TerraForm Power Reports Third Quarter 2017 Results

BETHESDA, Md., Nov. 09, 2017 (GLOBE NEWSWIRE) -- TerraForm Power, Inc. (Nasdaq:TERP) (“TerraForm Power”) today reported financial results for the three months ended September 30, 2017.

“We are very excited about the prospects for TerraForm Power,” said John Stinebaugh, CEO of TerraForm Power. “With our high-quality fleet of solar and wind assets and the support of our sponsor, we are confident that we can deliver an attractive total return to our shareholders comprised of a dividend backed by the stable cash flow from our assets and growth that is sustainable over the long term.”

Financial Results and Operations

During the third quarter, our portfolio performed slightly below expectations, delivering adjusted EBITDA and CAFD of $109 million and $25 million, respectively. This represents a decrease of $10 million and $9 million, respectively, compared to the same period last year when we delivered adjusted EBITDA and CAFD of $119 million and $34 million, respectively. The decrease was largely due to unusually weak wind resource, which was ~20% below average for the quarter, resulting in a 13% decrease in total generation compared to the prior year. Wind resource was particularly low at our Hawaii projects, which have a higher than average contract price. Solar resource was also ~5% below normal levels. During the quarter, our fleet availability of 96% continued to show improvement and has further room to increase as we complete the transition to stand alone operations.

After quarter end, we signed an EPC contract to upgrade the batteries at one of our Hawaii wind projects where we are replacing lead acid batteries with lithium ion batteries. Due to lower maintenance expense associated with these new batteries, we expect to earn ~20% unlevered return on the investment of $11 million. In addition, we believe there may be opportunities in the future to expand our battery farm in order to provide further ancillary services for the local utility.

During the quarter, we revised our definition of CAFD to adjusted EBITDA minus cash distributions to non-controlling interest, annualized interest and project-level amortization payments and average annualized long-term sustaining capital expenditures required to maintain reliability and efficiency of our assets, plus any operating items that are representative of our core business operations. We revised our definition as we believe it provides a more meaningful measure for investors to evaluate our financial and operating performance and ability to pay dividends. We encourage you to review the discussion regarding the use of non-GAAP measures at the end of this press release for more detail.

TerraForm Power’s Value Proposition

Our goal is to deliver a total return of approximately 12% to shareholders that is sustainable over the long term. We expect this total return will be comprised of an attractive dividend yield, supported by a payout ratio of 80-85% of CAFD, plus dividend per share growth of 5-8%. Over the next five years, we see multiple paths to achieving this growth plan and delivering compelling returns to our investors.

1) Margin Enhancements

We believe there is significant opportunity to enhance our cash flow through productivity enhancements. Within the first year, we are targeting approximately $10 million of cost savings by streamlining our organization structure. We are in the process of implementing a structure which is flatter and eliminates duplicative functions. In addition, we are planning to automate a number of processes that are currently very labor intensive and in-source asset management and certain back office functions.

Over the next 2 to 3 years, we are targeting an additional $15 million in cost savings through reductions in O&M expense of $2 per MWh. We believe these O&M cost savings are achievable in part because we have a number of legacy service agreements in our wind fleet with prices that are significantly above current market. Over the past few years, there has been increased competition in the service sector as OEMs have been competing to gain market share by offering contracts that offer both greater coverage as well as lower rates as compared to those in our legacy agreements. Alternatively, we are exploring whether we can achieve greater benefits by adopting an in-sourcing operating model that leverages Brookfield’s experience in establishing an organization to self-perform its renewable power O&M. We are pleased that we have two paths to achieve our cost savings objectives. Whether we recontract with OEMs or in-source will ultimately depend upon which option offers the best combination of lowest cost, risk mitigation and flexibility for our operations. In total, we expect these margin enhancements to provide cash flow increases to largely fund our dividend per share growth targets through 2020.

