Item 5.01

Change of Control of Registrant

As previously announced, On May 15, 2016, Nanosphere, Inc. (the “Company”), Luminex Corporation, a Delaware corporation (“Luminex”), and Commodore Acquisition, Inc., a Delaware corporation and a wholly-owned subsidiary of Luminex (“Merger Subsidiary”) entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the Merger Agreement, on June 2, 2016 Luminex commenced a cash tender offer (the “Offer”) to acquire all of the shares of the Company’s common stock, par value $0.01 per share (“Common Stock”) for a purchase price of $1.70 per share, net to the holders thereof, in cash (the “Offer Price”), without interest, subject to the terms and conditions of the Merger Agreement. Capitalized terms used herein and not defined shall have the meaning ascribed to them in the Merger Agreement.

The Offer and withdrawal rights expired at 12:00 Midnight, Eastern Daylight Time, at the end of June 29, 2016. The Depositary has advised Luminex and Merger Subsidiary that, as of the expiration of the Offer, a total of 45,252,609 Shares had been validly tendered into and not validly withdrawn from the Offer (not including 953,173 Shares tendered pursuant to notices of guaranteed delivery), representing approximately 85.6% of the currently outstanding Shares. The number of Shares validly tendered and not validly withdrawn pursuant to the Offer satisfies the Minimum Condition. All conditions to the Offer having been satisfied or waived, Purchaser has accepted for payment and will promptly pay for all Shares validly tendered into and not withdrawn, in accordance with the terms of the Offer.

As a result of its acceptance of the Shares tendered in the Offer, Merger Subsidiary acquired sufficient Shares so that the Merger was consummated on June 30, 2016, without the affirmative vote of the Company’s stockholders, pursuant to Section 251(h) of the DGCL. In the Merger, each Share issued and outstanding immediately prior to the Effective Time (other than Shares held by any Company stockholders who properly demanded appraisal of such Shares in connection with the Merger as described in Item 8 – “Additional Information” of the Company’s Schedule 14D-9 as filed with the SEC on June 2, 2016 under the heading Appraisal Rights) was converted into the right to receive cash in an amount equal to the Offer Price, without interest, less any applicable withholding taxes. All Shares will be delisted from NASDAQ and deregistered under the Exchange Act.

Item 5.03

Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

In connection with the completion of the Merger described above under Item 5.01, on June 30, 2016, the Company filed a Certificate of Merger with the Delaware Department of State. A copy of the Certificate of Merger is filed herewith as Exhibit 3.1.
