18. 18 Recent Developments Wal-Mart Threat In June 07, Wal-Mart announced a $4 prescription program The effect didn’t last for long time (less than 6 weeks). This is not a threat because: The drugs covered by this program are not widely demanded by patients. For Walgreens prescription drug represents 65% of sales, of which 94.8% Third party sales. Third party : 1-Medicare : senior above 65 years 2-Medicaid : low income people 3-Private insurance Wal-Mart targets those who are not covered by any insurance and that represents 5% of the USA population.

19. 19 Recent Developments Cont. On Oct 1 st 2007, Walgreen announced a decline in Q4 earnings by 3.8%. Although the annual data showed an increase in earnings by 16.6%, sales increased by 13.3%. Walgreen lost 15% ($7.04) on that day. Walgreen is held by many institutional investors, so when Walgreen missed their expectations, shares sold off abruptly

20. 20 Recent Developments Cont. The management attributed this decline : Lower generic drug reimbursement Higher SGA, higher salary, store expenses, higher advertising cost and some administrative costs related to acquisitions The absence of new blockbuster generic drugs to enter the market during Q4. The expansion in third party selling (Medicare program) that has lower margins.

More generics start to appear, insurers force drug makers to lower the price, insurers pay lower reimbursements. Even when sales of Simvastatin (generic Zocor) tripled, yet gross profit was flat. At same time SGA costs increased by 15%, extra was needed staff to fill the increase in the size of business
