2-year relative performance

At-a-glance comparison

Business model and revenue mix

IONQ Holdings, Inc. operates in Internet Content & Information (Communication Services), while MU Holdings, Inc. sits in Software—Infrastructure (Technology). The two operate in different sectors, so cyclicality and end-market exposure differ — factor that into any portfolio overlap. IONQ carries a beta of 1.75 versus 1.76 for MU, meaning MU has historically been the more volatile of the two.

Valuation

On valuation, IONQ is the cheaper stock. IONQ trades on a forward P/E of 15.88 and EV/EBITDA of 15.3, against 29.96 and 32.42 for MU. Price-to-sales is 1.79 vs 4.11, and free-cash-flow yield is 3.8% vs 5.5%. A higher multiple is only justified if the company can sustain faster growth or wider margins, which is exactly what the next sections test.

Growth profile

MU is the faster grower. IONQ has compounded revenue at 6.0% over three years with EPS growth of 7.1%, while MU has delivered 20.5% revenue and 13.3% EPS growth. Growth like this is the single biggest driver of long-term returns, but it also tends to come with a richer valuation, so it must be weighed against the multiples above.

Profitability and quality

On profitability and quality, neither clearly is stronger. IONQ posts a 42.7% operating margin, 47.4% return on equity and 26.6% return on invested capital. MU posts 44.1%, 24.8% and 22.2% respectively. Return on invested capital above roughly 15% is a hallmark of a durable competitive advantage, so this metric deserves particular attention.

Balance-sheet risk

MU has the safer balance sheet. IONQ carries net-debt/EBITDA of 3.97x with a current ratio of 1.39, versus -0.74x and 1.58 for MU. Lower leverage gives a company more room to invest through a downturn and reduces the risk of dilution or distress.

Over the past year IONQ returned -13.4% against 50.4% for MU; on a three-year annualised basis it is -6.7% vs 27.0%. IONQ yields 3.3% and MU yields 0.2%. Past performance never guarantees future results, but the multi-year track record shows how the market has rewarded each business so far.