2) Organic Growth

In addition to cost savings, we are very focused on developing a robust organic growth pipeline comprised of opportunities to invest in our existing fleet on accretive basis as well as add-on acquisitions across our scope of operations. We have identified several compelling opportunities to invest in our fleet, including asset repowerings, site expansions and potentially adding energy storage to existing sites.

There are potential opportunities to repower several of our wind farms in the Northeast and Hawaii by replacing older turbines with new turbines that have increased rotor diameter and superior power generation. With these repowering opportunities, we would be able to utilize existing infrastructure such as the wind farm’s substation, electrical collection systems and potentially its towers, subject to providing necessary reinforcement to the foundations. The preliminary economics for these projects are quite compelling, as they are able to generate incremental power at much lower cost compared to new, greenfield wind projects. However, we will be disciplined and only plan to proceed if we are able to secure long term contracts that mitigate the price risk of these projects.

Another opportunity for organic growth is the potential repowering of projects in our distributed generation solar fleet. Our distributed generation projects typically sell power to customers “behind the meter” at rates that are at a discount to their utility rate. As solar panel costs have declined significantly over the last several years and the efficiency of the panels has increased, there may be opportunities to replace older panels with higher output, lower cost modules as well as to expand the footprint of our solar arrays. We believe this type of repowering represents a “win-win” situation, as our corporate and municipal customers would see even greater savings on their electricity bill, and TerraForm Power would be able to earn attractive returns on its incremental capital investment.

In addition to these opportunities, we also will seek to develop relationships with undercapitalized, private developers that have local expertise and traction in key markets. With Brookfield’s support, we should be able to offer these smaller developers capital as well as assistance in developing their projects. In return, we would look to secure a right of first offer on these projects. We believe these relationships should produce add-on acquisitions with attractive returns compared to auction processes.

We look forward to providing further updates on these organic growth initiatives as they progress.

3) Value-Oriented Acquisitions

We are currently evaluating a number of acquisition opportunities, leveraging Brookfield’s significant business development team in our target markets of North America and Western Europe. With the relationships that Brookfield has developed, its team has been very effective at sourcing off-market transactions at more attractive valuations than auction processes. Brookfield has a track record of executing multi-faceted transactions such as take-privates and recapitalizations that have historically enabled it to acquire high quality assets at attractive relative values.

Furthermore, TerraForm Power has a right of first offer (ROFO) to acquire renewable power assets in North America and Western Europe owned by Brookfield and its affiliates. The ROFO portfolio currently stands at 3,500 MW. Over time, as Brookfield entities look to sell these assets, TerraForm Power will have the opportunity to make offers for these assets and potentially purchase them if the prices meet our investment objectives.

We believe that TerraForm Power will be able to achieve its dividend growth and total return objectives over the next five years from cost savings and investments in organic growth opportunities. Our five-year business plan requires a modest amount of equity issuance of ~$100 million. This will allow us to be patient and disciplined, and we will only pursue larger, value-oriented acquisitions to the extent that they provide upside to our business plan.

Balance Sheet

Since the Brookfield transaction was announced in March, we have taken steps to strengthen our balance sheet and bolster our liquidity. This progress was recently acknowledged when we received upgrades in our corporate credit rating to BB- from S&P and B1 from Moody’s. In the past six months, we have repaid over $450 million of debt with proceeds from asset sales and free cash flow. With the close of the Brookfield transaction, we received a change of control waiver for our $1.25 billion of unsecured bonds and executed a $450 million revolving credit facility with relationship banks in replacement of our previous facility. In early November, we issued a $350 million term loan that was used to repay an intermediate holdco loan, simplifying our capital structure. We are very pleased with the execution of this financing, which we upsized by $50 million and priced at LIBOR + 275, a tightening of 75 basis points below initial price guidance. We believe this is an affirmation of Brookfield’s sponsorship and our plan to further strengthen our balance sheet over time

With the repayment of the intermediate holdco loan, there will no longer be any debt between our projects and our corporate debt. Going forward, we intend to reduce corporate leverage by raising project debt on certain of our unlevered projects and using the proceeds to repay corporate debt. As we grow, we expect to finance acquisitions primarily using non-recourse debt with investment grade metrics, further deleveraging our balance sheet. Over the medium term, our objective is to reduce our corporate debt to cash flow available for debt service (CFADS) ratio to between 4-5 times.

