We are party to a Shareholders Agreement, dated as of October 31, 2011, among us, Quadrangle Capital Partners LP, Quadrangle Select Partners LP, Quadrangle Capital Partners-A LP, Quadrangle NTELOS Holdings II LP (together with Quadrangle Capital Partners LP, Quadrangle Select Partners LP and Quadrangle Capital Partners-A LP, the “Quadrangle Entities”) and the management shareholders named therein, or the Shareholders Agreement. Pursuant to our Shareholders Agreement, we have agreed to register shares of our common stock received by the Quadrangle Entities. The Quadrangle Entities have now requested that we register all of their shares under the Securities Act of 1933, as amended (the “Securities Act”). Upon this request from the Quadrangle Entities, we were obligated to prepare and file a registration statement covering the shares held by them. This prospectus is filed to comply with these registration obligations. See “Certain Relationships and Transactions.”

The following table sets forth information known to us with respect to the beneficial ownership of our common stock as of August 23, 2013 by the selling stockholders and their affiliates.

We have determined the number and percentage of shares beneficially owned in accordance with Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and this information does not necessarily indicate beneficial ownership for any other purpose. In determining the number of shares beneficially owned by the selling stockholders and the percentage ownership of the selling stockholders, we included any shares as to which the selling stockholders has sole or shared voting power or investment power. Under the rules of the SEC more than one person may be deemed a beneficial owner of the same securities. Percentage of shares beneficially owned is based on 22,001,685 shares of common stock outstanding.

Our board of directors currently consists of eight members. Pursuant to the terms of our Shareholders Agreement, the Quadrangle Entities currently have the right to nominate three directors. One of the three directors designated by the Quadrangle Entities currently must be “independent” as defined by the rules of The NASDAQ Stock Market. Pursuant to the Shareholders Agreement, the Quadrangle Entities may designate only two directors, who do not need to be “independent,” if

their ownership falls below 20% of the voting power of our common stock, one director, who does not need to be “independent,” if their ownership falls below 10% and no directors if their ownership falls below 5%. The Shareholders Agreement also provides that one director will be our Chief Executive Officer for so long as he or she is employed by us. In accordance with the Shareholders Agreement, the Quadrangle Entities and the other management shareholders party thereto each are required to vote for such nominees and take all other necessary action to ensure that these nominees are elected to the Board of Directors.

In accordance with the Shareholders Agreement, we may not take certain significant actions, such as a merger or sale of assets in excess of $3 million, incurrences of indebtedness, amendments of organizational documents and certain other matters, subject to certain specified exceptions, without the approval of a majority of the members of the board of directors. The required quorum for any meeting of the board of directors must include at least one director designated by, and affiliated with, the Quadrangle Entities, for as long as the Quadrangle Entities are entitled to designate one or more members of the board of directors in accordance with the terms of the Shareholders Agreement.

The Shareholders Agreement covers other matters of corporate governance, restrictions on transfer of our securities, registration rights and information rights.

The selling stockholders currently intend to offer and sell pursuant to one or more prospectus supplements, from time to time, the securities offered by this prospectus, in one or more underwritten or other public offerings and at prices and on terms that will be determined at the time of the offering. The selling stockholders initially acquired their shares of our common stock in private placement transactions completed prior to the date of this prospectus. We will pay for all costs, expenses and fees in connection with the registration of the securities. In addition, we have agreed to indemnify the selling stockholders against certain liabilities in connection with offerings of the shares of common stock. The selling stockholders will pay for all selling discounts and commissions, if any, on the shares of stock offered by them.

However, the selling stockholders also may offer and sell securities, as applicable:

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

Offers to purchase our securities may be solicited by agents designated by the selling stockholders from time to time. Any agent involved in the offer or sale of our securities will be named, and any commissions payable by us and/or the selling stockholders to the agent will be described, in the applicable prospectus supplement. Unless otherwise indicated in the applicable prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment. Any agent may be deemed to be an underwriter, as such term is defined in the Securities Act, of the securities so offered and sold.

The selling stockholders may transfer their shares of common stock in ways not involving market makers or established trading markets, including directly by gift, distribution, or other transfer. The selling stockholders may also sell any shares of common stock that qualify for sale pursuant to Rule 144.

If the selling stockholders offer and sell our securities through an underwriter or underwriters, we and/or the selling stockholders will execute an underwriting agreement with the underwriter or underwriters. The names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transactions, including compensation of the underwriters and dealers, which may be in the form of discounts, concessions or commissions, if any, will be described in the applicable prospectus supplement, which, along with this prospectus, will be used by the underwriters to make resales of our securities. If underwriters are used in the sale of any of our securities in connection with this prospectus, those securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including negotiated transactions, at fixed public offering prices or at varying prices determined by the underwriters and us and/or the selling stockholders at the time of sale. Our securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by one or more underwriters, If any underwriter or underwriters are used in the sale of our securities, unless otherwise indicated in a related prospectus supplement, the underwriting agreement will provide that the obligations of the underwriters are subject to some conditions precedent and that with respect to a sale of our securities the underwriters will be obligated to purchase all such securities if any are purchased.

