NewMarket Corporation Reports First Quarter 2005 Results 
Richmond, VA, May 4, 2005 – NewMarket Corporation (NYSE:NEU) filed its first quarter 2005 Form 10-Q with the Securities and Exchange Commission today.  The following summary and financial statement are from that filing.


First quarter 2005 net income was $4.8 million, or $.28 per share, compared to net income of $5.8 million, or $.35 per share, for the first quarter last year.  The results reflect lower earnings in both the petroleum additives and TEL segments. 

Petroleum additives net sales for the first quarter 2005 improved 10 percent compared to the same period last year.  However, the continuing increases in raw material costs have reduced our margins.   TEL operating profit was lower in first quarter 2005 compared to the same period last year primarily reflecting lower shipments partially offset by an increase in selling price.  Net income for first quarter 2005 benefited from lower corporate and administrative cost, as well as lower interest and financing cost.
