Longleaf Partners Fund stated the following regarding Fortune Brands Innovations, Inc. (NYSE:FBIN) in its Q1 2026 investor letter:
“Fortune Brands Innovations, Inc. (NYSE:FBIN) – Building products company Fortune Brands saw its stock price decline due to near-term earnings weakness and leadership uncertainty. 4Q25 results missed expectations due to weakening markets. Guidance for 2026 was lower than expectations due to market demand remaining soft and likely some internal execution missteps. Nick Fink resigned as CEO to take the CEO spot at Constellation Brands, and the board too quickly announced Amit Banati, a current board member, as the new CEO. Ed Garden of Garden Investments subsequently disclosed a substantial position in FBIN stock and publicly implored the board to reconsider their CEO decision and conduct a national search. While disruptive in the near term, this led to multiple benefits including improved governance changes at the board level, a new CEO search, and Ed Garden taking a board seat. We have been in constructive dialog with all parties and are glad that these strong brands will receive renewed leadership going forward.”
