This Amendment No. 3 to Schedule 14D-9 (this “Amendment”) amends and supplements the Solicitation/Recommendation Statement on Schedule 14D-9 filed with the Securities and Exchange Commission (the “SEC”) on January 31, 2020 and subsequently amended by Amendment No. 1 filed with the SEC on February 4, 2020 and Amendment No. 2 filed with the SEC on February 11, 2020 (together with the Exhibits or Annexes thereto and as amended or supplemented from time to time, the “Schedule 14D-9”) by CSS Industries, Inc., a Delaware corporation (the “Company”). The Schedule 14D-9 relates to a tender offer by TOM MERGER SUB INC., a Delaware corporation (“Merger Sub”) and direct, wholly owned subsidiary of IG Design Group Americas, Inc., a Georgia corporation (“Parent”) and wholly owned subsidiary of IG Design Group Plc, a public limited company incorporated and registered in England and Wales (“Design Group”), to purchase all of the issued and outstanding shares of common stock, par value $0.10 per share, of the Company for a purchase price of $9.40 per share, net to the seller in cash, without interest and subject to any applicable tax deduction or withholding, upon the terms and subject to the conditions set forth in the the Offer to Purchase, dated January 31, 2020 (as may be amended or supplemented from time to time), and in the related Letter of Transmittal (as may be amended or supplemented from time to time), which were filed as Exhibits (a)(1)(A) and (a)(1)(B) to the Schedule 14D-9, respectively.

Capitalized terms used, but not otherwise defined, in this Amendment shall have the meanings ascribed to them in the Schedule 14D-9. The information in the Schedule 14D-9 is incorporated into this Amendment by reference to all applicable items in the Schedule 14D-9, except that such information is hereby amended and supplemented to the extent specifically provided herein.

Explanatory Note

As previously disclosed, subsequent to the Company filing the Schedule 14D-9 with the SEC, three complaints were filed by purported stockholders of the Company. Two complaints, Shiva Stein vs. CSS Industries, Inc. et. al. (1:20-cv-00171-RGA), filed February 3, 2020 (the “Stein Complaint”), and Joseph Post vs. CSS Industries, Inc. et. al. (1:20-cv-00192-RGA), filed February 10, 2020 (the “Post Complaint”), were filed in the United States District Court for the District of Delaware and the third complaint, Adrienne Halberstam vs. CSS Industries, Inc. et. al. (1:20-cv-01075), filed February 7, 2020 (the “Halberstam Complaint” and together with the Stein Complaint and the Post Complaint, the “Complaints”) was filed in the United States District Court for the Southern District of New York. Each of the Complaints name as defendants the Company and its current directors. In addition, the Post Complaint names Merger Sub, Parent and Design Group as defendants. All of the Complaints generally allege that the Schedule 14D-9 omits purportedly material information and seek, among other things, to enjoin the consummation of the transactions described in the Schedule 14D-9, or, in the event such transactions are consummated, rescission or rescissory damages, and costs and fees relating to the lawsuit. The Post Complaint further seeks judgments (i) directing the defendants to file a Schedule 14D-9 Solicitation/Recommendation Statement that does not contain any untrue statements of material fact and states all material facts required in it or necessary to make the statements within it not misleading and (ii) declaring that the defendants violated Sections 14(e), 14(d), and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder. While it is not possible to predict the outcome of litigation matters with certainty, the Company believes that the claims raised in the Complaints are without merit.

While the Company believes that the disclosures set forth in the Schedule 14D-9 comply fully with applicable law, to moot certain of plaintiffs’ disclosure claims in the Complaints, to avoid nuisance, potential expense and delay and to provide additional information to its stockholders, the Company has determined to voluntarily supplement the Schedule 14D-9 with the below disclosures. Nothing in the below supplemental disclosures shall be deemed an admission of the legal necessity or materiality under applicable law of any of the disclosures set forth herein or in the Schedule 14D-9. To the contrary, the Company denies all allegations in the Complaints that any additional disclosure was or is required.

Item 2. Identity and Background of Filing Person

Item 2 of the Schedule 14D-9 is hereby amended and supplemented by adding the following paragraph after the second paragraph in the subsection entitled “Tender Offer”:

“On February 11, 2020, Design Group obtained the Pre-Emptive Rights Waiver, and on February 12, 2020, Design Group completed the equity financing. As a result of the completion of the equity financing, the Funding Condition has been satisfied.”

Representatives of Guggenheim Securities also shared with the Board the in-bound expression of interest received from Party D and advised the Board that, as had been shared with

the Special Committee on October 21, 2019, the call had been preliminary in nature. Guggenheim Securities also informed the Board of the October 28, 2019 call with Party D and advised that, following such call, it had received no further communication from Party D. In light of that advice, and the exclusivity undertaking with Design Group, the Special Committee decided not to engage with Party D. The Board also discussed the potential adoption of a stockholder rights plan, consistent with the form of such a plan that the Company maintained “on the shelf,” with Guggenheim Securities recommending that such a plan should be adopted in light of the activities of Ribs and the desirability of protecting the Company’s ability to consummate the proposed transaction with Design Group. After discussion, the Board requested that Morgan Lewis and Guggenheim Securities prepare the necessary materials for adoption of a stockholder rights plan for presentation to the Board at a subsequent meeting.”
