Shares of Spire Inc. (SR) plunged 5.13% in pre-market trading on Wednesday after the natural gas company reported second-quarter earnings that fell short of analyst estimates.

For the fiscal second quarter ended March 31, Spire posted adjusted earnings per share of $3.60, missing the average analyst estimate of $3.67. Revenue for the quarter came in at $1.05 billion, significantly below the $1.24 billion analysts were expecting.

Despite the earnings miss, Spire reaffirmed its full-year 2025 adjusted earnings guidance range of $4.40 to $4.60 per share. The company cited higher earnings at its Gas Utility segment, driven by new rates and increased usage at Spire Missouri. However, this was partially offset by lower Gas Marketing earnings due to reduced market volatility. Spire's CEO Scott Doyle emphasized the company's "continued commitment to operational excellence and disciplined execution of our strategy" in the earnings release.
