The sequential deterioration in gross margin from 19.2% to 16.5% over four quarters suggests that input cost inflation and mix shifts are not being fully offset by price increases. Operating margin at 8.3% in 2026Q2 is below the 10.9% peak in 2025Q2, implying negative operating leverage as SG&A costs remain sticky. This margin compression appears structural rather than temporary, given the persistence across multiple quarters and the guidance cut, warranting close monitoring of cost pass-through ability.

The downward trend in ROIC and ROE, despite stable leverage, suggests that profitability is eroding faster than capital efficiency improvements. The 2025Q2 peak of 4.0% ROIC and 4.7% ROE marked the high point, after which both metrics have declined, reflecting margin compression and possibly higher working capital intensity. This decay in returns may indicate that the company is not compounding capital effectively, and investors should assess whether the EV transition and defense contract losses will further pressure returns.

The CCC has remained elevated around 126-150 days over the past year, with DSO and DIO both increasing, suggesting that receivables and inventory are tying up more cash. The DPO of 37 days in 2026Q2 is lower than the 50 days seen in 2025Q1, indicating that Oshkosh is paying suppliers faster, which may strain liquidity. This lengthening cycle, combined with negative FCF in some quarters, highlights working capital management as a key area to watch, especially given the lumpy government contracts.

Although D/E remains low at 0.24, the increase in D/EBITDA to 3.61x and the decline in interest coverage to 8.16x suggest that EBITDA is shrinking relative to debt, reducing the cushion for interest payments. The 2026Q1 spike in D/EBITDA to 8.04x and interest coverage of only 2.84x highlights the volatility in earnings, which could strain debt service if the trend persists. The balance sheet appears adequate, but the declining coverage warrants monitoring, especially if the defense revenue cliff materializes.

The current ratio has strengthened over the past year, reaching 1.72, suggesting improved short-term solvency, but the quick ratio of 0.96 indicates that a significant portion of current assets is tied up in inventory. This inventory dependence could be problematic if demand softens or if there are supply chain disruptions, as converting inventory to cash may take longer. The liquidity position appears adequate under normal conditions, but stress scenarios involving a sharp downturn in Access Equipment could test the buffer.
