Exhibit 99.3

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

The unaudited pro forma combined financial information (the “pro forma financial information”) combines the historical combined financial statements of Archway Sales, Inc., a Missouri corporation (“Archway”), and JACAAB, LLC, a Missouri limited liability company (“JACAAB”, and together “Archway Sales Group”) and Nexeo Solutions Holdings, LLC (“Holdings” and, together with Nexeo Solutions, LLC (“Solutions”), the “Company”), giving effect to the transaction completed on April 1, 2014, by which Nexeo Solutions Sub Holding Corp. (“Sub Holding”) acquired all issued and outstanding interests in Archway for an aggregate purchase price of approximately $127.0 million, net of cash acquired of $1.6 million (subject to a final estimated net working capital adjustment), which included the purchase by Solutions of substantially all the assets of JACAAB (collectively, the “Archway Acquisition”). Of the purchase price, approximately $15.0 million was placed in escrow. Of this amount, approximately $2.5 million relates to the settlement of the final net working capital adjustment expected no later than 120 days following the close of the transaction. The remaining balance of approximately $12.5 million may remain in escrow for a period of up to two years, relates to certain indemnification obligations under the purchase agreement and will be released as prescribed by the terms of the acquisition documentation. The Archway Acquisition was financed with approximately $10.0 million of cash on hand and approximately $119.0 million of borrowings under the Company’s asset-based revolving credit facility (the “ABL Facility”). The pro forma financial information also includes the effect of the transaction completed on December 2, 2013, by which Sub Holding acquired 100% of the outstanding shares of Chemical Specialists and Development, Inc. (“CSD”), a chemical distribution company and provider of specialty chemicals headquartered in Conroe, Texas, and Solutions acquired substantially all of the assets of STX Freight Company (“STX Freight”) and ST Laboratories Group, LLC (“ST Laboratories”), two related businesses of CSD (the “CSD-Related businesses”). The acquisition of CSD’s outstanding shares and substantially all the assets of STX Freight and ST Laboratories is referred to, collectively, as the “CSD Acquisition.” Please refer to the Current Report on Form 8-K/A (“Amendment No. 1”) filed on February 12, 2014 for the information required by Item 9.01 of Form 8-K related to the CSD Acquisition.

The unaudited pro forma combined statements of operations for the six months ended March 31, 2014 and for the fiscal year ended September 30, 2013 combine the historical combined statements of operations of CSD and the CSD-Related businesses, Archway Sales Group and the historical consolidated statements of operations of the Company, giving effect to the Archway Acquisition and the CSD Acquisition as if they had been consummated on October 1, 2012, the beginning of the Company’s previous fiscal year. The unaudited pro forma combined balance sheet combines the historical combined balance sheet of Archway Sales Group and the historical consolidated balance sheet of the Company as of March 31, 2014, giving effect to the Archway Acquisition as if it had been consummated on March 31, 2014. The historical combined statements of operations of CSD and the CSD-Related businesses and the combined financial statements of Archway Sales Group have been adjusted to reflect certain reclassifications and other adjustments in order to conform to the Company’s financial statement presentation and accounting policies.

The pro forma financial information has been prepared using the acquisition method of accounting in accordance with U.S. generally accepted accounting principles (“US GAAP”) with the Company as the acquirer. Under the acquisition method of accounting, the purchase price is allocated to the underlying tangible and intangible assets acquired and liabilities assumed based on their respective fair market values as of the acquisition date with any excess purchase price allocated to goodwill.

The Company has not completed the detailed valuation studies necessary to arrive at the required estimates of the fair value of the assets acquired, the liabilities assumed and the related allocations of the purchase price in each of the Archway Acquisition and the CSD Acquisition. As a result, the pro forma adjustments are preliminary and are subject to change as additional information becomes available and as additional analyses are performed. The pro forma adjustments have been made solely for the purpose of providing the pro forma financial information presented below. The Company has estimated the fair value of assets acquired and liabilities assumed based on discussions with former members of CSD’s and Archway’s management, preliminary valuation studies, due diligence and information presented in the financial statements and accounting records of CSD, the CSD-Related businesses and Archway Sales Group. The valuations will be finalized as soon as practicable within the required measurement period, but in no event later than one year following completion of the CSD Acquisition and the Archway Acquisition. Any increases or decreases in the fair value of these assets and liabilities upon completion of the final valuations will result in adjustments to the pro forma balance sheet and/or statement of operations. In addition, the final purchase price of the Archway Acquisition is subject to the settlement of the final net working capital adjustment expected no later than 120 days following the close of the transaction.  The final purchase price and the final purchase price allocation may be different than that reflected in the pro forma purchase price allocation presented herein, and this difference may be material.

Assumptions and estimates underlying the unaudited adjustments to the pro forma combined financial information (the “pro forma adjustments”) are described in the accompanying notes. The historical consolidated financial statements have been adjusted in the pro forma combined financial statements to give effect to pro forma events that are: (1) directly attributable to the CSD Acquisition; (2) directly attributable to the Archway Acquisition; (3) factually supportable; and (4) with respect to the pro forma

statement of operations, expected to have a continuing impact on the combined results of the Company following the CSD Acquisition and the Archway Acquisition. The pro forma financial information has been presented for illustrative purposes only and is not necessarily indicative of the operating results and financial position that would have been achieved had these acquisitions occurred on the dates indicated. Further, the pro forma financial information does not purport to project the future operating results or financial position of the Company following the CSD Acquisition and the Archway Acquisition.

The pro forma financial information, although helpful in illustrating the financial characteristics of the Company under one set of assumptions, does not reflect the benefits of expected cost savings (or associated costs to achieve such savings), opportunities to earn additional revenue, or other factors that may result as a consequence of these acquisitions and, accordingly, does not attempt to predict or suggest future results. Specifically, the unaudited pro forma combined statement of operations excludes projected operating efficiencies and synergies expected to be achieved as a result of the CSD Acquisition and the Archway Acquisition. The pro forma financial information also excludes the effects of costs associated with any restructuring activities, integration activities or asset dispositions resulting from the CSD Acquisition and the Archway Acquisition, as they are currently not known, and to the extent they occur, are expected to be non-recurring and were not incurred as of the closing date of the CSD Acquisition or the Archway Acquisition. However, such costs could affect the combined company following the acquisitions in the period the costs are incurred or recorded.

1. Basis of Pro Forma Presentation

Overview

Effective December 1, 2013, Sub Holding acquired 100% of the outstanding shares of CSD, a chemical distribution company and provider of specialty chemicals headquartered in Conroe, Texas, and Solutions acquired substantially all of the assets of STX Freight and ST Laboratories, two related businesses of CSD. The acquisition of CSD’s outstanding shares and substantially all the assets of STX Freight and ST Laboratories is referred to, collectively, as the “CSD Acquisition.” Please refer to Current Report on Form 8-K/A (“Amendment No. 1”) filed on February 12, 2014 for information related to the CSD Acquisition.

Effective April 1, 2014, Sub Holding acquired 100% of the outstanding shares of Archway, a chemical distribution company and provider of specialty chemicals headquartered in St. Louis, Missouri, and Solutions acquired substantially all of the assets of JACAAB, a specialty chemicals manufacturing and repackaging company headquartered in St. Louis, Missouri, for an aggregate purchase price of approximately $126,977 in cash, net of cash acquired of $1,611, of which $14,988 was placed in escrow. Of this amount, $2,488 relates to the settlement of the final net working capital adjustment expected no later than 120 days following the close of the transaction. The remaining balance of $12,500 may remain in escrow for a period of up to two years, and relates to certain indemnification obligations under the purchase agreement and will be released as prescribed under the terms of the acquisition documentation. The acquisition was financed with $10,000 of cash on hand and approximately $119,000 of borrowings under the Company’s ABL Facility.  The Company’s unaudited historical balance sheet as of March 31, 2014 includes the $119,000 of borrowings under Long-term debt and capital lease obligations, less current portion, net.

The pro forma combined statement of operations for the six months ended March 31, 2014 and for the fiscal year ended September 30, 2013 combines the historical consolidated statement of operations of the Company, the historical consolidated statement of operations of CSD and the CSD-Related businesses and the historical combined statement of operations of Archway Sales Group giving effect to the CSD Acquisition and the Archway Acquisition as if they had been consummated on October 1, 2012, the beginning of the Company’s fiscal year. The pro forma combined balance sheet combines the historical consolidated balance sheet of the Company and the historical combined balance sheet of Archway Sales Group as of March 31, 2014, giving effect to the Archway Acquisition as if it had been consummated on March 31, 2014.

The pro forma financial information has been prepared using the acquisition method of accounting under US GAAP. Accordingly, under acquisition accounting, the total purchase price is allocated to the acquired tangible and identifiable intangible assets and liabilities assumed based on their respective fair values, as further described below.

To the extent identified, certain reclassifications and other adjustments have been reflected in the pro forma adjustments to conform the financial statement presentation and accounting policies of the acquired businesses to that of the Company, as described in Note 2. However, the pro forma financial information may not necessarily reflect all adjustments necessary to conform the accounting policies of the acquired businesses to those of the Company due to limitations on the availability of information as of the date of this pro forma financial information.

The pro forma adjustments represent management’s estimates based on information available as of the date of this pro forma financial information and are subject to change as additional information becomes available and additional analyses are performed. The pro forma financial information does not reflect the impact of possible revenue or earnings enhancements, cost savings from operating efficiencies or synergies, or asset dispositions. Also, the pro forma financial information does not reflect possible adjustments related to restructuring or integration activities that have yet to be determined or transaction or other costs following the mergers that are not expected to have a continuing impact. Further, one-time transaction-related expenses incurred prior to, or concurrent with, the closing of the mergers are not included in the pro forma combined statement of operations. However, the impact of such transaction expenses are reflected in the pro forma combined balance sheet as decreases to retained earnings and cash.

Preliminary Purchase Price Allocation — Archway Acquisition

The purchase price for the Archway Acquisition has been allocated to the assets acquired and liabilities assumed for purposes of this pro forma financial information based on their estimated relative fair values. The purchase price allocation herein is preliminary.  The final purchase price allocation for the Archway Acquisition will be determined after completion of a thorough analysis to

determine the fair value of all assets acquired and liabilities assumed but in no event later than one year following completion of the Archway Acquisition. Accordingly, the final acquisition accounting adjustments could differ materially from the pro forma adjustments presented herein. Any increase or decrease in the fair value of the assets acquired and liabilities assumed, as compared to the information shown herein, could also change the portion of purchase price allocable to goodwill and could impact the operating results of the Company following the acquisition due to differences in purchase price allocation, depreciation and amortization related to some of these assets and liabilities.

The purchase price, net of cash acquired of $1,611, was preliminarily allocated as follows:

Preliminary identifiable intangible assets in the pro forma financial information consists of intangibles derived from customer and supplier relationships, non-compete agreements and certain trade names. The amortization related to these amortizable identifiable intangible assets is reflected as a pro forma adjustment to the pro forma combined statement of operations using the straight-line method. Management has determined the estimated remaining useful life of these assets based on its consideration of relevant factors. A five-year remaining useful life for the non-compete agreements has been estimated, based on the contractual term of the agreements with former shareholder and officers of Archway Sales Group. A 10-year remaining useful life for customer and supplier relationships has been estimated based on the projected economic benefits associated with these assets. The 10-year estimated useful life represents the approximate point in the projection period in which a majority of the asset’s cash flows are expected to be realized based on assumed attrition rates.  A two-year remaining useful life for the trade names has been estimated based on the period in which the Company expects a market participant would use the name prior to rebranding and the length of time the name is expected to maintain recognition and value in the marketplace. These assumptions have been developed based on discussions with former members of Archway’s management and Archway’s historical customer and supplier data. The amount that will ultimately be allocated to these assets, and the related amount of amortization, may differ materially from this preliminary allocation.

The purchase price allocation for property, plant and equipment was based on the carrying value of such assets as it was determined to approximate fair value.

Goodwill represents the excess of the total purchase price over the fair value of the underlying net assets, largely arising from synergies expected as a result of the Archway Acquisition. Goodwill is not amortized to earnings, but instead is reviewed for impairment at least annually, absent any indicators of impairment.

Preliminary Purchase Price Allocation — CSD Acquisition

There is no additional impact to the pro forma combined balance sheet as of March 31, 2014 for the CSD Acquisition, as the transaction closed on December 1, 2013 and the Company’s condensed consolidated balance sheet as of March 31, 2014 includes the acquisition of CSD. For information on the preliminary allocation of the CSD Acquisition purchase price, please refer to Note 3 to the Company’s condensed consolidated financial statements as of and for the six months ended March 31, 2014, included in the Company’s quarterly report on Form 10-Q for the six months ended March 31, 2014.
