Marlin Midstream Partners, LP Reports Second Quarter 2013 Financial Results for Private Company Covering Pre-IPO Period

HOUSTON, September 4, 2013 /GlobeNewswire/ — Marlin Midstream Partners, LP (NASDAQ: FISH), a Delaware limited partnership (“Marlin” or “the Partnership”), today announced financial results for the second quarter ended June 30, 2013.

Marlin completed its initial public offering on July 31, 2013. In connection with the offering, Marlin’s sponsor NuDevco Partners, LLC and its affiliates conveyed to the Partnership Marlin Midstream, LLC, a midstream energy company offering natural gas gathering, processing and transportation services, and Marlin Logistics, LLC, a crude oil logistics company offering crude oil transloading services. As such, Marlin’s historical condensed combined financial statements prior to the IPO are attributable to its predecessors Marlin Midstream, LLC and Marlin Logistics, LLC. Following the closing of the IPO, Marlin entered into additional fee-based commercial agreements with an affiliate of its sponsor, Associated Energy Services, LP (“AES”), all of which include minimum volume commitments and annual inflation adjustments.

Second Quarter 2013 Financial Results

For the second quarter ended June 30, 2013, Marlin reported gross margin of $7.6 million, an increase of 46%, compared to gross margin of $5.2 million, for the second quarter of 2012. The gross margin increase is attributable to increased throughput under fixed fee contracts and the completion of the 11-mile Oak Hill Lateral pipeline. Post-IPO, the vast majority of gross margin will be generated under fee-based, minimum volume commitment commercial agreements.

Net loss decreased to $1.2 million for the second quarter of 2013, compared to net loss of $3.1 million for the second quarter of 2012. Adjusted EBITDA totaled $2.3 million, compared to adjusted EBITDA of $1,000 for the second quarter of 2012.

As of June 30, 2013, cash and cash equivalents totaled $2.5 million compared to $5.6 million at December 31, 2012. Total debt was $130.9 million at June 30, 2013. Using net proceeds from the IPO of $128.6 million (after underwriting discount and structuring fees), the Partnership repaid its existing credit facility of approximately $121.9 million and an outstanding revolving credit facility of approximately $10.0 million, settled the existing interest rate swap liability of approximately $0.1 million, and simultaneously drew down $25.0 million on a new credit facility.

CEO Commentary

“We appreciate the strong support we received from our new unitholders that contributed to our successful, oversubscribed initial public offering in July,” said Chairman and CEO W. Keith Maxwell, III. “We have

Marlin Midstream Partners, LP

Page 2 of9

established an incentivized sponsorship structure, with a management ownership stake of 61%, that is closely aligned with investor interests. Proceeds from the offering were used to repay existing debt, and we now have among the lowest leverage ratios of any MLP in the industry. Our financial flexibility will enable us to execute our growth and value creation strategies through attractive dropdowns from our sponsor and multiple other growth opportunities.

“During the second quarter, which ended prior to our IPO, we delivered strong gross margin performance reflecting the strategic intention to de-risk our business by focusing on a fee-based cash flow strategy,” Mr. Maxwell continued. “We expect this trend to continue as the minimum volume commitments under our commercial agreements drive substantially all of our gross margin going forward. Additionally, the second quarter does not include the impact of key material contracts with our affiliates established at the close of the IPO. Combined, our fee-based commercial agreements for gathering, processing and transloading will drive fixed-fee cash flow with limited commodity exposure for distribution to our unitholders.”

Quarterly Distributions

Marlin’s partnership agreement provides for a minimum quarterly distribution of $0.35 per unit for each whole quarter, or $1.40 per unit on an annualized basis. Quarterly distributions will commence following the third quarter ending September 30, 2013, which will represent the first partial quarter of distributable cash flow subsequent to Marlin’s IPO on July 31, 2013. Marlin targets a total coverage ratio of 1.10x to support distributions.

Capital Expenditures

For the six months ended June 30, 2013 and 2012, Marlin incurred a total of $1.0 million and $1.3 million, respectively, for maintenance capital expenditures and incurred a total of $8.3 million and $4.6 million, respectively, for expansion capital expenditures.

Subsequent Events

Credit Facility

On July 31, 2013 concurrently with the closing of the IPO, the Partnership entered into a new $50.0 million senior secured revolving credit facility which matures on July 31, 2017. If no event of default occurs, the Partnership has the right, subject to approval by the administrative agent and certain lenders, to increase the borrowing capacity under the new revolving credit facility to up to $150.0 million. The new revolving credit facility is available to fund expansions, acquisitions and working capital requirements for operations and general corporate purposes. As noted above, Marlin drew down $25.0 million on the new credit facility simultaneously with the closing of the IPO.

New Contracts

At the closing of the IPO, the Partnership entered into key material contracts which will be reflected in the Partnership’s financial results beginning with the quarter ending September 30, 2013:

• A three-year fee-based gathering and processing agreement with AES at the Panola County processing facilities. Under this agreement, AES will pay a fixed fee per Mcf (subject to an annual inflation adjustment)

Marlin Midstream Partners, LP

for gathering, treating, compression and processing services and a per gallon fixed fee for NGL transportation services. The agreement will provide for a minimum volume commitment of 80 MMcf/d that, at the option of AES and subject to available capacity at the Panola facilities, may be increased to 100 MMcf/d.