Reconciliation of Non-GAAP Measures

Adjusted Revenue, Adjusted EBITDA and CAFD are supplemental non-GAAP measures that should not be viewed as alternatives to GAAP measures of performance, including revenue, net income (loss), operating income or net cash provided by operating activities. Our definitions and calculation of these non-GAAP measures may not necessarily be the same as those used by other companies. These non-GAAP measures have certain limitations, which are described below, and they should not be considered in isolation. We encourage you to review, and evaluate the basis for, each of the adjustments made to arrive at Adjusted Revenue, Adjusted EBITDA and CAFD.

Calculation of Non-GAAP Measures

We define adjusted revenue as operating revenues, net, adjusted for non-cash items including unrealized gain/loss on derivatives, amortization of favorable and unfavorable rate revenue contracts, net and other non-cash revenue items.

We define adjusted EBITDA as net income (loss) plus depreciation, accretion and amortization, non-cash general and administrative costs, interest expense, income tax (benefit) expense, acquisition related expenses, and certain other non-cash charges, unusual or non-recurring items and other items that we believe are not representative of our core business or future operating performance.

We define “cash available for distribution” or “CAFD” as adjusted EBITDA (i) minus cash distributions paid to non-controlling interests in our renewable energy facilities, if any, (ii) minus annualized scheduled interest and project level amortization payments in accordance with the related borrowing arrangements, (iii) minus average annual sustaining capital expenditures (based on the long-sustaining capital expenditure plans) which are recurring in nature and used to maintain the reliability and efficiency of our power generating assets over our long-term investment horizon, (iv) plus or minus operating items as necessary to present the cash flows we deem representative of our core business operations.

As compared to the preceding period, we revised our definition of CAFD to (i) exclude adjustments related to deposits into and withdrawals from restricted cash accounts, required by project financing arrangements, (ii) replace sustaining capital expenditures payment made in the year with the average annualized long-term sustaining capital expenditures to maintain reliability and efficiency of our assets, and (iii) annualized debt service payments. We revised our definition as we believe it provides a more meaningful measure for investors to evaluate our financial and operating performance and ability to pay dividends. For items presented on an annualized basis, we will present actual cash payments as a proxy for an annualized number until the period commencing January 1, 2018.

Furthermore, to provide investors with the most appropriate measures to assess the financial and operating performance of our existing fleet and the ability to pay dividends in the future, we have excluded results associated with our UK solar and Residential portfolios, which were sold in 2017, from adjusted revenue, EBITDA and CAFD reported for all periods presented.

Use of Non-GAAP Measures

We disclose Adjusted Revenue because it presents the component of our operating revenue that relates to the energy production from our plants, and is, therefore, useful to investors and other stakeholders in evaluating the performance of our renewable energy assets and comparing that performance across periods in each case without regard to non-cash revenue items.

We disclose Adjusted EBITDA because we believe it is useful to investors and other stakeholders as a measure of financial and operating performance and debt service capabilities. We believe Adjusted EBITDA provides an additional tool to investors and securities analysts to compare our performance across periods and among us and our peer companies without regard to interest expense, taxes and depreciation and amortization. Adjusted EBITDA has certain limitations, including that it: (i) does not reflect cash expenditures or future requirements for capital expenditures or contractual liabilities or future working capital needs, (ii) does not reflect the significant interest expenses that we expect to incur or any income tax payments that we may incur, and (iii) does not reflect depreciation and amortization and, although these charges are non-cash, the assets to which they relate may need to be replaced in the future, and (iv) does not take into account any cash expenditures required to replace those assets. Adjusted EBITDA also includes adjustments for goodwill impairment charges, gains and losses on derivatives and foreign currency swaps, acquisition related costs and items we believe are infrequent, unusual or non-recurring, including adjustments for general and administrative expenses we have incurred as a result of the SunEdison bankruptcy.

