Across Box (BOX), SentinelOne (S), ACI Worldwide (ACIW), Box (BOX) attracts more attention as the best risk/reward idea right now, with Worldwide (ACIW) second and SentinelOne as the speculative growth play. (All fundamentals below are from the Stocks2Buy Fundamentals analysis app, plus recent company reports.)

Key findings:

SentinelOne

Fastest top-line, but weakest fundamentals. Revenue is growing >20% with ARR around $1B and ~75–79% gross margins. However, it still has negative ROA/ROE (≈-18% / -27%), a tiny 0.4% FCF yield and EV/FCF above 200x, meaning the market already prices in a lot of future success while cash generation is only just turning positive. It’s a high-upside cyber/AI name, but clearly high risk.

Box

Slower growth, but a cash machine. It posts 79% gross margins, ROA ~13.7%, ROIC ~21.3%, and FCF yield ~7.4% with EV/FCF ~12x, plus consistent revenue growth in the mid–single digits and expanding non-GAAP operating margins near 28%.

Values extracted using the Stocks2Buy app

Fundamentals look excellent; the catch is valuation versus intrinsic value: the Stocks2Buy DCF around $18 vs. price ~$29–30implies the stock may be ~40% over fair value, so a lot of that quality is already priced in.

ACI Worldwide

Balanced growth + value. ACIW grows revenue high-single digits with recurring revenue up ~10–13%, and runs with ROE ~17.8%, ROIC ~11.4%, FCF yield ~6.4% and EV/FCF ~18x, all while de-levering its balance sheet.

Values extracted using the Stocks2Buy app

The Stocks2Buy DCF fair value (~$59 vs. price ~$47) and other DCF work suggest 20–40% upside, while still owning a profitable, cash-generating payments infrastructure franchise tied to secular digital-payments growth.

Final observations

• If you rank purely by fundamental quality: Box > ACIW > SentinelOne.

• If you rank by value vs. price right now: ACI Worldwide comes out as the best investment idea today, Box looks like a great business but priced rich, and SentinelOne is a smaller, speculative position for aggressive growth capital rather than a core holding
