(the "Company") will be held at the Company's headquarters at 901 Explorer Boulevard, Huntsville, Alabama, on Monday, April 27, 1998, at 10:30 a.m., local time, for the purposes of considering and voting upon: 1. A proposal to elect seven directors to serve until the 1999 Annual Meeting of Stockholders; 2. A proposal to ratify the appointment of Coopers & Lybrand L.L.P. as independent accountants of the Company for the fiscal year ending December 31, 1998; and 3. Such other business as properly may come before the Annual Meeting or any adjournments thereof. The Board of Directors is not aware of any other business to be presented to a vote of the stockholders at the Annual Meeting. Information relating to the above matters is set forth in the attached Proxy Statement. Stockholders of record at the close of business on March 12, 1998 are entitled to receive notice of and to vote at the Annual Meeting and any adjournments thereof. By Order of the Board of Directors. MARK C. SMITH Chairman of the Board and Chief Executive Officer Huntsville, Alabama March 19, 1998 PLEASE READ THE ATTACHED PROXY STATEMENT AND THEN PROMPTLY COMPLETE, EXECUTE AND RETURN THE ENCLOSED PROXY CARD IN THE ACCOMPANYING POSTAGE-PAID ENVELOPE. IF YOU ATTEND THE ANNUAL MEETING, YOU MAY REVOKE THE PROXY CARD AND VOTE IN PERSON IF YOU SO DESIRE. ADTRAN, Inc. 901 EXPLORER BOULEVARD HUNTSVILLE, ALABAMA 35806 PROXY STATEMENT FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD APRIL 27, 1998 This Proxy Statement is furnished to the stockholders of ADTRAN, Inc. (the "Company") in connection with the solicitation of proxies by the Board of Directors of the Company to be voted at the 1998 Annual Meeting of Stockholders and at any adjournments thereof (the "Annual Meeting"). The Annual Meeting will be held at the headquarters of the Company, 901 Explorer Boulevard, Huntsville, Alabama, on Monday, April 27, 1998, at 10:30 a.m., local time. The approximate date on which this Proxy Statement and form of proxy card are first being sent or given to stockholders is March 19, 1998. VOTING GENERAL The securities that can be voted at the Annual Meeting consist of Common Stock of the Company, $.01 par value per share, with each share entitling its owner to one vote on each matter submitted to the stockholders. The record date for determining the holders of Common Stock who are entitled to receive notice of and to vote at the Annual Meeting is March 12, 1998. On the record date, 39,402,679 shares of Common Stock were outstanding and eligible to be voted at the Annual Meeting. QUORUM AND VOTE REQUIRED The presence, in person or by proxy, of a majority of the outstanding shares of Common Stock of the Company is necessary to constitute a quorum at the Annual Meeting. In counting the votes to determine whether a quorum exists at the Annual Meeting, the proposal receiving the greatest number of all votes "for" or "against" and abstentions (including instructions to withhold authority to vote) will be used. In voting with regard to the proposal to elect directors (Proposal 1), stockholders may vote in favor of all nominees, withhold their votes as to all nominees or withhold their votes as to specific nominees. The vote required to approve Proposal 1 is governed by Delaware law and is a plurality of the votes cast by the holders of shares entitled to vote, provided a quorum is present. As a result, in accordance with Delaware law, votes that are withheld will be counted in determining whether a quorum is present but will have no other effect on the election of directors. 1 In voting with regard to the proposal to ratify the directors' appointment of independent accountants (Proposal 2), stockholders may vote in favor of the proposal or against the proposal or may abstain from voting. The votes required to approve Proposal 2 are governed by Delaware law and are the affirmative vote of the holders of a majority of the shares represented and entitled to vote at the Annual Meeting, provided a quorum is present. As a result, abstentions will be considered in determining whether a quorum is present and the number of votes required to obtain the necessary majority vote and therefore, will have the same legal effect as voting against the respective proposals. Under the rules of the New York and American Stock Exchanges (the "Exchanges") that govern most domestic stock brokerage firms, member firms that hold shares in street name for beneficial owners may, to the extent that such beneficial owners do not furnish voting instructions with respect to any or all proposals submitted for stockholder action, vote in their discretion upon proposals which are considered "discretionary" proposals under the rules of the Exchanges. Member brokerage firms that have received no instructions from their clients as to "non-discretionary" proposals do not have discretion to vote on these proposals. Although "broker non-votes" will be considered in determining whether a quorum exists at the Annual Meeting, "broker non-votes" will not be considered as votes cast in determining the outcome of any proposal. As of March 12, 1998 (the record date for the Annual Meeting), the directors and executive officers of the Company beneficially owned or controlled approximately 19,796,246 shares of Common Stock of the Company, constituting approximately 50.2% of the outstanding Common Stock. The Company believes that the holders of more than a majority of the Common Stock outstanding on the record date will vote all of their shares of Common Stock in favor of each of the two proposals and, therefore, that the presence of a quorum and the approval of the proposals is reasonably assured. PROXIES Stockholders should specify their choices with regard to each of the two proposals on the enclosed proxy card. All properly executed proxy cards delivered by stockholders to the Company in time to be voted at the Annual Meeting and not revoked will be voted at the Annual Meeting in accordance with the directions noted thereon. IN THE ABSENCE OF SUCH INSTRUCTIONS, THE SHARES REPRESENTED BY A SIGNED AND DATED PROXY CARD WILL BE VOTED "FOR" THE ELECTION OF ALL DIRECTOR NOMINEES AND "FOR" THE RATIFICATION OF THE APPOINTMENT OF INDEPENDENT ACCOUNTANTS. If any other matters properly come before the Annual Meeting, the persons named as proxies will vote upon such matters according to their judgment. Any stockholder delivering a proxy has the power to revoke it at any time before it is voted by giving written notice to Charlene Little, Assistant Secretary of the Company, at 901 Explorer Boulevard, Huntsville, Alabama 35806 (for overnight delivery) or at P.O. Box 140000, Huntsville, Alabama 35814-4000 (for mail delivery), by executing and delivering to Ms. Little a proxy card bearing a later date or by voting in person at the Annual Meeting; provided, however, that under the rules of the Exchanges, as followed by The Nasdaq Stock Market, Inc., any beneficial owner of the Company's Common Stock whose shares are held in street name by a member brokerage firm may revoke his proxy and vote his shares in person at the Annual Meeting only in accordance with applicable rules and procedures of the Exchanges, as employed by the beneficial owner=s brokerage firm. In addition to soliciting proxies through the mail, the Company may solicit proxies through its directors, officers and employees in person and by telephone or facsimile. Brokerage firms, nominees, 2 custodians and fiduciaries also may be requested to forward proxy materials to the beneficial owners of shares held of record by them. All expenses incurred in connection with the solicitation of proxies will be borne by the Company. SHARE OWNERSHIP OF PRINCIPAL STOCKHOLDERS AND MANAGEMENT The following table sets forth information regarding the beneficial ownership of the Company's Common Stock as of December 31, 1997, (i) by each person known to the Company to be the beneficial owner of more than 5% of the Company's Common Stock, (ii) each director of the Company, (iii) each of the executive officers of the Company named in the Summary Compensation Table herein and (iv) all directors and executive officers of the Company as a group, based in each case on information furnished to the Company by such persons.

Attendance at meetings of the 6 Board and its committees as a whole averaged 82%. No director attended less than 75% of the aggregate of meetings of the Board of Directors and meetings of the committees of which he is a member. The Audit Committee makes recommendations to the Board concerning the appointment of the Company's independent accountants; reviews with such accountants their audit plan, the scope and results of their audit engagement and the accompanying management letter, if any; reviews the scope and results of the Company's internal auditing procedures; consults with the independent accountants and management with regard to the Company's accounting methods and the adequacy of its internal accounting controls; approves professional services provided by the independent accountants; reviews the independence of the independent accountants; and reviews the range of the independent accountants' audit and non-audit fees. The Audit Committee is composed of William L. Marks and Roy J. Nichols.

The report specifically reviews the methods employed in setting the compensation of the Company's Chairman of the Board and Chief Executive Officer (the "Chief Executive Officer") and generally with respect to all executive officers. For 1997, the compensation of the Chief Executive Officer was established by the Board of Directors without any reference to quantitative measures of individual or Company performance but based instead solely on the Board's subjective evaluation of the performance of the Chief Executive Officer and the Company. The compensation paid to the Company's other executive officers for 1997 was established by the Chief Executive Officer in his discretion and was recommended by him to the Board of Directors for approval. Similar to the establishment of the Chief Executive Officer's compensation by the Board of Directors, the Chief Executive Officer based the compensation levels of the other executive officers not on any quantitative measures of individual or Company performance but upon his subjective evaluation of the performance of the individual executive officers and the Company. The Board of Directors approved the recommendations of the Chief Executive Officer with regard to the 1997 compensation of each of the other executive officers of the Company. In 1997, the Board of Directors established a bonus incentive compensation program (the "Bonus Program") for certain executive officers of the Company. Bonuses granted under the Bonus Program are determined by a formula based on targeted increases in per share after tax earnings of the Company from the end of a fiscal year to the end of the following fiscal year and are reflected in Table 1. 9 LIMITATIONS ON THE DEDUCTIBILITY OF EXECUTIVE COMPENSATION Pursuant to the Omnibus Budget Reconciliation Act of 1993, certain non- performance-based compensation in excess of $1,000,000 to executives of public companies is no longer deductible to these companies. Qualifying performance- based incentive compensation, however, would be both deductible and excluded for purposes of calculating the $1,000,000 compensation threshold. In this regard, the Compensation Committee must determine whether any actions with respect to this new limit should be taken by the Company. The Company=s executive compensation for 1997 did not exceed the legal limitations. The Compensation Committee will continue to monitor this situation and will take appropriate action if it is warranted in the future. Compensation Committee: O. Gene Gabbard, Williams L. Marks, Roy J. Nichols and James L. North. COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION James L. North, a partner in the law firm of James L. North & Associates, is a director of the Company and beneficially owns 139,000 shares of the Common Stock of the Company. The Company paid James L. North & Associates fees of $61,350 plus expenses of $2,958 for legal services rendered during 1997. All bills for services rendered by James L. North & Associates are reviewed and approved by the Company=s Vice President - Finance and Chief Financial Officer. Management believes that the fees for such services are comparable to those charged by other firms for services rendered to the Company. STOCK PERFORMANCE GRAPH The Company's Common Stock began trading on the Nasdaq National Market on August 9, 1994. The price information reflected for the Company's Common Stock in the following performance graph and accompanying table represents the closing sales prices of the Common Stock for the period from August 9, 1994 through December 31, 1997 on an annual basis. The graph and the accompanying table compare the cumulative total stockholders' return on the Company's Common Stock with the Nasdaq Telecommunications Index and the Nasdaq US Index. The calculations in the following graph and table assume that $100 was invested on August 9, 1994 in each of the Company's Common Stock, the Nasdaq Telecommunications Index and the Nasdaq US Index and also assume dividend reinvestment. The closing sale price of the Common Stock on the Nasdaq National Market was $28f per share on March 12, 1998. 10 COMPARISON OF CUMULATIVE TOTAL RETURN AMONG THE COMPANY, NASDAQ TELECOMMUNICATIONS INDEX AND NASDAQ US INDEX 8/9/94 12/31/94 12/31/95 12/31/96 12/31/97 - ------------------------------------------------------------------------------------- ADTRAN, Inc. $100 $254 $603 $461 $306 Nasdaq Telecommunications Index $100 $ 96 $126 $129 $191 Nasdaq US Index $100 $105 $148 $182 $224 11 SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and regulations of the Securities and Exchange Commission thereunder require the Company's directors, executive officers and persons who own more than 10% of the Company's Common Stock, as well as certain affiliates of such persons, to file initial reports of their ownership of the Company's Common Stock and subsequent reports of changes in such ownership with the Securities and Exchange Commission and the National Association of Securities Dealers, Inc. Directors, executive officers and persons owning more than 10% of the Company's Common Stock are required by Securities and Exchange Commission regulations to furnish the Company with copies of all Section 16(a) reports they file. Based solely on its review of the copies of such reports received by it, the Company believes that during the fiscal year ended December 31, 1997, its directors, executive officers and owners of more than 10% of its Common Stock complied with all applicable filing requirements, except that Forms 5 for each of Robert A. Fredrickson, Jude T. Panetta and Danny A. Windham were filed on February 24, 1998 which was 10 days after the deadline of February 14, 1998 for such filings. PROPOSAL 2 - RATIFICATION OF APPOINTMENT OF INDEPENDENT ACCOUNTANTS The Board of Directors of the Company, upon the recommendation of the Audit Committee, has appointed the firm of Coopers & Lybrand L.L.P. to serve as independent accountants of the Company for the fiscal year ending December 31, 1998, and has directed that such appointment be submitted to the stockholders of the Company for ratification at the Annual Meeting. Coopers & Lybrand L.L.P. has served as independent accountants of the Company since 1986 and is considered by management of the Company to be well qualified. If the stockholders do not ratify the appointment of Coopers & Lybrand L.L.P., the Board of Directors will reconsider the appointment. Representatives of Coopers & Lybrand L.L.P. will be present at the Annual Meeting and will have an opportunity to make a statement if they desire to do so.
