Research Frontiers Inc (REFR): Operating Income

Annual figures by period end, from SEC filings.

Restated years: each year's figure is from the latest filing that reports it. The company later restated the years ended 2012-12-31, 2019-12-31 (for example after a spin-off or a discontinued operation), while the year before each was last reported on the old basis. Changes across those points are marked n/c (not comparable), and growth rates are not computed across them.
