GORMAN-RUPP REPORTS FOURTH QUARTER AND FULL-YEAR 2012 RESULTS

Mansfield, Ohio – February 8, 2013 – The Gorman-Rupp Company (NYSE MKT: GRC) reports financial results for the fourth quarter and twelve months ended December 31, 2012, highlighted by record sales during 2012 and the attainment of forty consecutive years of increased cash dividends paid to shareholders. Operating results for 2012 include Pumptron (Proprietary) Limited (“Pumptron”) and the American Turbine Pump companies (“American Turbine”) acquired in the third and fourth quarters of 2012, respectively.

Net sales for the twelve months ended December 31, 2012 increased 4.5% to a record $375.7 million compared to $359.5 million during the same period in 2011. Encouragingly, total international sales increased more than 15% to a record $136.5 million. Sales improved 6.0% in our larger water end markets and 4.9% in our non-water end markets. Major contributions to water market sales were international shipments of pumps for fire protection and an increase in agricultural market sales, partially offset by reduced construction market demand for pumps for natural gas drilling applications and from rental businesses. The increase in non-water market sales was primarily due to petroleum market shipments and international industrial market shipments. Sales of repair parts decreased modestly during 2012, as sales during 2011 were bolstered by pent-up demand.

Gross profit was $90.2 million in 2012, resulting in gross margin of 24.0% compared to 24.4% in 2011. The decline in gross margin was principally due to a less favorable product mix combined with increases in healthcare costs and depreciation expense. Operating income was $42.2 million resulting in operating margin of 11.2% compared to 12.0% in 2011. The decline in operating margin was impacted as well by non-recurring acquisition-related expenses. As noted in the Company’s third quarter 2012 Form 10-Q, a GAAP-required $2.9 million non-cash pension settlement charge was subsequently required to be recorded in the fourth quarter 2012; this was comparable to the $3.0 million non-cash pension settlement charge recorded in the fourth quarter 2011. Excluding these non-cash charges, gross margin was 24.5% and 25.0% and operating margin was 12.0% and 12.8% for 2012 and 2011, respectively.

Net income for 2012 was $28.2 million, our second highest net income, compared to a record $28.8 million in 2011. Earnings per share were $1.34 and $1.37 for the respective years. Excluding the decrease of $0.09 and $0.10 per share due to the non-cash pension settlement charges described above, earnings per share were $1.43 and $1.47 for 2012 and 2011, respectively.

Net sales during the fourth quarter 2012 were $88.7 million compared to a record $93.0 million during the same period in 2011, a decrease of 4.7%. Sales declined $1.4 million during the quarter in our larger water end markets and $2.0 million in our non-water end markets compared to the same period last year. The decrease in water market sales was primarily due to reduced construction market demand for pumps for natural gas drilling applications and for rental businesses, partially offset by an increase in agricultural market sales. The quarter’s decline in non-water market sales was primarily in the OEM market due to reduced shipments of fabricated products related to power generation equipment. Sales of repair parts decreased $1.0 million in the fourth quarter of 2012 compared to the elevated demand experienced during the fourth quarter 2011.

Gross profit was $18.9 million for the fourth quarter 2012 resulting in gross margin of 21.3%, comparable to 21.2% in the same period last year. Operating income was $5.4 million resulting in operating margin of 6.0% compared to 7.9% in fourth quarter 2011. The decline in operating margin was principally due to lower volume in the fourth quarter 2012 compared to the impact from record net sales in the same period last year. In addition, non-recurring acquisition-related expenses and integration costs combined with increased healthcare costs and depreciation expense further reduced operating margin by a total of approximately 100 basis points. Excluding the non-cash pension settlement charges described above, gross margin was 23.5% and 23.3% and operating margin was 9.4% and 11.1% for the fourth quarters of 2012 and 2011, respectively.

Net income during the quarter was $3.7 million compared to $5.1 million in the fourth quarter 2011 and earnings per share were $0.17 and $0.24 for the respective periods. Excluding the non-cash pension settlement charges noted above, earnings were $0.26 and $0.34 per share for the respective periods.

The Company’s backlog of orders was $143.4 million at December 31, 2012 compared to $155.5 million a year ago and $146.7 million at September 30, 2012. The expected decrease in backlog from December 31, 2011 was primarily due to anticipated shipments during the twelve months ending December 31, 2012 combined with anticipated lower incoming orders from the construction, municipal, industrial and OEM markets. The Company could see the backlog increase in the second quarter of 2013 by approximately $70 million based on a letter of intent to the Company to supply major flood control pumps to a member of a joint venture construction group for a significant New Orleans flood control project as announced by the Company October 1, 2012. The award of this joint venture project has been protested by unsuccessful bidders and is expected to be resolved by mid-2013.

The Company’s balance sheet continues to remain strong with $20.4 million of cash and short-term investments at December 31, 2012. The Company generated $32.6 million in operating cash flow during 2012 compared to $21.1 million during 2011 and has excellent liquidity and flexibility. Working capital increased 5.6% to $110.9 million at December 31, 2012 compared to $105.0 million a year ago largely due to increased inventory, including additional engines to reduce future delivery lead-times, and from the two acquisitions made during the latter part of 2012. Short-term debt totaled $22.0 million at year end 2012 which includes $17.0 million borrowed by the Company in the fourth quarter 2012 to finance the acquisition of American Turbine.

Jeffrey S. Gorman, President and CEO said, “We are pleased with again achieving record sales primarily as a result of organic revenue growth. However, incoming orders have moderated from record levels experienced during 2011 in some key end markets. Although we are encouraged by our growth in the agriculture, petroleum and international markets this past year, we anticipate the municipal and construction markets to remain somewhat sluggish for the near future due to the ongoing uncertain domestic economy. Taking advantage of our strong financial flexibility, the Company continued to make strategic investments during the year for future growth. These included the international acquisition of South Africa-based Pumptron and the domestic acquisition of Texas-based American Turbine which complement and broaden our existing pump portfolio and provide additional opportunities for global expansion of our major water markets and certain non-water markets. Also, we are very proud to celebrate the 80^th anniversary of the Company’s founding during 2013 and we remain committed to continue creation of long-term value for our shareholders.”
