Updates to Website Frequently Asked Questions
- Q.
- The company expects to obtain $125 million in synergies within twelve months of closing the transaction. Can you be more specific in terms of where you
expect to achieve the $125 million in synergies?
- We
anticipate that approximately 75% of the $125 million in synergies will be related to purchasing efficiencies. These synergies were calculated by
an independent third party's review of existing purchasing relationships and practices of both companies. In addition, the $125 million in synergies includes eliminating duplicate public
company expenses (e.g., duplicate executive expenses, insurance policies, securities filings, stock exchange expenses, etc.).
- The
$125 million in synergies does not include any revenue enhancements derived from cross selling opportunities or higher profitability due to
increased mail order penetration. These enhancements, as well as further purchasing synergies and efficiencies, are anticipated to begin occurring subsequent to year one.
- Q.
- When will you know what your net new business wins are for 2004?
- There
is still a robust pipeline of potential new clients that haven't made final decisions on where to award their business for 2004. We anticipate that
most of those decisions will be made later this year. As usual, we are planning to update shareholders on net new business along with Caremark's third quarter earnings release.
- Similarly,
AdvancePCS also will update shareholders on new business prospects during its September quarter earnings call.
- Q.
- Was this transaction necessary to maintain Caremark's growth trendsparticularly net new business levels?
- Absolutely
not. As you are aware, both companies have been performing very well. Caremark has enjoyed significant net new business wins of between
$400 million and $800 million over the course of the last four yearswith the exception of last year's record new business total of $1.3 billion. We believe that this
demonstrates plan sponsors' beliefs that Caremark adds value in helping them control their drug spending.
- Potential
new business wins had nothing to do with our decision to combine Caremark and Advance PCS.
- This
transaction is expected to create enhanced growth opportunities stemming from a balanced business model, improved financial flexibility and exceptional
cash flow.
- Q.
- What do customers think of the transaction?
- Overall,
the customer base has responded quite positively. We anticipate being able to give them expanded service offerings and choices after the
transaction closes, including a broader set of specialty and disease management programs.
