AI Insight: GFF Financial Trends

Griffon suffered a massive Q2 2025 loss but has stabilized margins and reduced debt by $161M since, though Q1 2026 revenue collapsed 65% sequentially.

• Operating margin rebounded to 17.9% in Q3 2025 and 17.4% in Q4 2025 after collapsing to -20.5% in Q2 2025, signaling operational recovery.

• Total debt declined from $1,545M (Q1 2025) to $1,403M (Q1 2026), a $142M reduction; leverage improving despite equity erosion.

• Q1 2026 revenue of $227M represents 65% sequential drop from Q4 2025's $649M, suggesting material demand contraction or one-time event.

⚠ Q2 2025 net loss of -$120M wiped out equity from $228M to $64M in one quarter; equity recovery to $94M appears fragile.

⚠ Q1 2026 revenue 65% below prior quarter—investigate whether seasonal, divestiture-related, or demand-driven headwind.

AI Insight: GFF Ratio Trends

Operating margin surged to 32.3% in Q1 2026, but profitability metrics collapsed in Q2 2025 and remain volatile; leverage spiked to 22.83x that quarter.

• Operating margin rebounded sharply to 32.3% in Q1 2026 from 17.5% in Q4 2025, highest in dataset.

• Q2 2025 saw catastrophic -20.5% operating margin and -33.1% ROIC; D/E exploded to 22.83x, indicating severe operational distress.

• ROIC recovered to 31.0%–32.0% in Q3–Q4 2025 but fell to 19.6% in Q1 2026, volatile trajectory post-crisis.

⚠ D/E remains elevated at 14.85x (TTM) versus 6.5–7.2x pre-crisis; deleveraging stalled after Q4 2025 improvement.

⚠ Net profit margin highly volatile: -19.6% in Q2 2025, recovered to 9.9% by Q4 2025, slipped to 8.5% in Q1 2026.
