⁽³⁾CAFD per share is calculated using CAFD divided by the weighted average diluted Class A common stock shares outstanding.

Growth Initiatives

During 2019, we continued to execute our growth strategy, focusing on organic growth initiatives and value-based, third-party acquisitions.

With regards to repowerings of wind farms, we made substantial progress on our two New York projects (Cohocton and Steel Winds) totaling ~160 MW. We secured all New York state permits required to commence the repowerings and received a non-materiality determination from NYISO, ensuring that we will not have to re-open our interconnection agreements to accommodate the ~25% increase in energy from this initiative. Finally, we executed Payment in Lieu of Taxes (PILOT) agreements with local municipalities for both projects ensuring favorable tax treatment over the long-term. In terms of next steps, we are currently negotiating key commercial terms of an agreement with GE to secure 80% PTC safe-harbored turbines, and we are in negotiations regarding energy and renewable energy credit hedge agreements with a combination of corporate customers and large financial institutions. The New York repowerings are expected to earn a blended, unlevered after-tax return in the low-teens and de-risk cashflow from these facilities by replacing Clipper turbines, which historically have had operational issues.

The biggest acquisition that we executed in 2019 was our ~$720 million acquisition of the AltaGas DG portfolio which closed in September, adding approximately ~320 MW of DG solar assets to our existing portfolio. We expect to earn a levered return on equity within our targeted range of 9% to 11% on this acquisition. We now own ~750 MW of DG, making Terraform Power one of the largest DG operators in the United States. Diversified across 27 states, the District of Columbia, Puerto Rico and Canada, and with over 300 commercial and industrial customers, our DG portfolio is comprised of assets with an average age of 5 years that have power purchase agreements with an average remaining term of approximately 15 years.

In November, we entered into an agreement to acquire a 100 MW portfolio of regulated Concentrated Solar Power (“CSP”) projects in Spain for an equity investment of $103 million. The Portfolio is comprised of two ~50 MW CSP plants with nine hours of storage capacity that have an average remaining regulatory life of 19 years. As part of the transaction, we are acquiring the operating company which provides O&M services to the plants and is regarded as one of the best CSP operators in the Spanish market. We closed this acquisition in February of this year. In December, we signed and closed the acquisition of 45 MW of regulated solar Photovoltaic (“PV”) assets in Spain for an equity investment of $60 million. The portfolio is comprised of nine plants that have a remaining regulatory life of 21 years. We expect to earn a blended return on equity on these investments that exceeds our targeted range of 9% to 11%.

Operations

During 2019, we continued to execute our plan of outsourcing O&M of our wind and solar fleets to best-in-class operators in order to lower our costs and shift operating risk through robust performance guarantees. As of year-end, we have successfully transitioned operatorship of 15 of 16 North American wind farms to GE, positioning Terraform Power to capture the lion’s share of the $20 million of expected annualized cost reductions. Negotiations are ongoing with tax equity investors of the final wind farm, and our expectation is to transition this project to GE by mid-year. Furthermore, we are pleased to report that as of October 1, performance guarantees are in effect for all 15 wind farms that GE is operating.

In Spain, we replaced the legacy operator for all of our wind farms and executed LTSAs with the original equipment manufacturers. In the case of Uruguay and Portugal, we renegotiated the existing LTSAs to improve economics and drive improvements in the plants’ operational performance. We expect to lock-in annualized cost savings of $4 million, with attractive availability guarantees, from these LTSA agreements.

In November, we signed a Framework Agreement with SMA to provide O&M services for our North American solar fleet. As a result, ~1,000 MW of our solar fleet will be covered by the agreement, with expected annualized cost savings of ~$5 million. The Framework Agreement will help us mitigate operational risk through performance guarantees and provides incentives for SMA to identify opportunities to make accretive investments in our fleet, such as repowerings and upgrades of inverters. The Framework Agreement also includes a volume discount, whereby we can add additional assets, such as our recently acquired DG portfolio, at attractive pricing, provided we meet or exceed certain volume thresholds. In January of 2020, we signed project LTSAs for ~510 MW of our portfolio and expect to fully transition these projects to SMA by April. Upon receipt of consent from project lenders and tax equity investors, we are targeting execution of the balance of the LTSAs and transfer of operations to SMA by mid-2020.

