1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION

Nature of Operations

Duluth Holdings Inc., (“Duluth Trading” or the “Company”) a Wisconsin corporation, is a lifestyle brand of men’s and women’s casual wear, workwear and accessories sold exclusively through the Company’s own direct and retail channels. The direct segment, consisting of the Company’s website and catalogs, offers products nationwide. In 2010, the Company added retail to its omnichannel platform with the opening of its first store. Since then, Duluth Trading has expanded its retail presence, and as of January 31, 2016, the Company operated seven retail stores and two outlet stores across South Dakota, Minnesota, Iowa and Wisconsin. The Company’s products are marketed under the Duluth Trading Company brand, with the majority being exclusively developed and sold as Duluth Trading branded merchandise.

The Company has two classes of authorized common stock: Class A common stock and Class B common stock. The rights of holders of Class A common stock and Class B common stock are identical, except for voting and conversion rights. Each share of Class A common stock is entitled to ten votes per share and is convertible at any time into one share of Class B common stock. Each share of Class B common stock is entitled to one vote per share. The Company’s Class B common stock trades on the NASDAQ Global Select Market under the symbol “DLTH.”

On November 25, 2015, the Company converted from an “S” corporation to a “C” corporation for federal income tax purposes under Section 1362 of the Internal Revenue Code, as amended (the “Code”), and the Company completed its initial public offering (“IPO”). The Company issued and sold 7,666,667 shares of its Class B common stock, which includes 1,000,000 shares of Class B common stock issued pursuant to the underwriters’ option to purchase additional shares, at a price of $12.00 per share, less the underwriting discount. The Company received net proceeds of approximately $83.9 million after deducting the underwriting discount of $6.4 million and related fees and expenses of approximately $1.7 million. The Company used $46.3 million of the net proceeds from the IPO to pay in full the amount previously borrowed from a bank to pay a portion of the distribution of 100% of the cumulative undistributed taxable earnings to its then existing shareholders from the date of its formation through the date of termination of its “S” corporation status.

Basis of Presentation

The consolidated financial statements are prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”). All intercompany balances and transactions have been eliminated.

The Company’s fiscal year ends on the Sunday nearest to January 31 of the following year. Fiscal 2015, 2014 and 2013 ended on January 31, 2016, February 1, 2015 and February 2, 2014, respectively, and were all 52-week periods.

Seasonality of Business

The Company’s business is affected by the pattern of seasonality common to most retail apparel businesses. Historically, the Company has recognized a significant portion of its revenue and operating profit in the fourth fiscal quarter of each year as a result of increased sales during the holiday season.

Unaudited Pro Forma Net Income Information

The unaudited pro forma net income information gives effect to the conversion of the Company to a “C” corporation on November 25, 2015. Prior to such conversion, the Company was an “S” corporation and generally not subject to income taxes. The pro forma net income, therefore, includes an adjustment for income tax expense on the income attributable to controlling interest as if the Company had been a “C” corporation as of February 4, 2013 at an assumed combined federal, state and local effective tax rate of 40%, which approximates the calculated statutory rate for each period. No pro forma income tax expense was calculated on the income attributable to noncontrolling interest because this entity did not convert to a “C” corporation.

The unaudited pro forma basic and diluted net income per share of Class A and Class B common stock is computed using the unaudited pro forma net income, as discussed above.
