CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, any accompanying prospectus and the documents incorporated herein by reference contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Also, documents we subsequently file with the Securities and Exchange Commission, or the SEC, and incorporate by reference will contain forward-looking statements. These statements are subject to risks and uncertainties. All statements other than statements of historical or current fact are forward-looking statements. Forward-looking statements refer to our current expectations and projections relating to our financial condition, results of operations, plans, objectives, strategies, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate”, “estimate”, “expect”, “project”, “plan”, “intend”, “believe”, “may”, “might”, “will”, “should”, “can have”, “likely” and other words and terms of similar meaning in connection with any discussion of the timing or nature of future operating or financial performance or other events. For example, all statements we make relating to our estimated and projected earnings, revenues, comparable store sales, operating income, earnings per share, costs, expenditures, cash flows, growth rates and financial results, our plans and objectives for future operations, growth or initiatives, strategies or the expected outcome or impact of pending or threatened litigation are forward-looking statements. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that we expected, including:

S-iv

S-v

There is no guarantee that any of the events anticipated by the forward-looking statements in this prospectus supplement, any accompanying prospectus and the documents that we incorporate by reference will occur, or if any of the events occur, there is no guarantee what effect it will have on our operations, financial condition or share price. We derive many of our forward-looking statements from our operating budgets and forecasts, which are based upon detailed assumptions. While we believe that our assumptions are reasonable, we caution that it is very difficult to predict the impact of known factors, and it is impossible for us to anticipate all factors that could affect our actual results. Our past performance, and past or present economic conditions in the retail market, are not indicative of future performance or conditions. Investors are urged not to place undue reliance on forward-looking statements. We will not, and undertake no obligation to, update or revise forward-looking statements to reflect changed assumptions, the occurrence of anticipated or unanticipated events or changes to projections over time unless required by federal securities laws.

See “Risk Factors,” as well as those factors or conditions described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in each case in our annual report on Form 10-K for the year ended February 3, 2018, in our quarterly reports on Form 10-Q for the quarters ended May 5, 2018 and August 4, 2018, and in any other filings with the SEC incorporated by reference in this prospectus supplement for a more complete discussion of the risks and uncertainties mentioned above and for discussion of other risks and uncertainties. All forward-looking statements attributable to us are expressly qualified in their entirety by these cautionary statements as well as others made in this prospectus supplement, the accompanying prospectus and the documents incorporated herein, and hereafter in our other SEC filings and public communications. You should evaluate all forward-looking statements made by us in the context of these risks and uncertainties.

We caution you that the risks and uncertainties identified by us may not be all of the factors that are important to you. Furthermore, the forward-looking statements included in this prospectus supplement and the accompanying prospectus are made only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.

inconsistent merchandising offerings, and, as a result, we experienced declines in in-store traffic, sales and operating margins. Beginning in 2015, under the leadership of Edmond Thomas, who rejoined Tillys in October 2015 with over 30 years of retail experience, including serving as President and Co-Chief Executive Officer of Tillys from October 2005 to October 2007, we focused on slowing new store growth, and improving the merchandising selection and inventory management across the fleet to stabilize sales and improve profitability. Under Mr. Thomas’ leadership, we implemented several strategic initiatives, including taking a more conservative and strategic approach to new store growth and closing selected stores, as well as executing various merchandising initiatives within our stores and on our website to improve sales performance. Through these initiatives, we delivered seven consecutive quarters of year-over-year store traffic growth, flat to positive comparable store net sales for nine consecutive quarters, consistently healthy product margins and improved year-over-year operating margins for fiscal 2016, 2017 and the first half of fiscal 2018.

We believe, as we continue to execute on our core strategies, that we can continue to grow sales and improve profitability through positive comparable store sales, driven by increased traffic and e-commerce sales growth, as well as approaching store growth in a disciplined manner and effectively leveraging fixed costs. Our goal is to open new stores in attractive markets with strong economics in order to drive profitability in the first year. We plan to open approximately 12 new full-size stores during fiscal 2018, five of which have already opened. Our RSQ pop-up stores also provide short-term options for us to test new markets and increase our brand awareness.

We believe our customer-focused strategy and experienced, passionate team have placed the Company in a strong market position with meaningful room for future growth. Recent financial highlights include:

 

Net Sales ($mm)		Comparable Store Sales (%)
Operating Income (Loss) ($mm) & Operating Margin (%) (1)(2)		Net Income (Loss) ($mm) (2)

 

(1)	Operating margin represents operating income (loss) as a percentage of net sales for the corresponding period.

(2)

Operating income (loss), operating margin and net income (loss) for fiscal 2017 and the first half of fiscal 2017 were impacted by a non-recurrent $6.2 million provision related to a legal settlement. Operating income (loss), operating margin and net income (loss) for the first half of fiscal 2018 were impacted by a non-recurrent credit of $1.5 million against such provision as a result of the final settlement of such legal matter in early August 2018.

Our Strengths

We believe that the following competitive strengths contribute to our success and distinguish us from our competitors:

 

•

Destination retailer with a unique store experience and a broad and differentiated assortment. We believe the combined depth and breadth of apparel, footwear and accessories offered at our stores exceeds the selection offered at many other specialty retailers. We offer an extensive selection of over 400 third-party lifestyle brands over the course of a given year, which are complemented by our proprietary brands. Our merchandise includes a wide assortment of brands, styles, colors, sizes and price points to ensure we have what our customers want every time they visit our stores. We offer a balanced mix of merchandise across the apparel, footwear and accessories categories serving young adults, teens and children. We believe that by combining proven and emerging fashion trends and core style products with a vibrant blend of carefully selected music and visuals, we provide an in-store experience that is authentic, fun, and engaging for our core customers. Having a diverse assortment of brands and merchandise ensures that we are not overly dependent on any one brand or trend at any point in time. We also believe that our differentiated in-store environment, evolving selection of relevant brands, and broad and deep assortment encourages customers to visit our stores more frequently and positions us as a leading destination retailer that appeals to a large demographic.

For fiscal 2017.

 

•

Dynamic merchandise model. We believe our extensive selection of third-party and proprietary merchandise allows us to identify and offer several trends simultaneously, offer a broad range of price points, and manage our inventories more dynamically. By closely monitoring trends and shipping product to our stores multiple times per week, we are able to adjust our merchandise mix based on store size and location. Different trends are applicable to different geographies, requiring us to analyze and adjust to what trends are best suited for each store. We believe our dynamic merchandise model allows us to do this efficiently, helping us to stay relevant to all of our customers across the country. We also keep our merchandise mix relevant by introducing emerging brands not available at many other retailers. We believe a significant percentage of our apparel offerings are unique to us due to the mix of our proprietary brands, emerging brands not offered at many other retailers, and special make-ups from popular brands that are not offered elsewhere or are offered only on a limited basis. Our merchandising capabilities also enable us to adjust our merchandise mix with a frequency that promotes a current look to our stores and website, and encourages frequent visits.

 

•

Flexible real estate strategy across real estate venues and geographies. Our stores have generally proven to be successful in different real estate venues and geographies. We operate stores in malls,

RISK FACTORS

Investment in the Class A common stock offered pursuant to this offering involves risks. You should carefully consider the following risk factors, as well as the other information in this prospectus supplement and the accompanying prospectus, including the information incorporated by reference, before making an investment decision. In addition, you should carefully consider, among other things, the matters discussed under “Part I—Item 1A. Risk Factors” in our annual report on Form 10-K for the fiscal year ended February 3, 2018, which is incorporated by reference in this prospectus supplement and the accompanying prospectus, as that disclosure may be updated by subsequent periodic reports, as well as other documents that we file with the SEC that are incorporated by reference.

The risks and uncertainties described in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein are not the only ones facing us. Additional risks and uncertainties that we do not presently know about or that we currently believe are not material may also adversely affect our business. If any of the risks and uncertainties described in this prospectus supplement, the accompanying prospectus or the documents incorporated by reference herein and therein actually occur, our business, financial condition and results of operations could be adversely affected in a material way. This could cause the price of our Class A common stock to decline, perhaps significantly.

Risks Related to Our Class A Common Stock and this Offering

Our founders control a majority of the voting power of our common stock, which may prevent other stockholders from influencing corporate decisions and may result in perceived conflicts of interest.

Our common stock consists of two classes: Class A and Class B. Holders of Class A common stock are entitled to one vote per share, and holders of Class B common stock are entitled to 10 votes per share, on all matters to be voted on by our common stockholders. All of the shares of Class B common stock are beneficially owned by Hezy Shaked, Tilly Levine and their children through related trusts, which we refer to as the Shaked and Levine family entities. As a result, the Shaked and Levine family entities control a substantial majority of the total voting power of our outstanding common stock. As of August 31, 2018, the Shaked and Levine family controlled approximately 90.0% of the voting power of our outstanding common stock. After giving pro forma effect to the completion of this offering, the Shaked and Levine family entities would control approximately 72.6% of the voting power of our outstanding common stock (or 67.0% of the voting power of our outstanding common stock if the underwriters exercise their option to purchase additional shares of Class A common stock in full). In addition, Mr. Shaked serves as Executive Chairman of the Board of Directors, and is the voting trustee, pursuant to a voting trust agreement, covering the shares owned by Ms. Levine. As a result, Mr. Shaked is in a position to dictate the outcome of any corporate actions requiring stockholder approval, including the election of directors and mergers, acquisitions and other significant corporate transactions. Mr. Shaked may delay or prevent a change of control from occurring, even if the change of control could appear to benefit the stockholders. Mr. Shaked may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. This ownership concentration may adversely impact the trading of our Class A common stock because of a perceived conflict of interest that may exist, thereby depressing the value of our Class A common stock.

