RUNWAY EXTENSION OR VALUE EROSION? A DIFFERENCE-IN-DIFFERENCES STUDY OF PIK AMENDMENTS AND CAPITAL-STRUCTURE OUTCOMES IN U.S. SPONSOR-BACKED LBOS (2020–2025)

Abstract

This paper studies how Payment-in-Kind (PIK) amendments affect capital structure and near-term risk in U.S. sponsor-backed LBOs. Using a difference-in-differences design on a panel of transactions from 2020–2025, we find that, after a PIK amendment, leverage rises by ~+1.01x EBITDA and the 12-month default probability increases by ~0.9 percentage points—consistent with near-term cash relief but a larger claim as interest capitalizes. Outcomes are heterogeneous: when sponsors pair PIK with fresh equity and dated operating milestones, stabilization and refinancing are more common; unsupported PIKs frequently re-default within ~24 months. Practically, lenders should treat PIK as a bridge only when milestones and covenants discipline execution, and risk teams should flag clustered PIK usage as an early stress signal. The results clarify when PIK extends runway versus erodes value in distressed leveraged finance.
