RISK FACTORS

Investing in our common stock involves certain risks, including the risks referred to or described below that relate to our business and to this offering and our common stock. You should carefully consider and evaluate these risks, as well as the other information included and incorporated by reference into this prospectus supplement and the accompanying base prospectus, before deciding whether to invest in shares of our common stock. Our business, results of operations or financial condition could be adversely affected by any of these risks or by additional risks and uncertainties not currently known to us or that we currently consider immaterial.

Risks Related to Our Business

Our business is influenced by many factors that are difficult to predict, involve uncertainties that may materially affect actual results and are often beyond our control. We have identified and will in the future identify a number of these factors under the heading “Risk Factors” in our Annual Reports on Form10-K, Quarterly Reports on Form10-Q and/or Current Reports on Form8-K, which are incorporated by reference into this prospectus supplement.

Risks Related to this Offering and Our Common Stock

The market price of our common stock may be adversely affected by the issuance and sale of our common stock, including pursuant to the sales agreement.

We are not restricted from issuing additional shares of our common stock or other equity-related securities. We cannot predict the effect that issuances or sales of our common stock, including pursuant to the sales agreement, may have on the market price for our common stock. The issuance and sale of substantial amounts of common stock or other equity-related securities could adversely affect the market price of our common stock.

The market price of our common stock may fluctuate significantly, and shares of our common stock may trade at prices below the price at which you purchased them.

The market price of our common stock may fluctuate significantly as a result of many factors, including, but not limited to:

• general economic or political conditions;

• volatility in the equity securities market;

• the operating and stock price performance of other companies that investors or analysts may deem comparable to us;

• changes in investors’ and analysts’ perception of our and/or our industry’s risk and return characteristics relative to other investment alternatives;

• differences between our actual financial and operating results and those expected by investors and analysts;

• adverse outcomes from litigation or regulatory or other governmental proceedings or investigations; and

• changes in regulation or tax law.

These factors, as well as those referred to under “Risks Related to Our Business” above and other factors relating to the market as a whole or our industry, may adversely affect the market price of our common stock, regardless, in some instances, of our actual operating performance. As a result, shares of our common stock may trade at prices significantly below the price paid by you to acquire shares of our common stock.

S-8

We may not be able to continue paying regular dividend payments, which could adversely affect the market price of our common stock.

Our ability to continue paying regular dividends is based on many factors, including the success of our operations, the demand for our services, our regulatory environment and the cost recovery and other rate mechanisms available to us and our liquidity needs. Many of these factors are beyond our control and a change in these factors could adversely impact our ability to continuing paying regular dividends. In addition, certain covenants on new or existing debt could, in certain circumstances, limit our ability to pay dividends. A failure by us to continue paying regular dividends could adversely affect the market price of our common stock.

Our common stock is an equity security and is subordinate to our existing and any future indebtedness.

Shares of our common stock are equity interests and, as such, rank junior to all of our current indebtedness as well as any indebtedness incurred by us in the future. Accordingly, in the event of a bankruptcy, liquidation or other similar proceeding, your rights as a holder of our common stock will be subordinate to the rights of the holders of our indebtedness and any othernon-equity claims against us.

Certain provisions in our organizational documents and under Virginia law may deter or delay an acquisition of us.

Certain provisions of the Virginia Stock Corporation Act and our articles of incorporation and bylaws may deter or delay certain transactions that our shareholders may otherwise consider to be in their best interest, including transactions that might result in our shareholders receiving a premium for their shares. See “Description of Common Stock” in the accompanying base prospectus and the material referred to therein for more information.

S-9

USE OF PROCEEDS

We intend to use the net proceeds from this offering to finance capital expenditures and for other general corporate purposes, including to reduce indebtedness or to fund future acquisitions of, or investments in, assets or businesses.

S-10

DESCRIPTION OF COMMON STOCK

We are authorized to issue 20,000,000 shares of common stock and 5,000,000 shares of preferred stock. As of March 5, 2020, no shares of preferred stock were outstanding. For a description of our common stock, see “Description of Common Stock” beginning on page 10 of the accompanying base prospectus.

