ABB’s audited FY2023 Form 20-F reports consolidated revenues of $32,235 million and operational EBITA of $5,428 million, implying an operational EBITA margin of 16.8%. Source: ABB Ltd, Form 20-F, fiscal year ended 2023-12-31, accession no. 0001091987-24-000006, filed 2024-02-22, accessed 2026-04-26, URL sec.gov .

Fresher, unaudited full-year 2024 figures come from ABB’s January 2025 result disclosure: revenues of $32,850 million, operational EBITA of $5,961 million, operational EBITA margin of 18.1%, net income of $3,935 million, and basic EPS of $2.13. Orders for FY2024 were $33,746 million. Source: ABB Ltd, Form 6-K, filed 2025-01-30, accession no. 0001091987-25-000004, accessed 2026-04-26, URL sec.gov . These are company-reported but unaudited interim figures; the audited annual filing remains the highest-quality anchor for the segmented model below.

ABB’s reportable segments are: Electrification, Motion, Process Automation, and Robotics & Discrete Automation. The table below uses the audited FY2023 segment note.

\*Share denominator is the sum of the four reported total segment revenues before corporate/eliminations. Because segment total revenue includes intersegment revenue, the segment sum slightly exceeds consolidated FY2023 revenue of $32,235 million; the difference is approximately $174 million.

The business is therefore predominantly an electrical-distribution and electrification company: Electrification is roughly half of segment revenue and carries the highest margin of the four segments. Robotics & Discrete Automation is the smallest segment and the lowest-margin segment, which matters for the bear case because it is the most exposed to discrete manufacturing and automotive capital expenditure.

Gross margin: ABB’s management disclosure emphasizes operational EBITA margin rather than gross margin as the lead profit metric. The audited income statement contains a cost-of-sales line, but I did not pull that exact line item into the working set; I therefore mark the precise audited gross margin as needs primary source validation rather than use a potentially inaccurate figure.

ABB monetizes through:

• Hardware product sales: low- and medium-voltage switchgear, circuit breakers, drives, motors, generators, robots, instrumentation, control systems, chargers, and related equipment.
• Project and system sales: engineered electrical distribution, process automation, marine, mining, and propulsion systems.
• Aftermarket and service revenue: spare parts, maintenance, retrofits, upgrades, repairs, and long-term service agreements.
• Software / digital subscriptions: ABB Ability portfolio, asset monitoring, energy management, process optimization, and condition-based maintenance.

The paying counterparties are asset owners and operators — utilities, industrial companies, infrastructure operators, marine/offshore operators, transit authorities, building owners, and data-center developers — as well as channel partners such as electrical contractors, panel builders, distributors, and system integrators.

From the FY2024 6-K:

\[

\text{Book-to-bill} = \frac{\text{orders}}{\text{revenues}} = \frac{\$33,746\text{m}}{\$32,850\text{m}} = 1.027

\]

This indicates ABB entered 2025 with an order intake slightly above revenue, a positive signal for near-term revenue conversion, assuming orders convert at normal lead times and are not cancelled. Source: ABB Ltd, Form 6-K, filed 2025-01-30, accession no. 0001091987-25-000004, accessed 2026-04-26, URL sec.gov .

Use ABB’s largest and most profitable segment, Electrification, to show the profit drop-through on incremental revenue.

\[

\text{Incremental EBITA} = \text{Segment revenue} \times \text{growth assumption} \times \text{incremental EBITA margin}

\]

Inputs:

\[

\$14,693\text{m} \times 5\% \times 23.0\% = \$169.0\text{m}

\]

A 5% increase in Electrification revenue, all else equal and using a 23.0% incremental operating EBITA margin, would generate approximately $169 million of additional operational EBITA.

Sensitivity:

This is a “unit economics” calculation only for the profit contribution of the segment; it assumes the incremental margin equals the base-year margin and assumes no other cost step-change. The assumption is deliberately transparent.

Parameter table:

This calculation is sourced to the issuer’s own audited filing; no independent institution independently reports ABB’s segment operational EBITA, so the underlying financial data is necessarily single-source. I do not treat the 23.0% incremental-margin assumption as a load-bearing conviction input without separate corroboration.

ABB’s FY2023 20-F does not, in the sections reviewed here, name a short list of top end customers. Therefore I do not fabricate customer names. The filing describes the revenue base as diversified across customers and geographies. Any claim that a specific corporation is a top-10 or top-5 customer would be needs primary source validation.
