Honeywell Divests Aerospace Business, Building Automation Becomes Core Growth Engine

Overview

This report analyzes Honeywell's imminent aerospace business divestiture, focusing on evaluating the investment value of the remaining company (RemainCo). Bernstein maintains a Market-Perform rating with a $233 target price (implying 8% upside). The report considers the divestiture a correct strategic move that allows management to focus on core automation businesses, but the outlook for the three remaining segments (Building Automation, Process Automation, Industrial Automation) is markedly divergent, requiring separate valuation for each business.

Core views

Building Automation (BA) is the most favored segment in the report. As RemainCo's largest, fastest-growing, and highest-margin business (projected NTM+1 EBIT approx. $2.4 billion), BA will receive the most management attention. Unlike competitors such as Johnson Controls and Siemens, Honeywell prioritizes Building Automation, whereas rivals focus on more attractive businesses like data center cooling. Additionally, rising electricity prices create structural demand for building energy efficiency optimization. Even if construction activity slows, cost-optimization solutions at the software layer maintain a clear value proposition. The competitive landscape is concentrated with high barriers to entry, and the moat is expected to be further solidified with AI applications. Process Automation and Technology (PA&T) is the least favored segment. Honeywell has 26% exposure to the Middle East in this business, far exceeding Emerson's 9%, creating valuation discount risks due to regional geopolitical volatility. Furthermore, PA&T has high dependency on the oil and gas industry, where refining capital expenditure expectations are structurally declining (due to capacity overhang and long-term demand uncertainty), with only LNG investments providing partial support. UOP business (catalysts and technology licensing) outlook is weak; reduced refinery utilization leads to fewer catalyst replacement needs, resulting in a 10% decline in organic growth for the business in 1Q26. The report values PA&T at 14-15x NTM+1 EBIT, lower than peers like Emerson and ABB which have higher software exposure. Industrial Automation (IA) business view is neutral. This department comprises six sub-segments, two of which—Warehouse Solutions (WWS) and Productivity Solutions (PSS)—have performed poorly due to post-pandemic overinvestment and have found buyers, with the sale expected to complete in the second half of 2026. After divestiture, the remaining businesses (sensors, safety monitoring, etc.) have a better outlook than PA&T but are smaller and fragmented, potentially receiving insufficient management attention. The report suggests management consider further divestitures or sales within this segment. IA is valued at 14-15x NTM+1 EBIT (projected EBIT approx. $1.1 billion). The Forge platform is considered a wildcard. It is Honeywell's hardware-agnostic software suite, positioned as the core for future growth, utilizing a SaaS model to create recurring revenue streams. The report acknowledges it creates customer value (cases showing tens of millions in annualized returns), but questions its technological differentiation—competitors like Johnson Controls' OpenBlue and Siemens' Building X offer similar optimization solutions. Honeywell's advantage lies in covering both building management and process automation simultaneously, which holds value in complex industrial scenarios. However, adoption remains in early stages, and there is a lack of serious financial disclosure (e.g., ARR revenue mix), requiring more data for validation.

Analysis framework

The report employs a Sum-of-the-Parts (SOTP) valuation methodology for Honeywell, the standard approach for analyzing diversified conglomerates. First, the company is split by business segment, comparable companies are selected to determine valuation multiples, and these are summed to derive the total valuation. BA is assigned 17-19x NTM+1 EBIT (taking the lower end of the range due to the lack of pure-play peers and sector-wide elevation caused by data center exposure). PA&T and IA are both assigned 14-15x multiples (with discounts considering catalyst businesses, Middle East exposure, and smaller sub-segment sizes). Assuming RemainCo retains approx. $15 billion in debt, the implied value is $101-113 per share for RemainCo, taking the midpoint of $107. Adding the aerospace business valuation (20x NTM+1 EPS, projected $11.64) results in a total target price of $233. The report's analytical framework follows a logical chain: 'Business Segmentation → Industry Outlook → Competitive Landscape → Valuation Multiples'. For each business segment, the analysis first examines revenue mix, margins, and growth outlook, then evaluates industry drivers (e.g., rising electricity costs driving BA, declining refining CapEx suppressing PA&T), compares competitor differentiation strategies, and finally determines reasonable multiples based on peer valuations. This bottom-up analysis helps identify value distribution within a diversified company and avoids obscuring structural differences between businesses through aggregate valuation.

Methodology notes

  SOTP Sum-of-the-Parts

  Splits a diversified company by business segment, selects comparable companies to determine valuation multiples, and sums them up. Applicable to conglomerates with large business differences and divergent growth prospects, avoiding masking internal value distribution through aggregate valuation.

• Industry/Industrial Analysis FrameworkSupply and Demand Framework

  Supply and Demand Framework

  Analyzes supply-side factors (competitive landscape, barriers to entry) and demand-side factors (rising electricity costs driving BA demand, declining refining CapEx suppressing PA&T demand) for each business segment to assess industry prosperity direction.

• Competition and Strategy FrameworkMoat / competitive advantage

  Moat/Competitive Advantage

  Evaluates BA business barriers (high trust component, difficult for new entrants) and the moat solidifying with deeper AI applications to judge long-term competitive positioning.

• Corporate Fundamentals and Financial Framework

  Management Bandwidth Allocation Analysis

  Analyzes how management attention is allocated across businesses post-divestiture. Honeywell prioritizes BA, whereas competitors like JCI have other more attractive businesses like data centers that divert attention, constituting a relative advantage for Honeywell.

  Expectation Gap/Expectation Management

  The report notes that the market may underestimate PA&T business exposure to Middle East geopolitical risks (26% vs. 9% for peers), creating a potential source of expectation gap.

Impact & implications

For Honeywell, divesting the aerospace business is a correct strategic move to focus on core automation, but the divergent prospects of the remaining three businesses mean the company is no longer a homogeneous automation play. Building Automation will become the primary growth driver, benefiting from rising electricity prices and management focus. Process Automation faces Middle East geopolitical risks and downward pressure on oil & gas CapEx. Industrial Automation requires further portfolio rationalization. For investors, RemainCo's valuation logic will shift from conglomerate discount to that of a purer automation company, but attention must be paid to whether the commercialization progress of the Forge platform can support valuation premiums. The report believes current valuation reflects most information and maintains a neutral rating.

Risks

• Stable or falling electricity prices, weakening demand drivers for Building Automation
• Weak or delayed LNG projects not fully priced into the market
• Organizational drag arising from aerospace business divestiture
• Geopolitical volatility in the Middle East affecting PA&T business growth
• Persistently low refinery utilization impacting UOP catalyst business
• Slow adoption rate of Forge platform failing to support valuation premium

What to watch

• Continued strong performance of Building Automation business
• Market uptake of Forge products and mix of recurring revenue
• Margin expansion in IA business after WWS/PSS divestiture
• Further financial disclosures from RemainCo investors (e.g., ARR revenue)
• Execution effectiveness of management post-aerospace divestiture
