NewMarket Corporation Reports Improved First Quarter 2006 Results 

Richmond, VA, April 25, 2006 – NewMarket Corporation (NYSE:NEU) President and Chief Executive Officer, Thomas E. Gottwald, released the following earnings report for the first quarter 2006.

Net income for the first quarter 2006 was $13.8 million or 79 cents per share, a significant improvement compared to first quarter 2005 net income of $4.8 million or 28 cents per share.  The results include improvement in the petroleum additives segment while TEL results continue to decline.

Petroleum additives sales for the first quarter of this year were $299.5 million, an increase of $62.4 million or 26 percent over first quarter sales last year of $237.1 million.  Shipment volumes improved approximately 10% in this quarterly comparison.  Petroleum additives operating profit for the first quarter of this year reached $25.7 million, an increase of $16.6 million over operating profit for the first quarter 2005 of $9.1 million.  The higher profit generally reflects improvement in all of our major product lines.   While the key component in the profit improvement was volume, some progress was made to restore margins both by improved pricing and the introduction of more cost effective products.  

Tetraethyl lead (TEL) operating profit for the first quarter of this year was $0.2 million, compared to $4.3 million for the first quarter of 2005.  The lower profit in the first quarter of this year reflects much lower shipments.  Income from the TEL segment may vary greatly from quarter to quarter with shipments and earnings in 2006 expected to be significantly lower than last year. 

Our improved earnings and strong financial position enabled our Board of Directors to declare a quarterly dividend of 12.5 cents per share on the common stock of the Corporation, which was paid on April 3, 2006 to NewMarket shareholders of record at the close of business on March 16, 2006.  While our Board of Directors has authorized a stock buy back program, we did not repurchase any of our common stock during the first quarter of this year. 

The improvement in earnings in the first quarter of this year reflects the continuing success of the entire NewMarket team in growing our petroleum additive product lines. The entire team is focused on our efforts to improve profitability in this highly competitive marketplace. Our raw material costs continue to rise, driven by the most recent increases in crude oil prices and by a tight supply and demand balance for certain purchased chemicals.  We constantly monitor the adverse impact of raw material increases and will be in the marketplace to recover those costs as appropriate.  We remain active in our efforts to review acquisition opportunities, but will be patient in the ultimate outcome.
