Supplement to the Proxy Statement for the Special Meeting of Shareholders to be held on September 19, 2012.

This is a supplement to the proxy statement dated August 20, 2012 (the “proxy statement”) of Brightpoint, Inc. (“BrightPoint,” “we” or the “Company”) that was mailed to BrightPoint shareholders in connection with the solicitation of proxies for use at the special meeting of shareholders to be held at BrightPoint’s corporate headquarters located at 7635 Interactive Way, Suite 200, Indianapolis, IN 46278 on Wednesday, September 19, 2012 at 9:00 a.m. local time. The purpose of the special meeting is (1) to consider and vote on a proposal to approve the Agreement and Plan of Merger, dated as of June 29, 2012, among Ingram Micro Inc. (“Ingram Micro”), Beacon Sub, Inc., a wholly owned subsidiary of Ingram Micro (“Merger Sub”), and BrightPoint, as it may be amended from time to time, pursuant to which Merger Sub will be merged with and into BrightPoint (the “merger”), with BrightPoint surviving the merger as a wholly owned subsidiary of Ingram Micro (the “merger agreement”); (2) to consider and vote on a non-binding, advisory basis, to approve the compensation that may be paid or otherwise become payable to our named executive officers that is based on or otherwise relates to the merger as disclosed in the proxy statement under the heading “The Merger — Interests of BrightPoint’s Directors and Executive Officers in the Merger”; and (3) to consider and vote upon a proposal to adjourn the special meeting, if necessary or appropriate, to permit further solicitation of proxies if there are not sufficient votes at the time of the special meeting to approve the merger agreement.

The Board of Directors of BrightPoint (the “Board”) established August 14, 2012 as the record date for the purpose of determining the shareholders who are entitled to receive notice of, and to vote at (in person or by proxy), the special meeting.

After careful consideration, the Board unanimously (i) determined that the merger agreement and the merger are advisable and in the best interests of BrightPoint and its shareholders and (ii) adopted, approved and declared advisable the execution, delivery and performance of the merger agreement and the merger.

THE BOARD OF DIRECTORS OF BRIGHTPOINT UNANIMOUSLY RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF THE MERGER AGREEMENT, FOR THE APPROVAL, ON A NON-BINDING ADVISORY BASIS, OF COMPENSATION THAT MAY BE PAID OR BECOME PAYABLE TO OUR NAMED EXECUTIVE OFFICERS THAT IS BASED ON OR OTHERWISE RELATES TO THE MERGER; AND FOR THE PROPOSAL TO ADJOURN THE SPECIAL MEETING, IF NECESSARY OR APPROPRIATE, TO PERMIT FURTHER SOLICITATION OF PROXIES IF THERE ARE NOT SUFFICIENT VOTES AT THE TIME OF THE SPECIAL MEETING TO APPROVE THE MERGER AGREEMENT. INFORMATION ABOUT VOTING OR REVOKING A PROXY APPEARS ON PAGE 22 OF THE PROXY STATEMENT.

Litigation Related to the Merger

As described on page 61 of the proxy statement, BrightPoint received notice of the filing of two putative class action complaints commenced in the District Court for the Southern District of Indiana. In the first action, the plaintiff sued BrightPoint, its directors, Ingram Micro and Merger Sub for alleged violations of Sections 14 and 20 of the Securities Exchange Act of 1934, based on alleged omission of certain information contained in the preliminary filing of this proxy statement. In the second action, two plaintiffs sued BrightPoint and its directors alleging the same federal securities claims and asserting that BrightPoint’s directors breached their fiduciary duties by, among other things, purportedly failing to conduct a fair process for the sale of BrightPoint and accepting a purchase price that was too low. These plaintiffs also allege that BrightPoint aided and abetted the directors’ purported breaches of their fiduciary duties. The plaintiffs in both putative class actions seek, among other things, monetary damages, injunctive relief (including enjoining the merger) and attorneys’ and other fees and expenses. On August 10, 2012, BrightPoint moved to dismiss the first action described above for failure to state a claim under the federal securities laws.

BrightPoint has also received a letter on behalf of a BrightPoint shareholder that requests that BrightPoint incorporate certain disclosures relating to the merger into the definitive proxy statement.