Future sales of our common stock by us or by existing stockholders could cause the price of our Class A common stock to decline.

Any sales of a substantial number of shares of our common stock in the public market, or the perception that such sales might occur, may cause the market price for our Class A common stock to decline. All of our shares of common stock are freely tradable without restriction under the Securities Act of 1933, as amended, or Securities Act, other than the shares of Class A common stock and Class B common stock held by the Shaked and Levine family entities, and the shares of Class A common stock held by our directors, officers and other

S-11

affiliates. Even those shares held by affiliates may be sold under Rule 144 of the Securities Act, subject to the volume and manner of sale, and other requirements thereunder, or pursuant other potential exemptions. In addition, investors may incur dilution upon the exercise of stock options or other equity-based awards under our equity incentive plans. We also may issue equity securities in the future, which would dilute the ownership interest of the holders of our Class A common stock. We cannot predict the size of any future issuances of our common stock or other equity-related securities or the effect, if any, that they may have on the market price of our Class A common stock.

While we paid dividends in February of 2018 and 2017, there can be no assurance that we will pay dividends in the future, which may make our Class A common stock less desirable to investors and decrease its value.

In February of 2018 and 2017, we paid special cash dividends of $1.00 per share and $0.70 per share, respectively, to all holders of record of issued and outstanding shares of our common stock. However, there can be no assurance that we will pay additional cash dividends on our common stock in the future. We do not currently anticipate declaring any additional dividends in the foreseeable future. The declaration and payment of future dividends, if any, will be at the sole discretion of our board of directors based on its consideration of various factors, including our operating results, financial condition, and anticipated capital requirements. As a result, if no dividends are declared in the future, our Class A common stock may be deemed to be less desirable to investors and may decrease in value.

We are a controlled company within the meaning of the NYSE rules, and, as a result, we may rely on exemptions from certain corporate governance requirements that provide protection to stockholders of other companies.

Mr. Shaked controls, and after giving pro forma effect to the completion of this offering (including if the underwriters exercise their option to purchase additional shares of Class A common stock in full), would continue to control, more than 50% of the total voting power of our common stock and we are considered a controlled company under the NYSE corporate governance listing standards. As a controlled company, certain exemptions under the NYSE listing standards will exempt us from the obligation to comply with certain NYSE corporate governance requirements, including the requirements:

Although we intend to continue to comply with these listing requirements even though we are a controlled company, there is no guarantee that we will not take advantage of these exemptions in the future. Accordingly, so long as we are a controlled company, holders of our Class A common stock may not have the same protections afforded to stockholders of companies that are subject to all of the NYSE corporate governance requirements.

S-12

Our amended and restated bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or other employees.

Our amended and restated bylaws provide that, unless we consent in writing to an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, or (iv) any action asserting a claim that is governed by the internal affairs doctrine. Any person purchasing or otherwise acquiring any interest in any shares of our capital stock shall be deemed to have notice of and to have consented to this provision of our amended and restated bylaws. This choice-of-forum provision may limit our stockholders’ ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage such lawsuits. Alternatively, if a court were to find this provision of our amended and restated bylaws inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business and financial condition.

The price of our Class A common stock has been, and may continue to be volatile and may decline in value.

The market for retail apparel stocks can be highly volatile. As a result, the market price of our Class A common stock is likely to be volatile and investors may experience a decrease in the value of the Class A common stock, unrelated to our operations. The price of our Class A common stock has, and could in the future, fluctuate significantly in response to a number of factors, as discussed in this “Risk Factors” section. Further, securities class action litigation has often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources, and could also require us to make substantial payments to satisfy judgments or to settle litigation. The threat or filing of class action litigation lawsuits could cause the price of our Class A common stock to decline.

As a result of being a publicly traded company, our management is required to devote substantial time to complying with public company regulations.

As a result of being a publicly traded company, we are obligated to file periodic reports with the SEC under the Exchange Act. We are also subject to other reporting and corporate governance requirements, including certain requirements of the NYSE, Financial Industry Regulatory Authority, or FINRA, and certain provisions of the Sarbanes-Oxley Act of 2002, or SOX, and the regulations promulgated thereunder, which impose significant compliance obligations on us. SOX, as well as rules subsequently implemented by the SEC, NYSE and FINRA, have imposed increased regulation and disclosure and have required enhanced corporate governance practices of public companies. Our efforts to comply with evolving laws, regulations and standards result in increased administrative expenses and a diversion of management’s time and attention from revenue-generating activities. In addition, if we fail to implement or maintain the requirements with respect to our internal accounting and audit functions, our ability to continue to report our operating results on a timely and accurate basis could be impaired and we could be subject to sanctions or investigation by regulatory authorities, such as the SEC, NYSE or FINRA. Any such action could harm our reputation and the confidence of investors and customers in our company and could materially adversely affect our business and cause the price of our Class A common stock to decline.

