In this article, we are going to discuss the energy stocks that are losing this week.

Last week was a disastrous one for America’s solar energy industry, with some major solar stocks plummeting by as much as 35%. The House of Representatives narrowly passed President Trump’s sweeping tax and spending bill, potentially ending key Biden-era tax credits years sooner than expected. These subsidies have been crucial for the American solar, wind, and energy storage sectors, which rely on them heavily for financial viability.

Though the legislation is expected to raise about $500 billion in revenue over a decade by rolling back the renewable energy credits, it puts America’s energy security at risk. Solar and battery storage is the fastest-growing energy source in the United States, making up 81% of expected power additions to the grid in 2025, according to the Energy Information Administration. Moreover, a slowdown in solar deployment could be especially damaging at a time when the AI boom is expected to raise America’s electricity demand to record levels.

Green energy stakeholders will now be looking towards the Senate and hoping that it will reverse many of the proposed revisions to President Joe Biden’s Inflation Reduction Act, which has played a vital role in jumpstarting America’s green energy transition.

10. First Solar, Inc. (NASDAQ:FSLR)

Share Price Decline Between May 20 – May. 27: 6.87%

First Solar, Inc. (NASDAQ:FSLR) is a leading American solar technology company and global provider of responsibly produced, eco-efficient solar modules.

First Solar, Inc. (NASDAQ:FSLR) suffered a setback last week after House Republicans passed a tax bill that terminates key clean energy credits that have been necessary to sustain the country’s solar energy industry. The ‘one big beautiful bill’ makes it impossible for solar energy players to claim or transfer tax credits, while terminating them completely for installers that lease equipment to customers.

However, as the biggest producer of solar panels in the U.S. with a large domestic manufacturing footprint, First Solar remained relatively unhurt since manufacturing subsidies do not appear to have been touched.

Another development working in favor of First Solar, Inc. (NASDAQ:FSLR) last week is when Jefferies analyst Julian Dumoulin-Smith updated the price target for FSLR from $127 to $157, while maintaining a Hold rating on the stock.

9. NextEra Energy, Inc. (NYSE:NEE)

Share Price Decline Between May 20 – May. 27: 8.56%

NextEra Energy, Inc. (NYSE:NEE) is the world’s largest generator of renewable energy from the wind and sun and a global leader in battery storage.

President Trump’s sweeping tax and spending bill, intended to end Biden-era tax credits for clean energy projects years sooner than planned, poses a threat to NextEra Energy, Inc. (NYSE:NEE)’s operations as it is also the Florida Power & Light Company – America’s largest electric utility which benefits greatly from Florida’s famous sunshine and growing population.

However, on the plus side, NEE has positioned itself well during the ongoing global trade war by shifting its tariff exposure to suppliers and contracting with domestic battery manufacturers.

8. Array Technologies, Inc. (NASDAQ:ARRY)

Share Price Decline Between May 20 – May. 27: 8.74%

Array Technologies, Inc. (NASDAQ:ARRY) is a leading global provider of solar tracking technology to utility-scale and distributed generation customers, who construct, develop, and operate solar PV sites.

The share price of Array Technologies, Inc. (NASDAQ:ARRY) fell last week after investors reacted negatively to the House of Representatives advancing President Trump’s ‘one big beautiful bill’, which may end numerous green-energy subsidies that have supported the renewable energy sector. While the industry was already expecting the gradual phase-out of wind and solar tax credits, the latest version of the bill accelerates this timeline, dealing a serious blow to the solar energy industry, which relies heavily on such credits.

That said, Array Technologies, Inc. (NASDAQ:ARRY) posted strong results for its Q1 2025 earlier this month, beating expectations in both revenue and earnings. The company reported a strong revenue growth of 97.1% YoY and achieved the second-largest quarter of volume shipped since 2023, indicating solid market share recovery.

7. New Fortress Energy Inc. (NASDAQ:NFE)

Share Price Decline Between May 20 – May. 27: 8.82%

New Fortress Energy Inc. (NASDAQ:NFE) owns and operates natural gas and LNG infrastructure and an integrated fleet of ships and logistics assets to rapidly deliver turnkey energy solutions to global markets.

New Fortress Energy Inc. (NASDAQ:NFE) continues to plunge after posting a wide earnings miss in its Q1 2025 earlier this month, struggling with weak performance across all its segments. The company’s loss of $0.73 per share was significantly worse than market expectations, while its revenue also declined by over 31% YoY and fell below estimates. Investors also reacted negatively when it was revealed this week that the company has been disqualified from an auction held by the Puerto Rican government to secure temporary power generation.

However, the latest blow for New Fortress Energy Inc. (NASDAQ:NFE) has come in the form of a notice it received from NASDAQ on non-compliance with the stock market’s listing rule for not submitting its quarterly reports with the U.S. Securities and Exchange Commission.

6. LandBridge Company LLC (NYSE:LB)

Share Price Decline Between May 20 – May. 27: 8.97%

LandBridge Company LLC (NYSE:LB) actively manages its land and resources to support and encourage oil and natural gas development and other critical land uses.

LandBridge Company LLC (NYSE:LB) suffered a blow last week after analysts at Johnson Rice downgraded the firm’s rating from Buy to Accumulate, reflecting a shift in the firm’s recommendation for how investors should approach the stock.

