Purchases of Equity Securities by the Issuer and Affiliated Purchasers

The following table provides information regarding purchases of our common stock made by or on behalf of the Company or any “affiliated purchaser” (as defined in Rule 10b-18(a)(3) under the Exchange Act) during the three months ended June 30, 2025 for the periods indicated.

(1)On trade date basis.

(2)On November 4, 2024, the Company's Board of Directors approved the continuation of the Company's $200 million Stock Repurchase Program until November 5, 2025, or until the date the approved dollar amount has been used to repurchase shares. Pursuant to the program, the Company is authorized to repurchase up to $200 million in the aggregate of the Company’s outstanding stock in the open market and/or through privately negotiated transactions at prices not to exceed the Company’s net asset value per share as reported in its most recent financial statements, in accordance with the guidelines specified in Rule 10b-18 of the Exchange Act. The timing, manner, price and amount of any repurchases will be determined by the Company, in its discretion, based upon the evaluation of economic and market conditions, stock price, available cash, applicable legal and regulatory requirements and other factors, and may include purchases pursuant to Rule 10b5-1 of the Exchange Act. The program does not require the Company to repurchase any specific number of shares and there can be no assurance as to the amount of shares repurchased under the program. The program may be suspended, extended, modified or discontinued by the Company at any time, subject to applicable law. Pursuant to the authorization described above, the Company adopted a 10b5-1 plan (the “Company 10b5-1 Plan”). The Company 10b5-1 Plan provides that purchases will be conducted on the open market in accordance with Rules 10b5-1 and 10b-18 under the Exchange Act and will otherwise be subject to applicable law, which may prohibit purchases under certain circumstances. The amount of purchases made under the Company 10b5-1 Plan or otherwise and how much will be purchased at any time is uncertain, dependent on prevailing market prices and trading volumes, all of which we cannot predict. The Company's Stock Repurchase Program was originally approved by the Company's Board of Directors on November 5, 2018 and announced on November 6, 2018.
