Cliff Risk Date depends on the country and is defined as the date in which the project passes the last of the high-risk stages (usually: Environmental approval, Interconnection agreement, Power Purchase Agreement). All late stage projects have secured or are reasonably assured to secure a PPA, or FiT. Some late-stage projects may not reach completion due to failure to secure other permits or changes in market conditions among other risk factors. Investors are advised to review a more detailed discussion of the risks factors contained in the company’s annual report on Form-20F.  Early stage pipeline includes only those projects that have been approved by our internal Investment Committee or projects that are expected to be brought to the Investment Committee in the next two quarters Source: Canadian Solar Inc. 32 Canadian Solar total pipeline exceeds 13 GWp, providing visibility into demand over the next several years.

Energy Business Summary Financials Key highlights Lower revenues in Q3 was mainly driven by the delayed closing of project sales in Japan, which are expected to be completed in Q4 2019 and Q1 2020. Q3 projects sold included the sale of the 266 MWp Rambler project in the US and the sale of 80% interest in the 172 MWp Lavras project in Brazil, both sales were pre-construction. Despite lower revenues, Q3 gross margin expanded due to greater share of NTP sales which has a higher gross margin % contribution.

GAAP to Non-GAAP Reconciliation To supplement financial disclosures presented in accordance with GAAP, the Company uses non-GAAP measures which are adjusted from the most comparable GAAP measures for certain items as described herein. The Company presents non-GAAP values for EBITDA so that readers can better understand the underlying operating performance of the business, excluding the effect of non-cash costs such as depreciation, amortization and impairments. The non-GAAP numbers are not measures of financial performance under U.S. GAAP, and should not be considered in isolation or as an alternative to other measures determined in accordance with GAAP. These non-GAAP measures may differ from non-GAAP measures used by other companies, and therefore their comparability may be limited.
