Notes to Unaudited Pro Forma Condensed Combined Financial Information

Note 1: Basis of presentation

The historical consolidated financial statements have been adjusted in the Pro Forma Condensed Combined Financial Statements to give effect to pro forma events that are (1) directly attributable to the business combination, (2) factually supportable and (3) expected to have a continuing impact on the combined results following the business combination. Nonrecurring charges or credits and related tax effects, which result directly from the Transactions and do not have a continuing impact as they will be included in the income of the Company within the 12 months following the Transactions, are not included in the pro forma statements of income.

A Pro Forma Condensed Combined Balance Sheet is not required as the acquisition has already been reflected in the historical balance sheet as of November 26, 2016, included in the Company’s Form 10-Q filed on December 29, 2016.

The business combination was accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. As the acquirer for accounting purposes, the Company has allocated the total purchase price to Grand Design’s tangible and intangible assets acquired and liabilities assumed, based on their fair values at the date of the acquisition.

The Company’s fiscal year ends on the last Saturday of August and Grand Design’s historical fiscal year ends on December 31. To align the periods, the results of Grand Design for the month of September 2016 are included in Unaudited Pro Forma Condensed Combined Statements of Income for both the year ended August 27, 2016 and the three months ended November 26, 2016. The net revenues and net income for Grand Design for the month of September 2016 were $43.0 million and $5.6 million, respectively.

The Pro Forma Condensed Combined Statements of Income do not necessarily reflect what the combined company’s results of operations would have been had the acquisition occurred on the date indicated. They also may not be useful in predicting the future results of operations of the combined company. The actual results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors.

The Unaudited Pro Forma Condensed Combined Statements of Income do not reflect the costs of any integration activities or benefits that may result from realization of future synergies expected to result from the acquisition.

Note 2: Financing transactions

The Company acquired Grand Design for total consideration of approximately $520.6 million on November 8, 2016. For the consideration, the Company issued 4,586,555 of its shares valued at $124.0 million on the closing date and paid cash of $396.6 million. The cash portion of the acquisition was financed by cash and cash equivalents on hand, floating rate borrowings under a term loan of $300.0 million and an asset-based revolving credit agreement (ABL) of $125.0 million, of which $53.0 million was drawn for the acquisition (see note 4(f) below for impact of the financing transactions on pro forma interest expense).

Note 3: Preliminary purchase price allocation

The Company has performed a preliminary valuation analysis of the fair market value of Grand Design’s assets and liabilities. The following table summarizes the allocation of the preliminary purchase price as of the acquisition date:

(In thousands)	November 8, 2016
Cash	$	1,748
Accounts receivable	32,834
Inventories	15,300
Prepaid expenses and other assets	2,161
Property, plant and equipment	8,998
Goodwill	249,981
Other intangible assets	253,100
Total assets acquired	564,122
Accounts payable	11,151
Accrued compensation	3,615
Product warranties	12,904
Promotional	3,976
Other	1,569
Deferred tax liabilities	10,258
Total liabilities assumed	43,473
Total purchase price	$	520,649

This preliminary purchase price allocation has been used to prepare pro forma adjustments in the Pro Forma Condensed Combined Statements of Income. The preliminary purchase price may change based on the final working capital adjustment under the Securities Purchase Agreement. The final purchase price allocation will be determined when the Company has completed all of the detailed valuations and necessary calculations. Thus, the preliminary measures of fair value reflected are subject to changes and such changes could be significant to the Pro Forma Condensed Combined Statements of Income. The final allocation may include (1) changes in allocations to intangible assets and (2) changes to income tax related accounts, as well as changes to other assets and liabilities, which may impact pro forma adjustments to the Pro Forma Condensed Combined Statements of Income.

Note 4: Pro forma adjustments

The pro forma adjustments are based on our preliminary estimates and assumptions that are subject to change. The following adjustments have been reflected in the Unaudited Pro Forma Condensed Combined Statement of Income:

(a) Inventory of finished goods and work in process was increased by $0.3 million for step-up to fair value. This step-up was amortized and increased cost of sales in the three-month period ended November 26, 2016. The $0.3 million of historical amortization from November 8, 2016 through November 26, 2016 has been removed from the Pro Forma Condensed Combined Statement of Income as amortization of the step-up does not have a continuing impact.

(b) Represents the increase in depreciation due to changes in estimated remaining useful lives of Grand Design’s property, plant and equipment due to evaluation in purchase accounting. There was no change in the carrying value of property, plant and equipment, as the Company determined that the historical net carrying value of Grand Design's property, plant and equipment approximated the fair value.

(c) Represents incremental rent expense for two new leases executed in connection with the acquisition of Grand Design. The new leases replaced leases previously in place for the two properties which hold Grand Design’s current principal facilities, and facilities under construction for expansion. The lessor under these leases is an Indiana limited liability company which is owned by three of Grand Design’s selling shareholders.

