NORCROSS, GA & FORT WORTH, TX, August 19, 2011 – Immucor, Inc. (Nasdaq: BLUD) (the “Company”) and TPG Capital, L.P. (“TPG Capital”) today announced the successful acquisition of the Company by IVD Acquisition Corporation, an affiliate of TPG Capital, for $27.00 per share in cash, or approximately $1.939 billion in the aggregate.

“The successful closing of this transaction is a significant accomplishment for Immucor,” said Joshua H. Levine, President and Chief Executive Officer of Immucor. “Through this partnership with TPG, we will have additional opportunities to create value, expand our global footprint and develop innovative products that improve the practice of transfusion medicine.”

On July 5, 2011, the Company announced that the Company entered into a definitive agreement to be acquired by investment funds managed by TPG Capital. Pursuant to the merger agreement, IVD Acquisition Corporation commenced a tender offer on July 15, 2011 to acquire all of the outstanding shares of common stock of the Company at a price of $27.00 per share, net to the seller in cash, payable without interest and less any applicable withholding taxes. The tender offer and withdrawal rights expired at 5:00 P.M., Atlanta, Georgia time, on Thursday, August 18, 2011, and the depositary has advised that, as of the expiration of the offer, 61,549,994 shares of common stock had been validly tendered and not validly withdrawn, representing approximately 87% of the outstanding shares of common stock of the Company on a fully-diluted basis. All of these shares have been accepted for payment by IVD Acquisition Corporation. Pursuant to the merger agreement, IVD Acquisition Corporation purchased additional shares of common stock of the Company at the same price paid in the tender offer pursuant to the “top-up” option.

Today, following the consummation of the tender offer and IVD Acquisition Corporation’s exercise of the “top-up” option, IVD Acquisition Corporation was merged with and into the Company with the Company surviving the merger, in accordance with the merger agreement. In the merger, each share, other than shares held by IVD Holdings Inc., IVD Acquisition Corporation or the Company or shares held by the Company’s shareholders who validly exercise dissenters’ rights under Georgia law, not previously purchased in the tender offer was converted into the right to receive $27.00, net to the seller in cash.

As a result of the completion of the merger, the Company’s common stock will cease to be traded on The NASDAQ Global Select Market.
