Fletcher Building shares surged 5.6% to $3.61 after the company upgraded its full-year 2026 operating earnings guidance by 6.4% to a range of $400 million to $403 million.
The positive update provided a significant boost to New Zealand equities, with the S&P/NZX 50 index closing 120.49 points higher at 13,785.67, marking a 0.88% gain for the session.
The guidance increase marks the second consecutive upgrade for the builder, reinforcing investor confidence in the company's ability to navigate current market conditions.
The move suggests underlying strength in the residential construction and materials supply chain, areas that have faced scrutiny amid broader economic uncertainties.
Fletcher's performance helped anchor a broad-based rally in Wellington, where sentiment improved across multiple sectors.
The company's ability to raise forecasts indicates that demand for building materials and services remains robust, countering earlier concerns about a slowdown in the housing market.
