So for 2022, they spent way more than they brought in, reduced their cash position and went further into debt. Yet, if you rely on retained earnings, you would never know this. Now look at Q123 where they had just under -9B in free cash flow and increased their debt ~33% to 50B in just the first three months of the year. Their retained earnings are gone, they've been tied up in assets that will have to actually start producing meaningful revenue sooner than later (meaning the next couple of years) or else you'll start to see that retained earnings evaporate rapidly.
And a lot of this big investment push they have been making is catching up from years of underinvestment. Partially because of years of being stuck on 10nm so they didn't have any new processes to invest in and partially because they felt they were dominating the industry and would rather use that money for buybacks (which increases share price and EPS helping exec bonuses and stock options!)
Since AMD became competitive and Apple told them 'see ya' Wall Street started punishing them for their dysfunction. Intel management realizes they are in a make or break moment for the company over the next couple years. The people trying to paint a false rosy picture of Intel's current position and results are either ignorant or knowingly lying. Intel's leadership knows they have to spend a lot to catch up on those years of underinvestment to outfit fabs for the new processes they've announced, so the high rate of cash burn is necessary.
If they are able to deliver on their promises they'll be fine. If they run into more issues like they had with 10nm they will be in serious trouble. They will still be able to borrow money to feed more cash into the furnaces but rates are higher today and Intel would no doubt have its credit downgraded further increasing borrowing cost. That leads to a kind of death spiral where companies borrow more and more money at higher and higher rates until they can't make the debt service payments and need to file for bankruptcy protection. I don't think it is likely this will happen - they'd need to be unable to deliver on their new processes at all rather than just be unable to meet their aggressive roadmap. But it is most definitely not outside the realm of possibility, regardless of what the rah-rah Intel folk here would like to believe.
