Honeywell Aerospace (NASDAQ: HONA) Securities Class Action: Investor Rights and November 23, 2026 Lead Plaintiff Deadline

The complaint alleges two principal categories of allegedly undisclosed information.

First, plaintiff alleges that Honeywell Aerospace did not adequately disclose the importance of a small number of constrained suppliers to the company's ability to generate sales and profits.

Second, plaintiff alleges that investors were not adequately informed that the company was under investigation concerning potential False Claims Act liability arising from cybersecurity requirements associated with a Department of Defense contract.

According to the complaint, defendants failed to adequately disclose:

• that a small percentage of suppliers had a disproportionate effect on sales;
• that those suppliers faced supply constraints;
• that the constraints were reasonably likely to adversely affect sales and profitability;
• that a False Claims Act cybersecurity investigation existed; and
• that defendants' positive statements allegedly lacked a reasonable basis as a result.

These are allegations in a newly filed complaint and have not been proven.

Honeywell Aerospace became a standalone public company through its spin-off from Honeywell on June 29, 2026.

Honeywell shareholders of record as of June 15 received one Honeywell Aerospace share for every two Honeywell shares held. HONA began regular-way Nasdaq trading on June 29.

This date is also the first day of the presently alleged securities class period, which is central to both class membership and derivative standing in this case.

Before the spin-off, Honeywell Aerospace's Information Statement discussed extensive supply-chain investments and described measures intended to improve resiliency.

At its June 3 Investor Day, the company acknowledged industry-wide supply challenges while forecasting 7%–9% organic sales growth and approximately $4.65–$4.75 billion in adjusted EBIT for 2026. CFO Joshua Jepsen stated that the outlook was supported by the company's ability to meet robust customer demand through its supply chain and manufacturing footprint.

The complaint alleges that investors were not adequately informed about the disproportionate effect that a small group of constrained suppliers could have on the company's ability to convert its large backlog and customer demand into revenue.

After the market closed on August 5, Honeywell Aerospace announced second-quarter results and reduced its 2026 outlook. The company revised:

• Organic growth: 7%–9% → 4%–5%;
• Adjusted EBIT: $4.65–$4.75 billion → $4.35–$4.45 billion; and
• Adjusted EBIT growth: 7%–10% → flat-to-3%.

CEO James Currier stated that customer demand remained significant but acknowledged that the company's supply base had not ramped as expected.

According to the complaint, HONA fell $47.17, or approximately 23.16%, to $156.47 on August 6.

The complaint highlights an explanation provided by Currier during the earnings call.

Currier stated that approximately 98% of Honeywell Aerospace's more than 3,000 suppliers were performing well, while approximately 2% fell into categories management considered constrained or critical.

He explained, however, that the small number of constrained suppliers could have a disproportionate effect on Honeywell Aerospace's output. According to the complaint, management gave an example where approximately $15–$16 million in overdue parts from one supplier could prevent completion of products representing hundreds of millions of dollars of potential revenue.

The plaintiff alleges that the significance of this concentration risk should have been adequately disclosed earlier.

Honeywell Aerospace's August results also showed substantial demand and growth. The company reported:

• $4.5 billion in quarterly sales, up 5%;
• backlog of approximately $18.2 billion, up 9%;
• trailing-twelve-month orders up 8%;
• Commercial Original Equipment sales up 6%;
• Commercial Aftermarket sales up 8%; and
• Defense and Space sales up 3%.

Currier stated that customer demand remained significant and that long-term aerospace trends remained favorable, while acknowledging supply constraints.

The lawsuit therefore does not simply allege that Honeywell Aerospace had a weak business. Rather, the plaintiff alleges that investors were not adequately informed about the severity and financial consequences of particular supplier bottlenecks before the August guidance reduction.

On September 1, the U.S. Department of Justice announced that Honeywell Aerospace had agreed to pay $2,042,518 to resolve allegations under the False Claims Act concerning cybersecurity requirements in a Department of Defense contract.

The allegations concerned conduct from April 2020 through December 2023, when the aerospace business was still part of Honeywell International. The DOJ stated that the allegations concerned compliance with NIST SP 800-171 cybersecurity requirements on one network used in connection with the government contract.

The settlement resolved allegations only. There was no determination of liability.

According to the securities complaint, HONA declined another $3.87, or 2.45%, to $154.24 following the announcement.

The securities plaintiff does not simply challenge the cybersecurity conduct itself. The complaint alleges that Honeywell Aerospace knew of a government investigation but did not adequately disclose it to investors.

The complaint specifically points to Honeywell Aerospace's August 5 Form 10-Q, which generally disclosed that the company faced various lawsuits, investigations, and claims. Plaintiff alleges that this generalized disclosure was inadequate because the company allegedly did not specifically disclose the False Claims Act cybersecurity investigation.

Whether federal securities law required additional disclosure will be an issue in the litigation.

Section 10(b) and Rule 10b-5

The complaint asserts federal securities-fraud claims under Section 10(b) and Rule 10b-5 against Honeywell Aerospace, Currier, and Jepsen.

Section 20(a)

The complaint asserts Section 20(a) controlling-person claims against Currier and Jepsen.

The complaint currently identifies June 29, 2026 through September 1, 2026 as the alleged class period. That period begins on the day Honeywell Aerospace became an independent public company.

Investors should preserve complete brokerage statements and trade confirmations.

The PSLRA notice was published September 22, 2026. The calculated deadline to seek PSLRA lead plaintiff appointment is November 23, 2026, because the statutory 60th day falls on Saturday, November 21, and the period continues to the next non-weekend/non-holiday day (absent a contrary court order).

Do I Have to Become Lead Plaintiff?

Generally, no. The lead plaintiff is the investor or investor group appointed by the court to actively represent the class and supervise class counsel. Most investors remain passive class members.

Lead Plaintiff Deadline ≠ Settlement Claim Deadline

The notice itself states that investors may take no action and remain absent members of the proposed class.

The complaint currently contains somewhat different formulations. The introductory portion describes the action as being brought for “open-market purchasers” during the class period, while the Rule 23 section later refers to persons who “purchased or otherwise acquired” HONA shares during that period.

Investors who received HONA solely through the June 29 spin-off should therefore not assume that they are necessarily included or excluded. The class definition may be clarified or amended as the case develops.

No. Honeywell Aerospace became an independent company on June 29, 2026 and trades under HONA. The remaining Honeywell automation company became known as Honeywell Technologies and continues to trade under HON. The new complaint names Honeywell Aerospace Inc. and its executives James Currier and Joshua Jepsen.

The federal securities case seeks recovery for investor losses. A derivative action is different: a shareholder seeks to enforce a claim belonging to the corporation itself.

Julie & Holleman LLP is separately investigating potential shareholder derivative claims and corporate-governance claims on behalf of current Honeywell Aerospace shareholders. Because Honeywell Aerospace was only spun off on June 29, derivative standing concerning pre-spin conduct may present unusual issues, and no assumption should be made that every spin-off recipient can challenge all pre-spin conduct.

We are particularly interested in shareholders who:

• received HONA through the June 29 spin-off and continue to hold those shares; or
• purchased HONA after the spin-off, owned the shares when later potentially actionable conduct occurred, and continue to hold them.

Potential areas for investigation may include:

• how management and the board monitored critical supplier constraints;
• when the disproportionate revenue impact of key suppliers became known;
• what information concerning supply-chain risks reached the board;
• how corporate guidance was evaluated;
• what the post-spin board knew regarding the False Claims Act cybersecurity investigation;
• how government-contract cybersecurity compliance was monitored;
• how inherited legal liabilities were handled following the spin-off; and
• whether any alleged fiduciary misconduct caused harm to Honeywell Aerospace itself.

No determination has been made that viable derivative claims exist. Counsel may evaluate whether a Delaware books-and-records investigation or other investigative steps are appropriate.

Julie & Holleman LLP is investigating allegations involving Honeywell Aerospace, HONA, supply-chain constraints, supplier concentration, revenue guidance, cybersecurity, Department of Defense contracting, the False Claims Act investigation, and post-spin corporate governance. We are interested in hearing from:
