Strategic Rationale & Synergies

1. Fulfillment Network & Density Scale:

   • By combining order flows, DoorDash aims to boost courier and shopper density in the last-mile network, driving down per-delivery costs and expanding delivery speed.
   • Expansion of DashMart Fulfillment Services to Instacart retail partners allows grocers to manage inventory and improve order fulfillment accuracy (closing the accuracy gap from low 90s in third-party stores toward near-perfect rates in DashMarts).

2. Cross-Platform Growth Levers:

   • Cross-listing: Integration will enable DoorDash restaurant selection to appear on Instacart and cross-list non-overlapping retail categories across both platforms.
   • Advertising / CPG: Increased audience reach enables higher advertiser spend and higher return on ad spend (ROAS) across CPG brands.
   • First-Party Retail Software: Instacart’s white-label e-commerce storefront infrastructure will be cross-sold across DoorDash’s grocery and convenience merchant base.

3. Financial Synergy Profile:

   • Year 1: DoorDash plans to reinvest 100% of initial synergy capture into customer experience, merchant tools, and pricing.
   • Year 2: Phased operational efficiency capture.
   • Year 3: Projected $500 million or more in annual incremental synergies net of ongoing investments.

Tech Stack & Integration Roadmap

• DoorDash's existing replatforming project to unify its core infrastructure (and previous acquisitions Wolt and Deliveroo) is on schedule for completion in the first half of 2027.
• The new modular infrastructure was intentionally designed to support future platform additions, lowering the marginal technical friction of onboarding Instacart.
