Why Guidewire Software, Inc. (GWRE) Stock Fell 19.9% on Sep 4, 2026
The clearest new catalyst: Fiscal Q4 2026 beat (reported Sep 3, after close).
Why did GWRE stock fall?
Guidewire fell 19.93% to $162.42 on Friday, September 4, 2026 after its fiscal Q4 2026 report (released after Thursday's close). The quarter beat — revenue $411.1M (vs ~$402.7M), non-GAAP EPS $0.99 (vs $0.93), ARR $1.242B (+19% constant currency) — but soft fiscal Q1 2027 revenue guidance ($372-378M vs ~$387M consensus) and an ARR-growth step-down to ~18% drove the sell-off in a highly valued stock.
- Fiscal Q4 2026 beat (reported Sep 3, after close): Guidewire reported after Thursday's close (4:05 p.m. ET Sep 3): revenue of $411.1 million beat the ~$402.7 million consensus, non-GAAP EPS was $0.99 versus $0.93 expected, and ARR reached $1.242 billion, up 19% in constant currency. So September 4 was the first full session reacting to a quarter that was, on its own, a beat.
- Soft near-term guidance drove the drop: Fiscal Q1 2027 revenue guidance of $372-378 million came in clearly below the roughly $387 million consensus, and FY2027 ARR guidance of $1.450-1.460 billion implied about 18% growth, down from 19%. That weaker near-term trajectory and ARR-growth step-down — against elevated expectations in a highly valued stock — was widely cited as the reason for the sell-off.
- Full-year revenue guide was NOT the problem: Importantly, FY2027 total-revenue guidance of $1.707-1.727 billion was actually slightly above the cited ~$1.701 billion consensus, so this was not a case of the full-year revenue outlook missing. The disappointment was specifically the Q1 revenue guide and the ARR-growth deceleration.
How the story developed
- September 3, 2026 (4:05 p.m. ET)Guidewire reports fiscal Q4 2026 (beat) but guides fiscal Q1 2027 revenue and FY2027 ARR growth below elevated expectations.
- September 4, 2026GWRE closes down 19.93% at $162.42 as the soft near-term guidance overshadows the Q4 beat.
What it could mean for GWRE investors
The constructive case
- The quarter itself beat on revenue, EPS and ARR (+19% cc), and full-year revenue guidance was slightly above consensus — the underlying franchise is intact.
- A reset in a high-multiple name can relieve valuation pressure without a change in the long-term cloud-migration story.
The cautious case & what could invalidate it
- An ARR-growth step-down to ~18% raises the question of whether the growth rate is decelerating structurally.
- The stock's premium valuation leaves little room for soft near-term guidance, as the ~20% drop shows.
- Near-term (Q1) revenue softness could persist if deal timing or cloud-migration cadence slips.

Show the initial intraday note
Guidewire Software, Inc. (GWRE) fell 19.93% from a prior close of $202.86 to $162.42 on Friday, September 4, 2026, the first full session after it reported fiscal Q4 2026 results following Thursday's close. The quarter was a genuine beat — revenue of $411.1 million (versus about $402.7 million expected), non-GAAP EPS of $0.99 (versus $0.93), and annual recurring revenue of $1.242 billion, up 19% in constant currency — but the sell-off was driven by soft near-term guidance: fiscal Q1 2027 revenue guidance of $372-378 million came in below the roughly $387 million consensus, and FY2027 ARR guidance implied about 18% growth, a step down from 19%.
What to watch next: The debate is whether the ARR-growth deceleration (to ~18%) is a blip or a trend, so watch quarterly ARR adds, the cloud-migration pace and whether management re-accelerates. Note the full-year revenue guide was actually fine — it was the near-term (Q1) softness and the growth-rate step-down that spooked a richly valued stock.