We disclose CAFD because we believe cash available for distribution is useful to investors in evaluating our operating performance and because securities analysts and other stakeholders analyze CAFD as a measure of our financial and operating performance and our ability to pay dividends. CAFD is not a measure of liquidity or profitability, nor is it indicative of the funds needed by us to operate our business. CAFD has certain limitations, such as the fact that CAFD includes all of the adjustments and exclusions made to Adjusted EBITDA described above.

The adjustments made to Adjusted EBITDA and CAFD for infrequent, unusual or non-recurring items and items that we do not believe are representative of our core business involve the application of management judgment, and the presentation of Adjusted EBITDA and CAFD should not be construed to infer that our future results will be unaffected by infrequent, non-operating, unusual or non-recurring items.

In addition, these measures are used by our management for internal planning purposes, including for certain aspects of our consolidated operating budget, as well as evaluating the attractiveness of investments and acquisitions. We believe these Non-GAAP measures are useful as a planning tool because it allows our management to compare performance across periods on a consistent basis in order to more easily view and evaluate operating and performance trends and as a means of forecasting operating and financial performance and comparing actual performance to forecasted expectations. For these reasons, we also believe these Non-GAAP measures are also useful for communicating with investors and other stakeholders.

a) Represents unrealized (gain) loss on commodity contracts associated with energy derivative contracts that are not designated as hedges for accounting purposes whereby the change in fair value is recorded in operating revenues, net. The amounts added back represent changes in the value of the energy derivative related to future operating periods, and are expected to have little or no net economic impact since the change in value is expected to be largely offset by changes in value of the underlying energy sale in the spot or day-ahead market.

b) Represents net amortization of purchase accounting related intangibles arising from past business combinations related to favorable and unfavorable rate revenue contracts.

c) Primarily represents recognized deferred revenue related to the upfront sale of investment tax credits.

d) Includes increases within operating revenues due to net amortization of favorable and unfavorable rate revenue contracts as detailed in the reconciliation of Adjusted Revenue.

e) Pursuant to the management services agreement, SunEdison agreed to provide or arrange for other service providers to provide management and administrative services to us. In the three and nine months ended September 30, 2016 we accrued $3.4 million and $8.4 million, respectively, of routine G&A services provided or arranged by SunEdison under the Management Services Agreement that were not reimbursed by TerraForm Power and were treated as an addback in the reconciliation of net income (loss) to Adjusted EBITDA. In addition, non-operating items and other items incurred directly by TerraForm Power that we do not consider indicative of our core business operations are treated as an addback in the reconciliation of net income (loss) to Adjusted EBITDA. These items include extraordinary costs and expenses related primarily to restructuring, legal, advisory and contractor fees associated with the bankruptcy of SunEdison and certain of its affiliates (the “SunEdison bankruptcy”) and investment banking, legal, third party diligence and advisory fees associated with the Brookfield transaction, dispositions and financings. The Company’s normal general and administrative expenses, paid by Terraform Power, are the amounts shown below and were not added back in the reconciliation of net income (loss) to Adjusted EBITDA:

f) Represents other non-cash items as detailed in the reconciliation of Adjusted Revenue and associated footnote and certain other items that we believe are not representative of our core business or future operating performance, including but not limited to: acquisition related costs, impairment charges, loss (gain) on FX, loss on investments and receivables with affiliate, and loss on extinguishment of debt.

g) Represents project-level and other interest payments and interest income attributed to normal operations. The reconciliation from Interest expense, net as shown on the Consolidated Statement of Operations to Interest payments applicable to CAFD is as follows:
