Who is offering to buy my securities?

Our name is King Acquisition Co. We are a Delaware corporation formed for the purpose of making this tender offer for all of the common stock of Ikanos. We are a wholly-owned subsidiary of Parent. See Section 8 — “Certain Information Concerning Purchaser and Parent.”

What securities are you offering to purchase?

We are offering to purchase all of the outstanding common stock, par value $0.001 per share, of Ikanos on the terms and subject to the conditions set forth in this Offer to Purchase and the related Letter of Transmittal. We refer to one share of Ikanos’s outstanding common stock, par value $0.001 per share, as a “Share.” See the “Introduction.”

Why are you making the Offer?

We are making the Offer pursuant to the Merger Agreement, in order to acquire control of, and ultimately after Purchaser merges with and into Ikanos (the “Merger”), the entire equity interest in, Ikanos, while allowing Ikanos’s stockholders an opportunity to receive the Offer Price as soon as practicable after the Expiration Date by tendering their Shares pursuant to the Offer. If the Offer is consummated, subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, Parent and Ikanos will consummate the Merger immediately thereafter without any action by the stockholders of Ikanos in accordance with Section 251(h) of the DGCL. At the effective time of the Merger (the “Effective Time”), Ikanos will become a wholly-owned subsidiary of Parent. See Section 12 — “Purpose of the Offer and Plans for Ikanos.”

How much are you offering to pay for my securities, and what is the form of payment? Will I have to pay any fees or commissions?

We are offering to pay $2.75 per Share, net in cash, without interest (less any applicable withholding taxes). If you are the record holder of your Shares (i.e., a stock certificate evidencing the Shares has been issued to you or book entry has been issued to or entered for you and registered in your name) and you directly tender your Shares to us in the Offer, you will not have to pay brokerage fees or similar expenses. If you own Shares through a broker, dealer, commercial bank, trust company or other nominee, and your broker, dealer, commercial bank, trust company or other nominee tenders your Shares on your behalf, they may charge you a fee for doing so. You should consult your broker, dealer, commercial bank, trust company or other nominee to determine whether any charges will apply. See the “Introduction.”

Do you have the financial resources to pay for the Shares?

Yes. We estimate that we will need approximately $49 million to purchase all of the issued and outstanding Shares and to pay related fees and expenses. QUALCOMM Incorporated and/or Parent will provide us with sufficient funds to purchase all Shares validly tendered in the Offer and will provide funding for our acquisition of the remaining Shares in the Merger. QUALCOMM Incorporated and Parent expect to fund such cash requirements from available cash on hand.

Is the Offer subject to any financing condition?

No. The Offer is not subject to any financing condition.

Is your financial condition relevant to my decision to tender in the Offer?

We do not believe that our financial condition is relevant to your decision whether to tender your Shares and accept the Offer because:

Pursuant to the Merger Agreement, the parties have agreed on the terms and conditions of the Offer and, following consummation of the Offer, the Merger of Purchaser with and into Ikanos. See Section 11 — “The Transaction Documents.”

Lax, George Pavlov, James Smaha, Omid Tahernia, Dennis Bencala and Debajyoti Pal (together, the “Supporting Stockholders”) have entered into tender and support agreements with us and Parent pursuant to which, among other matters, the Supporting Stockholders have agreed to tender all Shares now held or hereafter acquired by them in the Offer. As of August 5, 2015, the Supporting Stockholders owned an aggregate of approximately 58.2% of the outstanding shares of common stock of Ikanos. See Section 11 — “The Transaction Documents — Certain Other Agreements — Tender and Support Agreement.”

How long do I have to decide whether to tender in the Offer?

The Offer is currently scheduled to expire at the “Expiration Time” which is 12:01 a.m. (Eastern Time), on September 17, 2015, unless the Offer is extended, in which event the “Expiration Time” will mean the latest time and date at which the Offer, as so extended, will expire. The date on which the Expiration Time occurs is referred to herein as the “Expiration Date.”

The Offer is conditioned upon, among other matters:

3

Table of Contents

We and Parent may waive any condition, in whole or in part, other than the Minimum Condition, at any time and from time to time, without Ikanos’s consent. See Section 15 — “Conditions of the Offer.”

Can the Offer be extended, and if so, under what circumstances can or will the Offer be extended?

Yes, the Offer can be extended. In some cases, we are required to extend the Offer beyond the initial Expiration Date, but in no event will we be required to extend the Offer beyond February 5, 2016 (the “End Date”). Pursuant to the Merger Agreement, we are required to extend the Offer:

If we extend the Offer, such extension will extend the time that you will have to tender your Shares. See Section 1 — “Terms of the Offer.”

How will I be notified if the Offer is extended?

If we decide to extend the Offer, we will inform the Depositary of that fact and will make a public announcement of the extension, no later than 9:00 a.m. (Eastern Time) on the next business day after the date the Offer was scheduled to expire. See Section 1 — “Terms of the Offer.”

If I tender my Shares, when and how will I get paid?

If the conditions to the Offer as set forth in Section 15 — “Conditions of the Offer” are satisfied or waived and we consummate the Offer and accept your Shares for payment, we will pay you an amount equal to the number of Shares you tendered multiplied by $2.75 in cash without interest (and less any amounts required to be deducted and withheld under any applicable tax law) promptly following the expiration of the Offer (but in no event more than three business days thereafter). See Section 1 —“Terms of the Offer” and Section 2 —“Acceptance for Payment and Payment of Shares.”

Table of Contents

How do I tender my Shares?

If you desire to tender all or any portion of your Shares in the Offer, this is what you must do:

Until what time can I withdraw previously tendered Shares?

You can withdraw some or all of the Shares that you tender in the Offer at any time prior to the expiration of the Offer, and following such expiration, you can withdraw them unless and until we accept Shares for payment as provided herein. Once we accept Shares for payment, you will no longer be able to withdraw them. See Section 4 — “Withdrawal Rights.”

How do I withdraw previously tendered Shares?

To withdraw Shares, you or your nominee must deliver a written notice of withdrawal, which includes all required information, to the Depositary while you have the right to withdraw the Shares. If you tendered your Shares by giving instructions to a broker, dealer, commercial bank, trust company or other nominee, you must instruct such nominee to arrange for the proper withdrawal of your Shares. See Section 4 — “Withdrawal Rights.”

What will happen to stock options, Shares, restricted stock units, SARs and warrants in the Offer?

The Offer is being made only for Shares, and not for options to purchase Shares (“Ikanos Options”), restricted stock units with respect to Shares (“Ikanos RSUs”) or stock appreciation rights (“Ikanos SARs”) issued pursuant to Ikanos’s Amended and Restated 1999 Stock Option Plan, Amended and Restated 2004 Employee Stock Purchase Plan and the 2014 Stock Incentive Plan (the “Ikanos Equity Plans”). Holders of Ikanos Options or Ikanos RSUs, but not Ikanos SARs, may participate in the Offer only if they first exercise such Ikanos Options (to the extent exercisable) or become vested in such Ikanos RSUs which are then settled in Shares in accordance with the terms of the applicable Ikanos Equity Plan and other applicable Ikanos award agreements and tender the Shares, if any, issued upon such exercise or in connection with such vesting and settlement. Any such exercise or settlement needs to be completed sufficiently in advance of the Expiration Date to assure that the holder of such outstanding Ikanos Options or Ikanos RSUs will have sufficient time to comply with the procedures for tendering Shares described below in Section 3 — “Procedures for Tendering Shares.”

As of the Effective Time, each outstanding and unexercised Ikanos Option subject to time-based vesting (“Time-based Ikanos Option”), whether or not vested, shall be cancelled and converted into the right to receive cash in an amount equal to the product of (i) the total number of Shares subject to such Time-based Ikanos

5

Table of Contents

Option immediately prior to the Effective Time, multiplied by (ii) the excess, if any, of (x) the Offer Price over (y) the exercise price payable per Share under such Time-based Ikanos Option. As of the Effective Time, each unvested Ikanos stock option that is subject to performance-based vesting (“Performance-based Ikanos Option”) shall be cancelled for no consideration. As of August 5, 2015, 39,800 Time-based Ikanos Options have a per share exercise price greater than the Offer Price. All other outstanding and unexercised Ikanos stock options will be cancelled for no consideration.

All outstanding and unexercised Ikanos SARs have a per share exercise price greater than the Offer Price. As a result, all outstanding and unexercised Ikanos SARs will be cancelled upon the consummation of the Merger and the holders of such Ikanos SARs will not have any right to receive any consideration in respect thereof.

In addition, each of the warrants issued by Ikanos to Alcatel-Lucent USA, Inc. on September 29, 2014 and on December 10, 2014, each of which was amended on April 30, 2015 (the “Ikanos Warrants”), have a per share exercise price equal to the Offer Price. As a result, all outstanding Ikanos Warrants will be cancelled upon the consummation of the Merger and the holders of such Ikanos Warrants will not have any right to receive any consideration in respect thereof.

Additionally, as the Effective Time, each outstanding Ikanos RSU, whether or not vested, will be cancelled and converted into the right to receive cash in an amount equal to the product of (i) the total number of Shares issuable in settlement of such Ikanos RSU immediately prior to the Effective Time multiplied by (ii) the Offer Price. See Section 11 — “The Transaction Documents — Summary of the Merger Agreement.”

When and how will I be paid for my tendered Shares?

Subject to the terms and conditions of the Offer, we will pay for all Shares validly tendered that have not been withdrawn promptly following the later of the expiration of the Offer and the satisfaction or waiver of the Offer Conditions to the Offer set forth in Section 15 — “Conditions of the Offer.” However, we do reserve the right in our sole discretion and subject to applicable law and the terms of the Merger Agreement, to delay the acceptance for payment for Shares until satisfaction of all conditions to the Offer. See Section 2 — “Acceptance for Payment and Payment for Shares.”

We will pay for your Shares by depositing the Offer Price with the Depositary, which will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. In all cases, payment for tendered Shares will be made only after timely receipt by the Depositary of certificates for such Shares (or of a confirmation of a book-entry transfer of such shares as described in Section 3 — “Procedures for Tendering Shares — Book-Entry Delivery”), a properly completed and duly executed Letter of Transmittal (or facsimile thereof) and any other required documents. See Section 2 — “Acceptance for Payment and Payment for Shares.”

Will the Offer be followed by a merger if all the Shares are not tendered in the Offer?

Yes. If at least such number of Shares as satisfies the Minimum Condition are validly tendered and accepted for payment by us in the Offer, and the other conditions to the Merger are satisfied or waived (see Section 11 — “The Transaction Documents — Summary of the Merger Agreement — Conditions to the Merger”), then, in accordance with the terms of the Merger Agreement, we will complete the Merger without a vote of Ikanos’s stockholders pursuant to Section 251(h) of the DGCL.

Upon the successful consummation of the Offer, will Ikanos continue as a public company?

No. Following the purchase of the Shares in the Offer, we, Parent and Ikanos expect to consummate the Merger as soon as practicable in accordance with Section 251(h) of the DGCL, after which Ikanos will continue as the surviving corporation in the Merger and as a wholly-owned subsidiary of Parent (the “Surviving

6

Table of Contents

Corporation”), and the Shares will no longer be publicly traded. Following consummation of the Merger, we intend to cause Ikanos to be delisted from The NASDAQ Capital Market (“NASDAQ”) and deregistered under the Securities Exchange Act of 1934, as amended, and the regulations thereunder (the “Exchange Act”). See Section 13 — “Certain Other Effects.”

Will there be a subsequent offering period?

No. Pursuant to Section 251(h) of the DGCL and due to the obligations of Parent and Ikanos under the Merger Agreement, we expect the Merger to occur following the Acceptance Time without a subsequent offering period. See Section 1 — “Terms of the Offer.”

If I decide not to tender my Shares pursuant to the Offer, how will the Offer affect my Shares?

Following the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, Parent and Ikanos will consummate the Merger as soon as practicable. If the Merger is consummated, then stockholders who did not tender their Shares pursuant to the Offer (other than those properly exercising their appraisal rights in accordance with Section 262 of the DGCL) will receive the same amount of cash per Share that they would have received had they tendered their Shares pursuant to the Offer. Therefore, if the Merger takes place and you do not perfect your appraisal rights, the only difference to you between tendering your Shares pursuant to the Offer and not tendering your Shares pursuant to the Offer would be that, if you tender your Shares, you may be paid sooner. No interest will be paid for Shares acquired in the Offer or the Merger. Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger.

Are appraisal rights available in either the Offer or the Merger?

Appraisal rights are not available in connection with the Offer. However, appraisal rights will be available in the Merger to holders of Shares that are not tendered or voted in favor of the Merger and who comply with the applicable requirements of Delaware law. See Section 16 — “Certain Legal Matters; Regulatory Approvals.”

What is the market value of my Shares as of a recent date?

On August 5, 2015, the last full trading day before the public announcement of the execution of the Merger Agreement, the last reported sales price of Ikanos common stock reported on NASDAQ was $1.75 per Share. Therefore, the Offer Price of $2.75 per Share represents a premium of approximately 57.1% over the August 5, 2015 closing stock price, a 51.9% premium over the average trading price over the five trading days ending August 5, 2015 and a 38.8% premium over the average trading price over the 30 trading days ending August 5, 2015. Please obtain a recent quotation for your Shares prior to deciding whether or not to tender. See Section 6 — “Price Range of Shares; Dividends.”

What are the material U.S. federal income tax consequences of participating in the Offer or the Merger?

In general, the receipt of cash by you in exchange for your Shares pursuant to the Offer or the Merger will be a taxable transaction for U.S. federal income tax purposes and may also be a taxable transaction under applicable state, local, non-U.S. or other tax laws. You should consult your tax advisor about the tax consequences to you of participating in the Offer in light of your particular circumstances. See Section 5 — “Certain Material U.S. Federal Income Tax Considerations.”

Who can I talk to if I have questions about the Offer?

You can call D.F. King & Co., Inc., the Information Agent for the Offer, at 877-478-5044 (toll free). See the back cover of this Offer to Purchase.

To the Holders of Shares of Ikanos:

INTRODUCTION

We are offering to purchase all Shares of Ikanos, for the Offer Price, upon the terms and subject to the conditions set forth in the Offer to Purchase and the related Letter of Transmittal. Stockholders who are record owners of their Shares (i.e., a stock certificate evidencing the Shares has been issued to such stockholder or book entry has been issued to or entered for such stockholder and registered in such stockholder’s name) and who tender directly to Depositary, will not have to pay brokerage fees or commissions. Stockholders with Shares held in street name by a broker, dealer, commercial bank, trust company or other nominee should consult with their nominee to determine if the nominee charges any transaction fees. Except as set forth in Instruction 6 of the Letter of Transmittal, stockholders will not have to pay stock transfer taxes on the sale of Shares pursuant to the Offer. We will pay all charges and expenses of the Depositary and Information Agent incurred in connection with the Offer. See Section 17 — “Fees and Expenses.” References herein to “Qualcomm” shall mean Parent and Purchaser.

We are making the Offer pursuant to the Merger Agreement. The Merger Agreement provides, among other matters, that as soon as practicable after the consummation of the Offer and the satisfaction or waiver of the conditions set forth in the Merger Agreement, Purchaser will merge with and into Ikanos, with Ikanos continuing as the Surviving Corporation. At the Effective Time, each outstanding Share (other than (i) Shares held by Ikanos as treasury stock, (ii) Shares held by Parent, Purchaser or any other subsidiary of Parent, (iii) Shares held by a wholly-owned subsidiary of Ikanos, (iv) Shares irrevocably accepted for purchase pursuant to the Offer, or (v) Shares held by a holder who is entitled to demand and properly demands appraisal in accordance with Section 262 of the DGCL) will be converted into the right to receive cash equal to the amount of the Offer Price, without interest thereon, less any applicable withholding taxes. Stockholders who validly exercise appraisal rights under Delaware law will be entitled to receive a judicially determined fair value for their Shares, which value could be more or less than the consideration to be paid in the Merger. See Section 11 — “The Transaction Documents.”

The Ikanos Board has unanimously (i) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement, including the Offer and the Merger, are advisable, fair to and in the best interests of Ikanos and its stockholders; (ii) agreed that the Merger shall be subject to Section 251(h) of the DGCL; (iii) approved the execution, delivery and performance by Ikanos of the Merger Agreement and the consummation of the transactions contemplated therein, including the Offer and the Merger; and (iv) resolved to recommend that the holders of Shares accept the Offer and tender their Shares to Purchaser pursuant to the Offer.

Ikanos has agreed to file its Tender Offer Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”) with the SEC and disseminate the Schedule 14D-9 to holders of Shares, in each case as and to the extent required by applicable federal securities laws. The Schedule 14D-9 will include a more complete description of the Board’s reasons for authorizing and approving the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger, and holders of the Shares are encouraged to review the Schedule 14D-9 carefully. The Schedule 14D-9 also includes the procedures to demand appraisal in accordance with Section 262 of the DGCL.

The obligation of Purchaser to purchase Shares tendered in the Offer is subject to the satisfaction or waiver of a number of conditions set forth in the Merger Agreement, including, among other things, (i) there being validly tendered and not validly withdrawn prior to the Expiration Time (as defined below) that number of Shares (excluding Shares tendered pursuant to procedures for guaranteed delivery and not actually delivered prior to the Expiration Time) that when added to the Shares then owned by Purchaser represent one more than 50% of the sum of (A) the total number of Shares outstanding at the time of the expiration of the Offer plus (B) the aggregate number of Shares issuable upon conversion, settlement or exercise of all then outstanding Ikanos Warrants, options, benefit plans, obligations or securities convertible or exchangeable into Shares or other rights

to acquire or to be issued Shares (including all then outstanding Ikanos Options, Ikanos RSUs and Ikanos Warrants) from which Ikanos has received notices of conversion, settlement or exercise prior to the Expiration Date or which automatically convert, settle or exercise prior to the Acceptance Time (and as to which Shares have not yet been issued) (the “Minimum Condition”), (ii) the Antitrust Condition, (iii) the absence of a material adverse effect on Ikanos and (iv) certain other customary conditions. See Section 15 — “Conditions of the Offer.”

The Offer is being made only for Shares, and not for Ikanos Options, Ikanos RSUs or Ikanos SARs issued pursuant to the Ikanos Equity Plans. Holders of outstanding Ikanos Options or Ikanos RSUs, but not Ikanos SARs, may participate in the Offer only if they first exercise such Ikanos Options (to the extent exercisable) or become vested in such Ikanos RSUs which are then settled in Shares in accordance with the terms of the applicable Ikanos Equity Plan and other applicable Ikanos award agreements and tender the Shares, if any, issued upon such exercise or in connection with such vesting and settlement. Any such exercise or settlement needs to be completed sufficiently in advance of the Expiration Date to assure that the holder of such outstanding Ikanos Options or Ikanos RSUs will have sufficient time to comply with the procedures for tendering Shares described below in Section 3 — “Procedures for Tendering Shares.”

As of the Effective Time, each outstanding and unexercised Time-based Ikanos Option, whether or not vested, shall be cancelled and converted into the right to receive cash in an amount equal to the product of (i) the total number of Shares subject to such Time-based Ikanos Option immediately prior to the Effective Time, multiplied by (ii) the excess, if any, of (x) the Offer Price over (y) the exercise price payable per Share under such Time-based Ikanos Option. As of the Effective Time, each unvested Performance-based Ikanos Option will be cancelled for no consideration. As of August 5, 2015, 39,800 Time-based Ikanos Options have a per share exercise price greater than the Offer Price. All other outstanding and unexercised Ikanos stock options will be cancelled for no consideration.

All outstanding and unexercised Ikanos SARs have a per share exercise price greater than the Offer Price. As a result, all outstanding and unexercised Ikanos SARs will be cancelled upon the consummation of the Merger and the holders of Ikanos SARs will not have any right to receive any consideration in respect thereof.

Additionally, as the Effective Time, each outstanding Ikanos RSU, whether or not vested, will be cancelled and converted into the right to receive cash in an amount equal to the product of (i) the total number of Shares issuable in settlement of Ikanos RSU immediately prior to the Effective Time multiplied by (ii) the Offer Price.

According to Ikanos, as of the close of business on August 5, 2015, there were (a) 17,228,613 issued and outstanding Shares, (b) 2,943,661 Shares subject to issuance pursuant to Ikanos Options, (c) 76,795 Shares estimated to be subject to outstanding purchase rights under the lkanos Amended and Restated 2004 Employee Stock Purchase Plan (the “Ikanos ESPP”) (assuming that the closing price per Share as reported on the purchase date for the current offering period was equal to the Offer Price), (d) 1,166,448 Shares subject to or otherwise deliverable in connection with outstanding Ikanos RSUs and (e) 473,684 Shares subject to issuance pursuant to the Ikanos Warrants. Based upon the foregoing and assuming that (i) no other Shares were or are issued after August 5, 2015 and (ii) no Ikanos Options, Ikanos RSUs or other equity-based awards denominated in Shares have been granted or have expired after August 5, 2015, the Minimum Condition would be satisfied if at least 8,614,307 Shares are tendered in the Offer, assuming Ikanos did not and does not receive notices of exercise with respect to any Ikanos Options or Ikanos Warrants prior to the expiration of the Offer and no Ikanos RSUs vest prior to the expiration of the Offer. The actual number and percentage of outstanding Shares that are required to be tendered to satisfy the Minimum Condition will depend on the actual number of Shares outstanding at the Expiration Date.

Smaha, Omid Tahernia, Dennis Bencala and Debajyoti Pal (together, the “Supporting Stockholders”) have entered into tender and support agreements with us and Parent pursuant to which, among other matters, the Supporting Stockholders have agreed to tender all Shares now held or hereafter acquired by them in the Offer. As of August 5, 2015 the Supporting Stockholders owned an aggregate of approximately 58.2% of the outstanding shares of common stock of Ikanos. See Section 11 — “The Transaction Documents — Certain Other Agreements — Tender and Support Agreement.”

The Merger will be governed by Section 251(h) of the DGCL. Accordingly, after the consummation of the Offer and subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement, we, Parent and Ikanos will cause the Merger to become effective as soon as practicable without a meeting of stockholders of Ikanos in accordance with Section 251(h) of the DGCL. Following the Merger, our directors and officers will be the directors of the Surviving Corporation.

Appraisal rights are not available to the holders of Shares in connection with the Offer. However, if the Merger is consummated, the holders of Shares immediately prior to the Effective Time who (i) did not tender their Shares in the Offer, (ii) follow the procedures set forth in Section 262 of the DGCL and (iii) do not thereafter withdraw their demand for appraisal of such Shares or otherwise lose their appraisal rights, in each case in accordance with the DGCL, will be entitled to have their Shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such Shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with a fair rate of interest, as determined by such court. The “fair value” could be higher or lower than, or the same as, the Offer Price or the consideration payable in the Merger (which is equivalent in amount to the Offer Price). See Section 16 — “Certain Legal Matters; Regulatory Approvals — Appraisal Rights.”

This Offer to Purchase and the related Letter of Transmittal contain important information, and you should read carefully both in their entirety before you make a decision with respect to the Offer.

THE OFFER

Upon the terms and subject to the conditions to the Offer (including, if the Offer is extended or amended, the terms and conditions of such extension or amendment), as soon as practicable after the Expiration Date, we will (and Parent will cause us to) accept for payment and promptly thereafter pay for all Shares validly tendered and not properly withdrawn prior to the Expiration Date.

The Offer is not subject to any financing condition. The Offer is subject to the conditions set forth in Section 15 — “Conditions of the Offer,” which include, among other matters, satisfaction of the Minimum Condition and the Antitrust Condition.

There will not be a subsequent offering period for the Offer. Pursuant to the Merger Agreement, subject to the satisfaction or waiver of the conditions to the Merger set forth in the Merger Agreement, we, Parent and Ikanos will cause the Merger to become effective within three business days of the satisfaction or waiver of such conditions. Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. We do not expect there to be a significant period of time between the consummation of the Offer and the consummation of the Merger.

The Merger Agreement separately provides that we may extend the Offer beyond the initial Expiration Date. If any Offer Condition is not satisfied and has not been waived, Purchaser may, in its discretion (and without the consent of Ikanos or any other person), extend the Offer on one or more occasions, for an additional period of up to ten business days per extension, to permit such Offer Condition to be satisfied. Purchaser will extend the Offer from time to time for: (A) the minimum period required by any law, interpretation or position of the SEC or its staff or NASDAQ or its staff, in each case, applicable to the Offer and (B) periods of up to 15 business days per extension until the Antitrust Condition shall have been satisfied. In addition, if, as of the scheduled Expiration Date, any Offer Condition is not satisfied and has not been waived, at the request of Ikanos, Purchaser will extend the Offer on one occasion for an additional period of up to ten business days, to permit such Offer Condition to be satisfied; provided, however, that in no event shall Purchaser: (1) be required to extend the Offer beyond the earliest to occur of (x) the valid termination of the Merger Agreement and (y) February 5, 2016; or (2) be permitted to extend the Offer beyond February 5, 2016 without the prior written consent of Ikanos.

If we extend the Offer, are delayed in our acceptance for payment of Shares, are delayed in payment after the Acceptance Time or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may retain tendered Shares on our behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in this Offer to Purchase under Section 4 — “Withdrawal Rights.” However, our ability to delay the payment for Shares that we have accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires us to promptly pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer. Subject to the applicable rules and regulations of the SEC and the provisions of the Merger Agreement, Parent and Purchaser each expressly reserves the right to increase the Offer Price or to make any other changes in the terms and conditions of the Offer; provided that, unless otherwise provided in the Merger Agreement or previously approved by Ikanos in writing, Parent and Purchaser will not: (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) decrease the maximum number of Shares sought to be purchased in the Offer, (iv) impose conditions to the Offer in addition to the Offer Conditions, (v) amend or modify any of the Offer Conditions in a manner that adversely affects holders of Shares generally in their capacity as such or (vi) amend, modify or waive the Minimum Condition.

If we make any material change in the terms of or information concerning the Offer or waive a material condition of the Offer, we will extend the Offer, if required by applicable law, for a period sufficient to allow you to consider the amended terms of the Offer. In a published release, the SEC has stated that in its view the waiver

11

Table of Contents

of conditions such as the Minimum Condition or the Antitrust Condition is a material change in the terms of an offer and that an offer should remain open for a minimum of five business days from the date a material change is first published, sent or given to stockholders, and that if a material change directly relates to price and share levels, a minimum of ten business days may be required to allow adequate dissemination and investor response.

If we increase the consideration to be paid for Shares pursuant to the Offer, we will pay such increased consideration for all Shares that are purchased pursuant to the Offer.

Any extension, delay, termination, waiver or amendment of the Offer will be followed as promptly as practicable by a public announcement thereof. Without limiting the manner in which we may choose to make any public announcement, we will have no obligation (except as otherwise required by applicable law) to publish, advertise or otherwise communicate any such public announcement. In the case of an extension of the Offer, we will make a public announcement of such extension no later than 9:00 a.m., Eastern Time, on the next business day after the previously scheduled Expiration Time.

Ikanos has provided us with its stockholder list and security position listings for the purpose of disseminating the Offer to holders of Shares. We will send this Offer to Purchase, the Letter of Transmittal and other related documents to record holders of Shares and to brokers, dealers, banks, trust companies and other nominees whose names appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of Shares.

Upon the terms and subject to the conditions of the Offer, we will accept for payment and pay for all Shares validly tendered and not properly withdrawn prior to the Expiration Time. Notwithstanding the foregoing, subject to any applicable rules and regulations of the SEC (including Rule 14e-1(c) under the Exchange Act), we reserve the right, in our sole discretion and subject to applicable law, to delay the acceptance for payment or payment for Shares until satisfaction of all conditions to the Offer. For information with respect to approvals that we are or may be required to obtain prior to the completion of the Offer, see Section 16 — “Certain Legal Matters; Regulatory Approvals.”

We will pay for Shares accepted for payment pursuant to the Offer by depositing the Offer Price with the Depositary, which will act as your agent for the purpose of receiving payments from us and transmitting such payments to you. Upon the deposit of such funds with the Depositary, our obligation to make such payment shall be satisfied, and tendering stockholders must thereafter look solely to the Depositary for payment of amounts owed to them by reason of the acceptance for payment of Shares pursuant to the Offer.

In all cases, payment for Shares accepted for payment will be made only after timely receipt by the Depositary of (i) certificates for such Shares (or of a confirmation of a book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer Facility (as defined in Section 3 — “Procedures for Tendering Shares — Book-Entry Delivery”)); (ii) a properly completed and duly executed Letter of Transmittal (or a manually signed facsimile thereof), with any required signature guarantees (or in connection with a book-entry transfer, an Agent’s Message (as defined in Section 3 — “Procedures for Tendering Shares — Book-Entry Delivery”)); and (iii) any other required documents. For a description of the procedure for tendering Shares pursuant to the Offer, see Section 3 — “Procedures for Tendering Shares.” Accordingly, payment may be made to tendering stockholders at different times if delivery of the Shares and other required documents occurs at different times. Under no circumstances will we pay interest on the consideration paid for Shares pursuant to the Offer, regardless of any extension of the Offer or any delay in making such payment.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by us in our sole discretion. We reserve the absolute right to reject any and all tenders determined by us not to be in proper form or the acceptance for payment of which may, in the opinion of our counsel, be unlawful.

Table of Contents

Shares tendered by a Notice of Guaranteed Delivery will not be deemed validly tendered for purposes of satisfying the Minimum Condition unless and until Shares underlying such Notice of Guaranteed Delivery are delivered to the Depositary.

For purposes of the Offer, we shall be deemed to have accepted for payment tendered Shares when, as and if we give oral or written notice of our acceptance to the Depositary.

If we do not accept for payment any Shares tendered pursuant to the Offer for any reason, or if you submit certificates for more Shares than are tendered, we will return certificates for such unpurchased or untendered Shares (or, in the case of Shares delivered by book-entry transfer, such Shares will be credited to an account maintained at the Book-Entry Transfer Facility (as defined below) or in the case of Shares held in a nominee account by the Depositary, such Shares will be returned to the nominee account) without expense to you, promptly following the expiration, termination or withdrawal of the Offer.

We reserve the right to transfer or assign, in whole or from time to time in part, to one or more of our affiliates the right to purchase Shares tendered pursuant to the Offer, but any such transfer or assignment will not relieve us of our obligations under the Offer or prejudice your rights to receive payment for Shares validly tendered and accepted for payment.

Except as set forth below, to tender Shares in the Offer, either (a) the Depositary must receive on or prior to the Expiration Time at one of its addresses set forth on the back cover of this Offer to Purchase (i) a Letter of Transmittal (or a manually signed facsimile thereof), properly completed and signed, together with any required signature guarantees, or an Agent’s Message (as defined below) in connection with a book-entry delivery of Shares, and any other documents that the Letter of Transmittal requires and (ii) certificates for the Shares to be tendered or confirmation of the book-entry transfer of such Shares into the Depositary’s account at the Book-Entry Transfer Facility, or (b) you must comply with the guaranteed delivery procedures set forth below.

The method of delivery of Shares, the Letter of Transmittal and all other required documents, including through the Book–Entry Transfer Facility, is at the election and risk of the tendering stockholder and delivery will be deemed made only when actually received by the Depositary. If certificates for Shares are sent by mail, we recommend registered mail with return receipt requested, properly insured, in time to be received on or prior to the Expiration Time. In all cases, sufficient time should be allowed to ensure timely delivery.

The tender of Shares pursuant to any one of the procedures described above will constitute your acceptance of the Offer, as well as your representation and warranty that (i) you own the Shares being tendered within the meaning of Rule 14e-4 under the Exchange Act, (ii) the tender of such Shares complies with Rule 14e-4 under the Exchange Act, (iii) you have the full power and authority to tender, sell, assign, and transfer the Shares tendered, as specified in the Letter of Transmittal and (iv) when the Shares are accepted for payment by us, we will acquire good, valid, and unencumbered title thereto, free and clear of any liens, restrictions, charges or encumbrances and not subject to any adverse claims. Our acceptance for payment of Shares tendered by you pursuant to the Offer will constitute a binding agreement between us with respect to such Shares, upon the terms and subject to the conditions of the Offer.

Stockholders tendering their Shares according to the guaranteed delivery procedures set forth under Section 3 — “Procedures for Tendering Shares — Guaranteed Delivery” may do so using the Notice of Guaranteed Delivery circulated herewith, however, any Shares tendered pursuant to a Notice of Guaranteed Delivery and not actually delivered prior to the Effective Time will not count toward satisfaction of the Minimum Condition (as defined below).

13

Table of Contents

Book-Entry Delivery

The Depositary has established an account with respect to the Shares for purposes of the Offer at The Depository Trust Company (the “Book-Entry Transfer Facility”). Any financial institution that is a participant in the system of the Book-Entry Transfer Facility may deliver Shares by causing the Book-Entry Transfer Facility to transfer such Shares into the Depositary’s account in accordance with the procedures of the Book-Entry Transfer Facility. However, although delivery of Shares may be effected through book-entry transfer, either the Letter of Transmittal (or a manually signed facsimile thereof) properly completed and duly executed together with any required signature guarantees or an Agent’s Message in lieu of the Letter of Transmittal and any other required documents must, in any case, be received by the Depositary at one of its addresses set forth on the back cover of this Offer to Purchase on or prior to the Expiration Time, or the guaranteed delivery procedure described below must be complied with.

“Agent’s Message” means a message transmitted by the Book-Entry Transfer Facility to, and received by, the Depositary and forming a part of a book-entry confirmation stating that the Book-Entry Transfer Facility has received an express acknowledgment from the participant in the Book-Entry Transfer Facility tendering the Shares that are the subject of such book-entry confirmation that such participant has received and agrees to be bound by the terms of the Letter of Transmittal and that we may enforce that agreement against the participant.

Required documents must be transmitted to and received by the Depositary at one of its addresses set forth on the back cover page of this Offer to Purchase. Delivery of the Letter of Transmittal and any other required documents to the Book-Entry Transfer Facility does not constitute delivery to the Depositary.

Signature Guarantees

All signatures on a Letter of Transmittal must be guaranteed by a financial institution (including most banks, savings and loan associations, and brokerage houses) that is a member of a recognized Medallion Program approved by The Securities Transfer Association Inc., including the Securities Transfer Agents Medallion Program (“STAMP”), the Stock Exchange Medallion Program (“SEMP”), and the New York Stock Exchange, Inc. Medallion Signature Program (“MSP”) or any other “eligible guarantor institution” (as such term is defined in Rule 17Ad-15 under the Exchange Act) (each, an “Eligible Institution”), unless the Shares tendered are tendered (a) by a registered holder of Shares who has not completed the box labeled “Special Payment Instructions” on the Letter of Transmittal or (b) for the account of an Eligible Institution. See Instructions 1 and 5 of the Letter of Transmittal.

Guaranteed Delivery

If you wish to tender Shares pursuant to the Offer and cannot deliver such Shares and all other required documents to the Depositary prior to the Expiration Time or cannot complete the procedure for delivery by book-entry transfer on a timely basis, you may, nevertheless, tender such Shares if all of the following conditions are met:

14

Table of Contents

The Notice of Guaranteed Delivery may be delivered by hand or transmitted by facsimile transmission or mail to the Depositary and must include a guarantee by an Eligible Institution in the form set forth in such Notice. Any Shares tendered pursuant to a Notice of Guaranteed Delivery and not actually delivered prior to the Effective Time will not count toward satisfaction of the Minimum Condition.

Backup Withholding

To prevent federal “backup withholding” with respect to payment of the Offer Price of Shares purchased pursuant to the Offer, each Ikanos stockholder (including any Ikanos stockholder that tenders Shares into the Offer pursuant to the book-entry transfer procedures described above in this Section 3) must provide the Depositary with its correct taxpayer identification number or otherwise comply with applicable backup withholding rules and certification requirements. Each Ikanos stockholder should complete and sign the Internal Revenue Service (“IRS”) Form W-9 included with the Letter of Transmittal (or other applicable form such as the appropriate IRS Form W-8) in order to provide the information and certification necessary to avoid the imposition of backup withholding. See Instruction 8 set forth in the Letter of Transmittal and Section 5 — “Certain Material U.S. Federal Income Tax Considerations” of this Offer to Purchase for a more detailed discussion of backup withholding.

Appointment of Proxy

By executing a Letter of Transmittal, you irrevocably appoint our designees as your attorneys-in-fact and proxies in the manner set forth in the Letter of Transmittal to the full extent of your rights with respect to the Shares tendered and accepted for payment by us (and any and all other Shares or other securities issued or issuable in respect of such Shares on or after the date of the original Offer to Purchase). All such powers of attorney and proxies are irrevocable and coupled with an interest in the tendered Shares. Such appointment is effective only upon our acceptance for payment of such Shares. Upon such acceptance for payment, all prior powers of attorney and proxies and consents granted by you with respect to such Shares and other securities will, without further action, be revoked, and no subsequent powers of attorney or proxies may be given nor subsequent written consents executed (and, if previously given or executed, will cease to be effective). Upon such acceptance for payment, our designees will be empowered to exercise all your voting and other rights as they, in their sole discretion, may deem proper at any annual, special or adjourned meeting of Ikanos’s stockholders, by written consent or otherwise. We reserve the right to require that, in order for Shares to be validly tendered, immediately upon our acceptance for payment of such Shares, we are able to exercise full voting rights with respect to such Shares and other securities (including voting at any meeting of stockholders then scheduled or acting by written consent without a meeting).

The foregoing powers of attorney and proxies are effective only upon acceptance for payment of Shares pursuant to the Offer. The Offer does not constitute a solicitation of proxies, absent a purchase of Shares, for any meeting of Ikanos’s stockholders.

Determination of Validity

We will determine, in our sole discretion, all questions as to the form of documents and the validity, eligibility (including time of receipt), and acceptance for payment of any tender of Shares, and our determination shall be final and binding. We reserve the absolute right to reject any or all tenders of Shares that we determine not to be in proper form or the acceptance for payment of or payment for which may, in the opinion of our counsel, be unlawful. We also reserve the absolute right to waive any defect or irregularity in any tender of Shares, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities with respect to such tender have been cured or waived. None of us, the Depositary, the Information Agent, or any other person will be under any duty to give notification of any defect or irregularity in tenders or waiver of any such defect or irregularity or incur any liability for failure to give any such notification. Our interpretation of the terms and conditions of the Offer (including the Letter of Transmittal and the instructions thereto) will be final and binding.

Table of Contents

Except as otherwise provided in this Section 4, tenders of Shares made pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date. Thereafter, tenders of Shares are irrevocable, except that they may also be withdrawn after 60 days from the commencement of the Offer, unless such Shares have already been accepted for payment by us pursuant to the Offer.

For a withdrawal to be proper and effective, a written notice of withdrawal must be timely received by the Depositary at one of its addresses set forth on the back cover page of this Offer to Purchase. Any such notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the registered holder of such Shares, if different from that of the person who tendered such Shares. If Shares held as physical certificates, the certificates evidencing such Shares (“Share Certificates”) to be withdrawn have been delivered or otherwise identified to the Depositary, then, prior to the physical release of such Share Certificates, the serial numbers shown on such Share Certificates must be submitted to the Depositary and the signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution, unless such Shares have been tendered for the account of an Eligible Institution. If Shares have been tendered pursuant to the procedure for book-entry transfer as set forth in Section 3 — “Procedures for Tendering Shares — Book-Entry Delivery,” any notice of withdrawal must also specify the name and number of the account at The Depository Trust Company to be credited with the withdrawn Shares.

If we extend the Offer, are delayed in our acceptance for payment of Shares or are unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to our rights under the Offer, the Depositary may, nevertheless, on our behalf, retain tendered Shares, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in this Section 4 and as otherwise required by Rule 14e-1(c) under the Exchange Act.

Withdrawals of tendered Shares may not be rescinded, and any Shares properly withdrawn will thereafter be deemed not to have been validly tendered for purposes of the Offer. However, Shares that have been properly withdrawn may be re-tendered at any time prior to the Expiration Date by following one of the procedures described in Section 3 — “Procedures for Tendering Shares.”

All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by us in our sole discretion. We also reserve the absolute right to waive any defect or irregularity in the withdrawal of Shares by any stockholder, regardless of whether or not similar defects or irregularities are waived in the case of other stockholders. None of us, the Depositary, the Information Agent or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give any such notification.

The following is a discussion of certain material U.S. federal income tax consequences of the Offer and the Merger to Ikanos stockholders whose Shares are purchased pursuant to the Offer or whose Shares are converted into the right to receive cash in the Merger. This discussion is based on the Internal Revenue Code of 1986, as amended, applicable treasury regulations and administrative and judicial interpretations thereunder, each as in effect as of the date hereof, all of which may change, possibly with retroactive effect. Any such change, which may or may not be retroactive, could alter the U.S. federal income tax consequences to Ikanos stockholders as described herein. This discussion is not a comprehensive description of all U.S. federal income tax considerations that may be relevant to the Offer and the Merger. This discussion does not apply to Ikanos stockholders who receive cash pursuant to the exercise of appraisal rights. The discussion applies only to Ikanos stockholders that hold their Shares as capital assets for U.S. federal income tax purposes (generally, property held for investment), and may not apply to Shares received pursuant to the exercise of Ikanos Warrants, Ikanos Options, Ikanos RSUs or Ikanos SARs; Shares held as “qualified small business stock” or “section 1244 stock”; Shares held as part of a

16

Table of Contents

“straddle,” “hedge,” “conversion transaction,” constructive sale or other integrated transaction; Ikanos stockholders that purchase or sell Shares as part of a wash sale for tax purposes; Ikanos stockholders in special tax situations (including, but not limited to, dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, banks, real estate investment trusts, insurance companies, tax-exempt organizations, regulated investment companies, U.S. expatriates, “controlled foreign corporations” or “passive foreign investment companies”); or U.S. Holders (as defined below) whose functional currency is not the U.S. dollar. This discussion does not address any aspect of the U.S. alternative minimum or unearned income Medicare contribution tax, federal gift or estate tax, or state, local or non-U.S. taxation.

If a partnership (or entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Shares, the tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. Accordingly, partnerships that hold Shares and partners in such partnerships should consult their tax advisors with regard to the U.S. federal income tax consequences of exchanging Shares pursuant to the Offer or the Merger.

None of Ikanos, Parent, or Purchaser has requested or will request an advance ruling from the IRS as to the tax consequences of the Offer or the Merger, nor will counsel to Ikanos, Parent, or Purchaser render a tax opinion in connection with the Offer or the Merger. The IRS may take different positions concerning the tax consequences of the Offer or the Merger than those stated below, and such positions could be sustained.

This discussion does not address the tax consequences of acquisitions or dispositions of Shares outside the Offer and the Merger, or transactions pertaining to Ikanos Warrants, Ikanos Options, Ikanos RSUs, or Ikanos SARs.

THE MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES SET FORTH BELOW ARE BASED ON CURRENT LAW. BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH IKANOS STOCKHOLDER SHOULD CONSULT SUCH IKANOS STOCKHOLDER’S OWN TAX ADVISOR TO DETERMINE THE APPLICABILITY OF THE RULES DISCUSSED BELOW TO SUCH IKANOS STOCKHOLDER AND THE PARTICULAR TAX EFFECTS OF THE OFFER AND THE MERGER TO SUCH IKANOS STOCKHOLDER, INCLUDING THE APPLICATION AND EFFECT OF U.S. FEDERAL ESTATE AND GIFT, STATE, LOCAL, AND OTHER TAX LAWS.

U.S. Holders. For purposes of this discussion, the term “U.S. Holder” means a beneficial owner of Shares that is, for U.S. federal income tax purposes:

The receipt of cash for Shares pursuant to the Offer or the Merger will be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. Holder will recognize gain or loss in an amount equal to the difference between such U.S. Holder’s adjusted tax basis in such Shares sold pursuant to the Offer or converted into the right to receive cash in the Merger and the amount of cash received therefor. Gain or loss must be

17

Table of Contents

determined separately for each block of Shares (i.e., Shares acquired at the same cost in a single transaction) sold pursuant to the Offer or converted into the right to receive cash in the Merger. Such gain or loss will be capital gain or loss and will be long-term capital gain or loss if, on the date of sale (or, if applicable, the date of the Merger), such Shares were held for more than one year. Long-term capital gains recognized by a non-corporate U.S. Holder generally will be taxed at preferential rates. The deductibility of capital losses by a U.S. Holder is subject to limitations.

Non-U.S. Holders. For purposes of this discussion, the term “Non-U.S. Holder” means a beneficial owner of Shares that is not a U.S. Holder or an entity or arrangement classified as a partnership for U.S. federal income tax purposes.

In general, a Non-U.S. Holder will not be subject to U.S. federal income tax on gain recognized on Shares sold pursuant to the Offer or converted into the right to receive cash in the Merger unless:

With respect to the first bullet above, unless an applicable income tax treaty provides otherwise, Non-U.S. Holders are subject to U.S. federal income tax on effectively connected income on a net income basis at U.S. federal income tax rates applicable to U.S. persons. “Effectively connected” gains that are recognized by a Non-U.S. Holder that is treated as a corporation for U.S. federal income tax purposes also may be subject, under certain circumstances, to an additional “branch profits tax” at a 30% rate or at a lower rate if such Non-U.S. Holder is eligible for the benefits of an applicable income tax treaty that provides for a lower rate.

Gain realized by an individual Non-U.S. Holder described in the second bullet-point above will be subject to a flat 30% tax (or at a lower rate if such Non-U.S. Holder is eligible for the benefits of an applicable income tax treaty that provides for a lower rate), which gain may be offset by U.S.-source capital losses, even though the Non-U.S. Holder is not considered a resident of the United States.

In general, Ikanos would be a United States real property holding corporation if United States real property interests comprised (by fair market value) at least half of Ikanos’s total worldwide interests in real property plus Ikanos’s business assets. Ikanos believes that is has not been during the five-year period ending on the date of sale (or, if applicable, the date of the Merger), is not, and does not anticipate becoming, a United States real property holding corporation before the date of sale (or, if applicable, the date of the Merger) for U.S. federal income tax purposes. Even if Ikanos were treated as a United States real property holding corporation, such treatment will not cause gain realized by a Non-U.S. Holder on a disposition of Shares to be subject to U.S. federal income tax so long as (1) the Non-U.S. Holder owned, directly, indirectly, and constructively, no more than 5% of the Shares at all times within the shorter of (i) the five-year period preceding the date of sale (or, if applicable, the date of the Merger) or (ii) the Non-U.S. Holder’s holding period and (2) the Shares are regularly traded on an established securities market.

Information Reporting and Backup Withholding. Payments made to certain Ikanos stockholders in connection with the Offer or the Merger generally will be subject to information reporting and may be subject to “backup withholding.” See Section 3 — “Procedures for Tendering Shares — Backup Withholding” of this Offer to Purchase.

18

Table of Contents

Backup withholding generally applies if an Ikanos stockholder (i) fails to provide an accurate taxpayer identification number or (ii) in certain circumstances, fails to comply with applicable certification requirements. Certain penalties apply for failure to provide correct information and for failure to include reportable payments in income. In order to avoid backup withholding, a Ikanos stockholder generally must complete an IRS Form W-8IMY or an applicable IRS Form W-8BEN or W-8BEN-E (if the Ikanos stockholder is a Non-U.S. Holder) or the IRS Form W-9 that is included in the Letter of Transmittal (if the Ikanos stockholder is a U.S. Holder) in accordance with the instructions to the appropriate form.

Backup withholding is not an additional tax and may be refunded or credited against the Ikanos stockholder’s U.S. federal income tax liability, if any, provided that the Ikanos stockholder furnishes the required information to the IRS.

The Shares are listed and principally traded on the NASDAQ under the symbol “IKAN.” The Shares have been listed on NASDAQ since September 22, 2005.

The following table sets forth for the periods indicated the high and low sales prices per Share on the NASDAQ as reported in published financial sources. The prices reflect retroactively the 1:10 reverse stock split that occurred on February 13, 2015.

On August 5, 2015, the last full trading day before the public announcement of the execution of the Merger Agreement, the last reported sales price of Ikanos common stock reported on NASDAQ was $1.75 per Share. Therefore, the Offer Price of $2.75 per Share represents a premium of approximately 57.1% over the August 5, 2015 closing stock price, a 51.9% premium over the average trading price over the five trading days ending August 5, 2015 and a 38.8% premium over the average trading price over the 30 trading days ending August 5, 2015. Please obtain a recent quotation for your Shares prior to deciding whether or not to tender.

According to Ikanos’s publicly available documents, Ikanos has never paid a cash dividend on the Shares, and Ikanos is not permitted under the terms of the Merger Agreement to declare or pay a cash dividend prior to the closing of the Offer and the Merger (the “Closing”). If we acquire control of Ikanos, we currently intend that no dividends will be declared on the Shares prior to acquisition by us of the entire equity interest in Ikanos.

27

Table of Contents

Merger Consideration, and each holder of a certificate formerly representing any such Shares will cease to have any rights with respect thereto, except the right to receive the Merger Consideration in accordance with the Merger Agreement.

Payment for Shares

Prior to the Effective Time, Parent will designate a bank or trust company reasonably acceptable to Ikanos to act as agent (the “Depository Agent”) for the holders of Shares to receive the funds to which such holders will become entitled under the Merger Agreement and after the Effective Time to act as agent (the “Paying Agent”) for the holders of Shares to receive the funds to which such holders will become entitled under the Merger Agreement. Substantially concurrent with the Effective Time, Parent will deposit, or cause to be deposited, with the Depository Agent and Paying Agent cash sufficient to make payment of the aggregate consideration payable pursuant to the Merger Agreement (together, the “Payment Fund”). The Payment Fund will not be used for any other purpose. The Payment Fund will be invested by the Paying Agent as directed by the Surviving Corporation.

Promptly after the Effective Time (but in no event later than five business days thereafter), the Surviving Corporation will cause to be mailed to each person who was, at the Effective Time, a holder of record of Shares entitled to receive the Merger Consideration pursuant to (including in connection with an exercise or deemed exercise of an Ikanos Warrant) a form of letter of transmittal (which will be in customary form and will specify that delivery will be effected, and risk of loss and title to the certificates evidencing such Shares (the “Certificates”) will pass, only upon proper delivery of the Certificates (or effective affidavits of loss in lieu thereof) to the Paying Agent) and instructions for use in effecting the surrender of the Certificates or non-certificated Shares represented by book-entry (“Book-Entry Shares”) pursuant to such letter of transmittal. Upon surrender to the Paying Agent of Certificates (or effective affidavits of loss in lieu thereof) or Book-Entry Shares, together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions, the holder of such Certificates or Book-Entry Shares will be entitled to receive the Merger Consideration for each Share formerly evidenced by such Certificates or Book-Entry Shares, and such Certificates and Book-Entry Shares will then be canceled. No interest will accrue or be paid on the Offer Price payable upon the surrender of any Certificates or Book-Entry Shares for the benefit of the holder thereof. If the payment of any Merger Consideration is to be made to a person other than the person in whose name the surrendered Certificates formerly evidencing the Shares is registered on the stock transfer books of Ikanos, it will be a condition of payment that the Certificate so surrendered will be endorsed properly or otherwise be in proper form for transfer and that the person requesting such payment will have paid all transfer and other similar taxes required by reason of the payment of the Merger Consideration to a person other than the registered holder of the Certificate surrendered, or will have established to the satisfaction of the Surviving Corporation that such taxes either have been paid or are not applicable. None of Parent, Purchaser, and the Surviving Corporation will have any liability for the transfer and other similar taxes described in this paragraph under any circumstance. Payment of the applicable Merger Consideration with respect to Book-Entry Shares will only be made to the person in whose name such Book-Entry Shares are registered.

At any time following six months after the Effective Time, the Surviving Corporation will be entitled to require the Paying Agent to deliver to it any funds which had been made available to the Paying Agent and not disbursed to holders of Certificates or Book-Entry Shares (including, all interest and other income received by the Paying Agent in respect of all funds made available to it), and, thereafter, such holders will be entitled to look to the Surviving Corporation (subject to abandoned property, escheat and other similar laws) only as general creditors thereof with respect to the Merger Consideration that may be payable upon due surrender of the Certificates or Book-Entry Shares held by them. Notwithstanding the foregoing, neither the Surviving Corporation nor the Paying Agent will be liable to any holder of Certificates or Book-Entry Shares for the Merger Consideration delivered in respect of such share to a public official pursuant to any abandoned property, escheat or other similar laws. Any amounts remaining unclaimed by such holders at such time at which such amounts would otherwise escheat to, or become property of any governmental entity will become, to the extent

28

permitted by applicable laws, the property of the Surviving Corporation or its designee, free and clear of all claims or interest of any person previously entitled thereto.

At the close of business on the day of the Effective Time, the stock transfer books of Ikanos with respect to the Shares will be closed, and thereafter, there will be no further registration of transfers of Shares on the records of Ikanos. From and after the Effective Time, the holders of the Shares outstanding immediately prior to the Effective Time will cease to have any rights with respect to such shares except as otherwise provided herein or by applicable laws.

If any Certificate has been lost, stolen, or destroyed, upon the making of an effective affidavit of that fact by the person claiming such Certificate to be lost, stolen, or destroyed, which includes an agreement to indemnify and defend and hold harmless Parent, the Surviving Corporation, and the Paying Agent from and against any and all costs, claims, losses, judgments, damages, counsel fees, expenses, and liabilities whatsoever which each may suffer, sustain, or incur in connection with the failure of any statement, representation or warranty set forth in such affidavit, any payment for or transfer, exchange, or delivery of such Certificate and such person’s inability to locate such Certificate, and, if required by Parent or the Paying Agent, the posting by such person of a bond in customary amount as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will pay (less any amounts entitled to be deducted or withheld), in exchange for such lost, stolen, or destroyed Certificate, the applicable Merger Consideration to be paid in respect of the Shares formerly represented by such Certificate, as contemplated by the Merger Agreement.

Each of the Surviving Corporation, Parent, and Purchaser will be entitled to deduct and withhold (or cause the Paying Agent to deduct and withhold) from the consideration payable to any holder of the Shares, such cancelled in the money Ikanos Options, Ikanos RSUs, Ikanos SARs, Ikanos Warrants or any other amounts otherwise payable pursuant to the Merger Agreement. To the extent that amounts are so withheld and properly remitted, such withheld amounts will be treated for all as having been paid to the holder of the Shares, in the money Ikanos Options, Ikanos RSUs, Ikanos SARs, Ikanos Warrants, or other recipient of consideration in respect of which such deduction and withholding was made.

Stock Options

As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Ikanos Option that is then outstanding and unexercised, whether or not vested, will be cancelled. Further, with respect to those persons holding Time-based Ikanos Options with an exercise price less than the Merger Consideration (each, an “In-the-Money Option”), each such cancelled In-the-money Option will be converted into the right to receive (i) cash in an amount rounding down to the nearest whole cent, equal to the product obtained by multiplying (A) the total number of Shares subject to such Time-based Ikanos Option immediately prior to the Effective Time (without regard to vesting) and (B) the excess, if any, of (x) the Merger Consideration over (y) the exercise price payable per Share under such Time-based Ikanos Option, without interest. No holder of a cancelled Time-based Ikanos Option that has an exercise price per Share that is equal to or greater than the Merger Consideration will be entitled to any payment with respect to such cancelled Ikanos Option before or after the Effective Time. As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each unvested Performance-based Ikanos Option will be cancelled for no consideration.

SARs

As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Ikanos SAR that is then outstanding and unexercised, whether or not vested, will be cancelled. Further, with respect to those persons holding Ikanos SARs with an exercise price less than the Merger Consideration (each, an “In-the-money SAR”), each such cancelled In-the-money SAR will be converted into the right to receive (i) cash in an amount rounding down to the nearest whole cent, equal to the product obtained by multiplying (A) the total number of Shares subject to such Ikanos SAR immediately prior to the Effective Time (without regard to

29

Table of Contents

vesting) and (B) the excess, if any, of (x) the Merger Consideration over (y) the exercise price per Share under such Ikanos SAR, without interest. No holder of a cancelled Ikanos SAR that has an exercise price per Share that is equal to or greater than the Merger Consideration will be entitled to any payment with respect to such cancelled Ikanos SAR before or after the Effective Time.

RSUs

As of the Effective Time, by virtue of the Merger and without any action on the part of the holders thereof, each Ikanos RSU that is then outstanding and unexercised, whether or not vested, will be cancelled. Each such cancelled Ikanos RSU will be converted into the right to receive cash in an amount, rounding down to the nearest whole cent, equal to the product obtained by multiplying (i) the total number of Shares subject to such Ikanos RSU immediately prior to the Effective Time (without regard to vesting) and (ii) the Merger Consideration.

Payment of Stock Options, SARs, and RSUs

All amounts payable with respect to In-the-money Options, In-the-money SARs, and Ikanos RSUs will be paid through the Surviving Corporation’s or Purchaser’s payroll system in accordance with standard payroll practices, and subject to any required withholding for applicable taxes, unless the holder of an In-the-money Option, In-the-money SAR or Ikanos RSU is not a current or former employee of Ikanos or its subsidiaries for applicable tax purposes, in which case the consideration payable with respect to such In-the-money Options, In-the-money SARs or Ikanos RSUs will not be paid through payroll.

Warrants

Prior to September 17, 2015, Ikanos will satisfy all of its notification requirements under the terms of each outstanding and unexercised Ikanos Warrant. In addition, Ikanos will cause each such Ikanos Warrant to be automatically exercised in accordance with its respective terms and the numbers of Shares issuable by Ikanos in connection with such exercise, if any, will be cancelled and converted into the right to receive the Merger Consideration. Each of the Ikanos Warrants have a per share exercise price equal to the Offer Price. As a result, all outstanding Ikanos Warrants will be cancelled upon the consummation of the Merger and the holders of such Ikanos Warrants will not have any right to receive any consideration in respect thereof.

Preferred Stock

On the date of the closing of the Merger (the “Closing Date”), Ikanos will provide a notice of redemption to the holder of Series A Preferred Stock, par value $0.001 per share (the “Preferred Stock”), pursuant to the terms and conditions of the Certificate of Designation of Preferred Stock. From and after the notice of redemption having been duly given, and the redemption price of $1.00, as set forth in the Certificate of Designation, having been paid or irrevocably set aside for payment, the Preferred Stock will no longer be, or be deemed to be, outstanding for any purpose, and all rights preference and powers of the Preferred Stock will automatically cease and terminate, except the right of the holder of the Preferred Stock, upon surrender of the certificate for the Preferred Stock, to receive the redemption price of $1.00.

Loan Payoff

Prior to the Closing, Ikanos will satisfy all notification and consent requirements, as applicable, under the terms of the First Amended and Restated Loan and Security Agreement between Silicon Valley Bank and Ikanos, dated April 30, 2015 and the Loan and Security Agreement between Alcatel-Lucent USA, Inc. and Ikanos, dated September 29, 2014, as amended April 30, 2015 (together, the “Loans”). No less than five business days prior to the Closing Date, Ikanos will obtain payoff letters (each a “Payoff Letter”) for the Loans, each of which will (a) provide the dollar amount of all Loans required to be paid in order to fully and finally pay off such Loan as of the Closing (the “Payoff Amount”) and (b) indicate that Ikanos and its subsidiaries will be discharged from any

30

Subject to the terms and conditions of Merger Agreement, each of the parties will (i) promptly make all filings, notifications or obtain other consents required to be made or obtained by such party under antitrust laws in Taiwan and (ii) cooperate with each other in determining whether, and promptly preparing and making, any other filings or notifications or other consents required to be made with, or obtained from, any other governmental entities in transactions contemplated by the Merger Agreement.

Parent and Ikanos will have the right to review in advance, and to the extent practicable each will consult the other on, all the information relating to Parent or Ikanos, as the case may be, and any of their respective subsidiaries that appear in any filing made with, or written materials submitted to, any third party and/or any governmental entity in connection with the transactions contemplated by the Merger Agreement or filings to be made under applicable antitrust laws, and will consider comments reasonably proposed by Parent or Ikanos, as the case may be; provided, however, that with respect to any documents or materials required to be filed under applicable antitrust laws that contain information that is confidential or proprietary to the providing party, such information may be provided solely to those individuals acting as outside antitrust counsel for the other parties to the Merger Agreement; provided, further, that such counsel will not disclose such information to such other parties and will enter into a joint defense agreement in customary form with outside counsel for the providing party, if requested.

Without receiving Purchaser’s prior written consent, which Purchaser may withhold in its sole discretion, Ikanos will not (i) discuss with or commit to or agree with any governmental entity any action or agreement that would in any way limit Purchaser’s ability to receive the full benefits of the Merger Agreement, including but not limited to any agreement that would restrict Purchaser’s freedom of action with respect to the operation or ownership of Ikanos, or (ii) commit to or agree with any governmental entity to stay, toll or extend any applicable waiting period under applicable antitrust laws.

At or prior to the Effective Time, Ikanos may (through a nationally recognized insurance broker approved by Parent), and if Ikanos does not, the Surviving Corporation will purchase a six-year prepaid “tail” policy on terms and conditions with respect to coverage, deductibles and amounts no less favorable in the aggregate than the existing policy of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by Ikanos with respect to acts and omissions occurring prior to the Effective Time but in no event will the cost of such “tail” policy exceed an aggregate amount in excess of 250% of the annual premium currently payable by Ikanos with respect to such current policy, and if the total premiums payable for such insurance coverage exceeds such amount, Ikanos or the Surviving Corporation, as applicable, will obtain a policy with the greatest coverage available for a cost equal to such amount.

The Tender and Support Agreement provides that, no later than seven business days after the commencement of the Offer and the documents related to the Offer being made publicly available on the EDGAR database of the SEC, each Supporting Stockholder will tender into the Offer, and not withdraw, all outstanding Shares such Supporting Stockholder beneficially owns (within the meaning of Rule 13d-3 under the Exchange Act) as of the date of the Tender and Support Agreement or that such Supporting Stockholder acquires after such date unless the Tender and Support Agreement has been terminated. The Tender and Support Agreement will terminate upon termination of the Merger Agreement and certain other specified events. Upon the occurrence of the Ikanos Board changing their recommendation that the stockholders of Ikanos support the offer as a result of a permitted change in recommendation for an Intervening Event (not in connection with an alternative acquisition proposal), each Supporting Stockholder will be permitted to withdraw the excess of the aggregate number of Shares owned by the Supporting Stockholders as of the date of August 5, 2015 and any additional Shares acquired by the Supporting Stockholders after the entry into such agreement (the “Subject Securities”) that is equal to each Supporting Stockholder’s pro rata portion (as measured against the aggregate Subject Securities held by each of the Supporting Stockholders) of the sum of (i) 30% of the total number of Shares outstanding, on a fully diluted basis (the “30% Shares”) plus (ii) such additional number of Subject Securities (rounded down to the nearest whole Share) held by all of the Supporting Stockholders that is equal to product of (x) the total number of Subject Securities held by all Supporting Stockholders less the 30% Shares, multiplied by (y) the percentage, rounded to two decimal places, of the total number of outstanding Shares that have been tendered and not withdrawn prior to the expiration of the Offer by all holders of the Shares (other than the Supporting Stockholders).

For a complete understanding of the Confidentiality Agreement, you are encouraged to read the full text of the Confidentiality Agreement.

On February 23, 2015, QUALCOMM Incorporated and Ikanos entered into a confidentiality agreement (the “Confidentiality Agreement”) in connection with QUALCOMM Incorporated’s consideration of a possible transaction with or involving Ikanos. Under the Confidentiality Agreement, QUALCOMM Incorporated agreed, subject to certain exceptions, to keep confidential certain non-public information relating to Ikanos for a period of two years. The Confidentiality Agreement contains a non-solicitation provision prohibiting each party from, either directly or indirectly, soliciting for employment or otherwise contracting for the services of any employee of the other party for a period of 12 months from the date of the Confidentiality Agreement, subject to certain exceptions.

On June 22, 2015, Qualcomm Technologies, Inc., a wholly-owned subsidiary of QUALCOMM Incorporated and the parent company of Parent (“QTI”), and Ikanos entered into an Exclusivity Agreement (the “Exclusivity Agreement”). Under the terms of the Exclusivity Agreement, Ikanos agreed that, until the date that was the earliest to occur of (i) July 22, 2015 or (ii) the date that QTI advised Ikanos in writing that QTI was terminating discussions or negotiations relating to the transaction, Ikanos would not, directly or indirectly, take any action to solicit, initiate, seek, or knowingly encourage any inquiry, proposal, or offer from, furnish any information to, or participate in any discussions or negotiations with, any corporation, partnership, person or other entity or group (other than discussions with QTI) regarding certain alternative transactions. Ikanos agreed that any such negotiations in progress related to an alternative transaction would be terminated or suspended during such period. Ikanos agreed not to accept or enter into an agreement concerning any alternative transaction with any party other than QTI (or a direct or indirect subsidiary of QTI) prior to the expiration of such exclusivity period.

Purpose of the Offer

We are making the Offer pursuant to the Merger Agreement in order to acquire control of, and ultimately following the Merger, the entire equity interest in, Ikanos while allowing Ikanos’s stockholders an opportunity to receive the Offer Price promptly by tendering their Shares pursuant to the Offer. The Merger will be governed by Section 251(h) of the DGCL. Accordingly, Parent, we, and Ikanos have agreed to take all necessary and appropriate action to cause the Merger to become effective following the Offer Acceptance Time without a meeting of the stockholders of Ikanos in accordance with Section 251(h) of the DGCL, subject to the satisfaction or waiver of the remaining conditions set forth in the Merger Agreement.

Holders of Shares who tender their Shares pursuant to the Offer will cease to have any equity interest in Ikanos and will no longer participate in the possible future growth of Ikanos. If the Merger is consummated, the current holders of Shares will no longer have an equity interest in Ikanos and instead will only have the right to receive an amount in cash equal to the Offer Price or, to the extent that holders of Shares are entitled to and have properly demanded appraisal in connection with the Merger, the amounts to which such holders of Shares are entitled in accordance with Delaware law.

Plans for Ikanos

Except as otherwise disclosed in this Offer to Purchase, we do not have any present plans or proposals that would result in an extraordinary corporate transaction, such as a merger, reorganization, liquidation, or sale or transfer of a material amount of assets, involving Ikanos or any of its subsidiaries, any material changes in Ikanos’s present dividend policy, indebtedness, capitalization, or corporate structure. We will continue to evaluate and review Ikanos and its business, assets, corporate structure, capitalization, operations, properties, policies, management, and personnel with a view towards determining how to optimally realize any potential benefits which arise from the relationship of the operations of Ikanos with those of other business units of QUALCOMM Incorporated. Such evaluation and review is ongoing and is not expected to be completed until after the consummation of the Offer and the Merger. We intend to work with Ikanos’s management as part of a comprehensive review of Ikanos’s business, operations, capitalization, management, and personnel with a view to optimizing development of Ikanos’s potential.

Because the Merger will be governed by Section 251(h) of the DGCL, no stockholder vote will be required to consummate the Merger. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, Purchaser, Parent and Ikanos will consummate the Merger as soon as practicable. We do not expect there to be a significant period of time between the consummation of the Offer and the consummation of the Merger.

Possible Effects of the Offer on the Market for the Shares

If the Offer is consummated but the Merger does not take place, the number of stockholders and the number of Shares that are still in the hands of the public may be so small that there will no longer be an active or liquid public trading market (or possibly any public trading market) for Shares held by stockholders other than Purchaser. We cannot predict whether the reduction in the number of Shares that might otherwise trade publicly would have an adverse or beneficial effect on the market price for, or marketability of, the Shares or whether such reduction would cause future market prices to be greater or less than the Offer Price. If the Merger is consummated, stockholders not tendering their Shares in the Offer (other than those properly exercising their appraisal rights) will receive the same amount per Share as they would have received had they tendered their Shares in the Offer. Therefore, if the Merger takes place, the only difference between tendering and not tendering Shares in the Offer is that tendering stockholders will be paid earlier.

NASDAQ Listing

If the Shares remain listed on the NASDAQ when the Offer is completed, then depending upon the number of Shares purchased pursuant to the Offer, the Shares may not meet the standards for continued listing on the NASDAQ. If, as a result of the purchase of the Shares pursuant to the Offer, the Shares do not meet these criteria, the listing of Shares on the NASDAQ would be discontinued, and the market for the Shares could be adversely affected. In the event the Shares were no longer listed on the NASDAQ, price quotations for the Shares might still be available from other sources. The extent of the public market for the Shares and availability of such quotations would, however, depend upon such factors as the number of holders and/or the aggregate market value of the publicly held Shares at such time, the interest in maintaining a market in the Shares on the part of securities firms, the possible termination of registration of the Shares under the Exchange Act and other factors.

Registration under the Exchange Act

The Shares are currently registered under the Exchange Act. The purchase of the Shares pursuant to the Offer may result in the Shares becoming eligible for deregistration under the Exchange Act. Registration may be terminated upon application of Ikanos to the SEC if (i) the Shares are not listed on a national securities exchange, (ii) the Shares are not held by 300 or more holders of record and (iii) Ikanos is not otherwise required to furnish or file reports under the Exchange Act. Termination of the registration of the Shares under the Exchange Act, assuming there are no other securities of Ikanos subject to registration, would substantially reduce the information required to be furnished by Ikanos to holders of Shares and to the SEC and would make certain of the provisions of the Exchange Act, such as the short-swing profit recovery provisions of Section 16(b), the requirement to furnish a proxy statement pursuant to Section 14(a) in connection with a stockholder’s meeting and the related requirement to furnish an annual report to stockholders and the requirements of Rule 13e-3 under the Exchange Act with respect to “going private” transactions, no longer applicable to Ikanos. Furthermore, “affiliates” of Ikanos and persons holding “restricted securities” of Ikanos may be deprived of the ability to dispose of such securities pursuant to Rule 144 promulgated under the Securities Act of 1933, as amended. If registration of the Shares under the Exchange Act were terminated, the Shares would no longer be “margin securities” or eligible for listing or reporting on the NASDAQ. If the purchase of the Shares pursuant to the Offer results in the Shares becoming eligible for deregistration under the Exchange Act, it would be our intention to cause Ikanos to terminate registration of the Shares under the Exchange Act as soon after consummation of the Offer as the requirements for termination of registration of the Shares are met.

If registration of the Shares under the Exchange Act is not terminated prior to the Merger, then the registration of the Shares under the Exchange Act and the listing of the Shares on the NASDAQ will be terminated following the completion of the Merger.

Margin Regulations

The Shares are currently “margin securities” under the regulations of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”), which has the effect, among other matters, of allowing brokers to extend credit on the collateral of such Shares. Depending upon factors similar to those described above regarding listing and market quotations, following the purchase of Shares pursuant to the Offer the Shares might no longer constitute “margin securities” for the purposes of the Federal Reserve Board’s margin regulations and, therefore, could no longer be used as collateral for loans made by brokers.

As discussed in Section 11 — “The Transaction Documents — Summary of the Merger Agreement — Operating Covenants,” the Merger Agreement provides that from the date of the Merger Agreement until the Effective Time, Ikanos, without the prior consent of Parent will not declare, set aside for payment, or pay any dividend on, or make any other distribution in respect of, any of its capital stock.

The following is a summary of the conditions of the Offer set forth in the Merger Agreement and is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is filed as Exhibit (d)(1) to the Tender Offer Statement on Schedule TO filed with the SEC in connection with the Offer, and is incorporated herein by reference. Copies of the Merger Agreement and the Schedule TO and any other filings that we make with the SEC with respect to the Offer or the Merger may be obtained in the manner set forth in Section 8 — “Certain Information Concerning Purchaser and Parent.” Stockholders and other interested parties should read the Merger Agreement for a more complete description of the provisions summarized below.

This summary of the conditions to the Offer has been included in this Offer to Purchase to provide you with information regarding the terms of the Offer and is not intended to modify or supplement any factual disclosures about Ikanos, Purchaser or Parent (or any of their respective subsidiaries or affiliates) in public reports filed with the SEC. In particular, the Merger Agreement and this summary of conditions to the Offer are not intended to be, and should not be relied upon as, disclosures regarding any facts and circumstances relating to Ikanos, Purchaser or Parent (or any of their respective subsidiaries or affiliates).

The obligation of Purchaser to accept for payment and pay for Shares validly tendered (and not withdrawn) pursuant to the Offer is subject to the satisfaction of the conditions set forth in clauses “(a)” through “(j)” below. Notwithstanding any other provisions of the Offer, Purchaser will not be required to accept for payment or (subject to any applicable rules and regulations of the SEC, including Rule 14e-1(c) under the Exchange Act) pay for, and may delay the acceptance for payment of, or (subject to any such rules and regulations) the payment for, any tendered Shares, and may terminate the Offer: (i) upon termination of the Merger Agreement; and (ii) at any scheduled Expiration Date (subject to any extensions of the Offer) or amend the Offer, if (A) the Minimum Condition will not be satisfied by 12:01 a.m., Eastern Time on the Expiration Date of the Offer or (B) any of the additional conditions set forth in clauses “(b)” through “(h)” below will not be satisfied or waived in writing by Parent:

(a) there will have been validly tendered (not including any Shares tendered pursuant to guaranteed delivery procedures that were not actually delivered prior to the Expiration Date) and not validly withdrawn Shares that, considered together with all other Shares (if any) beneficially owned by Purchaser, represent one Share more than 50% of the sum of (x) the total number of Shares outstanding at the time of the expiration of the Offer and (y) the aggregate number of Shares issuable upon conversion, settlement or exercise of all then outstanding warrants, options, benefit plans, obligations or securities convertible or exchangeable into Shares or other rights to acquire or to be issued Shares (including all then outstanding Ikanos Options, Ikanos RSUs and Ikanos Warrants) from which Ikanos has received notices of conversion, settlement or exercise prior to the Expiration Date or which automatically convert, settle or exercise prior to the Acceptance Time (and as to which Shares have not yet been issued);

(c) Ikanos will have complied with or performed in all material respects all of the covenants and agreements in the Merger Agreement that Ikanos is required to comply with or perform at or prior to the Acceptance Time;

(d) since August 5, 2015, there will not have been any “Material Adverse Effect;”

(h) there will not be pending or threatened in writing any action commenced by any governmental entity against Parent, Purchaser or Ikanos or any of their respective affiliates in connection with the Offer, (i) that could lead to making illegal, restraining or prohibiting the consummation of any of the Transactions, (ii) that could lead

50

Table of Contents

to prohibiting or imposing limitations on the ability of Parent or Purchaser, or otherwise rendering Parent or Purchaser unable, to pay for or acquire any or all of the Shares pursuant to the Offer, or seeking to require divestiture of any or all of the Shares to be acquired pursuant to the Offer and the other transactions contemplated by the Merger Agreement, (iii) that could lead to prohibiting or imposing any limitations on the ownership or operation by Parent, Ikanos, or any of their affiliates of all or any portion of the businesses or assets of Parent, Ikanos, or any of their affiliates as a result of or in connection with the transactions contemplated by the Merger Agreement, or otherwise compelling Parent, Ikanos, or any of their affiliates to divest, hold separate, or enter into any license (whether pursuant to an exclusive or nonexclusive license) or similar agreement with respect to any portion of the business or assets of Parent, Ikanos, or any of their respective affiliates, (iv) that could lead to a requirement that Parent, Ikanos, or any of their affiliates enter into any voting trust arrangement, proxy arrangement or similar agreement or arrangement with respect to any portion of the business or assets of Parent, Ikanos, or any of their respective affiliates, or (v) that could lead to prohibiting or imposing limitations on the ability of Parent or Purchaser effectively to acquire, hold or exercise full rights of ownership of the Shares to be acquired pursuant to the transactions contemplated by the Merger Agreement, including the right to vote the Shares on all matters properly presented to the stockholders of Ikanos;

(j) this Agreement will not have been terminated in accordance with its terms.

Except for the Minimum Condition, each of the conditions above may be waived by Parent and Purchaser, in whole or in part at any time and from time to time, in the sole discretion of Parent and Purchaser. The failure by Parent or Purchaser at any time to exercise any of the foregoing rights will not be deemed a waiver of any such right and each such right will be deemed an ongoing right which may be asserted at any time and from time to time.

General

Except as described in this Section 16, based on a review of publicly available filings made by Ikanos with the SEC and other publicly available information concerning Ikanos and information supplied by Ikanos, we are not aware of any governmental license or regulatory permit that appears to be material to the business of Ikanos and its subsidiaries, taken as a whole, that might be adversely affected by our acquisition of the Shares (and the indirect acquisition of the stock of Ikanos’s subsidiaries) as contemplated in the Merger Agreement or of any approval or other action by any government or governmental administrative or regulatory authority or agency, domestic or foreign, that would be required for the acquisition or ownership of the Shares by us as contemplated in the Merger Agreement. Should any such approval or other action be required, we and Parent currently contemplate that, except as described below under “State Takeover Statutes,” such approval or other action will be sought. If certain types of adverse actions are taken with respect to the matters discussed below, we could, subject to the terms and conditions of the Merger Agreement, decline to accept for payment or pay for any Shares tendered. See Section 15 — “Conditions of the Offer” of this Offer to Purchase for a description of certain conditions to the Offer.

U.S. Antitrust Compliance

Based on the size of the proposed transaction, no filings will be required under the Hart-Scott-Rodino Act of 1976 (the “HSR Act”), and it is not subject to any waiting period under the HSR Act. However, at any time

51

Table of Contents

before or after consummation of the transaction, the Antitrust Division of the Department of Justice, the Federal Trade Commission or a state attorney general could take action with respect to the merger under applicable antitrust laws, including seeking to enjoin the consummation of the merger or seeking divestiture of assets of Parent or Ikanos. Private parties may also seek to take legal action under the antitrust laws under certain circumstances. There can be no assurance that a challenge to the merger on antitrust grounds will not be made or, if a challenge is made, of the results of such challenge.

Foreign Antitrust Compliance

Both Ikanos and Parent and their respective subsidiaries conduct business in many countries around the world. In connection with the acquisition of the Shares pursuant to the Offer, the laws of Taiwan require the filing of certain information with, and obtaining of the approval of the Taiwan Fair Trade Commission (“TFTC”) or expiration or termination of the relevant waiting period, before completion of the offer. The acquisition of Shares pursuant to the Offer may only be completed under Taiwanese law if the TFTC has made no objection to the proposed acquisition during the required 30-day waiting period (or an extended waiting period up to 90 days if the TFTC deems it necessary) which commences once the TFTC confirms that the notification from Purchaser pursuant to Article 11 of the Fair Trade Act of Taiwan is complete. We and Ikanos expect to submit the required notification to the TFTC shortly.

Further, if any action is taken before completion of the offer by any government or governmental authority, we may not be obligated to accept for payment or pay for any of the tendered Shares. See Section 15—“Conditions of the Offer” for certain conditions to the offer that could become applicable in the event of such an action.

Delaware Law

As a Delaware corporation, Ikanos is subject to Section 203 of the DGCL. In general, Section 203 of the DGCL would prevent an “interested stockholder” (generally defined in Section 203 of the DGCL as a person beneficially owning 15% or more of a corporation’s voting stock) from engaging in a “business combination” (as defined in Section 203 of the DGCL) with a Delaware corporation for three years following the time such person became an interested stockholder unless (i) before such person became an interested stockholder, the board of directors of the corporation approved the transaction in which the interested stockholder became an interested stockholder or approved the business combination, (ii) upon consummation of the transaction which resulted in the interested stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding for purposes of determining the number of shares of outstanding stock held by directors who are also officers and by employee stock plans that do not allow plan participants to determine confidentially whether to tender shares), or (iii) following the transaction in which such person became an interested stockholder, the business combination is (A) approved by the board of directors of the corporation and (B) authorized at a meeting of stockholders by the affirmative vote of the holders of at least 66 2/3% of the outstanding voting stock of the corporation not owned by the interested stockholder. In accordance with the provisions of Section 203, Ikanos Board has approved the Merger Agreement and the transactions contemplated thereby, and therefore the restrictions of Section 203 are inapplicable to the Merger and the transactions contemplated by the Merger Agreement.

State Takeover Statutes

A number of states have adopted laws which purport, to varying degrees, to apply to attempts to acquire corporations which have substantial assets, stockholders, principal executive offices or principal places of business or whose business operations otherwise have substantial economic effects in, such states. Ikanos, directly or through subsidiaries, conducts business in a number of states throughout the United States, some of which may have enacted such laws. Except as described herein, we do not know whether any of these laws will, by their terms, apply to the Offer or the Merger, and we have not complied with any such laws. To the extent that

52

Table of Contents

certain provisions of these laws purport to apply to the Offer or the Merger, we believe that there are reasonable bases for contesting the application of such laws.

In 1982, in Edgar v. MITE Corp., the Supreme Court of the United States invalidated on constitutional grounds the Illinois Business Takeover Statute which, as a matter of state securities law, made takeovers of corporations meeting certain requirements more difficult. However, in 1987, in CTS Corp. v. Dynamics Corp. of America, the Supreme Court held that the State of Indiana could, as a matter of corporate law, constitutionally disqualify a potential acquirer from voting shares of a target corporation without the prior approval of the remaining stockholders where, among other matters, the corporation is incorporated, and has a substantial number of stockholders, in the state. Subsequently, in TLX Acquisition Corp. v. Telex Corp., a U.S. federal district court in Oklahoma ruled that the Oklahoma statutes were unconstitutional as applied to corporations incorporated outside Oklahoma in that they would subject such corporations to inconsistent regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a U.S. federal district court in Tennessee ruled that four Tennessee takeover statutes were unconstitutional as applied to corporations incorporated outside Tennessee. This decision was affirmed by the United States Court of Appeals for the Sixth Circuit. In December 1988, a U.S. federal district court in Florida held in Grand Metropolitan PLC v. Butterworth that the provisions of the Florida Affiliated Transactions Act and the Florida Control Share Acquisition Act were unconstitutional as applied to corporations incorporated outside of Florida.

We are not aware of any other state takeover laws or regulations that are applicable to the Offer or the Merger and have not attempted to comply with any other state takeover laws or regulations. If any government official, Ikanos or third party seeks to apply any state takeover law (other than Section 203 of the DGCL) to the Offer or the Merger, we will take such action as then appears desirable, which action may include challenging the applicability or validity of such statute in appropriate court proceedings. If it is asserted that one or more state takeover statutes is applicable to the Offer or the Merger and an appropriate court does not determine that it is inapplicable or invalid as applied to the Offer or the Merger, we may be required to file certain information with, or to receive approvals from, the relevant state authorities or holders of Shares, and we may be unable to accept for payment or pay for Shares tendered pursuant to the Offer, or be delayed in continuing or consummating the Offer or the Merger. In such case, we may not be obligated to accept for payment or pay for any tendered Shares. See Section 15 — “Conditions of the Offer.”

Appraisal Rights

No appraisal rights are available to the holders of Shares in connection with the Offer. However, if the Merger is consummated, the holders of Shares immediately prior to the Effective Time who (i) did not tender their Shares in the Offer, (ii) follow the procedures set forth in Section 262 of the DGCL and (iii) do not thereafter withdraw their demand for appraisal of such Shares or otherwise lose their appraisal rights, in each case in accordance with the DGCL, will be entitled to have their Shares appraised by the Delaware Court of Chancery and receive payment of the “fair value” of such Shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with a fair rate of interest, as determined by such court.

The “fair value” of any Shares could be based upon considerations other than, or in addition to, the price paid in the Offer and the market value of such Shares. Holders of Shares should recognize that the value so determined could be higher or lower than, or the same as, the Offer Price or the consideration payable in the Merger (which is equivalent in amount to the Offer Price). Moreover, we may argue in an appraisal proceeding that, for purposes of such proceeding, the fair value of such Shares is less than such amount.

Under Section 262 of the DGCL, where a merger is approved under Section 251(h), either a constituent corporation before the effective date of the merger, or the surviving corporation within ten days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all

53

Table of Contents

shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of Section 262 of the DGCL. The Schedule 14D-9 constitutes the formal notice of appraisal rights under Section 262 of the DGCL.

As described more fully in the Schedule 14D-9, if a stockholder elects to exercise appraisal rights under Section 262 of the DGCL, such stockholder must do all of the following:

The foregoing summary of the appraisal rights of stockholders under the DGCL does not purport to be a complete statement of the procedures to be followed by stockholders desiring to exercise any appraisal rights available thereunder and is qualified in its entirety by reference to Section 262 of the DGCL. The proper exercise of appraisal rights requires strict and timely adherence to the applicable provisions of Delaware law. A copy of Section 262 of the DGCL is included as Annex II to the Schedule 14D-9.

The information provided above is for informational purposes only with respect to your alternatives if the Merger is consummated. If you tender your Shares into the Offer, you will not be entitled to exercise appraisal rights with respect to your Shares but, instead, subject to the conditions to the Offer, you will receive the Offer Price for your Shares.

Stockholder Approval Not Required

Section 251(h) of the DGCL provides that stockholder approval of a merger is not required if certain requirements are met, including, among others, that (i) the acquiring company consummates a tender offer for any and all of the outstanding common stock of the company to be acquired that, absent Section 251(h) of the DGCL, would be entitled to vote on the merger and (ii) following the consummation of such tender offer, the acquiring company owns at least such percentage of the stock of the company to be acquired that, absent Section 251(h) of the DGCL, would be required to adopt the merger. If the Minimum Condition is satisfied and we accept Shares for payment pursuant to the Offer, we will hold a sufficient number of Shares to ensure that Ikanos will not be required to submit the adoption of the Merger Agreement to a vote of the stockholders of Ikanos. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, we, Parent, and Ikanos will take all necessary and appropriate action to effect the Merger as promptly as practicable without a meeting of stockholders of Ikanos in accordance with Section 251(h) the DGCL.

We have retained D.F. King & Co., Inc. to act as the Information Agent and American Stock Transfer & Trust Company, LLC to act as the Depositary and Paying Agent in connection with the Offer. The Information Agent may contact holders of Shares by mail, telephone, telegraph and personal interviews and may request brokers, dealers, commercial banks, trust companies, and other nominees to forward materials relating to the Offer to beneficial owners. The Information Agent and the Depositary each will receive reasonable and customary compensation for their respective services, will be reimbursed for certain reasonable out-of-pocket expenses and will be indemnified against certain liabilities in connection therewith, including certain liabilities under the U.S. federal securities laws.
