Constellation Energy stock tracks a raised 2026 earnings guide

Constellation Energy stock stood at USD 263.88 on Nasdaq on September 23, 2026, with a daily gain of 0.16 percent. The move came as the company entered the market's next test with higher 2026 earnings guidance and a sharp year-over-year comparison in adjusted operating EPS.

Guidance rises after Q2 results

Constellation Energy reported USD 7.504 billion in second quarter 2026 revenue, while consolidated net income reached USD 502 million. GAAP earnings were USD 1.42 per diluted share, according to Yahoo Finance.

The more important operating figure was adjusted EPS of USD 2.55 in Q2/2026. That was USD 0.64 above the USD 1.91 reported for Q2/2025, a 33.5 percent increase that management attributed to the Calpine combination, higher PJM capacity prices and commercial performance.

Midpoint reaches USD 12.00

The company raised its 2026 adjusted operating earnings guidance to USD 11.50-12.50 per share, putting the midpoint at USD 12.00. Yahoo Finance reported that the new midpoint equals the previous top end of the guidance range.

The operating comparison matters because the new guide combines current earnings delivery with expectations for the rest of the year. It also gives the stock a measurable fundamental reference while the share price remains 36.06 percent below its 52-week high of USD 412.70.

Stock remains below yearly high

Constellation Energy's market capitalization was USD 94,759,841,038 as of September 24, 2026. Its 52-week range was USD 228.63 to USD 412.70, so the September 23 price sat closer to the lower end than the peak.

For investors, the central distinction is between reported earnings and the forward guide. Q2 adjusted EPS of USD 2.55 provides the latest operating benchmark, while the USD 11.50-12.50 full-year range defines the earnings path management presented for 2026.
