2-year relative performance

At-a-glance comparison

Business model and revenue mix

SMCI Holdings, Inc. operates in Drug Manufacturers (Healthcare), while IONQ Holdings, Inc. sits in Internet Content & Information (Communication Services). The two operate in different sectors, so cyclicality and end-market exposure differ — factor that into any portfolio overlap. SMCI carries a beta of 1.65 versus 1.75 for IONQ, meaning IONQ has historically been the more volatile of the two.

Valuation

On valuation, IONQ is the cheaper stock. SMCI trades on a forward P/E of n/a and EV/EBITDA of 15.52, against 15.88 and 15.3 for IONQ. Price-to-sales is 19.57 vs 1.79, and free-cash-flow yield is 0.6% vs 3.8%. 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

IONQ is the faster grower. SMCI has compounded revenue at -4.3% over three years with EPS growth of -5.6%, while IONQ has delivered 6.0% revenue and 7.1% 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, IONQ is stronger. SMCI posts a -13.0% operating margin, -18.3% return on equity and -5.1% return on invested capital. IONQ posts 42.7%, 47.4% and 26.6% 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

SMCI has the safer balance sheet. SMCI carries net-debt/EBITDA of -0.86x with a current ratio of 2.88, versus 3.97x and 1.39 for IONQ. Lower leverage gives a company more room to invest through a downturn and reduces the risk of dilution or distress.

Over the past year SMCI returned -1.4% against -13.4% for IONQ; on a three-year annualised basis it is 0.8% vs -6.7%. SMCI yields 3.2% and IONQ yields 3.3%. Past performance never guarantees future results, but the multi-year track record shows how the market has rewarded each business so far.