LandBridge Company LLC (NYSE:LB) reported mixed results for its Q1 2025 earlier this month, with its EPS of $0.22 falling below expectations by $0.14. However, the company’s revenue grew by 131% YoY to $43.95 million and missed estimates by over $826,000. LandBridge also declared a quarterly cash dividend of $0.1 per share, in line with previous.

5. Fluence Energy, Inc. (NASDAQ:FLNC) 

Share Price Decline Between May 20 – May. 27: 9.89%

Fluence Energy, Inc. (NASDAQ:FLNC) is a global market leader delivering intelligent energy storage and optimization software for renewables and storage.

Fluence Energy, Inc. (NASDAQ:FLNC) surged by over 35% earlier this month after posting better-than-expected results for its Q2 2025, beating market estimates in both revenue and adjusted EPS. However, the company reduced its guidance for the second quarter in a row, primarily due to the economic uncertainty caused by President Trump’s tariffs. So the recent downturn in share price could be due to investors taking their profits.

Another factor contributing to the decline in Fluence Energy, Inc. (NASDAQ:FLNC) is Jeffries’ recently downgrading the stock from Hold to Underperform, while also reducing its price target from $4 to $3.

4. The AES Corporation (NYSE:AES)

Share Price Decline Between May 20 – May. 27: 10.41%

The AES Corporation (NYSE:AES), together with its subsidiaries, operates as a power generation and utility company in the United States and internationally.

A number of factors have put downward pressure on the share price of The AES Corporation (NYSE:AES) this month. The company reported lower-than-expected results for its Q1 2025, missing estimates in both earnings and revenue. Moreover, AES has suffered a blow from President Trump’s tax bill, with a potential slowdown expected in the renewable business outlook starting in 2027 and beyond. The wind and solar industries, in particular, have suffered a setback, and AES has been investing in these two renewable sectors since 2002.

Lastly, The AES Corporation (NYSE:AES) was recently downgraded by analysts at Jeffries and Argus Research due to concerns about the company’s future, particularly in the renewable sector.

3. SolarEdge Technologies, Inc. (NASDAQ:SEDG)

Share Price Decline Between May 20 – May. 27: 16.61%

SolarEdge Technologies, Inc. (NASDAQ:SEDG) is a global leader in smart energy technology. The company produces current optimized inverter systems for solar photovoltaic installations in the United States, Germany, the Netherlands, Italy, the rest of Europe, and internationally.

SolarEdge Technologies, Inc. (NASDAQ:SEDG) suffered a blow last week after President Trump’s sweeping tax and spending bill passed through the House of Representatives, which may result in the termination of numerous subsidies that have supported the renewable energy sector and have devastating consequences for the rapidly expanding solar power industry.

The rooftop solar industry is expected to suffer in particular, as the bill ends tax credits for installers that lease equipment to customers, in addition to eliminating a tax credit for homeowners who own their own panels. Consequently, SolarEdge Technologies, Inc. (NASDAQ:SEDG) crashed as its inverter sales are expected to take a hit from lower demand for rooftop solar.

2. Enphase Energy, Inc. (NASDAQ:ENPH) 

Share Price Decline Between May 20 – May. 27: 17.99%

Enphase Energy, Inc. (NASDAQ:ENPH) is a global energy technology company and the world’s leading supplier of micro-inverter-based solar and battery systems. The company has shipped approximately 80 million microinverters, and approximately 4.7 million Enphase-based systems have been deployed in more than 160 countries around the world.

Enphase Energy, Inc. (NASDAQ:ENPH) plunged after investors reacted negatively to the House of Representatives narrowly passing President Trump’s ‘one big beautiful bill’, which ends the investment and electricity production credits for clean energy facilities. Those credits have played a key role in the rapid expansion of utility-scale solar projects in the country. The rooftop solar industry faces a fatal blow as the bill would remove the 30% federal tax credit for taxpayers who install solar rooftop systems, potentially causing a drop in sales of ENPH’s inverters.

Enphase Energy, Inc. (NASDAQ:ENPH) also faced downward pressure after the stock was downgraded by BMO Capital from Market Perform to Underperform, with its price target also reduced from $46 to $39.

1. Sunrun Inc. (NASDAQ:RUN) 

Share Price Decline Between May 20 – May. 27: 37.69%

Sunrun Inc. (NASDAQ:RUN) is America’s leading provider of clean energy as a subscription service, offering residential solar and energy storage with no upfront costs.

The share price of Sunrun Inc. (NASDAQ:RUN) nosedived last week after the House of Representatives narrowly passed President Trump’s sweeping tax and spending bill, potentially ending Biden-era tax credits for clean energy projects years sooner than planned. The bill could deal a massive blow to the country’s solar energy industry, which depends heavily on these credits to sustain itself.

The already struggling rooftop solar industry has been hit particularly hard as the credits for rooftop solar and battery storage would end this year, if the bill also manages to pass through the Senate. Since around 70% of the rooftop solar industry now uses lease arrangements, the legislation could prove disastrous for companies like Sunrun Inc. (NASDAQ:RUN) that lease equipment to customers. Moreover, the bill eliminates the ‘transferability’ of tax credits for installers, which puts the whole business model of Sunrun under threat since the company generated over $700 million last year from transferring investment tax credits from its solar and storage projects.