If any underwriters are involved in the offer and sale of our securities, they will be permitted to engage in transactions that maintain or otherwise affect the price of such securities or other securities of ours, These transactions may include over-allotment transactions, purchase to cover short positions created by an underwriter in connection with the offering and the imposition of penalty bids. If an underwriter creates a short position in the securities in connection with the offering, i.e., if it sells more securities than set forth on the cover page of the applicable prospectus supplement, the underwriter may reduce that short position by purchasing securities in the open market. In general, purchases of securities to reduce a short position could cause the price of the securities to be higher than it might be in the absence of such purchases. As noted above,

underwriters may also choose to impose penalty bids on other underwriters and/or selling group members. This means that if underwriters purchase securities on the open market to reduce their short position or to stabilize the price of the securities, they may reclaim the amount of the selling concession from those underwriters and/or selling group members who sold such securities as part of the offering.

If the selling stockholders offer and sell our securities through a dealer, the selling stockholders or an underwriter will sell our securities to the dealer, as principal. The dealer may then resell our securities to the public at varying prices to be determined by the dealer at the time of resale. Any such dealer may be deemed to be an underwriter, as such term is defined in the Securities Act, of our securities so offered and sold. The name of the dealer and the terms of the transactions will be set forth in the applicable prospectus supplement.

The selling stockholders may solicit offers to purchase our securities directly and the selling stockholders may sell our securities directly to institutional or other investors, who may be deemed to be an underwriter within the meaning of the Securities Act with respect to any resales of those securities. The terms of these sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

We and/or the selling stockholders may enter into agreements with agents, underwriters and dealers under which we may agree to indemnify the agents, underwriters and dealers against certain liabilities, including liabilities under the Securities Act, or to contribute to payments they may be required to make with respect to these liabilities. The terms and conditions of this indemnification or contribution will be described in the applicable prospectus supplement.

Some of the agents, underwriters or dealers or their affiliates may be customers of, engage in transactions with or perform services for us, the selling stockholders or any of our or their affiliates in the ordinary course of business.

The selling stockholders may authorize our respective agents or underwriters to solicit offers to purchase our securities at the public offering price under delayed delivery contracts. The terms of these delayed delivery contracts, including when payment for and delivery of our securities sold will be made under the contracts and any conditions to each party’s performance set forth in the contracts, will be described in the applicable prospectus supplement. The compensation received by underwriters or agents soliciting purchases of our securities under delayed delivery contracts will also be described in the applicable prospectus supplement.

The selling stockholders may be deemed to be underwriters within the meaning of Section 2(11) of the Securities Act. Any profit they realize on the resale of our common stock may be deemed to be underwriting discounts and commissions under the Securities Act. Neither we nor any selling stockholder can presently estimate the amount of any such compensation.

From time to time, the selling stockholders may pledge or grant a security interest in some or all of our shares of common stock owned by them. If the selling stockholders default in the performance of their secured obligations, the pledgees or secured parties may offer and sell such common stock from time to time by this prospectus. The selling stockholders also may transfer, distribute or donate our common stock owned by them in other circumstances. The number of shares of our common stock beneficially owned by selling stockholders will decrease as and when the selling stockholders transfer, distribute or donate their shares of our common stock or default in performing obligations secured by their shares of our common stock. The plan of distribution for the securities offered and sold under this prospectus will otherwise remain unchanged, except that the transferees, distributees, donees, pledgees, other secured parties or other successors in interest will be the selling stockholders for purposes of this prospectus.

Any underwriters who are qualified market makers on the NASDAQ Global Market may engage in passive market making transactions in the common stock on the NASDAQ Global Market in accordance with Rule 103 of Regulation M, during the business day prior to the pricing of the offering, and before the commencement of offers or sales of the common stock. 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 are authorized to issue 55,000,000 shares of common stock, par value $0.01 per share. All of our existing common stock is validly issued, fully paid and nonassessable. The discussion set forth below describes the most important terms of our common stock, restated certificate of incorporation and by-laws. 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 by-laws, which are filed as exhibits to the registration statement of which this prospectus is a part, and to the applicable provisions of the Delaware General Corporation law.

Set forth below is a brief discussion of the principal terms of our common stock:

Holders of our common stock are entitled to receive ratably dividends, if, as and when dividends are declared from time to time by our board of directors out of funds legally available for that purpose, after any dividends required to be paid on outstanding preferred stock, if any. The terms of our credit facility impose restrictions on our ability to declare dividends on our capital stock.

Each outstanding share of our common stock is entitled to one vote on all matters submitted to a vote of holders of our common stock. The holders of common stock do not have cumulative voting rights in the election of directors.

Our common stock will not be entitled to preemptive or other similar subscription rights to purchase any of our securities.

Upon our liquidation, dissolution or winding up, the holders of our common stock will be entitled to receive pro rata our assets which are legally available for distribution, after payment of all debts and other liabilities and subject to the prior rights of any holders of preferred stock then outstanding.

Our common stock is traded on the NASDAQ Global Market under the symbol “LMOS.”

