Revenue growth has decelerated from triple-digit post-merger spikes to -2.0% in 2026Q3, while gross margin volatility (ranging from 5.0% in 2024Q4 to 13.0% in 2026Q3) masks a structural ceiling near 7-8%, though operating margin improved to 5.6% in 2026Q3 on lower SG&A.

Revenue headwinds and integration risks
Metrics are mathematically derived from official filings.
Revenue Momentum Fades Post-Merger
Revenue growth has decelerated sharply from triple-digit post-merger spikes to negative 2.0% in 2026Q3, according to reported figures, suggesting the integration-driven surge is fading and organic demand may be softening.
The 71.59% year-over-year growth in 2025Q3 was largely a function of the Jacobs acquisition, but the subsequent quarters show a clear deceleration: 2025Q4 fell 7.5% and 2026Q1 fell 5.2%, with 2026Q3 at -2.0%. This pattern suggests the merger's revenue boost is fully lapped, and the underlying business may be facing contract timing delays or re-scoping, as hinted by management's commentary on near-term dynamics. Investors should monitor order intake and backlog conversion to assess whether this is a temporary dip or a structural slowdown.
Gross Margin Volatility Masks Structural Ceiling
Gross margin swung from 5.0% in 2024Q4 to 13.0% in 2026Q3, per financial statements, but the average remains near 7-8%, reflecting a cost-plus-heavy model with limited pricing power.
The 13.0% gross margin in 2026Q3 is an outlier versus the 7.0-7.5% range seen in most quarters, likely due to a favorable contract mix or one-time adjustments. The structurally low gross margin, compared to peers like Leidos at 17.7% and CACI at 33.2%, indicates a heavy reliance on pass-through costs and cost-plus contracts. Without a shift toward fixed-price or higher-margin cyber/intelligence work, sustained margin expansion appears constrained.
Operating Leverage Emerges in 2026Q3
Operating income jumped to $196M in 2026Q3 from $127M in 2026Q2, despite flat revenue, as SG&A fell to 3.5% of revenue, per reported data, indicating improved overhead efficiency.
The 54% sequential increase in operating income on essentially flat revenue suggests meaningful operating leverage, driven by a 13.0% gross margin and disciplined SG&A. However, this is a single quarter and may not be sustainable if the revenue decline persists. The SG&A line has been relatively stable around $120-150M, but the 2026Q3 ratio of 3.5% is the lowest in the series, implying management is controlling costs effectively. If revenue continues to contract, this leverage could reverse.
Net Income Volatility Signals One-Time Items
Net income swung from a -$272M loss in 2024Q4 to a $210M profit in 2026Q3, per income statement data, with EPS of $0.27, suggesting significant non-recurring charges and adjustments.
The 2024Q4 loss of -$272M likely includes merger-related charges and amortization of intangibles, while the 2026Q3 profit of $210M may benefit from tax benefits or one-time gains. The low SBC of $8M is not a major drag, but the wide swings in net margin (from -6.4% to 6.0%) indicate that reported earnings are not yet a clean reflection of underlying operations. Investors should adjust for these items to gauge steady-state profitability.
COGS Dominates as Labor Costs Bite
COGS consistently consumes over 87% of revenue, with gross margins averaging 7-8%, per financial data, highlighting the high-variable-cost structure and sensitivity to wage inflation.
The cost structure is heavily weighted toward skilled labor and pass-through expenses, leaving little room for error. The 2026Q3 gross margin of 13.0% is an anomaly; the typical 7% level means that even a 1% increase in labor costs could compress margins significantly. Management's expense discipline is evident in SG&A, but the primary cost driver remains COGS, which is difficult to control in a cost-plus environment. Wage inflation for cleared engineers and cyber professionals is a persistent risk.
2024Q4 Marks Transformational Inflection
The Jacobs acquisition in late 2024 caused revenue to jump from $1.4B to $4.2B in 2024Q4, per reported figures, but also triggered a -$272M net loss, marking a pivotal turning point.
The 2024Q4 quarter was the inflection point: revenue tripled sequentially due to the merger, but the massive loss reflects integration costs and purchase accounting adjustments. Since then, the company has stabilized, with net income turning positive in 2025Q1 and improving to $210M by 2026Q3. The lasting impact is a much larger revenue base but a thinner margin profile, as the combined entity operates with lower margins than the pre-merger standalone business. The success of the integration will determine whether this inflection leads to long-term value creation.
Margin Compression and Revenue Decline Risks
Despite the 2026Q3 beat, revenue is declining and gross margins remain volatile, per financial data, suggesting the profit improvement may be temporary and not indicative of durable growth.
Short-sellers would highlight that the 13.0% gross margin in 2026Q3 is unsustainable, as it is nearly double the historical average, and that revenue has declined for three consecutive quarters. The company's thin net margin of 6.0% in 2026Q3 could quickly erode if revenue continues to fall or if integration issues cause cost overruns. Additionally, the raised guidance for Adjusted EBITDA and EPS, despite a softer revenue outlook, may rely on cost cuts that are not repeatable. Investors should question whether the underlying business can generate organic growth and maintain margins in a competitive government services market.
