Is Newsela profitable?

I've been reading about Newsela, and I'm curious about their financial status. I understand they're a company that specializes in personalized reading materials for students, but what about their profitability? Are they turning a profit, or are they still in the red? I'm interested in knowing if they have a sustainable business model that can support their growth and expansion in the future. I'd appreciate any insights you can provide on this topic.