• Three, three-year fee-based transloading services agreements with AES at the Wildcat and Big Horn facilities. Under these agreements, AES will pay a fixed fee per barrel. The agreements will provide for a minimum volume commitment of 15,160 Bbls/d at the Wildcat facility and 11,390 Bbls/d at the Big Horn facility.

Forward-Looking Statements

This press release may contain forward-looking statements concerning Marlin’s operations, economic performance and financial condition. These statements can be identified by the use of forward-looking terminology including “may,” “will,” “believe,” “expect,” “anticipate,” “estimate,” “continue,” or other similar words. These statements discuss future expectations, contain projections of results of operations or financial condition or include other “forward-looking” information. Although Marlin believes that the expectations reflected in such forward-looking statements are reasonable, the Partnership can give no assurance that such expectations will be realized.

These forward-looking statements involve risks and uncertainties. Important factors that could cause actual results to differ materially from expectations include, but are not limited to, the following risks and uncertainties:

• the volume of natural gas we gather and process and the volume of NGLs we transport;

Page 4 of9

• the volume of crude oil that we transload;

• the level of production of crude oil and natural gas and the resultant market prices of crude oil, natural gas and NGLs;

• the level of competition from other midstream natural gas companies and crude oil logistics companies in our geographic markets;

• the level of our operating expenses;

• regulatory action affecting the supply of, or demand for, crude oil or natural gas, the transportation rates we can charge on our pipelines, how we contract for services, our existing contracts, our operating costs or our operating flexibility;

• capacity charges and volumetric fees that we pay for NGL fractionation services;

• realized pricing impacts on our revenues and expenses that are directly subject to commodity price exposure;

• damage to pipelines, facilities, plants, related equipment and surrounding properties caused by hurricanes, earthquakes, floods, fires, severe weather, explosions and other natural disasters and acts of terrorism including damage to third party pipelines or facilities upon which we rely for transportation services;

• outages at the processing or fractionation facilities owned by us or third parties caused by mechanical failure and maintenance, construction and other similar activities;

• leaks or accidental releases of products or other materials into the environment, whether as a result of human error or otherwise;

• the level and timing of our expansion capital expenditures and our maintenance capital expenditures;

• the cost of acquisitions, if any;

• the level of our general and administrative expenses, including reimbursements to our general partner and its affiliates for services provided to us;

• our debt service requirements and other liabilities;

• fluctuations in our working capital needs;

• our ability to borrow funds and access capital markets;

• restrictions contained in our debt agreements;

• the amount of cash reserves established by our general partner;

• other business risks affecting our cash levels; and

• other factors discussed below and elsewhere in “Risk Factors” in our Prospectus.

Such risks and uncertainties could cause actual results to differ materially from those contained in any forward-looking statement. Except as required by law, Marlin undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Gross Margin, Adjusted EBITDA and Distributable Cash Flow

Marlin uses gross margin, or revenues less cost of revenues, as the primary performance measure. Gross margin represents our profitability without regard to commodity sales and purchases, which we believe are not significant components of our operations. Marlin also uses adjusted EBITDA to analyze its performance and defines it as net income (loss) before interest expense (net of amounts capitalized) or interest income, state franchise tax, depreciation expense and any gain/loss from interest rate derivatives. Although Marlin has not quantified distributable cash flow on a historical basis, after the closing of the IPO Marlin intends to compute and present this measure, defined as adjusted EBITDA plus interest income, less cash paid for interest expense and maintenance capital expenditures.

Marlin Midstream Partners, LP

Page 5 of9

Gross margin, adjusted EBITDA and distributable cash flow are non-GAAP supplemental financial measures that management and external users of Marlin’s condensed combined financial statements, such as industry analysts, investors, commercial banks and others, may use to assess:

• the financial performance of Marlin’s assets without regard to financing methods, capital structure or historical cost basis;

• the ability of Marlin’s assets to generate earnings sufficient to support the decision to make cash distributions to the unitholders and general partner;

• the ability to fund capital expenditures and incur and service debt;

• Marlin’s operating performance and return on capital as compared to those of other companies in the midstream energy sector, without regard to financing or capital structure; and

• the attractiveness of capital projects and acquisitions and the overall rates of return on alternative investment opportunities.

Marlin’s partnership agreement requires that, within 45 days after the end of each quarter, beginning with the quarter ending September 30, 2013, all of Marlin’s available cash be distributed to unitholders of record on the applicable record date. Marlin’s cash distribution for the period from the completion of the IPO through September 30, 2013 will be adjusted based on the actual length of the period.

Note Regarding Non-GAAP Financial Measures

Gross margin and adjusted EBITDA are not financial measures presented in accordance with GAAP. Marlin believes that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing Marlin’s financial condition and results of operations. The GAAP measure most directly comparable to gross margin is operating income. The GAAP measure most directly comparable to adjusted EBITDA is net income. These measures should not be considered as an alternative to operating income, net income, or any other measure of financial performance presented in accordance with GAAP. Each of these non-GAAP financial measures has important limitations as an analytical tool because it excludes some but not all items that affect net income. You should not consider these non-GAAP financial measures in isolation or as a substitute for analysis of Marlin’s results as reported under GAAP. Additionally, because each of these non-GAAP financial measures may be defined differently by other companies in the industry, Marlin’s definition of them may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.
