AI Insight: ULBI Financial Trends

Ultralife's operating income swung from +$4M in Q2 2024 to -$11M in Q4 2025, eroding equity and signaling a sharp profitability deterioration.

• Operating income collapsed from $4M in Q2 2024 to -$11M in Q4 2025, marking a stark reversal over six quarters.

• Total debt surged from $8M in Q3 2024 to $58M in Q4 2024, remaining elevated at $48M in Q1 2026.

• Equity eroded from $138M in Q2 2025 to $130M in Q1 2026, reflecting cumulative net losses.

• Operating cash flow has been near zero for three consecutive quarters (Q3 2025–Q1 2026), ranging from $0M to $2M.

⚠ Q4 2025 net loss of -$7M and op loss of -$11M are outlier magnitudes — monitor whether Q1 2026 breakeven holds.

⚠ Debt remains ~$50M versus near-zero pre-acquisition levels; debt reduction pace is critical to watch.

⚠ Revenue has held $43M–$51M across all eight quarters — stability here is the one constructive data point.

AI Insight: ULBI Ratio Trends

A severe Q4 2025 loss dragged TTM profitability deeply negative, erasing the gains seen through mid-2025.

• Operating margin collapsed to -21.9% in Q4 2025 from +4.7% in Q2 2025, pulling TTM OpMargin to -5.1%.

• ROIC swung from a peak of 10.8% in Q2 2024 to -23.6% in Q4 2025, signaling capital destruction.

• Q1 2026 OpMargin partially recovered to -0.4% from -21.9% in Q4 2025, suggesting the Q4 hit may be partly one-off.

• D/E ratio rose sharply from 0.06 in Q3 2024 to 0.43 in Q4 2024 and remains elevated at 0.37 in Q1 2026.

⚠ Q4 2025's -21.9% OpMargin looks like a one-off; confirm whether Q1 2026's near-breakeven reflects genuine recovery.

⚠ D/E jumped from near-zero (0.06) to ~0.38 range — monitor whether leverage stabilizes or continues climbing.

⚠ ROE turned deeply negative at -22.8% in Q4 2025; sustained losses risk further balance sheet erosion.
