Fun facts about AAON, INC.

Quirks, history, and lore behind AAON — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. industrials company · listed on Nasdaq · headquartered in Oklahoma · operates in the HVAC manufacturing sector.
2
The Numbers
A small-to-mid cap manufacturer with annual revenue in the low billions, boasting profit margins that make larger rivals look sloppy — consistently above 20% operating margin.
3
The History
Founded in 1987 by a group of former employees who spun out of a bigger HVAC company, it was essentially built by people who already knew the heating and cooling business inside out.
4
The Secret
Unlike most manufacturers, it does nearly everything in-house — fabricating its own parts rather than outsourcing — which is a big reason its margins stay unusually fat.
5
The Lore
Its customers are largely commercial and industrial buildings, not homeowners — think big rooftop units, not the box humming outside your bedroom window. It sells almost exclusively through independent representatives.
6
The Giveaway
Its ticker is practically a double-A roar — four letters, two of them the same vowel twice — and it makes commercial rooftop HVAC units out of Tulsa, Oklahoma.

AI Insight: AAON Financial Trends

AAON's revenue surged to a record $497M in Q1 2026, but net margins remain well below mid-2024 peaks despite sequential recovery.

• Revenue accelerated sharply, rising from $312M in Q2 2025 to $497M in Q1 2026 — a 59% climb in three quarters.

• Net income fell from $52–53M in Q2–Q3 2024 to $15M in Q2 2025, recovering only to $40M in Q1 2026 despite higher revenues.

• Operating cash flow turned sharply negative in Q1–Q2 2025 (-$9M, -$22M) before recovering to $34M in Q1 2026.

• Total debt was eliminated by Q2 2025, dropping from $16M to $0M — a modest but clean balance sheet improvement.

⚠ Net margin compressed from ~16.6% in Q2 2024 to ~8.0% in Q1 2026 despite record revenue — margin recovery is the key test.

⚠ Operating cash flow remains thin ($34M on $497M revenue) after two consecutive negative quarters; conversion needs to improve.

⚠ Revenue jump from $384M to $497M in one quarter warrants scrutiny — sustainability of this demand surge is unconfirmed.

AI Insight: AAON Ratio Trends

AAON's profitability has roughly halved from mid-2024 peaks, with operating margin settling near 11% after a sharp compression that troughed at 7.6% in Q2 2025.

• Operating margin collapsed from 21.4% in Q2 2024 to a trough of 7.6% in Q2 2025, a 13.8pp decline in three quarters.

• ROA followed the same path, falling from 20.7% in Q2 2024 to 4.4% in Q2 2025 before partially recovering to 8.9% in Q1 2026.

• Sequential improvement is visible: operating margin has risen from 7.6% in Q2 2025 to 11.5% in Q1 2026, a three-quarter recovery trend.

⚠ Margins remain well below Q2–Q3 2024 highs; sustained recovery back above 15% operating margin is unconfirmed and warrants monitoring.

⚠ Q2 2025 trough (7.6% OpMargin, 4.4% ROA) may signal structural cost pressure or mix shift — root cause clarity is key.
