CAPITAL PRODUCT PARTNERS L.P. ANNOUNCES THIRD QUARTER 2012 FINANCIAL RESULTS AND CHARTER RENEWALS FOR A NUMBER OF ITS VESSELS

ATHENS, Greece, October 31, 2012 — Capital Product Partners L.P. (the “Partnership”) (NASDAQ: CPLP), an international owner of modern double-hull tankers, today released its financial results for the third quarter ended September 30, 2012.

The Partnership’s net income for the quarter ended September 30, 2012, was $7.2 million. After taking into account the $3.3 million preferred interest in net income attributable to the unit holders of 15,555,554 Class B Convertible Preferred Units (the “Class B Units” and the “Class B Unitholders”), which were issued during the second quarter of 2012, the result was $0.06 net income per limited partnership unit, which is $0.07 higher than the $0.01 loss per unit from the previous quarter ended June 30, 2012, and $1.44 lower than the $1.50 net income per unit in the third quarter of 2011. Prior to taking into account the preferred interest in income attributable to the Class B Unitholders, the result per limited partnership unit for the quarter ended September 30, 2012, was net income of $0.10. The Partnership’s reported net income for the third quarter of 2011 included a $65.9 million gain from bargain purchase related to the excess of the fair value of the Crude Carriers Corp. (“Crude Carriers”) net assets acquired over their purchase price under the terms of the merger agreement between Crude Carriers and the Partnership completed on September 30, 2011.

Operating surplus for the quarter ended September 30, 2012, was $21.9 million, which is $5.0 million higher than the $16.9 million from the second quarter of 2012, and $11.6 million higher than the $10.3 million from the third quarter of 2011. The operating surplus adjusted for the payment of distributions to the Class B Unitholders was $18.6 million for the third quarter ended September 30, 2012. Operating surplus is a non-GAAP financial measure used by certain investors to measure the financial performance of the Partnership and other master limited partnerships. Please refer to the section “Appendix A” at the end of the press release, for a reconciliation of this non-GAAP measure to net income.

Revenues for the third quarter of 2012 were $38.0 million, compared to $30.9 million in the third quarter of 2011. The Partnership’s revenues mainly reflect the increased fleet size following the acquisition of Crude Carriers on September 30, 2011, and include $1.0 million in profit sharing revenues earned by the M/T Achilleas, as the crude tanker spot rates that our charterers earned on this vessel were at levels higher than the base rate it is fixed at. The profit sharing arrangements in the charters of a number of our crude vessels allow us to share the excess over the base rate on a 50/50 basis with our charterers, and are settled biannually.

Total expenses for the third quarter of 2012 were $26.9 million compared to $21.4 million in the third quarter of 2011, primarily due to the higher operating expenses incurred as a result of the higher number of vessels in our fleet following the acquisition of Crude Carriers. The vessel operating expenses for the third quarter of 2012 amounted to $11.3 million, including a $5.5 million charge by a subsidiary of our Sponsor, Capital Maritime & Trading Corp. (“Capital Maritime” or “CMTC”), for the commercial and technical management of our fleet under the terms of our management agreements, compared to $8.6 million in the third quarter of 2011. The total expenses for the third quarter of 2012 also include $12.0 million in depreciation, compared to $8.6 million in the third quarter of 2011. General and administrative expenses for the third quarter of 2012 amounted to $2.4 million, which includes a $1.1 million non-cash charge related to the Partnership’s Omnibus Incentive Compensation Plans.

Total other expense, net for the third quarter of 2012 amounted to $3.8 million compared to $6.8 million for the third quarter of 2011. The decrease in the interest expense and finance cost for the third quarter of 2012 reflects the termination of certain interest rate swaps and the reduction of the Partnership’s total debt, when compared to the third quarter of 2011.

As of September 30, 2012, the Partners’ capital stood at $627.4 million, which is $110.1 million higher than the Partners’ capital as of December 31, 2011. This increase reflects the issuance of the 15,555,554 Class B Units, which raised gross proceeds of approximately $140.0 million.

