ADTRAN Holdings, Inc. (ADTN) 10Y Growth Potential Analysis (2026)

Invetso Score: 4.8/10 — Balanced · Last Updated: 2026-08-01

Overall Score

Growth Durability

Revenue base remains modestly valued at 0.60x sales, but the company is still posting negative net income and weak operating profitability.

Gross margin is healthy at 38.5%, yet EBIT margin is only 1.7% and operating margin is slightly negative, limiting evidence of durable earnings expansion.

R&D intensity remains meaningful at 18.3% of revenue, supporting product investment but not yet translating into strong bottom-line growth.

Financial Strength

Liquidity is acceptable with a 1.79 current ratio and 1.19 quick ratio, giving the company room to operate.

Leverage is manageable but not low, with net debt to EBITDA at 1.41x and debt to capital at 65.2%.

Cash generation is positive, but quality is mixed given income quality of 0.32 and negative earnings yield.

Profitability Trend

Returns remain weak, with ROA at -2.3%, ROE at -18.8%, and ROIC near breakeven at -0.2%.

Interest coverage is negative at -0.07x, indicating operating earnings are not covering interest expense.

Net margin is still negative at -2.3%, showing the business has not yet converted gross profit into consistent net profit.

Cash Flow Resilience

Free cash flow remains positive, with a 8.4% FCF yield and 0.61 FCF-to-OCF conversion.

Operating cash flow covers capex comfortably, with capex only 38.8% of operating cash flow.

Cash conversion cycle is elevated at 89.5 days, reflecting working-capital drag despite decent payables support.

Valuation Support

Valuation is inexpensive on sales and cash flow, at 0.60x EV/sales and 12.0x price to free cash flow.

However, the negative earnings profile makes earnings-based multiples less informative and keeps valuation support from being stronger.

Book-based valuation is less compelling at 5.23x price to book given weak returns on capital.
