LANCASTER COLONY REPORTS FISCAL YEAR AND FOURTH QUARTER RESULTS

COLUMBUS, Ohio, Aug. 19 — Lancaster Colony Corporation (Nasdaq: LANC) today reported results for the company’s fiscal year ended June 30, 2010, including these highlights:

•

Net sales increased 0.5 percent to $1,057 million versus $1,051 million last year.

•

Net income totaled a record $115.0 million or $4.07 per diluted share. Prior year net income totaled $89.1 million, or $3.17 per diluted share. Fiscal 2010 results included pretax income of $0.9 million (two cents per share after taxes) associated with a second quarter distribution under the Continued Dumping and Subsidy Offset Act (CDSOA). In fiscal 2009, the pretax CDSOA distribution was $8.7 million (20 cents per share after taxes).

•

The cash dividend was increased for the 47th consecutive year, and 80,000 shares were repurchased at a cost of approximately $4.4 million.

•

The balance sheet remained strong with no debt outstanding. The company’s $160 million unsecured revolving credit facility was unused and fully available.

Fourth Quarter Results

Highlights of the fourth quarter ended June 30, 2010 included the following:

•

Net sales decreased two percent to $248 million versus $253 million in the year ago quarter.

•

Specialty Foods sales totaled $217.3 million, a decline of four percent from last year’s record fourth quarter total. This decline was primarily due to weaker foodservice volume and cost-driven price decreases. Retail sales declined slightly, with the earlier Easter this year shifting sales to the third fiscal quarter. Lower sales volumes, greater investment in trade support for certain frozen lines, increased freight and somewhat less efficient operations contributed to segment operating income declining by 18 percent to $38.2 million from the prior year’s record of $46.8 million.

•

Glassware and Candles sales increased 15 percent to $30.7 million primarily due to higher candle sales to the mass market. The segment’s quarterly operating loss improved to less than $0.1 million compared to $0.9 million a year ago. The benefits from higher sales and greater production volumes were mitigated by higher input costs, especially for paraffin wax.

•

Fourth quarter net income totaled $22.8 million, or $0.81 per diluted share, versus the year ago net income of $28.4 million, or $1.01 per diluted share.

Chairman and CEO John B. Gerlach, Jr. said, “Persistent economic weakness continues to challenge consumer spending, especially for food consumed away from home. The Easter timing

was also an issue for our fourth quarter retail food sales. Although our fourth quarter is one of seasonal candle weakness, we were pleased to see further increased sales of our high-quality, value-oriented candles. The quarter’s operating income was impacted by softer food sales and increased trade promotional activities in addition to our planned consumer-focused marketing efforts, which are part of our long-term investment in our branded retail food products.”

Fiscal 2010 Commentary

Mr. Gerlach said, “For the year, we achieved record operating income and net income, with meaningful bottom-line improvement in both operating segments. Better Specialty Foods results led this increase as we enjoyed higher retail sales volumes and lower average material costs despite higher consumer marketing and trade promotional investments. We were also pleased with the improvement in our candle operations.”

Fiscal 2011 Commentary

Mr. Gerlach continued, “We begin the new year with well-positioned food brands, balance sheet flexibility and future growth potential from new product development and greater geographic penetration. New Specialty Foods retail products include Marzetti Otria™ Greek yogurt-based vegetable dips, New York brand Ciabatta garlic loaf, and Sister Schubert’s soft multi-grain frozen rolls. We believe that sales growth is achievable in fiscal 2011, but our earnings optimism is tempered by economic hurdles faced by consumers, planned expansion of marketing activities, rising paraffin wax costs and potentially higher food commodity and packaging costs. Our unwavering focus on efficiently providing consumer-pleasing products and strong customer service should help yield continued strong shareholder returns.”
