Section 3 — Securities and Trading Markets

On September 16, 2011, GeoMet, Inc. (the “Company”) received a notification letter (the “Notice”) from The NASDAQ Stock Market (“NASDAQ”) advising the Company that for 30 consecutive trading days preceding the date of the Notice, the bid price of the Company’s common stock had closed below the $1.00 per share minimum required for continued listing on The NASDAQ Global Market pursuant to NASDAQ Marketplace Rule 5450(a)(1) (the “Minimum Bid Price Rule”).

The Notice has no effect on the listing of the Company’s common stock and preferred stock at this time and the Company’s common stock and preferred stock will continue to trade on the NASDAQ Global Market under the symbols “GMET” and “GMETP,” respectively.

The Notice also stated that the Company will be provided 180 calendar days, or until March 14, 2012, to regain compliance with the Minimum Bid Price Rule. To do so, the bid price of the Company’s common stock must close at or above $1.00 per share for a minimum of ten consecutive trading days prior to that date.

If compliance with the Minimum Bid Price Rule cannot be demonstrated by March 14, 2012, NASDAQ will provide written notification to the Company that the Company’s common stock is subject to delisting. The Company may, however, be eligible for an additional grace period if it satisfies the initial listing standards (with the exception of the Minimum Bid Price Rule) for listing on the NASDAQ Capital Market, and submits a timely notification to NASDAQ to transfer the listing of its common stock to the NASDAQ Capital Market. The Company may also appeal NASDAQ’s delisting determination to a NASDAQ Hearings Panel.

On September 20, 2011, the Company issued a press release announcing its receipt of the Notice. A copy of the press release is being furnished as Exhibit 99.1 to this report and is incorporated herein by reference.
