Impact of rising interest rates on M&A financing structures

Rising interest rates reshape how mergers and acquisitions (M&A) are financed. Borrowing costs increase, lenders tighten underwriting standards, and both buyers and sellers adjust deal structures to maintain transaction feasibility. Private equity sponsors, corporate acquirers, and strategic investors must adapt their capital stacks, pricing expectations, and risk assessments as the cost of debt rises and access to credit becomes more selective.

How higher interest rates influence M&A deal economics.

As rates climb, the cost of debt directly affects a transaction’s financial feasibility and valuation:

• Increased interest expenses reduce pro forma earnings and cash flow coverage ratios.

• Higher required equity contributions place greater demands on investor capital.

• Valuation multiples contract as leveraged buyers adjust for reduced returns on invested equity.

• Lenders impose stricter covenants and demand more conservative leverage levels.

The effect is especially pronounced in sectors that rely heavily on debt-funded acquisitions.

Shifts in financing structures amid tighter credit conditions.

Companies and sponsors adopt new approaches to secure funding and mitigate risks:

Adjustment	Description	Result
More equity, less debt	Sponsors fund a larger share of the purchase price with equity	Lower leverage, reduced risk
Shorter maturities	Lenders favor shorter-term loans to manage rate uncertainty	Increased refinancing pressure
Floating-rate instruments	Borrowers use loans linked to variable rates	Greater exposure to rate volatility
Alternative lenders	Sponsors turn to private credit and direct lenders	Broader but more expensive capital sources
Seller financing	Sellers accept deferred payments or vendor loans	Risk shifts to sellers, delays liquidity

Hybrid structures balance cash flow predictability with funding flexibility.

Impact on private equity and leveraged buyouts.

Private equity firms experience particular pressure as higher rates narrow the spread between cost of debt and target company earnings:

• Entry multiples decrease as leveraged returns diminish.

• Debt service constraints push sponsors to pursue less aggressive capital structures.

• Preferred equity and mezzanine debt take on greater roles in capital stacks.

• Add-on acquisitions and bolt-ons remain attractive as platforms de-lever and pursue organic growth.

Sponsors with strong relationships across financing markets retain greater agility in structuring competitive bids.

Corporate buyers face new valuation and funding realities.

Strategic acquirers also adjust their approach to dealmaking in higher-rate environments:

• Outright cash deals become more appealing as debt-financed transactions lose economic appeal.

• Treasury teams lock in fixed-rate debt ahead of anticipated hikes.

• More frequent use of earn-outs, contingent payments, and creative structuring to bridge valuation gaps.

• Increased focus on synergy realization and operational improvements to offset financing headwinds.

Disciplined capital allocation gains importance as financing costs challenge return thresholds.

Valuation and pricing considerations as rates climb.

As the cost of capital increases, dealmakers adjust valuation models and negotiation tactics:

• Discount rates used in discounted cash flow (DCF) analyses rise, lowering present values.

• Buyers favor targets with strong cash flow generation and low capital intensity.

• Sellers face greater scrutiny on projections, risk factors, and contingency planning.

• Transaction timelines may lengthen as parties secure financing or renegotiate terms.

Deals proceed when both parties share realistic expectations about cost, risk, and value creation.

Examples of dealmaking in higher-rate environments.

• Private equity sponsors reduce average leverage multiples in technology and healthcare platform acquisitions.

• Strategic buyers pursue smaller, cash-funded bolt-ons instead of large, fully-leveraged buyouts.

• Real estate M&A shifts toward joint ventures and partnerships to balance debt loads and equity requirements.

• Companies issue more convertible debt or hybrid securities as alternatives to pure leverage.

These adaptations reflect the shift in market dynamics and risk tolerance.

Higher interest rates demand flexible, resilient financing strategies in M&A.

Rising rates prompt sponsors, corporates, and lenders to refine capital structures, adjust pricing, and develop creative funding solutions. Focus turns to strong cash flow, conservative leverage, and deal terms that can weather ongoing rate volatility while preserving value for all transaction participants.
