Why is Flowserve Corporation (FLS) stock moving?

Flowserve beat Q3 2026 adjusted EPS estimates ($1.07 vs $0.98), raised the low end of its full-year adjusted EPS guidance, and reported a record $3.5B backlog up 20% year over year, with adjusted operating margin up 170 basis points. The company cut its full-year organic sales outlook to down 2.5% to down 1.5%, citing Middle East disruption that is expected to weigh on Q4 sales, which is the main counterweight. The stock jumped 11.9% on Oct 29 from $71.81 to $80.35 on about 3.7M shares, roughly double the recent daily average, and kept rising to a high of $86.46 on Nov 9. RBC's price target increase to $98 from $88 with an Outperform rating adds analyst support. Shares closed at $85.66 on Nov 10, near the recent high, after a pullback to $78.04 on Nov 5. Volume on Nov 10 was lower, at about 1.0M shares. Much of the post-earnings gain is already priced in, so the near-term path depends on whether Q4 sales hold up despite the Middle East headwinds.
