ABOUT THIS PROSPECTUS SUPPLEMENT

This prospectus supplement and the accompanying prospectus are part of a registration statement that we filed with the Securities and Exchange Commission, which we refer to as the “SEC,” utilizing a “shelf” registration process on February 2, 2018, and that was declared effective on February 9, 2018. Under the shelf registration process, we may from time to time, either individually or in combination, offer and sell shares of our Class A common stock or preferred stock, various series of debt securities and/or warrants, as described in this prospectus supplement and the accompanying prospectus in one or more offerings for an aggregate initial offering price of up to $200,000,000. This prospectus supplement describes our offering of shares of our Class A common stock having an aggregate offering price of up to $75,000,000 from time to time through Cowen acting as our agent. We have previously sold $49,643,973 under a prior prospectus supplement during the period from March 2018 through July 29, 2019.

THE COMPANY

We are currently engaged in outdoor billboard advertising and surety insurance and related brokerage businesses. In addition, we hold minority investments in commercial real estate management and brokerage services, a bank focused on servicing the automotive loan market, and a homebuilding company with operations located primarily in the Southeast United States.

Billboards: We commenced our billboard business operations in June 2015 through acquisitions of by our wholly-owned subsidiary, Link Media Holdings, LLC, which we refer to as “LMH,” of smaller billboard companies located in the Southeast United States and Wisconsin. On June 30, 2018, we operated 479 billboard structures.  During July and August 2018, we acquired the membership interests or assets of three larger billboard companies for a combined cash purchase price of $134,798,950, net of adjustments, which increased our overall billboard count to approximately 2,900 billboards.  These transactions include our acquisition on July 31, 2018 of Tammy Lynn Outdoor, LLC for cash and stock consideration of approximately $16 million, our acquisition on August 22, 2018 of substantially all of the assets of Key Outdoor, Inc. for approximately $38 million, and our acquisition on August 31, 2018 of Waitt Outdoor, LLC, for approximately $84 million. We believe that the acquisitions of Waitt Outdoor, LLC and Key Outdoor, Inc., with over 1,600 and 700 billboard structures, respectively, make us a leading outdoor billboard advertising company in the markets we serve in the Midwest. Further, Tammy Lynn Outdoor, LLC is a leading outdoor advertising company in West Virginia with over 250 billboard faces. As of August 1, 2019, we operate approximately 2,900 billboards with approximately 5,400 advertising faces. One of our principal business objectives is to continue to acquire additional billboard assets through acquisitions of existing billboard businesses in the United States when they can be made at what we believe to be attractive prices relative to other opportunities generally available to us.

We are attracted to the outdoor display market due to a number of factors, including high regulatory barriers to building new billboards in some states, growing demand, low maintenance capital expenditures for static billboards, low cost per impression for customers, and the potential opportunity to employ more capital in existing assets at reasonable returns in the form of perpetual easements and digital conversions. In addition, unlike other advertising industries, the Internet has not had a material adverse impact on outdoor advertising revenues. Revenues for out-of-home advertising have continued to rise over the past several years, in contrast to print and other non-Internet based advertising. The billboard industry’s three largest companies are estimated to account for more than 50% of the industry’s total revenues, and several industry sources and our experience suggest that there are a large number of other companies serving the remainder of the market, providing a potentially significant source of billboards which may be acquired in the future.

Surety Insurance: In September 2015, we established an insurance subsidiary, General Indemnity Group, LLC, designed to own and operate insurance businesses generally handling high volume, lower policy limit commercial lines of property and casualty insurance. Our surety insurance business commenced in April 2016 with the acquisition of a surety insurance brokerage business with a national Internet-based presence. In December 2016, we completed the acquisition of United Casualty and Surety Insurance Company, which we refer to as “UCS,” a surety insurance company, which at the time was licensed to issue surety bonds in only nine states. Since that time, we worked to grow the number of states in which UCS can issue surety bonds and, as a result, UCS is now licensed to issue surety insurance in all 50 states and the District of Columbia. In addition, over the last two years, we have also acquired several additional surety insurance brokerage businesses located in various regions of the United States.

Investments in Privately-Held Companies:

In each of our businesses, we hope to expand our geographic reach and market share and seek to develop a competitive advantage and/or brand name for our services, which we hope will be a differentiating factor for customers. Our insurance market primarily services small contractors, small- and medium-sized businesses and individuals that are required to provide surety bonds (1) in connection with their work for government agencies and others, (2) in connection with contractual obligations, or (3) to meet regulatory requirements and other needs. We have expanded the licensing of the UCS business to all 50 states and the District of Columbia. In outdoor advertising, our plan is to continue to grow this business through acquisitions of billboard assets. We also expect to continue to make additional investments in real estate management service businesses, as well as in other businesses. In the future, we expect to expand the range of services we provide in the insurance sector, seek to continue to expand our billboard operations and to possibly consider acquisitions of other businesses, as well as investments, in other sectors. Our decision to expand outside of these current business sectors we serve or in which we have made investments will be based on the opportunity to acquire businesses which we believe provide the potential for sustainable earnings at an attractive level relative to capital employed and, with regard to investment, we believe have the potential to provide attractive returns.

We seek to enter markets where we believe demand for our services will grow in the coming years due to certain barriers to entry and/or to anticipated long-term demand for these services. In the outdoor billboard business, government restrictions often limit the number of additional billboards that may be constructed. At the same time, advances in billboard technology provide the opportunity to improve revenues through the use of digital display technologies and other new technologies. In the surety insurance business, new insurance companies must be licensed by state agencies that impose capital, management and other strict requirements on these insurers. These hurdles are at the individual state level, with statutes often providing wide latitude to regulators to impose judgmental requirements upon new entrants. In addition, new distribution channels in certain areas of surety may provide a new opportunity. In the real estate management services market, we believe the anticipated continued growth of commercial real estate in many sections of the United States will provide opportunities for management services for the foreseeable future. We also believe our investment in both Crescent and DFH provides the opportunity for each company to significantly grow its business. Finally, we invest our available capital and the surplus capital from UCS in a wide range of securities, including equity securities of large cap companies, various corporate and government bonds and U.S. treasuries.

Our principal executive offices are located at 1411 Harney Street, Suite 200, Omaha, Nebraska 68102, and our telephone number is (857) 256-0079. Our website address is www.bostonomaha.com. The information on our website is not incorporated by reference into this prospectus supplement or the accompanying prospectus and should not be considered to be a part of this prospectus supplement or the accompanying prospectus.

THE OFFERING

RISK FACTORS

Investing in our securities involves significant risks and uncertainties. You should carefully consider the risks and uncertainties described in this prospectus supplement and the accompanying prospectus, and the risk factors set forth in our filings with the SEC that are incorporated by reference herein, including the “Risk Factors” section of our latest Annual Report on Form 10-K filed with the SEC, and any updates to those risk factors or new risk factors contained in our subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC, all of which we incorporate by reference herein, before making an investment decision.

Any of the risk factors could materially and negatively affect our businesses, financial condition, results of operations, cash flows, and prospects and the trading price of Class A common stock. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect us in the future. You could lose all or part of your investment in any of our securities.

Risks Related to this Offering

Our management team may invest or spend the proceeds of this offering in ways with which you may not agree or in ways which may not yield a significant return.

Our management will have broad discretion over the use of proceeds from this offering. The net proceeds from this offering will be used for general corporate purposes, which may include financing our existing businesses and operations, and expanding our businesses and operations through additional acquisitions and minority investments and additional hires. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not increase our operating results or enhance the value of our Class A common stock.

You may experience immediate and substantial dilution.

Because the price per share of our Class A common stock being offered may be higher than the book value per share of our Class A common stock, you may suffer immediate substantial dilution in the net tangible book value of the Class A common stock you purchase in this offering. See the section entitled “Dilution” below for a more detailed discussion of the dilution you will incur if you purchase Class A common stock in this offering.

