AI Insight: NPO Financial Trends

Enpro's Q1 2026 revenue hit a new 8-quarter high of $303M while total debt, despite a Q4 2025 spike, is trending down from $662M to $605M.

• Revenue grew steadily from $258M in Q4 2024 to $303M in Q1 2026, the highest level in the observed period.

• Total debt declined from $662M in Q2 2024 to $445M in Q3 2025, though it rebounded sharply to $656M in Q4 2025 before falling to $605M in Q1 2026.

• Equity steadily expanded from $1,430M in Q2 2024 to $1,563M in Q1 2026, reflecting consistent book-value accumulation.

• Operating cash flow improved materially, rising from $21M in Q1 2025 to $65M in Q3 2025, with Q1 2026 at $40M.

⚠ Net income swung to -$32M in Q4 2025 despite positive op income of $33M — a large below-the-line charge warrants scrutiny.

⚠ Total debt jumped from $445M in Q3 2025 back to $656M in Q4 2025, reversing several quarters of deleveraging progress.

⚠ Op income has not recovered to Q2 2024's $48M peak; Q1 2026 at $44M shows partial but incomplete margin recovery.

AI Insight: NPO Ratio Trends

A Q4 2025 earnings shock — NPM crashing to -10.8% — drags TTM profitability well below recent quarterly run-rates, masking an otherwise stabilizing margin profile.

• Operating margin has oscillated between 11.2% and 17.6% since Q2 2024, with no sustained expansion trend.

• D/E improved meaningfully from 0.46 in Q2 2024 to 0.29 in Q3 2025, before ticking back up to 0.42 in Q4 2025.

• ROIC recovered to 8.0% in Q1 2026 after bottoming at 6.0% in Q4 2025, but remains below Q2 2025's 9.3% peak.

• Q4 2025 NPM collapsed to -10.8%, pulling TTM NPM down to just 3.7% versus 9.0% in Q1 2026.

⚠ The Q4 2025 NPM plunge to -10.8% warrants scrutiny — confirm whether one-off charges drove it or reflect structural deterioration.

⚠ D/E rebounded to 0.42 in Q4 2025 after reaching 0.29 in Q3 2025 — monitor whether leverage re-accumulates.

⚠ Q1 2026 operating margin of 14.4% shows recovery, but sustaining above 15% remains unproven over multiple quarters.
