Intends to Request Hearing

SAN FRANCISCO, Jan. 20, 2015 -- CollabRx, Inc. (NASDAQ:CLRX) ("the Company") announced that it received a letter from the NASDAQ Listing Qualifications Staff indicating that, unless the Company timely requests a hearing before the NASDAQ Listing Qualifications Panel (the "Panel"), the Company's securities would be delisted from The NASDAQ Capital Market due to the Company's non-compliance with NASDAQ Listing Rule 5550(b)(1) (the "Rule").
