Genmab Revises Financial Guidance


Summary:  Genmab has revised its 2009 financial guidance.                       

Copenhagen, Denmark; August 17, 2009 - Genmab A/S (OMX: GEN) announced today it 
is revising its 2009 financial guidance.  We now expect our 2009 revenue to be  
approximately DKK 750 million compared to the previous estimate of DKK 1.2      
billion. The reduction in revenue is primarily due to the exclusion of a        
milestone payment under the Arzerra(TM) (ofatumumab) collaboration with         
GlaxoSmithKline.                                                                

With a continued focus on cost control we now anticipate that our operating     
expenses will be approximately DKK 1.4 billion, DKK 200 million below our       
previous guidance of DKK 1.6 billion.  This will result in a revised operating  
loss of approximately DKK 650 million, as compared to our previous guidance of  
DKK 400 million.                                                                

We now expect the cash burn for 2009 to be approximately DKK 700 million        
compared to previous guidance of DKK 500 million. Therefore we project a cash   
balance at the end of the year of approximately DKK 1,050 million, DKK 200      
million below our previous guidance.                                            

2009 Guidance

*Cash, cash equivalents and marketable securities                               

The estimates above are subject to change due to numerous factors, including the
timing and variation of development activities, related income and costs and    
fluctuations in the value of our marketable securities 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 June 30, 2009 of USD 1.00 = DKK 5.2689.
