Doesn't look like they have any other choice. After both Ukrainian suppliers were bombed out of business, the resulting shortage drove up neon prices by eye-watering 5000%. And considering that Ingas was based in Mariupol, a city that was utterly demolished by Russian shelling, I doubt they'll be able to resume production any time soon–even long after the city is liberated.
EDIT: no politics, I know. Everything I said is factual, relevant, and objective.
Thing is while Odessa and Mariupol have sustained attacks, Russia would not want to target non-military industrial factories. First due to international law and second because those factories would be the war prize if you get to control the region as a way to make money to rebuild. Sure the destruction will make those factories inoperable but to due to destruction of facilities but due to infrastructure (powering them for production) and lack of workers (because of evacuations).
Speaking hypothetically, of course, you would destroy what you cannot realistically take and hold. That deprives your adversary of industrial capacity and economic revenue, plus there's the impact on your adversary's morale.
