The "better buy" depends entirely on your goals: growth investors should weight revenue trajectory, value investors should weight P/E and PEG, and income investors should weight dividend yield and streak.

Over a 3-year CAGR, SONM leads at 2. 2% annualised revenue growth. Higher growth typically commands a higher valuation multiple — check whether the premium P/E or P/S is justified by the growth rate using the PEG ratio.

AT&T Inc.

(T) is the more profitable company, earning 17. 4% net margin versus -173. 3% for Smith Micro Software, Inc. — meaning it keeps 17. 4% of every revenue dollar as bottom-line profit.

09

Is SONM or SMSI or T or VZ better for a retirement portfolio?

For long-horizon retirement investors, AT&T Inc.

(T) is the stronger choice — it scores higher on the combination of lower volatility, dividend reliability, and long-term compounding (low volatility (β -0. 25), 4. 5% yield). Both have compounded well over 10 years (T: +41. 6%, SONM: -100. 0%), confirming both are viable long-term holds — but the lower-volatility option typically results in less emotional selling during corrections. Retirement portfolios generally favour predictability over maximum returns. Consult a financial advisor before making allocation decisions.

10
