Duolingo (DUOL) CEO Luis von Ahn Exercises PSUs, Withholds 54,875 Shares

What Happened

  • Luis von Ahn, Duolingo's CEO and a 10% owner, converted 120,000 performance-based restricted stock units (PSUs) into Class B common stock on 2026-05-27. The conversion is reported as the exercise/conversion of a derivative (code M) with an acquisition of 120,000 shares at $0.00 (PSUs convert to shares, no cash exercise).
  • To satisfy tax withholding obligations, 54,875 of those shares were withheld/disposed (code F) at $107.82 per share, totaling $5,916,623.

Key Details

  • Transaction date: 2026-05-27; Form 4 filed 2026-05-29 (filed within the normal two-business-day window).
  • Conversion: 120,000 PSUs converted into 120,000 Class B shares (reported as M: disposed derivative / acquired shares).
  • Tax withholding: 54,875 shares withheld (F) at $107.82 each; total value withheld $5,916,623.
  • Shares owned after transaction: not specified in the provided filing excerpt.
  • Relevant footnotes:
    • F1/F2: These were performance-based RSUs (PSUs) that vest based on service and stock-price performance; PSUs represent contingent rights to one Class B share and vest over time (25% each anniversary of IPO service condition) and subject to performance hurdles and acceleration provisions.
    • F3: Class B shares convert into Class A shares at the holder’s option and automatically on certain events (transfers, dropping below 5% of total common stock, or death).
  • Transaction codes: M = exercise/conversion of derivative; F = shares withheld to pay tax liability.

Context

  • This was not an open-market buy or sell signaling a cash purchase or liquidity sale; it was the settlement of performance awards (PSUs) and the routine withholding of shares to cover taxes.
  • For retail investors, conversions/settlements of RSUs/PSUs are typically administrative (compensation-related) rather than direct market sentiment by the insider.

Footnotes (3)
  • [F1]The performance-based condition will be satisfied upon the Issuer's Class A common stock achieving certain stock price hurdles over a period of ten years. Vested PSUs will be settled by the issuance of the underlying Class B Common Stock on the first anniversary of vesting, subject to acceleration upon a termination of employment or a change in control of the Issuer.
  • [F2]Each Performance-Based Restricted Stock Unit ("PSU") represents a contingent right to receive one share of the Issuer's Class B Common Stock upon vesting. The PSUs vest upon the satisfaction of both a service-based condition and a performance-based condition. The service-based condition is satisfied as to 25% of the PSUs on each anniversary of the completion of the Issuer's initial public offering of Class A common stock based on the Reporting Person's continuous service as CEO to the Issuer through the applicable vesting dates, subject to acceleration upon a cessation of service as CEO as a result of death or permanent disability.
  • [F3]Each share of Class B Common Stock is convertible at any time at the option of the Reporting Person into one share of Class A Common Stock and has no expiration date. Each share of Class B Common Stock will convert automatically into one share of Class A Common Stock in connection with: (i) any transfer, whether or not for value, except for certain permitted transfers further described in the Issuer's amended and restated certificate of incorporation, (ii) such time as the aggregate number of shares of Class B Common Stock outstanding ceases to represent 5% of the aggregate number of shares of Common Stock outstanding, and (iii) the death of the Reporting Person.
