This case tests core financial analysis skills including incremental revenue calculations, cannibalization effects, and breakeven analysis. The key insight is recognizing that opening a new store causes a 10% decline in the original location's sales, which candidates must account for when calculating true incremental profit.

Fred and George Weasley operate a magic joke shop, Weasleys’ Wizarding Warehouse (Weasleys’). They currently have a single storefront located in the Diagon Alley shopping district. This store primarily sells magic products used for pranks to young students that attend Hogwarts School of Witchcraft and Wizardry. It has come to their attention that another store location has become available for sale in Hogsmeade, a small village near Hogwarts. The Weasley brothers are interested in expanding the business and are curious if opening a second location in Hogsmeade makes sense.

Clarifying Information

  1. Are there current competitors in the market? Zonko’s joke shop is another magical store currently located in Hogsmeade. Fred and George aren’t too worried, however. They believe they will be able to capture up to 30% of the existing market in Hogsmeade.
  2. What are the Weasley’s financial goals? Looking to breakeven on the investment within 4 years of expansion.
  3. What type of products to they sell? They have three best-selling products: fake wands, smart-answer quills, and love potions.

Weasleys’ Wizarding Warehouse, a magical joke shop with one location in Diagon Alley, is evaluating whether to expand to a second location in Hogsmeade. The case requires analyzing incremental revenue (accounting for 10% sales cannibalization), calculating profitability across both locations, and determining if the expansion meets the 4-year breakeven financial goal.

Key Insights:

  1. Cannibalization analysis is critical - the Diagon Alley store experiences exactly 10% sales decline across all products when the new store opens
  2. Incremental revenue must account for both new sales ($120K) minus the loss from the existing store to determine true net benefit
  3. The expansion increases total annual profit from $102K to $156K ($54K improvement) while meeting the 4-year breakeven requirement
  4. Market entry strategy must consider competition (Zonko’s) and realistic market capture assumptions (30% of existing market)
