Item 1.01 Entry into a Material Definitive Agreement
As previously disclosed, on November 16, 2021, Duolingo, Inc. (the "Company") entered into an Office Lease Agreement (the "Lease") with 5704 Penn Office, LLC. (the "Landlord"), to lease approximately 38,000 square feet of office space located at Liberty East at 141 South Saint Clair Street, Pittsburgh, Pennsylvania (the "Premises") for additional office space. Initial base rent under the Lease was approximately $148,000 per month, with an increase by approximately 2.0% per annum. The initial term of the Lease began on November 16, 2021 and provided for the Company to commence paying rent thereunder on the later of (i) the date the Landlord delivered the Premises to the Company with the Landlord's work having been substantially completed or (ii) May 1, 2022 (the "Rent Commencement Date"), with the lease term expiring on the 13
th
anniversary of the Rent Commencement Date. The Company later entered into a Commencement Date Agreement, in the form attached to the Lease, providing for a Rent Commencement Date of June 15, 2022 and an expiration date of June 15, 2035.
On March 4, 2024, the Company entered into the First Amendment to the Lease (the "First Amendment"), which, among other things, increases the leased square footage by 110,008 square feet to a total of 148,266 square feet beginning on August 1, 2025, with an expiration date of April 30, 2036. Under the First Amendment, the monthly fixed base rent (as defined in the First Amendment) for the initial square footage increases to approximately $188,000 per month for the period commencing June 16, 2035 and ending April 30, 2036. The initial base rent of the additional square footage is approximately $394,000 per month and will increase by approximately 2.0% per annum, with the exception of the third and fifth years, which have increases of approximately 9% related to additional parking access.
Under the terms of the First Amendment, the Landlord will provide the Company with an improvement allowance of up to approximately $6.6 million for costs relating to the design, permitting, and construction of improvements to the Premise.
The foregoing summary of the First Amendment is only a summary of the material terms of the First Amendment, does not purport to be a complete description of the rights and obligations of the parties thereunder, and is qualified in its entirety by reference to the full text of the First Amendment, a copy of which will be filed as an exhibit to the Company's Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024.
