Northern Tier Reports First Quarter 2015 Results

Highlights:

  • Declares a first quarter distribution of $1.08 per common unit to be paid in cash on May 29, 2015
  • First quarter Adjusted Net Income of $100.4 million and Adjusted EBITDA of $123.2 million
  • First quarter total refinery throughput of 94,108 barrels per day
  • Solid retail contribution with strong fuel margin

TEMPE, Ariz., May 5, 2015 (GLOBE NEWSWIRE) -- Northern Tier Energy LP and its subsidiaries (NYSE:NTI) (collectively, "Northern Tier" or the "Company") today reported first quarter 2015 results. First quarter 2015 Net Income was $111.2 million compared with $71.5 million for the first quarter 2014. Results for the 2015 quarter included a $10.8 million non-cash lower of cost or market ("LCM") inventory adjustment benefit. Excluding the LCM adjustment and other special items, Adjusted Net Income was $100.4 million for the first quarter 2015, compared to $80.9 million in the prior year quarter. Adjusted EBITDA for first quarter 2015 was $123.2 million (excluding the LCM adjustment) compared to $102.6 million for first quarter 2014, primarily due to higher gross margins per barrel, along with higher throughput. A reconciliation of reported earnings to various non-GAAP performance measures can be found in the accompanying tables.

"Results for the first quarter 2015 were strong. Supportive crude oil margins and retail fuel margins resulted in the third consecutive quarter with Adjusted EBITDA exceeding $120 million. With these results, I am pleased to announce a first quarter distribution of $1.08 per unit," said Dave Lamp, President and Chief Executive Officer. "Our growth initiatives continue to evolve into 2015. We approved plans to revamp the No. 2 Crude Unit and ULSD hydrotreater at the St. Paul Park Refinery at a cost of $19 million. We expect these projects would increase our crude oil capacity by 4,000 barrels per day and improve diesel yield by 2%, and generate approximately $10 million per year of incremental Adjusted EBITDA based on 5-year historical average crude oil margins and product differentials. These projects, as well as the desalter projects announced last quarter, are slated for completion in combination with the regular scheduled turnaround planned for the spring of 2016."

First Quarter Operating Segment Highlights

Refining Segment

The refining segment's operating income excluding the LCM adjustment was $112.6 million for first quarter 2015 compared to $97.8 million for the prior year period. Refining gross margin was $19.53 per barrel of throughput for first quarter 2015 ($20.77 per barrel including the LCM adjustment) compared to $18.08 per barrel of throughput for first quarter 2014. Refining Adjusted EBITDA for first quarter 2015 was $123.0 million (excluding the LCM adjustment) compared to $107.0 million for the prior year period. This increase was driven by improved gross margins along with increased throughput and sales volumes. Total throughput was 94,108 barrels per day for first quarter 2015 compared to 92,628 barrels per day for the prior year period. Both periods were impacted by planned and unplanned maintenance activities.

Retail Segment

Retail operating income in first quarter 2015, was $2.4 million (excluding the LCM adjustment), compared to $1.7 million for first quarter 2014. Fuel margins were $0.21 per gallon for first quarter 2015 compared to $0.19 per gallon for the prior year period. Adjusted EBITDA for the first quarter 2015 was $4.3 million (excluding the LCM adjustment) compared to $3.4 million in the first quarter 2014.

The aggregate of fuel gallons sold at company-operated retail stores plus fuel gallons sold to franchisee stores increased 9.2% for the quarter ended March 31, 2015 compared to the first quarter 2014 and 11.2% compared to first quarter 2013. This growth was a result of establishing additional SuperAmerica franchise locations. The number of franchise locations totaled 95 as of March 31, 2015. The Company has added six additional franchise locations so far in 2015 and is targeting additional franchise growth later in the year, as well as opening three company-operated stores in 2015.

Quarterly Distribution

Effective May 5, 2015, the Board of Directors (the "Board") of Northern Tier Energy GP LLC, the general partner of the Company declared a quarterly distribution of $1.08 per unit that will be paid in cash on May 29, 2015 to common unit holders of record as of the close of business on May 18, 2015. Cash available for distribution totaled $100.8 million for first quarter 2015.

Northern Tier Energy LP is a variable distribution master limited partnership. As a result, its quarterly distributions, if any, will vary from quarter-to-quarter as a result of variations in, among other factors, (i) its operating performance, (ii) cash flows caused by fluctuations in the prices it pays for crude oil and other feedstocks and the prices it receives for finished products, (iii) capital expenditures, (iv) potential cash reserves or payments relating to working capital fluctuations and (v) other cash reserves deemed necessary or appropriate by the board of directors of its general partner.