(d) Represents the removal of transaction costs related to the Grand Design acquisition of $5.5 million for the three-months ended November 26, 2016 and $0.4 million ($355,000 for Winnebago and $57,000 for Grand Design) for the year ended August 27, 2016 since they do not have a continuing impact.

5

(e) As part of the preliminary valuation analysis, the Company identified intangible assets, including trade names, dealer network, backlog, non-compete agreements and favorable leasehold interests. The fair value of identifiable intangible assets is determined primarily using the “income approach,” which requires a forecast of the expected future cash flows. The following table summarizes the preliminary estimated fair values of Grand Design’s identifiable intangible assets and their estimated useful lives and estimated pro forma amortization expense:

				Amortization Expense
(In thousands)	Estimated Fair Value		Estimated Useful Life in  Years	Three Months Ended November 26, 2016			Year Ended August 27, 2016
Trade name	$	148,000	Indefinite	$	—		$	—
Dealer network	80,500		12.0	1,677			6,708
Backlog (1)	18,000		0.5	—			18,000
Non-compete agreements - long-term	4,000		5.0	200			800
Leasehold interest-favorable	2,000		8.1	62			247
Non-compete agreements - short-term (1)	600		1.0	—			600
Total	$	253,100		1,939			26,355
Less: Backlog and non-compete agreements which do not have a continuing impact				—			18,600
Pro forma amortization expense				1,939			7,755
Less: Amortization expense recorded since closing date				2,051			—
Pro forma adjustments to amortization expense				$	(112	)	$	7,755

⁽¹⁾Pro forma amortization expense for the three months ended November 26, 2016 includes no amortization of the backlog and short-term non-compete agreements because the acquisition date assumed for the purposes of pro forma statements is August 30, 2015. Both of these intangible assets have useful lives of one year or less and amortization is complete prior to the three month period presented.

These preliminary estimates of fair value and estimated useful lives may differ from final amounts the Company will calculate after completing a detailed valuation analysis, and the difference could have a significant impact on the accompanying Unaudited Pro Forma Condensed Combined Statements of Income.

(f) Represents the net increase to interest expense resulting from interest on the new term loan and asset-based revolving credit agreement to finance the acquisition of Grand Design and the amortization of related debt issuance costs, as follows:

(In thousands)	Three Months Ended November 26, 2016		Year Ended August 27, 2016
Interest expense on new debt	$	4,406	$	18,003
Amortization of debt issuance costs	394		1,577
Total interest expense	4,800		19,580
Less: Interest expense recorded since closing date	1,128		—
Pro forma adjustments to interest expense	$	3,672	$	19,580

The debt under the term loan and ABL are at variable rates and the interest expense in the table assumes the variable rates of 5.5% and 2.4%, respectively, at November 26, 2016 were constant through the periods presented in the Unaudited Pro Forma Condensed Combined Financial Statements; the revolving credit balance remained constant at $53.0 million; and the principal payments on the term debt were made as scheduled. The variable rate is subject to change. For example, a 1/8% change in term loan and ABL interest rates, would change the interest expense for the three months ended November 26, 2016 and the year ended August 27, 2016 by $0.1 million and $0.5 million, respectively. Additionally, included in interest expense for the periods is a 0.4% commitment fee on the ABL for unused borrowings, which are assumed to be $72.0 million. In addition, non-cash amortization of debt issuance costs is included in interest expense. The expense of $0.1 million for the write-off of fees associated with the existing revolving credit facility being refinanced is not included in the Unaudited Pro Forma Condensed Combined Statements of Income as the write-off is a non-recurring expense.

(g) Reflects the income tax effect on pro forma adjustments and on Grand Design’s historical income based on the estimated blended federal and state statutory tax rate of 37%. Grand Design, as a limited liability company, was an entity that passed-through its taxable income to its owners and accordingly, recorded no tax expense on its statements of income. Therefore, this adjustment includes the estimated tax that Grand Design would have incurred had it not been a pass-through entity. The tax rate does not reflect the 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.

6

(h) Represents the increase in the weighted average shares in connection with the issuance of 4,586,555 common shares to the former owners of Grand Design.

Grand Design had an incentive compensation stock tracking unit (STU) plan whereby fully vested awards were issued to key executives which entitled the holders to receive payments from Grand Design upon the occurrence of an eligible distribution and upon the occurrence of a sale of the business, as defined in the plan. As a return on the STUs was contingent on the occurrence of a future performance condition, no compensation expense was recorded by Grand Design until that event occurred and the amounts were estimable. The acquisition of Grand Design resulted in payments on the closing date to holders of the STUs of $29.8 million. No expense related to this payment is reflected in the net income or the pro forma adjustments for the periods presented in the pro forma information since the payments were fully contingent on the business combination closing, are a non-recurring expense and the plan was terminated at the closing date with no replacement plan adopted. During the twelve months ended September 30, 2016, Grand Design made eligible distributions to STU participants of $1.5 million that were included in general and administrative expense in the year ended September 30, 2016 Grand Design statement of income. No pro forma adjustment has been made to remove this expense as it was not directly related to the Transactions.
