Otter Tail enters its third-quarter report with an awkward mix of good news and arithmetic. Management raised its full-year outlook last quarter after its plastics business sold more pipe than ever and price erosion eased. That same strength came partly from customers buying ahead of resin price hikes, which means some third-quarter demand was spent early. The report due after the close on November 2 should show whether the raised guidance was built on durable improvement or on a one-quarter surge.

The Street expects earnings of $1.57 per share on revenue of about $335.7 million. That implies a 15.6% drop from the $1.86 earned a year ago, even as sales rise a modest 3.1%. The gap between flat-to-higher revenue and sharply lower profit is the plastics normalization story in a nutshell. Volumes are holding up, but PVC pipe prices remain below last year's elevated levels, and that segment is still expected to step down through 2027 toward a normalized $45 million to $50 million in 2028. The forecast also sits a little below the $1.66 the company earned in the second quarter, consistent with management's warning that second-half pipe volumes would be softer.

Guidance gives important context. Otter Tail lifted its 2026 adjusted EPS range to $5.68 to $6.08 from $5.22 to $5.62, its first net raise since introducing the outlook. The full-year consensus of $5.54 sits below the bottom of that new range. Part of the gap may reflect differing treatment of the $103.5 million antitrust settlement, so the figures are not perfectly comparable. Still, the Street looks cautious relative to management, and a quarter that keeps the company on track for its range would leave room for estimates to rise.

Pricing is the swing factor. PVC price declines narrowed to 14% year over year in the second quarter from 19% in the first, and average selling prices actually rose sequentially. Management now assumes a roughly 15% full-year decline rather than 20%. If third-quarter prices hold near second-quarter levels, that assumption looks conservative and the plastics glide path looks gentler than feared. A renewed slide once the pull-forward fades would undercut the main reason for the raise. Volume should be read with that context: a year-over-year dip is expected and not alarming on its own, provided management still sees annual volume roughly unchanged.

The other segments need to carry their share. Manufacturing earnings jumped 38% last quarter on better mix, and management described conditions improving in construction, RV and lawn and garden, a notable shift from its earlier expectation of a downturn lasting through most of 2026. Continued gains would confirm that change in tone, while agriculture remains a known soft spot. The electric utility is guided to 14% earnings growth, and summer results will show whether that pace is intact. Progress on the Minnesota rate case, now seeking $42.3 million on a longer schedule, matters too, as do updates on the 1,400-megawatt large-load pipeline and the new large-load tariffs filed in three states. Higher corporate costs tied to lower investment income and the settlement are an expected drag rather than a surprise.

Sentiment has warmed but remains slightly bearish, improving to a reading of -0.063 from -0.146 before the last report. Shares have gained 2.6% since then while the S&P 500 was flat, and the stock trades above its 200-day moving average in the upper half of its post-earnings range. At about 5% below that range's high, it is not yet testing a breakout. The central question is simple: can PVC pricing stay firm after the buying rush, so the raised outlook looks like the start of a recovery rather than a temporary lift?
