We have successfully diversified our customer base, but we rely heavily on a single primary supplier for our main product line. How do we mitigate this vendor concentration risk on our exit runway so a buyer does not penalize our valuation during due diligence?

Just as customer concentration worries buyers, supplier concentration is a major red flag that can derail a transaction or lead to severe valuation haircuts. If your primary supplier goes out of business, changes their terms, or cuts you off, your operational engine stalls. To address this risk on your runway, you must establish a dual-sourcing strategy. Begin by identifying alternative suppliers who can deliver the same quality and volume of materials or services. Even if your primary supplier offers the best pricing, you need to route a portion of your business to a secondary supplier to keep the relationship active and verified. Next, secure formal, transferable contracts with your key vendors. A buyer wants to know that your pricing, lead times, and supply lines are legally protected and will remain intact post-sale. Document your supply-chain redundancy plans clearly in your operational manuals. When you can show a prospective buyer that you have qualified backup suppliers ready to scale on short notice, you neutralize their concerns about supply chain vulnerability, protecting your valuation multiple and ensuring a smoother due diligence process.
