THOR INDUSTRIES INC

Rule 10b5-1 Trading Arrangements

The Company’s Insider Trading Policy permits its directors and officers to trade Company stock under a “Rule 10b5-1 trading arrangement” (as defined in Item 408 of Regulation S-K) that is intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act, subject to compliance with applicable regulations as well as the Company’s Insider Trading Policy and share ownership requirements. The Insider Trading Policy provides that each officer or director Rule 10b5-1 trading arrangement must be entered into in writing during an open trading window and at a time that the officer or director is not aware of material nonpublic information. The Company generally requires that any Rule 10b5-1 trading arrangement adopted by an officer or director must not expire within one year of implementation and is subject to a mandatory cooling-off period requirement.

On January 16, 2024, our Chief Financial Officer, Colleen Zuhl, adopted a Rule 10b5-1 trading arrangement (providing for the sale of up to 9,728 shares of Company common stock) that is intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act. Mrs. Zuhl’s Rule 10b5-1 trading arrangement provides for a mandatory cooling-off period as required by Rule 10b5-1 and is scheduled to expire on January 16, 2025 or such earlier date as of which all of the shares covered by the arrangement have been sold. As of January 31, 2024, Mrs. Zuhl held 118,028 shares of Company common stock not subject to trading under her Rule 10b5-1 trading arrangement.

Except as described above, no director or officer of the Company adopted orterminated a Rule 10b5-1 trading arrangement or “non-Rule 10b5-1 trading arrangement” (as defined in Item 408 of Regulation S-K) during the three months ended January 31, 2024.

PART II – OTHER INFORMATION

The Company is involved in certain litigation arising out of its operations in the normal course of its business, most of which is based upon state “lemon laws,” warranty claims and vehicle accidents (for which the Company carries insurance above a specified self-insured retention or deductible amount). The outcomes of legal proceedings and claims brought against the Company are subject to significant uncertainty. There is significant judgment required in assessing both the probability of an adverse outcome and the determination as to whether an exposure can be reasonably estimated. In management’s opinion, the ultimate disposition of any current legal proceedings or claims against the Company will not have a material effect on the Company’s financial condition, operating results or cash flows. Litigation is, however, inherently uncertain and an adverse outcome from such litigation could have a material effect on the operating results of a particular reporting period.
