Exhibit 99.4

Dear IEC Suppliers,

We are writing to provide you a courtesy notification regarding the recently announced agreement between IEC Electronics Corp (NASDAQ: IEC) and Creation Technologies. Attached you will find a copy of the press release.

I want to make sure that you have some basic facts about this possible transaction:

• Creation Technologies (www.creationtech.com) intends to acquire IEC Electronics. Creation is a financially strong EMS company with 3,200 employees in 10 sites located across the USA, Canada, Mexico, and China.

• Creation has a strong employee culture grounded in their 6 core values: Entrepreneurship, Boldness, Preparedness, Integrity, Openness, and Respect. The company has won Circuit Assembly’s awards for customer service for seven consecutive years. Creation was attracted to IEC because of our strong reputation in the A&D market, our strategic positioning in the medical and tech industrial sectors, as well as our longstanding customer relationships.

• The acquisition is premised on a broadening of services that the combination of the two companies can provide, it builds a larger, more successful, more global, EMS company. There are currently no planned site closures or rationalizations as a result of this combination.

Assuming a successful completion of the transaction, IEC will become a wholly-owned subsidiary of Creation Technologies. Creation is eager to partner with us and help us grow as we continue to build on the world class products and services that we offer. We do not anticipate any interruption to our supplier relationships and expect that this proposed transaction will only have a positive effect on our on-ongoing operations.

Please do not hesitate to reach out to your IEC supply chain contact with any questions or concerns.

Sincerely,

Jeffrey T. Schlarbaum

President & Chief Executive Officer

(“Parent”), will commence a tender offer for all of the Company’s outstanding shares of common stock, par value $0.01 per share (the “Common Stock”). The tender offer for Common Stock has not yet commenced. This communication is neither an offer to buy nor the solicitation of an offer to sell any securities. It is also not a substitute for the tender offer materials that Purchaser will file with the U.S. Securities and Exchange Commission (“SEC”) upon commencement of the tender offer. The solicitation and the offer to buy shares of Common Stock will be made only pursuant to an offer to purchase and related materials that Purchaser intends to file with the SEC. At the time the tender offer is commenced, Purchaser will file a Tender Offer Statement on Schedule TO with the SEC, and thereafter the Company will file a Solicitation/Recommendation Statement on Schedule 14D-9 with respect to the tender offer. The Tender Offer Statement on Schedule TO (including an offer to purchase, a related letter of transmittal and other offer documents) and the Solicitation/Recommendation Statement on Schedule 14D-9 will contain important information that should be read carefully and considered before any decision is made with respect to the tender offer.
