AI Insight: OSK Financial Trends

Q1 2026 operating income collapsed to $82M — the lowest in the visible 8-quarter series — even as revenue held near year-ago levels.

• Operating income fell sharply to $82M in Q1 2026 from $175M in Q1 2025, implying operating margin compressed by roughly half year-over-year.

• Total debt declined from $1,636M in Q2 2024 to $1,147M in Q1 2026, a meaningful $489M reduction over seven quarters.

• Equity grew steadily from $3,925M in Q2 2024 to a peak of $4,537M in Q3 2025 before dipping slightly to $4,466M in Q1 2026.

⚠ Operating cash flow turned negative at -$161M in Q1 2026; Q1 2025 was also negative at -$395M, suggesting persistent seasonal working-capital drag.

⚠ Revenue has trended down from $2,847M in Q2 2024 to $2,318M in Q1 2026 — monitor whether the top-line decline stabilizes or deepens.

AI Insight: OSK Ratio Trends

OSK's Q1 2026 operating margin collapsed to 3.5% — the lowest in the visible dataset — as ROIC cratered to 5.8%, signaling a sharp near-term profitability deterioration.

• Operating margin fell from 10.7% in Q2 2025 to 3.5% in Q1 2026, a 720bp decline over three quarters.

• ROIC dropped from 19.6% in Q2 2025 to 5.8% in Q1 2026, the steepest single-cycle decline in the dataset.

• Leverage (D/E) improved from 0.42 in Q2 2024 to 0.26 in Q1 2026, a meaningful balance-sheet positive.

⚠ Q1 2025 also showed a margin trough (7.6% OpMargin, 12.3% ROIC) — watch whether Q1 2026's 3.5% reflects seasonality or structural deterioration.

⚠ TTM ROIC of 15.1% masks the Q1 2026 single-quarter 5.8% reading — sequential recovery in Q2 2026 is the critical near-term inflection.
