What critics are saying

  • Integration risk remains after 2025 merger; missteps would slow client delivery through 2026.
  • Private-equity ownership under OceanSound pressures margins, leverage, and resale before 2028.
  • Federal and state infrastructure spending downturns would crush backlog and trigger layoffs.

What makes Gannett Fleming unique

  • April 2025 rebrand to GFT unified Gannett Fleming, TranSystems, and five acquisitions.
