GPC Employee FAQ

What was announced?

Genuine Parts Company announced a definitive agreement under which the S.P. Richards business will be spun off into a standalone company and then merged with Essendant.

Once the transaction has been completed, Genuine Parts Company shareholders will continue to own their existing shares in Genuine Parts Company and will also own approximately 51% of the new, combined company. Essendant shareholders will own approximately 49% of the new, combined company.

Together, S.P. Richards and Essendant will form a stronger, more competitive company with greater scale and service capabilities and an enhanced ability to support our customers.

Who is Essendant?

Essendant is a leading national distributor of business products headquartered in Deerfield, IL.

Essendant provides its customers with access to over 170,000 items, including janitorial and breakroom supplies, technology products, traditional office products, industrial supplies, cut sheet paper products, automotive products and office furniture.

Like S.P. Richards, Essendant serves a diverse group of customers, including independent resellers, national resellers and e-commerce businesses.

Essendant shares our passion for serving customers and has a long history of delivering business products to growing businesses, a record we look forward to continuing together as an even stronger combined organization.

When will the transaction be completed?

We expect this transaction to close before the end of 2018, subject to customary closing conditions and regulatory approvals.

Until then, S.P. Richards will remain a part of Genuine Parts Company and S.P. Richards and Essendant will continue to operate independently.

In short, it is business as usual for all of us and it is important that you remain focused on your day-to-day responsibilities and delivering reliable service to our customers.

What is required in order to close the transaction?

The transaction is structured in a form called a Reverse Morris Trust, under which Genuine Parts Company will go through a process to separate the S.P. Richards business prior to combining it with Essendant.

As part of this process, we will need to obtain certain regulatory approvals and the approval of Essendant shareholders. This transaction does not require the approval of Genuine Parts Company’s shareholders.

What happens to the shares of Genuine Parts Company stock that I own?

Employees who own Genuine Parts Company shares when the transaction closes will continue to own those Genuine Parts Company shares. The shares you currently have invested in Genuine Parts Company stay the same.

Upon completing the combination of S.P. Richards and Essendant, employees who own Genuine Parts Company stock will receive shares in the new combined company. The amount of shares will depend on the number of Genuine Parts Company shares an individual employee owns at the time of the transaction closing.

Your new shares will be automatically deposited into the accounts that currently hold your Genuine Parts Company shares.

GPC Employee FAQ

Genuine Parts Company remains committed to its dividend policy and the dividend on your Genuine Parts Company shares will remain the same.

It is still early in the process and the valuation of the combined business will be clearer as we moved toward the close of the transaction. That said, we are confident that this transaction will provide shareholders significant value through both the future upside of the new company as well as Genuine Parts Company’s focus on its core businesses.

Explain the one-time dividend paid to Genuine Parts Company. Does that mean I get a dividend if I have Genuine Parts Company shares?

The dividend paid to Genuine Parts Company represents a portion of the total value to be paid for S.P. Richards.

Genuine Parts Company shareholders are not getting paid the dividend directly.

Genuine Parts Company’s Board and management will evaluate the use of the dividend based our disciplined capital allocation strategy, which is focused on our dividend, reinvestment in our businesses, share repurchase and strategic acquisitions. These are ongoing priorities for our cash and are intended to drive enhanced value for our shareholders.

What will happen to the S.P. Richards name? What about S.P. Richards’ brands?

The new company will be called Essendant.

Both businesses enjoy solid branded and private-label products businesses with strong brand equity among our respective customer bases. We expect the combined company to continue leveraging these strengths across a broad set of categories.

In the coming weeks, S.P. Richards and Essendant will form an integration planning team consisting of leaders from both organizations to determine how best to bring our two businesses together. Decisions regarding our go-forward branding strategy, including our private-label products businesses, will be determined and shared as we move through the process.

What should I say if asked about this transaction?

As is common with announcements like these, today’s news may lead to increased interest in our company, and it is important that we speak with one voice. Please refer any external or media inquiries to Sid Jones, SVP of Investor Relations, at 678-934-5628 or Sid_jones@genpt.com.
