Unless otherwise ordered by the arbitrator under applicable law, the Company and Executive shall each bear its, their, his, or her own expenses, such as expert witness fees, filing fees, and attorneys' fees and costs.

Miscellaneous. This Agreement, collectively with the Confidentiality Agreement, the Indemnification Agreement and any agreements evidencing Executive's RSUs, comprises the entire agreement between the parties with regard to the subject matter hereof and supersedes, in their entirety, any other agreements between Executive and the Company with regard to the subject matter hereof, including, without limitation, the Offer Letter and Severance Agreement.

It is intended that payments and benefits under this Agreement comply with, or be exempt from, the provisions of Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the date of this Agreement ("Section 409A"). This Agreement will be interpreted and administered in a manner consistent with this intent. Each payment and each provision of benefits described in this Agreement will be considered a separate payment and not one of a series of payments for purposes of Section 409A. In no event will any payment under this Agreement that constitutes "nonqualified deferred compensation" for purposes of Section 409A be subject to offset by any other amount unless otherwise permitted by Section 409A. (b) Specific Exemptions. If any reimbursements or in-kind benefits provided by the Company or any Releasee pursuant to this Agreement would constitute "nonqualified deferred compensation" for purposes of Section 409A, such reimbursements or in- kind benefits will be subject to the following rules: (A) the amounts to be reimbursed, or the in-kind benefits to be provided, will be determined pursuant to the terms of the applicable benefit plan, policy or agreement and will be limited to Executive's lifetime and the lifetime of Executive's eligible dependents; (B) the amounts eligible for reimbursement, or the in-kind benefits provided, during any calendar year may not affect the expenses eligible for reimbursement, or the in-kind benefits provided, in any other calendar year; (C) any reimbursement of an eligible expense will be made on or before the last day of the calendar year following the calendar year in which the expense was incurred; (D) Executive's right to an in-kind benefit or reimbursement is not subject to liquidation or exchange for cash or another benefit and (E) if Executive is a "specified employee" within the meaning of Section 409A, no payments of any of such severance or other benefit shall be made for six (6) months plus one (1) day after the "separation from service," or, if earlier, upon Executive's death (the "New Payment Date"). The aggregate of any such payments that would have otherwise been paid during the period between the "separation from service" and the New Payment Date shall be paid to Executive in a lump sum on the New Payment Date. 15. Taxes. Executive understands and agrees that all payments under this Agreement will be subject to appropriate tax withholding and other deductions. To the extent any taxes may be payable by Executive for the benefits provided to Executive by this Agreement beyond those withheld by the Company, Executive agrees to pay them. 16. Maintaining Confidential Information. Nothing in this Agreement or the Confidentiality Agreement will be construed to prohibit Executive from (i) pursuing unemployment or workers compensation benefits; (ii) filing a charge or complaint with the Equal Employment Opportunity Commission ("EEOC"), the National Labor Relations Board ("NLRB"), or any similar state government agency or commission, provided, however, Executive releases and waives Executive's right to receive damages or other relief in connection with any such matter to the maximum extent permitted by applicable law; (iii) communicating with, cooperating with, or reporting wrongdoing to the Securities and Exchange Commission ("SEC"), the Financial Industry Regulatory Authority, the EEOC, the NLRB, the Occupational Safety and Health Administration, the Commodity Futures Trading Commission, the Department of Justice ("DOJ"), or any other federal, state or local government agency or commission (collectively, "Government Agencies"), or otherwise participating in any investigation or proceeding that may be conducted by a Government Agency, including providing documents or other information, without notice to the Company; (iv) receiving a reward for information provided to the Docusign Envelope ID: C3B807F2-2CE8-43BD-B341-426E7B83B4EC

B. The Board believes that it is in the best interests of the Company and its stockholders to provide Executive with an incentive to continue Executive's employment and to motivate Executive to maximize the value of the Company upon a Change in Control (as defined below) for the benefit of its stockholders.

**DUOLINGO ANNOUNCES CFO TRANSITION** 

**GILLIAN MUNSON, BOARD MEMBER & CHAIR OF AUDIT COMMITTEE, TO BECOME CFO**

**Pittsburgh, PA — January 12, 2026** - Duolingo, Inc. (NASDAQ: DUOL), the world's leading mobile learning platform, today announced Gillian Munson as Chief Financial Officer ("CFO"), effective February 23, 2026. Matt Skaruppa will step down after nearly six years with the company; he will remain CFO until Ms. Munson starts her new role, at which time he will assume an advisory role to help provide for a seamless transition.

"I want to thank Matt for all he's done for Duolingo," said Luis von Ahn, Duolingo's Co-Founder and CEO. "He's been an exceptional financial leader and built a world-class team that has shaped our trajectory as a public company, positioning Duolingo for long-term growth."

"Gillian steps into this role with a track record of strong financial leadership and a deep understanding of Duolingo," von Ahn said. "I look forward to partnering with her in this new capacity. I'm confident she is the right leader to help us capitalize on the opportunity ahead to bring education to billions of people."

Under Skaruppa's leadership, Duolingo executed a successful initial public offering and achieved six consecutive years of disciplined financial growth.

"Duolingo has been the most rewarding chapter of my career," Skaruppa said. "From taking Duolingo public, to scaling the business far beyond our IPO expectations, and building a finance organization that matches the creativity and excellence of the rest of the company, I'm proud of what we've accomplished together: sustainable growth, strong profitability, and a culture that never lost its sense of fun."

Munson assumes the CFO role after serving on the Duolingo Board of Directors since 2019 as Chair of the Audit, Risk and Compliance Committee. She was most recently the CFO of Vimeo and previously held CFO positions at Iora Health, Inc. and XO Group Inc., in addition to leadership positions at Union Square Ventures, Allen & Company, Symbol Technologies, and Morgan Stanley. She currently serves as Audit Chair and Board member at Phreesia (PHR).

"When Luis, Matt, and the Board approached me about the possibility of stepping into this role, it was an easy yes," Munson said. "Having worked closely with leadership as a Board member, I've developed deep respect for Duolingo's culture, operating discipline, and momentum. Few companies combine this level of engagement and impact with strong financial fundamentals, and I'm honored to step into the CFO role to help advance Duolingo's long-term mission to bring the best education to the world."

**Company Provides Update on Fourth Quarter 2025**

Today Duolingo also announced a preliminary update on operating metrics for the fourth quarter ending December 31, 2025. The Company's preliminary results show fourth quarter DAU growth of approximately 30% year over year and bookings at or slightly above the high end of its previously announced guidance range of $329.5 million - 335.5 million.

------

Regarding the fourth quarter, Luis von Ahn remarked, "As we said in our third quarter 2025 shareholder letter, we're prioritizing teaching better and user growth, and we executed on that strategy in the fourth quarter. While I'm delighted with our preliminary fourth quarter metrics, we plan to continue to invest meaningfully in the product, even when it involves near-term tradeoffs. We are doing this because our long-term opportunity is to teach billions of people, and while we've made incredible progress, we remain early in our journey."
