Amendment Description	Camping World Holdings, Inc. (the "Company") is filing this Amendment No. 1 to its Quarterly Report on Form 10-Q (this "Amendment") to restate and amend the Company's previously issued condensed consolidated financial statements and related financial information as of and for the three and nine months ended September 30, 2017 and 2016 previously included in its Quarterly Report on Form 10-Q for the quarter ended September 30, 2017 (the "Original Filing"), which was previously filed with the Securities and Exchange Commission (the "SEC") on May 4, 2017 (the "Original Filing Date"). In connection therewith, this Amendment amends and restates in their entirety the following items in the Original Filing: Item 1 of Part I "Financial Statements"; Item 2 of Part I "Management's Discussion and Analysis of Financial Condition and Results of Operations"; and Item 4 of Part I "Controls and Procedures". For the convenience of the reader, this Amendment sets forth the Original Filing, as modified where necessary to reflect the foregoing restatement and revisions. In addition, pursuant to Rule 12b-15 of the Securities Exchange Act of 1934, as amended, Item 6 of Part II of the Original Filing has been amended to contain currently dated certifications from the Company's Chief Executive Officer and Chief Financial Officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, which are attached as Exhibits 31.1, 31.2, 32.1, 32.2 to this Amendment. We have also updated our financial statements formatted in Extensible Business Reporting Language (XBRL) in Exhibits 101. As described in the Company's Current Report on Form 8-K filed March 13, 2018, on March 10, 2018, the Audit Committee of our Board of Directors (the "Audit Committee"), after discussion with Company management and Ernst & Young LLP, our independent registered public accounting firm, determined that the audited consolidated financial statements as of and for the year ended December 31, 2016 included in our Annual Report on Form 10-K for the year ended December 31, 2016 and the unaudited condensed consolidated financial statements as of and for the three and nine months ended September 30, 2017 included in our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2017 previously filed with the SEC should no longer be relied upon and should be amended to reflect the adjustments described herein. Except as described herein, this Amendment does not amend, update or change any other items or disclosures in the Original Filing and does not purport to reflect any information or events subsequent to the Original Filing Date. As such, this Amendment speaks only as of the Original Filing Date, and the Company has not undertaken to amend, supplement or update any information contained in the Original Filing to give effect to any subsequent events. Accordingly, this Amendment should be read in conjunction with the Company's filings made with the SEC subsequent to the filing of the Original Filing, including any amendment to those filings. Background On October 13, 2016, the Company completed an initial public offering of 11,363,636 shares of the Company's Class A common stock at a public offering price of $22.00 per share (the "IPO"). The Company received $233.4 million in proceeds, net of underwriting discounts and commissions, which were used to purchase 11,363,636 newly-issued common units from CWGS Enterprises, LLC ("CWGS, LLC") at a price per unit equal to the initial public offering price per share of Class A common stock in the IPO less underwriting discounts and commissions. In addition, on November 4, 2016, the underwriters exercised their option, in part, to purchase an additional 508,564 shares of Class A common stock. On November 9, 2016, the Company closed on the purchase of the additional 508,564 shares of Class A common stock and received $10.4 million in additional proceeds, net of underwriting discounts and commissions, which were used to purchase 508,564 newly-issued common units from CWGS, LLC at a price per unit equal to the initial public offering price per share of Class A common stock in the IPO less underwriting discounts and commissions. On May 31, 2017, the Company completed a public offering (the "May 2017 Public Offering") in which the Company sold 4,000,000 shares of the Company's Class A common stock at a public offering price of $27.75 per share. The Company received $106.6 million in proceeds, net of underwriting discounts and commissions, which were used to purchase 4,000,000 newly-issued common units from CWGS, LLC at a price per unit equal to the public offering price per share of Class A common stock in the May 2017 Public Offering, less underwriting discounts and commissions. In addition, on June 5, 2017, the underwriters exercised their option to purchase an additional 600,000 shares of Class A common stock. On June 9, 2017, the Company closed on the purchase of the additional 600,000 shares of Class A common stock and received $16.0 million in additional proceeds, net of underwriting discounts and commissions, which were used to purchase 600,000 newly-issued common units from CWGS, LLC at a price per unit equal to the public offering price per share of Class A common stock in the May 2017 Public Offering, less underwriting discounts and commissions. Following the purchase of newly-issued common units from CWGS, LLC as described above, the Company's deferred tax balances have reflected the differences in the book and tax basis of its investment in CWGS, LLC (i.e., outside basis). In connection with preparing its financial statements for the year ended December 31, 2017, the Company determined that a portion of the outside basis deferred tax asset related to its acquisition of the direct interest in CWGS, LLC through newly issued LLC units is not expected to be realized unless the Company were to dispose of its investment in CWGS, LLC, which the Company has no current plan to do. Accordingly, the Company has determined that it should have established a valuation allowance of $102.7 million against this portion of its deferred tax asset that was recorded through equity as of December 31, 2016. Following the establishment of the valuation allowance as of December 31, 2016, the Company recognizes subsequent changes to the valuation allowance through the provision for income taxes or equity, in accordance with generally accepted accounting principles, and at September 30, 2017 the valuation allowance against this portion of its deferred tax asset was $140.8 million. Additional information regarding the impact of the valuation allowance against the portion of the Company's outside basis deferred tax asset related to its acquisition of a direct interest in CWGS, LLC through newly issued LLC units as of December 31, 2016 and September 30, 2017, is contained under the caption "Restatement of Previously Issued Financial Statements" in Note 1 "Summary of Significant Accounting Policies" to our unaudited condensed consolidated financial statements included in this Amendment. Along with restating our financial statements for the correction discussed above, we are making adjustments for certain immaterial items with respect to the three and nine months ended September 30, 2017 and 2016. The Company determined the effect of these corrections was not material to the previously issued financial statements for the years ended December 31, 2016 and 2015, the interim quarterly periods therein or the interim quarterly periods in the year ended December 31, 2017. In conjunction with the restatement described above, we have determined it would be appropriate within this Amendment to record these adjustments for the respective periods. Please refer to the section under the caption "Restatement of Previously Issued Financial Statements" in Note 1 "Summary of Significant Accounting Policies" to our unaudited condensed consolidated financial statements in this Amendment for more information regarding the effect of these adjustments. Restatement of Conclusion Regarding Disclosure Controls and Procedures At the time of the Original Filing, our chief executive officer ("CEO") (principal executive officer) and chief financial officer ("CFO") (principal financial officer) concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of September 30, 2017. Subsequent to that evaluation, our CEO and CFO concluded that our disclosure controls and procedures and internal control over financial reporting were not effective at the reasonable assurance level as of September 30, 2017 because of the material weaknesses in internal control over financial reporting described in Item 4 of Part I "Controls and Procedures" of this Amendment. As a result, we have restated Item 4 of Part I "Controls and Procedures" to reflect the revised conclusion and to include disclosure of the material weaknesses.
