CSS INDUSTRIES, INC. ANNOUNCES THE SALE OF THE HALLOWEEN PORTION OF ITS PAPER MAGIC BUSINESS

CSS Industries, Inc. (NYSE: CSS) announced today that it has sold the Halloween portion of its Paper Magic Group, Inc. (“PMG”) business to Gemmy Industries (HK) Limited (“Gemmy”). Under the terms of the purchase agreement executed yesterday, Gemmy acquired, upon execution of the agreement, certain tangible and intangible assets associated with PMG’s Halloween business. As part of the transaction, PMG will remain responsible for the manufacture, sale and distribution of all PMG Halloween products (such as Halloween masks, costumes, make-up and novelties) for the Halloween 2012 season. Stifel Nicolaus Weisel served as exclusive financial advisor to CSS in the transaction.

“As part of a continuing review of our PMG seasonal business, we decided that the sale of PMG’s Halloween business was appropriate at this time, as it will allow management to focus our time and resources on more profitable product categories,” said Christopher J. Munyan, President and Chief Executive Officer of CSS. As a result of this transaction, CSS expects to incur pre-tax charges, net of proceeds, in a range of approximately $6.0 to $7.6 million, all as further described in CSS’ Form 8-K filed today.

“Because the closing of this transaction occurs as we are completing our shipment of Halloween 2012 products to our customers,” said Mr. Munyan, “we agreed that CSS will finish its commitments to our customers for the Halloween 2012 season, and that Gemmy will provide Halloween products for the Halloween 2013 season and thereafter. We also agreed that Gemmy will be able to use the “PMG Halloween” name for the Halloween 2013 season.”

“Gemmy is a highly respected provider of consumer décor products, including Halloween décor products,” continued Mr. Munyan, “and we believe that, as a result of this transaction, Gemmy will be able to enhance its product offerings.”

CSS is a consumer products company primarily engaged in the design, manufacture, procurement, distribution and sale of seasonal and all occasion social expression products, principally to mass market retailers. These seasonal and all occasion products include decorative ribbons and bows, boxed greeting cards, gift tags, gift wrap, gift bags, gift boxes, gift card holders, decorative tissue paper, decorations, classroom exchange Valentines, floral accessories, Easter egg dyes and novelties, craft and educational products, stickers, memory books, stationery, journals, note cards, infant and wedding photo albums, scrapbooks, and other gift items that commemorate life’s celebrations.
