How do I read company annual reports for basic stock analysis?

Hey everyone!

I've been trying to do more research before buying individual stocks instead of just following tips online. Everyone says to "read the annual report" but honestly, I'm pretty lost when I open these massive PDF files. There's so many numbers and sections!

Could anyone give me some tips on what parts I should focus on first? And maybe explain what key numbers or red flags to look out for?

Right now I basically just look at the revenue growth and maybe the P/E ratio, but I know there's probably way more important stuff I'm missing. Thank you!
