I will let you shorten this -

Code:
gawk -F "|" 'FILENAME=="1.txt"{!a[$1]++;next}
                FILENAME=="2.txt"{if($1 in b)next  
                     else b[$1]=$2"|"$3;next}  
            FILENAME=="3.txt"{if($1 in d)next 
               else d[$1]=$2"|"$3;next}     
    END{for(i in a)print i,b[i],d[i]}' OFS="|" 1.txt 2.txt 3.txt
