In a recent SEC filing, SIR Capital Management disclosed a significant increase in its investment in Enphase Energy. These quarterly filings are released with a delay, and this one, dated August 14, 2026, reflects trading activity that occurred during the second quarter ending June 30. SIR Capital boosted its holdings by over 180%, from 78,700 shares to approximately 220,500, raising the position's reported value to $10.86 million.
This increased investment took place during a quarter where Enphase saw mixed results. The company reported that its revenue had declined nearly 20% year-over-year, citing continued pressure from higher interest rates and weaker sales in the United States. However, Enphase also managed to improve its gross margin and maintain positive cash flow from operations during the same period.
