noun
Honorific term used in formal business writing and speech to refer to the recipient's company. Often paired with 御社 (おんしゃ) which is slightly less formal and more common in spoken business Japanese.

貴社のご発展をお祈り申し上げます。
I wish your company continued success.
貴社の製品に大変興味を持っております。

noun
your shrine
Rare honorific use when addressing a shrine in formal writing. In modern Japanese, 御社 (おんしゃ) is not used for shrines, so 貴社 can serve this specific function, though it is uncommon.
貴社の由緒ある祭礼に参加でき光栄です。
It is an honor to participate in your shrine's historic festival.
