ROBBINS & MYERS REPORTS
FIRST QUARTER FISCAL 2006 RESULTS, REALIGNS SEGMENTS
AND TAKES A NON-CASH GOODWILL IMPAIRMENT CHARGE

DAYTON, OHIO, December 20, 2005 . . . Robbins & Myers, Inc. (NYSE:RBN) announced today its financial results for first quarter of fiscal 2006, ended November 30, 2005. For the first quarter of fiscal 2006, the Company reported income of $0.06 per share before special charges, slightly ahead of previous guidance of $0.00 to $0.05 per diluted share. Beginning with the first quarter 2006, the Company is reporting under its previously announced realigned segments, Fluid Management, Process Solutions and Romaco. As part of the process of realigning the business segments, the Company recorded an estimated non-cash goodwill impairment charge of $2.04 per share related to the Romaco business and restructuring expenses of $0.04 per share, resulting in a net loss for the first quarter of $2.02 per share.

Fiscal 2006 first quarter sales of $139.0 million were up by $6.5 million compared with the first quarter of fiscal 2005. Loss before interest and taxes was $25.3 million in the first quarter of fiscal 2006 versus a loss of $0.1 million last year. The non-cash goodwill impairment charge of $30.0 million and restructuring costs of $0.8 million in the recent quarter are $25.9 million higher than restructuring charges were in the first quarter of fiscal 2005. The fiscal 2006 first quarter net loss was $29.7 million ($2.02 loss per diluted share) versus a net loss of $0.9 million ($0.06 loss per diluted share) in the comparable prior year period.

Peter C. Wallace, President and Chief Executive Officer of Robbins & Myers, Inc., stated, “This is the first time we are reporting our results under the new business segment alignment of Fluid Management, Process Solutions and Romaco. We have organized our business around these segments as we transition to become a market driven operating company.”

The Fluid Management segment (R & M Energy Systems and Moyno product lines) experienced a 16.7% sales increase driven primarily by strong demand for oilfield equipment products due to high levels of oil and gas exploration and recovery activity. EBIT for Fluid Management was $11.5 million, up 27.4% over the first quarter of the prior year. The outlook for the Fluid Management segment remains positive for 2006 due to strong demand in the energy market, the high price of oil and gas and anticipated increases in 2006 maintenance capital spending.

First quarter fiscal 2006 revenue of the Process Solutions segment (Pfaudler, Cheminear & Edon product lines) decreased by 6.5% to $53.1 million from $56.8 million in the prior year. Approximately $2.5 million of the year over year sales decline relates to the sale of the Edlon Lined Pipe and Fittings business sold in the fourth quarter of fiscal 2005. EBIT was higher in the current year quarter than in the prior year due to lower restructuring charges for the first quarter of 2006 and cost savings being realized from prior year restructuring programs. The outlook for Process Solutions reflects gradual improvement in the chemical processing industry.

The Romaco segment’s first quarter sales of $33.4 million are 8.7% higher than in the comparable prior year quarter. EBIT declined during the first quarter 2006 on a year-over-year basis due to the non-cash goodwill impairment of $30.0 million and restructuring charges of $0.5 million. Excluding special charges profitability was constant on a year over year basis. The outlook for 2006 remains soft due to continued weakness in the pharmaceutical market place.

Mr. Wallace further commented on the first quarter 2006 results, “Our first quarter performance was substantially in line with expectations. The Fluid Management business should continue to run at record levels for the remainder of our 2006 year. Our Process Solutions business will benefit from a more active chemical processing end-market, along with cost improvements that have been and will be made in the business. The Romaco business continues to be impacted by the restructuring and consolidation efforts of the large Pharmaceutical companies.”

Concerning the possible sale of Romaco, Mr. Wallace stated, “We are currently in discussions with interested firms for various parts of Romaco. We anticipate these discussions will be finalized by the end of our second fiscal quarter 2006 and we will make the appropriate announcements at that time. As part of the portfolio review we have realigned the business segments in 2006 to become a more market driven organization that will deliver better performance as we share resources and leverage our strength. As a result of this business realignment, and the ongoing Romaco discussions we have concluded that there is goodwill impairment. We have recorded a $30.0 million non-cash write down of goodwill based on our preliminary estimates at this time. The Company will commission an appraisal of the Romaco business to determine the final impairment charge.”

Mr. Wallace commented further, “We are beginning to see some benefits from the realignment of product lines. Manufacturing units are working together to manage production levels, reduce overtime, and improve asset utilization. We are also sharing information across the businesses to leverage our strengths with specific industries and customers. Our earnings guidance for the

year is $0.75-$0.90 per share before special items. Earnings for the second quarter should be in the range of $0.12 — $0.17 per share before special items.”

In this release the Company refers to various non-GAAP measures. Earnings and earnings per share excluding special items are non-GAAP financial measures. The Company believes these measures are helpful to investors in assessing the Company’s ongoing performance of its underlying businesses before the impact of special items on its financial performance. In addition, these non-GAAP measures provide a comparison to our previously announced earnings guidance which excluded these special items. Earnings and earnings per share before special items reconcile to earnings presented according to GAAP as follows:
