Lufkin Industries Reports 22.0% Growth in Fourth-Quarter Earnings per Diluted Share to $0.61

LUFKIN, Texas, Feb. 10 --

Lufkin Industries, Inc. (Nasdaq: LUFK) today announced results for the fourth quarter and twelve months ended December 31, 2004. Sales for the fourth quarter increased 43.8% to $107.4 million from $74.7 million for the fourth quarter of 2003. Net earnings rose 28.5% to $4.3 million for the fourth quarter of 2004 from $3.4 million for the fourth quarter last year. Net earnings per diluted share were $0.61 for the fourth quarter of 2004, an increase of 22.0% from $0.50 for the fourth quarter of 2003.

Sales for 2004 increased 35.6% to $356.3 million from $262.3 million for 2003. Net earnings were $14.4 million for 2004 up 48.1% from $9.7 million for 2003. Net earnings per diluted share grew 41.8% for 2004 to $2.07 from $1.46 for 2003.

Douglas V. Smith, president and chief executive officer of Lufkin, remarked, "Lufkin's substantial profitable growth for the fourth quarter of 2004 capped a year of strong performance by the Company and positioned us well to achieve further growth in 2005. As we have experienced throughout 2004, our oil field division led our growth for the fourth quarter with a 49.6% increase in sales from the fourth quarter of 2003 and a 13.3% increase from the third quarter of 2004. This growth continued to be driven by strong demand in the U.S. and Canada for new pumping units, which also contributed to the significant growth of our foundry operations, as well as in our services and automation businesses. In addition, in the fourth quarter international demand for new pumping units increased.

"We were also pleased with the performance of our power transmission division for the fourth quarter, which produced 26.3% comparable-quarter growth in sales and 24.3% sequential quarter growth. These increases reflect an improved environment throughout the business, although sales continued to reflect greater activity in industrial markets for lower speed gear products and in our gear repair business than in high-speed gear markets. Our trailer division sales increased 50.7% for the latest quarter over the fourth quarter of 2003, consistent with the stronger environment demonstrated for the last two quarters versus the prior year. Fourth-quarter trailer sales were 3.8% lower than the third quarter of 2004, primarily in response to higher pricing that more fully reflected the significant increases in raw materials during 2004.

"We complemented our strong comparable-quarter sales performance by achieving 86% growth in our backlog to $113.2 million at the end of 2004 from $60.9 million at the end of 2003. Illustrating the strong demand for new pumping units discussed earlier, our $61.6 million backlog for the oil field division increased 147.1% from the end of 2003 and 30.1% from the end of the third quarter of 2004. The power transmission division also produced a substantial increase in its backlog during 2004, to $40.1 million, which was up 61.4% from the end of 2003 and 4.5% from the end of the third quarter of 2004. Again reflecting the higher pricing environment that affected sequential-quarter trailer sales, the trailer division's backlog increased 3.9% to $11.5 million at the end of 2004 from year-end 2003 and decreased 22.8% from the end of the third quarter of 2004."

Based on Lufkin's fourth-quarter and full-year 2004 financial results and its backlog at the end of 2004, the Company today established its guidance for earnings per diluted share for 2005 in a range of $3.00 to $3.50. The Company also established its guidance for earnings per diluted share for the first quarter of 2005 in a range of $0.65 to $0.85, compared with $0.25 for the first quarter of 2004.

Mr. Smith added, "In addition to the much improved operating environment created by increases in oil prices and an expanding economy, we expect our 2005 results to benefit from a more stable pricing environment for steel and other raw materials. As evidenced by the pressure on our gross profit margin during the past year, we have been limited in our ability to raise product prices to match rapid increases in raw material costs, as we experienced in 2004. We believe the stabilization of raw material costs will enhance our ability to price our products to reflect earlier cost increases more fully, contributing to a recovery in our profit margins. Moreover, we believe our suppliers are better positioned to eliminate some of the temporary interruptions of supplies that negatively impacted 2004 production."