S-13

Our failure to maintain adequate internal controls over our financial and management systems may cause errors in our financial reporting, which could in turn cause a loss of investor confidence.

Our public company reporting obligations and our anticipated growth will likely strain our financial and management systems, internal controls and our employees. In addition, pursuant to Section 404 of SOX, we are required to provide annually an assessment of the effectiveness of our internal controls over financial reporting and our independent registered public accounting firm will be required to provide an attestation on our assessment of our internal controls over financial reporting. The process required to comply with Section 404 of SOX is time consuming and costly. If during this process we identify one or more material weaknesses in our internal controls, it is possible that our management may not be able to certify that our internal controls are effective by the certification deadline. Moreover, if we identify any material weaknesses or significant deficiencies in our internal controls we will have to implement appropriate changes to these controls, which may require specific compliance training for our directors, officers and employees, require the hiring of additional finance, accounting, legal and other personnel, entail substantial costs to modify our existing accounting systems and take a significant period of time to complete. Such changes may not, however, be effective in maintaining the adequacy of our internal controls, and any failure to maintain that adequacy, or consequent inability to produce accurate financial statements on a timely basis, could increase our operating costs and could materially impair our ability to operate our business. Effective internal controls are necessary for us to produce reliable financial reports and are important to prevent fraud. As a result, our failure to satisfy the requirements of Section 404 on a timely basis could result in us being subject to regulatory action and a loss of investor confidence in the reliability of our financial statements, both of which in turn could cause the market value of our Class A common stock to decline.

Our corporate organizational documents and Delaware law have anti-takeover provisions that may inhibit or prohibit a takeover of us and the replacement or removal of our management.

In addition to the concentration of ownership and voting power in the Shaked and Levine family entities, the anti-takeover provisions under Delaware law, as well as the provisions contained in our corporate organizational documents, may make an acquisition of us more difficult. For example:

S-14

These provisions may prevent a merger or acquisition of us which could limit the price investors would pay for our common stock in the future.

If securities or industry analysts publish inaccurate or unfavorable research about our business, the price and trading volume of our Class A common stock could decline.

The trading market for our Class A common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who covers us downgrades our Class A common stock or publishes inaccurate or unfavorable research about our business, the price of our Class A common stock would likely decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our Class A common stock could decrease, which could cause the price of our Class A common stock and trading volume to decline.

Financial forecasting by us and financial analysts who may publish estimates of our performance may differ materially from actual results.

Given the dynamic nature of our business, the current uncertain economic climate and the inherent limitations in predicting the future, forecasts of our revenues, comparable sales, margins, net income and other financial and operating forecasts may differ materially from actual results. Such discrepancies could cause a decline in the trading price of our Class A common stock.

We have a small public float and this may result in price swings in our Class A common stock or make it difficult to acquire or dispose of our Class A common stock.

We have a small public float, and will continue to have a small public float following the consummation of this offering. A small public float can result in large swings in the stock price of our Class A common stock with relatively low trading volume. In addition, a purchaser that seeks to acquire a significant number of shares of Class A common stock may be unable to do so without increasing the stock price of our Class A common stock, and conversely, a seller that seeks to dispose of a significant number of shares of our Class A common stock may experience a decreasing stock price.

Risks Related to Our Business and Our Industry

For risks related to our business and our industry, see the information under the headings “Risk Factors”, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Business” in our annual report on Form 10-K for the fiscal year ended February 3, 2018 and any subsequent periodic reports filed by us with the SEC.

USE OF PROCEEDS

All of the Class A common stock offered by this prospectus supplement is being sold by the Selling Stockholders.

PRICE RANGE OF OUR CLASS A COMMON STOCK

Since May 4, 2012, our Class A common stock has traded on the NYSE under the symbol “TLYS.” The following table sets forth, for the periods indicated, the high and low daily sales prices for our Class A common stock, as reported by the NYSE.

On August 31, 2018, the last reported sale price for our Class A common stock on the NYSE was $23.52 per share. As of August 31, 2018, we had 15,660,185 shares of Class A common stock outstanding and there were approximately 7 holders of record of our Class A common stock, including shares of unvested restricted stock awards.

SELLING STOCKHOLDERS

The following table sets forth (i) the number of shares of Class A common stock and Class B common stock beneficially owned by the Selling Stockholders as of the date of this prospectus supplement, (ii) the number of shares of Class A common stock to be offered by each of the Selling Stockholders pursuant to this offering, assuming no exercise by the underwriters of their option to purchase up to an additional 1,215,000 shares of our Class A common stock from the Selling Stockholders, and (iii) the number of shares of Class A common stock and Class B common stock beneficially owned by the Selling Stockholders, as adjusted to reflect the assumed sale of all 8,100,000 shares offered pursuant this offering, assuming no exercise by the underwriters of their option to purchase up to an additional 1,215,000 shares of our Class A common stock from the Selling Stockholders.

UNDERWRITING

Merrill Lynch, Pierce, Fenner & Smith Incorporated is acting as the representative of each of the underwriters named below. Subject to the terms and conditions set forth in an underwriting agreement among us, the Selling Stockholders and the underwriters, the Selling Stockholders have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from the Selling Stockholders, the number of shares of our Class A common stock set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the shares sold under the underwriting agreement if any of these shares are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

We and the Selling Stockholders have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Commissions and Discounts

The representative has advised us and the Selling Stockholders that the underwriters propose initially to offer the shares to the public at the public offering price set forth on the cover page of this prospectus supplement and to dealers at that price less a concession not in excess of $            per share. After the initial offering, the public offering price, concession or any other term of the offering may be changed.

The following table shows the public offering price, underwriting discount and proceeds before expenses to the Selling Stockholders. The information assumes either no exercise or full exercise by the underwriters of their option to purchase additional shares.

The expenses of the offering, not including the underwriting discount, are estimated at $500,000 and are payable by us. We have agreed to reimburse the underwriters for certain fees and expenses in connection with this offering, up to an amount not to exceed $35,000.

S-20

Option to Purchase Additional Shares

The Selling Stockholders have granted an option to the underwriters, exercisable for 30 days after the date of this prospectus supplement, to purchase up to 1,215,000 additional shares of our Class A common stock at the public offering price, less the underwriting discount. If the underwriters exercise this option, each will be obligated, subject to conditions contained in the underwriting agreement, to purchase a number of additional shares of our Class A common stock proportionate to that underwriter’s initial amount reflected in the above table.

No Sales of Similar Securities

We and the Selling Stockholders, our executive officers and directors have agreed not to sell or transfer any shares of our Class A common stock or securities convertible into, exchangeable for, exercisable for, or repayable with our Class A common stock, including, without limitation, any shares of our Class B common stock, for 90 days after the date of this prospectus supplement without first obtaining the written consent of Merrill Lynch, Pierce, Fenner & Smith Incorporated. Specifically, we and these other persons have agreed, with certain limited exceptions, not to directly or indirectly

This lock-up provision applies to common stock and to securities convertible into or exchangeable or exercisable for or repayable with common stock. It also applies to common stock owned now or acquired later by the person executing the agreement or for which the person executing the agreement later acquires the power of disposition. In addition, the lock-up agreement will not prohibit:

New York Stock Exchange Listing

The shares of our Class A common stock are listed on the New York Stock Exchange under the symbol “TLYS.”

S-21

Price Stabilization, Short Positions

Until the distribution of the shares is completed, SEC rules may limit underwriters and selling group members from bidding for and purchasing our common stock. However, the representative may engage in transactions that stabilize the price of the common stock, such as bids or purchases to peg, fix or maintain that price.

In connection with the offering, the underwriters may purchase and sell our common stock in the open market. These transactions may include short sales, purchases on the open market to cover positions created by short sales and stabilizing transactions. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in the offering. “Covered” short sales are sales made in an amount not greater than the underwriters’ option to purchase additional shares described above. The underwriters may close out any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to close out the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the option granted to them. “Naked” short sales are sales in excess of such option. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of our common stock in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of various bids for or purchases of shares of common stock made by the underwriters in the open market prior to the completion of the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of our common stock or preventing or retarding a decline in the market price of our common stock. As a result, the price of our common stock may be higher than the price that might otherwise exist in the open market. The underwriters may conduct these transactions on the NYSE, in the over-the-counter market or otherwise.

Neither we nor any of the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of our common stock. In addition, neither we nor any of the underwriters make any representation that the representative will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Electronic Distribution

In connection with the offering, certain of the underwriters or securities dealers may distribute prospectuses by electronic means, such as e-mail.

Other Relationships

Some of the underwriters and their affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriters and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

European Economic Area

In relation to each member state of the European Economic Area, no offer of shares which are the subject of the offering has been, or will be made to the public in that Member State, other than under the following exemptions under the Prospectus Directive:

provided that no such offer of shares referred to in (a) to (c) above shall result in a requirement for the company or the representative to publish a prospectus pursuant to Article 3 of the Prospectus Directive, or supplement a prospectus pursuant to Article 16 of the Prospectus Directive.

