Rule 10b5-1 Trading Arrangements

During the three months ended June 30, 2025, no director or officer (as defined in Rule 16a-1(f) under the Exchange Act) of the Company adopted orterminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.

Amendment to June 2025 Credit Agreement

On August 1, 2025, we entered into the Letter Agreement Amendment, which amended the June 2025 Credit Agreement. The Letter Agreement Amendment, among other things, amended (i) the borrowing base by removing model housing units from the borrowing base sublimit, (ii) the financial covenants to (a) decrease the minimum EBITDA to interest expense ratio through December 31, 2026, (b) increase the minimum liquidity amount, (c) decrease the maximum leverage ratio through December 31, 2026 and (d) delete the covenant related to limitations on wholesale sales contracts, (iii) the permitted secured debt basket by increasing the available capacity thereunder and (iv) the restricted payment covenant to restrict the repurchase of shares and payment of dividends through December 31, 2026, subject to the terms and conditions set forth therein. The Credit Agreement otherwise has substantially similar terms and provisions to the June 2025 Credit Agreement. For additional information on the Credit Agreement (including defined terms used in this paragraph), see Note 4, “Notes Payable” to our consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.