Because the sales of the shares offered hereby will be made directly into the market or in negotiated transactions, the prices at which we sell these shares will vary and these variations may be significant.  Purchasers of the shares we sell, as well as our existing stockholders, will experience significant dilution if we sell shares at prices significantly below the price at which they invested.

The issuance of additional shares of our Class A common stock in future offerings could be dilutive to stockholders if they do not invest in future offerings. Moreover, to the extent that we issue options or warrants to purchase, or securities convertible into or exchangeable for, shares of our Class A common stock in the future and those options, warrants or other securities are exercised, converted or exchanged, stockholders may experience further dilution.

Risks Related to our Business

You may experience future dilution as a result of future equity offerings.

In order to raise additional capital, we may in the future offer additional shares of our Class A common stock or other securities convertible into or exchangeable for our Class A common stock at prices that may not be the same as the price per share in this offering. We may sell shares or other securities in any other offering at a price per share that is less than the price per share paid by investors in this offering, and investors purchasing shares or other securities in the future could have rights superior to existing stockholders. The price per share at which we sell additional shares of our Class A common stock, or securities convertible or exchangeable into Class A common stock, in future transactions may be higher or lower than the price per share paid by investors in this offering.

Because we do not intend to declare cash dividends on our shares of Class A common stock in the foreseeable future, stockholders must rely on appreciation of the value of our Class A common stock for any return on their investment.

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the operation, development and growth of our business. As a result, capital appreciation, if any, of our Class A common stock will be your sole source of gain with respect to your investment for the foreseeable future.

Our investments in publicly-traded securities involve a substantial degree of risk.

In addition to our investments in privately-held companies, we may purchase publicly-traded common stock and other equity securities, including warrants and corporate bonds. Although equity securities have historically generated higher average total returns than fixed-income securities over the long term, equity securities have also generally experienced significantly more volatility in those returns. The publicly-traded securities we acquire may fail to appreciate and may decline in value or become worthless. Investments in equity securities involve a number of significant risks, including the risk of further dilution as a result of additional issuances, inability to access additional capital and failure to pay current distributions. Investments in preferred securities and corporate bonds involve special risks, such as the risk of deferred distributions, credit risk, illiquidity, changes in value based upon interest rates changes and other macroeconomic factors and limited voting rights.

The existing and future indebtedness incurred by our billboard business may adversely affect our ability to obtain additional funds and may increase our vulnerability to economic or business downturns. Failure to comply with the terms of this indebtedness could result in a default by our billboard business that could have material adverse consequences for us.

LMH, which operates our billboard businesses, entered into a credit agreement on August 12, 2019 with a commercial bank which provides LMH and its subsidiaries the opportunity to borrow up to $40 million in principal through a combination of long-term debt and a line of credit. LMH’s current borrowings under the bank credit facility as of August 12, 2019 totaled $18,060,000, all of which represents a term loan. In addition, LMH may incur additional indebtedness in the future. Accordingly, LMH is subject to the risks associated with significant indebtedness, including:

●     LMH must dedicate a portion of its cash flows from operations to pay principal and interest and, as a result, it may have less funds available for operations and other purposes;

●     LMH may find it more difficult and expensive to obtain additional funds through financings, if available at all;

●     LMH is more vulnerable to economic downturns, less able to withstand competitive pressures and less flexible in reacting to changes in the billboard industry and general economic conditions;

●     if LMH defaults under the credit facility, including failing to pay the outstanding principal when due, and if the lender demands payment of a portion or all of the indebtedness, it may not have sufficient funds to make such payments;

●     if LMH is unable to refinance indebtedness on its properties at maturity due to business and market factors, including: disruptions in the capital and credit markets; the estimated cash flows of LMH’s properties and other assets; the value of LMH’s properties and other assets; and financial, competitive, business and other factors, including factors beyond LMH’s control;

●     if refinanced, the terms of a refinancing may not be as favorable as the original terms of the related indebtedness; and

●     if LMH borrows any sums under the line of credit, the interest rate it pays on such debt will be subject to changes in interest rates.

The occurrence of any of these events could materially adversely affect LMH, which would adversely affect our results of operations and financial condition and adversely affect our stock price.

Furthermore, a failure to comply with the obligations contained in the loan agreements governing LMH’s indebtedness could result in an event of default under such agreements which could result in an acceleration of debt under other instruments evidencing indebtedness that contains cross-acceleration or cross-default provisions. If LMH’s indebtedness were to be accelerated, there can be no assurance that its future cash flow or assets would be sufficient to repay in full such indebtedness.

We may in the future rely in part on LMH to provide our company with the funds necessary to make distributions to us to meet our financial obligations. The leverage on LMH assets may affect the funds available to our company if the terms of the debt impose restrictions on the ability of LMH to make distributions to our company. In addition, LMH will generally have to service their debt obligations before making distributions to our company or their parent entity.

Leverage may also result in a requirement for liquidity, which may force the sale of assets at times of low demand and/or prices for such assets.

We may also incur indebtedness under future credit facilities.

If we are unable to refinance our indebtedness on acceptable terms, or at all, we may need to dispose of one or more of our properties or other assets upon disadvantageous terms. In addition, prevailing interest rates or other factors at the time of refinancing could increase our interest expense, and if we grant a security interest in any of our properties, or the properties of our subsidiaries to secure payment of indebtedness and are unable to make loan payments, the lender could foreclose upon such property.

Restrictive covenants in LMH’s indebtedness may limit management’s discretion with respect to certain business matters.

Instruments governing LMH’s indebtedness contain restrictive covenants limiting LMH’s discretion with respect to certain business matters. These covenants could place significant restrictions on, among other things, LMH’s ability to create liens or other encumbrances, to make distributions to us or make certain other payments, investments, loans and guarantees and to sell or otherwise dispose of assets and merge or consolidate with another entity. Covenants also require LMH to meet certain financial ratios and financial condition tests. A failure to comply with any such covenants could result in a default which, if not cured or waived, could permit acceleration of the relevant indebtedness.

If we are unable to manage our interest rate risk effectively, our cash flows and operating results may suffer.

Advances under LMH’s $5 million revolving line of credit bear interest at a variable rate. Although we have not currently borrowed any sums under this line of credit, we may incur indebtedness under this line of credit in the future. Also, we may be required to refinance our debt at higher rates. Accordingly, increases in interest rates above that which we anticipate based upon historical trends would adversely affect our cash flows and we may not be able to hedge such exposure effectively, if at all.

USE OF PROCEEDS

We may issue and sell shares of our Class A common stock having aggregate sales proceeds of up to $75,000,000 from time to time. The amount of proceeds from this offering will depend upon the number of shares of our Class A common stock sold and the market price at which they are sold. There can be no assurance that we will be able to sell any shares under or fully utilize the sales agreement with Cowen as a source of financing. Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount, commissions and proceeds to us, if any, are not determinable at this time.

We intend to use the net proceeds from the sale of any shares of Class A common stock offered under this prospectus supplement for general corporate purposes. General corporate purposes may include, without limitation, financing our existing businesses and operations, and expanding our businesses and operations through additional acquisitions and minority investments and additional hires. Such expansion may include future billboard acquisitions, acquisitions of surety insurance companies and other growth of our insurance activities, additional investments in real estate management, homebuilding and other real estate service businesses, additional investments in subprime automobile lending, and acquisitions of other businesses. We have not determined the amount of net proceeds to be used for any specific purpose, and management will retain broad discretion over the allocation of net proceeds. While we have no current agreements, commitments or understandings for any specific acquisitions at this time, we may use a portion of the net proceeds for these purposes.

This expected use of the net proceeds from this offering represents our intentions based upon our current plans and business conditions and numerous factors, including the factors described under “Risk Factors.” As of the date of this prospectus supplement, we cannot predict with certainty all of the particular uses for the net proceeds to be received upon the completion of this offering or the amounts that we will actually spend on the uses set forth above. The amounts and timing of our actual expenditures and the use of these proceeds may vary significantly depending on numerous factors, including the progress of our expansion efforts and acquisition activities, as well as any unforeseen cash needs. As a result, our management will retain broad discretion over the allocation of the net proceeds from this offering.

Pending our use of the net proceeds from this offering, we intend to invest the net proceeds in a variety of investment-grade, short-term, interest-bearing securities and in certain publicy-traded equity and debt securities.

DIVIDEND POLICY

We have never declared or paid cash dividends on our capital stock. We currently intend to retain all of our future earnings, if any, to finance the operation, development and growth of our business. We do not intend to pay cash dividends to holders of our Class A common stock in the foreseeable future.

DILUTION

Purchasers of Class A common stock offered by this prospectus supplement and the accompanying prospectus will suffer immediate and substantial dilution. Dilution is the amount by which the price paid by the purchasers of Class A common stock in this offering will exceed the net tangible book value per share of Class A common stock immediately after this offering. Our net tangible book value as of June 30, 2019 was approximately $192,757,000 or approximately $8.50 per share of Class A common stock and Class B common stock. Net tangible book value per share represents our total assets, excluding goodwill, and intangibles, less total liabilities and redeemable noncontrolling interests, divided by the number of shares of Class A common stock and Class B common stock outstanding as of June 30, 2019.

After giving effect to the assumed sale of shares of our Class A common stock in the aggregate amount of approximately $75,000,000 at an assumed offering price of $19.98 per share, the last reported sale price of our Class A common stock on August 12, 2019, and after deduction of commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of June 30, 2019 would have been approximately $265,507,000, or $10.05 per share of Class A common stock and Class B common stock. This represents an immediate increase in net tangible book value of $1.55 per share of Class A common stock and Class B common stock to our existing stockholders and an immediate dilution in net tangible book value of $9.93 per share of Class A common stock to investors participating in this offering at an assumed offering price of $19.98 per share. The following table illustrates this per share dilution:

The table above assumes for illustrative purposes that an aggregate of 3,753,753 shares of our Class A common stock are sold at a price of $19.98 per share, the last reported sale price of our Class A common stock on The NASDAQ Capital Market on August 12, 2019, for aggregate gross proceeds of $75,000,000. The shares sold in this offering, if any, will be sold from time to time at various prices. An increase of $1.00 per share in the price at which the shares are sold from the assumed offering price of $19.98 per share shown in the table above, assuming all of our Class A common stock in the aggregate amount of $75,000,000 is sold at that price, would increase our adjusted net tangible book value per share after the offering to $10.11 per share and would increase the dilution in net tangible book value per share to new investors in this offering to $10.87 per share, after deducting commissions and estimated aggregate offering expenses payable by us. A decrease of $1.00 per share in the price at which the shares are sold from the assumed offering price of $19.98 per share shown in the table above, assuming all of our Class A common stock in the aggregate amount of $75,000,000 is sold at that price, would decrease our adjusted net tangible book value per share after the offering to $9.97 per share and would decrease the dilution in net tangible book value per share to new investors in this offering to $9.01 per share, after deducting commissions and estimated aggregate offering expenses payable by us. This information is supplied for illustrative purposes only, and will adjust based on the actual offering prices, the actual number of shares that we offer and sell in this offering and other terms of each sale of shares in this offering.

The information above and in the foregoing table is based upon 21,619,321 shares of our Class A common stock and 1,055,560 shares of our Class B common stock outstanding as of June 30, 2019. The information above and in the foregoing table does not give effect to the exercise of outstanding warrants to purchase 103,032 shares of our Class B common stock at an exercise price of $10.00 per share and 2,524 shares of our Class B common stock at an exercise price of $8.00 per share or the sale of an additional 334,751 shares of our Class A common stock in our prior at the market offering between July 1, 2019 and August 12, 2019. We do not currently have a stock option or similar equity plan and have no plans to establish such a plan.

Furthermore, we may choose to raise additional capital through the sale of equity or equity-linked securities due to market conditions or strategic considerations, even if we believe we have sufficient funds for our current or future operating plans. To the extent that any of our outstanding warrants are exercised or we issue additional shares of Class A common stock or other equity or equity-linked securities in the future, there may be further dilution to investors participating in this offering.

PLAN OF DISTRIBUTION

We have entered into a sales agreement with Cowen, under which we may offer and sell from time to time up to $75,000,000 of shares of our Class A common stock through Cowen acting as our sales agent. Sales of our Class A common stock, if any, will be made at market prices by any method that is deemed to be an “at the market offering” as defined in Rule 415 under the Securities Act, including sales made directly on The NASDAQ Capital Market or any other trading market for our Class A common stock. If authorized by us in writing, Cowen may purchase shares of our Class A common stock as principal.

Cowen will offer our Class A common stock subject to the terms and conditions of the sales agreement on a daily basis or as otherwise agreed upon by us and Cowen. We will designate the maximum amount of Class A common stock to be sold through Cowen on a daily basis or otherwise determine such maximum amount together with Cowen. Subject to the terms and conditions of the sales agreement, Cowen will use its commercially reasonable efforts to sell on our behalf all of the shares of Class A common stock requested to be sold by us. We may instruct Cowen not to sell Class A common stock if the sales cannot be effected at or above the price designated by us in any such instruction. Cowen or we may suspend the offering of our Class A common stock being made through Cowen under the sales agreement upon proper notice to the other party. Cowen and we each have the right, by giving written notice as specified in the sales agreement, to terminate the sales agreement in each party’s sole discretion at any time.

The aggregate compensation payable to Cowen as sales agent equals 3.0% of the gross sales price of the shares sold through it pursuant to the sales agreement. We have also agreed to reimburse Cowen for certain expenses, including Cowen’s FINRA counsel fees in an amount up to $15,000. We estimate that the total expenses of the offering payable by us, excluding commissions payable to Cowen under the sales agreement, will be approximately $45,000.

The remaining sales proceeds, after deducting any expenses payable by us and any transaction fees imposed by any governmental, regulatory, or self-regulatory organization in connection with the sales, will equal our net proceeds for the sale of such Class A common stock.

Cowen will provide written confirmation to us following the close of trading on The NASDAQ Capital Market on each day in which Class A common stock is sold through it as sales agent under the sales agreement. Each confirmation will include the number of shares of Class A common stock sold through it as sales agent on that day, the volume weighted average price of the shares sold, the percentage of the daily trading volume and the net proceeds to us.

We will report at least quarterly the number of shares of Class A common stock sold through Cowen under the sales agreement, the net proceeds to us and the compensation paid by us to Cowen in connection with the sales of Class A common stock.

Settlement for sales of Class A common stock will occur, unless the parties agree otherwise, on the second business day that is also a trading day following the date on which any sales were made in return for payment of the net proceeds to us. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

In connection with the sales of our Class A common stock on our behalf, Cowen will be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to Cowen will be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to Cowen against certain liabilities, including liabilities under the Securities Act. As sales agent, Cowen will not engage in any transaction that stabilizes our common stock.

Our Class A common stock is listed on The NASDAQ Capital Market and trades under the symbol “BOMN.” The transfer agent of our Class A common stock is Colonial Stock Transfer Co. Inc.

Cowen and/or its affiliates have provided, and may in the future provide, various investment banking and other financial services for us for which services they have received and, may in the future receive, customary fees.

