The forward P/E of 23.8x and EV/EBITDA of 17.0x sit well above the peer group, suggesting investors are paying for CACI's intelligence community exposure and potential margin expansion. However, the PEG of 4.85 is elevated, indicating that the current growth rate may already be reflected in the price. If the 2026Q4 gross margin spike to 33.7% proves non-recurring, the valuation could compress toward the sector average.

Excluding the anomalous quarter, gross and operating margins have converged near 9%, reflecting a cost-plus-heavy contract portfolio with limited operating leverage. The 5.8% net margin in 2026Q4 is below the 6.9% reported in 2025Q4, indicating that revenue growth is not translating proportionally to bottom-line gains. Investors should monitor whether the company can sustain any margin expansion through fixed-price technology contracts, as labor cost inflation remains a persistent threat.

The recent $2.6B acquisition lifted total assets 73% YoY, but ROIC remained flat, suggesting the acquired assets are not yet contributing proportionally to operating income. ROE improved to 12.8% on a TTM basis, but this is partly driven by higher leverage (D/E of 1.20) rather than operational efficiency. If the buy-and-build strategy does not yield margin expansion, the company risks value destruction despite top-line momentum.

The cash conversion cycle widened from 36 days to 45 days over the same period, reflecting the working capital intensity of rapid revenue expansion. Asset turnover declined from 0.30 to 0.23, suggesting that the recent acquisition has not yet been integrated efficiently. The 2026Q4 FCF margin of 28.8% is a positive outlier, but the historical average near 6% indicates that cash generation remains lumpy and timing-dependent.

The D/EBITDA ratio of 15.2x is elevated relative to peers, and the sharp decline in interest coverage suggests that the recent acquisition was largely debt-funded. Although the company's cash flow generation is strong, the thin liquidity buffer of $191.8M against $5.3B in debt leaves limited room for additional leverage without refinancing risk. Investors should monitor whether the acquired assets generate sufficient EBITDA to restore coverage ratios to historical levels.

The quick ratio of 1.48 indicates that receivables are the primary liquid asset, which is typical for government contractors but exposes the company to payment delays during budget disruptions. The low cash balance suggests that future acquisitions would require additional debt or equity issuance, potentially straining the balance sheet further. Under a prolonged government shutdown scenario, the company's ability to meet near-term obligations could be tested, though the current ratio provides some cushion.

While CACI's ROE of 12.8% lags SAIC's 27.2% and Leidos' 26.4%, its revenue growth of 12.6% YoY outpaces the group, justifying some premium. However, the company's ROIC of 2.1% is well below Leidos' 17.1% and BAH's 18.6%, indicating that CACI's capital deployment is less efficient. The valuation gap may narrow if the market begins to question the sustainability of the 2026Q4 margin spike or if government budget pressures intensify.
