Our principal executive offices are located at 520 Pike Street, Suite 2000, Seattle, Washington 98101 and our telephone number is (206) 331-3300.

RISK FACTORS

You should carefully consider the risks factors that are incorporated by reference in this prospectus from our Quarterly Report on Form 10-Q for the quarter ended September 30, 2020 as well as in our other SEC reports incorporated by reference before making an investment decision regarding our securities. In addition, the global economic climate and additional or unforeseen effects from the COVID-19 pandemic may amplify many of these risks. If any such risks actually occur, our business, financial condition and results of operations could be harmed. In that case, the trading price of our Class B common stock could decline and you could lose all or part of your investment. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations.

FORWARD LOOKING STATEMENTS

This prospectus, including the information incorporated by reference, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. All statements other than statements of historical facts contained in this prospectus, including statements regarding the benefits and risks associated with our acquisitions, our future operating results, financial position, and business strategy, expectations regarding our growth and the growth of the industry in which we operate, and plans and objectives of management for future operations, are forward-looking statements. The words “believe,” “may,” “estimate,” “continue,” “anticipate,” “intend,” “expect” and similar expressions, as they relate to us, are intended to identify forward-looking statements.

Any or all of our forward-looking statements in this prospectus may turn out to be inaccurate. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs. They may be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including the risks, uncertainties and assumptions described in “Risk Factors.” In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this prospectus may not occur as contemplated, and actual results could differ materially from those anticipated or implied by the forward-looking statements. In addition, the global economic climate and additional or unforeseen effects from the COVID-19 pandemic may amplify many of these risks.

You should not unduly rely on these forward-looking statements, which speak only as of the date of this prospectus. Unless required by law, we undertake no obligation to publicly update or revise any forward-looking statements to reflect new information or future events or otherwise. You should, however, review the factors and risks we describe in the reports we will file from time to time with the SEC after the date of this prospectus. See “Where You Can Find More Information.”

SELLING STOCKHOLDERS

We are registering for resale a total of up to 3,582,960 shares of Class B common stock issued or issuable to the selling stockholders. When we refer to the “selling stockholders” in this prospectus, we include any pledgees, donees, assignees, transferees, successors and others who may hold any of the selling stockholder’s interest.

The selling stockholders will acquire such shares on specified dates pursuant to the terms of (i) that certain Share Purchase Agreement, dated as of November 20, 2018, by and among Marchex, Inc, Sita Laboratories, Inc., the sellers named therein and the stockholder representative named therein, and, (ii) that certain Equity Purchase Agreement, dated as of December 13, 2019, by and among Marchex, Inc., Sonar Technologies, Inc., the sellers identified therein and Fortis Advisors LLC, as Securityholder Representative (collectively, the “Purchase Agreements”) as applicable. For more information about the Purchase Agreements, see our Annual Report on Form 10-K for the year ended December 31, 2019 incorporated by reference into this prospectus.

The table below sets forth, to the Company’s knowledge, the following information regarding the selling stockholders as of November 18, 2020:

The information regarding the selling stockholders may change from time to time. If required, we will describe these changes in one or more prospectus supplements.

PLAN OF DISTRIBUTION

The selling stockholders may use this prospectus to sell the shares at any time while the prospectus is in effect, unless we have notified the selling stockholders that the prospectus is not available at that particular time. The selling stockholders will determine if, when and how it will sell the shares it owns. Any sales may occur in one or more of the following types of transactions (including block transactions):

These transactions may involve the transfer of the shares upon exercise or settlement of put or call options, or the delivery of the shares to replace shares that were previously borrowed from another stockholder or a combination of such methods. If a broker-dealer is used in the sale of shares, that person may solicit potential purchasers. The shares may also be transferred as a gift or as a result of a pledge, or may be sold to a broker-dealer acting as principal. These persons may then sell the shares to another person, either directly or through another broker-dealer, subject to compliance with the requirements of the Securities Act.

