On October 15, 2024, VSE Corporation (the "Company") entered into an Underwriting Agreement (the "Underwriting Agreement") with Jefferies LLC and RBC Capital Markets, LLC, acting as representatives of the several underwriters named therein (the "Underwriters"), pursuant to which the Company agreed to issue and sell (the "Offering") 1,724,137 shares (the "Firm Shares") of the Company's common stock, par value $0.05 per share (the "Common Stock"), at a price to the public of $87.00 per share. The Company also granted the Underwriters a 30-dayoption to purchase up to an additional 258,620 shares of Common Stock offered in the Offering on the same terms and conditions (the "Optional Shares" and, together with the Firm Shares, the "Shares"). On October 16, 2024, the Underwriters informed the Company of their exercise in full of the option to purchase the Optional Shares. The Offering is closing on October 17, 2024.

The Company estimates that the net proceeds from the Offering will be approximately $163.9 million (including the Underwriters' exercise in full of the option to purchase the Optional Shares), after deducting underwriting discounts and commissions and before estimated offering expenses. The Company intends to use net proceeds from the Offering to finance a portion of the cash consideration for its previously announced acquisition of Kellstrom Aerospace Group, Inc. Pending the application of the net proceeds as described herein, the Company may use the net proceeds from the Offering for general corporate purposes, including to invest in short-term, investment grade, interest-bearing securities or to repay outstanding borrowings under the Company's revolving loan facility.

The Underwriting Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Underwriters, including for liabilities under the Securities Act of 1933, as amended, other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement, and may be subject to limitations agreed upon by the contracting parties. Pursuant to the Underwriting Agreement, the Company's executive officers and directors entered into lock-upagreements in substantially the form included as an exhibit to the Underwriting Agreement, providing for a 60-day"lock-up"period with respect to sales of Common Stock, subject to certain exceptions.
