Both Kodak Alaris Holdings Ltd. and Harman Technology Ltd. are UK private companies. As such, they are required to make public their financial statements.
In some cases they are easy to access directly, in other cases, they can be accessed through reporting services.
Here are some of the results of my research into the most recent (December 31, 2016) statements
According to their financial statements, in the year ending December 31, 2016 Kodak Alaris had gross revenues of approximately 660 million British Pounds. About one-third of that is from what we would consider to be the film imaging business. That third is divided between Colour Paper (65%), Photo Chemicals (8%) and Film (14%).
About a third of Kodak Alaris' revenue from their Photo Kiosk business, while the remaining revenue comes from their information management businesses.
According to their financial statements, in the year ending December 31, 2016 Harman Technology Ltd. had total gross revenues of approximately 18.8 million British Pounds.
In total, and based on revenues, Kodak Alaris is approximately 30 times the size of Harman.
Speaking strictly about Kodak Alaris' film imaging division, that division alone is approximately 12 times the size of Harman. If you add on the division that deals with Kodak Alaris' Film Kiosk business, those two divisions together are more than 20 times the size of Harman.
Kodak Alaris has a really big stake in the film photography business.
