Cisco Systems Inc. (NASDAQ:CSCO)

An analysis of the earnings trajectory reveals a period of growth followed by a cyclical contraction and a subsequent strong recovery. EBITDA peaked in July 2023 at 17,471 million US$ before experiencing a decline over the next two fiscal years, reaching a low of 15,504 million US$ by July 2025. This trend is mirrored across EBIT, EBT, and Net Income, suggesting a systemic impact on operational profitability during the middle of the analyzed period.

EBITDA Trend and Volatility

EBITDA exhibited a steady upward movement from 15,558 million US$ in July 2021 to 17,471 million US$ in July 2023. A subsequent contraction occurred, with values dropping to 15,747 million US$ in July 2024 and 15,504 million US$ in July 2025. A significant rebound is observed for July 2026, with EBITDA reaching a period high of 20,019 million US$, representing a substantial increase of approximately 29.1% over the previous year.

Operational Profitability and Non-Cash Expenses

The relationship between EBITDA and EBIT highlights the impact of depreciation and amortization. The spread between these two metrics widened notably in July 2024 and July 2025, indicating an increase in non-cash charges during the years when overall operational earnings were declining. Specifically, the gap reached its peak in July 2025 at 2,811 million US$, compared to a low of 1,726 million US$ in July 2023, which exerted additional downward pressure on EBIT.

Earnings Conversion and Net Income

Net income trends align closely with the EBITDA cycle, although the conversion from operational earnings to bottom-line profit remains subject to interest and tax obligations. The most significant absolute growth in net income is projected between July 2025 and July 2026, rising from 10,180 million US$ to 13,267 million US$. Despite the projected surge in EBITDA to 20,019 million US$ by July 2026, the conversion to net income remains constrained, reflecting the persistent impact of taxes and interest expenses on the final profitability.

An analysis of the valuation metrics reveals a period of initial volatility followed by a sharp expansion in the Enterprise Value to EBITDA (EV/EBITDA) multiple. After a contraction between 2021 and 2022, the valuation ratio entered a sustained upward trajectory, culminating in a peak in 2026.

Enterprise Value (EV) Dynamics

The Enterprise Value experienced a decline from US$ 234,167 million in 2021 to US$ 176,666 million in 2022. Following a period of moderate recovery and stabilization through 2024, a phase of aggressive growth occurred. Between July 2024 and July 2026, the EV increased from US$ 209,173 million to US$ 445,171 million, representing more than a doubling of the company's total market valuation within two years.

EBITDA Performance

Earnings before interest, tax, depreciation, and amortization remained relatively stable for the majority of the period. EBITDA grew from US$ 15,558 million in 2021 to a peak of US$ 17,471 million in 2023, before experiencing slight retractions in 2024 and 2025. A notable increase is observed in 2026, with EBITDA rising to US$ 20,019 million.

EV/EBITDA Ratio Interpretation

The EV/EBITDA ratio reached a minimum of 10.52 in 2022, indicating a period of valuation compression. From 2023 onward, the ratio climbed steadily to 12.16 and 13.28 in 2023 and 2024, respectively. A sharp acceleration in the multiple is evident in the final two years, rising to 18.03 in 2025 and peaking at 22.24 in 2026. This trajectory demonstrates that the increase in Enterprise Value significantly outpaced the growth in operational earnings, leading to a substantially higher valuation multiple by the end of the period.
