If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

	(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

 

PART III — NARRATIVE

 

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

 

The former Chief Financial Officer of A123 Systems, Inc. (the “Registrant”) resigned in January of 2011, and, as a result, on an interim basis, the Registrant’s Vice President of Finance and Corporate Controller is also fulfilling the role as the interim Chief Financial Officer.  Additionally, the Registrant’s filing status changed as of December 31, 2010 from a non-accelerated filer to large accelerated filer, which accelerated the Registrant’s filing deadline.  Due to the executive-level personnel change and the filing status change, the Registrant could not file Form 10-K within the prescribed time period without unreasonable effort or expense.

 

In accordance with Rule 12b-25 of the Securities Exchange Act of 1934, the Registrant will file its Form 10-K no later than the fifteenth calendar day following the prescribed due date.
