational achievement materially advances the company's strategic capacity expansion and grid positioning.

Soluna announced the closing of a 397-acre land purchase in Briscoe County, Texas for "Project Dorothy 3," a planned 300 MW renewable-first AI computing campus. This is a material operational/strategic milestone involving significant capital deployment and real estate acquisition that advances the company's development pipeline (6.3 GW across multiple sites). While not a traditional M&A transaction (acquisition of another company), it represents a material operational event—a major property acquisition and project development milestone—that would affect a reasonable investor's assessment of the company's growth trajectory and capital allocation.
