Summit Midstream Partners, LP reported its Q4 and full year 2020 results.
Summit reported net income of $103.0 million, adjusted EBITDA of $61.8 million and DCF of $44.8 million. Net income for the quarter included a $124.1 million gain from early extinguishment of debt related to the open market repurchase of senior unsecured notes and the consensual debt discharge and restructuring of a subsidiary's $155.2 million term loan ("GP Term Loan Restructuring"), partially offset by non-cash charges for a $17.0 million loss contingency and a $5.1 million asset impairment related to an $8.0 million sale of compressor equipment, which closed in January 2021.
Fourth quarter 2020 operated natural gas volume throughput averaged 1,436 million cubic feet per day ("MMcf/d") and liquids volume throughput averaged 71 thousand barrels per day ("Mbbl/d"). Operated natural gas volumes increased by 3.2% relative to the third quarter of 2020, largely due to a volume increase of 91 MMcf/d in the Utica Shale segment from a combination of a customer returning 22 MMcf/d of temporarily shut-in production at the end of the third quarter, and seven new well connections in September, partially offset by modest volume throughput declines in other reportable segments. Throughput volumes for the Ohio Gathering segment increased by 42 MMcf/d, net to Summit, or 21.3% over the third quarter of 2020, due to the return of substantially all temporarily shut-in production and higher volumes from 15 new wells that were connected late in the third quarter. Quarterly liquids volume throughput increased by 2.9% over the third quarter of 2020, primarily due to eight new wells that were turned in line during the quarter.
Heath Deneke, President, Chief Executive Officer and Chairman, commented, "Summit's fourth quarter financial results were in line with expectations, and adjusted EBITDA was $2 million ahead of third quarter results. Our full year results fell within our guidance range of $250 million to $260 million that we established in July 2020, to reflect the implications of the global COVID-19 pandemic, lower commodity prices and a slowdown of upstream activity behind our systems. The strong performance of our Utica Shale and Ohio Gathering segments drove overall quarter-over-quarter increases in adjusted EBITDA and volume throughput. On an aggregate basis, these two segments contributed an incremental $2.6 million of quarterly adjusted EBITDA relative to the third quarter of 2020, and each segment had quarterly volume throughput growth of more than 20%. Additionally, with the return of substantially all shut-in production behind the Ohio Gathering system in November, we no longer have any material amount of production that is temporarily shut-in for economic purposes behind any of our assets.
"We executed a number of liability management transactions in the fourth quarter, including the repurchase of $95.6 million face value of our 2025 notes, a cash tender for $75.1 million of our Series A Preferred Units, and the closing of the transformational GP Term Loan Restructuring. In total, since closing the GP Buy-In in May 2020, we have eliminated more than $625 million of recourse fixed capital obligations at SMLP, including the $180.8 million DPPO, and we extinguished our GP's $155.2 million term loan, all at substantial discounts to par. As a result of these actions, our organizational structure and capital structure have been significantly simplified. In December 2020, we completed an amendment to our revolving credit facility that provides additional flexibility to support the next phase of our liability management initiatives. The newly added $400 million junior lien debt basket can be utilized to address our 2022 bond maturities and the increased total leverage covenant of 5.75x provides SMLP with additional cushion to mitigate future uncertainty.
"We continue to make great progress on the Double E project, having received all necessary approvals to proceed with construction, and securing bank financing commitments. Now that we have received the Notice to Proceed from the FERC, we have initiated construction activities and we expect to bring the project online during the fourth quarter of 2021. We continue to expect that Double E will be completed at or below the current $425 million capital budget, of which, approximately $35 million currently remains in unidentified project contingency. In the fourth quarter of 2020, SMLP contributed approximately $6.6 million of cash for its 70% share of Double E capital contributions, resulting in SMLP funding approximately $20 million during the calendar year 2020, and approximately $131 million of total funding from the project's inception through the end of 2020. In 2021, we expect to finance SMLP's estimated $150 million share of Double E capital expenditures with funds from the $175 million of new, non-recourse senior secured credit facilities which have been committed by leading commercial banks.
"In 2020, we successfully executed a robust set of liability management transactions that strengthened the balance sheet and created financial flexibility to offset the potential for a prolonged challenging macro environment, while generating long term value for our unitholders. We expect that 2021 will be a trough year for Summit, as many of our customers have significantly reduced drilling and completion activities behind our systems, particularly during the first half of the year. As a result, we expect approximately 45 to 75 new well connections in 2021, which is materially less than the 104 and 262 wells connected in 2020 and 2019, respectively. We also anticipate MVC shortfall payment step-downs of approximately $10 million in 2021, relative to 2020, primarily from customers in the Piceance and Williston segments. Accordingly, we issued our 2021 adjusted EBITDA guidance range of $210 million to $230 million, which includes a moderate amount of risking to our customer-provided development plans and volume forecasts at the midpoint of the range, Further risking of these plans reflect the low end of the range and if our customers achieve their stated plans, we would expect our financial results to be at the high end of the range.
"Although we are expecting softened customer activity in 2021, we expect to generate sufficient cash, after interest expense and capital expenditures, to reduce outstanding indebtedness by approximately $130 million to $150 million due to the resiliency of our business model. While it is too early to provide guidance for 2022, we foresee several tailwinds that we believe will support increased customer activity behind our systems, including an improving outlook on oil and gas prices, more constructive capital markets and the potential for additional consolidation activity in the upstream sector, all of which should further strengthen customer balance sheets. In the meantime, we will remain focused on maximizing free cash flow, further de-levering the balance sheet and implementing plans to address our upcoming 2022 debt maturities."
SMLP is reiterating its financial guidance for full year 2021 that was released on February 16, 2021, and included the following guidance ranges:
The Partnership believes these guidance ranges reflect a conservative, yet appropriate level of risking to the most recent drill schedules and volume forecasts provided by customers. These projections are subject to risks and uncertainties described in the "Forward-Looking Statements" section at the end of this press release.
Please refer to SMLP's press release issued on February 16, 2021, for additional details regarding Summit's full year 2021 financial guidance.
In the fourth quarter of 2020, SMLP's average daily natural gas throughput for its operated systems increased 3.2% relative to the third quarter of 2020, to 1,436 MMcf/d, and liquids volumes increased 2.9% relative to the third quarter of 2020, to 71 Mbbl/d. SMLP's customers had approximately 37 DUCs in inventory upstream of its systems with line of sight to near-term completions as of December 31, 2020.
Core Focus Areas:As of December 31, 2020, SMLP had $238.9 million of undrawn commitments under its $1.1 billion revolving credit facility, after accounting for a $4.1 million issued but undrawn letter of credit. Subject to covenant limits, our available borrowing capacity at December 31, 2020 totaled approximately $105 million. SMLP also had $15.4 million of cash on hand as of December 31, 2020.
Based upon the terms of SMLP's revolving credit facility and total outstanding debt, net of cash, of $1.34 billion (inclusive of $493.5 million of senior unsecured notes), SMLP's total leverage ratio and first lien leverage ratio (as defined in the credit agreement) as of December 31, 2020, were 5.1 to 1.0 and 3.2 to 1.0, respectively, relative to maximum threshold limits of 5.75 to 1.0 and 3.50 to 1.0.
In accordance with certain GAAP requirements, in the fourth quarter of 2020, the Partnership recognized a $17.0 million, non-cash loss contingency accrual related to a previously disclosed incident dating back to a 2015 release of produced water from a pipeline owned by Meadowlark Midstream. Since discovering the pipeline rupture in January 2015, the Partnership and its affiliates have spent nearly $75 million on environmental remediation costs and preventative system improvements associated with this incident. Since then, we have also engaged in discussions with federal and state agencies and the U.S. Department of Justice regarding resolution of potential criminal and civil violations under statutes such as the Clean Water Act. It remains unclear if a resolution to these potential violations could be achieved through a negotiated settlement or through litigation, and the timing of any resolution is unknown. We will continue to provide updates if any material developments occur.
During the fourth quarter of 2020, SMLP made cash investments totaling $6.6 million with respect to its 70% equity investment in Double E. SMLP's 70% share of the total expected Double E capital costs is approximately $300 million, of which approximately $131 million has been funded as of December 31, 2020. In January of 2021, Double E received its Notice to Proceed with construction from the Federal Energy Regulatory Commission and was granted the necessary rights-of-way on federal lands from the Bureau of Land Management. In February 2021, SMLP's wholly-owned, indirect subsidiary, Summit Permian Transmission, LLC, received $175 million of commercial bank commitments to finance development of the Double E pipeline project, which it expects to fully fund SMLP's approximately $150 million of capital contributions for Double E in 2021. The estimated in-service date for Double E continues to be the fourth quarter of 2021.
SMLP billed its customers $22.3 million in the fourth quarter of 2020 related to MVC shortfalls. For those customers that do not have MVC shortfall credit banking mechanisms in their gathering agreements, the MVC shortfall payments are accounted for as gathering revenue in the period in which they are earned. In the fourth quarter of 2020, SMLP recognized $14.0 million of gathering revenue associated with MVC shortfall payments. SMLP also recognized $0.9 million of adjustments to MVC shortfall payments in the fourth quarter of 2020 related to shortfall payment adjustments from customers in the Williston Basin segment and the Piceance Basin segment. SMLP's MVC shortfall payment mechanisms contributed $14.9 million of total adjusted EBITDA in the fourth quarter of 2020.
The board of directors of SMLP's general partner continues to suspend cash distributions payable on its common units and on its 9.50% Series A fixed-to-floating rate cumulative redeemable perpetual preferred units for the period ended December 31, 2020. Unpaid distributions on the Series A preferred units will continue to accrue.
