             Gevo, Inc. : Gevo Wins Patent Suit in Delaware Court

Butamax admits Gevo does not infringe and trial not needed

ENGLEWOOD, Colo. - March 21, 2013 - Gevo, Inc. (NASDAQ: GEVO), announced today
that a judgment  of non-infringement will  be entered for  Gevo following  the 
acknowledgment by Butamax Advanced Biofuels  LLC (Butamax) that Gevo does  not 
infringe Butamax's asserted patents  under the Court's  construction of a  key 
claim term in Butamax's Patent Nos.  7,851,188 and 7,993,889. As a result  of 
this victory, a judgment of non-infringement  will be entered in Gevo's  favor 
and the trial scheduled for April 1^st will no longer take place.

"This is an outstanding victory for  Gevo," noted Brett Lund, EVP and  General 
Counsel for Gevo. "We  have consistently maintained that  we do not  infringe 
any Butamax  patents  and  Butamax's  concession  resoundingly  validates  our 

The judgment of non-infringement comes on  the heels of the Court's  important 
claim  construction  determination  which  held  that  Butamax's  Patent  Nos. 
7,851,188 and 7,993,889 require the use of an "NADPH-dependent" KARI. Butamax
conceded that it could not establish that Gevo's KARI is NADPH-dependent.

"Gevo continues to  demonstrate that  it does not  infringe Butamax's  patents 
because Gevo created an NADH-dependent  KARI enzyme that enables Gevo's  yeast 
strains to produce isobutanol at much greater efficiencies than strains  using 
the NADPH-dependent enzymes claimed by Butamax," said Lund. "We fully expect
Butamax will appeal to the Federal Circuit, but we are confident in the merits
of our case."

In addition to granting a judgment of non-infringement, the Court  invalidated 
Butamax's  patent  claims  for  the  deletion  of  PDC.  PDC  is  the  enzyme 
responsible  for  making  ethanol  and  its  deletion  is  required  for   the 
commercially viable  production of  isobutanol. Gevo's  patents covering  the 
deletion of PDC and the use of AFT  are set for trial in August of this  year, 
where Gevo is suing Butamax for patent infringement.

Gevo will host a conference call on Thursday, Mar. 21, 2013 at 11:30 a.m. EDT
(9:30 a.m. MDT) to discuss this significant win.