THE COMPANY

We are currently engaged in three areas of business: outdoor billboards, surety insurance and related brokerage activities, and investing in real estate management, homebuilding and other real estate businesses. We commenced our current billboard business operations in June 2015, our surety insurance business in April 2016 and have made a series of investments in the real estate management, homebuilding and related real estate services business commencing in September 2015. In December 2016, we completed the acquisition of United Casualty and Surety Insurance Company, which we refer to as “UC&S,” a surety insurance company, which at that time was licensed to conduct business in nine states and is now licensed to conduct business in 44 states and the District of Columbia. As of February 8, 2018 we own and operate approximately 480 billboard structures containing a total of approximately 860 faces, totaling approximately 1,190 advertising spots. Our billboard portfolio includes 37 digital displays. We expect to continue to acquire additional billboard assets through acquisitions of existing billboard businesses in the United States and to expand the licensing of the UC&S business beyond the 44 states and the District of Columbia in which it is currently authorized to issue surety insurance. In addition, we expect to continue to acquire insurance agencies selling surety insurance. Since June 1, 2017 we have completed several small billboard acquisitions, acquired Surety Support Services, Inc. as well as South Coast Surety Insurance Services, LLC, both agencies offering surety bonds in all 50 states, and completed the purchase of a small insurance agency in Maryland selling probate bonds. Additionally, in December 2017, we invested $10 million in Dream Finders Holdings LLC, the parent company of Dream Finders Homes LLC, a national homebuilder that also provides related homebuying services with operations in Florida, Colorado, Georgia, Maryland, South Carolina, Texas and northern Virginia. We also expect to continue to make additional investments in real estate management, homebuilding and other real estate service businesses. In the future, we expect to expand the range of services we provide in each of these sectors and to possibly consider acquisitions of other businesses in different sectors. Our decision to expand outside of these current business sectors we serve will be based on the opportunity to acquire businesses which we believe provide the opportunity for sustainable earnings at an attractive level relative to capital employed.

In each of our businesses, we hope to expand our investment if we estimate the return on incremental capital needed is attractive on an opportunity cost basis. Our insurance market primarily services small contractors, businesses and individuals required to provide surety bonds in connection with their work for government agencies and others, and to meet regulatory licensing and other needs. Our plan is to expand our insurance offerings and underwriting in all 50 states and the District of Columbia. In outdoor billboards, our plan is to continue to grow this business through acquisitions of billboard companies and the purchase of perpetual easements or land underneath our current structures.

Our principal executive offices are located at 1411 Harney Street, Suite 200, Omaha, Nebraska 68102, and our telephone number is (857) 256-0079. Our website address is www.bostonomaha.com. The information on our website is not incorporated by reference into this prospectus and should not be considered to be a part of this prospectus.

RISK FACTORS

Investing in our securities involves significant risks and uncertainties. You should carefully consider the risks and uncertainties described in this prospectus and any accompanying prospectus supplement, and the risk factors set forth in our filings with the SEC that are incorporated by reference herein, including the “Risk Factors” section of our latest Annual Report on Form 10-K filed with the SEC, as amended, and any updates to those risk factors or new risk factors contained in our subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC, all of which we incorporate by reference herein, before making an investment decision.

Any of the risk factors could materially and negatively affect our businesses, financial condition, results of operations, cash flows, and prospects and the trading price of Class A common stock. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also adversely affect us in the future. You could lose all or part of your investment in any of our securities.

USE OF PROCEEDS

Unless otherwise set forth in the applicable prospectus supplement, we intend to use the net proceeds from the sale of any securities offered under this prospectus for general corporate purposes unless the applicable prospectus supplement provides otherwise. General corporate purposes may include, without limitation, financing our existing businesses and operations, and expanding our businesses and operations through additional hires, strategic alliances and acquisitions. Such expansion may include future billboard acquisitions, acquisitions of surety insurance companies and other growth of our insurance activities, additional investments in real estate management, homebuilding and other real estate service businesses and acquisitions of other businesses. We have not determined the amount of net proceeds to be used for any specific purpose, and management will retain broad discretion over the allocation of net proceeds.

Pending our use of the net proceeds from this offering, we intend to invest the net proceeds in a variety of investment-grade, short-term, interest-bearing securities.

DESCRIPTION OF CAPITAL STOCK

The following summarizes the material terms of our Class A common stock, Class B common stock and preferred stock and related provisions of our certificate of incorporation and our bylaws. This description also summarizes the principal agreements relating to our Class A common stock and Class B common stock. Because it is only a summary, it does not contain all the information that may be important to you. For a complete description, you should refer to our certificate of incorporation and bylaws and the agreements referred to below, copies of which are filed as exhibits incorporated by reference to the registration statement of which this prospectus forms a part.

General

Our authorized capital stock consists of 20,000,000 shares of common stock, par value $0.001 per share, of which 18,838,884 shares have been designated as Class A common stock and the remaining 1,161,116 shares as Class B common stock. In addition, we have authorized 1,000,000 shares of preferred stock, par value $0.001 per share, none of which are outstanding. As of February 1, 2018, 13,307,157 shares of our Class A common stock were outstanding and 1,055,560 shares of our Class B common stock were outstanding.

DESCRIPTION OF CLASS A COMMON STOCK

Our Class A common stock is identical to the Class B common stock with respect to all rights and privileges, except that (i) the Class B common stock is convertible into shares of Class A common stock at a 1:1 ratio; (ii) each share of Class B common stock is entitled to 10 votes in connection with stockholder votes, while each share of Class A common stock is entitled to one vote; (iii) two directors are elected exclusively by the holders of Class B common stock as a separate class as described below; and (iv) the Class B common stock has certain special voting provisions as described below.

Dividend Rights

Subject to preferences that may be applicable to any then-outstanding preferred stock, holders of our Class A common stock and Class B common stock are entitled to receive ratably those dividends, if any, as may be declared from time to time by our board of directors out of legally available funds.

Voting Rights

Each holder of our Class A common stock is entitled to one vote for each share owned of record on all matters voted upon by stockholders, and each holder of our Class B common stock is entitled to 10 votes for each share owned of record on all matters voted upon by stockholders. A majority vote is required for all action to be taken by stockholders, except as otherwise provided for in our certificate of incorporation and bylaws or as required by law, including the election of directors in an election that is determined by our board of directors to be a contested election, which requires a plurality. Our certificate of incorporation provides that either our board of directors or the holders of at least a majority of the total voting power of the outstanding shares of our capital stock are expressly authorized to make, alter or repeal our bylaws.

Liquidation Rights

In the event of our liquidation, dissolution or winding-up, the holders of our Class A common stock and Class B common stock are entitled to share equally and ratably in our assets, if any, remaining after the payment of all of our debts and liabilities and the liquidation preference of any outstanding preferred stock.

Other Rights

Neither our Class B common stock nor our Class A common stock has any preemptive rights, cumulative voting rights or redemption or sinking fund provisions.

Special Provisions Regarding our Class B Common Stock

The holders of record of the shares of Class B common stock, exclusively and as a separate class, shall be entitled to elect two directors to our board of directors, which number of Class B Directors may be reduced pursuant to the terms and conditions of the Amended and Restated Voting and First Refusal Agreement among the Company, Magnolia and Boulderado. Any Class B Director may be removed without cause by, and only by, the affirmative vote of the holders of eighty percent (80%) of the shares of Class B common stock exclusively and as a separate class, given either at a special meeting of such stockholders duly called for that purpose or pursuant to a written consent of such stockholders.

At any time when shares of Class B common stock are outstanding, we may not, without the affirmative vote of all of the Class B Directors:

Composition of our Board of Directors

Our Board of Directors currently consists of six members: Co-Chairmen Alex B. Rozek and Adam K. Peterson, along with Bradford B. Briner, Brendan J. Keating, Frank H. Kenan II and Vishnu Srinivasan.

Anti-Takeover Effects of Delaware Law and Our Certificate of Incorporation and Bylaws

Some provisions of Delaware law and of our certificate of incorporation and bylaws could have the effect of delaying, deferring or discouraging another party from acquiring control of us. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors.

Requirements for Advance Notification of Stockholder Nominations and Proposals

Our bylaws establish advance notice procedures with respect to stockholder proposals, other than proposals made by or at the direction of our board of directors. Our bylaws also establish advance notice procedures with respect to the nomination of candidates for election as directors, other than nominations made by or at the direction of our board of directors or by a committee appointed by our board of directors. These provisions may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed, and may also discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of us.

Calling Special Stockholder Meetings

Our certificate of incorporation and bylaws provide that special meetings of our stockholders may be called only by our board of directors or by stockholders owning at least 25% in amount of our entire capital stock issued and outstanding, and entitled to vote.

