In 2013 SAS reported revenues of $3.02B. In 2023, SAS reported revenues of "over $3B" (https://en.wikipedia.org/wiki/SAS_Institute, https://www.sas.com/content/dam/SAS/documents/corporate-collateral/annual-report/company-overview-annual-report.pdf).
$3B in 2023 is worth almost $4B in 2013 dollars. So, adjusted for inflation, SAS claims that its revenues declined almost 25% over 10 years (https://www.bls.gov/data/inflation_calculator.htm).
Suppose that in 2013 SAS made a 10% profit. With an average 2.5% annual decline in revenues, by 2018, that profit could have dropped to zero. So it's quite believable that SAS now requires buyouts and layoffs to maintain profitability. Since 2018, that's exactly what we've seen.
The majority owner has consistently said that SAS is worth $15-20B. Even judging from published numbers, Broadcom may have reasonably concluded that SAS is worth no more than $10B. That's one possible reason the deal fell through.
Of course, SAS will put the most positive spin on its numbers. Every corporation does that. But there's no reason to believe they're lying, because the published numbers explain everything we've seen.