Each person located in a Member State to whom any offer of shares is made or who receives any communication in respect of an offer of shares, or who initially acquires any shares will be deemed to have represented, warranted, acknowledged and agreed to and with the Representative and the Company that (1) it is a “qualified investor” within the meaning of the law in that Member State implementing Article 2(1)(e) of the Prospectus Directive; and (2) in the case of any shares acquired by it as a financial intermediary as that term is used in Article 3(2) of the Prospectus Directive, the shares acquired by it in the offer have not been acquired on behalf of, nor have they been acquired with a view to their offer or resale to, persons in any Member State other than qualified investors, as that term is defined in the Prospectus Directive, or in circumstances in which the prior consent of the Representative has been given to the offer or resale; or where shares have been acquired by it on behalf of persons in any Member State other than qualified investors, the offer of those shares to it is not treated under the Prospectus Directive as having been made to such persons.

The company, the representative and their respective affiliates will rely upon the truth and accuracy of the foregoing representations, acknowledgments and agreements.

This prospectus supplement has been prepared on the basis that any offer of shares in any Member State will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of shares. Accordingly any person making or intending to make an offer in that Member State of shares which are the subject of the offering contemplated in this prospectus supplement may only do so in circumstances in which no obligation arises for the company or the representative to publish a prospectus pursuant to Article 3 of the Prospectus Directive in relation to such offer. Neither the company nor the representative has authorized, nor do they authorize, the making of any offer of shares in circumstances in which an obligation arises for the company or the representative to publish a prospectus for such offer.

For the purposes of this provision, the expression an “offer of shares to the public” in relation to any shares in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the shares to be offered so as to enable an investor to decide to purchase or subscribe the shares, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (as amended) and includes any relevant implementing measure in each Member State.

The above selling restriction is in addition to any other selling restrictions set out below.

USE OF PROCEEDS

We will not receive any proceeds from the sale of shares of Class A common stock by any of the Selling Stockholders.

DESCRIPTION OF CAPITAL STOCK

The following description of our capital stock is not complete and may not contain all the information you should consider before investing in our capital stock. This description is summarized from, and qualified in its entirety by reference to, our certificate of incorporation and bylaws, which have been publicly filed with the SEC. See “Where You Can Find More Information; Incorporation by Reference.”

Our authorized capital stock consists of:

Common Stock

Our certificate of incorporation divides our common stock into two classes of common stock, Class A common stock and Class B common stock. Holders of Class A common stock and Class B common stock have identical rights, except with respect to certain voting and conversion as further described below. The holders of Class A common stock are entitled to one vote per share held of record and holders of Class B common stock are entitled to 10 votes per share held of record on all matters submitted to a vote of stockholders, including the election of directors. Except as may be provided with respect to shares of preferred stock, the holders of our common stock will possess the exclusive voting power.

Holders of our common stock will have no preference, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of our securities.

Voting Rights.

On all matters on which the holders of our common stock are entitled to vote, the holders of the Class A common stock and the Class B common stock vote together as a single class. Holders of Class A common stock are entitled to one vote for each share held of record and holders of Class B common stock are entitled to 10 votes for each share held of record on all matters submitted to a vote of stockholders. Holders of our common stock will not have cumulative voting rights, which means that in the election of directors, the holders of shares of common stock representing a plurality of the votes cast can elect all of the directors then standing for election, and the holders of the remaining shares will not be able to elect any directors. Our stockholders cannot amend, alter or repeal any provision of our bylaws without the affirmative vote of two thirds of all stockholders voting together as a single class.

Conversion of Class B Common Stock.

All outstanding shares of Class B common stock will convert automatically into a like number of shares of Class A common stock in the event:

11

In addition, shares of Class B common stock that are transferred will automatically convert into a like number of shares of Class A common stock, other than transfers to Hezy Shaked or a Hezy Shaked Entity.

For purposes of our certificate of incorporation, a “Hezy Shaked Entity” is:

Dividend Rights.

The holders of our common stock are entitled to receive pro rata such lawful dividends when, if and as may be declared from time to time by our board of directors out of funds legally available for payment. However, such dividends would be subject to preferences that may be applicable to the holders of any outstanding shares of our preferred stock. See “Dividend Policy.”

Liquidation.

In the event of a liquidation, dissolution or winding up of the affairs of our company, whether voluntary or involuntary, the holders of our common stock will be entitled to receive pro rata all of our remaining assets available for distribution to our stockholders. Any such pro rata distribution would be subject to the rights of the holders of any outstanding shares of our preferred stock.

Rights and Preferences.

The shares of our common stock have no preemptive rights, no redemption or sinking fund provisions and are not liable for further call or assessment. The rights, powers, preferences and privileges of holders of our common stock are subject to, and may be adversely affected by, the rights of the holders of shares of any series of our preferred stock that we may designate and issue in the future. The outstanding shares of our common stock are, and all shares of common stock to be issued in this offering will be, non-assessable.

