Pro forma is a Latin term that means "for the sake of form," and it's commonly used to refer to financial statements that accountants create to highlight projected future earnings. Antonyms for pro forma could be genuine, authentic, real, substantive, or actual. These words suggest that there's something substantial, realistic, or based on actual performance, in contrast to something that is done merely to comply with regulations or expectations. Therefore, antonyms for pro forma can convey the opposite qualities, such as sincerity, truthfulness, or honesty, and imply that whatever they refer to is not just a paper exercise, but a genuine reflection of the underlying reality.
