You need to quote the string with the & (and also %) in it.

Either add some macro quoting or add some real quotes.

data _null_;
  call symputX("test",'Events and T&E');
run;
%put &=test;
%let test=%superq(test);
%put &=test;

data _null_;
  call symputX("test",'''Events and T&E''');
run;
%put &=test;

401   data _null_;
402     call symputX("test",'Events and T&E');
403   run;

408   data _null_;

since your macro variable contains macro resolve symbole '&' ,if you want print it you need mask it firstly by macro mask function :

data _null_;
call symput("test",'Events and T&E');
run;
%put %superq(test);
