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

Though the overall market hit its all-time high recently this week, the broader energy sector still managed to outperform it on a weekly basis, with gains of 2.34% between September 18 and September 25.

However, Wood Mackenzie issued a warning to the global oil and gas industry in their latest report, stating that the sector needs to brace for a tough year in 2026, with capital budgets set to decline as firms prioritize financial strength over long-term growth investments.

Tom Ellacott, Senior Vice President of Corporate Research at Wood Mackenzie, stated:

“Oil and gas companies are caught between competing pressures as they plan for 2026. Near-term price downside risks clash with the need to extend hydrocarbon portfolios into the next decade. Meanwhile, shareholder return of capital and balance sheet discipline will constrain reinvestment rates.”

10. Frontline plc (NYSE:FRO)

Share Price Decline Between Sep 18 – Sep 25: 3.23%

Frontline plc (NYSE:FRO) is a shipping company that engages in the ownership and operation of oil and product tankers worldwide.

Frontline plc (NYSE:FRO), together with other international operators, recently expressed ‘grave’ concerns about the Net Zero Framework proposed for adoption next month at the UN International Maritime Organization environmental committee that seeks to cut marine fuel emissions. The proposed regulation seeks to cut marine fuel emissions, since the global shipping industry accounts for nearly 3% of the world’s carbon emissions.

The Trump administration has already opposed the deal, with threats of tariffs, visa restrictions, and port levies on countries that support it.

Despite the recent downturn, the share price of Frontline plc (NYSE:FRO) has surged by over 57% since the beginning of the year.

9. Teekay Tankers Ltd. (NYSE:TNK)

Share Price Decline Between Sep 18 – Sep 25: 3.91%

Teekay Tankers Ltd. (NYSE:TNK) provides marine transportation services to the oil industry in Bermuda and internationally.

Teekay Tankers Ltd. (NYSE:TNK) was among the shipping stocks that took a hit this week after a consortium of global shipping operators expressed ‘grave’ concerns about the Net Zero Framework tabled for adoption next month at the United Nations’ International Maritime Organization.

The companies made the following statement regarding the deal, which seeks to speed up decarbonization through a bigger regulatory framework:

“We do not believe the IMO NZF will serve effectively in support of decarbonizing the maritime industry… nor ensure a level-playing field as intended. We believe that critical amendments to the IMO NZF are needed, including the consideration of realistic trajectories… before adoption can be considered.”

The United States has already rejected the deal and has threatened tariffs, visa restrictions, and port levies on countries that support it.

8. Greenfire Resources Ltd. (NYSE:GFR)

Share Price Decline Between Sep 18 – Sep 25: 6.02%

Greenfire Resources Ltd. (NYSE:GFR) is an oil sands producer that is actively developing its long-life and low-decline thermal oil assets in the Athabasca region of Alberta, Canada.

Greenfire Resources Ltd. (NYSE:GFR) took a hit after BMO Capital analyst Tariq Saad downgraded the stock from ‘Outperform’ to ‘Market Perform’, with a price target of C$8. The analyst expects the company to ‘materially outspend’ its cash flow next year, which would drive the company’s leverage higher, especially in a low-price environment.

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

Share Price Decline Between Sep 18 – Sep 25: 7.79%

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) shot up by over 110% earlier this month after the company announced that it had scored a $4 billion contract to supply LNG to Puerto Rico. The 7-year agreement, with the option to extend for an additional three years, provides a much-needed boost to New Fortress, which has been struggling with mounting debt, delayed projects, and profitability challenges.

So the recent fall in share price could be due to investors taking their profits. It must also be noted that New Fortress Energy Inc. (NASDAQ:NFE) plunged to an all-time low recently after posting a dramatic decline in revenue and profitability for its second quarter of 2025.

6. Transocean Ltd. (NYSE:RIG)

Share Price Decline Between Sep 18 – Sep 25: 8.67%

Next on our list of Energy Stocks that Lost This Week is Transocean Ltd. (NYSE:RIG), a leading international provider of offshore contract drilling services for oil and gas wells.

Transocean Ltd. (NYSE:RIG) fell after the company announced that it intends to offer and sell 125 million shares in an underwritten public offering, par value $0.10, at a public offering price of $3.05 per share. The gross proceeds from the offering, before deducting underwriting discounts and commissions and expenses, are expected to be around $381.25 million.

Moreover, the offshore drilling contractor granted the underwriters a 30-day option to purchase up to an additional 18.75 million shares in the offering at the public offering price, less underwriting discounts and commissions. Transocean Ltd. (NYSE:RIG) intends to use the net proceeds for the repayment or redemption of indebtedness and general corporate purposes.