S-11

PLAN OF DISTRIBUTION

We have entered into the sales agreement with the Sales Agent pursuant to which we may offer and sell from time to time shares of our common stock in an aggregate offering amount of up to $15,000,000. Sales under this prospectus supplement, if any, will be in “at the market” sales as defined in Rule 415 under the Securities Act, including, but not limited to, sales made directly on or through NASDAQ or sales made to or through a market maker or through an electronic communications network. In addition, the Sales Agent may purchase shares of our common stock for its own account as principal if expressly authorized to do so by us. The Sales Agent will not engage in any transactions that stabilize our common stock in connection with this offering.

From time to time during the term of the sales agreement, we will notify the Sales Agent of the amount of shares to be sold, the dates on which such sales are requested to be made, the minimum price below which sales may not be made and any limitation on the number of shares that may be sold in any one day. Once we have so notified the Sales Agent, unless the Sales Agent declines to accept such notice or until such notice is terminated or suspended by us as permitted by the sales agreement, the Sales Agent will use its commercially reasonable efforts consistent with its normal trading and sales practices to sell, on our behalf, such shares up to the amount specified in the notice and on such terms as are specified in the notice. The obligations of the Sales Agent under the sales agreement are subject to a number of customary conditions that we must meet, which the Sales Agent reserves the right to waive in its sole discretion. We or the Sales Agent may suspend the sale of shares under the sales agreement at any time upon providing notice to the other party of such suspension.

The Sales Agent will provide written confirmation to us no later than the opening of the trading day immediately following any trading day on which the Sales Agent has sold shares of common stock for us under the sales agreement. Each confirmation will include the number of shares sold on that day, the aggregate compensation payable by us to the Sales Agent in connection with the sales on that day and the net proceeds to us from such sales.

Settlement of sales under the sales agreement will occur on the second trading day following the date on which such sales are made, unless otherwise specified by us. Sales of our common stock under the sales agreement will be settled at The Depository Trust Company through its Deposit and Withdrawal at Custodian System or by such other means of delivery as we and the Sales Agent may mutually agree upon. There is no arrangement for funds to be received in an escrow, trust or similar arrangement.

We will pay the Sales Agent a commission equal to 2.5% of the gross sales price per share of our common stock that it sells under the sales agreement. The remaining sale proceeds, after deducting any transaction fees imposed on such sales, will equal our net proceeds for the sale of such shares under the sales agreement. We have agreed to reimburse the Sales Agent for certain of its legal and other expenses incurred in connection with this offering.

We will deliver copies of this prospectus supplement to NASDAQ or any other market on which shares are sold as may be required by the rules of such exchange or market. We will report at least quarterly, in respect of any quarter in which sales were made, the number of shares of our common stock sold by the Sales Agent under the sales agreement, the net proceeds received by us in connection with such sales and the gross compensation paid by us to the Sales Agent with respect to such sales.

In connection with the sale of shares of our common stock on our behalf under the sales agreement, the Sales Agent may be deemed to be an “underwriter” within the meaning of the Securities Act, and the compensation paid to the Sales Agent may be deemed to be underwriting commissions or discounts. We have agreed in the sales agreement to provide indemnification and contribution to the Sales Agent against certain civil liabilities, including liabilities under the Securities Act.

The offering of our common stock pursuant to the sales agreement will terminate upon the earlier of the sale of all shares of common stock subject to the sales agreement or the termination of the sales agreement by us or the Sales Agent in accordance with the terms of the sales agreement.

The Sales Agent may, from time to time in the future, engage in transactions with and perform services for us in the ordinary course of business.

S-12

Preferred Stock

We are authorized to issue 5,000,000 shares of preferred stock, no par value. As of January 31, 2020, no shares of preferred stock were outstanding.

authority to determine the number of shares of each series and the rights (which may include voting rights), preferences and limitations of each series. All series of our preferred stock would rank, with respect to dividends and liquidation rights, senior to our common stock. The future issuance of any series of preferred stock could also adversely impact the voting rights of the holders of our common stock.

Anti-Takeover Matters

Certain provisions of the Virginia Stock Corporation Act and our articles of incorporation and bylaws may have an anti-takeover effect and deter certain transactions that our shareholders may otherwise consider to be in their best interest, including transactions that might result in our shareholders receiving a premium for their shares. The provisions of this type in our articles and bylaws include, among others, those relating to our classified board of directors, our “blank check” preferred stock and the requirements for calling a special meeting of shareholders. The provisions of this type in the Virginia Stock Corporation Act include, among others, the affiliated transactions statute and the control share acquisitions statute. For a more detailed discussion of these provisions, see the description of our common stock contained in Exhibit 99.1 to Amendment No. 1 to Current Report on Form 8-K filed February 5, 2020, which is incorporated herein by reference.

We may sell the shares of common stock offered under this prospectus in any of the ways described below or in any way set forth in an applicable prospectus supplement:

• to or through underwriters, brokers or dealers;

• through one or more agents, including in an “at-the-market” offering within the meaning of Rule 415 under the Securities Act;

• directly to purchasers or to a single purchaser;

• through a block trade in which the broker or dealer engaged to handle the block trade will attempt to sell the shares 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 these methods of sale.

The distribution of shares of common stock offered under this prospectus 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.

We will set forth in a prospectus supplement the terms of a particular offering of shares of our common stock under this prospectus, including:

• the method of distribution of the shares being sold and any applicable restrictions;

• the name or names of any agents or underwriters;

• the purchase price of the securities being offered and the proceeds we will receive from the sale;

• any overallotment options under which underwriters may purchase additional shares of stock from us;

• any agency fees or underwriting discounts or other items constituting agents’ or underwriters’ compensation;

• any initial public offering price; and

• any discounts or concessions allowed or re-allowed or paid to dealers.

Underwriters may offer and sell the shares of common stock offered under this prospectus from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price, or at varying prices determined at the time of sale. The obligations of the underwriters to purchase the shares will be subject to the conditions set forth in an underwriting agreement between us and the underwriters. If underwriters are used in the sale of any shares, the shares will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions described above. The shares may be either offered to the public through underwriting syndicates represented by managing underwriters, or directly by underwriters. Generally, the underwriters’ obligations to purchase the shares will be subject to certain conditions precedent. The underwriters will be obligated to purchase all of the shares if they purchase any of the shares. We may use underwriters with whom we have a material relationship. We will describe in the prospectus supplement or a free writing prospectus, naming the underwriter, the nature of any such relationship.

Any offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

We may from time to time engage a firm to act as our agent for one or more offerings of our shares of common stock under this prospectus. We sometimes refer to this agent as our “offering agent.” If we reach agreement with an offering agent with respect to a specific offering, including the number of shares and any minimum price below which sales may not be made, then the offering agent will try to sell such shares on the agreed terms. The offering agent could make sales in privately negotiated transactions or using any other method permitted by law, including sales deemed to be through an “at the market” offering as defined in Rule 415 under the Securities Act, including sales made directly on the NASDAQ Global Market, or sales made to or through a market maker other than on an exchange. The offering agent will be deemed to be an “underwriter” within the meaning of the Securities Act with respect to any sales effected through an “at the market” offering.

Agents, underwriters and other third parties described above may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution from us with respect to payments that the agents, underwriters, or other third parties may be required to make in respect of these civil liabilities. Agents, underwriters, and such other third parties may be customers of, engage in transactions with or perform services for us in the ordinary course of business.

Certain underwriters may use the prospectus and any accompanying prospectus supplement for offers and sales related to market-making transactions in the shares of common stock. These underwriters may act as principal or agent in these transactions, and the sales will be made at prices related to prevailing market prices at the time of sale.

Certain persons participating in an offering may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with rules and regulations under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of shares in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the shares originally sold by the dealer are purchased in a short covering transaction to cover short positions. Those activities may cause the price of the shares to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.

To the extent permitted by and in accordance with Regulation M under the Exchange Act, any underwriters who are qualified market makers on the NASDAQ Global Market may engage in passive market making transactions in our shares of common stock on the NASDAQ Global Market during the business day prior to the pricing of an offering, before the commencement of offers or sales. Passive market makers must comply with applicable volume and price limitations and must be identified as passive market makers. In general, a passive market maker must display its bid at a price not in excess of the highest independent bid for such security; if all independent bids are lowered below the passive market maker’s bid, however, the passive market maker’s bid must then be lowered when certain purchase limits are exceeded.

We also may sell any of the shares of common stock offered under this prospectus through other agents designated by us from time to time. We will name any agent involved in the offer or sale of the shares and will list any commissions payable by us to these agents in the applicable prospectus supplement. These agents will be acting on a best efforts basis to solicit purchases for the period of their appointment, unless stated otherwise in the applicable prospectus supplements.
