Form 4: Duolingo CEO Luis von Ahn's Future Stock Vesting & Tax Withholding

Duolingo CEO Luis von Ahn reported future vesting of performance-based restricted stock units and a related tax withholding transaction.

Summary

• Luis von Ahn, Duolingo's President & CEO, Director, and 10% Owner, reported changes in his beneficial ownership.
• On February 17, 2026, 120,000 Performance-Based Restricted Stock Units (PSUs) vested.
• These vested PSUs converted into 120,000 shares of Class B Common Stock.
• Following this, 53,640 shares of Class B Common Stock were disposed of at a price of $112.57 per share to cover tax liabilities.
• After these transactions, Luis von Ahn directly beneficially owns 540,000 PSUs and 3,352,995 shares of Class B Common Stock.
• Each PSU represents a contingent right to receive one share of Class B Common Stock upon vesting, which requires both service-based and performance-based conditions to be met.
• The service-based condition for PSUs is satisfied as to 25% annually from the IPO anniversary, contingent on continuous CEO service.
• The performance-based condition for PSUs requires Duolingo's Class A common stock to achieve certain price hurdles over a ten-year period.
• Vested PSUs will settle into Class B Common Stock on the first anniversary of vesting, with potential acceleration upon employment termination or change of control.
• Class B Common Stock is convertible 1:1 into Class A Common Stock at the holder's option and automatically under specific conditions (e.g., certain transfers, Class B falling below 5% of total common stock, or the reporting person's death).

Sentiment

Score: 6

Explanation: StockSavvy.ai views this as a neutral to slightly positive filing. It reports routine executive compensation events (vesting and tax withholding) under a pre-arranged plan, with the vesting of performance-based units indicating some level of achievement or expectation of future performance.

Positives

• The vesting of 120,000 Performance-Based Restricted Stock Units (PSUs) indicates that certain performance and service conditions were met or are expected to be met by the vesting date.
• The existence of performance-based equity aligns management incentives with shareholder value creation, as PSUs require Class A common stock to achieve specific price hurdles.

Negatives

• The disposal of 53,640 shares of Class B Common Stock for tax withholding purposes represents a reduction in direct ownership, although it is a standard practice for equity compensation.

Risks

• The performance-based condition for PSUs relies on Duolingo's Class A common stock achieving certain stock price hurdles over a ten-year period, which is subject to market volatility and company performance.
• The service-based condition for PSUs requires continuous service as CEO, meaning unvested PSUs could be forfeited if the service condition is not met (e.g., resignation, termination, unless accelerated by death or permanent disability).

Future Outlook

The filing indicates future vesting events for Performance-Based Restricted Stock Units (PSUs) tied to both continuous service as CEO and the achievement of specific Class A common stock price hurdles over a ten-year period. Vested PSUs will settle into Class B Common Stock on the first anniversary of vesting.

Industry Context

StockSavvy.ai notes that Form 4 filings are standard disclosures for insider transactions, providing transparency into executive and director stock ownership changes. The structure of performance-based equity compensation, requiring both service and stock price performance, is a common practice in the technology and growth sectors to align executive incentives with long-term shareholder value, similar to practices seen at companies like Alphabet or Meta Platforms.

Comparison to Industry Standards

• The use of Performance-Based Restricted Stock Units (PSUs) with both service and performance conditions is a common compensation structure for executives in high-growth technology companies, aligning with best practices observed at peers like Alphabet (GOOGL) or Microsoft (MSFT) where executive compensation often includes significant equity components tied to long-term performance metrics.
• The automatic conversion features of Class B Common Stock into Class A Common Stock under specific conditions (e.g., transfers, ownership thresholds, death) are typical for dual-class share structures designed to maintain founder control, a model also employed by companies such as Meta Platforms (META) and Snap Inc. (SNAP).
• The disposal of shares to cover tax liabilities upon vesting is a standard and expected practice for equity compensation, consistent with how executives at virtually all publicly traded companies manage their equity awards.

Stakeholder Impact

• Shareholders: The vesting of performance-based equity aligns the CEO's incentives with long-term shareholder value creation, as it requires stock price appreciation. The disposal for tax withholding is a routine event and does not signal a change in confidence.

Next Steps

• Continued service by Luis von Ahn as CEO to satisfy service-based vesting conditions for remaining PSUs.
• Achievement of specified Class A common stock price hurdles over the next ten years for the performance-based conditions of PSUs.
• Settlement of vested PSUs into Class B Common Stock on the first anniversary of their vesting dates.

Key Dates

Recommendation

This Form 4 filing details routine insider transactions related to executive compensation, specifically the vesting of performance-based restricted stock units and subsequent tax withholding. These are expected events, often pre-scheduled under Rule 10b5-1 plans, and do not provide new fundamental information about Duolingo's operational performance or strategic direction that would warrant a change in investment recommendation. Therefore, a 'hold' recommendation is appropriate as the filing itself does not present a catalyst for significant price movement or a re-evaluation of the company's intrinsic value.