On September 4, 2012, BrightPoint entered into a memorandum of understanding memorializing the terms of a settlement of all litigation, which would include the dismissal with prejudice of all claims against all of the defendants. The proposed settlement is conditional upon, among other things: the dismissal with prejudice of the litigation without the award of any damages, costs, fees or the grant of any other further relief, except for the award of fees and expenses pursuant to the memorandum of understanding; the entry of a final judgment in the actions (i) approving the settlement (including a provision enjoining all members of the class from asserting any of the released claims), (ii) providing for the dismissal of the actions and (iii) approving the release by the class to the defendants; and consummation of the merger and final approval of the proposed settlement by the court. In connection with the settlement and as provided in the memorandum of understanding, the parties contemplate that plaintiffs’ counsel will seek an award of attorneys’ fees and expenses as part of the settlement. There can be no assurance that the merger will be consummated, that the parties ultimately will enter into a settlement or that the court will approve the settlement. In such event, the memorandum of understanding and the proposed settlement as contemplated by the memorandum of understanding shall be null and void. The settlement will not affect the amount of the merger consideration that BrightPoint shareholders are entitled to receive in the merger.

The defendants deny that they have committed any violations of law or otherwise failed to act in a proper manner with respect to the facts and claims alleged in the actions and specifically deny that any further supplemental disclosure was required under any applicable rule, statute, regulation or law. The defendants have entered into the memorandum of understanding because the proposed settlement would eliminate the risk, burden and expense of further litigation, would resolve all of the claims and permit the merger to be consummated as scheduled without risk of delay and would permit BrightPoint’s shareholders to receive the consideration provided for in the merger agreement.

Additional Disclosures

As contemplated by the proposed settlement, BrightPoint is providing certain additional disclosures that are supplemental to those contained in the proxy statement previously mailed to you. This supplemental information should be read in conjunction with the proxy statement, which we urge you to read in its entirety. As noted above, none of the defendants has admitted wrongdoing of any kind, including but not limited to inaccuracies or inadequacies in any disclosure, the materiality of any disclosure that the plaintiffs contend should have been made, any breach of any fiduciary duty, or aiding or abetting any of the foregoing. The additional disclosures are as follows:

Blackstone’s Selected Companies Analysis

As described in detail on pages 39-41 of the proxy statement, Blackstone reviewed and compared certain financial information of BrightPoint to corresponding financial information, ratios and public market multiples for selected publicly traded companies. Below is a chart indicating the multiples for each selected company Blackstone used in its Selected Companies Analysis:

Blackstone’s Illustrative Stand-Alone Discounted Cash Flow Analysis

As described in detail on page 41 of the proxy statement, Blackstone conducted an illustrative stand-alone discounted cash flow analysis. The first paragraph under the heading “Illustrative Stand-Alone Discounted Cash Flow Analysis” on page 41 of the proxy is replaced with the following paragraph:

Blackstone conducted an illustrative discounted cash flow analysis for the company on a standalone basis, which is designed to estimate an implied value of a company by calculating the present value of the estimated future unlevered free cash flows and terminal value of the company. Blackstone calculated a range of implied equity values per share of BrightPoint common stock based on forecasts of future unlevered free cash flows for the second half of fiscal year 2012 through fiscal year 2017 provided by management of BrightPoint. Blackstone first calculated unlevered free cash flows (calculated as earnings before interest and taxes, less taxes, plus depreciation and amortization, less the amount of any increase or plus the amount of any decrease in net working capital, and less capital expenditures) of BrightPoint for fiscal years 2012 to 2017, using an

end-of-year convention (i.e., assuming all cash flows occur at the end of each year). The calculation of unlevered free cash flows used an assumed tax rate of 30% (which tax rate was provided by BrightPoint and assumed conservative use of Brightpoint’s net operating losses). Blackstone then calculated a terminal value for BrightPoint by applying a range of terminal last twelve month (“LTM”) EBITDA multiples of 4.0x to 6.0x (which range was selected based on Blackstone’s professional judgment after consideration of the trading multiples for the selected companies) to BrightPoint management’s forecast of EBITDA for fiscal year 2017 for BrightPoint. These unlevered free cash flows and terminal values were then discounted to present values as of June 30, 2012 using a range of discount rates of 9.5% to 10.5% (which range was selected based on Blackstone’s professional judgment and derived from an analysis of the estimated weighted average cost of capital using industry comparables) to calculate a range of implied total enterprise values for BrightPoint. These total enterprise values were further adjusted for BrightPoint’s net debt (forecasted as of June 30, 2012 per BrightPoint’s internal management projections), minority interest, and the book value of the equity investment in affiliate, to calculate a range of implied equity values. Blackstone did not account for share based compensation in its analysis. This implied equity value range was then divided by 72,664,000, which represents the fully diluted number of outstanding shares of BrightPoint common stock as of June 26, 2012, as reported by BrightPoint to Blackstone, to calculate a range of implied equity values per share.

Blackstone’s Selected Precedent Transactions Analysis

As described on pages 41-42 of the proxy statement, Blackstone performed a selected precedent transactions analysis. The first chart on page 42 is replaced with the following chart, which includes a column entitled “Transaction Value/LTM Revenue”:
