II. CLAIMANT IDENTIFICATION

You are a Member of the Settlement Class if you purchased or otherwise acquired: (i) Arconic securities between November 4, 2013 and June 27, 2017, both dates inclusive, including for the avoidance of doubt any Arconic Depositary Shares; and (ii) Arconic Depositary Shares, each representing a 1/10th interest in a share of 5.375% Class B Mandatory Convertible Preferred Stock, Series 1, par value $1 per share, liquidation preference $500 per share pursuant to and/or traceable to the Registration Statement and Prospectus issued in connection with Arconic’s September 18, 2014 initial public preferred stock offering.

Excluded from the Settlement Class are: (i) the Defendants; (ii) the current and Settlement Class Period officers and directors of Arconic and the Underwriter Defendants; (iii) the Immediate Family Members of the Individual Defendants; and (iv) the legal representatives, affiliates, heirs, successors-in-interest or assigns of any such excluded party and any entity in which such excluded parties have or had a controlling interest, provided, however, that any Investment Vehicle shall not be excluded from the Settlement Class. Also excluded from the Settlement Class is any Person who would otherwise be a Member of the Settlement Class but who validly and timely requests exclusion in accordance with the requirements set by the Court in connection with the Settlement.

Upon entry into the Online Filing Site, use the first section entitled “Claimant Identification” to identify each purchaser or acquirer of record (“nominee”), if different from the beneficial purchaser or acquirer of the Arconic Securities that forms the basis of this claim. THIS CLAIM MUST BE FILED BY THE ACTUAL BENEFICIAL PURCHASER(S) OR ACQUIRER(S) OR THE LEGAL REPRESENTATIVE OF SUCH PURCHASER(S) OR ACQUIRER(S) OF THE ARCONIC SECURITIES UPON WHICH THIS CLAIM IS BASED.

All joint purchasers or acquirers must sign this Claim Form. Executors, administrators, representatives, guardians, agents, conservators, and trustees must complete and sign this Claim Form on behalf of Persons represented by them and evidence of their authority must accompany this Claim Form and their titles or capacities must be stated. The last four digits of the Social Security Number (or full Taxpayer Identification Number) and telephone number of the beneficial owner may be used in verifying the claim. Failure to provide the foregoing information could delay verification of your claim or result in rejection of the claim.

If you are acting in a representative capacity on behalf of a Member of the Settlement Class (for example, as an executor, administrator, agent, trustee, or other representative), you must submit evidence of your current authority to act on behalf of that Member of the Settlement Class. Such evidence would include, for example, letters testamentary, letters of administration, or a copy of the trust documents.

One claim should be submitted for each separate legal entity. Separate Claim Forms should be submitted for each separate legal entity (e.g., a claim from joint owners should not include separate transactions of just one of the joint owners, and an individual should not combine his or her IRA transactions with transactions made solely in the individual’s name). Conversely, a single Claim Form should be submitted on behalf of one legal entity including all transactions made by that entity on one Claim Form, no matter how many separate accounts that entity has (e.g., a corporation with multiple brokerage accounts should include all transactions made in all accounts on one Claim Form).

NOTICE REGARDING INSTITUTIONAL ELECTRONIC FILES: Certain claimants with large numbers of transactions may request to, or may be requested to, submit information regarding their transactions in electronic files. All claimants MUST submit a manually signed paper Proof of Claim listing all their transactions whether or not they also submit electronic copies. If you wish to file your claim electronically, you must contact the Claims Administrator via email at info@ArconicSecuritiesSettlement.com or toll-free at 866-963-9979 to obtain the required file layout. No electronic files will be considered to have been properly submitted unless the Claims Administrator issues to the claimant a written acknowledgement of receipt and acceptance of electronically submitted data.

III. CLAIM FORM

Use the second section in the Online Filing Site entitled “Schedule of Transactions in Arconic Securities” to supply all required details of your transaction(s) in Arconic Securities. If you need more space or additional schedules, attach separate sheets giving all of the required information in substantially the same form. Sign and print or type your name on each additional sheet.

Please note that only the Arconic Securities purchased or otherwise acquired during the Settlement Class Period (i.e., between November 4, 2013 and June 27, 2017, both dates inclusive) are eligible under the Plan of Allocation to potentially share in the proceeds of the Settlement. However, under the “90-Day Lookback Period” (described in the Plan of Allocation set forth in the Notice), your sales of Arconic Securities during the period from June 27, 2017 through and including the close of trading on September 22, 2017, will be used for purposes of calculating Recognized Loss amounts under the Plan of Allocation. Therefore, in order for the Claims Administrator to be able to balance your claim, the requested transaction information during the 90 Day Lookback Period must also be provided. Furthermore, in order to calculate the Recognized Loss amount for the Preferred Stock for claims under the Securities Act, requested transaction information during the period from June 27, 2017, through and including the close of trading on September 29, 2017, must also be provided. Failure to report all transaction and holding information during the requested time period may result in the rejection of your claim.

List these transactions separately and in chronological order, by trade date, beginning with the earliest. You must accurately provide the month, day, and year of each transaction you list.

For purpose of the Plan of Allocation, for short-sale transactions, the date of covering a “short sale” is deemed to be the date of purchase of Arconic Securities, and the date of a “short sale” is deemed to be the date of sale of Arconic Securities.

For each transaction, you must provide, together with this Claim Form, copies of stockbroker confirmation slips, stockbroker statements, or other documents adequately evidencing your transactions in Arconic Securities. If any such documents are not in your possession, please obtain a copy or equivalent documents from your broker because these documents are necessary to prove and process your claim. Failure to provide this documentation could delay verification of your claim or result in rejection of your claim.

PLEASE NOTE As set forth in the Plan of Allocation, each Authorized Claimant shall receive his, her, their, or its pro rata share of the Net Settlement Fund. If the prorated payment to any Authorized Claimant calculates to less than $10.00, it will not be included in the calculation and no distribution will be made to that Authorized Claimant.
