Gibraltar Announces Cash Tender Offer for its 8% Senior Subordinated Notes Due 2015

Buffalo, New York, January 15, 2013— Gibraltar Industries, Inc. (Nasdaq: ROCK), a leading manufacturer and distributor of products for building and industrial markets, has commenced a cash tender offer to purchase any and all of its $204 million in aggregate principal amount of outstanding 8% Senior Subordinated Notes due 2015 (CUSIP374689AC1) (the “Notes”). In conjunction with the tender offer, Gibraltar is soliciting consents from holders of the Notes to effect certain proposed amendments to the indenture governing the Notes. The tender offer and consent solicitation are being made on the terms and subject to the conditions set forth in the Offer to Purchase and Consent Solicitation Statement (the “Offer to Purchase”) and related Letter of Transmittal and Consent, each dated January 16, 2013.

The tender offer and consent solicitation are subject to the satisfaction or waiver of certain conditions, as described in the Offer to Purchase, including the condition that Gibraltar shall have received net proceeds from one or more financings sufficient to repurchase all of the Notes tendered, including the payment of all premiums, if any, consent payments, accrued interest, and costs and expenses incurred in connection with the tender offer and consent solicitation, as described in more detail in the Offer to Purchase.

Gibraltar is offering to purchase the Notes at a price of $1,007.08 for each $1,000 in principal amount of Notes (the “Tender Offer Consideration”) validly tendered (and not validly withdrawn) and accepted for purchase pursuant to the tender offer, plus accrued interest. Holders who validly tender (and do not validly withdraw) their Notes and validly deliver (and do not validly revoke) their consents to the proposed amendments at or prior to 5:00 p.m., New York City time, on January 30, 2013, unless extended or earlier terminated (such date and time, as the same may be extended or earlier terminated, the “Consent Deadline”) will also receive a consent payment of $10.00 for each $1,000 in principal amount of Notes validly tendered (and not validly withdrawn) and accepted for purchase pursuant to the tender offer. The total consideration for each $1,000 principal amount of Notes validly tendered and not validly withdrawn and accepted for purchase at or prior to the Consent Deadline will be an amount equal to $1,017.08 (the “Total Consideration”). Holders that tender their Notes in the tender offer will be deemed to have consented to the proposed amendments to the indenture governing the Notes if such tender is delivered by the Consent Deadline. Gibraltar will not pay the consent payment to holders who tender Notes and deliver consents to the proposed amendments after the Consent Deadline.

The proposed amendments to the indenture governing the Notes would eliminate substantially all of the restrictive covenants, certain affirmative covenants, certain events of default and certain conditions to legal defeasance or covenant defeasance contained in the indenture and the Notes. Holders may not deliver consents to the proposed amendments without validly tendering the related Notes in the tender offer and may not revoke their consents without withdrawing the previously tendered Notes to which they relate.

Notes validly tendered at or prior to 5:00 p.m., New York City time, on January 30, 2013 (the “Withdrawal Date”) may be validly withdrawn and the related consents may be validly revoked at any time prior to the Withdrawal Date. Tendered notes and delivered consents may not be validly withdrawn or revoked after the Withdrawal Date, except under certain limited circumstances as described in the Offer to Purchase.

The Offer to Purchase contains early settlement provisions, whereby Notes validly tendered (and not validly withdrawn) on or prior to the business day prior to the early acceptance date (which early acceptance date is expected to be January 31, 2013) may be accepted. Payment of the applicable consideration for such notes is expected to be made on or promptly following such acceptance.

The tender offer will expire at 11:59 p.m., New York City time, on February 13, 2013 unless extended or earlier terminated by Gibraltar (such date and time, as the same may be extended or earlier terminated, the “Expiration Time”).

If the consents representing the majority of the aggregate principal amount of the outstanding Notes (the “Majority Consent”) are received but not all Notes are validly tendered pursuant to the tender offer, Gibraltar currently intends, but is not obligated, to redeem or satisfy and discharge any untendered Notes in accordance with the indenture governing the Notes. If the Majority Consent is not received, Gibraltar reserves the right to redeem any untendered Notes in accordance with the indenture governing the Notes and/or satisfy and discharge the indenture governing the Notes.
