AMENDMENT NO. 1


EXPLANATORY NOTE


Hannon Armstrong Sustainable Infrastructure Capital, Inc. (the “Company”, “we,” “our,” or “us”) is filing this amendment (the “Form 10-K/A”) to our Annual Report on Form 10-K for the year ended December 31, 2017, originally filed with the Securities and Exchange Commission (“SEC”) on February 23, 2018 (the “Original Form 10-K”), solely for the purpose of complying with Regulation S-X, Rule 3-09. Rule 3-09 requires that Form 10-K contain separate financial statements for unconsolidated subsidiaries and investees accounted for by the equity method when such entities are individually significant.


We have determined that our equity method investments in MM Solar Parent LLC ("MM Solar") and Helix Fund I LLC ("Helix"), which are not consolidated in our financial statements, were significant under the income test of Rule 3-09 in relationship to our financial results for the year ended December 31, 2017. Since MM Solar’s and Helix's 2017 financial statements were not available until after the date of the filing of our Original Form 10-K, Rule 3-09 provides that the financial statements may be filed as an amendment to our Original Form 10-K within 90 days after the end of our fiscal year ended December 31, 2017.


Therefore, this Form 10-K/A amends Item 15 of our Original Form 10-K filed on February 23, 2018 to include the following Exhibits:
