Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following unaudited pro forma condensed combined financial statements have been prepared to illustrate the effect of the Proposed Acquisition and the Debt Financing (as defined herein). The unaudited pro forma condensed combined financial statements have been prepared for informational purposes only and are not necessarily indicative of what the combined company’s condensed combined financial position or results of operations actually would have been had the Proposed Acquisition and the Debt Financing been completed as of the dates indicated below. In addition, the unaudited pro forma condensed combined financial statements do not purport to project the future financial position or operating results of the combined company.

The unaudited pro forma condensed combined balance sheet gives effect to the Proposed Acquisition and the Debt Financing as if those events had occurred on October 31, 2016, while the unaudited pro forma condensed combined statements of income for the year ended January 31, 2016 and the nine months ended October 31, 2016 each give effect to the Proposed Acquisition and the Debt Financing as if those events had occurred on February 1, 2015. The historical financial statements have been adjusted in the unaudited pro forma condensed combined financial statements to give effect to events that are (i) directly attributable to the Proposed Acquisition and the Debt Financing, (ii) factually supportable, and (iii) with respect to the statements of income, expected to have a continuing impact on the combined company. The unaudited pro forma condensed combined statements of income do not reflect any non-recurring charges directly related to the Proposed Acquisition and the Debt Financing that the combined company may incur upon completion of the Proposed Acquisition and the Debt Financing. Further, because the tax rate used for these unaudited pro forma condensed combined financial statements is an estimated statutory tax rate, it will likely vary from the actual effective rate in periods subsequent to the completion of the Proposed Acquisition and the Debt Financing.

Until the Proposed Acquisition is completed, both companies are limited in their ability to share information with each other. Therefore, the preliminary purchase price allocation was based on discussions with Avnet’s management, Tech Data’s historical experience, data that were available through publicly available information and Tech Data’s due diligence review of the Acquired Business (as defined herein). Each of the adjustments is preliminary and is based on certain estimates and currently available information and is subject to further adjustments as additional information becomes available and as additional analyses are performed. Management believes that all significant adjustments necessary to reflect the effects of the Proposed Transaction and the Debt Financing are included in the accompanying unaudited pro forma condensed combined financial statements and are deemed to be reasonable.

Upon completion of the Proposed Acquisition, additional valuation procedures are expected to be performed and any increases or decreases in the fair value of the assets acquired or liabilities assumed will result in adjustments to the unaudited pro forma condensed combined financial statements until the purchase price allocation is finalized. These adjustments could be material. The preliminary purchase price allocation has been made solely for the purpose of preparing the accompanying unaudited pro forma condensed combined financial statements and is not necessarily indicative of what the actual combined financial position or results of operations of Tech Data and the Acquired Business would have been as of and for the periods presented, nor does it purport to represent the future combined financial position or results of operations of Tech Data and the Acquired Business.

The unaudited pro forma condensed combined financial statements do not reflect the impact of any potential cost savings or efficiencies that Tech Data may achieve from the combination of the two entities.

The following unaudited pro forma condensed combined financial statements have been derived from our audited consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended January 31, 2016, our unaudited consolidated financial statements included in our Quarterly Report on Form 10-Q for the fiscal quarter ended October 31, 2016 and the combined financial statements of the Acquired Business filed as Exhibits 99.1 and 99.2 to our Current Report on Form 8-K filed with the SEC on January 17, 2017. The pro forma condensed combined balance sheet and the pro forma condensed combined statement of income as of and for the nine months ended October 31, 2016 and the condensed combined statement of income for the year ended January 31, 2016 have been prepared utilizing period ends for Tech Data and the Acquired Business that differ by fewer than 93 days, as permitted by Regulation S-X.

The historical financial data for the Acquired Business for the year ended January 2, 2016 are derived by adding the financial data from the Acquired Business’ audited combined statements of income for the years ended July 2, 2016 and June 27, 2015, and subtracting the Acquired Business’ unaudited combined statement of income for the six-month periods ended July 2, 2016 and December 27, 2014. The historical financial data for the Acquired Business for the nine-month period ended October 1, 2016 are derived by adding the financial data from the Acquired Business’ audited combined statement of income for the year ended July 2, 2016 and the unaudited condensed combined statement of income for the three-month period ended October 1, 2016, and subtracting the Acquired Business’ unaudited combined statement of income for the six-month period ended January 2, 2016.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Basis of Presentation

The historical financial information has been adjusted to give pro forma effect to events that are (i) directly attributable to the Proposed Acquisition, (ii) factually supportable, and (iii) expected to have a continuing impact on the combined results. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed and have been prepared to illustrate the estimated effect of the Proposed Acquisition and certain other adjustments. The final determination of the purchase price allocation will be based on the fair values of assets acquired and liabilities assumed as of the date the Proposed Acquisition closes, and could result in a significant change to the unaudited pro forma condensed combined financial statements, including goodwill.

