The companies
RBRKRubrik, Inc.
Why now
Software - Infrastructure · market cap $15.4b. Down 25% from 52-week high of $99.75 — deep drawdown territory. Revenue growing +46% — in hypergrowth territory. 26 sell-side analysts publish a mean 1-yr target of $95.23 (implying +27% upside).
Moat
Free cash flow runs well ahead of reported net income — non-cash charges (depreciation, intangible amortization) are holding down GAAP earnings while cash generation stays strong. Software economics — recurring revenue, embedded customer workflows, and high gross margin all compound the moat once a base account is won. Switching costs are the lever.
Risk
P/S 10.8x embeds aggressive forward growth — disappointing top-line guidance would compress the multiple hard. Net margin 4.2% is thin — operating leverage cuts both ways; input-cost inflation or pricing pressure hits the bottom line first. ROE -12% is below the long-run sustainable threshold of ~10% — capital efficiency would need to improve for the equity base to compound at the market rate.
TENBTenable Holdings, Inc.
Why now
Software - Infrastructure · market cap $3.9b. 20% off the 52-week high of $43.67. Revenue growing +11%, comfortably above the S&P median. PEG 0.99 — paying under fair value for the growth rate. 20 sell-side analysts rate this a Buy with a mean 1-yr target of $35.35 (implying +1% upside).
Moat
Software economics — recurring revenue, embedded customer workflows, and high gross margin all compound the moat once a base account is won. Switching costs are the lever.
Risk
D/E 2.11 is elevated — limits strategic flexibility and raises refinancing exposure if rates stay higher for longer. Currently unprofitable (margin -1.2%) — path to GAAP profitability is the core thesis risk. ROE -5% is below the long-run sustainable threshold of ~10% — capital efficiency would need to improve for the equity base to compound at the market rate.
