Look-through earnings include the profits that a company pays to its shareholders in the form of dividends and the retained earnings that the company uses to expand its operations. This concept was popularized by Warren Buffet to analyze the overall earnings-generating capabilities of the firm. The idea is that all of these profits have value to investors - the dividends provide an immediate benefit, while the retained earnings should increase the stock's value in the future.
