CLEVELAND, OH – April 4, 2016 – Aleris International, Inc. (the “Company”), a wholly owned subsidiary of Aleris Corporation (“Aleris”), today announced that holders of approximately $273,162,000 aggregate principal amount (representing approximately 62.8%) of the Company’s 7 ⁵⁄₈% Senior Notes due 2018 (CUSIP No. 014477 AM5) (the “Notes”) validly tendered (and did not validly withdraw) their Notes prior to 5:00 p.m., New York City time, on April 1, 2016 (the “Early Tender Deadline”) pursuant to the Company’s previously announced cash tender offer (the “Tender Offer”) for any and all of its outstanding Notes.

The table below reflects certain terms of the Tender Offer:

CUSIP Number	Title of Security	Aggregate Principal Amount Outstanding1		Late Tender Offer Consideration2, 3		Early Tender Premium2		Total Tender Offer Consideration2, 3
014477 AM5	7 5⁄8% Senior Notes due 2018	$	434,933,000	$	991.25	$	30.00	$	1,021.25

(1) Amount outstanding as of March 21, 2016, the date the Tender Offer commenced.

(2) Per $1,000 principal amount of Notes accepted for purchase.

(3) Excludes accrued and unpaid interest, which will be paid in addition to the Late Tender Offer Consideration or Total Tender Offer Consideration, as applicable.

The Company has elected to exercise the Early Settlement Election described in the Offer to Purchase, dated March 21, 2016, relating to the Tender Offer. Holders of Notes who validly tendered (and did not validly withdraw) their Notes on or prior to the Early Tender Deadline received the Total Tender Offer Consideration for the Notes tendered on April 4, 2016 (the “Early Settlement Date”) and accrued and unpaid interest on the Notes up to the Early Settlement Date.

Continuing Tender Offer

Holders who validly tender their Notes after the Early Tender Deadline and on or before the Expiration Date (as defined below) will be eligible to receive only the Late Tender Offer Consideration, which is equal to the Total Tender Offer Consideration minus the Early Tender Premium, plus accrued and unpaid interest on the Notes up to the Final Settlement Date (as defined below). The Tender Offer will expire at 12:00 midnight, New York City time, at the end of the day on April 15, 2016, unless extended (such date and time, as the same may be extended in the Company’s sole discretion, the “Expiration Date”). The Company currently expects the Tender Offer to be settled on April 18, 2016 (the “Final Settlement Date”). The time and date on or before which validly tendered Notes may be validly withdrawn expired at 5:00 p.m., New York City time, on April 1, 2016. Holders may not validly withdraw any validly tendered Notes after that time and date, except in limited circumstances where the Company determines additional rights are required by law.

The Company’s obligation to accept any Notes that are validly tendered and to pay the Late Tender Offer Consideration are set forth solely in the Offer to Purchase and the related Letter of Transmittal. This press release is neither an offer to purchase nor a solicitation of an offer to sell any Notes. The Tender Offer is being made only by, and pursuant to the terms of, the Offer to Purchase and the related Letter of Transmittal, and the information in this press release is qualified by reference to the Offer to Purchase and the related Letter of Transmittal. Subject to applicable law, the Company may, in its sole discretion, amend, extend or, subject to certain conditions, terminate the Tender Offer.

Credit Suisse Securities (USA) LLC is the Dealer Manager for the Tender Offer. Persons with questions regarding the Tender Offer should contact Credit Suisse Securities (USA) LLC at (212) 538-2147 (collect) or (800) 820-1653 (toll-free) (Attention: Liability Management Group).

Redemption of 2018 Notes

Concurrently with the commencement of the Tender Offer, the Company directed that U.S. Bank National Association, as trustee under the indenture governing the Notes (as supplemented to date, the “Indenture”), give notice of the Company’s intent in accordance with the Indenture, to redeem on April 20, 2016 (such date, including as it may be delayed, the “Redemption Date”) in full the aggregate principal amount of the Notes that remain outstanding after the Expiration Date of the Tender Offer and the Company’s acceptance for payment of, and payment for, Notes that were validly tendered and not validly withdrawn in the Tender Offer, at a redemption price of 101.906% (the “Redemption Price”) of the outstanding aggregate principal amount of the Notes to be redeemed, plus accrued and unpaid interest to the Redemption Date.

The redemption of the Notes and the payment of the Redemption Price, plus accrued and unpaid interest to the Redemption Date, on the Redemption Date were conditioned upon the Company having completed a debt financing on terms and conditions satisfactory to the Company yielding sufficient net cash proceeds, together with up to $12.0 million of cash on hand, to fund the maximum consideration payable for the valid tender of all currently outstanding Notes, plus accrued interest, pursuant to the Tender Offer, after giving effect to the

payment of all discounts, fees and expenses incurred in connection with the debt financing and the Tender Offer (collectively, the “Redemption Condition”). On April 4, 2016, the Company completed the issuance of $550.0 million aggregate principal amount of 9.50% Senior Secured Notes due 2021 and accordingly the Redemption Condition has been satisfied. This press release does not constitute an offer to purchase the Notes or a notice of redemption thereof.
