Chris Saridakis Shares His Thoughts on Planned Acquisition

After the eBay acquisition of GSI Commerce closes, Chris Saridakis will lead the GSI business unit. Currently, Chris is CEO of GSI’s Global Marketing Services division. He joined GSI in May 2010 from Gannett Co., Inc., a leading news and information service, where he served as senior vice president and chief digital officer and head of Gannett Marketing Services. You can read more about Chris’s background on gsicommerce.com. With this in mind, we wanted to share Chris’s viewpoints on GSI and the planned acquisition:

Q: What are GSI’s business priorities for the second half of 2011?

Chris: We need to continue to develop and deliver leading products and services in order to drive top-line growth for clients and GSI. It is as simple as that: deliver great products and services to drive top line growth for our clients and GSI.

Q: What should employees focus on until the acquisition is completed?

Chris: While there are many integration planning activities underway, both GSI and eBay are required to operate independently and actual integration will not begin until the deal is closed. Until then, it is important to understand that it is business as usual for both GSI and eBay.

Q: How will peak activities be affected by the acquisition?

Chris: The acquisition should have no impact on peak activities. I want everyone to focus on making peak activities run smoothly for our clients and their consumers, just like we always do.

Q: How will the acquisition impact the launch of v11?

Chris: It is my understanding that eBay has great confidence in the v11 technology and product direction and recognizes that the v11 program is critical to the success of GSI and central to the value GSI will deliver for eBay. John Donahoe and his leadership team expect that, if the acquisition is completed, eBay will fully support the successful delivery and deployment of v11. This starts with deploying v11 to our existing clients and then aggressively taking the v11 products to market to grow GSI and eBay’s business.

Q: What changes will clients notice after the acquisition?

Chris: By becoming part of eBay, GSI believes that it will be better positioned to support clients as they compete in this ever-changing environment. We believe that by combining GSI’s leading e-commerce and interactive marketing services with eBay’s global online marketplaces and payments platforms expertise, together with eBay’s mobile commerce leadership and focus on innovation, we will be positioning GSI to be the strategic commerce partner of choice for retailers of all sizes.

Q: What is your vision for GSI?

Chris: I believe that eBay will help us become a great company faster than we would have done on our own. I anticipate that eBay will be able to provide GSI with greater access to the resources that GSI needs to execute on our strategy and expand our reach globally.

Q: What aspects of the acquisition are you most excited about? Which aspects keep you up at night?

Chris: I’m excited to have the opportunity to take GSI to the next level and to work with eBay, which I believe will help us get there faster. I worry that employees will become distracted during the integration process. I can’t emphasize enough how important it is to focus on delivering great products and services and continuing to help our clients grow their businesses.

Q: How many acquisitions have you experienced in your career? What are some of things you’ve learned along the way?

Chris: I’ve been a part of or led more than a dozen acquisitions and similar activities during my career. I think it’s important to remain focused on the things that matter most — delivering results.

Q: What will GSI look like this time next year? In five years?

Chris: I expect that GSI will continue with its strategy of operating highly competitive, market-leading businesses. We will constantly evaluate our organization and offerings to ensure that we have the right structures in place to best serve our clients and the market. With more than 50% of its revenue coming from outside of the U.S., I believe that eBay is the perfect partner for GSI and its clients as we embark on our global expansion. eBay and GSI believe that the acquisition will enable eBay to leverage its global footprint to accelerate GSI’s international market expansion. I have every intention of making GSI a very large, highly successful global business.

Q: What will be the relationship between NRG and GSI after the close?

Chris: GSI will continue to provide technology, call center and marketing services for RueLaLa, ShopRunner and Fanatics and its clients after the acquisition, and subsequent divestiture, are completed. We expect a long and highly valuable partnership with NRG, similar to all of our important clients.

Q: What are key similarities and differences you see between GSI and eBay culture and/or approach to business?

Chris: Both companies are passionate about winning. With their complementary capabilities, I believe that GSI and eBay together will offer an unmatched suite of global commerce services. This powerful platform will drive shopping innovation and new ways for retailers and brands to engage customers and help people shop anytime, anywhere and on any device.

Integration Planning Update

In the days following the announcement of eBay’s planned acquisition of GSI, senior leaders from both companies gathered in King of Prussia, Pennsylvania to begin planning activities. The graphic represents the planning tracks. Employees from both companies co-lead each track and the workstreams within the tracks.

Communications

Both GSI and eBay are committed to keeping GSI employees up to date with the latest information before and after the closing of the acquisition. We’ll leverage this employee newsletter, along with other types of communications, to inform GSI employees of any relevant news and key pieces of information that we believe are critical to communicate as integration decisions are made. Below is the timeline of expected communications that will support integration activities. The items in blue are expected to happen before the closing of the acquisition. The items in green are expected to occur after the acquisition closes. As can be expected, the timeline is subject to change without notice, as we continue with the integration process.

Employee FAQs

Each newsletter will feature a section on the most frequently asked questions (FAQs) that are on the minds of GSI employees. Please feel free to submit any questions to ebayquestions@gsicommerce.com.

Has the expected timing of the completion of the acquisition with eBay changed?

There have been no changes at this point. GSI has announced that it expects the transaction to close as early as the end of the second quarter of 2011.

As an employee, what should I be doing to prepare for joining eBay?

For most employees, there will be very little changing on Day 1, the first day of joint operations. You should remain focused on your daily responsibilities and the clients we serve.

However, there are a number of forms that GSI employees will need to complete in advance of Day 1, including an I-9 (Employment Eligibility Verification) form and eBay-specific policy and agreement documents that an employee would typically sign when joining a new company. You will need to show identification documentation for the I-9 form, so be sure to have your chosen documents with you when you turn in your paperwork (see http://www.uscis.gov/files/form/i-9.pdf) You will receive detailed instructions and schedules regarding these requirements in the days and weeks ahead.

Where and when are King of Prussia-based NRG employees moving? What about other NRG employees?

Since GSI and NRG will be separate companies, we do expect to have some changes over time for employees who will join NRG. In the coming months, NRG employees who are currently based in King of Prussia will relocate to nearby office space in Conshohocken, Pennsylvania. Real estate decisions for other NRG locations will be evaluated on a case-by-case basis and we understand that NRG will notify affected employees as appropriate.

When will we learn more about the employee benefits that will be available to employees who become part of eBay?

We anticipate that for now, most benefits will remain the same. Over time, we will evaluate our benefits programs and align them with eBay’s benefits programs as appropriate. We will communicate more information as decisions impacting your benefits are made.

When will we learn more about GSI leadership appointments?

GSI has already announced that Chris Saridakis will be leading the GSI business unit within eBay upon the close of the transaction. We anticipate that the senior leaders reporting directly to Chris will be announced as soon as possible after GSI becomes a part of eBay.

I heard that there was a leadership meeting on May 31. What was discussed?

There was a meeting for Directors and VPs on May 31 that included an integration planning update, an overview on GSI’s role in eBay’s strategy and future, and an update on plans for NRG. Leaders will be meeting with their teams to share these updates.

If you have additional questions, please contact ebayquestions@gsicommerce.com.