Transfer Agent

The transfer agent and registrar for our common stock is Continental Stock Transfer & Trust Company.

12

Dividend Policy

Our Class A common stock began trading on the New York Stock Exchange on May 4, 2012, in connection with our initial public offering. On January 31, 2017, we declared our first-ever special cash dividend of $0.70 per share to all holders of record of issued and outstanding shares of both Class A common stock and Class B common stock as of the close of business on February 15, 2017, with payment made on February 24, 2017. On January 24, 2018, we declared a special cash dividend of $1.00 per share to all holders of record of issued and outstanding shares of both Class A common stock and Class B common stock as of the close of business on February 9, 2018, with payment made on February 20, 2018. There can be no assurance that future dividends will be paid by us. We do not currently anticipate declaring any additional dividends in the foreseeable future. The declaration and payment of future dividends, if any, will be at the sole discretion of our board of directors based on its consideration of various factors, including our operating results, financial condition, and anticipated capital requirements.

Preferred Stock

As of July 16, 2018, we had no shares of preferred stock outstanding. Our board of directors has the authority, without further action by the stockholders, to issue up to 10,000,000 shares of preferred stock in one or more series and to fix the designations, powers, preferences, privileges, and relative participating, optional, or special rights as well as the qualifications, limitations, or restrictions of the preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights of the common stock. Accordingly, our board of directors, without stockholder approval, may issue preferred stock with voting, conversion, or other rights that could adversely affect the voting power and other rights of the holders of common stock. Preferred stock could be issued quickly with terms calculated to delay or prevent a change of control or make removal of management more difficult. Additionally, the issuance of preferred stock may have the effect of decreasing the market price of our Class A common stock, may adversely affect the voting and other rights of the holders of our common stock, and could have the effect of delaying, deferring or preventing a change of control of our company or other corporate action. At present, we have no plans to issue any shares of preferred stock.

Anti-Takeover Effects of Delaware Law

We are subject to the provisions of Section 203 of the Delaware General Corporation Law. Under Section 203, we would generally be prohibited from engaging in any business combination with any interested stockholder for a period of three years following the time that this stockholder became an interested stockholder unless:

13

Under Section 203, a “business combination” includes:

In general, Section 203 defines an interested stockholder as an entity or person beneficially owning 15% or more of the outstanding voting stock of the corporation and any entity or person affiliated with or controlling or controlled by such entity or person.

14

SELLING STOCKHOLDERS

This prospectus relates to the possible resale by the Selling Stockholders, of up to 9,500,000 shares of our Class A common stock, which represents the maximum number of shares of Class A common stock issuable upon conversion of 8,859,389 shares of Class B common stock held by certain of the Selling Stockholders at a conversion rate of one share of Class A common stock for each share of Class B common stock, in addition to 540,611 shares of Class A common stock held by Reid Investments LLC, and 100,000 shares of Class A common stock underlying stock options granted to Hezy Shaked that have vested and are exercisable.

On May 2, 2012, in connection with the initial public offering of the Company, Hezy Shaked, Tilly Levine and certain trusts for which immediate family members of Mr. Shaked and Ms. Levine were trustees and the beneficiaries, exchanged all of their equity interests in World of Jeans & Tops for shares of Tilly’s, Inc. Class B common stock on a one-for-one basis. On September 2, 2014, the trusts that held such shares of Class B common stock terminated by their respective terms, and, in accordance with their terms, distributed for no consideration their respective Class B common stock to the remaining Selling Stockholders described below.

The following table sets forth information with respect to the beneficial ownership of our common stock held as of July 16, 2018 by each of the Selling Stockholders, including the number of shares of Class A common stock being offered hereby and information with respect to common stock to be beneficially owned by the Selling Stockholders assuming all the shares of Class A common stock registered hereunder are sold. Beneficial ownership is determined in accordance with the rules of the SEC. Except as indicated by footnote, we believe that each stockholder identified in the table possesses sole voting and investment power with respect to the shares shown as beneficially owned by such stockholder.

The information set forth in the table below is based on information provided by or on behalf of the Selling Stockholders. Information concerning the Selling Stockholders may change from time to time and any changed information will be set forth in supplements to this prospectus, if and when necessary. The Selling Stockholders may offer all, some or none of their shares of Class A common stock to the extent permitted by the rules of the SEC. We cannot advise you as to whether the Selling Stockholders will in fact sell any or all of such shares of Class A common stock. In addition, the Selling Stockholders listed in the table below may have sold, transferred or otherwise disposed of all or a portion of their Class A common stock since the date on which they provided the information set forth in the table below. The address of each of the Selling Stockholders named in the table below is: c/o Tilly’s, Inc., 10 Whatney, Irvine, California, 92618.