Liquidity and Capital Spending

Northern Tier's primary sources of liquidity are cash generated from operating activities and its asset-based ABL Facility ("ABL"). In September 2014, Northern Tier expanded its ABL from $300 million to $500 million. This expansion was completed in conjunction with the termination of the Company's crude oil intermediation agreement which included the purchase of over one million barrels of crude oil that were previously held by the counterparty to this agreement. As of March 31, 2015, Northern Tier's cash on hand and availability under the ABL amounted to approximately $313 million as compared to approximately $384 million as of December 31, 2014. Capital spending for first quarter 2015 was approximately $6.6 million compared to first quarter 2014 spending of approximately $10 million.

Q2 2015 Operating and Capital Expenditure Guidance

For the second quarter of 2015, Northern Tier projects total throughput of between 95,000 and 99,000 barrels per day at the Saint Paul Park refinery. Direct operating expense per barrel of throughput at the Saint Paul Park refinery is expected to be between $4.80 and $5.30, not including turnaround expenditures. Total capital expenditures for the second quarter are expected to be approximately $19 million and approximately $79 million for the full year 2015. The full year 2015 capital expenditure guidance includes $53 million for discretionary projects. See the accompanying table for additional key metric guidance.

(a) Adjusted EBITDA is not a presentation made in accordance with GAAP and Northern Tier's computation of Adjusted EBITDA may vary from others in its industry. In addition, Adjusted EBITDA contains some, but not all, adjustments that are taken into account in calculating the components of various covenants in the agreements governing Northern Tier's 2020 Secured Notes and ABL. Northern Tier believes the presentation of Adjusted EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in its industry. The calculation of Adjusted EBITDA generally eliminates the effects of financings, income taxes and the accounting effects of significant turnaround activities which many of Northern Tier's peers capitalize and therefore exclude from Adjusted EBITDA. Adjusted EBITDA should not be considered as an alternative to operating income or net income as measures of operating performance. In addition, Adjusted EBITDA is not presented as, and should not be considered, an alternative to cash flow from operations as a measure of liquidity. Adjusted EBITDA is defined as net income (loss) before interest expense, income taxes and depreciation and amortization, adjusted for depreciation from the Minnesota Pipe Line operations, lower of cost or market inventory adjustments, turnaround and related expenses and equity-based compensation expense. Adjusted EBITDA has limitations as an analytical tool and should not be considered in isolation, or as a substitute for analysis of the results as reported under GAAP.

The Company's LCM reserve changed from $73.6 million at December 31, 2014 to $62.8 million at March 31, 2015, resulting in a $10.8 million non-cash benefit recorded within cost of sales.
(c) Capital expenditures include maintenance, replacement, regulatory and expansion capital projects on an accrual basis.
(d) Cash reserves are determined by the Board of Directors of Northern Tier's general partner and are primarily for the purpose of funding turnarounds and discretionary capital projects. Since spending may be significant in any given quarter, reserves are made over several quarters in order to mitigate the impact on cash available for distribution.
(e) Cash available for distribution is a non-GAAP performance measure that Northern Tier believes is important to investors in evaluating its overall cash generation performance. Cash available for distribution should not be considered as an alternative to operating income or net income (loss) as measures of operating performance. In addition, cash available for distribution is not presented as, and should not be considered, an alternative to cash flow from operations as a measure of liquidity. Northern Tier has reconciled cash available for distribution to Adjusted EBITDA and in addition reconciled Adjusted EBITDA to net income. Cash available for distribution has limitations as an analytical tool and should not be considered in isolation, or as a substitute for analysis of the results as reported under GAAP. Northern Tier's calculation of cash available for distribution may differ from similar calculations of other companies in its industry, thereby limiting its usefulness as a comparative measure. Cash available for distribution for each quarter will be determined by the Board of Directors of Northern Tier's general partner following the end of such quarter.

(f) Refining gross margin is calculated by subtracting refining costs of sales from total refining revenues. Refining gross margin excluding lower of cost or market ("LCM") inventory adjustment is calculated by adding back the non-cash LCM inventory adjustment to refining gross margin. Refining gross margin and refining gross margin excluding LCM are non-GAAP performance measures that Northern Tier believes are important to investors in evaluating its refining segment performance as a general indication of the amount above its cost of products that it is able to sell refined products. Northern Tier's calculation of refining gross margin and refining gross margin excluding LCM may differ from similar calculations of other companies in its industry, thereby limiting its usefulness as a comparative measure.

(k) Annual forecasted EBITDA is a non-GAAP financial measure that Northern Tier believes is an important measure that management and external users of the financial statements may use to assess the No. 2 Crude Unit Revamp and ULSD Hydrotreater projects' operating performance and its ability to generate sufficient cash flow to make distributions to Northern Tier's unitholders.
