RPM International Chairman and CEO Frank Sullivan Executes Stock Sale Following Performance Unit Vesting

Performance Stock Unit Vesting and Tax-Driven Equity Disposition

Frank C. Sullivan, who serves as Chairman and Chief Executive Officer of RPM International, executed a stock sale on July 19, 2026, stemming from the vesting of performance stock units originally granted in 2023 under the company's equity compensation plan. The 3,813 shares were sold back to the issuer at a transaction price of $105.08 per share. According to the disclosure, this disposition occurred in accordance with plan provisions that permit executives to satisfy personal tax withholding obligations through share sales when equity awards vest. This practice is common among publicly traded companies and allows executives to retain beneficial ownership while meeting their immediate tax liabilities without requiring external financing.

The performance stock units that vested in July 2026 represent a component of long-term incentive awards designed to align executive compensation with company and shareholder performance over multi-year periods. RPM International structures its executive compensation to include restricted stock awards, performance-based equity grants, and stock appreciation rights, with vesting schedules that typically span multiple years. The July 19 transaction reflects the mechanics of how performance-based equity awards settle when vesting occurs and executives need liquidity to cover tax withholding requirements on the appreciated value of those awards.

Sullivan's Continuing Direct and Indirect Beneficial Share Ownership

Following the July 2026 sale, Sullivan maintained substantial direct beneficial ownership of RPM International common stock. The disclosure indicates that as of July 19, 2026, Sullivan owned 1,013,277 shares of common stock on a direct basis, representing his largest category of beneficial ownership in the company. This direct shareholding demonstrates meaningful alignment between the CEO and RPM shareholders, as executive ownership of company equity typically incentivizes management to act in the long-term interests of the corporation and its investors. The magnitude of Sullivan's direct holdings suggests significant personal investment in the organization's strategy and operational performance.

In addition to direct share ownership, Sullivan's beneficial ownership structure includes holdings through the Thomas C. Sullivan Irrevocable Trust established for his benefit, which the disclosure states holds 15,600 shares of RPM common stock as of the reporting date. Sullivan also maintains an indirect beneficial interest in approximately 5,247 shares held within RPM International's 401(k) retirement plan and trust, managed by Fidelity Trust Management Company as trustee. Together, these direct and indirect holdings create a comprehensive ownership position that extends across multiple ownership vehicles, which is typical for senior executives with long tenures at major publicly traded industrial and specialty chemical manufacturers.

Stock Appreciation Rights Grants and Long-Term Incentive Structure

The disclosure reveals that Sullivan holds 1,231,300 stock appreciation rights as of July 2026, representing a significant derivative security position. According to the report, these stock appreciation rights were granted between 2019 and 2026 in transactions exempt under Securities and Exchange Commission Rule 16b-3, which governs certain transactions by officers and directors under approved equity plans. The rights vest in four equal annual installments beginning one year after the grant date, and each grant expires ten years from its original grant date. This multi-year vesting structure for derivative securities aligns management incentives with sustained company performance and shareholder value creation over extended periods.

The stock appreciation rights mechanism provides executives with an economic interest in share price appreciation without requiring immediate capital outlay or the dilution associated with traditional stock option grants. RPM International's use of this compensation vehicle suggests a deliberate strategy to tie senior executive wealth creation to the company's equity performance while maintaining flexibility in how executives choose to realize gains from their derivative holdings. The significant size of Sullivan's accumulated stock appreciation rights position indicates that this has been a material component of his executive compensation package over the seven-year period spanning the grant dates disclosed in the filing.

RPM International's Business Model and Executive Incentive Alignment

RPM International Inc. operates as a specialty chemicals and coatings manufacturer, serving industrial and consumer markets with a diversified portfolio of protective coatings, sealants, primers, and related chemical products. The company's business model spans multiple operating segments that serve construction, industrial, consumer, and specialty markets, generating revenue through the sale of branded and private-label chemical and coating products. As Chairman and CEO, Frank Sullivan leads a publicly traded company with significant scale, employing thousands of workers globally and maintaining manufacturing, distribution, and research facilities across numerous countries. The executive compensation structure disclosed in this filing reflects the scale and complexity of managing such a diversified chemical manufacturing enterprise.

RPM International's incentive compensation program, as evidenced by the equity grants disclosed in Sullivan's beneficial ownership report, appears designed to reward both annual performance through restricted stock awards and longer-term value creation through performance stock units and stock appreciation rights. The vesting of performance-based equity in 2026 and the large accumulated position in stock appreciation rights suggest that RPM's board of directors has implemented a multi-year performance framework intended to ensure management focus on sustained earnings growth, operational efficiency, and shareholder return generation. This approach aligns the interests of the CEO with those of equity investors and reflects corporate governance practices common among large-capitalization industrial and specialty chemical companies.

Timing and Market Context of the Equity Transaction

The July 19, 2026 stock sale occurred at a transaction price of $105.08 per share, reflecting the fair market value of RPM International common stock on the vesting date of Sullivan's performance stock units. The company did not disclose specific share price movements, trading volume, or market conditions surrounding this transaction in the beneficial ownership report. The disclosure document itself represents a standard regulatory filing requirement for officers and directors of public companies, filed on July 21, 2026, two trading days after the underlying equity transaction. Investors monitoring insider transactions may consider the context and timing of such sales as one data point among many in evaluating executive confidence and portfolio management decisions.

