In the proxy statement of Graham Corporation (the “Company”) dated June 22, 2017, the Company disclosed that during fiscal year 2017, one director, Gerard T. Mazurkiewicz, failed to attend at least 75% of the aggregate of (1) the total number of meetings of the Company’s Board of Directors (the “Board”) and (2) the total number of meetings of all committees of the Board on which he served. This was the result of Mr. Mazurkiewicz being unable to attend a single day of Board and committee meetings due to illness, causing him to miss the Board meeting and the meetings of the Audit Committee and the Nominating & Corporate Governance Committee that were held on that day. Except for this absence on a single day of meetings, Mr. Mazurkiewicz attended 100% of the meetings of the Board and the committees on which he served during fiscal year 2017.
