The following unaudited pro forma condensed consolidated financial statements for NewMarket Corporation have been prepared to reflect the sale by Foundry Park I, LLC (Foundry Park) of certain real property in July 2013, as disclosed in Item 2.01 of this Form 8-K. The results of operation and financial position of Foundry Park, which comprised our real estate development segment, have been included in certain of our prior filings with the Securities and Exchange Commission (SEC).

The unaudited pro forma consolidated statements of income, which have been prepared for the three months ended March 31, 2013 and 2012 and for the years ended December 31, 2012, 2011, and 2010, give effect to the sale as if it had occurred at the beginning of each of the periods presented. The unaudited pro forma consolidated balance sheet has been prepared as of March 31, 2013 and gives effect to the sale as if it had occurred on that date. We prepared the unaudited pro forma adjustments based on the terms of the sale transaction and the financial position and results of operations of the real estate development segment for the periods presented.

The unaudited pro forma condensed consolidated financial statements are not necessarily indicative of actual or future financial position or results of operation that would have occurred or will occur as a result of the sale. These pro forma consolidated financial statements are based upon, and should be read in conjunction with, the historical consolidated financial statements of NewMarket Corporation, including the related notes to the financial statements.

Notes:

a. To record cash proceeds from the sale of certain real property (the sale) owned by Foundry Park I (Foundry Park), net of legal fees, broker’s commissions, and other closing costs totaling $1.0 million. Pursuant to the terms of the Purchase and Sale Agreement, $2.5 million of the cash proceeds will be held in escrow for 12 months from the closing date and are reflected in “Prepaid expenses and other current assets.”

b. To eliminate the net book value of the property, plant, and equipment, as well as to eliminate other assets and liabilities of Foundry Park.

c. To record estimated taxes payable on the gain on the sale. The effective tax rate on the gain on the sale differs from the statutory tax rate due to differences in the book basis and tax basis of certain assets and liabilities of Foundry Park.

d. To reclassify into earnings the accumulated unrealized loss, net of tax, related to the construction loan interest rate swap and mortgage loan interest rate swap. Refer to Note 16 of the Notes to Consolidated Financial Statements included in NewMarket Corporation’s 2012 Form 10-K.

e. To record the estimated gain on the sale as if the sale had occurred on March 31, 2013.

f. To eliminate the historical revenue and expenses for Foundry Park, as if the sale had occurred at the beginning of each of the periods presented.