In February of 2020, we signed an amendment to our O&M agreement with Cobra Instalaciones y Servicios (“Cobra”) for five of our CSP plants in Spain. Under the amended agreement, Cobra has agreed to pay for deferred maintenance that will improve the physical condition of the plants and increase production. In addition, the amended agreement provides for better alignment of incentives between owner and operator. Cobra has agreed to increase the minimum production guarantee from the plants in exchange for greater sharing of upside above various production thresholds.

Financial Results

Net (Loss) Income attributable to Class A shareholders was $(149) million in 2019 compared to $12 million in 2018, primarily due to higher allocation of losses to non-controlling interests in the prior year related to the reduction in U.S. corporate tax rates.

In 2019, we generated CAFD of $173 million, which was $47 million greater than 2018. On a per share basis, CAFD was $0.81, which was a 17% increase over the prior year. The increase was largely attributable to a full year contribution from the Saeta acquisition, which closed in June of 2018, a partial year contribution from our recent DG acquisition and cost savings from the implementation of LTSAs in North America and Europe. This was offset by lower availability from our North American wind fleet, as we accelerated deferred maintenance in order to implement the LTSAs, as well as lower realized prices in North American wind due to contract roll-off and greater negative basis in Texas and a decline in Spanish wholesale market prices.

On a same-store basis, TerraForm Power generated Adjusted EBITDA in 2019 of $413 million, which was an increase of $7 million or 2% compared to 2018. The increase in same-store Adjusted EBITDA is mainly due to reduced O&M costs and liquidated damages as a result of performance guarantees attributable to our LTSAs with GE.

Liquidity Update

In 2019, we continued to capitalize on attractive market conditions to bolster our liquidity and position ourselves for growth. In October, we issued $300 million of equity priced at $16.77 per share representing a 50% premium to our price at the beginning of 2019. This issue was comprised of our inaugural $250 million secondary public offering as well as a concurrent $50 million private placement to Brookfield Renewable.

During the year, we were very active on the liability management front at both the corporate and project levels, locking in historically low interest rates. We issued $700 million of 10-year senior notes at a coupon of 4.75% and used the proceeds to repay our $300 million notes due 2025 and our $344 million Term Loan B due 2022. With that refinancing we expect to realize debt service savings of ~$6 million per year and extend our maturity profile such that we have no corporate maturities until 2023. Over the course of 2019, we also completed seven non-recourse debt refinancings totaling $1.6 billion, raising net proceeds of ~$460 million and lowering our weighted average interest rate by ~50 bps.

As a result of these initiatives, our corporate liquidity stood at $1.3 billion as of the end of 2019, including our $500 million sponsor line with Brookfield.

Legal and Regulatory Update

In Spain, Royal Decree Law (“RDL”) 17/2019, which established the new rate of reasonable return for renewable energy was enacted in November and ratified in parliament. According to the RDL, for certain plants already in operation on September of 2013 and that do not have an open litigation process against the Kingdom of Spain, the reasonable return will be extended at the current level of 7.4% for the next two regulatory periods until December 2031. This applies to all of our assets in Spain, excluding the 45 MW of PV solar projects that we acquired in December and the 100 MW of CSP projects that we acquired in February 2020. These plants will earn a 7.1% return for the next six-year regulatory period.

Announcement of Quarterly Distribution

On March 16, 2020, our Board of Directors declared a quarterly distribution with respect to our Class A common stock of $0.2014 per share. The distribution is payable on March 31, 2020, to stockholders of record as of March 27, 2020. This distribution represents our ninth consecutive quarterly distribution payment under Brookfield’s sponsorship.

