Sonoco Products Company (SON) Cash Flow Statement

The extreme divergence between net income and operating cash flow in 2026Q3 — a $1.0B gap — is consistent with a large non-cash write-down, likely tied to goodwill or intangible assets from the Ball Metal Packaging acquisition, given the 41.7% YoY revenue jump. Historically, OCF has exceeded net income in nearly every period (cumulative OCF of ~$1.4B vs. net income of ~$191M over ten quarters), suggesting earnings quality is structurally low due to heavy D&A (~$1.09B cumulative) and volatile non-cash items. Investors should treat operating cash flow as the more reliable earnings proxy for Sonoco, as reported net income appears unreliable for valuation.

The pattern repeats across fiscal years — 2025Q1 saw a -$393.8M working capital outflow that reversed in 2025Q2 (+$238.9M) — implying a structural seasonal cycle rather than random noise. However, the 2026 swing is roughly 44% larger than 2025, which may indicate that the Ball acquisition's working capital base (metal coil inventory, expanded receivables) has amplified the seasonal amplitude. Analysts should normalize for working capital when assessing underlying operating cash generation, as the swings appear to create false positives (2026Q2 OCF/NI of 2.87) and false negatives (2026Q1 OCF of -$367.9M).

This is a material structural change: the $33.1% CapEx/Rev ratio in 2024Q4 (Ball acquisition close) has compressed to 2.5% in 2026Q3, which could indicate that the metal packaging assets require minimal incremental capital — a positive — or that maintenance spending is being deferred to protect free cash flow amid margin pressure, a negative. With D&A running at ~$130-135M per quarter and CapEx at ~$51-65M, the company is currently replacing depreciated assets at roughly 40-50% of the depreciation charge, which may not be sustainable over a full cycle without eventual catch-up spending. This warrants monitoring as a future cash flow drag.

The persistent gap confirms that Sonoco's accounting earnings systematically understate cash generation due to the capital-intensive nature of its integrated paperboard and metal packaging operations. The $732.1M loss in 2026Q3 is the largest single contributor to this divergence, but even excluding that outlier, operating cash flow exceeded net income in eight of nine remaining periods. This divergence suggests the market may be undervaluing Sonoco's cash flow capacity if it relies on reported earnings multiples, though the sustainability of that cash flow depends on whether capex normalization occurs.

Excluding the 2024Q4 acquisition quarter (74.4% FCF margin) and the working-capital-distorted 2026Q1 (-25.5%), the underlying FCF margin has improved from ~1-10% in 2024 to ~11-12% in 2026, a level that compares favorably to Sealed Air (8.6%) and Packaging Corp of America (7.8%). However, this improvement coincides with the 210 basis point gross margin compression identified in income statement analysis, suggesting the cash flow gains may be partially reversible if capex catch-up spending materializes or if working capital efficiency reverts. The Q3 2026 EPS miss of $1.51 vs. $1.95 estimates, paired with maintained full-year guidance, implies management expects cash flow resilience to offset earnings pressure — a claim that warrants scrutiny given the Ball acquisition's unproven integration track record.
