AI Insight: CTM Ratio Trends

Castellum's profitability briefly turned positive in Q3 2025 but reversed sharply in Q4 2025, leaving all returns still negative and recovery fragile.

• Operating margin improved dramatically from -15.7% in Q4 2024 to a positive 3.0% in Q3 2025 — the only profitable quarter in the dataset.

• Q4 2025 saw a sharp reversal: operating margin collapsed to -11.1% and ROIC fell to -15.6% from +4.9% the prior quarter.

• ROE improved significantly from -61.2% in Q2 2024 to -3.9% in Q1 2026, signaling a broad but incomplete multi-quarter recovery.

• D/E declined from 0.72 in Q2 2024 to 0.40 in Q4 2024 before data gaps emerged, suggesting some deleveraging progress.

⚠ Q4 2025 profitability collapse — ROIC dropped from +4.9% to -15.6% in one quarter — raises questions about earnings sustainability.

⚠ D/E data absent from Q1 2025 onward; leverage trajectory is unverifiable despite its prior improvement to 0.40.

⚠ TTM operating margin of -3.6% reflects Q4 2025 drag; whether Q1 2026's -4.9% trend stabilizes or worsens is critical to watch.
