Item 1.01. Entry into a Material Definitive Agreement.

Business Combination Agreement

On August 30, 2021, ADTRAN, Inc., a Delaware corporation (“ADTRAN”), and ADVA Optical Networking SE, a European stock corporation incorporated under the laws of the European Union and Germany (“ADVA”), entered into a business combination agreement (the “Business Combination Agreement”), pursuant to which both companies agreed to combine their respective businesses and each become subsidiaries of a new holding company, Acorn HoldCo, Inc., a Delaware corporation and currently a wholly-owned direct subsidiary of ADTRAN (“Acorn HoldCo”).

Under the terms of the Business Combination Agreement, Acorn MergeCo, Inc., a newly formed Delaware corporation and wholly-owned direct subsidiary of Acorn HoldCo (“Merger Sub”), will merge with and into ADTRAN, with ADTRAN surviving the merger (the “Merger”) as a wholly-owned direct subsidiary of Acorn HoldCo (the “surviving corporation”). Pursuant to the Merger, each outstanding share of common stock of ADTRAN will be converted into the right to receive one share of common stock of Acorn HoldCo. Acorn HoldCo will also make a public exchange offer to exchange each issued and outstanding no-par value bearer share of ADVA, pursuant to which each ADVA share tendered and accepted for exchange will be exchanged for 0.8244 shares of common stock of Acorn HoldCo (the “Exchange Offer”, and together with the Merger, the “Business Combination”). Upon completion of the Business Combination, and assuming that all of the outstanding ADVA shares are exchanged in the Exchange Offer, former ADTRAN stockholders and former ADVA shareholders will own approximately 54% and 46%, respectively, of the outstanding Acorn HoldCo shares.

Acorn HoldCo will apply to admit its shares to listing and trading on The NASDAQ Global Select Market (“NASDAQ”) and will apply to admit its shares to listing and trading on the regulated market (Regulierter Markt) of the Frankfurt Stock Exchange and the sub-segment thereof with additional post-admission obligations (Prime Standard) (trading in euros).

The Business Combination Agreement was unanimously approved by the Board of Directors of ADTRAN and by the supervisory board and management board of ADVA. The consummation of the Business Combination is subject to customary closing conditions, including, among others, (i) adoption of the Business Combination Agreement by holders of a majority of the outstanding shares of ADTRAN common stock, (ii) the tender in the Exchange Offer of at least 70% of the outstanding ADVA shares, (iii) the declaration of effectiveness by the U.S. Securities and Exchange Commission (“SEC”) of a registration statement on Form S-4 for the Acorn HoldCo shares to be issued in the Merger and the Exchange Offer, with no stop order in effect or being sought with respect thereto, (iv) receipt of certain antitrust and foreign direct investment regulatory approvals for the transaction (the “regulatory condition”) and (vi) the absence of any law, regulation, administrative act, injunction, temporary restraining order or preliminary or permanent injunction or other order issued by any governmental entity in any relevant jurisdiction prohibiting or making illegal (a) the consummation of the Exchange Offer or the Merger or (b) the ownership of ADVA shares or shares of the surviving corporation by Acorn HoldCo.

ADTRAN’s obligation to consummate the Business Combination is also subject to certain additional customary conditions, including (i) the absence of a Target Material Adverse Change for ADVA, as defined in the Business Combination Agreement, (ii) the absence of the violation of law by ADVA related to bribery, corruption or export sanctions, (iii) the absence of an increase or decrease in ADVA’s share capital of more than 1%, subject to certain exceptions and the absence of a loss in the amount of half or more of ADVA’s share capital and (iv) the absence of any insolvency proceedings against ADVA or circumstances requiring the opening of insolvency proceedings. Except for the regulatory condition, all conditions to the Business Combination must be satisfied on or prior to the end of the acceptance period for the Exchange Offer. The regulatory condition may remain outstanding for up to twelve months following the end of the acceptance period.

Each of ADTRAN and ADVA has agreed to various customary covenants and agreements, including covenants by ADTRAN and ADVA to conduct their respective businesses in the ordinary course consistent with past practice during the period between the execution of the Business Combination Agreement and the closing of the Business Combination and not to engage in certain kinds of transactions during this period. ADVA has also agreed to a non-solicitation covenant restricting its ability to solicit or enter into discussions or negotiations concerning proposals relating to alternative business combination transactions (subject to certain negotiated exceptions detailed in the Business Combination Agreement).

The Business Combination Agreement may be terminated by each of ADTRAN and ADVA under certain circumstances, including if (i) the Exchange Offer lapses as a result of non-satisfaction of the conditions to the Exchange Offer, (ii) the Exchange Offer is not settled by the date that is twelve months following the end of the acceptance period or (iii) the other party violates its material obligations under the Business Combination Agreement and the violation is not cured within thirty business days following notice thereof. The Business Combination Agreement provides for customary termination rights for ADVA, including if (i) the consideration offered in the Exchange Offer is lower than the amount agreed to in the Business Combination Agreement, (ii) the Exchange Offer contains closing conditions that differ (in anything other than de minimis respects) from the closing conditions specified in the Business Combination Agreement, (iii) ADTRAN’s intentions with respect to the strategy of ADTRAN in the approved Exchange Offer document are materially different than those set forth in the Business Combination Agreement or (iv) a superior offer (as defined in the Business Combination Agreement) has been published by a third party, Acorn HoldCo does not match the terms of such offer within ten business days and the management board and supervisory board of ADVA are entitled to support the superior offer under the provisions in the Business Combination Agreement. The Business Combination Agreement also provides for customary termination rights for ADTRAN, including if (i) the management board and/or supervisory board of ADVA does not recommend that the shareholders of ADVA accept the Exchange Offer in its reasoned statement supporting the Exchange Offer, withdraws such statement or amends such statement in a way that could adversely affect the consummation of the Exchange Offer, (ii) a superior offer has been settled or (iii) between the date of the Business Combination Agreement and the publication of the Exchange Offer document, there occurs a Target Material Adverse Change for ADVA, as defined in the Business Combination Agreement, or there is a violation of law by ADVA related to bribery, corruption or export sanctions.

The Business Combination Agreement also provides that following the consummation of the Business Combination, Acorn HoldCo’s board of directors will consist of nine members, including six members of the current ADTRAN board of directors, Thomas Stanton, H. Fenwick Huss, Gregory J. McCray, Balan Nair, Jacqueline H. Rice and Kathryn A. Walker, and three directors designated for appointment by ADVA, Brian Protiva, chief executive officer of ADVA, Nikos Theodosopoulos, chairman of ADVA’s supervisory board and Johanna Hey, vice chairwoman of ADVA’s supervisory board. Mr. Protiva will also be the executive vice chairman of the board of directors of Acorn HoldCo. Thomas Stanton, ADTRAN’s chairman and chief executive officer, will be the chairman and chief executive officer of Acorn HoldCo, and Michael Foliano, ADTRAN’s chief financial officer, will be the chief financial officer of Acorn HoldCo. At the closing of the Business Combination, Acorn HoldCo will appoint Christoph Glingener, ADVA’s chief technology officer, as chief technical officer of Acorn HoldCo. Following the consummation of the business combination, the name of Acorn HoldCo will be changed to “ADTRAN Holdings, Inc.”

The foregoing description of the Business Combination Agreement does not purport to be complete and is qualified in its entirety by reference to the Business Combination Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Irrevocable Undertaking

Acorn HoldCo has received an irrevocable undertaking (the “Irrevocable Undertaking”) from EGORA Holding GmbH and Egora Investments GmbH (collectively, the “Supporting Shareholders”) to validly accept the Exchange Offer with respect to 7,000,000 shares held by them (the “Relevant Shares”), representing 13.7% of the share capital of ADVA. The Irrevocable Undertaking includes other customary provisions, including certain restrictions on the Supporting Shareholders from disposing of the Relevant Shares.

The foregoing description of the Irrevocable Undertaking does not purport to be complete and is qualified in its entirety by reference to the Irrevocable Undertaking, a copy of which is filed as Exhibit 2.2 to this Current Report on Form 8-K and is incorporated herein by reference.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K 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. You can generally identify forward-looking statements by the use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “explore,” “evaluate,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” or “will,” or the negative thereof or other variations thereon or comparable terminology. These forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond ADTRAN’s and ADVA’s control.

These forward-looking statements include, but are not limited to, statements regarding benefits of the proposed Business Combination, integration plans and expected synergies, and anticipated future growth, financial and operating performance and results. Forward-looking statements involve risks and uncertainties that may cause actual results to be materially different from the results predicted or expected. No assurance can be given that these forward-looking statements will prove accurate and correct, or that projected or anticipated future results will be achieved. Factors that could cause actual results to differ materially from those indicated in any forward-looking statement include, but are not limited to: the expected timing and likelihood of the completion of the contemplated Business Combination, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the contemplated Business Combination that could reduce anticipated benefits or cause the parties to abandon the transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the Business Combination Agreement; the ability to successfully complete the proposed Business Combination; regulatory or other limitations imposed as a result of the proposed Business Combination; the success of the business following the proposed Business Combination; the ability to successfully integrate the ADTRAN and ADVA businesses; the possibility that ADTRAN stockholders may not approve the Business Combination Agreement or that the requisite number of ADVA shares may not be tendered in the public exchange offer; the risk that the parties may not be able to satisfy the conditions to closing of the proposed Business Combination in a timely manner or at all; risks related to disruption of management time from ongoing business operations due to the proposed Business Combination; the risk that the announcement or consummation of the proposed Business Combination could have adverse effects on the market price of ADTRAN’s common stock or ADVA’s common shares or the ability of ADTRAN and ADVA to retain customers, retain or hire key personnel, maintain relationships with their respective suppliers and customers, and on their operating results and businesses generally; the risk that Acorn HoldCo may be unable to achieve expected synergies or that it may take longer or be more costly than expected to achieve those synergies; the risk of fluctuations in revenue due to lengthy sales and approval process required by major and other service providers for new products; the risk posed by potential breaches of information systems and cyber-attacks; the risks that ADTRAN, ADVA or the post-combination company may not be able to effectively compete, including through product improvements and development; and such other factors as are set forth in ADVA’s annual and interim financial reports made publicly available and ADTRAN’s and Acorn HoldCo’s public filings made with the SEC from time to time, including but not limited to those described under the headings “Risk Factors” and “Forward-Looking Statements” in ADTRAN’s Form 10-K for the fiscal year ended December 31, 2020 and ADTRAN’s Form 10-Q for the quarterly period ended June 30, 2021, which are available via the SEC’s website at www.sec.gov. The foregoing list of risk factors is not exhaustive. These risks, as well as other risks associated with the contemplated Business Combination, will be more fully discussed in the proxy statement/prospectus and the offering prospectus that will be included in the Registration Statement on Form S-4 that will be filed with the SEC and in an offering document and/or any prospectuses or supplements to be filed with BaFin in connection with the contemplated Business Combination. In light of these risks, uncertainties and assumptions, the events described in the forward-looking statements might not occur or might occur to a different extent or at a different time than ADTRAN, ADVA or Acorn HoldCo has described. All such factors are difficult to predict and beyond our control. All forward-looking statements included in this document are based upon information available to ADTRAN, ADVA and Acorn HoldCo on the date hereof, and each of ADTRAN, ADVA and Acorn HoldCo disclaims and does not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

It should also be noted that projected financial information for the combined businesses of ADTRAN and ADVA is based on management’s estimates, assumptions and projections and has not been prepared in conformance with the applicable accounting requirements of Regulation S-X relating to pro forma financial information, and the required pro forma adjustments have not been applied and are not reflected therein. None of this information should be considered in isolation from, or as a substitute for, the historical financial statements of ADTRAN or ADVA. Important risk factors could cause actual future results and other future events to differ materially from those currently estimated by management, including, but not limited to, the risks that: a condition to the closing of the proposed Business Combination may not be satisfied; a regulatory approval that may be required for the proposed Business Combination is delayed, is not obtained or is obtained subject to conditions that are not anticipated; ADTRAN is unable to achieve the synergies and value creation contemplated by the proposed Business Combination; ADTRAN is unable to promptly and effectively integrate ADVA’s businesses; management’s time and attention is diverted on transaction related issues; disruption from the transaction makes it more difficult to maintain business, contractual and operational relationships; the credit ratings of the combined company declines following the proposed Business Combination; legal proceedings are instituted against ADTRAN, ADVA or the combined company; ADTRAN, ADVA or the combined company is unable to retain key personnel; and the announcement or the consummation of the proposed Business Combination has a negative effect on the market price of the capital stock of ADTRAN and common shares of ADVA or on ADTRAN’s and ADVA’s operating results.

No assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, what impact they will have on the results of operations, financial condition or cash flows of ADTRAN or ADVA. Should any risks and uncertainties develop into actual events, these developments could have a material adverse effect on the proposed transaction and/or ADTRAN or ADVA, ADTRAN’s ability to successfully complete the proposed transaction and/or realize the expected benefits from the proposed transaction. You are cautioned not to rely on ADTRAN’s and ADVA’s forward-looking statements. These forward-looking statements are and will be based upon management’s then-current views and assumptions regarding future events and operating performance, and are applicable only as of the dates of such statements. Neither ADTRAN nor ADVA assumes any duty to update or revise forward-looking statements, whether as a result of new information, future events or otherwise, as of any future date.

7.3 As a result of the Merger and without any action on the part of any holder of any capital stock of Acorn, each Acorn Excluded Share shall cease to be outstanding, shall be cancelled and retired without payment of any consideration therefor and shall cease to exist.

24

7.5 In accordance with Section 262 of the DGCL, no appraisal rights shall be available to Acorn shareholders in connection with the Merger.

The number of Holdco Shares subject to each such Bidder Option shall be equal to the number of Acorn Shares subject to such Acorn Option immediately prior to the Effective Time and such Bidder Option shall have an exercise price per share equal to the per-share exercise price applicable to such Acorn Option immediately prior to the Effective Time.

7.7 At the Effective Time, each restricted stock unit measured in Acorn Shares (an “Acorn RSU”), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall, without any required action on the part of the holder thereof, cease to represent an Acorn RSU and shall be converted into a restricted stock unit measured in Holdco Shares (a “Bidder RSU”) on the same terms and conditions as were applicable to such Acorn RSU immediately prior to the Effective Time. The number of Holdco Shares subject to each such Bidder RSU shall be equal to the number of Acorn Shares subject to such Acorn RSU immediately prior to the Effective Time.

7.8 At the Effective Time, each performance share unit measured in Acorn Shares (an “Acorn PSU”), whether vested or unvested, which is outstanding immediately prior to the Effective Time shall, without any required action on the part of the holder thereof, cease to represent an Acorn PSU and shall be converted into a Bidder RSU on the same terms and conditions (other than the elimination of performance conditions) as were applicable to such Acorn PSU. The number of Holdco Shares subject to each such Bidder RSU (assuming target performance) shall be equal to the target number of Acorn Shares subject to such Acorn PSU. Any accrued but unpaid dividend equivalents with respect to any Acorn PSU will be assumed by the Bidder and become an obligation with respect to the applicable Bidder RSU.

25

7.9 At the Effective Time, each restricted stock award with respect to Acorn Shares (an “Acorn Restricted Stock Award”) that is outstanding immediately prior to the Effective Time shall, without any required action on the part of the holder thereof, be converted into a restricted stock award with respect to Holdco Shares (a “Bidder Restricted Stock Award”) with the same terms and conditions as were applicable under such Acorn Restricted Stock Award immediately prior to the Effective Time. The number of Holdco Shares subject to each such Bidder Restricted Stock Award shall be equal to the total number of Acorn Shares subject to such Acorn Restricted Stock Award immediately prior to the Effective Time. Any accrued but unpaid dividend equivalents with respect to any Acorn Restricted Stock Award will be assumed by the Bidder and become an obligation with respect to the applicable Bidder Restricted Stock Award.

7.10 At the Effective Time, the Bidder shall assume all the obligations of Acorn under the Acorn Equity Plans and the agreements evidencing the grants of Acorn Options, Acorn RSUs, Acorn PSUs and Acorn Restricted Stock Awards (collectively, “Acorn Equity Awards”), and the number and kind of shares available for issuance under each Acorn Equity Plan shall be adjusted to reflect Holdco Shares in accordance with the provisions of the applicable Acorn Equity Plan. As soon as practicable after the Effective Time, the Bidder shall deliver to the holders of Acorn Equity Awards appropriate notices setting forth such holders’ rights pursuant to the respective Acorn Equity Plans and agreements evidencing the grants of such Acorn Equity Awards and stating that such Acorn Equity Awards have been assumed by the Bidder and converted into Bidder Options, Bidder RSUs, Bidder PSUs and Bidder Restricted Stock Awards and shall continue in effect on substantially the same terms and conditions (but subject to the adjustments required by this Section 7 after giving effect to the Merger, the adjustment of Acorn PSUs required by Section 7.8 and the terms of the Acorn Equity Plans).

7.11 Prior to the Effective Time, Acorn shall take all actions necessary (including adopting such resolutions of the Acorn Board or any committee of the Acorn Board) to effectuate the treatment of Acorn Equity Awards contemplated by this Section 7. The Bidder shall take all corporate action necessary to reserve for issuance a sufficient number of Holdco Shares for delivery with respect to the treatment of converted Acorn Equity Awards in accordance with this Section 7. The Bidder shall file with the SEC, as soon as practicable following the Effective Time, a post-effective amendment to the Registration Statement or a registration statement on Form S-8 (or any successor form) with respect to the Holdco Shares subject to the Bidder Options, the Bidder RSUs and the Bidder Restricted Share Awards, as required.

26

8.1 Immediately prior to or substantially concurrently with the Effective Time, the Bidder shall issue and deliver to the Exchange Agent solely for the account and benefit of the former Acorn shareholders, Holdco Shares representing the maximum number of Holdco Shares that has become issuable pursuant to Section 7.1 for delivery of the Merger Consideration to the recipients entitled thereto (such Holdco Shares being the “Exchange Fund”). At the Effective Time, the obligations of the Bidder and the Exchange Agent under this Section 8.1 shall be unconditional.

8.2 As promptly as practicable after the Effective Time, the Bidder shall cause the Exchange Agent to mail to each holder of record of Acorn Eligible Shares that are (i) Acorn Certificates or (ii) Acorn Book-Entry Shares not held through the Depositary Trust Company (“DTC”) notice advising such holder of the effectiveness of the Merger, including (A) appropriate transmittal materials specifying that delivery shall be effected, and risk of loss and title to the Acorn Certificates or Acorn Book-Entry Shares shall pass only upon delivery of the Acorn Certificates (or affidavits of loss in lieu of the Acorn Certificates as provided in Section 8.8) or transfer of the Acorn Book-Entry Shares to the Exchange Agent (including customary provisions with respect to delivery of an “agent’s message” with respect to Acorn Book-Entry Shares), such materials to be in such form and have such other provisions as Acorn and the Bidder, desire (the “Letter of Transmittal”), and (B) instructions for surrendering the Acorn Certificates (or affidavits of loss in lieu of the Acorn Certificates) or transferring the Acorn Book-Entry Shares to the Exchange Agent in exchange for the Merger Consideration and any dividends or distributions, in each case, to which the holder has the right to receive pursuant to Section 8.4. With respect to Acorn Book-Entry Shares held through DTC, Acorn and the Bidder shall cooperate to establish procedures with the Exchange Agent and DTC to ensure that the Exchange Agent will transmit to DTC or its nominees as soon as reasonably practicable on or after the date of the Closing, upon surrender of Acorn Eligible Shares held of record by DTC or its nominees in accordance with DTC’s customary surrender procedures, the Merger Consideration and any dividends or distributions, in each case, to which the beneficial owners thereof are entitled pursuant to the terms of this Agreement.

27

8.3 The procedures for the surrender of Acorn Shares are as follows:

8.3.1 After the Effective Time, and (x) upon surrender to the Exchange Agent of Acorn Eligible Shares that are Acorn Certificates, by physical surrender of such Acorn Certificate (or affidavit of loss in lieu of an Acorn Certificate, as provided in Section 8.8) in accordance with the terms of the Letter of Transmittal and accompanying instructions, (y) upon the transfer of Acorn Eligible Shares that are Acorn Book-Entry Shares not held through DTC, in accordance with the terms of the Letter of Transmittal and accompanying instructions or (z) upon the transfer of Acorn Eligible Shares that are Acorn Book-Entry Shares held through DTC, including by delivery of an “agent’s message”, in accordance with DTC’s customary procedures and such other procedures as agreed by Acorn, the Bidder, the Exchange Agent and DTC, the holder of such Acorn Eligible Shares shall be entitled to receive in exchange therefor, and the Exchange Agent shall be required to deliver to each such holder (subject to Section 8.7), (A) the number of Holdco Shares (in book-entry form) in respect of the aggregate Merger Consideration that such holder is entitled to receive pursuant to Section 7 (after taking into account all Acorn Eligible Shares then held by such holder), and (B) any cash in respect of any dividends or other distributions which the holder has the right to receive pursuant to Section 8.4.

8.3.2 No interest will be paid or accrued on any amount payable upon due surrender of the Acorn Eligible Shares, and any Acorn Certificate formerly representing Acorn Eligible Shares that have been so surrendered shall be cancelled by the Exchange Agent. The Holdco Shares issued and paid in accordance with the terms of this Section 8 upon conversion of any Acorn Eligible Shares shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Acorn Eligible Shares.

28

8.3.3 In the event of a transfer of ownership of any Acorn Eligible Share that is not registered in the transfer records of Acorn, the proper number of Holdco Shares may be transferred by the Exchange Agent to such a transferee if (A) in the case of Acorn Book-Entry Shares, written instructions authorizing the transfer of the Acorn Book-Entry Shares are presented to the Exchange Agent, (B) in the case of Acorn Certificates, the Acorn Certificates formerly representing such Acorn Eligible Shares are surrendered to the Exchange Agent, and (C) the written instructions, in the case of clause (A), and Acorn Certificates, in the case of clause (B), are accompanied by all documents required to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid or are not applicable, in each case, in form and substance, reasonably satisfactory to the Bidder and the Exchange Agent. If any Holdco Shares are to be delivered to a Person other than the holder in whose name any Acorn Eligible Shares are registered, it shall be a condition of such exchange that the Person requesting such delivery shall pay any transfer or other similar taxes required by reason of the transfer of Holdco Shares to a Person other than the registered holder of any Acorn Eligible Shares, or shall establish to the satisfaction of the Bidder and the Exchange Agent that such tax has been paid or is not applicable. For the purposes of this Agreement, the term “Person” means any individual, corporation (including not-for-profit), general or limited partnership, limited liability company, joint venture, estate, trust, association, organization or governmental entity or other entity of any kind or nature.

8.4 All Holdco Shares to be transferred to the Exchange Agent pursuant to Section 8.1 shall be deemed issued and outstanding as of the Effective Time and whenever a dividend or other distribution is declared by the Bidder in respect of Holdco Shares, the record date for which is at or after the Effective Time, that declaration shall include dividends or other distributions in respect of all Holdco Shares issuable pursuant to this Agreement. No dividends or other distributions in respect of the Holdco Shares shall be paid to any holder of Acorn Eligible Shares until the Acorn Certificate is surrendered (or affidavit of loss in lieu of the Acorn Certificate is delivered as provided in Section 8.8) or the Acorn Book-Entry Share is transferred for exchange in accordance with this Section 8. Subject to the effect of applicable laws, following such surrender or transfer, there shall be issued to the holder of Holdco Shares issued in exchange for Acorn Eligible Shares in accordance with this Section 8, without interest, (A) at the time of such surrender or transfer, the dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such Holdco Shares and not paid and (B) at the appropriate payment date, the dividends or other distributions payable with respect to such Holdco Shares with a record date after the Effective Time but with a payment date subsequent to surrender.

8.5 From and after the Effective Time, there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of Acorn Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Acorn Book-Entry Shares or Acorn Certificates formerly representing Acorn Shares are presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be canceled and exchanged as provided in this Section 8.

29

8.6 Each of the Bidder, the Surviving Corporation and the Exchange Agent shall be entitled to deduct and withhold from any amounts payable pursuant to this Agreement to any Person who was a holder of Acorn Shares or Acorn Equity Awards immediately prior to the Effective Time, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or non-U.S. tax law. To the extent that amounts are so deducted and withheld by or on behalf of the Bidder, the Surviving Corporation or the Exchange Agent, as the case may be, and paid over to the relevant governmental entity, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Acorn Shares or Acorn Equity Awards, as the case may be, in respect of which such deduction and withholding was made.

8.7 Any portion of the Exchange Fund that remains unclaimed by the former Acorn shareholders for 180 days after the Effective Time shall be delivered to the Bidder. Any former Acorn shareholders who have not theretofore complied with this Section 8 shall thereafter look only to the Bidder for delivery of any Holdco Shares of such shareholders and payment of any dividends and other distributions in respect of Holdco Shares of such shareholders payable and/or issuable pursuant to Sections 7.1 and 8.4, in each case, without any interest thereon. Notwithstanding the foregoing, none of the Bidder, the Surviving Corporation, the Company, Merger Sub, the Exchange Agent or any other Person shall be liable to any former Acorn shareholder for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. Any Merger Consideration remaining unclaimed by former holders of Acorn Shares immediately prior to such time as such amounts would otherwise escheat to or become property of any governmental entity shall, to the fullest extent permitted by applicable law, become the property of the Bidder free and clear of any claims or interest of any Person previously entitled thereto.

8.8 In the event any Acorn Certificate representing Acorn Shares shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the Person claiming such Acorn Certificate to be lost, stolen or destroyed and, if required by the Bidder, the posting by such Person of a bond in customary amount and upon such terms as may be required by the Bidder or the Exchange Agent as indemnity against any claim that may be made against it with respect to such Acorn Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Acorn Certificate the Holdco Shares and any dividends or other distributions that would be payable or deliverable in respect thereof pursuant to this Agreement had such lost, stolen or destroyed Acorn Certificate been surrendered.

30

9 Support of the Exchange Offer by the Company, Shareholders’ Approval of the Merger and mutual actions to support the Transaction

9.1 The Parties shall use all reasonable efforts to facilitate the success of the Exchange Offer and the Merger.

9.2 Acorn shall use all reasonable efforts to call the Acorn Special Shareholder Meeting and obtain the Acorn Shareholders’ Approval prior to the end of the Acceptance Period, in particular

9.2.2 immediately after the Registration Statement becomes effective, Acorn shall (A) duly give notice of the Acorn Special Shareholders’ Meeting, (B) cause the Proxy Statement/Prospectus to be mailed to the Acorn shareholders and (C) duly convene and hold the Acorn Special Shareholders’ Meeting for a date no later than thirty-five days following the date the Registration Statement becomes effective, in each case, in accordance with its Governing Documents and applicable law, for the purposes of obtaining the Acorn Shareholders’ Approval;

9.2.3 as long as this Agreement has not been terminated or after the Publication of the Offer Document the Acceptance Period is still running, Acorn undertakes to the Company not to revoke or postpone the Acorn Special Shareholders’ Meeting once it has been called, provided that Acorn may adjourn or postpone the Acorn Special Shareholders’ Meeting (A) to solicit additional proxies for the purpose of obtaining the Shareholders’ Approval, (B) due to the absence of a quorum or (C) to allow reasonable additional time for (1) the filing and mailing of any supplemental or amended disclosure which Acorn has determined in good faith after consultation with outside legal counsel is necessary under applicable law and (2) for such supplemental or amended disclosure to be disseminated and reviewed by Acorn’s shareholders prior to the Acorn Special Shareholders’ Meeting;

31

9.2.4 unless a Modification in Recommendation has occurred, the Acorn Board shall recommend to its shareholders the (A) adoption of this Agreement and include such recommendation in the Proxy Statement/Prospectus and (B) adoption and approval of any other proposals as either the SEC or NASDAQ (or the respective staff members thereof) may indicate are necessary in its comments to the Proxy Statement/Prospectus.

9.3 From the time of signing this Agreement to the earlier of (i) the termination of this Agreement and (ii) the Closing, to the extent legally permissible and subject to the limitations set out in this Agreement, the Company shall endorse and support the Transaction and Exchange Offer in all related publications and communications.

9.4 The Company shall reasonably cooperate with Acorn to provide for a smooth and efficient implementation of the communications strategy, agreed among the Parties, with regard to retail investors, institutional investors, hedge funds and other shareholders to achieve the highest acceptance rate possible. Upon notification to the Company in writing or via email of the terms and conditions of requiring external assistance (if any), Acorn assumes such reasonable out-of-pocket costs and external advisor fees which directly relate to providing such assistance on the request or initiative of Acorn or the Bidder but excluding any overhead costs and overtime hours. For the avoidance of doubt, any costs, fees and expenses incurred by any member of the Alpine Group in connection with the Exchange Offer relating to matters which are independent of any such specific request or initiative of Acorn or the Bidder to facilitate the support of the Exchange Offer shall be borne solely by the relevant member of the Alpine Group.

9.5 To the extent legally possible and subject to the limitations contained in this Agreement, the Company hereby undertakes that from the day of signing this Agreement to the earlier of (i) the termination of the Agreement and (ii) the Closing it will refrain, and will procure that any other member of the Alpine Group will refrain, from initiating any measures or steps which may adversely affect the success or the timely completion of the Exchange Offer or the agreements of the Parties set forth herein.

9.6 The Company will (i) inform Acorn and the Bidder as soon as legally possible under statutory law and reasonably practical if it has been approached by a third party in relation to a situation, which could reasonably be expected to result in a public offer for Alpine Shares by a third party (a “Competing Offer”), or other transactions that, if implemented, would jeopardize the success of the Exchange Offer and (ii) disclose to Acorn the material terms and contents of such Competing Offer. The Company will not enter into any agreement which may reasonably interfere with such obligations.

32

9.7 Further, the Company shall not and shall ensure that no other member of the Alpine Group will, directly or indirectly:

9.7.1 solicit, i.e., actively ask for, a Competing Offer, or another transaction, proposal or approach which is economically or otherwise comparable to or competitive with a Competing Offer and that, if implemented, could impair, interfere with, hinder, delay or otherwise adversely affect the consummation of the Exchange Offer; or

9.7.2 enter into any communications, discussions, negotiations, correspondence or arrangements or make available any confidential documents relating to the Alpine Group or its business with a view to actively soliciting any Competing Offer or any other transaction that if implemented could impair, interfere with, hinder, delay or otherwise adversely affect the consummation of the Exchange Offer.

9.8 Nothing in this Agreement shall prevent the Company, the Management Board, the Supervisory Board or any other member of the Alpine Group from:

9.8.1 providing information duly requested or required by a regulatory authority;

9.8.2 reviewing any proposal by a third party;

9.8.3 engaging with a third party that submits a bona fide unsolicited proposal that (a) is reasonably likely to result in a fully financed Competing Offer that is a not only insignificantly (unbedeutend) superior transaction than the Transaction (taking into account the material expected benefits, including synergies, of the Transaction) (a “Superior Offer”) and (b) in relation to which no member of the Alpine Group breached Section 9.7.1 and provided that the Company has made available to the Bidder any non-public information it has made available to such third party to the extent such information was not previously provided to the Bidder;

33

9.8.4 including any statement in the Reasoned Statement which is required by law, case-law (Rechtsprechung) or the administrative practice of BaFin;

9.8.5 acting in accordance with (i) their fiduciary and other duties under applicable law, in particular, the duty of care and loyalty under Sections 93 and 116 German Stock Corporation Act (Aktiengesetz – “AktG”), (ii) the concept of managerial neutrality (Section 33 WpÜG) and (iii) managerial tasks and duties including the business judgment rule (Sections 76, 93 as well as 116 AktG). For the avoidance of doubt, a non-fulfilment of provisions under the agreement required by fiduciary and other duties under applicable law will not be (or result in) a breach of any of the Company’s obligations under this Agreement.

9.9 Nothing in this Agreement shall prevent Acorn or the Acorn Board from making an amendment, withdrawal, qualification or modification of its recommendation to its shareholders as described in Section 9.2.4 (such amendment, withdraw, qualification or modification a “Modification in Recommendation”) if the Acorn Board determines in good faith, after consultation with external legal counsel of recognized standing, that failure to effect a Modification in Recommendation would be inconsistent with the fiduciary duties of the directors of Acorn under applicable law. For the avoidance of doubt, a Modification in Recommendation will not be (or result in) a breach of any of Acorn’s obligations under this Agreement.

9.10 The Parties shall promptly notify each other of the occurrence of any circumstance which would be reasonably likely to result in a Closing Failure or the non-compliance with any of such Party’s obligations under this Agreement, or which would otherwise be reasonably likely to have a negative impact on the completion of the Transaction.

10 Reasoned Statement by the Company’s Corporate Bodies on the Exchange Offer

10.1 Without undue delay (unverzüglich), and in any case within two (2) weeks from the publication of the Offer Document, the Management Board and the Supervisory Board shall (i) prepare a statement required pursuant to Section 27 WpÜG (begründete Stellungnahme, the “Reasoned Statement”) either separately or jointly, (ii) publish the Reasoned Statement pursuant to Sections 27 para 3 and 14 para. 3 WpÜG and (iii) not withdraw or amend adversely to Acorn or withdraw their intention, or otherwise breach their obligation, to provide, the Reasoned Statement as long as the requirements set forth in Sections 10.2 are fulfilled.

34

10.2 In the Reasoned Statement of the Management Board and Supervisory Board it shall be reflected that the Management Board and Supervisory Board, after having duly reviewed and analyzed the Exchange Offer (including reviewing the Offer Document) and acting in good faith with regard to their duties, (i) regard the Exchange Ratio and the Offer Consideration as fair, adequate and attractive, (ii) welcome and support the Exchange Offer and (iii) recommend to the holders of Alpine Shares the acceptance of the Exchange Offer, provided that:

10.2.1 the Exchange Offer complies with the terms of this Agreement;

10.2.2 in case of a Superior Offer, if the Company has without undue delay (unverzüglich) notified the Bidder after becoming aware of the Superior Offer, the more beneficial terms can be matched and the Bidder has matched such more beneficial terms within ten (10) Business Days following the publication of the offer document relating to such Superior Offer (“the Bidder’s right to match”); and

10.2.3 no other circumstances exist that, as confirmed in writing to the Management Board by an external legal counsel of recognized standing, would cause the members of the Management Board to violate their duties under applicable law by welcoming and supporting the Exchange Offer or not issuing a recommendation for a Competing Offer.

For the avoidance of doubt, without limiting the generality of the foregoing, the members of the Management Board and Supervisory Board shall not be restrained in their right to issue a recommendation for a Superior Offer if and to the extend not issuing such recommendation would, as confirmed in writing by an external legal counsel of recognized standing, cause the members of the Management Board and Supervisory Board to breach their duties.

10.3 The Company will instruct a financial advisor to the Company to deliver an opinion to the Management Board and the Supervisory Board on the date of the Reasoned Statement with respect to the fairness to the holders of Alpine Shares, from a financial point of view, of the Offer Consideration to be received by holders of Alpine Shares in the Exchange Offer. This clause does not contain any representation by the Company regarding the result of the fairness opinion.

35

10.4 The Management Board and Supervisory Board will afford the Bidder and its advisors the opportunity to, and the Bidder and its advisors shall, review the Reasoned Statement prior to its publication.

12.4 The Bidder values the Company’s SAP and Salesforce applications and does not intend to change them.

12.5 Any dividend policy will duly consider the financial needs of the Company and its subsidiaries in light of its business strategy.

On 30 August 2021, Acorn HoldCo, Inc. (the “Bidder”), a newly formed corporation incorporated under the laws of Delaware, United States, and a wholly-owned subsidiary of ADTRAN, Inc., a company incorporated under the laws of Delaware, United States with registered address in Wilmington, United States (“ADTRAN”), decided to make a voluntary public takeover offer (freiwilliges öffentliches Übernahmeangebot) to the shareholders of ADVA Optical Networking SE (the “Company”) for the acquisition of all non-par value bearer shares in the Company (ISIN DE0005103006), each share representing a proportionate amount of EUR 1.00 of the share capital of the Company, (the “ADVA Shares”) in the form of an exchange offer (the “Exchange Offer”).

As consideration for the tendered ADVA Shares, the Bidder offers for each tendered ADVA Share 0.8244 common shares in the Bidder (the “HoldCo Shares”).

Annex 4.1.1 - 1

Shortly prior to the settlement of the Exchange Offer, ADTRAN shall become a wholly-owned subsidiary of the Bidder through a merger of ADTRAN as surviving entity and an indirect wholly-owned subsidiary of the Bidder (“MergerSub”) in accordance with applicable Delaware law (the “Merger”). The Merger will be subject to the launch of the Exchange Offer and satisfaction of all offer conditions (as described below) of the Exchange Offer. Upon completion of the Exchange Offer and the Merger (together, the “Business Combination”), the Bidder will become the holding company for the Company and ADTRAN.

The Exchange Offer will be subject to certain closing conditions, including the approval by a majority of ADTRAN shareholders, a minimum acceptance threshold of 70% of all ADVA Shares outstanding, antitrust approvals and foreign investment control clearances, the declaration of effectiveness by the U.S. Securities and Exchange Commission of the Registration Statement on Form S-4 regarding the issuance of HoldCo Shares, as well as other customary offer conditions.

The Bidder has concluded an irrevocable undertaking with EGORA Holding GmbH and its wholly-owned subsidiary EGORA Investments GmbH, under which such shareholders have committed to accept the Exchange Offer for in total 7,000,000 ADVA Shares which are held by them (representing approximately 13.7% of the Company’s share capital). The irrevocable undertaking qualifies as an “instrument” within the meaning of Section 38 German Securities Trading Act (Wertpapierhandelsgesetz, WpHG).

Today, ADTRAN, MergerSub, the Bidder and the Company entered into a business combination agreement regarding the principal terms and conditions of the Business Combination and the Exchange Offer as well as the mutual intentions and understandings with regard to the future collaboration.

Munich, Germany, 30 August 2021. Today, ADVA Optical Networking SE (“ADVA”) and ADTRAN, Inc. (“ADTRAN”) have signed a business combination agreement (“BCA”) to combine the two companies, creating a leading global product and service provider of end-to-end fiber networking solutions for communications service provider, enterprise and government customers. In order to achieve the business combination, ADVA and ADTRAN shall be combined under a new holding company (“HoldCo”) that was incorporated by ADTRAN as its subsidiary and will apply for an admission of its shares to be traded on NASDAQ and on the Frankfurt Stock Exchange. Pursuant to the BCA, ADTRAN and ADVA will each become a direct subsidiary of HoldCo; ADTRAN through a merger pursuant to US-law and ADVA by means of a public exchange offer (“Offer”) to all ADVA shareholders. HoldCo will publish its decision to make a voluntary public takeover offer in form of an exchange offer to all ADVA shareholders, pursuant to Section 10 para. 1 and 3 of the German Takeover Act (WpÜG).

Under the terms of the offer, each ADVA share will be exchanged for 0.8244 HoldCo shares, valuing ADVA at EUR 17.17 per share based on ADTRAN’s closing share price of USD 24.57 and representing a premium of 33% to ADVA’s closing price, each as of August 27, 2021, the last trading day prior to the signing of the BCA. On a three-months volume-weighted average basis, the offer is equivalent to EUR 14.98 per ADVA share based on ADTRAN’s three-months volume-weighted average share price as of August 27, 2021, representing a premium of 22% to ADVA’s three-months volume-weighted average share price for the same period, an equity value of EUR 789 million, and an enterprise value of EUR 759 million for an implied multiple of 1.3x LTM Revenue. ADTRAN shares will be exchanged for shares in the new holding company on a one-for-one basis. After the business combination, former ADVA shareholders would own approximately 46% of the combined company’s equity and former ADTRAN shareholders approximately 54%, if all ADVA shareholders were to fully subscribe to the Offer.

Closing of the transaction is expected to occur during the second or third quarter of 2022 and will be subject to certain conditions. These will include receipt of all required merger control and foreign investment control clearances, a minimum acceptance rate of 70% of the outstanding shares in ADVA, the approval by ADTRAN shareholders, the non-performance of certain actions by ADVA, as well as the non-occurrence of certain material adverse events and other customary closing conditions.

Annex 4.1.2 - 1

The members of ADVA’s management and supervisory boards welcome the Offer. Subject to a thorough analysis of the Offer document, their fiduciary and other legal obligations, they intend to support the Offer.

The HoldCo has concluded an irrevocable undertaking with EGORA Holding GmbH and its wholly-owned subsidiary EGORA Investments GmbH, under which such shareholders have committed to accept the Exchange Offer for shares which represent approximately 13.7% of ADVA’s share capital.

The combined company will be named ADTRAN Holdings, Inc., and have its global headquarters in Huntsville, Alabama. The European headquarters will be in Planegg/Martinsried near Munich. HoldCo’s board of directors will, after closing, consist of nine members and be staffed by three representatives of ADVA and six representatives of ADTRAN.

Based on the published results for the twelve months ended June 30, 2021, the combined company generates about USD 1.2bn in yearly turnover. With the business combination, ADVA and ADTRAN aim to achieve annual run rate pre-tax synergies of approximately USD 52m (EUR 44m) by year 2 post-closing. In order to achieve these synergies, one-off-expenses of approximately USD 37m (EUR 31m) are to be estimated, whereby the parties’ transaction costs are already included.

Both companies are pioneers in open, disaggregated solutions with a shared vision for the future of fiber networking. The combined business will offer a comprehensive portfolio for providing homes, businesses and 5G infrastructure with scalable, secure and assured fiber connectivity, paired with cloud-managed Wi-Fi connectivity and SaaS applications that optimize the performance of the network and improve the customer experience.

TRANSACTION DETAILS

ADTRAN and ADVA will combine under a new holding company (which will be renamed ADTRAN Holdings, Inc. following the closing) pursuant to an all-stock exchange offer for 100% of ADVA’s outstanding shares.

Under the terms of the offer, each ADVA share will be exchanged for 0.8244 shares of common stock in the new holding company. The offer is equivalent to €14.98 per ADVA share based on ADTRAN’s 3-month VWAP as of August 27, 2021, representing a premium of 22% to ADVA’s 3-month VWAP for the same time period, an equity value of €789 million, and an enterprise value of €759 million for an implied multiple of 1.3x LTM Revenue.

At the closing, ADTRAN shareholders will own approximately 54% of the equity of the combined company and ADVA shareholders will own approximately 46%, assuming a tender of 100% of ADVA shares.

The offer will be subject to certain closing conditions, including a minimum acceptance threshold of 70% of the outstanding shares in ADVA, majority approval by ADTRAN shareholders, regulatory approvals, and other customary closing conditions.

The business combination agreement has been approved unanimously by the ADTRAN Board of Directors and the ADVA Management and Supervisory Boards. The transaction also has the strong support of ADVA’s largest shareholder, Egora, which has entered into an irrevocable commitment to tender into the offer shares representing 13.7% of ADVA’s outstanding shares.

The companies anticipate completing the transaction during the second or third quarter of 2022, subject to receipt of required regulatory approvals, as well as satisfaction of other customary closing conditions. The new holding company, in coordination with the ADVA Management and Supervisory Boards, intends to pursue a delisting and squeeze-out of the ADVA shares, following settlement of the offer or at a later date, depending on the new holding company’s shareholding in ADVA, prevailing market conditions and other economic considerations.

ADVA CEO Letter to All ADVA Employees

Subject Line: Important Update

All,

I am very excited to announce our market impacting strategic news that will strengthen our competitive position, as well as secure our hard work over the last few years.

As you may have seen, we are combining with ADTRAN, creating a global innovation powerhouse in converged access and packet edge fiber networking. Based in Huntsville, Alabama in the U.S., ADTRAN is a leading global provider of fiber access, fiber extension and subscriber connectivity solutions. This is the right path forward for our long-term success!

The combination with ADTRAN is consistent with our strategy to increase our scale by winning new customers and expanding our product offering for existing customers. Together, we will be able to offer customers differentiated, end-to-end fiber networking solutions spanning metro, edge, access, enterprise and subscriber connectivity. Combining with ADTRAN will help us to accelerate our growth by utilizing our larger scale, which will enhance our ability to compete and will enable cross-selling opportunities for our complementary product lines.

In addition to being a strong business fit, we share many of the same values and have a similar company culture. I first reached out to Tom, CEO of ADTRAN, almost 14 years ago, and we have established a strong relationship with mutual respect and a common vision for market developments. What I love is that Tom values people as much as we do. He values the customer experience as much as we do and he is transparent, clear, and as strong in his conviction as our own executive team. In addition, as a management team, we have gotten to know the entire ADTRAN leadership team throughout this process, and we are excited to join forces as we bring our two impressive companies together.

The transaction is expected to close during the second or third quarter of 2022, subject to regulatory approvals and other customary closing conditions. The mutual company will be listed on the NASDAQ and the Frankfurter exchange (Börse). Until we receive regulatory approval and close the transaction, ADVA and ADTRAN will continue to operate as separate companies.

In the meantime, our focus should remain on our core mission – innovation and customer experience. So, don’t get distracted as we need to put our heads down and focus on Q3 and beyond. In other words, it is business as usual. We are committed to being transparent with all of you throughout this process and will provide updated information as we reach key milestones. We will be hosting town hall meetings today and tomorrow, where we will share more details on this exciting announcement.

As with any announcement of this size, it will take us time to work through the details. For now, it will be business as usual. If you receive any inquiries from the press, please do not engage and forward immediately to Stephan Rettenberger at SRettenberger@adva.com.

This communication 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. You can generally identify forward-looking statements by the use of forward-looking terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “explore,” “evaluate,” “intend,” “may,” “might,” “plan,” “potential,” “predict,” “project,” “seek,” “should,” or “will,” or the negative thereof or other variations thereon or comparable terminology. These forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond ADTRAN’s and ADVA’s control.

These forward-looking statements include, but are not limited to, statements regarding benefits of the proposed business combination, integration plans and expected synergies, and anticipated future growth, financial and operating performance and results. Forward-looking statements involve risks and uncertainties that may cause actual results to be materially different from the results predicted or expected. No assurance can be given that these forward-looking statements will prove accurate and correct, or that projected or anticipated future results will be achieved. Factors that could cause actual results to differ materially from those indicated in any forward-looking statement include, but are not limited to: the expected timing and likelihood of the completion of the contemplated business combination, including the timing, receipt and terms and conditions of any required governmental and regulatory approvals of the contemplated business combination that could reduce anticipated benefits or cause the parties to abandon the transaction; the occurrence of any event, change or other circumstances that could give rise to the termination of the business combination agreement; the ability to successfully complete the proposed business combination; regulatory or other limitations imposed as a result of the proposed business combination; the success of the business following the proposed business combination; the ability to successfully integrate the ADTRAN and ADVA businesses; the possibility that ADTRAN stockholders may not approve the business combination agreement or that the requisite number of ADVA shares may not be tendered in the public offer; the risk that the parties may not be able to satisfy the conditions to closing of the proposed business combination in a timely manner or at all; risks related to disruption of management time from ongoing business operations due to the proposed business combination; the risk that the announcement or consummation of the proposed business combination could have adverse effects on the market price of ADTRAN’s common stock or ADVA’s common shares or the ability of ADTRAN and ADVA to retain customers, retain or hire key personnel, maintain relationships with their respective suppliers and customers, and on their operating results and businesses generally; the risk that Acorn HoldCo may be unable to achieve expected synergies or that it may take longer or be more costly than expected to achieve those synergies; the risk of fluctuations in revenue due to lengthy sales and approval process required by major and other service providers for new products; the risk posed by potential breaches of information systems and cyber-attacks; the risks that ADTRAN, ADVA or the post-combination company may not be able to effectively compete, including through product improvements and development; and such other factors as are set forth in ADVA’s annual and interim financial reports made publicly available and ADTRAN’s and Acorn HoldCo’s public filings made with the SEC from time to time, including but not limited to those described under the headings “Risk Factors” and “Forward-Looking Statements” in ADTRAN’s Form 10-K for the fiscal year ended December 31, 2020 and ADTRAN’s Form 10-Q for the quarterly period ended June 30, 2021, which are available via the SEC’s website at www.sec.gov.

ADVA Customer / Partner / Supplier Letter

Subject: Important Update

Dear [NAME],

I am writing to inform you of an exciting development at our company.

We announced that ADVA has entered into a business combination agreement with ADTRAN, a U.S.-based global leader in fiber access, fiber extension and subscriber connectivity solutions, to combine our two companies.

We believe our combination will create many opportunities to better serve end-to-end fiber networking solutions spanning metro edge, aggregation, access and subscriber connectivity. Additionally, we anticipate that by utilizing our collective world-class R&D and engineering teams, we will be better positioned to accelerate innovation and offer our customers differentiated solutions.

Going forward, it will be business as usual and all existing customer, partner and supplier relationships will remain intact. Until we receive all required regulatory approvals and close the transaction, ADVA and ADTRAN will continue to operate as separate companies. As we integrate the two companies, we will be focused on the best ways to offer our enhanced value proposition and partner with you.

If you have any questions, please do not hesitate to contact your ADVA representative with any questions or concerns. Once again, we greatly appreciate your partnership as we begin our next chapter. We look forward to speaking with you soon.

Yours sincerely,

Brian Protiva

CEO of ADVA

A squeeze-out transaction may be effected in three ways: (i) a cash merger squeeze-out pursuant to Sections 62(1) and 62(5) of the German Transformation Act, if the Bidder holds at least 90% of the Target’s share capital, excluding treasury shares and shares held for the account of the Target itself, (ii) a corporate squeeze-out pursuant to Sections 327a et seq. of the German Stock Corporation Act (Aktiengesetz), if the Bidder holds at least 95% of the Target’s share capital, excluding treasury shares and shares held for the account of the Target or (3) a takeover squeeze-out pursuant to Sections 39a et seq. of the German Takeover Act, if the Bidder acquires in connection with the Offer at least 95% of the Target’s share capital, excluding treasury shares and shares held for the account of the Target.

Annex 5.2.7 - 5

In the event of a cash merger squeeze-out or a corporate squeeze-out, shares of the Target Shareholders who did not tender their shares in the Offer will automatically be converted into the right to receive adequate cash compensation. In a squeeze-out transaction, the Bidder will determine the adequate compensation using the Target’s discounted earnings (Ertragswert) or, if appropriate, discounted cash flow, to value the the Target Shares. In general, the compensation must not be less than the VWAP of the Target Shares for the three-month period prior to the announcement of the Bidder’s intention to effect such squeeze-out transaction. In a takeover squeeze-out, the consideration offered in connection with the Offer shall be considered adequate where the Bidder has acquired, in connection with the Offer, shares representing not less than 90% of the share capital (excluding treasury shares) for which the Offer was made. Following the approval of a cash merger squeeze-out or a corporate squeeze-out by a shareholder meeting of the Target and its registration with the competent commercial register, each remaining minority Target Shareholder may challenge such determination pursuant to the German Appraisal Proceedings Act (Spruchverfahrensgesetz). The amount of compensation paid for Target Shares in an appraisal proceeding, if any, may be higher or lower than, or equal to, the Offer Consideration. However, appraisal rights are not available in connection with a takeover squeeze-out. If the Bidder is unable to complete a squeeze-out, the remaining Target Shareholders will continue to be entitled to all ordinary shareholder rights (except for annual dividends in the case of a DPLTA as defined below).

(ii) Domination and Profit and Loss Transfer Agreement

The Bidder may consider entering into a domination and profit and loss transfer agreement (“DPLTA”) with the Target if it is expected that the required 75% majority of the Target Shareholders in a shareholders’ meeting approving the DPLTA will be reached. The decision will depend on whether a DPLTA is needed to implement synergies and on the financial feasibility. Under a DPLTA, the Bidder would be able to give legally binding instructions to the executive board of the Target and would receive the full annual profit of the Target. Any loss would have to be balanced by the Bidder. A DPLTA would facilitate the integration of the Bidder and the Target Group and the implementation of synergies. However, the Target’s remaining shareholders would have to be granted a put right at the fair value of the Target Shares and would be entitled to a receive annual guaranteed dividend payment as compensation for the transfer of profits to the Bidder. The put price and the amount of the guaranteed dividend would be fixed in the DPLTA. The guaranteed dividend will be based on the amount that is likely to be distributed as the average dividend per share, given the Target’s past and current results of operations determined pursuant to the German Commercial Code (Handelsgesetzbuch) and the German Stock Corporation Act (Aktiengesetz), and the Target’s future earnings prospects. The put price shall reflect the intrinsic value of the Target Shares. It can be based on the market price, or determined on the basis of discounted earnings (Ertragswert) or discounted cash flow valuation method, but must not be less than the volume weighted average market price, or VWAP, of the Target shares for the three-month period prior to the announcement of the Bidder’s intention to enter into a DPLTA. The remaining Target minority shareholders can challenge the determination of the put price and guaranteed dividend in the DPLTA in appraisal proceedings pursuant to the German Appraisal Proceedings Act (Spruchverfahrensgesetz). The put price for ADVA shares in an appraisal proceeding, if any, may be higher or lower than, or equal to, the Offer Consideration.

Annex 5.2.7 - 6

(iii) Delisting

The Bidder may consider, depending on the stake of the Bidder, prevailing market conditions and other economic considerations, to implement, in coordination with and the support of the management board and the Supervisory Board, a withdrawal of the admission for trading of the Target Shares from all regulated markets (Regulierten Märkten) in accordance with the WpÜG and the German Stock Exchange Act (Börsengesetz – “BörsG”) (delisting) or as a result of a squeeze-out, and to apply or propose to suspend inclusion in the open market segments (Freiverkehr) of the stock exchanges Berlin, Düsseldorf, Hamburg, Hanover, Munich and Stuttgart as well as Tradegate Exchange.

Annex 6.7 - 3

Any repeal or modification of Section 7.1 of this Article VII by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.

ARTICLE VIII

Section 8.1    Indemnification. Each person who was or is made a party or is threatened to be made a party to or is involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she, or a person of whom he or she is the legal representative, is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director or officer of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director or officer or in any other capacity while serving as a director or officer shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts to be paid in settlement) reasonably incurred or suffered by such person in connection therewith, and such indemnification shall continue as to a person who has ceased to be a director or officer and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that except as provided in this Section 8.1 with respect to proceedings seeking to enforce rights to indemnification, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation. Further, the Corporation also may indemnify and hold harmless employees and agents of the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent such amendment permits the Corporation to provide broader indemnification rights than said law permitted the Corporation to provide prior to such amendment), and such discretionary authority to indemnify employees and agents of the Corporation shall be vested in, and may be exercised by, the Board of Directors of the Corporation; provided, however, that the Board of Directors of the Corporation shall have no discretionary authority relative to the indemnification of an employee or agent of the Corporation where the DGCL specifically provides that indemnification is mandatory. The right to indemnification conferred in this Article relative to directors and officers of the Corporation shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that, if the DGCL requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Article VIII or otherwise.

Section 8.2    Payment of Mandatorily Indemnified Claims. If a claim relative to which a director, officer, employee or agent is entitled to be mandatorily indemnified under Section 8.1 is not paid in full by the Corporation within ninety days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant also shall be entitled to be paid the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, independent legal counsel or stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or stockholders) that the claimant has not met such applicable standard of conduct shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Annex 6.7 - 4

Section 8.3    Non-Exclusivity. The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Article VIII shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

Section 8.4    Insurance. The Corporation may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Corporation would have the power to indemnify such person against such expense, liability or loss under the DGCL.

ARTICLE IX

Section 9.1    Severability. If any provision or provisions of this Certificate of Incorporation shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Certificate of Incorporation (including, without limitation, each portion of any paragraph of this Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not, to the fullest extent permitted by applicable law, in any way be affected or impaired thereby and (ii) to the fullest extent permitted by applicable law, the provisions of this Certificate of Incorporation (including, without limitation, each such portion of any paragraph of this Certificate of Incorporation containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.

ARTICLE X

Section 10.1    Forum: Court of Chancery. Unless the Corporation selects or consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (or, if and only if the Court of Chancery does not have subject matter jurisdiction, another state court sitting in the State of Delaware or, if and only if neither the Court of Chancery nor any state court sitting in the State of Delaware has subject matter jurisdiction, then the federal district court for the District of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (1) any derivative action or proceeding brought on behalf of the Corporation, (2) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, or other employee or stockholder of the Corporation to the Corporation or the Corporation’s stockholders, creditors or other constituents, or a claim of aiding and abetting any such breach of fiduciary duty, (3) any action asserting a claim against the Corporation or any director or officer of the Corporation arising pursuant to any provision of the DGCL or this Certificate of Incorporation or the Bylaws (as either may be amended and/or restated from time to time) or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, (4) any action to interpret, apply, enforce or determine the validity of this Certificate of Incorporation or the Bylaws, (5) any action asserting a claim against the Corporation or any director or officer of the Corporation governed by the internal affairs doctrine or (6) any other action asserting an “internal corporate claim” as that term is defined in Section 115 of the DGCL.

Section 10.2    Forum: Federal District Courts. Unless the Corporation selects or consents in writing to the selection of an alternative forum, the federal district courts of the United States shall be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under federal securities laws against the Corporation or any director or officer of the Corporation.

Annex 6.7 - 5

Section 10.3    Consent to Forum. To the fullest extent permitted by law, any person or entity purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article X and personal jurisdiction and venue in any state or federal court located in the State of Delaware for any action or proceeding set forth in above clauses 1 to 6 of Section 10.1 and any complaint set forth in Section 10.2.

ARTICLE XI

Section 11.1    Amendments. The Corporation reserves the right to amend, alter, change or repeal any provision contained in this Certificate of Incorporation, and other provisions authorized by the laws of the State of Delaware at the time in force may be added or inserted, in the manner now or hereafter prescribed by the laws of the State of Delaware, and all rights, preferences and privileges of whatsoever nature conferred upon stockholders, directors or any other person whomsoever by and pursuant to this Certificate of Incorporation in its present form or as hereafter amended are granted subject to this reservation.

Without limiting the manner by which notices of meetings otherwise may be given effectively to stockholders, any such notice may be given by electronic transmission in the manner provided in Section 232 of the Delaware General Corporation Law.

Notice of any meeting need not be given to any stockholder who shall, either before or after the meeting, submit a waiver of notice or who shall attend such meeting, except when the stockholder attends for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Any stockholder so waiving notice of the meeting shall be bound by the proceedings of the meeting in all respects as if due notice thereof had been given.

An affidavit of the Secretary, an Assistant Secretary or the transfer agent or other agent of the Corporation that notice has been duly given shall be evidence of the facts stated therein.

Section 2.5 Adjourned Meetings and Notice Thereof. Any meeting of stockholders may be adjourned to another time or place, and the Corporation may transact at any adjourned meeting any business which might have been transacted at the original meeting. Notice need not be given of the adjourned meeting if the time, place, if any, thereof, and the means of remote communication, if any, are announced at the meeting at which the adjournment is taken, unless (a) any adjournment or series of adjournments cause the original meeting to be adjourned for more than thirty days after the date originally fixed therefor, or (b) a new record date is fixed for stockholders entitled to vote at the adjourned meeting. If notice of an adjourned meeting is given, such notice shall be given to each stockholder of record entitled to vote at the adjourned meeting in the manner prescribed in Section 2.4 for the giving of notice of meetings.

If, however, such quorum shall not be present in person or represented at any meeting of stockholders, the chair of the meeting or the stockholders entitled to vote thereat, present in person or represented by proxy, shall have the power, by the affirmative vote of a majority in voting power thereof, to adjourn the meeting from time to time, in the manner provided in Section 2.5, until a quorum shall be present or represented. At any such adjourned meeting at which there is a quorum present, any business may be transacted that might have been transacted at the meeting originally called. When a quorum is once present to organize a meeting, the quorum cannot be destroyed by the subsequent withdrawal or revocation of the proxy of any stockholder. Shares of capital stock owned by the Corporation or by another corporation, if a majority of the shares of such other corporation entitled to vote in the election of Directors is held by the Corporation, shall not be counted for quorum purposes or entitled to vote.

Section 2.7 Voting.

(a)    General. At any meeting of stockholders, each stockholder holding, as of the record date, shares of capital stock entitled to be voted on any matter at such meeting shall have one vote on each such matter submitted to vote at such meeting for each such share of capital stock held by such stockholder, as of the record date, as shown by the list of stockholders entitled to vote at the meeting, unless the Certificate of Incorporation provides for more or less than one vote for any share, on any matter, in which case every reference in these Bylaws to a majority or other proportion of stock shall refer to such majority or other proportion of the votes of such stock.

(b)    Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent or dissent to corporate action in writing without a meeting may authorize another person or persons to act for him or her by proxy, provided that no proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. Such authorization may be in a writing executed by the stockholder or his or her authorized officer, director, employee, or agent. To the extent permitted by law, a stockholder may authorize another person or persons to act for him or her as proxy by transmitting or authorizing the transmission of an electronic transmission to the person who will be the holder of the proxy or to a proxy solicitation firm, proxy support service organization, or like agent duly authorized by the person who will be the holder of the proxy to receive such transmission, provided that the electronic transmission either sets forth or is submitted with information from which it can be determined that the electronic transmission was authorized by the stockholder. A copy, facsimile transmission, or other reliable reproduction of the proxy authorized by this Section 2.7(b) may be substituted for or used in lieu of the original writing or electronic transmission for any and all purposes for which the original writing or electronic transmission could be used, provided that such copy, facsimile transmission, or other reproduction shall be a complete reproduction of the entire original writing or electronic transmission. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only so long as, it is coupled with an interest, whether in the stock itself or in the Corporation generally, sufficient in law to support an irrevocable power. A stockholder may revoke any proxy that is not irrevocable by attending the meeting and voting in person or by delivering to the Secretary a revocation of the proxy or a new proxy bearing a later date.

(c)    Inspector. The Board of Directors, the Chairman of the Board, the Vice Chairman, the Chief Executive Officer, the President, or the person presiding at a meeting of stockholders may appoint one or more persons to act as inspectors of voting at any meeting with respect to any matter to be submitted to a vote of stockholders at such meeting, with such powers and duties, not inconsistent with applicable law, as may be appropriate. Unless otherwise required by applicable law, inspectors may be officers, employees or agents of the Corporation. Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath to execute faithfully the duties of inspector with strict impartiality and according to the best of such inspector’s ability.

Section 2.8 Action by Consent of Stockholders.

(a)    Unless otherwise provided in the Certificate of Incorporation, whenever any action by the stockholders at a meeting thereof is required or permitted by law, the Certificate of Incorporation or these Bylaws, such action may be taken without a meeting, without prior notice and without a vote, if a consent or consents in writing, setting forth the action so taken and bearing the dates of signature of the stockholders who signed the consent, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and is delivered to the Corporation by delivery to its registered office in the State of Delaware, the Corporation’s principal place of business, or any officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded.

Prompt notice of the taking of such action without a meeting and by less than unanimous written consent shall be given to those stockholders who have not consented in writing.

(b)    No written consent shall be effective to take the corporate action referred to therein unless, within 60 days of the earliest dated written consent received in accordance with this Section 2.8, a written consent or consents signed by a sufficient number of holders to take such action are delivered to the Corporation in the manner prescribed by this Section 2.8.

(c)    Any stockholder of record seeking to have the stockholders authorize or take action by written consent shall, by written notice to the Secretary of the Corporation, request the Board of Directors to fix a record date, as provided for in Section 5.8(b).

In no event shall the adjournment or postponement of an annual meeting commence a new time period (or extend any time period) for the giving of a Record Stockholder’s notice as described above. A Record Stockholder’s notice to the Secretary shall set forth or include, as the case may be, as to each matter the Record Stockholder proposes to bring before the meeting:

(i) a brief description of the business desired to be brought before the meeting, including the complete text of any resolutions to be presented at the meeting with respect to such business (and in the event that such business includes a proposal to amend these Bylaws, the language of the proposed amendment), and the reasons for conducting such business at the meeting;

(ii) the name and address of record of the Record Stockholder and any Stockholder Associated Person;

(viii) a representation that the Record Stockholder is a holder of record of shares of the Corporation entitled to vote at such meeting and intends to appear in person or by proxy at the meeting to propose such business; and

A Record Stockholder providing notice of business proposed to be brought before an annual meeting shall further update and supplement such notice, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.9(a) shall be true and correct as of the record date for the meeting, and such update and supplement shall be delivered to and received by the Secretary at the principal executive offices of the Corporation not later than ten (10) days after the record date for determining the stockholders entitled to vote at the meeting; provided, that if such date is after the date of the meeting, not later than the day prior to the meeting.

(b)    Notwithstanding anything in these Bylaws to the contrary, no business (except for the election of Directors in accordance with the procedures set forth in Section 3.4 of these Bylaws) shall be conducted at an annual meeting except in accordance with the procedures set forth in this Section 2.9. The chairperson of an annual meeting shall have the power to determine and declare to the meeting whether or not business was properly brought before the meeting in accordance with these provisions, and if he or she should determine that business was not properly brought before the meeting, to declare that such business shall not be transacted. Notwithstanding the foregoing provisions of this Section 2.9, unless otherwise required by law or determined by the Board of Directors in its sole discretion, if the Record Stockholder (or a qualified representative of the stockholder) does not appear at the annual meeting of stockholders of the Corporation to present proposed business, such proposed business shall not be transacted, notwithstanding that proxies in respect of such vote may have been received by the Corporation. For purposes of this Section 2.9, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

In addition to the requirements of this Section 2.9 with respect to any business proposed to be brought before an annual meeting, a stockholder shall comply with all applicable requirements of the Exchange Act with respect to any such business. Nothing in this Section 2.9 shall be deemed to affect the rights of stockholders to request inclusion in the Corporation’s proxy statement of proposals pursuant to Rule 14a-8 under the Exchange Act.

(d)    For purposes of these Bylaws, the term “Stockholder Associated Person” shall include each of the following persons: (i) any beneficial owner or beneficial owners, if different than the Record Stockholder, on whose behalf the notice of business in this Section 2.9 is made, (ii) any person controlling, directly or indirectly, or acting in concert with the Record Stockholder or such beneficial owner, (iii) any associate (within the meaning of Rule 12b-2 under the Exchange Act for purposes of these Bylaws) of such Record Stockholder, beneficial owner or person and (iv) any other participant in such solicitation (as described in paragraphs (a)(ii)-(vi) of Instruction 3 to Item 4 of Schedule 14A under the Exchange Act).

Section 3.1 General Powers. The property, business and affairs of the Corporation shall be managed by or under the direction of a Board of Directors. The Board of Directors may exercise all such powers of the Corporation and have such authority and do all such lawful acts and things as are permitted by law, the Certificate of Incorporation or these Bylaws.

Section 3.2 Number of Directors. The Board of Directors of the Corporation shall consist of one or more members. The exact number of Directors which shall constitute the whole Board of Directors shall be fixed from time to time by resolution adopted by a majority of the whole Board of Directors.

Section 3.3 Election. Except as otherwise provided by law, the Certificate of Incorporation or these Bylaws, after the first meeting of the Corporation at which Directors are elected, Directors of the Corporation shall be elected each year at the annual meeting of stockholders, or at a special meeting in lieu of the annual meeting called for such purpose, by a majority of votes cast at any meeting for the election of Directors at which a quorum is present; provided, however, that, Directors shall be elected by a plurality of the votes cast at any meeting of stockholders for which (i) the Secretary of the Corporation received a notice that a stockholder has nominated a person for election to the Board of Directors in compliance with the advance notice requirements for stockholder nominees for Director set forth in Section 3.4(a) of these Bylaws and (ii) such nomination has not been withdrawn by such stockholder on or prior to the tenth (10th) day preceding the date the Corporation first mails its notice of meeting for such meeting to the stockholders. For purposes of this Section 3.3, a majority of votes cast shall mean that the number of shares of shares voted “for” a nominee’s election exceeded the number of shares voted “against” such nominee’s election. The voting on Directors at any such meeting shall be by written ballot unless otherwise provided in the Certificate of Incorporation.

Section 3.4 Nominations for Election to the Board of Directors.

(a)    Only persons who are nominated in accordance with the following procedures shall be eligible for election as Directors. Nominations of persons for election to the Board of Directors may be made at any meeting of stockholders called for the election of Directors by (i) the Board of Directors or any committee designated by the Board of Directors or (ii) any stockholder of the Corporation entitled to vote for the election of Directors at such meeting (a “Nominating Record Stockholder”) if the nomination by such stockholder is made in accordance with the procedures established by this Section 3.4.

A Nominating Record Stockholder’s notice to the Secretary shall set forth or include, as the case may be:

For purposes of this Section 3.4, to be considered a qualified representative of the stockholder, a person must be a duly authorized officer, manager or partner of such stockholder or must be authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at the meeting of stockholders.

The Board of Directors may also require any proposed candidate for nomination as a Director to furnish such other information as may reasonably be requested by the Board of Directors in writing prior to the meeting of stockholders at which such candidate’s nomination is to be acted upon in order for the Board of Directors to determine the eligibility of such candidate for nomination and to determine the independence of such candidate to be an independent Director of the Corporation in accordance with the Exchange Act, applicable national securities exchange rules and the Corporation’s Corporate Governance Principles.

Section 3.8 Vacancies. Vacancies in the Board of Directors and newly created Directorships resulting from any increase in the authorized number of Directors shall be filled by a majority of the Directors then in office, though less than a quorum, or by a sole remaining Director. If one or more Directors shall resign from the Board of Directors effective at a future date, a majority of the Directors then in office, including those who have so resigned at a future date, shall have the power to fill such vacancy or vacancies, the vote thereon to take effect and the vacancy to be filled when such resignation or resignations shall become effective, and each Director so chosen shall hold office as provided in this Section 3.8.

A Director interested in a contract or transaction may be counted in determining the presence of a quorum at a meeting of the Board of Directors which authorizes the contract or transaction. In the absence of a quorum, a majority of the Directors present may adjourn the meeting until a quorum shall be present.

Annex 6.7 - 19

Unless the Certificate of Incorporation provides otherwise, members of the Board of Directors or any committee designated by the Board of Directors may participate in a meeting of the Board of Directors or such committee by means of a conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and participation in such a meeting shall constitute presence in person at such meeting.

The affirmative vote of the majority of the Directors present at a meeting at which a quorum is present shall be the act of the Board of Directors unless the Certificate of Incorporation or these Bylaws shall require a vote of a greater number.

Section 3.10 Regulations.

The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such a request is received, adopt a resolution fixing the record date (unless a record date has previously been fixed by the Board of Directors pursuant to the first sentence of this Section 5.8(b)). If no record date has been fixed by the Board of Directors within ten (10) days of the date on which such a request is received, the record date for determining stockholders entitled to consent to action in writing without a meeting, when no prior action by the Board of Directors is required by applicable law, shall be the first date on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or any officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Delivery made to the Corporation’s registered office shall be by hand or by certified or registered mail, return receipt requested. If no record date has been fixed by the Board of Directors and prior action by the Board of Directors is required by applicable law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the date on which the Board of Directors adopts the resolution taking such prior action.

ADTRAN and ADVA Announce Combination to Create Global, Scaled End-to-End Fiber Networking Solutions Leader

• Combination expands product offering and strengthens position as a global fiber networking innovation leader with combined revenue of $1.2B

• Highly complementary businesses create a global, scaled end-to-end provider to better serve customers with differentiated fiber networking solutions, spanning metro edge, aggregation, access and subscriber connectivity

• Creates a stronger and more-profitable company, poised to benefit from the unprecedented investment cycle in fiber, an expanded market opportunity and increased scale

• Meaningful value creation with over $50 million in annual run-rate cost synergies

• All-stock transaction with ADTRAN shareholders to own approximately 54% and ADVA shareholders to own approximately 46% of the combined company, assuming a tender of 100% of ADVA shares

• Combined company to be dual-listed on the NASDAQ and Frankfurt Stock Exchange

HUNTSVILLE, AL and MUNICH, GERMANY, AUGUST 30, 2021 –ADTRAN, Inc. [Nasdaq: ADTN] and ADVA [FSE: ADV] announced today the entry into a business combination agreement to combine the two companies and create a leading global, scaled provider of end-to-end fiber networking solutions for communications service provider, enterprise and government customers. The merger combines ADTRAN’s global leadership in fiber access, fiber extension and subscriber connectivity solutions with ADVA’s global leadership in metro wavelength division multiplexing, data center interconnect, business ethernet and network synchronization solutions.

Both companies are pioneers in open, disaggregated solutions with a shared vision for the future of fiber networking. The combined business will offer a comprehensive portfolio for providing homes, businesses and 5G infrastructure with scalable, secure and assured fiber connectivity, paired with cloud-managed Wi-Fi connectivity and SaaS applications that optimize the performance of the network and improve the customer experience.

“We are in the early stages of an unprecedented investment cycle in fiber connectivity, especially in the U.S. and Europe, fueled by the demand for last-mile fiber access and middle-mile transport to provide high-speed connectivity to homes, businesses and future 5G infrastructure,” said ADTRAN Chairman and CEO Thomas Stanton. “By joining forces, our combined firm’s portfolio will better position us to capitalize on this highly compelling global opportunity. We expect the transaction will create significant long-term value for both companies’ stakeholders by increasing our scale and improving our ability to serve as a trusted supplier for customers worldwide.”

“The business combination is an outstanding opportunity to leverage the complementary nature of our customers and product portfolios and the compatibility of our companies’ businesses and culture,” said ADVA CEO Brian Protiva. “We are excited to join forces and create a world-class team with exceptional technology expertise and customer focus. Our shared vision and passion for innovative networking solutions will benefit our customers through an enhanced value proposition, including a fully integrated end-to-end architecture for enterprise, access and metro core markets.”

The companies also note that the combination will leverage its trusted supplier status to communications service providers, to create an expanded, secure and more-comprehensive portfolio for government networks and critical infrastructure. The combined company will continue to support all customers in its current markets and will continue to benefit from world-class R&D teams to help advance the next generation of fiber communications networks.

ACCELERATING GROWTH AND DRIVING VALUE CREATION

The combination of ADTRAN and ADVA is expected to create significant value for the shareholders of both companies, with approximately $52 million in pre-tax annual cost synergies realized within two years post-closing, driven by identified supply chain efficiencies and operating model optimization.

Importantly, the combination will create opportunities to better serve customers. This will enable the combined company to accelerate its growth profile by utilizing a broader regional presence and the enhanced cross-selling opportunities facilitated by complementary product lines.

TRANSACTION DETAILS

ADTRAN and ADVA will combine under a new holding company (which will be renamed ADTRAN Holdings, Inc. following the closing) pursuant to an all-stock exchange offer for 100% of ADVA’s outstanding shares.

Under the terms of the offer, each ADVA share will be exchanged for 0.8244 shares of common stock in the new holding company. The offer is equivalent to €14.98 per ADVA share based on ADTRAN’s 3-month VWAP as of August 27, 2021, representing a premium of 22% to ADVA’s 3-month VWAP for the same time period, an equity value of €789 million, and an enterprise value of €759 million for an implied multiple of 1.3x LTM Revenue. ADTRAN shares will be exchanged for shares in the new holding company on a one-for-one basis. At the closing, ADTRAN shareholders will own approximately 54% of the equity of the combined company and ADVA shareholders will own approximately 46%, assuming a tender of 100% of ADVA shares.

The new holding company will commence the public takeover offer after approval of the offer document by the German Federal Financial Supervisory Authority (Bundesanstalt fuer Finanzdienstleistungsaufsicht / BaFin), which ADTRAN anticipates occurring in November 2021. The offer will be subject to certain closing conditions, including a minimum acceptance threshold of 70% of the outstanding shares in ADVA, majority approval by ADTRAN shareholders, regulatory approvals, and other customary closing conditions.

The business combination agreement has been approved unanimously by the ADTRAN Board of Directors and the ADVA Management and Supervisory Boards. The transaction also has the strong support of ADVA’s largest shareholder, Egora, which has entered into an irrevocable commitment to tender into the offer shares representing 13.7% of ADVA’s outstanding shares.

The companies anticipate completing the transaction during the second or third quarter of 2022, subject to receipt of required regulatory approvals, as well as satisfaction of other customary closing conditions. The new holding company, in coordination with the ADVA Management and Supervisory Boards, intends to pursue a delisting and squeeze-out of the ADVA shares, following settlement of the offer or at a later date, depending on the new holding company’s shareholding in ADVA, prevailing market conditions and other economic considerations.

THE COMBINED COMPANY

The combined company will be named ADTRAN Holdings, Inc.. Its global headquarters will be located in Huntsville, AL and its European headquarters will be in Munich, Germany.

The new management team and Board of Directors will have a balanced mix of executives from both companies. ADTRAN’s Chairman and CEO, Tom Stanton, will serve in the same capacity following the close of the transaction. ADVA’s CEO, Brian Protiva, will transition into the role of Executive Vice Chairman. ADTRAN’s CFO, Mike Foliano, will remain in his current role and ADVA’s CTO, Christoph Glingener, will serve in the same capacity for the combined entity.

2

The Board of Directors of the combined company will comprise 9 directors, 6 of whom will be directors designated by ADTRAN and 3 of whom will be directors designated by ADVA.

The combined company will be dual-listed on the NASDAQ and Frankfurt Stock Exchange.

ADVISORS

BofA Securities is acting as exclusive financial advisor to ADTRAN, and Jefferies is acting as exclusive financial advisor to ADVA. Kirkland & Ellis LLP is serving as legal counsel to ADTRAN, and Hogan Lovells International LLP is serving as legal counsel to ADVA.

(“Acorn HoldCo”) may be unable to achieve expected synergies or that it may take longer or be more costly than expected to achieve those synergies; the risk of fluctuations in revenue due to lengthy sales and approval process required by major and other service providers for new products; the risk posed by potential breaches of information systems and cyber-attacks; the risks that ADTRAN, ADVA or the post-combination company may not be able to effectively compete, including through product improvements and development; and such other factors as are set forth in ADVA’s annual and interim financial reports made publicly available and ADTRAN’s and Acorn HoldCo’s public filings made with the SEC from time to time, including but not limited to those described under the headings “Risk Factors” and “Forward-Looking Statements” in ADTRAN’s Form 10-K for the fiscal year ended December 31, 2020 and ADTRAN’s Form 10-Q for the quarterly period ended June 30, 2021, which are available via the SEC’s website at www.sec.gov. The foregoing list of risk factors is not exhaustive. These risks, as well as other risks associated with the contemplated business combination, will be more fully discussed in the proxy statement/prospectus and the offering prospectus that will be included in the Registration Statement on Form S-4 that will be filed with the SEC and in an offering document and/or any prospectuses or supplements to be filed with BaFin in connection with the contemplated business combination. In light of these risks, uncertainties and assumptions, the events described in the forward-looking statements might not occur or might occur to a different extent or at a different time than ADTRAN, ADVA or Acorn HoldCo has described. All such factors are difficult to predict and beyond our control. All forward-looking statements included in this document are based upon information available to ADTRAN, ADVA and Acorn HoldCo on the date hereof, and each of ADTRAN, ADVA and Acorn HoldCo disclaims and does not undertake any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. It should also be noted that projected financial information for the combined businesses of ADTRAN and ADVA is based on management’s estimates, assumptions and projections and has not been prepared in conformance with the applicable accounting requirements of Regulation S-X relating to pro forma financial information, and the required pro forma adjustments have not been applied and are not reflected therein. None of this information should be considered in isolation from, or as a substitute for, the historical financial statements of ADTRAN or ADVA. Important risk factors could cause actual future results and other future events to differ materially from those currently estimated by management, including, but not limited to, the risks that: a condition to the closing of the proposed business combination may not be satisfied; a regulatory approval that may be required for the proposed business combination is delayed, is not obtained or is obtained subject to conditions that are not anticipated; ADTRAN is unable to achieve the synergies and value creation contemplated by the proposed business combination; ADTRAN is unable to promptly and effectively integrate ADVA’s businesses; management’s time and attention is diverted on transaction related issues; disruption from the transaction makes it more difficult to maintain business, contractual and operational relationships; the credit ratings of the combined company declines following the proposed business combination; legal proceedings are instituted against ADTRAN, ADVA or the combined company; ADTRAN, ADVA or the combined company is unable to retain key personnel; and the announcement or the consummation of the proposed business combination has a negative effect on the market price of the capital stock of ADTRAN and common shares of ADVA or on ADTRAN’s and ADVA’s operating results. No assurances can be given that any of the events anticipated by the forward-looking statements will transpire or occur, or if any of them do occur, what impact they will have on the results of operations, financial condition or cash flows of ADTRAN or ADVA. Should any risks and uncertainties develop into actual events, these developments could have a material adverse effect on the proposed transaction and/or ADTRAN or ADVA, ADTRAN’s ability to successfully complete the proposed transaction and/or realize the expected benefits from the proposed transaction. You are cautioned not to rely on ADTRAN’s and ADVA’s forward-looking statements. These forward-looking statements are and will be based upon management’s then-current views and assumptions regarding future events and operating performance, and are applicable only as of the dates of such statements. Neither ADTRAN nor ADVA assumes any duty to update or revise forward-looking statements, whether as a result of new information, future events or otherwise, as of any future date.

Germany

incorporated under German law and registered with the commercial register of the local court of Jena, Germany, under HRB 508155

(WKN: 510300 / ISIN: DE0005103006)

On 30 August 2021, Acorn HoldCo, Inc. (the “Bidder”), a newly formed corporation incorporated under the laws of Delaware, United States, and a wholly-owned subsidiary of ADTRAN, Inc., a company incorporated under the laws of Delaware, United States with registered address in Wilmington, United States (“ADTRAN”), decided to make a voluntary public takeover offer (freiwilliges öffentliches Übernahmeangebot) to the shareholders of ADVA Optical Networking SE (the “Company”) for the acquisition of all non-par value bearer shares in the Company (ISIN DE0005103006), each share representing a proportionate amount of EUR 1.00 of the share capital of the Company, (the “ADVA Shares”) in the form of an exchange offer (the “Exchange Offer”).

As consideration for the tendered ADVA Shares, the Bidder offers for each tendered ADVA Share 0.8244 common shares in the Bidder (the “HoldCo Shares”).

Shortly prior to the settlement of the Exchange Offer, ADTRAN shall become a wholly-owned subsidiary of the Bidder through a merger of ADTRAN as surviving entity and an indirect wholly-owned subsidiary of the Bidder (“MergerSub”) in accordance with applicable Delaware law (the “Merger”). The Merger will be subject to the launch of the Exchange Offer and satisfaction of all offer conditions (as described below) of the Exchange Offer. Upon completion of the Exchange Offer and the Merger (together, the “Business Combination”), the Bidder will become the holding company for the Company and ADTRAN. ADTRAN shareholders would own approximately 54% and ADVA shareholders would own approximately 46% of the equity of the Bidder, assuming a tender of 100% of ADVA Shares.

The Exchange Offer will be subject to certain closing conditions, including the approval by a majority of ADTRAN shareholders, a minimum acceptance threshold of 70% of all ADVA Shares outstanding, antitrust approvals and foreign investment control clearances, the declaration of effectiveness by the U.S. Securities and Exchange Commission of the Registration Statement on Form S-4 regarding the issuance of HoldCo Shares, as well as other customary offer conditions.

The Bidder has concluded an irrevocable undertaking with EGORA Holding GmbH and its wholly-owned subsidiary EGORA Investments GmbH, under which such shareholders have committed to accept the Exchange Offer for in total 7,000,000 ADVA Shares which are held by them (representing approximately 13.7% of the Company’s share capital). The irrevocable undertaking qualifies as an “instrument” within the meaning of Section 38 German Securities Trading Act (Wertpapierhandelsgesetz, WpHG).

Today, ADTRAN, MergerSub, the Bidder and the Company entered into a business combination agreement regarding the principal terms and conditions of the Business Combination and the Exchange Offer as well as the mutual intentions and understandings with regard to the future collaboration.

The offer document for the Exchange Offer (in the German language and a non-binding English translation thereof) and other information relating to the Exchange Offer will be published on the internet at www.acorn-offer.com.

Important Notice

The Exchange Offer itself as well as its terms and conditions and further provisions concerning the Exchange Offer will be set out in the offer document in detail after the German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht) has permitted the publication of the offer document. Investors and holders of shares in the Company are strongly advised to thoroughly read the offer document and all other relevant documents regarding the Exchange Offer upon their availability since they will contain important information.

The Exchange Offer will exclusively be subject to the laws of the Federal Republic of Germany and certain applicable provisions of securities laws of the United States of America. Any agreement that is entered into as a result of accepting the Exchange Offer will be exclusively governed by the laws of the Federal Republic of Germany and is to be interpreted in accordance with such laws.
