Applied Optoelectronics Senior VP David C. Kuo Executes Tax-Related Share Surrenders Following RSU Vesting

Overview of Applied Optoelectronics and Executive Equity Compensation

Applied Optoelectronics Inc. specializes in fiber-optic networking products tailored for data centers, cable access, and telecommunications sectors requiring high bandwidth. The company produces optical modules, subsystems, and components that enhance data transmission speeds and capacity for network operators and equipment manufacturers. As a publicly listed entity under SEC regulations, AAOI adopts standard executive compensation frameworks, including equity-based awards for senior officers.

Restricted stock units are a prevalent form of executive compensation aimed at aligning management’s interests with shareholders over specified vesting periods. These awards typically vest over multiple years, and upon vesting, recipients must satisfy tax obligations. Commonly, this is achieved by surrendering a portion of vested shares back to the company at fair market value, a process known as net share settlement or tax-withholding share surrender.

Details of July 2026 Share Surrender Transactions by David C. Kuo

On July 22, 2026, David C. Kuo, Senior Vice President and Chief Legal Officer, executed four separate share surrender transactions related to RSU vesting. Each transaction involved shares held in direct beneficial ownership, all surrendered at $119.26 per share. These transactions corresponded to RSU grants awarded at different times during his tenure.

The first transaction surrendered 1,869 shares from the RSU grant dated June 26, 2023. The second involved 472 shares from the April 29, 2024 grant. The third transaction included 516 shares tied to the April 11, 2025 grant. The final transaction surrendered 407 shares from the February 9, 2026 grant. Collectively, these four transactions resulted in the surrender of 3,264 shares to satisfy tax-withholding requirements.

Kuo’s Beneficial Ownership After Share Transactions

Following the completion of these transactions, Kuo’s direct beneficial ownership of Applied Optoelectronics common stock totaled 145,814 shares. This figure reflects the net effect of the RSU vesting events and the associated tax-withholding share surrenders executed on July 22, 2026. All shares are held directly in Kuo’s name or accounts under his control, rather than indirectly through trusts or other entities.

This ownership stake underscores Kuo’s significant equity position in the company, accumulated through equity awards and possible purchases during his tenure. It highlights the company’s commitment to aligning executive leadership interests with shareholder value creation through meaningful equity participation.

Tax-Withholding Procedures in Executive Equity Awards

The disclosed share surrenders illustrate standard tax-withholding mechanisms used by public companies when RSUs vest for executives and employees. Upon vesting, recipients incur tax liabilities based on the fair market value of the shares. To satisfy federal, state, and potentially international tax withholding, companies often allow employees to surrender a portion of vested shares back to the company.

This net share settlement enables executives to realize the economic benefits of their awards while the company covers tax obligations by withholding shares. The valuation price used for these transactions is generally the closing stock price on the vesting date or a related date. In Kuo’s case, all shares were surrendered at $119.26 per share, indicating the applicable valuation for determining the number of shares needed to cover tax withholding.

Recurring Equity Award Grants and Vesting Schedule

Kuo has received RSU grants periodically throughout his time with Applied Optoelectronics, with documented awards in June 2023, April 2024, April 2025, and February 2026. This pattern aligns with competitive executive compensation practices in technology and telecommunications manufacturing, encouraging long-term retention and performance.

The simultaneous vesting and settlement of these four RSU grants around July 22, 2026, suggest typical three- or four-year vesting schedules. For example, the June 2023 grant would be nearing full vesting by mid-2026 under a three-year schedule. This structure supports retention and aligns compensation with company performance over time.

Regulatory Filings and Insider Reporting Compliance

Kuo’s transactions were disclosed via a Form 4 filing, reflecting his status as a Section 16 reporting person under the Securities Exchange Act of 1934. This designation includes officers, directors, and significant shareholders of public companies, requiring reporting of ownership changes within two business days. The filing was signed on July 23, 2026, meeting regulatory deadlines for the July 22 transactions.

Share surrenders for tax withholding are routine administrative actions not typically subject to insider trading restrictions, as they are non-discretionary. Nonetheless, executives must observe trading windows and blackout periods. Transparent reporting of these transactions provides investors with insight into insider ownership changes.

Applied Optoelectronics’ Market Role and Business Focus

Applied Optoelectronics operates in the optical networking and telecommunications equipment industry, supplying high-capacity fiber-optic solutions for data transmission. Its product lineup includes optical modules, transceivers, and integrated subsystems serving telecom providers, cable operators, and data centers. The sector demands ongoing innovation in speed, efficiency, and form factor to meet customer needs.

As a publicly traded technology company, Applied Optoelectronics emphasizes attracting and retaining skilled executives and technical staff. Equity compensation, such as RSUs granted to senior leaders like Kuo, is critical for maintaining competitive talent capable of driving strategic initiatives and operational success in a highly competitive industry.

Market Valuation Context of the Share Transactions

The share surrender transactions occurred at $119.26 per share on July 22, 2026, reflecting the market’s valuation of Applied Optoelectronics stock at the time of RSU vesting. This price indicates investor sentiment regarding the company’s financial performance, competitive position, and industry outlook.

While the insider filing does not specify reasons for this valuation, the price served as the fair market value for calculating the number of shares surrendered to cover tax obligations. Using the market price ensures compliance with securities laws and tax regulations governing equity compensation.

Significance of Insider Ownership and Shareholder Alignment

Kuo’s retention of 145,814 shares after the July 2026 tax-related share surrenders highlights his meaningful equity stake in Applied Optoelectronics. This substantial ownership aligns his interests with those of shareholders, as fluctuations in stock price directly impact his personal investment value. Institutional investors and analysts often view significant insider ownership positively, interpreting it as management’s confidence in the company’s future and commitment to long-term value creation.

The continued accumulation of shares through RSU vesting, despite necessary share surrenders for taxes, demonstrates the effectiveness of the company’s equity compensation program in fostering executive ownership. Kuo’s sizable shareholding underscores the importance of equity incentives within Applied Optoelectronics’ overall executive pay strategy.