Stockholder Action by Written Consent

The Delaware General Corporation Law, which we refer to as the “DGCL,” permits stockholder action by written consent unless otherwise provided by our certificate of incorporation. During such period of time as we remain a controlled company under NASDAQ rules, we intend to allow stockholders to take action by written consent in accordance with our bylaws. At such time as we no longer qualify as a controlled company, our bylaws will provide that stockholders will no longer be able to take action by written consent and will only be able to take action at a duly convened meeting of our stockholders.

Undesignated Preferred Stock

Our board of directors is authorized to issue, without stockholder approval, preferred stock with such terms as our board of directors may determine. The ability to authorize undesignated preferred stock makes it possible for our board of directors to issue one or more series of preferred stock with voting or other rights or preferences that could impede the success of any attempt to change control of the company.

Delaware Anti-Takeover Statute

We have elected to be governed by Section 203 of the DGCL, an anti-takeover law, which we refer to as “Section 203.” This law prohibits a publicly held Delaware corporation from engaging under certain circumstances in a business combination with any interested stockholder for a period of three years following the date that the stockholder became an interested stockholder, unless:

Section 203 defines “business combination” to include: any merger or consolidation involving us and the interested stockholder; any sale, transfer, pledge or other disposition of 10% or more of our assets involving the interested stockholder; in general, any transaction that results in the issuance or transfer by us of any of our stock to the interested stockholder; or the receipt by the interested stockholder of the benefit of any loans, advances, guarantees, pledges or other financial benefits provided by or through us. In general, Section 203 defines an interested stockholder as any 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 any such entity or person. A Delaware corporation may opt out of this provision by express provision in its original certificate of incorporation or by amendment to its certificate of incorporation or bylaws approved by its stockholders. We have opted to be governed by this provision and, accordingly, we will be subject to any anti-takeover effects of Section 203.

Removal of Directors; Vacancies

Our certificate of incorporation provides that, other than the two directors elected by the holders of our Class B common stock, directors may be removed with or without cause upon the affirmative vote of holders of at least a majority of the total voting power of the outstanding shares of the capital stock of the company entitled to vote in any annual election of directors or class of directors, voting together as a single class. In addition, our certificate of incorporation provides that vacancies, including those resulting from newly created directorships or removal of directors, may only be filled by a majority of the directors then in office or by a sole remaining director. This may deter a stockholder from increasing the size of our board of directors and gaining control of the board of directors by filling the remaining vacancies with its own nominees.

Limitation on Directors’ Liability

Our certificate of incorporation and bylaws will provide for indemnification of our directors to the fullest extent permitted by the DGCL. The DGCL permits a corporation to limit or eliminate a director’s personal liability to the corporation or the holders of its capital stock for breach of duty. This limitation is generally unavailable for acts or omissions by a director which (i) were in bad faith, (ii) were the result of active and deliberate dishonesty and were material to the cause of action so adjudicated or (iii) involved a financial profit or other advantage to which such director was not legally entitled. The DGCL also prohibits limitations on director liability for acts or omissions which resulted in a violation of a statute prohibiting certain dividend declarations, certain payments to stockholders after dissolution and particular types of loans. The effect of these provisions is to eliminate the rights of our company and our stockholders (through stockholders’ derivative suits on behalf of our company) to recover monetary damages against a director for breach of fiduciary duty as a director (including breaches resulting from grossly negligent behavior), except in the situations described above. These provisions will not limit the liability of directors under the federal securities laws of the United States.

Choice of Forum

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for: (a) any derivative action or proceeding brought on our behalf; (b) any action asserting a breach of a fiduciary duty owed by any of our directors, officers, employees or agents to us or our stockholders; (c) any action asserting a claim pursuant to any provision of the DGCL, our certificate of incorporation or our bylaws; or (d) any action asserting a claim governed by the internal affairs doctrine. However, it is possible that a court could find our forum selection provision to be inapplicable or unenforceable.

Amended and Restated Voting and First Refusal Agreement

Each of Boulderado and Magnolia agreed as part of the Amended and Restated Voting and First Refusal Agreement to elect as the Class B Directors each of Alex B. Rozek, as a nominee of Boulderado, and Adam K. Peterson, as a nominee of Magnolia. In the event of (a) the death of a Class B Director, (b) the incapacitation of a Class B Director as a result of illness or accident, which makes it reasonably unlikely that the Class B Director will be able to perform his normal duties for the Company for a period of ninety (90) days, or (c) a change of control of Boulderado or Magnolia, then the Class B stockholder which nominated such deceased or incapacitated Class B Director, or the Class B stockholder undergoing such change of control, shall convert all of such Class B common stock into shares of our Class A common stock, in accordance with the procedures set forth in the our certificate of incorporation. The Amended and Restated Voting and First Refusal Agreement also provides each of the Company and the other party to the Voting Agreement with the right of first refusal to purchase the Class B common stock proposed to be sold by the other holder of Class B common stock.

Listing

Our Class A common stock is listed on the NASDAQ Capital Market under the symbol “BOMN.”

Transfer Agent and Registrar

The transfer agent and registrar for our Class A common stock is Colonial Stock Transfer Co. Inc.

DESCRIPTION OF PREFERRED STOCK

We are authorized to issue up to 1,000,000 shares of preferred stock, par value $0.001 per share. As of February 1, 2018, there were no shares of our preferred stock outstanding.

Our board of directors may, without further action by our stockholders, from time to time, direct the issuance of shares of preferred stock in series and may, at the time of issuance, determine the rights, preferences and limitations of each series, including voting rights, dividend rights and redemption and liquidation preferences. Satisfaction of any dividend preferences of outstanding shares of our preferred stock would reduce the amount of funds available for the payment of dividends on shares of our Class A common stock and Class B common stock. Holders of shares of our preferred stock may be entitled to receive a preference payment in the event of any liquidation, dissolution or winding-up of our Company before any payment is made to the holders of shares of our Class A common stock and Class B common stock. In some circumstances, the issuance of shares of preferred stock may render more difficult or tend to discourage a merger, tender offer or proxy contest, the assumption of control by a holder of a large block of our securities or the removal of incumbent management. Upon the affirmative vote of our board of directors, without stockholder approval, we may issue shares of preferred stock with voting and conversion rights which could adversely affect the holders of shares of our Class A common stock and Class B common stock.

If we offer a specific series of preferred stock under this prospectus, we will describe the terms of the preferred stock in the prospectus supplement for such offering and will file a copy of the certificate establishing the terms of the preferred stock with the SEC. To the extent required, this description will include:

The preferred stock offered by this prospectus, when issued, will not have, or be subject to, any preemptive or similar rights.

Transfer Agent and Registrar

The transfer agent and registrar for any series of preferred stock will be set forth in each applicable prospectus supplement.

DESCRIPTION OF DEBT SECURITIES

We may issue debt securities from time to time, in one or more series, as either senior or subordinated debt or as senior or subordinated convertible debt. While the terms we have summarized below will apply generally to any debt securities that we may offer under this prospectus, we will describe the particular terms of any debt securities that we may offer in more detail in the applicable prospectus supplement. The terms of any debt securities offered under a prospectus supplement may differ from the terms described below. Unless the context requires otherwise, whenever we refer to the indenture, we also are referring to any supplemental indentures that specify the terms of a particular series of debt securities.

We will issue the debt securities under an indenture that we will enter into with a trustee named in the indenture. The indenture will be qualified under the Trust Indenture Act of 1939, as amended, which we refer to as the “Trust Indenture Act.” We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part, and supplemental indentures and forms of debt securities containing the terms of the debt securities being offered will be filed as exhibits to the registration statement of which this prospectus is a part or will be incorporated by reference from reports that we file with the SEC.

The following summary of material provisions of the debt securities and the indenture is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture applicable to a particular series of debt securities. We urge you to read the applicable prospectus supplements and any related free writing prospectuses related to the debt securities that we may offer under this prospectus, as well as the complete indenture that contains the terms of the debt securities.

