Amendment Description The sole purpose of this Amendment No. 1 (this “Amendment”) to MusclePharm Corporation’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2013, filed with the Securities and Exchange Commission on August 14, 2013 (the “Form 10-Q”), is to correct an error in the calculation of sales concentration by customer for the six months Ended June 30, 2012 in Note 2 of the Consolidated Financial Statements.  Specifically, Note 2, Subsection “Revenue Recognition” was revised to indicate that the percent of sales for the three largest customers for the three and six months ended June 30, 2013 was as follows: Three Months Ended June 30,   Customer 2013 2012 A 25 % 33 % B 11 % 8 % C 6 % 1 % Six Months Ended June 30, Customer 2013 2012 A 29 % 40 % B 11 % 11 % C 6 % 17 % The previously disclosed calculation for the three largest customers for the six months ended June 30, 2013 was 31%, 12%, and 6%, respectively. While customers A and B remained the same for the three months and six months ended basis, customer C changed for the three months ended June 30, 2012. The calculations are based on gross customer sales as a percent of gross sales for the applicable period. No other modifications or changes have been made to the Form 10-Q. This Amendment speaks as of the original filing date of the Form 10-Q, does not reflect events that may have occurred subsequent to the original filing date and does not modify or update in any way disclosures made in the original Form 10-Q.
