Can Constellation Energy's Contracts Power a Stock Rebound?

Key Points

• Constellation Energy raised its 2026 earnings guidance after adjusted third-quarter earnings rose 66%.
• Long-term power agreements totaling 8,500 megawatts provide greater earnings visibility as demand from data centers increases.
• Valuation concerns, regulatory uncertainty, and the timing of future contract revenue remain risks for investors.

Constellation Energy Corporation NASDAQ: CEG recently posted a 66% increase in third-quarter adjusted earnings to $5.06 per share on $9.55 billion in revenue.

Management responded by narrowing and raising its full-year guidance. Despite the solid quarter, shares remain roughly 28% below their 52-week high, trading near $275.

Election-related policy concerns and recent management commentary regarding untapped grid capacity have tempered near-term power scarcity expectations.

This dynamic leaves investors wondering whether Constellation Energy's expanding portfolio of long-term power contracts can justify its current valuation, or whether patience is required until the next growth phase materializes.

The Gridlock in Utility Valuations

The third-quarter results highlighted steady operational execution. Adjusted operating earnings reached $5.06 per share, up from $3.04 a year earlier and beating consensus estimates of around $3.90. Revenue climbed 45% year-over-year. Following the release, management updated full-year 2026 adjusted earnings guidance to a range of $12.50 to $12.80 per share, establishing a new floor at the top of its previous guidance.

Constellation Energy's stock price initially gained over 10% following the earnings release but cooled shortly after. The broader context involves the physical realities of the U.S. power grid. Management recently noted that the U.S. power system could have another six to seven years' worth of underutilized generation capacity. While this latent capacity offers a near-term solution for rising electricity needs, it also dials back the urgency of the power-scarcity narrative that drove utility valuations higher earlier this year.

Coupled with regulatory ambiguity surrounding co-located data centers, these factors have created a valuation overhang. Co-location involves building large data centers directly adjacent to power plants, allowing technology companies to bypass broader transmission network upgrades. The Federal Energy Regulatory Commission is reviewing how to allocate the costs of these setups among everyday ratepayers and corporate users. Until regulators provide a clear framework, investors are currently weighing the benefits of steady operational execution against a shifting macroeconomic and regulatory landscape.

Generating Momentum Through Nuclear Consistency

Reviewing the quarterly drivers, Calpine's integration added significant scale to the generation portfolio. The acquisition contributed about $3.38 billion in third-quarter revenue, equating to $1.93 billion net of purchased power and fuel. This natural gas and geothermal fleet performed well during its seasonally strongest summer quarter.

Simultaneously, the nuclear fleet delivered high reliability. Constellation Energy logged a 99.2% capacity factor during the peak summer months of June through August, operating without a single unplanned outage day. This consistency allowed Constellation Energy to capture higher wholesale power and capacity prices in the regional market, which offset lower nuclear production tax credit (PTC) receipts.

The PTC acts as a revenue floor for clean energy producers. When market prices rise above that floor, Constellation Energy captures the upside, effectively trading federal tax credits for higher open-market revenues.

Wiring Up Long-Term Visibility With 8,500 Megawatts

The long-term investment case leans heavily on cash flow visibility. Constellation Energy signed over 8,500 megawatts of long-term power agreements this year. Technology hyperscalers like Alphabet Inc. NASDAQ: GOOGL, Amazon.com, Inc. NASDAQ: AMZN, and Microsoft Corporation NASDAQ: MSFT are increasingly seeking reliable, carbon-free energy to power data centers. Recent 20-year agreements with Alphabet and Amazon contribute to a broader contract portfolio expected to cover roughly 45% of Constellation Energy's clean baseload generation by 2032, securing pricing well above the inflation-linked tax credit floor.

To capture additional demand, management recently introduced the Peak+ solution. This model pairs available nuclear output with capacity solutions such as demand response and battery storage to alleviate peak grid constraints. The first 20-year, 270-megawatt contract under this structure captures premium pricing without the interconnection delays typically associated with building new infrastructure.

The capital structure supporting this expansion also received a boost. A conditional $5.0 billion financing commitment from the Department of Energy could help lower borrowing costs for upcoming nuclear uprate projects if finalized, allowing Constellation Energy to add new capacity efficiently and cost-effectively.

Weighing the Balance Sheet Against Industry Rivals

Constellation Energy currently trades near 21x forward earnings. This represents a notable premium compared to independent power producers like Vistra Corp. NYSE: VST, which trades around 13x forward earnings, and Talen Energy Corporation NASDAQ: TLN, also trading close 13x forward earnings.

Part of the reason for this premium is balance sheet health. Constellation Energy maintains a conservative 0.58 debt-to-equity ratio. Liquidity is also set to expand. To satisfy regulatory requirements from the Calpine acquisition, Constellation Energy is divesting several natural gas plants to LS Power for about $5 billion. These incoming cash proceeds, expected by year-end subject to regulatory approvals and closing conditions, provide significant capital flexibility.

Management is strategically recycling this capital. The pending $715 million acquisition of the Rhode Island State Energy Center carries an effective net cost closer to $580 million after expected first-year tax benefits. This translates to an acquisition cost of roughly $952 per kilowatt, a steep discount compared to the estimated $3,000 per kilowatt required to build a new combined-cycle gas plant from scratch.

While 2027 appears to be a transitional bridge year with modest consensus earnings growth projected before major hyperscaler contracts ramp up in 2028, the underlying demand fundamentals remain intact. The U.S. Energy Information Administration continues to forecast record electricity demand through 2027, driven largely by commercial data center consumption.

Unmodeled Catalysts Approaching the Fourth Quarter

Looking ahead, the current valuation may not fully reflect recent commercial execution. Earlier baseline growth targets did not account for the roughly 5,500 megawatts of premium contracts signed since March. Those early models excluded the aggressive execution of the share repurchase program, which has already retired about 11 million shares over the past seven months.

With approximately $5 billion in divestiture cash potentially arriving by year-end, the upcoming fourth-quarter earnings call could serve as a catalyst. Management plans to provide an updated capital allocation framework, which could feature an expanded buyback authorization and refreshed growth targets through 2030. Clarity from the Federal Energy Regulatory Commission regarding co-location tariff rules is also anticipated in the first half of 2027, which could resolve lingering regulatory uncertainty.

Investors may want to add Constellation Energy to their watchlist and monitor the upcoming fourth-quarter guidance reset, as these fundamental updates could provide the visibility needed to support long-term capital appreciation.
