Rudolph Technologies Completes Existing Stock Repurchase Plan and Authorizes an Additional $40 Million Share Repurchase Plan

Rudolph Technologies repurchased $14.3 million of stock in the 2018 fourth quarter.

Wilmington, Mass. (October 29, 2018)—Rudolph Technologies, Inc. (NYSE: RTEC) today announced that it has completed its 2015 stock repurchase plan of three million shares by purchasing the 711,000 shares remaining in the plan. For these purchases, the average price paid per share was $20.80 resulting in a total of $14.3 million in repurchase cost. On October 23, 2018, Rudolph’s Board of Directors authorized the repurchase of up to an additional $40 million of stock.

Mike Plisinski, CEO, commented, "Rudolph’s share repurchase activity, coupled with the new $40 million share repurchase authorization, reflects the Company’s confidence in our short and long term growth initiatives and the belief that recent stock prices do not properly value those initiatives.  Consistent with our capital allocation strategy we will leverage our strong balance sheet and positive cash flows to take advantage of under-valued market conditions to buy back our shares while maintaining the flexibility for investments in other growth initiatives.”

The new authorization does not obligate Rudolph Technologies to repurchase any particular amount of common stock during any period and the program may be modified or suspended at any time at the Company's discretion. Stock repurchases may be made from time to time and the actual amount repurchased will depend on a variety of factors including market conditions.
