Otter Tail reports Q3 2026 earnings miss and affirms 2026 EPS guidance midpoint

Otter Tail Corp. posted third‑quarter 2026 diluted earnings per share of $1.41, down 24% from $1.86 a year earlier, and revenue of $320.5 million, a 1.6% year‑over‑year decline. The company affirmed the midpoint of its full‑year adjusted EPS guidance at $5.88 and narrowed the adjusted EPS range to $5.73‑$6.03. Segment performance showed electric sales up 0.9%, manufacturing volumes up 13%, while plastics volumes fell 5%.

The earnings miss triggered a 7.74% after‑hours share decline, reflecting investor concern over the plastics weakness. The unchanged guidance signals that full‑year earnings expectations remain stable despite the quarterly shortfall.
