Shareholders care about profitability of the firm. The shareholders that ask questions at annual meetings are generally small retail investor "super fans." They tend to be more interested in the company's content than the company's performance. The actual number of retail investors who are in this group is comparatively tiny. The vast majority of shareholders (including institutions, pensions, hedge funds) are very concerned with the profitability of The Walt Disney Company. That includes box office grosses.
The Walt Disney Company has more than ten studio releases due in 2025. Because of this diversification, Disney is well positioned to handle individual poor performing films. However, multiple movies underperforming in a year can absolutely impact overall profitability and performance. Each film does matter, but the impact is blunted by diversification.
@Disstevefan1 is presenting a reasonable strategy for dealing with the shifting media landscape. By reducing budgets, Disney can accept lower box office grosses while turning handsome profits. The only complication are audiences expectations. While audiences accept films that are less flashy? The other way to reduce budgets is to have projects more fleshed out when they are approved. That could reduce expensive reshoots, though that might hamper the creative team's ability to adjust to the film as it's realized. It's tricky business.
