Attn: Mr. Scott A. Buckhout, President and Chief Executive Officer

VIA email and UPS

Dear Members of the Board of Directors:

We are extremely disappointed by the CIRCOR International, Inc. (“CIRCOR”) Board of Director’s rejection of our proposal to acquire CIRCOR as communicated in our letter to the Board dated April 30, 2019. CIRCOR’s refusal to engage with us continues a pattern of rejections of private acquisition proposals we have made in the past. Our all-cash proposal provides an attractive premium to CIRCOR shareholders, and eliminates the uncertainty associated with CIRCOR’s ability to execute its standalone business plan. In light of the Board’s intransigence, we will be making our proposal public so that CIRCOR shareholders can evaluate the merits of our proposal and make their views known to the CIRCOR Board.

We urge the CIRCOR Board to engage with us on a transaction that is clearly in the best interests of your shareholders, consistent with the Board’s fiduciary duties. We stand ready to complete confirmatory due diligence expeditiously and are confident this transaction can be completed quickly.

Sincerely,

/s/ Max H. Mitchell

Max H. Mitchell

President and Chief Executive Officer
