Good morning. Joining me on our call today are Norman Ferber, Chairman of the Board; Michael O'Sullivan, President and Chief Operating Officer; Gary Cribb, Executive Vice President, Stores and Loss Prevention; John Call, Group Senior Vice President and Chief Financial Officer; and Bobbi Chaville, Senior Director, Investor Relations.
We will begin with a brief review of our first quarter performance, followed by our outlook for the second quarter and fiscal year. We'll conclude with some comments about our longer-term growth prospects. Afterwards, we'll be happy to respond to any questions you may have.
We are pleased with our much better-than-expected financial results in the first quarter. Our robust sales and earnings were driven mainly by our ongoing ability to deliver a wide array of fresh and exciting name-brand bargains to today's value-focused consumers. In addition, we believe that favorable weather across many of our markets also contributed to our above-planned performance. Our ability to operate our business with lower in-store inventories and strictly controlled expenses also continued to enhance both sales and profit margins.
Earnings per share for the 13 weeks ended April 28, 2012 were $0.93, up from a split-adjusted $0.74 in the prior year. These results represent a 26% increase on top of a 28% gain in the same period last year. Net earnings for the 2012 first quarter grew 21% to $208.6 million. Sales rose 14% to $2,357,000,000, with comparable store sales up 9% on top of 3% growth in the first quarter of 2011. Merchandise and geographic trends were broad-based. Juniors and Accessories were the best-performing categories, while Florida remained the top region.
Earnings before interest and taxes grew to a record 14.4% of sales, up about 70 basis points on top of an exceptional 160-basis point increase in the prior year. Our improved profit margin versus last year was driven primarily by leverage on expenses from the strong gains in same-store sales and higher merchandise gross margin. John will provide some additional color on these operating margin trends in a few minutes.
As we entered the first quarter, total consolidated inventories declined about 3% compared to the prior year, mainly due to lower packaway levels that were about 45% of total inventories, down from 48% at this time last year. More importantly, average in-store inventory declined about 9%. For the balance of the year, we are targeting a mid-single-digit percentage decrease in selling store inventories compared to 2011.
Like Ross, dd's is also benefiting from our ability to flow a larger percentage of fresh product to our stores by operating on lower inventory levels. dd's above-planned sales and margin in the first quarter reflect that its merchandise offerings continue to resonate well with its value-focused customers. Our store expansion program is on track, with a total of about 80 locations scheduled to open during 2012, comprised of 60 Ross and 20 dd's DISCOUNTS.
Now John will provide further color on our first quarter results and details on our second quarter 2012 guidance.
