Add message to all products excluding one category

Hey all…

I would like to adapt this working script so that it still shows on every single product apart from 1 specific category.

Is that possible?

Thank you in advance…

add_action( ‘woocommerce_single_product_summary’, ‘custom_text’, 15 );
function custom_text() {
print ‘<p class=”custom_text”>If not otherwise stated, our normal delivery lead time is 3 – 5 working days.</p>’;
}
