EXPLANATORY NOTE

This Amendment No. 1 to the Form 10-K (this Amendment) amends the Annual Report on Form 10-K of Nevro Corp. for the year ended
December 31, 2014 filed on March 18, 2015 (the Form 10-K) for the sole purpose of refiling Exhibit 10.22 (certain portions of which are omitted pursuant to a confidential treatment request filed with the SEC) and in connection
therewith, to amend the Exhibit Index to the 10-K. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Amendment also contains new certifications pursuant to Section 302 of the Sarbanes-Oxley Act of 2002, which
are attached hereto. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4, and 5 of the
certifications have been omitted.

No other changes have been made to the Form 10-K. This Amendment does not reflect events that may have occurred
subsequent to the original filing date, and does not modify or update in any way the disclosures made in the original Form 10-K.