Tech Data’s historical results are derived from Tech Data’s audited consolidated statement of income for the year ended January 31, 2016 and unaudited interim consolidated statement of income for the nine months ended October 31, 2016. The historical financial data for the Acquired Business for the year ended January 2, 2016 are derived by adding the financial data from the Acquired Business’ audited combined statements of income for the years ended July 2, 2016 and June 27, 2015, and subtracting the Acquired Business’ unaudited combined statement of income for the six-month periods ended July 2, 2016 and December 27, 2014. The historical financial data for the Acquired Business for the nine-month period ended October 1, 2016 are derived by adding the financial data from the Acquired Business audited combined statement of income for the year ended July 2, 2016 and the unaudited condensed combined statement of income for the three-month period ended October 1, 2016, and subtracting the Acquired Business’ unaudited combined statement of income for the six-month period ended January 2, 2016.

Significant Accounting Policies

The accounting policies used in the preparation of these unaudited pro forma condensed combined financial statements are those set out in Tech Data’s audited financial statements as of January 31, 2016 and the Acquired Business’ audited financial statements as of July 2, 2016. Management has determined that no significant adjustments are necessary to conform the Acquired Business’ financial statements to the accounting policies used by Tech Data in the preparation of these unaudited pro forma condensed combined financial statements. Certain reclassifications have been reflected in the pro forma adjustments, as further described in Note 3, to conform the Acquired Business’ presentation to Tech Data’s in the pro forma balance sheet. The pro forma financial statements may not reflect all adjustments necessary to conform the accounting policies of the Acquired Business to those of Tech Data due to limitations on the availability of information.

Description of the Acquisition

On September 19, 2016, we entered into an Interest Purchase Agreement (the “Acquisition Agreement”) with Avnet to acquire (the “Proposed Acquisition”) all the shares of AVT Technology Solutions LLC (“AVT”) and TS Divestco B.V. (together with AVT, the “Acquired Companies”), which will hold all assets and liabilities primarily relating to the technology solutions business of Avnet (the “Acquired Business”) following completion of the Reorganization (as defined below).

Concurrently with the execution of the Acquisition Agreement, we entered into (i) a Reorganization Agreement (the “Reorganization Agreement”) with Avnet and AVT, pursuant to which Avnet will, prior to the consummation of the Proposed Acquisition, transfer the Acquired Business to the Acquired Companies (the “Reorganization”) and (ii) an Employment Matters Agreement in order to allocate between us and Avnet our respective assets, liabilities and responsibilities with respect to certain employee compensation, pension and benefit plans, programs and arrangements and to provide for certain employment matters in connection with the Proposed Acquisition.

Pursuant to the Acquisition Agreement, and subject to the terms and conditions contained therein, at the closing of the Proposed Acquisition, we will acquire all of the outstanding shares of the Acquired Companies for an aggregate purchase price comprised of $2.4 billion in cash (the “Cash Consideration”) and 2,785,402 shares of our

6

common stock (representing approximately 7.3% of our outstanding common stock after giving effect to the issuance of the new shares), with the Cash Consideration subject to certain working capital and other adjustments, as described in the Acquisition Agreement.

Acquisition Financing

In addition to an offering of senior notes in the aggregate principal amount of $1 billion, we expect to obtain or otherwise incur additional financing for the Proposed Acquisition as described below.

In connection with the Proposed Acquisition, we expect to borrow up to $1 billion under senior unsecured term loan facilities (the “Term Facilities”), consisting of a tranche of three-year senior unsecured term loans in an original aggregate principal amount of $250 million and a tranche of five-year senior unsecured term loans in an original aggregate principal amount of $750 million, and expect to borrow an amount up to $100 million under our $1 billion revolving credit facility (the “Revolving Facility”). We have also obtained commitments for a 30-day senior unsecured bridge loan facility in an original aggregate principal amount of $300 million (the “Cash Bridge Facility”). If, and to the extent the notes in any offering we may conduct to raise permanent financing in the capital markets are not issued and sold (or are issued in a lesser amount), we may borrow up to $1 billion in loans under a 364-day senior unsecured bridge facility (the “Bridge Facility”). We refer to any debt financing that we expect to incur to fund the Cash Consideration and to pay related fees and expenses as the “Debt Financing.”

Tech Data may incur approximately $36 million of transaction costs. This estimate does not include fees related to the debt financing, which are estimated to be approximately $14 million. The fees related to the debt financing were reflected in the unaudited pro forma condensed combined financial statements as debt issuance costs.

2. Calculation of Preliminary Estimated Purchase Price

The fair value of consideration expected to be transferred on the closing date includes the value of the estimated cash consideration, the estimated fair value of the Share Consideration, the estimated working capital adjustment, plus estimated cash, and minus estimated indebtedness. A preliminary estimate of the purchase price is as follows (in thousands, except shares and stock price):

For pro forma purposes only, the fair value of consideration given and thus the estimated purchase price was determined based upon the $86.73 per share closing price of Tech Data’s common stock on January 6, 2017. The final purchase consideration could significantly differ from the amounts presented in the unaudited pro forma condensed combined financial statements due to movements in the Tech Data common stock price as of the closing date of the Proposed Acquisition. A sensitivity analysis related to the fluctuation in the Tech Data common stock price was performed to assess the impact a hypothetical change of 10% on the closing price of Tech Data common stock on January 6, 2017 would have on the estimated purchase price and goodwill as of the closing date.

The following table shows the change in stock price, estimated purchase price and goodwill (dollars in thousands, except stock price):

Preliminary Purchase Price Allocation

Under the acquisition method of accounting, the identifiable assets acquired and liabilities assumed of the Acquired Business are recorded at the acquisition date fair values and added to those of Tech Data. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed as of October 31, 2016 and have been prepared to illustrate the estimated effect of the Proposed Acquisition. The allocation is dependent upon certain valuations and other studies that have not yet been completed. Accordingly, the preliminary purchase price allocation is subject to further adjustment as additional information becomes available and as additional analyses and final valuations are completed. There can be no assurances that these additional analyses and final valuations will not result in significant changes to the estimates of fair value set forth below.

The following table sets forth a preliminary allocation of the estimated purchase price to the identifiable tangible and intangible assets acquired and liabilities assumed of the Acquired Business with the excess recorded as goodwill (dollars in thousands):

Preliminary identifiable intangible assets in the pro forma financial statements consist of anticipated intangibles derived from customer and vendor relationships and trade names. The amortization related to these identifiable intangible assets is reflected as a pro forma adjustment to the pro forma condensed combined statements of income, as further described in Note 5. The identifiable intangible assets and related amortization are preliminary and are based on management’s estimates after consideration of similar transactions. As discussed above, the amount that will ultimately be allocated to identifiable intangible assets, and the related amount of amortization, may differ materially from this preliminary allocation. In addition, the periods the amortization impacts will ultimately be based upon the periods in which the associated economic benefits are expected to be derived, or where appropriate, based on the use of a straight-line method. Therefore, the amount of amortization following the transaction may differ significantly between periods based upon the final value assigned, and amortization methodology used, for each identifiable intangible asset.

Goodwill represents the excess of the preliminary estimated purchase price over the fair value of the underlying net assets. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment. Goodwill recognized in the U.S. from the Proposed Acquisition is expected to be deductible for tax purposes. Goodwill recognized in foreign jurisdictions from the Proposed Acquisition is not expected to be deductible for tax purposes.

8

The final determination of the purchase price allocation upon the closing of the Proposed Acquisition will be based on the Acquired Business’ net assets acquired as of that date and will depend on a number of factors, which cannot be predicted with any certainty at this time. The purchase price allocation may change materially based on the receipt of more detailed information. Therefore, the actual allocations will differ from the pro forma adjustments presented.

The statutory tax rates do not reflect Tech Data’s expected effective tax rate, which will include other tax charges and benefits, and does not take into account any historical or possible future tax events that may impact the combined company.

5. Intangible Assets

The significant intangible assets identified in the preliminary purchase price allocation discussed above include customer and vendor relationships, and trademarks. The table below indicates the estimated fair value of each of the intangibles identified and the approximate useful lives of each (in thousands):

Fair value was estimated using the income approach. The income approach included the use of the multi-period excess earnings method for the acquired customer and vendor relationships and the relief-from-royalty method for the acquired portfolio of trade names. The significant assumptions used in estimating fair value include (i) the estimated life during which the asset will contribute to cash flows, based on inputs such as attrition rate of customers, remaining contractual terms, and expected use of the assets, (ii) the estimated profitability of the operations associated with each of the acquired assets, and (iii) the estimated discount rate that reflects the level of risk associated with receiving future cash flows.

6. Financing Agreements

The Company anticipates new borrowings of approximately $2.1 billion, excluding debt issuance costs, in connection with the Proposed Acquisition, which is comprised of the following:

The unaudited condensed combined pro forma financial statements reflect an estimate of the amount of financing required to complete the Proposed Acquisition. The actual amount of financing required for the Proposed Acquisition will not be determined until the closing date when the actual purchase price and the actual amount of existing cash balances of Tech Data are known. The actual amount of available cash at closing may vary materially from preliminary estimates. The pro forma financial statements also reflect an estimate of interest rates for the various debt facilities based on current market conditions and rates currently available and based on facilities with similar terms and tenors. However, the actual interest incurred may vary significantly based upon, among other things, market considerations, the amount of each debt facility utilized, and success with the note offerings, of various tenors.

Annual future maturities for the five-year senior unsecured term loans are expected to be 5.0% of the initial principal amount each year for the first three years, then increasing to 10% for year four, with the final payment of all remaining outstanding principal amounts, plus accrued interest, being due five years after the closing date. The interest is due quarterly on the five-year senior unsecured term loan. Principal maturities for the three-year senior unsecured term loans and the senior notes are expected to occur at the end of each applicable note term. The interest is due quarterly on the three-year senior unsecured term loan and semi-annually on the senior notes.

A sensitivity analysis on interest expense for the year ended January 31, 2016 and the nine month period ended October 31, 2016 has been performed to assess the effect of a change of 12.5 basis points of the hypothetical interest rate would have on the debt financing.

The following table shows the interest expense assuming a 12.5 basis point change in the interest rates for the debt financing (in thousands):
