Constellation Energy stock (ISIN US21037T1097) is drawing investor attention as the company announced a 15-year renewable energy agreement with Toyota Motor North America and entered a long-term power purchase agreement for over 115 megawatts of solar capacity as of September 21, 2026, underscoring its strategy to lock in premium, long-duration clean power contracts.

Toyota solar agreement and long-term PPA

According to Constellation on September 21, 2026, the company and Toyota Motor North America signed a 15-year renewable energy agreement under which Toyota will receive renewable energy certificates generated by the Milano Solar project via Constellation's Offsite Renewable CORe solutions product.

Backed by Toyota's long-term commitment, Constellation has entered into a separate long-term power purchase agreement with Ferrovial's Milano Solar project for more than 115 megawatts of solar capacity, representing approximately 246,000 megawatt-hours of renewable energy generation annually, providing a sizeable contracted volume that complements its nuclear fleet and adds visible cash flow over the term of the deal.

Upgraded guidance and recent earnings momentum

Management has paired the contract activity with stronger financial guidance: according to an analysis citing company commentary on Constellation's latest outlook, the group raised its 2026 full-year adjusted operating earnings guidance to a range of USD 11.50 to USD 12.50 per share, with the increase reflecting new long-term nuclear supply agreements totaling about 920 megawatts with investment-grade customers.

For the most recent quarter, one detailed review of the company’s results reports that Constellation delivered adjusted earnings per share of USD 2.55 in the second quarter of 2026, roughly 9.4 percent above the consensus expectation of USD 2.33, while revenue reached about USD 7.5 billion, up 23.0 percent year over year, underlining how higher power prices and contracted volumes are translating into double-digit top-line growth.

Analyst targets and valuation backdrop

Morgan Stanley has recently reiterated its positive stance on Constellation Energy stock: as summarized by a news overview, the bank maintained an Overweight rating and lifted its 12-month price target from USD 364 to USD 369, implying substantial upside from the current share price and reflecting confidence in the company’s ability to monetize its nuclear and renewable portfolio.

In parallel, a broader analyst consensus compiled by a research portal points to an average 12-month price target of about USD 348.55 for Constellation Energy stock and tracks roughly 22 analysts covering the name, with a distribution skewed toward Buy and Outperform recommendations and no Sell ratings, suggesting that Wall Street generally views the current pullback as an opportunity rather than a structural concern.

Stock performance and recent volatility

Recent trading has been volatile: an in-depth performance review notes that Constellation Energy stock fell 13 percent between September 9 and September 18, 2026, sliding from USD 293.90 to a close of USD 254.71 as shares tied to its Calpine-related acquisition came to market and rising bond yields pressured nuclear and utility names across the sector.

The same analysis indicates that at the USD 254.71 closing level the stock stood roughly 37 percent below the mean analyst price target of USD 349 tracked by the portal, highlighting the gap between current market pricing and the Street's valuation and giving investors a quantified sense of the potential re-rating if earnings and cash flows continue to grow in line with guidance.

Position among nuclear and clean power peers

Context from sector-focused commentary frames Constellation as one of the largest operators of nuclear power plants in the United States and emphasizes that its investment case rests more on its nuclear fleet and long-term power contracts than on headline-grabbing artificial-intelligence narratives, a distinction that matters as data-center demand raises the strategic value of firm, zero-emission baseload power.

One comparative piece notes that for investors bullish on nuclear energy, Constellation Energy stock has pulled back more than 30 percent from its 52-week high while still delivering year-over-year sales growth of 23.0 percent and sustaining an 11.1 percent net profit margin on trailing 12-month revenue of USD 31.3 billion, illustrating how the company combines growth, profitability and exposure to structural decarbonization trends.

Constellation Energy stock price and key data

As of the last completed trading day cited in recent overviews, Constellation Energy stock closed at USD 254.71 on the Nasdaq, down 13 percent from USD 293.90 on September 9, 2026, and more than 30 percent below its 52-week high, while analysts’ average 12-month target of about USD 348.55 indicates a roughly 37 percent upside from that closing level if the shares were to revert to consensus valuation.
