Rhea AI DGX FY2025 2026-10-03

Quest's 2025 rebound converted revenue growth into cash while leverage eased, but short-term financial flexibility remained thin relative to its operating scale.

Free cash flow margin expanded to 12.3% in FY2025 from 9.2% a year earlier, while net margin moved only to 9.0% from 8.8%. That divergence indicates cash conversion improved more than reported profitability, so the recovery was not simply an accounting-margin effect; more operating cash remained after reinvestment.

Revenue reached $11.0B in FY2025 while operating margin improved, showing incremental volume came with modest cost absorption rather than margin-free expansion. Free cash flow exceeded capital expenditures by 2.6x, indicating the business funded reinvestment internally while retaining cash for other uses instead of consuming all operating cash in maintenance investment.

Debt-to-equity fell to 0.7x from 0.8x, indicating 2025 growth did not require the same relative reliance on debt. Yet current ratio was 1.0x versus 1.6x in FY2021, so short-term assets only slightly exceeded obligations despite the broader deleveraging and leaving a limited working-capital cushion.