PLAN OF DISTRIBUTION

Any of the Selling Stockholders may sell some or all of the Class A common stock covered by this prospectus from time to time pursuant to underwritten public offerings, negotiated transactions, block trades or a combination of these methods or through underwriters or dealers, through agents and/or directly to one or more purchasers. To the extent required, this prospectus and any free writing prospectus may be amended and supplemented from time to time to describe a specific plan of distribution. The Class A common stock may be distributed from time to time in one or more transactions:

The Selling Stockholders may decide not to sell the Class A common stock described in this prospectus. We cannot assure holders that any Selling Stockholder will use this prospectus to sell any or all of the Class A common stock. Any securities covered by this prospectus that qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus. In addition, a Selling Stockholder may transfer, devise or gift the Class A common stock by other means not described in this prospectus.

Offers to purchase the Class A common stock being offered by this prospectus may be solicited directly. Agents may also be designated to solicit offers to purchase the Class A common stock from time to time. Any agent involved in the offer or sale of the Class A common stock will be identified in a prospectus supplement.

If a dealer is utilized in the sale of the Class A common stock being offered by this prospectus, the Class A common stock will be sold to the dealer, as principal. The dealer may then resell the Class A common stock to the public at varying prices to be determined by the dealer at the time of resale.

If an underwriter is utilized in the sale of the Class A common stock being offered by this prospectus, an underwriting agreement will be executed with the underwriter at the time of sale and the name of any underwriter will be provided in the prospectus supplement that the underwriter will use to make resales of the Class A common stock to the public. In connection with the sale of the Class A common stock, the Selling Stockholders or the purchasers of Class A common stock for whom the underwriter may act as agent may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the Class A common stock to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for which they may act as agent. Unless otherwise indicated in a prospectus supplement, an agent will be acting on a best efforts basis and a dealer will purchase the Class A common stock as a principal, and may then resell such Class A common stock at varying prices to be determined by the dealer.

Any compensation paid to underwriters, dealers or agents in connection with the offering of the Class A common stock, and any discounts, concessions or commissions allowed by underwriters to participating dealers will be provided in the applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended, and any discounts and commissions received by them and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions. We may enter into agreements to indemnify underwriters, dealers and agents against civil liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make in respect thereof and to reimburse those persons for certain expenses.

19

Any Class A common stock sold pursuant to this prospectus will be listed on the New York Stock Exchange. To facilitate the offering of Class A common stock, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of our Class A common stock. This may include over-allotments or short sales of Class A common stock, which involve the sale by persons participating in the offering of more Class A common stock than were sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option, if any. In addition, these persons may stabilize or maintain the price of the Class A common stock by bidding for or purchasing Class A common stock in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if Class A common stock sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the Class A common stock at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

The specific terms of any lock-up provisions in respect of any given offering will be described in the applicable prospectus supplement.

The underwriters, dealers and agents may engage in transactions with us and our affiliates or the Selling Stockholders and their respective affiliates, or perform services for us and our affiliates or the Selling Stockholders and their respective affiliates, in the ordinary course of business for which they receive compensation.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS TO NON-U.S. HOLDERS

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our Class A common stock offered pursuant to this prospectus, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our Class A common stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of our Class A common stock.

This discussion is limited to Non-U.S. Holders who purchase shares of our Class A common stock offered pursuant to this prospectus and who hold our Class A common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income or the alternative minimum tax. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

21

If an entity treated as a partnership for U.S. federal income tax purposes holds our Class A common stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding our Class A common stock and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATION PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of our Class A common stock that is neither a “U.S. person” nor an entity treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

Distributions

As described in the section entitled “Description of Capital Stock—Dividend Policy,” we do not anticipate declaring or paying dividends to holders of our Class A common stock in the foreseeable future. However, if we do make distributions of cash or property on our Class A common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its Class A common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “—Sale or Other Taxable Disposition.”

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of our Class A common stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). If a Non-U.S. Holder holds our Class A common stock through a financial institution or other intermediary, the Non-U.S. Holder will be required to provide appropriate documentation to the intermediary, which then will be required to provide certification to the applicable withholding agent, either directly or through other intermediaries. A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld

22

by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

Sale or Other Taxable Disposition

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Class A common stock unless:

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition by a Non-U.S. Holder of our Class A common stock will not be subject to U.S. federal income tax if our Class A common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our Class A common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder’s holding period.

23

Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of dividends on our Class A common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our Class A common stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Class A common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our Class A common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or gross proceeds from the sale or other disposition of, our Class A common stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States-owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A common stock, and will apply to payments of gross proceeds from the sale or other disposition of such stock on or after January 1, 2019.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Class A common stock.
