CEO Harry Vafias commented

For the three months ended June 30, 2011 we reported record revenue figure for the second quarter in a row. We continue to generate positive income from operations and aside from the effect of vessel sales, our operations  are improving compared to last year, as the LPG market has strengthened. As of the date of this press release, we have successfully concluded the sale of four older LPG carriers and have taken delivery of two newbuilding LPG carriers. With the scheduled addition of three more newbuilding LPG carriers over the next year our leading position in the LPG handysize segment will strengthen and we will possess a younger and operationally more efficient fleet. Our healthy balance sheet and our improved cash position allow us to be optimistic for the future. We have increased the period coverage for our fleet to 75% for the remainder of 2011 and almost 50% for 2012, thus securing to a large extent our revenue stream. I am also pleased to announce that under our Share Repurchase Plan that was adopted in 2010 during the current month we made purchases of approximately 350,000 shares. Since the adoption of the plan we have repurchased approximately 1.6 million shares.

Forward-Looking Statements

Matters discussed in this release may constitute forward-looking statements. Forward-looking statements reflect our current views with respect to future events and financial performance and may include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are other than statements of historical facts. The forward-looking statements in this release are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management's examination of historical operating trends, data contained in our records and other data available from third parties. Although STEALTHGAS INC. believes that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies which are difficult or impossible to predict and are beyond our control, STEALTHGAS INC. cannot assure you that it will achieve or accomplish these expectations, beliefs or projections. Important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include the strength of world economies and currencies, general market conditions, including changes in charter hire rates and vessel values, charter counterparty performance, changes in demand that may affect attitudes of time charterers to scheduled and unscheduled dry dockings, changes in STEALTHGAS INC's operating expenses, including bunker prices, dry-docking and insurance costs, ability to obtain financing and comply with covenants in our financing arrangements, or actions taken by regulatory authorities, potential liability from pending or future litigation, domestic and international political conditions, potential disruption of shipping routes due to accidents and political events or acts by terrorists.

1) Average number of vessels is the number of vessels that constituted our fleet for the relevant period, as measured by the sum of the number of days each vessel was a part of our fleet during the period divided by the number of calendar days in that period.

2) Total calendar days are the total days the vessels were in our possession for the relevant period including off-hire days associated with major repairs, drydockings or special or intermediate surveys.

3) Total voyage days for fleet reflect the total days the vessels were in our possession for the relevant period net of off-hire days associated with major repairs, drydockings or special or intermediate surveys.

4) Fleet utilization is the percentage of time that our vessels were available for revenue generating voyage days, and is determined by dividing voyage days by fleet calendar days for the relevant period.

5) Total time charter days for fleet are the number of voyage days the vessels in our fleet operated on time charters for the relevant period.

6) Total spot market charter days for fleet are the number of voyage days the vessels in our fleet operated on spot market charters for the relevant period.

7) Fleet operational utilization is the percentage of time that our vessels generated revenue, and is determined by dividing voyage days (excluding commercially idle days) by fleet calendar days for the relevant period.

8) Time charter equivalent, or TCE, is a measure of the average daily revenue performance of a vessel on a per voyage basis. Our method of calculating TCE is consistent with industry standards and is determined by dividing voyage revenues (net of voyage expenses) by voyage days for the relevant time period. Voyage expenses primarily consist of port, canal and fuel costs that are unique to a particular voyage, which would otherwise be paid by the charterer under a time charter contract, as well as commissions. TCE is a standard shipping industry performance measure used primarily to compare period-to-period changes in a shipping company's performance despite changes in the mix of charter types (i.e., spot charters, time charters and bareboat charters) under which the vessels may be employed between the periods.

9) Vessel operating expenses, which include crew costs, provisions, deck and engine stores, lubricating oil, insurance, maintenance and repairs, is calculated by dividing vessel operating expenses by fleet calendar days for the relevant time period.

10) Total operating expenses, or TOE, is a measurement of our total expenses associated with operating our vessels. TOE is the sum of vessel operating expenses and general and administrative expenses. Daily TOE is calculated by dividing TOE by fleet calendar days for the relevant time period.

Reconciliation of EBITDA, Adjusted Net Income and Adjusted earnings per share:

EBITDA represents net earnings before interest, taxes, depreciation and amortization. EBITDA, Adjusted net Income and adjusted earnings per share are not items recognised by the United States generally accepted accounting principles and should not be considered as an alternative to net income or cash flow from operations or any other measure required by USGAAP. Our calculation of EBITDA and Adjusted net income may not be comparable to that reported by other companies in the shipping or other industries.

EBITDA, Adjusted net income and Adjusted earnings per share are included herein because they are a basis upon which we assess our financial performance, assist in comparability of our performance from period to period and provide additional information on fleet operational results. We also use EBITDA to assess our liquidity position and believe it presents useful information to investors regarding a company's ability to service and/or incur indebtedness.
