Avangrid scraps $4.3 billion takeover of PNM Resources

Details: This merger was inked in late 2020 and touted as creating the country's third-largest renewable energy company. But New Mexico utility authorities rejected the deal in 2021, leading to a protracted court battle that Iberdrola opted to end.

• PNM had offered to again extend the closing deadline, and says it's "greatly disappointed" by Iberdrola's decision.
• With assumed debt included, the merger would have been worth more than $8.5 billion.

What to watch: Iberdrola may seek reduce its 81.6% stake in Avangrid, which trades on the New York Stock Exchange with around a $12.5 billion market cap.
