AI Insight: NNBR Financial Trends

NN Inc. remains deeply unprofitable across every quarter while equity has collapsed from $108M to $26M and debt has climbed to a new high of $170M.

• Revenue declined from $123M in Q2 2024 to a trough of $104M in Q3 2025, with only a partial recovery to $118M in Q1 2026.

• Operating income has been negative every quarter, ranging from -$1M to -$17M, with no sign of a sustained improvement.

• Equity eroded from $108M in Q2 2024 to just $26M in Q1 2026, a drop of roughly $82M in six reported quarters.

• Total debt rose from $144M in Q3 2024 to $170M in Q1 2026, even as operating cash flow turned deeply negative at -$9M.

⚠ Equity at $26M versus $170M debt implies a debt-to-equity ratio above 6x — balance sheet stress is acute and accelerating.

⚠ Operating cash flow swung to -$9M in Q1 2026 after a positive $11M in Q3 2025 — cash generation remains highly erratic.

⚠ Revenue uptick to $118M in Q1 2026 is the strongest quarter since Q2 2024 — worth monitoring whether this signals a volume recovery.

AI Insight: NNBR Ratio Trends

NN Inc. remains deeply unprofitable across all metrics, with leverage surging to 6.53x D/E and every return measure negative through Q1 2026.

• Operating margin has been negative every quarter, with severe Q4 dips: -15.8% in Q4 2024 and -10.0% in Q4 2025, suggesting recurring seasonal or restructuring charges.

• D/E ratio has escalated sharply from 1.35x in Q3 2024 to 6.53x in Q1 2026, signaling rapidly deteriorating balance sheet health.

• ROIC worsened from -3.2% in Q2 2024 to -45.4% in Q4 2024, partially recovering to -4.2% in Q1 2026, but has never turned positive.

⚠ Q4 losses (-15.8% OpMargin in 2024, -10.0% in 2025) appear to recur annually — monitor whether Q4 2026 breaks this pattern.

⚠ D/E jumped from 3.12x in Q3 2025 to 6.53x in Q1 2026 — watch for debt covenant risks or potential equity dilution.

⚠ ROE of -104.6% in Q1 2026 implies severely eroded equity base; further losses could push book equity toward zero.
