You could do something along these lines, replacing LETTERS with your 
company names:

df <- data.frame(SPEC1 = runif(26), SPEC2 = runif(26), COMPANY = LETTERS)

par(lab=c(10,10,7), las=1)
plot(df$SPEC1, df$SPEC2, type="n", xlab="Specification 1", 
ylab="Specification 2", ylim=c(0,1), xlim=c(0,1))
text(df$SPEC1, df$SPEC2, df$COMPANY)
axis(side=1, at = .5, tck=1, col="grey", lty=2)
axis(side=2, at = .5, tck=1, col="grey", lty=2)
