GORMAN-RUPP REPORTS THIRD QUARTER 2013 RESULTS AND ANNOUNCES STOCK SPLIT AND CASH DIVIDEND INCREASE

Mansfield, Ohio – October 25, 2013 – The Gorman-Rupp Company (NYSE MKT: GRC) reports financial results for the third quarter and nine months ended September 30, 2013.

Net sales during the third quarter 2013 increased 10.4% to $101.2 million compared to $91.6 million during the same period in 2012. Domestic sales increased 18.3% or $10.7 million while international sales decreased 3.3% or $1.1 million. The increase in sales in our water end markets of $1.8 million was primarily due to increased shipments for the agriculture and fire protection markets of $5.6 million, partially offset by decreased shipments for Gulf Coast flood control projects of $3.9 million. Sales in our non-water end markets of $7.7 million increased primarily due to shipments for the OEM market of $4.3 million related to power generation equipment and military applications and for the industrial market of $2.2 million.

Net sales for the nine months ended September 30, 2013 were a record $300.1 million compared to $287.0 million during the same period in 2012, an increase of 4.5%. The increase in water end market sales of $11.5 million was primarily due to shipments for the fire and agricultural markets and for Gulf Coast flood control projects in the first half of 2013. This increase was partially offset by reduced construction market demand for pumps from rental businesses as compared to this market’s strong sales early last year. Increased international shipments for the petroleum market were the major contributor to the increase in our non-water market sales of $1.5 million.

Due to continuing lump-sum retirement payments, the Company recorded a GAAP-required $490,000 non-cash pension settlement charge during the third quarter of 2013 relating to its defined benefit pension plan. The Company has recorded a total of $3.5 million in non-cash pension settlement charges during the first nine months of 2013. These required charges were driven by exceeding the actuarial payments threshold relating to retirees electing to receive lump-sum distributions during 2013. A non-cash pension settlement charge was not required to be recognized in 2012 until the actuarial payments threshold was exceeded in the fourth quarter.

Gross profit was $24.5 million for the third quarter 2013 resulting in gross margin of 24.2% compared to 23.8% in the same period last year. The increase in gross margin was principally due to sales mix changes during the current quarter. Operating income was $12.0 million resulting in operating margin of 11.9% compared to 11.0% in the third quarter 2012. Excluding the pension settlement charge described above, gross margin would have been 24.5% and operating margin would have been 12.4% for the third quarter of 2013.

Net income increased 18.5% during the quarter to $7.9 million compared to $6.7 million in the third quarter 2012 and earnings per share were $0.38 and $0.32 for the respective periods. Excluding the non-cash pension settlement charge of $0.02 per share, earnings would have been $0.40 for the third quarter 2013.

Gross profit was $72.2 million for the first nine months of 2013 resulting in gross margin of 24.1% compared to 24.8% in the same period last year. The decline in gross margin was principally due to the non-cash pension settlement charges described above of 70 basis points plus about 20 basis points due to increases in healthcare costs and depreciation expense. Operating income was $33.8 million resulting in operating margin of 11.3% compared to 12.8% in the first nine months of 2012. Excluding the pension settlement charge, gross margin would have been 24.8% and operating margin would have been 12.4% for the first nine months of 2013.

Net income was $22.9 million during the first nine months of 2013 compared to $24.5 million in the same period last year and earnings per share were $1.09 and $1.17 for the respective periods. Excluding the non-cash pension settlement charge of $2.3 million net of income taxes and equating to $0.11 per share, earnings would have been $1.20 per share for the current nine months.

The Company’s backlog of orders was $190.7 million at September 30, 2013 compared to $146.7 million a year ago and $143.4 million at December 31, 2012. The increase in backlog reflects the award of the Permanent Canal Closure Project (“PCCP”) contract of approximately $60.0 million to supply major flood control pumps to a member of a joint venture construction group for a significant New Orleans flood control project. The pumps are expected to be shipped primarily in the second half of 2014 and first half of 2015.

The Company’s balance sheet continues to remain strong and flexible as cash and short-term investments totaled $33.8 million and short-term bank debt was reduced to $9.0 million at September 30, 2013. Working capital increased 16.6% from December 31, 2012 to a record $129.3 million at September 30, 2013 principally due to increased 2013 net sales and debt reduction. The Company expects net capital expenditures for the fourth quarter of 2013 will be approximately $12.0 million, primarily for machinery and equipment.

Jeffrey S. Gorman, President and CEO said, “We delivered strong third quarter results driven by increased sales and profitability within a difficult business environment, as U.S. and global economic and political uncertainties continue to be a negative influence on capital goods investment within most of our markets. Although our fourth quarter is typically softer seasonally, we remain focused on providing high quality products with timely deliveries and are gaining confidence over the longer term. The PCCP contract should provide a positive impact on sales and earnings as we move into 2014 and 2015.”

At its October 24, 2013 meeting, the Board of Directors of the Company declared a five-for-four split of the Company’s Common Shares in the form of a distribution of one additional Common Share for each four Common Shares previously issued. The distribution will be made on December 10, 2013 to shareholders of record at the close of business on November 15, 2013.

Cash payments will be made to shareholders in settlement of fractional-share interests resulting from the distribution on the basis of the average of the high and low sales price of the Company’s Common Shares on the NYSE MKT Exchange on the record date (or, if there are no sales on the record date, then on the first preceding day on which there were sales), adjusted to reflect the distribution.

Computershare Investor Services, LLC, the Transfer Agent and Registrar for the Common Shares of the Company, will accept instructions from brokers and nominees regarding their requirements for the distribution until December 3, 2013.

After giving effect to the issuance of the additional Common Shares in the distribution, the most recent quarterly cash dividend rate of $0.10 per Common Share on a post-split basis would be equivalent to $0.08 per share.

In an additional action, the Board of Directors of the Company declared a quarterly cash dividend of $0.09 per share on the common stock of the Company, payabl e December 10, 2013, to shareholders of record November 15, 2013. The cash dividend is payable on post-split shares and represents a 12.5% increase over the equivalent post-split dividend paid during the previous quarter. This marks the 255th consecutive dividend paid by The Gorman-Rupp Company and the 41st consecutive year of increased dividends paid to its shareholders.

“Our Board approved a five-for-four stock split at its regular quarterly meeting, which is the tenth split in Gorman-Rupp’s history, and voted to increase our quarterly cash dividend, said Jeffrey S. Gorman, President and CEO. These decisions are responses to our solid earnings, confidence in our continued long-term growth and our strong balance sheet. We believe these actions will reward our shareholders and enhance the investment appeal of our Common Stock.”