The price at which sales of the shares occur may be based on market prices or may be negotiated between the parties, and the consideration may be cash or another form negotiated between the parties. Broker-dealers acting as agents or principals may be paid compensation in the form of discounts, concessions or commissions from the selling stockholders and/or from the purchasers of the shares, or both. Brokers or dealers may be deemed to be “underwriters” within the meaning of the Securities Act. Any profits on the resale of shares by a broker-dealer acting as principal might be deemed to be underwriting discounts or commissions under the Securities Act. Discounts, concessions, commissions and similar selling expenses, if any, that can be attributed to the sale of shares will be paid by the selling stockholders and/or the purchasers. We have agreed to pay certain of the costs, expenses and fees of preparing, filing and maintaining this prospectus and the registration statement of which this prospectus is a part, but we will not receive any proceeds from sale of these shares. The selling stockholders may agree to indemnify any agent, dealer or broker-dealer that participates in transactions involving sales of the shares if liabilities are imposed on it under the Securities Act.

The selling stockholders have advised us that he, she or it has not entered into any agreements, understandings or arrangements with any underwriters or broker-dealers regarding the sale of such shares, nor is there an underwriter or coordinating broker acting in connection with a proposed sale of shares by any selling stockholder. If we are notified by any selling stockholder that any material arrangement has been entered into with a broker-dealer for the sale of shares, if required, we will file a supplement to this prospectus. If the selling stockholders use this prospectus for any sale of the shares, they will be subject to the prospectus delivery requirements of the Securities Act. The anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of our Class B common stock and activities of the selling stockholders.

We will use commercially reasonable best efforts to maintain the effectiveness of the registration statement with respect to the shares of Class B common stock offered hereunder by the selling stockholders for a period of six months from the date of the last acquisition of shares by the selling stockholders pursuant to the Purchase Agreements (plus the aggregate number of days, if any, during which sales may be suspended while the suspension right is in effect).

LEGAL MATTERS

Certain legal matters with respect to the shares of Class B common stock offered hereby will be passed upon for us by Michelle Paterniti, General Counsel and Secretary of Marchex. Ms. Paterniti owns, or has the right to acquire, a number of shares of Marchex’s Class B common stock which represents less than 0.1% of Marchex’s outstanding Class B common stock.

DISCLOSURE OF COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy and is therefore unenforceable.

PART II. INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth all expenses payable by us in connection with the offering of our Class B common stock being registered hereby. All amounts are estimated except the SEC registration fee.

The certificate of incorporation and the by-laws of the registrant provide that the registrant shall indemnify its officers, directors and certain others to the maximum extent permitted by the General Corporation Law of the State of Delaware.

Section 145 of the General Corporation Law of the State of Delaware provides in relevant part as follows:

(a) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative) other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding had no reasonable cause to believe the person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

(b) A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interest of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

The General Corporation Law does not allow for the elimination or limitation of liability of a director: (1) for any breach of a director’s duty of loyalty to the corporation or its stockholders; (2) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (3) arising under Section 174 thereof; or (4) for any transaction from which the director derived an improper personal benefit. The General Corporation Law provides further that the indemnification permitted thereunder shall not be deemed exclusive of any rights to which the directors and officers may be entitled under the corporation’s bylaws, any agreement, a vote of stockholders or otherwise.

In addition, pursuant to our certificate of incorporation and by-laws, we shall indemnify our directors and officers against expenses (including judgments or amounts paid in settlement) incurred in any action, civil or criminal, to which any such person is a party by reason of any alleged act or failure to act in his capacity as such, except as to a matter as to which such director or officer shall have been finally adjudged not to have acted in good faith in the reasonable belief that his action was in the best interest of the corporation.

We maintain directors and officers liability insurance for the benefit of our directors and certain of our officers.

We have entered into indemnification agreements with each of our directors and our executive officers.

Please see the exhibit index which precedes the signature page of this registration statement.

II-1

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report, pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Exchange Act and will be governed by the final adjudication of such issue.