5. NGL Energy Partners LP (NYSE:NGL)

Share Price Decline Between Sep 18 – Sep 25: 8.91%

NGL Energy Partners LP (NYSE:NGL) is a diversified midstream MLP that provides multiple services to producers and end-users, including transportation, storage, blending, and marketing of crude oil, NGLs, refined products/renewables, and water solutions.

NGL Energy Partners LP (NYSE:NGL) hit a 5-year high last week after it was revealed that the company’s director, James Collingsworth, has made a significant investment in NGL by purchasing 100,000 shares of its common stock, valued at around $580,000. The move reflected the director’s confidence in the company’s future success, boosting investor confidence.

So the recent fall in share price could be due to investors cashing in their profits. However, despite the downturn, the NGL stock has surged by almost 37% over the last six months.

4. Evolution Petroleum Corporation (NYSEAMERICAN:EPM)

Share Price Decline Between Sep 18 – Sep 25: 9.69%

Evolution Petroleum Corporation (NYSEAMERICAN:EPM) is an independent energy company that engages in the ownership of and investment in onshore oil and natural gas properties in the United States.

Evolution Petroleum Corporation (NYSEAMERICAN:EPM) shot up earlier this month after the company reported strong results for its Q4 2025, beating expectations in both earnings and revenue. Moreover, Evolutions generated near-record total production in FY 2025, averaging 7,074 BOEPD, up 4% from the previous year.

Evolution Petroleum Corporation (NYSEAMERICAN:EPM) also remains committed to shareholders and declared its 13th consecutive dividend of $0.12 per share, payable on September 30, 2025. So the recent slump in the share price could be due to profit-taking by investors.

3. Hess Midstream LP (NYSE:HESM)

Share Price Decline Between Sep 18 – Sep 25: 11.7%

Hess Midstream LP (NYSE:HESM) is a fee-based, growth-oriented midstream company that owns, operates, develops, and acquires a diverse set of midstream assets to provide services to Chevron, its subsidiaries, and third-party customers.

Hess Midstream LP (NYSE:HESM) fell after the company’s recently updated guidance reflected an expected reduction in Bakken rig activity by Chevron from four to three drilling rigs beginning in Q4 2025. The midstream operator announced that it expects long-term growth in gas throughput volumes in the Bakken through at least 2027, while oil throughput volumes are now anticipated to plateau in 2026 as a result of lower planned rig activity.

Hess Midstream LP (NYSE:HESM) also took a hit when Wells Fargo recently downgraded the stock from ‘Overweight’ to ‘Equal Weight’ with a price target of $39, down from $48. According to the analyst, Chevron’s decision to move to three rigs in the Bakken significantly reduces Hess Midstream’s EBITDA growth and capital return.

2. Sable Offshore Corp. (NYSE:SOC) 

Share Price Decline Between Sep 18 – Sep 25: 16.25%

Sable Offshore Corp. (NYSE:SOC) is a Houston-based independent upstream company focused on developing the prolific Santa Ynez Unit in federal waters offshore California.

Sable Offshore Corp. (NYSE:SOC) plummeted this week after the Santa Barbara County district attorney accused it of flouting state laws that protect streams and wetlands, adding to the company’s legal complications as it works to restart the offshore operations at three oil platforms it now owns. Sable has denied the prosecutors’ allegations, calling them ‘politically motivated’ and ‘extremely misleading’.

Sable Offshore Corp. (NYSE:SOC) also suffered a blow earlier this month when California’s Governor Newsom proposed a legislative package that would impose further restrictions on the state’s offshore oil industry, directly impacting the company’s efforts to reactivate a pipeline off the coast of Santa Barbara County.

1. Cosan S.A. (NYSE:CSAN) 

Share Price Decline Between Sep 18 – Sep 25: 20.92%

Topping our list of Energy Stocks that Lost This Week is Cosan S.A. (NYSE:CSAN), which engages in the fuel distribution business with operations in Brazil, England, France, Spain, Portugal, Argentina, Bolivia, Uruguay, Paraguay, the United States, Asia, and internationally.

Cosan S.A. (NYSE:CSAN) sank after the company announced plans to raise as much as 10 billion Brazilian reais, around $1.9 billion, in a public offering to help reduce its mounting debt.

According to analysts at Citi, the public offering implies a 40-50% dilution to current shareholders but should be positive as Cosan S.A. (NYSE:CSAN) would enter ‘a new phase, which should be marked by deleveraging in the holding company’.

Following the recent downturn, the share price of Cosan S.A. (NYSE:CSAN) has dropped by 51% over the last year.

While we acknowledge the potential of CSAN to grow, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and have limited downside risk. If you are looking for an AI stock that is more promising than CSAN and that has 100x upside potential, check out our report about this cheapest AI stock.