We are a party to a Shareholders Agreement with the Quadrangle Entities. For a description of the Shareholders Agreement, see “Selling Stockholders — Certain Relationships and Transactions.” This description is qualified by reference to the Shareholders Agreement which is filed as an exhibit to the registration statement of which this prospectus is a part and incorporated by reference herein.

Our certificate of incorporation and by-laws contain certain provisions that are intended to enhance the likelihood of continuity and stability in the composition of the board of directors and which may have the effect of delaying, deferring or preventing a future takeover or change in control of the company unless such takeover or change in control is approved by the board of directors, including:

Our certificate of incorporation provides that all corporate powers will be exercised by our board of directors, except as otherwise specifically required by law or otherwise provided in our certificate of incorporation. Our certificate of incorporation and our bylaws do not permit stockholder action by written consent. Any action required or permitted to be taken by our stockholders must be effected at an annual or special meeting of stockholders and may not be effected by the written consent of our stockholders.

Pursuant to the General Corporation Law of the State of Delaware, or DGCL, a special meeting of stockholders may be called by the board of directors or by any other person authorized to do so in our certificate of incorporation or bylaws. Our bylaws provide that a stockholder may request a special meeting of stockholders subject to the conditions set forth in our bylaws, including that stockholders representing at least 25% of the total number of shares of stock entitled to vote on the matter or matters to be brought before the proposed special meeting request the special meeting of stockholders and that stockholders follow the procedures set forth in our bylaws.

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 shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws, or (iv) any action asserting a claim governed by the internal affairs doctrine. Our certificate of incorporation further provides that any person or entity purchasing or acquiring any interest in shares of our capital stock shall be deemed to have notice of and to have consented to the provisions described above.

Our by-laws establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to the board of directors. Stockholders at an annual meeting will only be able to consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of the board of directors or by a stockholder who was a stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has given our Secretary timely written notice, in proper form, of the stockholder’s intention to bring that business before the meeting. Although the by-laws do not give the board of directors the power to approve or disapprove stockholder nominations of candidates or proposals regarding other business to be conducted at a special or annual meeting, the by-laws may have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or may discourage or defer a potential acquirer from conducting a solicitation of proxies to elect its own slate of directors or otherwise attempting to obtain control of the company.

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless our certificate of incorporation provides otherwise. Our certificate of incorporation expressly provides that no stockholder shall be entitled to cumulate votes in the election of directors.

Our authorized but unissued shares of common stock and preferred stock will be available for future issuance without stockholder approval. These additional shares may be utilized for a variety of corporate purposes, including future public offerings to raise additional capital, corporate acquisitions and employee benefit plans. The existence of authorized but unissued shares of common stock and preferred stock could render more difficult or discourage an attempt to obtain control of a majority of our common stock by means of a proxy contest, tender offer, merger or otherwise.

An itemized statement of all expenses in connection with the issuance and distribution of the securities to be registered is set forth in the following table. (All amounts shown are estimates except for the Commission registration fee.)

The Registrant is incorporated under the laws of the State of Delaware. Section 145 (“Section 145”) of the General Corporation Law of the State of Delaware, as the same exists or may hereafter be amended (the “DGCL”), provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made, parties 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 such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. A Delaware corporation may indemnify any persons who are, were or are threatened to be made, a party to any threatened, pending or completed action or suit by or in the right of the corporation by reasons of the fact that such person was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity for such action or suit by or in the right of the corporation may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, provided further that no indemnification is permitted without judicial approval if the officer, director, employee or agent is adjudged to be liable to the corporation. Where an officer, director, employee or agent is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who 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 or enterprise, against any liability asserted against him and incurred by him in any such capacity, arising out of his status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

Section 102(b)(7) of the DGCL permits a corporation to include in its certificate of incorporation a provision eliminating or limiting the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that such provision shall not eliminate or limit the liability of a director (i) for any breach of the directors’ duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL (relating to unlawful payment of dividends and unlawful stock purchase and redemption) or (iv) for any transaction from which the director derived an improper personal benefit.

The Registrant’s certificate of incorporation provides that to the fullest extent permitted by the DGCL and except as otherwise provided in its by-laws, none of the Registrant’s directors shall be liable to it or its stockholders for monetary damages for a breach of fiduciary duty. In addition, the Registrant’s certificate of incorporation provides for indemnification of any person who was or is made or threatened to be made a party to any action, suit or other proceeding, whether criminal, civil, administrative or investigative, because of his or her status as a director, or officer of the Registrant, or service as a

director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise at the request of the Registrant to the fullest extent authorized under the DGCL against all expenses, liabilities and losses reasonably incurred by such person. Further, all of the directors and officers of the Registrant are covered by insurance policies maintained and held in effect by the Registrants against certain liabilities for actions taken in their capacities as such, including liabilities under the Securities Act.

The list of exhibits set forth in the Exhibit Index to this Registration Statement is incorporated herein by reference.

(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 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 Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;

(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 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:

(i) 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; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) 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.

(7) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and 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 Act and will be governed by the final adjudication of such issue.

(8) That, for purposes of determining any liability under the Securities Act of 1933:

(i) The information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective; and

(ii) Each post-effective amendment that contains a form of prospectus 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.

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Waynesboro, State of Virginia, on this 26^th day of August, 2013.
