Business Segment Information

6 Months Ended

Mar. 31, 2019

After announcing the planned divestiture of our Solar segment (see Note 4), we conducted an evaluation of our organizational structure. Beginning with the second quarter of fiscal 2019, we made changes to our reportable segments. Prior period amounts have been revised to conform to the current period segment reporting structure. Our three reportable segments are as follows:

Semiconductor – We design, manufacture, sell and service thermal processing equipment and related controls for use by leading semiconductor manufacturers, and in electronics, automotive and other industries.

SiC/LED – We produce consumables and machinery for lapping (fine abrading) and polishing of materials, such as sapphire substrates, optical components, silicon wafers, numerous types of crystal materials, ceramics and metal components. We formerly referred to our SiC/LED segment as “Polishing.”

Automation – We are a leading supplier of solar and semiconductor automation with in-house design and manufacturing capabilities and offer a full array of single wafer transfer tools as well as batch transfer tools and stocker options.

Information concerning our business segments is as follows, in thousands:
