Honeywell Split Creates Two New Stocks-But One May Be Overlooked

Honeywell's transformation from a sprawling industrial conglomerate into three separate public companies is now official, and investors are facing a new set of decisions. The split, which finalized in late June, leaves Honeywell Technologies (HON) focused on automation, Honeywell Aerospace (HONA) as a standalone aviation and defense supplier, and Solstice Advanced Materials (SOLS) as a pure-play materials business. According to reporting by TheStreet, the move echoes General Electric's multiyear breakup, with the potential for each business to eventually command a higher valuation than the old conglomerate-if they can prove their worth independently.

For shareholders, the mechanics of the split matter. Investors who held Honeywell stock as of June 15 received one share of Honeywell Aerospace for every two shares of Honeywell. Honeywell Technologies, which retained the HON ticker, then executed a 1-for-2 reverse stock split, reducing its outstanding shares to 317 million. The advanced materials arm, Solstice Advanced Materials, was spun off in October 2025. This restructuring creates two distinct investment profiles where there was once a single diversified company.

Automation and Aerospace Diverge

Honeywell Technologies now offers exposure to building, industrial, and process automation, while Honeywell Aerospace provides a direct play on commercial aviation, business jets, defense, and space. Early market reaction has been cautious, with investors weighing whether the sum of the parts will ultimately exceed the value of the former conglomerate. Jim Cramer, host of CNBC's "Mad Money," argues that it may take several quarters for the market to fully price in the potential of each business, especially as separation costs and accounting noise work through the financials.

Honeywell Technologies has already reported its first post-split earnings, showing second-quarter sales of $5.2 billion-up 3% year over year, or 4% organically, excluding the aerospace business. Orders jumped 16%, pushing the backlog above $20 billion. Building Automation revenues rose 9% on strong demand from data centers, health care, and hospitality projects. Industrial Automation sales increased 4%, while orders climbed 10%. Process Automation and Technology revenues slipped 1%, but orders surged 24%, hinting at possible improvement later in the year. Management raised its full-year sales outlook to $19.8-$20 billion and expects adjusted earnings of $8.05-$8.35 per share, with a target of $2 billion in free cash flow.

What to Watch Next

Investors will be watching several key issues in the coming quarters: whether Honeywell Technologies can convert its $20 billion backlog into profitable sales, if process automation orders translate into stronger growth in the second half, and how quickly separation and standalone costs decline. The first independent earnings report from Honeywell Aerospace, due August 5, will also be closely scrutinized for margin and cash flow clarity. There's also the question of whether each company will attract a more specialized shareholder base, potentially leading to higher valuations over time.

One risk is that the initial quarters after a breakup are often clouded by one-time charges, duplicated corporate costs, and complex accounting. In Honeywell's case, the aerospace business was included in consolidated results for the second quarter because the spin occurred just one day before quarter-end, creating a large deconsolidation gain under generally accepted accounting principles. This complexity supports the argument for patience as the market digests the new structure.

Aerospace: The Overlooked Piece?

While much attention has focused on Honeywell Technologies, some analysts see Honeywell Aerospace as the more intriguing long-term play. Aviation and defense companies often trade at premium valuations when they are sharply focused, and Honeywell Aerospace's customer base is broad-serving more than 10,000 clients and employing over 36,000 people. Its systems are installed on about 90% of airplanes currently in operation and are designed into more than 250 production platforms, according to company filings.

In 2025, Honeywell Aerospace reported $17.4 billion in sales, $4.3 billion in adjusted earnings before interest and taxes, and an $18 billion backlog. Management is targeting nearly $6.5 billion in adjusted EBIT by 2030, which would represent roughly 9% compound annual growth, though this is a goal rather than a guarantee. The company's large installed base supports a steady stream of aftermarket revenue from parts, repairs, and upgrades, which can help smooth out the cyclical swings of new aircraft production.

For investors seeking exposure to the aerospace sector without the direct risks of aircraft manufacturing, Honeywell Aerospace offers a differentiated option. This is especially relevant as the sector faces ongoing supply chain challenges and shifting demand, as seen in other industrial and technology segments. For example, Micron's recent U.S. chip investment highlights how supply constraints can reshape entire industries, including aviation.

Valuation and Market Implications

The bullish scenario is that both Honeywell Technologies and Honeywell Aerospace develop clearer identities and attract investors who value their specialized focus, leading to higher valuation multiples. The bear case is that duplicated costs, separation fees, and bumpy quarterly results delay the realization of any premium. As with other major corporate breakups, the real test will be whether management teams can deliver on growth and profitability targets now that they are operating independently.

Honeywell's breakup is a reminder that simplification can unlock value-but only if each new company proves it can thrive on its own. Investors should expect a period of adjustment as the market recalibrates its expectations and as each business establishes a track record as a standalone entity.

According to Honeywell's second-quarter 2026 earnings release, Honeywell Technologies reported $5.2 billion in sales and a $20 billion backlog, while Honeywell Aerospace ended 2025 with $17.4 billion in sales and $18 billion in backlog. These figures underscore the scale and growth potential of both businesses, but also highlight the need for careful analysis as the companies move forward independently.

Corporate breakups like Honeywell's are designed to create more focused businesses that can respond faster to market changes and investor demands. Yet, the process often brings short-term volatility and uncertainty. Investors considering shares of Honeywell Technologies or Honeywell Aerospace should pay close attention to how each company manages costs, executes on its backlog, and adapts to sector-specific risks. Over time, the market will judge whether the split delivers on its promise of greater value-or simply replaces one set of challenges with another.
