Genmab Revises Financial Guidance


Summary:  Genmab has revised its 2009 financial guidance and provided           
information on the financial impact of the reorganization plan announced today. 

Copenhagen, Denmark; November 5, 2009 - Genmab A/S (OMX: GEN) announced today it
is revising its 2009 financial guidance.                                        

Genmab announced a reorganization plan in a separate stock exchange release     
(no.41/2009) including a contemplated reduction in headcount of approximately   
300 positions and decision to sell its manufacturing facility in Brooklyn Park, 
Minnesota, USA. As a result, Genmab is revising its 2009 financial guidance.    

At certain Genmab locations the reduction in headcount and severance packages   
offered are subject to consultation discussions and therefore the estimates     
included in this release are subject to change. However, we estimate that the   
cash cost of the reduction in workforce including severance, retention payments 
and other costs to be approximately DKK 105 million. We currently estimate a    
cash impact of DKK 38 million in 2009 and DKK 67 million in 2010.               

We estimate that the re-organization charges above will impact the 2009 income  
statement by approximately DKK 80 million, including non-cash warrant expenses  
of approximately DKK 22 million.                                                

We will also recognize an impairment charge in the fourth quarter of 2009       
related to the proposed sale of the Brooklyn Park facility. We have estimated   
the fair value of the facility to be approximately USD 150 million less sales   
related costs of approximately USD 5 million, resulting in a fair value less    
cost to sell of approximately USD 145 million (DKK 737 million as of November 3,
2009), which resulted in a non-cash impairment charge of approximately USD 83   
million (DKK 420 million as of November 3, 2009). The fair value less cost to   
sell and impairment is based on the best information available and may be       
subject to change.                                                              

The Brooklyn Park facility will be classified as held for sale and will         
therefore be presented as a discontinued operation in the fourth quarter of     
2009. This change in presentation is not yet reflected in the revised guidance  
below. The facility will be kept in maintenance mode pending the sale, incurring
an estimated annualized expense of USD 10 million (DKK 50 million).             

The annualized impact of the reorganization is estimated to yield savings of    
approximately DKK 300 million, including non-cash items of approximately DKK 60 
million.                                                                        

This revised guidance also includes some other changes to the previously issued 
2009 guidance. We expect our 2009 revenue to be approximately DKK 640 million   
compared to the previous estimate of DKK 750 million. The reduction in revenue  
is primarily due to the delay of a milestone payment to 2010 that was originally
expected in 2009 under the Arzerra(TM) (ofatumumab) collaboration with          
GlaxoSmithKline.                                                                

We anticipate that our operating expenses will be approximately DKK 1.3 billion,
DKK 100 million below our previous guidance of DKK 1.4 billion due a continued  
focus on cost control.  This will result in a revised operating loss of         
approximately DKK 660 million before the reorganization charges, as compared to 
our previous guidance of DKK 650 million.                                       

Including the impact of all of the items discussed above we estimate a revised  
operating loss of approximately DKK 1,160 million, as compared to our previous  
guidance of DKK 650 million.                                                    

After reflecting the impact of the reorganization we expect the cash burn for   
2009 to be approximately DKK 700 million which is at the same level as our      
previous guidance. Therefore, Genmab still projects a cash balance at the end of
the year of approximately DKK 1.1 billion.                                      

We therefore anticipate that the guidance after reflecting the impact of the    
reorganization and other items discussed above to be as follows:

In addition to factors already mentioned the estimates above are subject to     
change due to numerous reasons, including the timing and variation of           
development activities, related income and costs and fluctuations in the value  
of our marketable securities, fair value less cost to sell related to our       
manufacturing facility and currency exchange rates. The financial guidance also 
assumes that no further significant agreements are entered into during 2009 that
could materially affect the results.                                            

Conversion of our 2009 guidance has been made using the Danish Central Bank     
closing spot rate on September 30, 2009 of USD 1.00 = DKK 5.0839.
