AI Insight: ROCK Financial Trends
A $1.2B debt load appearing in Q1 2026 alongside a $4M operating loss and negative $41M operating cash flow marks a sharp structural break from prior debt-free operations.
• Total debt surged from $0 in Q4 2025 to $1,221M in Q1 2026, the first debt on the balance sheet in the observed period.
• Operating income turned negative at -$4M in Q1 2026, versus +$26M in Q1 2025, a $30M year-over-year deterioration.
• Net income has been negative three of the last four quarters, including -$89M in Q3 2025 and -$67M in Q1 2026.
• Equity declined from a peak of $1,048M in Q4 2024 to $881M in Q1 2026, a $167M erosion over five quarters.
⚠ With $1,221M debt now on the balance sheet and negative operating cash flow of -$41M in Q1 2026, debt service capacity is a key concern.
⚠ Revenue of $356M in Q1 2026 is the highest Q1 in the dataset, suggesting potential acquisition-driven growth — monitor integration costs.
⚠ Recurring net losses despite positive prior-year profitability may signal goodwill impairment or restructuring charges — watch for disclosure.
AI Insight: ROCK Ratio Trends
A large impairment or one-off charge has driven Gibraltar Industries into negative ROIC (-0.9%) and operating loss (-1.2%) in Q1 2026, erasing two years of solid profitability.
• Operating margin collapsed from 16.0% in Q2 2025 to -1.2% in Q1 2026, the first negative quarterly operating margin in the visible dataset.
• Net profit margin swung to -18.9% in Q1 2026 and -28.6% in Q3 2025, signaling recurring large below-the-line charges weighing on reported earnings.
• D/E ratio jumped from 0.00 across all prior quarters to 1.39 on the TTM and Q1 2026 balance sheet, indicating significant new debt taken on.
• ROIC turned negative at -0.9% in Q1 2026 after holding at 16–19% range through mid-2025, reflecting rapid deterioration in capital deployment efficiency.
⚠ Nature and recurrence of charges driving negative NPM in Q3 2025 (-28.6%) and Q1 2026 (-18.9%) — goodwill impairment or restructuring must be confirmed.
⚠ D/E rising from 0.00 to 1.39 warrants monitoring of covenant compliance and interest coverage as operating income turns negative.
⚠ Whether operating margin can recover toward the 16–17% range seen in Q2–Q3 2024 once one-off charges clear is the key profitability inflection to track.
