EXPLANATORY NOTE

Continental Resources, Inc. (we or our) is filing this Amendment No. 1 (this Amendment) to our
Form 10-K for the year ended December 31, 2009 originally filed with the Securities and Exchange Commission on February 26, 2010 (the Original 10-K Filing) solely for the purpose of filing a revised report of our third-party
petroleum engineering firm. The report of Ryder Scott Company, L.P. was filed as Exhibit 99.1 to the Original 10-K Filing. The report included a statement limiting the use of the report to Continental Resources, Inc. The report appearing in this
Form 10-K/A reflects the removal of any such limitation as well as adding other disclosure enhancements. In addition to the revised report being filed as Exhibit 99.1, we are including in this Amendment the consent of Ryder Scott Company, L.P. in
Exhibit 23.2 and certifications of our principal executive officer and principal financial officer in Exhibit 31.1 and 31.2.

Except as described above, this Amendment does not modify or update the disclosures presented in, or exhibits to, the Original 10-K
Filing in any way. Those sections of the Original 10-K Filing that are unaffected by this Amendment are not included herein. This Amendment continues to speak as of the date of the Original 10-K Filing. This Amendment has no impact on the
Companys previously reported audited financial statements and notes thereto as of December 31, 2009. Furthermore, this Amendment does not reflect events occurring after the filing of the Original 10-K Filing. Accordingly, this Amendment
should be read in conjunction with the Original 10-K Filing, as well as the Companys other filings made with the SEC pursuant to Section 13(a) or 15(d) of the Exchange Act subsequent to the filing of the Original 10-K Filing.
