AI Insight: OGS Financial Trends

ONE Gas Q1 2026 net income hit $129M — matching its best quarterly result in the dataset — while debt stabilized near $2.87B after a sharp H2 2025 surge.

• Net income recovered to $129M in Q1 2026, matching Q2 2024's $127M peak after troughing at $26M in Q3 2025.

• Operating income rebounded to $190M in Q1 2026 from a low of $65M in Q3 2025, reflecting typical seasonal gas-utility demand patterns.

• Equity grew steadily from $2,813M in Q3 2024 to $3,526M in Q1 2026, strengthening the balance sheet over six quarters.

• Total debt jumped from $2,414M in Q4 2024 to $2,885M in Q3 2025 — a $471M increase in two quarters — before plateauing near $2,871M in Q1 2026.

⚠ Operating cash flow collapsed to $43M in Q4 2025 from $277M in Q1 2025 — the weakest reading in the dataset — warranting close monitoring.

⚠ Debt-to-equity ratio rose to roughly 0.81x in Q3–Q4 2025 from 0.78x in Q4 2024; any further debt issuance could pressure leverage metrics.

⚠ Whether the Q1 2026 operating cash flow recovery to $176M is sustained through Q2–Q3 2026 will signal if the Q4 2025 cash trough was seasonal or structural.

AI Insight: OGS Ratio Trends

Return metrics have eroded materially over the past year, with ROIC sliding from 17.3% in Q2 2024 to 11.8% in Q1 2026.

• ROIC fell from 17.3% in Q2 2024 to 11.8% in Q1 2026, a 550bp decline over five quarters.

• ROE dropped from 17.9% in Q2 2024 to 14.6% in Q1 2026, with a trough of 3.3% in Q3 2025.

• D/E ratio rose from 0.75 in Q1 2025 to 0.91 in Q3 2025, partially retreating to 0.81 in Q1 2026.

• Q1 2026 ROE of 14.6% and ROA of 5.8% represent seasonal recovery, consistent with Q1 2025 seasonal strength.

⚠ TTM ROIC of 7.3% versus Q2 2024's 17.3% signals sustained full-year return compression, not just seasonal noise.

⚠ D/E spiked to 0.91 in Q3 2025 — highest in the dataset — monitor whether leverage stabilizes below 0.85.

⚠ Mid-year quarters (Q2–Q3) show consistently weak returns; watch whether Q2 2026 trough deepens further.