Reconciliation of Non-GAAP Measures

This communication contains references to Adjusted Revenue, Adjusted EBITDA, and cash available for distribution (“CAFD”), which 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 differ from definitions of Adjusted Revenue, Adjusted EBITDA and CAFD or other similarly titled measures used by other companies. We believe that Adjusted Revenue, Adjusted EBITDA and CAFD are useful supplemental measures that may assist investors in assessing the financial performance of TerraForm Power. None of these Non-GAAP measures should be considered as the sole measure of our performance, nor should they be considered in isolation from, or as a substitute for, analysis of our financial statements prepared in accordance with GAAP, which are available on our website at www.terraform.com, as well as at www.sec.gov. 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 (i) unrealized gain/loss on derivatives, net, (ii) amortization of favorable and unfavorable rate revenue contracts, net, (iii) an adjustment for wholesale market revenues to the extent above or below the regulated price bands, and (iv) other items that we believe are representative of our core business or future operating performance.

We define Adjusted EBITDA as net income (loss) plus depreciation, accretion and amortization, non-operating general and administrative costs, management fees to Brookfield, 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 management fees to Brookfield, (ii) minus cash distributions paid to non-controlling interests in our renewable energy facilities, if any, (iii) minus annualized scheduled interest and project level amortization payments in accordance with the related borrowing arrangements, (iv) 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, (v) plus or minus operating items as necessary to present the cash flows we deem representative of our core business operations.

Use of Non-GAAP Measures

We disclose Adjusted Revenue because it presents the component of operating revenue that relates to energy production from our plants, and is, therefore, useful to investors and other stakeholders in evaluating 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 our 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 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 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 and other stakeholders in evaluating our operating performance and as a measure of our ability to pay distributions. 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's 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 they allow 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.

Includes reductions/(increases) within operating revenues due to net amortization of favorable and unfavorable rate revenue contracts as detailed in the reconciliation of Adjusted Revenue, and losses on disposal of property, plant and equipment.

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 loss to Adjusted EBITDA. These items include, but are not limited to, extraordinary costs and expenses related primarily to IT system arrangements, relocation of the headquarters to New York, and legal, third party diligence, contractor fees and advisory fees associated with acquisitions, dispositions, financings, and other non-recurring activities. TerraForm Power’s normal, recurring general and administrative expenses in Corporate, paid by TerraForm Power, are the amounts shown below and were not added back in the reconciliation of net loss to Adjusted EBITDA:

Operating general and administrative expenses in Corporate		$	9			$	9			$	34			$	29

Represents the Regulated Solar and Wind segment’s Price Band Adjustment to Return on Investment Revenue as dictated by market conditions. To the extent that the wholesale market price is greater or less than a price band centered around the market price forecasted by the Spanish regulator during the preceding three years, the difference in revenues assuming average generation accumulates in a tracking account. The Return on Investment is either increased or decreased in order to amortize the balance of the tracking account over the remaining regulatory life of the assets.

Represents management fee that is not included in Direct operating costs.

Represents other non-cash or non-operating 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: loss/(gain) on foreign exchange (“FX”), unrealized loss on commodity contracts, loss on investments and receivables with affiliate, and one-time blade repairs related to the preparation for GE transition.

Represents unrealized (gain)/loss on commodity contracts associated with energy derivative contracts that are accounted for at fair value with the changes 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.

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

Primarily represents insurance compensation for revenue losses, transmission capacity revenue, and adjustments for solar renewable energy certificate (”SREC”) recognition and other revenue due to timing.

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

$ in millions		Q4 2019			Q4 2018		YTD 2019			YTD 2018

Represents cash distributions paid to non-controlling interests in our renewable energy facilities. The reconciliation from Distributions to non-controlling interests as shown on the Consolidated Statement of Cash Flows to Cash distributions to non-controlling interests, net for the three months December 31, 2019 and 2018 is as follows:

Represents long-term average sustaining capital expenditures to maintain reliability and efficiency of the assets.

Represents other cash flows as determined by management to be representative of normal operations including, but not limited to, wind plant “pay as you go” contributions received from tax equity partners, interconnection upgrade reimbursements, cash tax payments, and recognized SREC gains that are covered by loan agreements.