General

The indenture does not limit the amount of debt securities that we may issue. It provides that we may issue debt securities up to the principal amount that we may authorize and may be in any currency or currency unit that we may designate. Except for the limitations on consolidation, merger and sale of all or substantially all of our assets contained in the indenture, the terms of the indenture do not contain any covenants or other provisions designed to give holders of any debt securities protection against changes in our operations, financial condition or transactions involving us.

We may issue the debt securities issued under the indenture as “discount securities,” which means they may be sold at a discount below their stated principal amount. These debt securities, as well as other debt securities that are not issued at a discount, may be issued with “original issue discount,” or OID, for U.S. federal income tax purposes because of interest payment and other characteristics or terms of the debt securities. Material U.S. federal income tax considerations applicable to debt securities issued with OID will be described in more detail in any applicable prospectus supplement.

We will describe in the applicable prospectus supplement the terms of the series of debt securities being offered, including:

 Conversion or Exchange Rights

We will set forth in the applicable prospectus supplement the terms on which a series of debt securities may be convertible into or exchangeable for our common stock or our other securities. We will include provisions as to settlement upon conversion or exchange and whether conversion or exchange is mandatory, at the option of the holder or at our option. We may include provisions pursuant to which the number of shares of our capital stock or our other securities that the holders of the series of debt securities receive would be subject to adjustment.

Consolidation, Merger or Sale

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the indenture will not contain any covenant that restricts our ability to merge or consolidate, or sell, convey, transfer or otherwise dispose of our assets as an entirety or substantially as an entirety. However, any successor to or acquiror of such assets (other than a subsidiary of ours) must assume all of our obligations under the indenture or the debt securities, as appropriate.

Events of Default under the Indenture

Unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, the following are events of default under the indenture with respect to any series of debt securities that we may issue:

If an event of default with respect to debt securities of any series occurs and is continuing, other than an event of default specified in the last bullet point above, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice to us in writing, and to the trustee if notice is given by such holders, may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. If an event of default specified in the last bullet point above occurs with respect to us, the principal amount of and accrued interest, if any, of each issue of debt securities then outstanding shall be due and payable without any notice or other action on the part of the trustee or any holder.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respect to the series and its consequences, except defaults or events of default regarding payment of principal, premium, if any, or interest, unless we have cured the default or event of default in accordance with the indenture. Any waiver shall cure the default or event of default.

Subject to the terms of the indenture, if an event of default under an indenture shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under such indenture at the request or direction of any of the holders of the applicable series of debt securities, unless such holders have offered the trustee reasonable indemnity. The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, provided that:

A holder of the debt securities of any series will have the right to institute a proceeding under the indenture or to appoint a receiver or trustee, or to seek other remedies only if:

These limitations do not apply to a suit instituted by a holder of debt securities if we default in the payment of the principal, premium, if any, or interest on, the debt securities.

We will periodically file statements with the trustee regarding our compliance with specified covenants in the indenture.

Modification of Indenture; Waiver

We and the trustee may change an indenture without the consent of any holders with respect to specific matters:

In addition, under the indenture, the rights of holders of a series of debt securities may be changed by us and the trustee with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each series that is affected. However, unless we provide otherwise in the prospectus supplement applicable to a particular series of debt securities, we and the trustee may make the following changes only with the consent of each holder of any outstanding debt securities affected:

Discharge

Each indenture provides that we can elect to be discharged from our obligations with respect to one or more series of debt securities, except for specified obligations, including obligations to:

In order to exercise our rights to be discharged, we must deposit with the trustee money or government obligations sufficient to pay all the principal of, any premium, if any, and interest on, the debt securities of the series on the dates payments are due.

Form, Exchange and Transfer

We will issue the debt securities of each series only in fully registered form without coupons and, unless we provide otherwise in the applicable prospectus supplement, in denominations of $1,000 and any integral multiple thereof. The indenture provides that we may issue debt securities of a series in temporary or permanent global form and as book-entry securities that will be deposited with, or on behalf of, a depositary named by us and identified in the applicable prospectus supplement with respect to that series. To the extent the debt securities of a series are issued in global form and as book-entry, a description of terms relating to such securities will be set forth in the applicable prospectus supplement.

At the option of the holder, subject to the terms of the indenture and the limitations applicable to global securities described in the applicable prospectus supplement, the holder of the debt securities of any series can exchange the debt securities for other debt securities of the same series, in any authorized denomination and of like tenor and aggregate principal amount.

Subject to the terms of the indenture and the limitations applicable to global securities set forth in the applicable prospectus supplement, holders of the debt securities may present the debt securities for exchange or for registration of transfer, duly endorsed or with the form of transfer endorsed thereon duly executed if so required by us or the security registrar, at the office of the security registrar or at the office of any transfer agent designated by us for this purpose. Unless otherwise provided in the debt securities that the holder presents for transfer or exchange, we will impose no service charge for any registration of transfer or exchange, but we may require payment of any taxes or other governmental charges.

We will name in the applicable prospectus supplement the security registrar, and any transfer agent in addition to the security registrar, that we initially designate for any debt securities. We may at any time designate additional transfer agents or rescind the designation of any transfer agent or approve a change in the office through which any transfer agent acts, except that we will be required to maintain a transfer agent in each place of payment for the debt securities of each series.

If we elect to redeem the debt securities of any series, we will not be required to:

Information Concerning the Trustee

The trustee, other than during the occurrence and continuance of an event of default under an indenture, undertakes to perform only those duties as are specifically set forth in the applicable indenture. Upon an event of default under an indenture, the trustee must use the same degree of care as a prudent person would exercise or use in the conduct of his or her own affairs. Subject to this provision, the trustee is under no obligation to exercise any of the powers given it by the indenture at the request of any holder of debt securities unless it is offered reasonable security and indemnity against the costs, expenses and liabilities that it might incur.

Payment and Paying Agents

Unless we otherwise indicate in the applicable prospectus supplement, we will make payment of the interest on any debt securities on any interest payment date to the person in whose name the debt securities, or one or more predecessor securities, are registered at the close of business on the regular record date for the interest.

We will pay principal of and any premium and interest on the debt securities of a particular series at the office of the paying agents designated by us, except that unless we otherwise indicate in the applicable prospectus supplement, we will make interest payments by check that we will mail to the holder or by wire transfer to certain holders. Unless we otherwise indicate in the applicable prospectus supplement, we will designate the corporate trust office of the trustee as our sole paying agent for payments with respect to debt securities of each series. We will name in the applicable prospectus supplement any other paying agents that we initially designate for the debt securities of a particular series. We will maintain a paying agent in each place of payment for the debt securities of a particular series.

All money we pay to a paying agent or the trustee for the payment of the principal of or any premium or interest on any debt securities that remains unclaimed at the end of two years after such principal, premium or interest has become due and payable will be repaid to us, and the holder of the debt security thereafter may look only to us for payment thereof.

Governing Law

The indenture and the debt securities will be governed by and construed in accordance with the internal laws of the State of Delaware, except to the extent that the Trust Indenture Act of 1939 is applicable.

DESCRIPTION OF WARRANTS

The following description, together with the additional information we may include in any applicable prospectus supplement and in any related free writing prospectus that we may authorize to be distributed to you, summarizes the material terms and provisions of the warrants that we may offer under this prospectus, which may consist of warrants to purchase Class A common stock, Class B common stock, preferred stock and/or debt securities and may be issued in one or more series. Warrants may be offered independently or in combination with Class A common stock, Class B common stock, preferred stock or debt securities offered by any prospectus supplement. While the terms we have summarized below will apply generally to any warrants that we may offer under this prospectus, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. The following description of warrants will apply to the warrants offered by this prospectus unless we provide otherwise in the applicable prospectus supplement. The applicable prospectus supplement for a particular series of warrants may specify different or additional terms.

We have filed forms of the warrant agreement and warrant certificate containing the terms of the warrants that may be offered as exhibits to the registration statement of which this prospectus is a part. We will file as exhibits to the registration statement of which this prospectus is a part, or will incorporate by reference from reports that we file with the SEC, the form of warrant and/or the warrant agreement and warrant certificate, as applicable, that contain the terms of the particular series of warrants we are offering, and any supplemental agreements, before the issuance of such warrants. The following summaries of material terms and provisions of the warrants are subject to, and qualified in their entirety by reference to, all the provisions of the form of warrant and/or the warrant agreement and warrant certificate, as applicable, and any supplemental agreements applicable to a particular series of warrants that we may offer under this prospectus. We urge you to read the applicable prospectus supplement related to the particular series of warrants that we may offer under this prospectus, as well as any related free writing prospectus, and the complete form of warrant and/or the warrant agreement and warrant certificate, as applicable, and any supplemental agreements, that contain the terms of the warrants.

General

We will describe in the applicable prospectus supplement the terms of the series of warrants being offered, including, to the extent applicable:

Before exercising their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon such exercise, including:

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. The warrants may be exercised as set forth in the prospectus supplement relating to the warrants offered. Unless we otherwise specify in the applicable prospectus supplement, warrants may be exercised at any time up to the specified time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Upon receipt of payment and the warrant or warrant certificate, as applicable, properly completed and duly executed at the corporate trust office of the warrant agent, if any, or any other office, including ours, indicated in the prospectus supplement, we will, as soon as practicable, issue and deliver the securities purchasable upon such exercise. If less than all of the warrants (or the warrants represented by such warrant certificate) are exercised, a new warrant or a new warrant certificate, as applicable, will be issued for the remaining warrants.

Governing Law

Unless we provide otherwise in the applicable prospectus supplement, the warrants and warrant agreements, and any claim, controversy or dispute arising under or related to the warrants or warrant agreements, will be governed by and construed in accordance with the laws of the State of Delaware.

Enforceability of Rights by Holders of Warrants

Each warrant agent, if any, will act solely as our agent under the applicable warrant agreement and will not assume any obligation or relationship of agency or trust with any holder of any warrant. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case of any default by us under the applicable warrant agreement or warrant, including any duty or responsibility to initiate any proceedings at law or otherwise, or to make any demand upon us. Any holder of a warrant may, without the consent of the related warrant agent or the holder of any other warrant, enforce by appropriate legal action its right to exercise, and receive the securities purchasable upon exercise of, its warrants.

FORMS OF SECURITIES

Each debt security and warrant will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Unless otherwise provided in the applicable prospectus supplement, certificated securities in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities or warrants represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

        We may issue the registered debt securities and warrants in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

        If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

        Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture or warrant agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture or warrant agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture or warrant agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture or warrant agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

        Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustees, the warrant agents or any other agent of ours, agent of the trustees or agent of the warrant agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

        We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment to holders of principal, premium, interest or other distribution of underlying securities or other property on that registered global security, will immediately credit participants' accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers or registered in “street name,” and will be the responsibility of those participants.

        If the depositary for any of the securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent or other relevant agent of ours or theirs. It is expected that the depositary's instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

CERTAIN U.S. FEDERAL INCOME AND ESTATE TAX CONSIDERATIONS

FOR NON-U.S. HOLDERS OF SECURITIES

THIS SUMMARY IS NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR SECURITIES. HOLDERS OF OUR SECURITIES ARE ENCOURAGED TO CONSULT WITH THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICATION AND EFFECT OF ANY U.S. NONINCOME, STATE, LOCAL, NON-U.S. INCOME AND OTHER TAX LAWS) OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR SECURITIES.

The following is a summary of certain United States federal income and estate tax consequences to a non-U.S. holder (as defined herein) of the purchase, ownership and disposition of our securities as of the date hereof. This summary deals only with securities that are held as a capital asset.

Except as modified for estate tax purposes (as discussed below), a “non-U.S. holder” means a beneficial owner of our securities that, for United States federal income tax purposes, is not a partnership or:

This summary is based upon provisions of the Internal Revenue Code of 1986, as amended, which we refer to as the “Code,” and regulations, rulings and judicial decisions, all as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in United States federal income and estate tax consequences different from those summarized below. This summary does not address all aspects of United States federal income and estate taxes that may be relevant to a non- U.S. holder in light of that holder’s particular circumstances or that may be applicable to holders subject to special treatment under U.S. federal income tax law (including, for example, financial institutions, dealers in securities, traders in securities that elect mark-to-market treatment, insurance companies, tax-exempt entities, holders who acquired our securities pursuant to the exercise of employee stock options or otherwise as compensation, entities or arrangements treated as partnerships for U.S. federal income tax purposes, holders liable for the alternative minimum tax, certain former citizens or former long-term residents of the United States, holders who hold our securities as part of a hedge, straddle, constructive sale or conversion transaction, and holders who own or have owned (directly, indirectly or constructively) five percent or more of our Class A common stock or our combined Class A and Class B common stock (by vote or value), and does not address the effects of any other United States federal tax laws (including gift tax or the Medicare tax on certain investment income) and does not deal with foreign, state, local or other tax considerations that may be relevant to holders in light of their particular circumstances. In addition, it does not represent a detailed description of the United States federal income or estate tax consequences applicable to you if you are subject to special treatment under the United States federal income tax laws (including if you are a United States expatriate, “controlled foreign corporation,” “passive foreign investment company” or a partnership or other pass-through entity for United States federal income tax purposes). We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

If an entity treated as a partnership for United States federal income tax purposes holds our securities, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership considering an investment in our securities, you should consult your tax advisors.

If you are considering the purchase of our securities, you should consult your own tax advisors concerning the particular United States federal tax consequences to you of the ownership of our securities, as well as the consequences to you arising under the laws of any other taxing jurisdiction.

Dividends

We do not intend to pay dividends for the foreseeable future. The declaration and payment of any future dividends will be at the sole discretion of our board of directors and will depend upon, among other things, our earnings, financial condition, capital requirements, level of indebtedness, contractual restrictions, restrictions imposed by state insurance commissions with respect to payment of dividends, and other considerations that our board of directors deems relevant. Subject to the discussion of backup withholding and FATCA (as defined herein) below, dividends paid to a non-U.S. holder of our securities generally will be subject to United States federal withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. A distribution will constitute a dividend for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits as determined for U.S. federal income tax purposes. Any distribution not constituting a dividend will be treated as first reducing the adjusted basis in the non-U.S. holder’s shares of our securities and, to the extent it exceeds the adjusted basis in the non-U.S. holder’s shares of our securities, as gain from the sale or exchange of such shares.

However, dividends that are effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States are generally not subject to the United States federal withholding tax, provided certain certification and disclosure requirements are satisfied. Instead, such dividends are subject to United States federal income tax on a net income basis in generally the same manner as if the non-U.S. holder were a United States person as defined under the Code, unless an applicable income tax treaty provides otherwise. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, on its effectively connected earnings and profits, subject to adjustments.

A non-U.S. holder of our securities who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, as discussed below, for dividends will be required (a) to complete the applicable Internal Revenue Service Form W-8 and certify under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if our securities are held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable United States Treasury regulations. Special certification and other requirements apply to certain non-U.S. holders that are pass-through entities rather than corporations or individuals.

A non-U.S. holder of our securities eligible for a reduced rate of United States withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the Internal Revenue Service.

Gain on Disposition of Securities

Subject to the discussion of backup withholding and FATCA below, any gain realized on the sale, exchange or other taxable disposition of our securities generally will not be subject to United States federal income or withholding tax unless:

A non-U.S. holder described in the first bullet point immediately above will be subject to United States federal income tax on the net gain derived from the disposition on a net income basis in generally the same manner as if the non-U.S. holder were a United States person as defined under the Code, unless an applicable income tax treaty provides otherwise. If a non-U.S. holder that is a foreign corporation falls under the first bullet point immediately above, it may also be subject to the branch profits tax equal to 30% (or such lower rate as may be specified by an applicable income tax treaty) of its effectively connected earnings and profits, subject to adjustments.

Unless an applicable income tax treaty provides otherwise, an individual non-U.S. holder described in the second bullet point immediately above will be subject to a flat 30% United States federal income tax on the gain derived from the disposition, which may be offset by United States source capital losses, even though the individual is not considered a resident of the United States.

With respect to the third bullet point above, because the determination of whether we are a United States real property holding corporation depends on the fair market value of our interests in real property located within the United States and the classification of certain of our assets, including billboard assets, and there can be no assurance that are not, or will become, a USRPHC. However, even if we are or become a “USRPHC,” if our securities are considered to be regularly traded on an established securities market (within the meaning of 897(c)(3) of the Code), only a non-U.S. holder who, actually or constructively, holds or held (at any time during the shorter of the five-year period preceding the date of disposition or the holder’s holding period) more than 5% of our securities will be subject to United States federal income tax on any gain derived from the disposition of our securities. We expect our Class A common stock to be “regularly traded” on an established securities market, although we cannot guarantee it will be so traded.

Federal Estate Tax

Securities held (or deemed held) at the time of death by an individual non-U.S. holder who is neither a citizen or resident of the United States (as specifically defined for United States estate tax purposes) will be included in such holder’s gross estate for United States federal estate tax purposes, unless an applicable estate tax treaty provides otherwise.

Information Reporting and Backup Withholding

U.S. backup withholding (currently at a rate of 28%) is imposed on certain payments to persons that fail to furnish the information required under the U.S. information reporting requirements. Dividends paid to a non-U.S. holder of our securities generally will be exempt from backup withholding if the non-U.S. holder provides to the applicable withholding agent a properly executed Internal Revenue Service Form W-8BEN, W-8BEN-E or W-8ECI (as applicable) or otherwise establishes an exemption.

We must report annually to the Internal Revenue Service and to each non-U.S. holder the amount of dividends paid to such holder and the tax withheld with respect to such dividends, regardless of whether withholding was required. Copies of the information returns reporting such dividends and withholding may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable income tax treaty.

Under U.S. Treasury Regulations, the payment of proceeds from the disposition of our securities by a non-U.S. holder effected at a U.S. office of a broker generally will be subject to information reporting and backup withholding, unless the beneficial owner, under penalties of perjury, certifies, among other things, its status as a non-U.S. holder or otherwise establishes an exemption. The certification procedures described above will satisfy these certification requirements as well. The payment of proceeds from the disposition of our securities by a non-U.S. holder effected at a non-U.S. office of a broker generally will not be subject to backup withholding and information reporting, except that information reporting (but generally not backup withholding) may apply to payments if the broker is:

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 United States federal income tax liability provided the required information is timely furnished to the Internal Revenue Service.

Additional Withholding Requirements

Under Sections 1471 through 1474 of the Code (such Sections commonly referred to as “FATCA”), a 30% United States federal withholding tax may apply to any dividends paid on our securities and, for a disposition of our securities occurring after December 31, 2018, the gross proceeds from such disposition, in each case paid to (i) a “foreign financial institution” (as specifically defined in the Code), whether such foreign financial institution is the beneficial owner or an intermediary, which does not provide sufficient documentation, typically on Internal Revenue Service Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner which avoids withholding, or (ii) a “non-financial foreign entity” (as specifically defined in the Code), whether such non-financial foreign entity is the beneficial owner or an intermediary, which does not provide sufficient documentation, typically on Internal Revenue Service Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above under “—Dividends,” the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. You should consult your own tax advisor regarding these requirements and whether they may be relevant to your purchase, ownership and disposition of our securities.

PLAN OF DISTRIBUTION

We may sell securities through any one or more of the following methods from time to time:

• to or through underwriters, brokers or dealers; 

• through agents, including transactions in which a broker or dealer as agent solicits purchasers and ordinary brokerage transactions by the broker or dealer as agent; 

• directly to one or more other purchasers in negotiated sales or competitively bid transactions; 

• through a block trade in which the broker or dealer engaged to handle the block trade will attempt to sell the securities as agent, but may position and resell a portion of the block as principal to facilitate the transaction; or 

• through a combination of any of the above methods of sale.

        We may directly solicit offers to purchase securities, or agents may be designated to solicit such offers. We will, in the prospectus supplement relating to such offering, name any agent that could be viewed as an underwriter under the Securities Act, and describe any commissions that we must pay. Any such agent will be acting on a best efforts basis for the period of its appointment or, if indicated in the applicable prospectus supplement, on a firm commitment basis. This prospectus may be used in connection with any offering of our securities through any of these methods or other methods described in the applicable prospectus supplement.

The distribution of the securities may be effected from time to time in one or more transactions:

• at a fixed price, or prices, which may be changed from time to time; 

• at market prices prevailing at the time of sale; 

• at prices related to such prevailing market prices; or 

• at negotiated prices.

        Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

        The prospectus supplement with respect to the securities of a particular series will describe the terms of the offering of the securities, including the following:

• the name of the agent or any underwriters; 

• the public offering or purchase price; 

• any discounts and commissions to be allowed or paid to the agent or underwriters; 

• all other items constituting underwriting compensation; 

• any discounts, concessions and commissions to be allowed or paid to dealers; and 

• any exchanges on which the securities will be listed.

        If any underwriters or agents are utilized in the sale of the securities in respect of which this prospectus is delivered, we will enter into an underwriting agreement or other agreement with them at the time of sale to them, and we will set forth in the prospectus supplement relating to such offering the names of the underwriters or agents and the terms of the related agreement with them.

        If a dealer is utilized in the sale of the securities in respect of which the prospectus is delivered, we will sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale.

If we offer securities in a subscription rights offering to our existing security holders, we may enter into a standby underwriting agreement with dealers, acting as standby underwriters. We may pay the standby underwriters a commitment fee for the securities they commit to purchase on a standby basis. If we do not enter into a standby underwriting arrangement, we may retain a dealer-manager to manage a subscription rights offering for us.

        Agents, underwriters, dealers and other persons may be entitled under agreements which they may enter into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, and may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

        We or our underwriters, broker-dealers, or agent may make sales of our shares of Class A common stock at market prices by any method that is deemed to be an “at the market” offering as defined in Rule 415 under the Securities Act, including sales made directly on The NASDAQ Capital Market or any other trading market for our Class A common stock.   

If so indicated in the applicable prospectus supplement, we will authorize underwriters or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in the prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in the prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will not be subject to any conditions except that:

• the purchase by an institution of the securities covered under that contract shall not at the time of delivery be prohibited under the laws of the jurisdiction to which that institution is subject; and 

• if the securities are also being sold to underwriters acting as principals for their own account, the underwriters shall have purchased such securities not sold for delayed delivery. The underwriters and other persons acting as our agents will not have any responsibility in respect of the validity or performance of delayed delivery contracts.

        Certain agents, underwriters and dealers, and their associates and affiliates may be customers of, have borrowing relationships with, engage in other transactions with, or perform services, including investment banking services, for us or one or more of our respective affiliates in the ordinary course of business.

        In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

        Under Rule 15c6-1 of the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. The applicable prospectus supplement may provide that the original issue date for your securities may be more than two scheduled business days after the trade date for your securities. Accordingly, in such a case, if you wish to trade securities on any date prior to the second business day before the original issue date for your securities, you will be required, by virtue of the fact that your securities initially are expected to settle in more than two scheduled business days after the trade date for your securities, to make alternative settlement arrangements to prevent a failed settlement.

        The securities may be new issues of securities and may have no established trading market. The securities may or may not be listed on a national securities exchange. We can make no assurance as to the liquidity of or the existence of trading markets for any of the securities.

        In compliance with the guidelines of the Financial Industry Regulatory Authority, which we refer to as “FINRA,” the aggregate maximum discount, commission or agency fees or other items constituting underwriting compensation to be received by any FINRA member or independent broker-dealer will not exceed 8% of the proceeds from any offering pursuant to this prospectus and any applicable prospectus supplement.
