OUR CUSTOMERS Most energy consumers are currently beholden to a single power company that provides electricity to them based on household location. Sunrun will give home solar and battery consumers access to better, more affordable products - enabling greater energy choice.  A lower cost structure from greater scale can open more markets and allow lower pricing for customers, accelerating renewable energy adoption. Combining R&D resources and focusing efforts will allow us to accelerate product and service development and offering advanced solutions to more customers in more markets. OUR INVESTORS The acquisition of Vivint Solar adds a complementary direct-to-home sales channel to Sunrun’s platform, increasing the market reach and capabilities. We expect to deliver meaningful cost synergies, estimated at $90 million dollars on an annual basis: including consolidating and optimizing our branch footprint, reducing redundant spending on technology systems, scaling our proprietary racking technology, and through improved supply chain sourcing. We also expect to realize scale benefits from shared corporate functions including accounting, HR, legal and policy. OUR COMMUNITIES Extreme weather due to climate change is increasing, putting immense strain on our energy system. Fossil fuel power plants produce over 30% of carbon pollution in the US. 1 There is an urgent need to decarbonize our energy system. With a combined customer base of nearly 500,000, Sunrun will ultimately be able to network even more systems in more locations to provide greater benefits to the grid and helping to shut down carbon-producing power plants.   The combined company’s increased scale, operating efficiency and combined R&D efforts will help the company accelerate the adoption of renewable energy and benefit more customers.

Glossary of Terms Glossary of Sunrun Terms Customers refers to all parties (i) who have executed Customer Agreements or cash sales agreements with us and (ii) for whom we have internal confirmation that the applicable solar energy system has reached notice to proceed or “NTP”, net of cancellations.  Customer Agreements refers to, collectively, solar power purchase agreements and solar leases. Gross Earning Assets represent the remaining net cash flows (discounted at 6%) we expect to receive during the initial term of our Customer Agreements (typically 20 or 25 years) for systems that have been deployed as of the measurement date, plus a discounted estimate of the value of the Customer Agreement renewal term or solar energy system purchase at the end of the initial term. Gross Earning Assets deducts estimated cash distributions to investors in consolidated joint ventures and estimated operating, maintenance and administrative expenses for systems deployed as of the measurement date. In calculating Gross Earning Assets, we deduct estimated cash distributions to our project equity financing providers. In calculating Gross Earning Assets, we do not deduct customer payments we are obligated to pass through to investors in pass-through financing obligations as these amounts are reflected on our balance sheet as long-term and short-term pass-through financing obligations, similar to the way that debt obligations are presented. In determining our finance strategy, we use pass-through financing obligations and long-term debt in an equivalent fashion as the schedule of payments of distributions to pass-through financing investors is more similar to the payment of interest to lenders than the internal rates of return (IRRs) paid to investors in other tax equity structures. We calculate the Gross Earning Assets value of the purchase or renewal amount at the expiration of the initial contract term assuming either a system purchase or a five year renewal (for our 25-year Customer Agreements) or a 10-year renewal (for our 20-year Customer Agreements), in each case forecasting only a 30-year customer relationship (although the customer may renew for additional years, or purchase the system), at a contract rate equal to 90% of the customer’s contractual rate in effect at the end of the initial contract term. After the initial contract term, our Customer Agreements typically automatically renew on an annual basis and the rate is initially set at up to a 10% discount to then-prevailing power prices. Gross Earning Assets Under Energy Contract represents the remaining net cash flows during the initial term of our Customer Agreements (less substantially all value from SRECs prior to July 1, 2015), for systems deployed as of the measurement date. Gross Earning Assets Under Energy Contract represents the remaining net cash flows during the initial term of our Customer Agreements (less substantially all value from SRECs prior to July 1, 2015), for systems deployed as of the measurement date. Gross Earning Assets Value of Purchase or Renewal is the forecasted net present value we would receive upon or following the expiration of the initial Customer Agreement term (either in the form of cash payments during any applicable renewal period or a system purchase at the end of the initial term), for systems deployed as of the measurement date. Megawatts Deployed represents the aggregate megawatt production capacity of our solar energy systems, whether sold directly to customers or subject to executed Customer Agreements (i) for which we have confirmation that the systems are installed on the roof, subject to final inspection, (ii) in the case of certain system installations by our partners, for which we have accrued at least 80% of the expected project cost, or (iii) for multi-family and any other systems that have reached NTP, measured on the percentage of the project that has been completed based on expected project cost. Net Earning Assets represents Gross Earning Assets less both project level debt and pass-through financing obligations, as of the same measurement date. Because estimated cash distributions to our project equity financing partners are deducted from Gross Earning Assets, a proportional share of the corresponding project level debt is deducted from Net Earning Assets. NTP or Notice to Proceed refers to our internal confirmation that a solar energy system has met our installation requirements for size, equipment and design. Glossary of Vivint Solar Terms Installations represents the number of solar energy systems installed on customer premises. Megawatts (MWs) represents the DC nameplate megawatt production capacity. MW Installed represents the aggregate megawatt nameplate capacity of solar energy systems for which panels, inverters, and mounting and racking hardware have been installed on customer premises in the period. Estimated Gross Retained Value represents the net cash flows, discounted at 6%, that Vivint Solar expects to receive from customers pursuant to long-term customer contracts plus the value of contracted SRECs net of estimated cash distributions to fund investors, debt associated with forward flow facilities, and estimated operating expenses for systems installed as of the measurement date. For purposes of the calculation, Vivint Solar aggregates the estimated retained value from the solar energy systems during the typical 20 to 25-year term of Vivint Solar’s contracts, which Vivint Solar refers to as estimated retained value under energy contracts, and the estimated retained value associated with an assumed 5 to 10-year renewal term following the expiration of the initial contract term, which Vivint Solar refers to as estimated retained value of renewal. To calculate estimated retained value of renewal, Vivint Solar assumes all contracts are renewed at 90% of the contractual price in effect at the expiration of the initial term.
