LINDSAY CORPORATION REPORTS FISCAL 2007 FIRST QUARTER RESULTS

OMAHA, Neb., December 20, 2006—Lindsay Corporation (NYSE: LNN), a leading manufacturer of irrigation systems and infrastructure products, today announced results for its fiscal 2007 first quarter ended November 30, 2006.

First Quarter Results
First quarter fiscal 2007 total revenues increased 30 percent to $51.5 million from $39.5 million for the year-ago period. Net earnings were $1.8 million or $0.15 per diluted share, compared with $511,000, or $0.04 per diluted share, in the prior year’s first quarter. The quarter includes the results from Barrier Systems Inc. (BSI), which was acquired on June 1, 2006.

Total irrigation equipment revenues increased 11 percent to $38.0 million from $34.1 million in the prior fiscal year’s first quarter. Domestic irrigation revenues increased 11 percent, while international irrigation revenues improved 12 percent from the prior year’s quarter. Infrastructure revenues were $13.6 million compared with $5.4 million in the prior year period, with all of the increase resulting from the inclusion of BSI.

Gross margin improved to 24.2 percent from 18.8 percent a year ago, primarily due to inclusion of BSI’s higher margin products. Operating expenses of $9.9 million in the first quarter increased $2.8 million over the prior year period due primarily to inclusion of BSI and higher medical expenses. Operating income during the quarter was $2.6 million compared with $363,000 in the prior year period.

Rick Parod, president and chief executive officer, commented, “While it is still early in the irrigation season, higher agricultural commodity prices provide solid fundamental drivers for the upcoming season. In addition, we are pleased with the strength of our infrastructure revenues with the addition of BSI.”

Lindsay’s backlog of unshipped orders at November 30, 2006, was $24.6 million compared with $20.9 million at November 30, 2005. Irrigation backlog declined $2.6 million while infrastructure backlog increased $6.3 million, with all the increase attributable to the inclusion of BSI.

Shareholders’ equity at November 30, 2006 was $123.7 million or $10.64 per outstanding common share, compared with $109.8 million, or $9.53 per outstanding common share at November 30, 2005. Cash and marketable securities at November 30, 2006 were $45.9 million compared with $49.3 million at November 30, 2005.

Outlook
Parod added, “Our first fiscal quarter precedes our typical selling season and is not traditionally a reliable indicator of fiscal year revenues. Demand for crops supporting bio fuel production however, is expected to reduce crop inventories, moving prices higher which we believe strengthens demand for our irrigation products. “

Parod concluded, “I am pleased with the results of our infrastructure segment strengthened recently with the addition of BSI, and we remain focused on our growth opportunities from additional acquisitions. We will continue to leverage our strong cash flows and financial flexibility to create shareholder value through a balance of organic growth opportunities,

accretive acquisitions, share repurchases, and dividend payments.”
