Acuity Brands, Inc. (AYI) Cash Flow Statement

The elevated OCF/NI ratio appears driven in part by rising depreciation and amortization — which climbed from $22.9M in Q3 2024 to $46.4M in Q4 2025 following the $1.2B acquisition completed in mid-2025 — suggesting that reported net income may understate the cash-generation potential of the asset base. However, the ratio has been highly volatile, ranging from 0.77 in Q2 2025 to 2.11 in Q3 2025, indicating that a meaningful portion of the conversion advantage is tied to working capital timing rather than a stable structural driver. Investors should monitor whether the more recent OCF/NI readings above 1.75 in Q3–Q4 2026 prove durable or reflect seasonal collection patterns.

The Q2 2025 FCF margin of 4.9% coincides with the $1.2B acquisition quarter, where working capital outflows of $60.0M combined with elevated acquisition spending compressed cash generation severely. Since then, FCF margins have recovered to 22.8%–23.0% in the most recent two quarters, a level that appears elevated relative to the company's historical 11.9%–16.3% range. Given that the income statement analysis already signals revenue deceleration to 2.9% in Q4 2026, the sustainability of these elevated FCF margins warrants further investigation as the working capital tailwind fades.

The most recent quarter shows a $120.6M working capital outflow, which appears to suggest either inventory build or receivable timing pressures that coincided with the revenue deceleration noted in the income statement analysis. Conversely, the $95.0M working capital release in Q3 2026 may have flattered operating cash flow, meaning the apparent improvement in OCF/NI ratios could reverse once collections normalize. Given the company's project-based revenue model tied to non-residential construction cycles, investors should monitor whether this volatility reflects genuine demand shifts or distributor destocking dynamics that could distort near-term cash visibility.

The aggressive buyback pace appears funded by the company's strong operating cash generation rather than incremental borrowing, given the reported low debt-to-equity ratio of 0.37%, suggesting the capital structure remains conservative despite elevated deployment. Dividends remain modest at approximately $5–6M per quarter, indicating management prioritizes share count reduction over income-oriented shareholder returns. However, the $1.2B acquisition completed in mid-2025 suggests capital deployment is being split between buybacks and inorganic growth, raising the question of whether ISG integration will require additional cash investment that could constrain repurchase capacity.
