Enphase Energy's stock surged 5.10% in after-hours trading following the release of its fourth-quarter financial results, which exceeded analyst expectations on key metrics.

The company reported adjusted earnings per share of $0.71 for Q4 2025, significantly beating the consensus estimate of $0.58. Revenue came in at $343.3 million, also surpassing the expected $340.6 million. Additionally, Enphase provided first-quarter 2026 revenue guidance in the range of $270 million to $300 million, which is above the analyst estimate of $262.2 million.

Key drivers for the positive results included increased sell-through demand in the U.S. driven by solar and battery installations ahead of tax credit expiration, as well as recent product launches such as the IQ9N-3P microinverter. The company also reported strong free cash flow of $37.8 million and ended the quarter with $1.51 billion in cash and marketable securities.
