Ecovyst Inc. (ECVT) Cash Flow Statement

The OCF/NI ratio has been consistently above 4 in profitable quarters, reaching 4.35 in 2026Q2, which suggests that reported earnings understate the cash-generating ability of the business. The gap is largely attributable to non-cash charges like D&A and impairments, which are added back to operating cash flow. This indicates that the company's core operations are generating healthy cash flows, even when net income is depressed by non-operating items.

The FCF trajectory is highly volatile, with margins ranging from -9.8% to 26.0% over the past ten quarters. This volatility appears to be driven by timing of capex and working capital changes, rather than a fundamental deterioration. The 2026Q2 FCF of $3.7M is modest, but the company's ability to generate positive FCF in most quarters, despite heavy capex, suggests a stable underlying cash flow profile. Investors should monitor whether the recent acquisition of Waggaman will sustainably boost FCF margins.

The capital expenditure ratio is consistently high, ranging from 1.0% to 16.9% of revenue, which is typical for a specialty chemicals company with heavy fixed assets. The elevated capex in 2026Q2 ($30.7M) likely includes growth investments related to the Waggaman acquisition, but a substantial portion appears to be maintenance capex given the high D&A levels. This suggests that the company must continually reinvest to sustain its asset base, which could limit FCF growth unless revenue expands.

The working capital changes are highly erratic, with both positive and negative swings exceeding $30M in some quarters. This suggests that the company's cash conversion cycle is sensitive to the timing of receivables and payables, possibly due to the lumpy nature of catalyst sales. The positive working capital change in 2026Q2 ($242K) is minimal, indicating a neutral impact, but the prior quarter's negative $10.0M suggests ongoing volatility. Investors should monitor whether management can smooth these swings through better working capital management.

The company has not paid dividends in any of the ten quarters, but has engaged in sporadic share repurchases, with the largest being $36.3M in 2026Q1. This suggests that management views buybacks as a more flexible way to return capital, possibly due to the need to preserve cash for debt reduction or acquisitions. The $568.3M acquisition in 2025Q4 (likely Waggaman) indicates a strategic focus on growth through M&A, which may limit future buyback capacity. Investors should assess whether these deployments are generating adequate returns.

The cumulative gap between operating cash flow and net income is substantial, with OCF totaling $341.3M versus a net loss of $65.6M. This divergence is primarily due to non-cash charges such as D&A and impairments, which are added back to OCF. This suggests that the company's earnings quality is low, but its cash generation is robust, which may be a positive signal for valuation. However, the negative cumulative net income raises concerns about long-term profitability, and investors should monitor whether the gap narrows as impairments subside.
