When used at the beginning of a sentence, the adverb
尚（なお） ‘furthermore’ will often carry the meaning of ‘in addition’, ‘furthermore’, ‘even more’, or ‘moreover’. This use is regularly seen after the previous sentence or clause has expressed some base fact or situation that the second sentence will then add to. Especially when the information expressed in the (B) part of the sentence is surprising or shocking in some way.
This structure will almost always appear without the kanji being used.

As
尚（なお） is a formal grammar structure, it will most frequently appear in letters, posters, commercials and other similar material.
Fun-fact - In all of its uses, なお simply indicates that taking the previous information of (A) into account, although (B) may not be expected, it is in fact true. This can be used either positively or negatively, and just highlights (B) as exceeding expectations.
