Celestica Inc. (CLS) Cash Flow Statement

The OCF/NI ratio swung from 0.47 in 2025Q3 to 1.68 in 2026Q1, indicating that working capital swings, not earnings quality, drive cash generation. The positive working capital contribution of $108.6M in 2026Q2 suggests efficient collections and inventory management, but the negative swings in prior quarters highlight the lumpy nature of cash conversion in a high-growth EMS model.

The FCF margin trajectory is positive, yet the absolute FCF of $147.1M in 2026Q2 is modest relative to net income of $368.8M, reflecting heavy reinvestment. The capex-to-revenue ratio jumped from 1.5% in 2024Q2 to 5.6% in 2026Q2, indicating that management is funding AI capacity expansion ahead of demand, which may pressure near-term FCF but supports the growth narrative.

The sharp increase in capex suggests a shift from maintenance to growth-oriented spending, likely tied to hyperscaler infrastructure buildouts. While this elevates capital intensity, the low debt-to-equity ratio of 0.41% implies the company can fund this internally, but investors should monitor whether this investment translates into sustained revenue growth or leads to overcapacity if demand normalizes.

The positive working capital contributions in recent quarters suggest that Celestica is collecting receivables faster and managing inventory efficiently, likely due to strong demand and pass-through pricing. However, the negative swings in earlier quarters highlight the risk of inventory build-up if hyperscaler orders pause, which could reverse cash generation and pressure liquidity.

The buyback activity is modest relative to operating cash flow, suggesting management is balancing shareholder returns with reinvestment. The absence of dividends and the small acquisition activity (only $48.8K in 2026Q2) indicate a disciplined approach, but the increasing capex may limit future buyback capacity if cash generation does not keep pace.
