LEADING INDEPENDENT PROXY ADVISOR ISS AGREES – SHAREHOLDERS SHOULD VOTE FOR ALL OF HARLEY-DAVIDSON’S DIRECTOR NOMINEES This is a critical juncture in Harley-Davidson’s history, and our Board is working tirelessly to protect the Company’s legacy and choose the Company’s next leader. Don’t just take our word for it – Institutional Shareholder Services (ISS), a leading independent proxy advisory firm, has also recommended that shareholders vote “FOR ALL” of Harley-Davidson’s highly qualified Director nominees. The quotes1 that appear below from a report ISS published on May 5, 2025, demonstrate why we believe shareholders should support Harley-Davidson and reject H Partners’ harmful campaign: HARLEY-DAVIDSON H PARTNERS ISS VOTE RECOMMENDATION: — Vote “FOR ALL” of Harley-Davidson’s Director nominees — H Partners “has not presented a compelling case for change” ISS PERSPECTIVES ON HARLEY-DAVIDSON’S PERFORMANCE AND GOVERNANCE ISS PERSPECTIVES ON H PARTNERS’ CAMPAIGN A fit-for-purpose Board with a track record of protecting shareholders’ best interests An opportunistic hedge fund whose misleading campaign is about getting its own way, not protecting shareholders H Partners’ campaign is undermining the Board’s process to attract the best CEO. “ [D]espite the dissident’s argument that there is a sense of urgency, the distraction of this campaign has almost certainly set the [CEO search] process back. This only reinforces the board’s conclusion that this campaign is a reaction, rather than a measured response.” Harley-Davidson’s strategy is working. “ The bigger picture is that the strategy introduced by [CEO] Zeitz has had a positive impact on the trajectory of HOG, which had lost considerable ground when he took over as interim CEO.” “ HOG has kept pace with peers. This is significant, as HOG dramatically underperformed peers for several years prior to introduction of the Hardwire strategy.” H Partners’ campaign is about getting its own way, not protecting shareholders. “ The facts suggest that when the dissident’s preferred candidate was not selected, the dissident reacted by vacating the board and launching this vote no campaign in an attempt to establish a path to its desired outcome in the CEO search.” The Directors targeted by H Partners’ campaign are critical to the CEO search process. “ [T]he criticisms levied by the dissident against Zeitz as CEO are overstated. [...] [I]t appears that his time in the role has been more positive than negative, which makes it hard to argue that his vote on a successor is worthless.”