Tax-motivated equity sales by executives following vesting events are routine corporate governance occurrences and typically do not signal material changes in executive sentiment regarding company prospects. Rather, such transactions represent the practical mechanics of equity compensation administration, where executives must address tax withholding obligations that arise when restricted awards and performance units convert to common shares. The magnitude and frequency of such sales can vary considerably based on the size of vesting grants in any given year and the tax obligations those grants generate, independent of underlying business conditions or executive confidence in company strategy.

Regulatory Filing Requirements for Officer and Director Transactions

The disclosure filed on July 21, 2026, represents a mandatory regulatory obligation under Section 16(a) of the Securities Exchange Act of 1934, which requires officers, directors, and significant shareholders of publicly traded companies to report changes in their beneficial ownership of company securities. Frank C. Sullivan's role as both Director and Officer of RPM International triggers these reporting requirements, and the form filed captures all transactions and beneficial ownership changes as of the date of the transaction. The report was executed on Sullivan's behalf by Gregory J. Dziak, identified as his attorney-in-fact pursuant to a power of attorney dated September 26, 2013, on file with the Commission. This delegation of signature authority is a common practice for senior executives managing multiple transaction filings and compliance obligations.

The regulatory framework governing these disclosures exists to provide transparency to investors regarding the securities holdings and trading activities of company insiders. By disclosing beneficial ownership positions—including both direct holdings and indirect interests held through trusts, retirement plans, and other vehicles—the reporting regime enables public shareholders to monitor whether corporate insiders maintain meaningful ownership stakes aligned with shareholder interests. The requirement to report transactions at the time they occur, combined with the requirement to state ownership positions following each transaction, creates a public record of insider activity that market participants can analyze when evaluating corporate governance quality and insider sentiment regarding company prospects.

Distinction Between Direct and Indirect Beneficial Ownership Categories

Sullivan's total beneficial ownership of RPM International stock comprises multiple ownership categories that the reporting requirement clearly delineates. The 1,013,277 shares owned directly represent securities held in Sullivan's own name or held by a broker for his direct account. The 15,600 shares held indirectly through the Thomas C. Sullivan Irrevocable Trust represent a separate ownership vehicle, typically established for estate planning or tax efficiency purposes, while still constituting beneficial ownership under securities law. The 5,247 shares held in the 401(k) retirement plan represent participant interests in company securities held within a tax-qualified employee benefit arrangement. Together, these three categories totaled approximately 1,034,124 shares of beneficial ownership as of July 19, 2026, before accounting for the derivative securities position in stock appreciation rights.

The layered ownership structure disclosed in the report is representative of sophisticated wealth management practices typical among senior executives at large publicly traded corporations. By utilizing trusts, retirement plans, and direct ownership vehicles, executives can manage tax efficiency, estate planning objectives, and liquidity needs while maintaining clear beneficial ownership under securities law. The disclosure requirements ensure that regardless of the specific ownership vehicle employed, the public record captures the full extent of an insider's economic interest in company securities, preventing executives from obscuring their true ownership positions through complex organizational structures.

Explanation of Performance Stock Unit Mechanics and Tax Withholding Provisions

The report includes an explanation noting that on July 19, 2026, a portion of Sullivan's performance stock units previously granted in 2023 vested pursuant to the company's equity compensation plan. Upon vesting, the report indicates that Sullivan disposed of 3,813 shares back to RPM International to satisfy his personal tax withholding obligations on the value of the vesting award. This mechanism is a standard provision in equity compensation plans, permitting executives to elect a "net share settlement" approach whereby the company withholds shares equal to the employee's estimated tax liability when an award vests. This approach eliminates the need for executives to sell shares in the open market or arrange external financing to cover taxes owed on compensation income.

The performance stock units granted in 2023 created an entitlement to receive shares contingent upon both the passage of time and the satisfaction of specified performance metrics or conditions. Upon vesting, those performance stock units converted to an equivalent number of shares of common stock. The disclosure separately notes that the 1,013,277 total direct holdings following the July transaction includes 23,970 shares issued as "Performance Earned Restricted Stock," confirming that at least a portion of Sullivan's vested awards during this period involved performance-based conditions that were satisfied. The remaining balance of the vested award (3,813 shares) was disposed of through the tax withholding mechanism, leaving Sullivan with a net increase in beneficial ownership from the vesting event after accounting for shares sold to cover taxes.

Future Vesting and Derivative Security Expiration Timelines

The accumulated position of 1,231,300 stock appreciation rights disclosed in the report will continue to generate economic interest for Sullivan over time as previously granted tranches vest according to their contractual schedules. The filing notes that these rights vest in four equal annual installments beginning one year after each grant date, and each grant expires ten years from its original grant date. Given that the oldest grants date to 2019 and the most recent grants are from 2026, Sullivan will realize additional vesting events and potential expirations across the period from 2027 through 2036. The ongoing vesting of these derivative securities will create periodic opportunities for Sullivan to exercise, hold, or monetize his position in stock appreciation rights, subject to applicable trading window restrictions and Securities and Exchange Commission rules governing insider transactions.

The structure of stock appreciation rights vesting in equal annual tranches over a four-year period is designed to encourage retention of executives and align their interests with sustained company performance. By staggering the vesting of large grants across multiple years, the compensation structure creates an incentive for senior executives to remain employed through vesting milestones and to focus on performance throughout the vesting period rather than concentrating on near-term objectives. As stock appreciation rights approach their ten-year expiration dates, Sullivan will face choices regarding exercise, liquidation, or non-exercise depending on the stock price relative to exercise prices and his overall portfolio objectives at that time.