As of September 30, 2012, the Partnership’s total debt had decreased by $170.1 million to $463.5 million, compared to total debt of $633.6 million as of December 31, 2011. In connection with the issuance of the Class B Units, the Partnership executed amendments to its three credit facilities and prepaid debt of $149.6 million, also utilizing part of its cash balances. The amendments provide for a deferral of all remaining scheduled amortization payments that were due between 2012 and 2015 (inclusive) under each of the Partnership’s credit facilities until March 31, 2016. As of September 30, 2012, the Partnership had swapped $59.1 million of its debt into fixed rates, whereas the remaining $404.4 million of its total debt of $463.5 million is in floating rates.

Fleet Developments

The M/T Miltiadis M II (162,397dwt, Ice 1A Crude/Product Carrier, built 2006 Daewoo Shipbuilding & Marine Engineering Co Ltd) has been chartered through Subtec S.A. de C.V. of Mexico to Petróleos Mexicanos (“PEMEX”), the state-owned Mexican petroleum company, under a charter expected to expire in September 2014 at a higher rate than the gross rate of $18,250 earned by the vessel under its previous employment with CMTC. In view of this employment opportunity, our sponsor, CMTC, following the unanimous approval of the Conflicts Committee, has agreed to terminate its employment of the vessel which was expected to expire in April 2013.

The M/T Apostolos (47,782dwt, Ice 1A IMO II/III, built 2007 Hyundai Mipo Dockyard Co Ltd) secured employment for 12 (+/- 30 days) months with CMTC at a gross rate of $14,000 per day with earliest expected redelivery in August 2013.

The M/T Akeraios (47,781dwt, Ice 1A IMO II/III, built 2007 Hyundai Mipo Dockyard Co Ltd) has extended its employment to CMTC for an additional 12 months (+/- 30 days) at a gross rate of $14,000 per day with earliest expected redelivery in June 2013.

The M/T Agisilaos (36,760dwt, Ice 1A IMO II/III, built 2006 Hyundai Mipo Dockyard Co Ltd) has extended its employment to CMTC for an additional 12 months (+/- 30 days) at a gross rate of $13,500 per day with earliest expected redelivery in June 2013.

The M/T Alkiviadis (36,721dwt, Ice 1A IMO II/III, built 2006 Hyundai Mipo Dockyard Co Ltd) has extended its employment to CMTC for an additional 12 months (+/- 30 days) at an increased gross rate of $13,417 per day with earliest expected redelivery in June 2013.

The charters of each of the M/T Apostolos, M/T Akeraios, M/T Agisilaos and M/T Alkiviadis are subject to 50/50 profit sharing arrangements for breaching Institute Warranty Limits and were unanimously approved by the Conflicts Committee of the Partnership.

As a result of the above employment agreements, the Partnership’s charter coverage for the remainder of 2012 and 2013 now stand at 96% and 75%, respectively.

On October 19, 2012, Overseas Shipholding Group Inc (“OSG”) issued a statement that it was in negotiations with its bank creditors and that it was evaluating its strategic options, including the potential voluntary filing of a petition for relief under Chapter 11 of the U.S. Bankruptcy Code. The Partnership has three IMO II/III Chemical/Product tankers (M/T Alexandros II, M/T Aristotelis II and M/T Aris II) on

long term bareboat charter to subsidiaries of OSG. These charters are scheduled to terminate in February, July and September of 2018, respectively, and are at rates that are substantially above current market rates. In the event OSG files for relief under the U.S. Bankruptcy Code or otherwise restructures its affairs, it may seek to terminate or seek to restructure or modify its charter arrangements for the three IMO II/III Chemical/Product tankers and, depending on various factors, including prevailing market conditions, such actions could have an adverse effect on our future revenues from the three vessels.

Market Commentary

Overall, product tanker average spot earnings for the third quarter of 2012 remained soft, as sluggish economic growth in the US, weak demand in Europe and few arbitrage opportunities failed to support a higher spot rate environment. The month of September saw a more active transatlantic market as increased demand from West Africa coincided with the opening up of the gasoline arbitrage between the US and Europe.

The product tanker period charter market remained active albeit with fewer fixtures and at lower levels compared to the first half of 2012 due to the softer rates prevailing in the spot market.

On the supply side, the product tanker order book continued to experience substantial slippage during 2012, as approximately 45% of the expected MR and handy size tanker newbuildings were not delivered on schedule. Analysts expect that net fleet growth for MR and handy size product tankers for 2012 will be in the region of 3.1%, while overall demand for product tankers for the year has been revised downwards to 2.8% as European and US demand for seaborne oil products continues to decline. We believe the current low product tanker order book is amongst the lowest in the shipping industry and given the demand fundamentals and the order book slippage, it should positively affect spot and period charter rates going forward.

The crude tanker spot market dropped sharply in July and remained at depressed levels for most of the remaining summer months as a result of a number of factors including low fixture activity due to seasonal weakness, the build-up of commercial crude inventories that occurred during the first half of the year, the shutdown of the Motiva refinery in the US Gulf as well as high bunker prices and increased tonnage supply.

Slippage for the crude tanker order book as of the end of September 2012 continued to affect tonnage supply as approximately 26% of the expected crude newbuildings were not delivered on schedule.

Industry analysts expect the crude tanker order book slippage and cancellations to increase going forward due to the historically weak spot market, the soft shipping finance environment and downward pressure on asset values. Crude tanker deadweight demand is expected to grow by 2.6% in the full year 2012.

Quarterly Common and Class B Unit Cash Distribution

On October 23, 2012, the Board of Directors of the Partnership declared a cash distribution of $0.2325 per common unit for the third quarter of 2012, in line with management’s annual guidance. The third quarter common unit cash distribution will be paid on November 15 , 2012, to unit holders of record on November 8 , 2012.

In addition, on October 23, 2012, the Board of Directors of the Partnership declared a cash distribution of $0.21375 per Class B Unit for the third quarter of 2012, in line with the Partnership’s Second Amended and Restated Partnership Agreement, as amended. The third quarter Class B Unit cash distribution will be paid on November 9 , 2012, to Class B Unitholders of record on November 2 , 2012.

Management Commentary

Mr. Ioannis Lazaridis, Chief Executive and Chief Financial Officer of the Partnership’s General Partner, commented:

“Having completed a very important transaction for the Partnership during the second quarter of 2012 with the issuance of the Class B Units, we are very pleased to have secured employment during the third quarter for five of our vessels at favorable day rates enhancing further our charter coverage for this year and next. We have extended our relationship with PEMEX with the employment of the M/T Miltiadis M II, and our Sponsor continues to provide medium term employment to our product tankers allowing us to potentially capitalize on a market recovery looking ahead. We are pleased to have earned profit sharing revenues for a second consecutive quarter, which demonstrates the value of our profit sharing arrangements.

Although market conditions remain soft, we remain positive on the fundamentals of the product tanker market, as the improving supply side and the expected tonne mile demand growth should continue to drive period demand for product tankers and positively affect the future outlook of our cash flows.

“Mr Lazaridis concluded: “We remain committed to our $0.93 per unit annual distribution guidance going forward, and we will continue to enhance our financial flexibility to pursue growth opportunities and forge a pathway to distribution growth as the underlying tanker market recovers.”

Appendix A – Reconciliation of Non-GAAP Financial Measure

(In thousands of U.S. dollars)

Description of Non-GAAP Financial Measure – Operating Surplus

Operating Surplus represents net income adjusted for non-cash items such as depreciation and amortization expense and deferred revenue. In prior periods the Partnership designated a separate reserve in its calculation of Operating Surplus for “Replacement Capital Expenditures.” The intent of this reserve is to invest, rather than distribute, an amount of cash flow each quarter so that the Partnership will be able to replace vessels in its fleet as those vessels reach the end of their useful lives. Based on current estimates of future vessel replacement costs, prior levels of Replacement Capital Expenditure reserves and investment returns from previous Replacement Capital Expenditure reserves, the Board of Directors has determined not to reserve additional Replacement Capital Expenditures for the third quarter. The Board of Directors will continue to review its Replacement Capital Expenditure requirements on a quarterly basis. Operating Surplus is a quantitative standard used in the publicly-traded partnership investment community to assist in evaluating a partnership’s ability to make quarterly cash distributions. Operating Surplus is a non-GAAP financial measure and should not be considered as an alternative to net income or any other indicator of the Partnership’s performance required by accounting principles generally accepted in the United States. The table below reconciles Operating Surplus to net income for the three-months period ended September 30, 2012.
