A financial covenant is a contractual obligation included in a credit agreement that requires the borrower to maintain certain financial ratios within agreed thresholds throughout the life of the loan. Covenants are the primary credit protection mechanism for lenders in leveraged transactions and are negotiated at the time of signing — making their initial calibration critically important for the borrower's operational flexibility throughout the holding period.

‍

The most common financial covenants in Franco-Swiss LBOs include: the leverage ratio (Net debt / EBITDA, typically capped at 4.5–5.5x), the DSCR (minimum 1.20–1.25x), the Interest Coverage Ratio (EBITDA / Net interest, minimum 2.0–3.0x), and the Capex limitation (maximum annual capital expenditure). Covenants are tested quarterly on a trailing 12-month basis.

‍

When a covenant is breached, the borrower must immediately notify the lender and request a formal waiver. Waiver negotiations typically result in: a margin step-up (increase in interest rate), additional reporting obligations, restrictions on dividend payments or additional acquisitions, and sometimes the appointment of an independent financial advisor at the borrower's cost. Repeated covenant breaches can trigger cross-default provisions, accelerating the entire debt.

‍

Covenant headroom — the buffer between the actual financial ratio and the covenant threshold — should be at least 20–30% to absorb normal operational volatility. Securing adequate headroom in the initial negotiation is as important as the absolute level of the covenant threshold.

‍

Example: an LBO financing agreement includes a leverage covenant of maximum 4.5x EBITDA tested quarterly. The company's actual leverage is 3.8x — a headroom of 15.5%. When EBITDA falls 15% due to a client loss, leverage rises to 4.47x — dangerously close to the threshold, requiring proactive lender communication and potentially a waiver to avoid a technical default.
