Allegion’s VP Controller and CAO Nickolas Musial Executes Stock Option Exercise and Share Sale Under Rule 10b5-1 Plan

Details on Stock Option Exercise and Share Sale by Executive Officer

Filed on July 27, 2026, the disclosure reveals that Nickolas A. Musial, Allegion’s Vice President, Controller, and Chief Accounting Officer, exercised 687 stock options on July 23, 2026, at an exercise price of $71.835 per share. On the same day, he sold 687 ordinary shares at $155 per share. The synchronized nature of the option exercise and share sale indicates a coordinated portfolio transaction executed within the confines of an approved trading plan.

The exercised options vested in equal installments on February 13 of 2018, 2019, and 2020, making them fully exercisable by the transaction date. The exercise price of $71.835 compared to the sale price of $155 per share reflects a gain of approximately $83.17 per share, highlighting significant appreciation in Allegion’s stock over the vesting period.

Compliance with Rule 10b5-1 Trading Plan

Both the stock option exercise and share sale were carried out under a Rule 10b5-1 trading plan that Musial adopted on March 11, 2026. Such plans allow insiders to set predetermined trading schedules, offering a defense against insider trading accusations when trades follow the plan’s terms. Musial’s use of this plan confirms the transactions were prearranged and compliant with insider trading regulations.

Rule 10b5-1 plans are commonly used by corporate insiders to manage portfolio diversification or rebalancing while adhering to securities laws. By establishing the trading schedule months in advance, insiders avoid timing issues that might otherwise raise regulatory concerns. Musial’s July 2026 transactions executed under this plan reflect pre-planned actions rather than reactive market moves.

Post-Transaction Beneficial Ownership

Following these transactions on July 23, 2026, Musial retains beneficial ownership of 6,798 ordinary shares of Allegion plc, held directly. This figure accounts for the 687 shares acquired through option exercise and the 687 shares sold. The disclosure confirms no indirect ownership arrangements, underscoring Musial’s direct stake in the company.

Musial’s continued shareholding signals sustained confidence in Allegion’s financial health and strategic outlook. Balancing the sale of exercised shares with maintaining a substantial position suggests a measured approach to portfolio management.

Transaction Pricing and Market Overview

The exercised stock options were granted at $71.835 per share, while the shares sold fetched $155 each on July 23, 2026. This price difference illustrates notable stock appreciation since the options vested between 2018 and 2020.

The disclosed prices represent actual execution values, providing insight into Allegion’s market activity on the transaction date. Although the filing does not specify the immediate market impact of Musial’s sale, investors often analyze such insider trades alongside remaining holdings to gauge executive sentiment on company valuation.

Executive Role and Regulatory Accountability

Nickolas A. Musial serves as Vice President, Controller, and Chief Accounting Officer at Allegion plc, overseeing accounting operations, financial reporting, and internal controls. His role ensures the accuracy and integrity of the company’s financial disclosures.

As a senior officer subject to Section 16 reporting, Musial’s securities transactions are publicly disclosed via Form 4 filings. This regulatory framework promotes transparency and ensures compliance with insider trading laws. Musial’s adherence to the Rule 10b5-1 plan and timely disclosures provide investors with clear insight into his trading activities.

Vesting Timeline and Option Grant Background

The stock options exercised followed a three-year vesting schedule with equal installments on February 13 of 2018, 2019, and 2020. This standard equity compensation approach aligns executive incentives with long-term company performance. By February 2020, the options were fully vested and exercisable.

Musial’s decision to exercise these options more than six years after full vesting indicates a prolonged holding period before monetizing the shares. This timing likely reflects strategic considerations regarding stock valuation and personal portfolio management.

Form 4 Filing and Regulatory Compliance

The Form 4 disclosure was filed on July 27, 2026, four business days after the July 23 transaction, complying with SEC requirements to file within two business days. The filing was signed by Tandra M. Foster, Attorney-in-Fact for Musial, confirming authorized submission.

The filing includes legal attestations warning against intentional misstatements or omissions, emphasizing the seriousness of accurate insider transaction reporting under federal law. This ensures investors receive trustworthy information on beneficial ownership and insider trading activities.

Enhancing Insider Trading Transparency
