Shares of Enphase Energy, Inc. (ENPH) have lost 28.2% in the past three months compared with the 7.1% decline of the Zacks solar industry. It underperformed the Zacks Oil-Energy sector’s growth of 1.8% and the S&P 500’s rise of 9.1%.

Shares of CSIQ have gained 14.1%, while shares of SEDG have gained 37.2%.
With ENPH’s dismal performance on the bourses, some investors may seek this as a potential buying opportunity. However, before making any decision, it is important to understand the factors behind this weak performance. Can the company overcome its challenges and return to growth, or will risks continue to weigh on its future performance? The aim is to help investors make a more informed decision.
What Pushed ENPH Down?
ENPH’s stock has been under pressure due to weak demand and tough market conditions in recent months. In the second quarter of 2025, its international sales fell compared with last year, mainly because of lower demand in Europe. Countries like the Netherlands and France saw fewer installations as lower utility rates and policy changes made solar projects less attractive.
The company’s profits have also been hit by higher production costs, partly caused by new U.S. tariffs on imports from key suppliers. Further, U.S. policy changes under the One Big Beautiful Bill Act have added to concerns for ENPH. The act reduced tax credits for residential solar and storage projects and set stricter timelines, making it harder for some projects to move forward. These policy changes, coupled with a slow demand environment, might have raised doubts about ENPH’s near-term growth, leading to its investors losing confidence in this stock, which resulted in its dismal share price performance.
What Lies Ahead for ENPH Stock?
Enphase Energy, being a prominent solar microinverter manufacturer, is expanding globally with shipments of its IQ8P to Japan, Vietnam, Malaysia, Colombia, Panama, and Costa Rica. The upcoming launch of its next-gen IQ9 microinverter is expected to further strengthen its product portfolio. Additionally, Enphase Energy is bolstering its battery storage segment with the IQ Battery 5P and FlexPhase in Europe, while developing a fifth-generation battery offering 50% higher energy density and lower costs. These innovations, coupled with geographic expansion, position ENPH to capitalize on growing solar and storage demand, enhancing its competitive edge and driving future revenue growth.
A strong financial position supports these initiatives. As of June 30, 2025, Enphase Energy had cash and cash equivalents, including marketable securities, of $1.53 billion. Its long-term debt was $0.57 billion and current debt totaled $0.63 billion. Since both long-term and current debts are lower than its cash balance, the company maintains a solid solvency position. This financial strength has also allowed Enphase Energy to repurchase shares worth about $130 million in the first half of 2025, with $268.7 million still authorized for buybacks.
ENPH’s Near-Term Estimates
The Zacks Consensus Estimate for ENPH’s 2025 revenues indicates a solid improvement of 8.6% from the prior-year level. The estimate for its earnings also indicates a year-over-year improvement.
