ROBBINS & MYERS ANNOUNCES THIRD QUARTER 2012 RESULTS AND

DIVIDEND

Strong Cash Flow, Share Repurchase Announced, $147 million of Cash on Hand

HOUSTON, TEXAS, June 26, 2012…Robbins & Myers, Inc. (NYSE: RBN) today reported diluted net earnings per share from continuing operations (DEPS) of $1.02 for its fiscal third quarter ended May 31, 2012. These results included favorable benefits of $0.07 from tax accrual adjustments, along with benefits from a legal settlement that accounted for $0.03 of the earnings. This compares with $0.41 from continuing operations in the prior year third quarter, or $0.53 after adjusting for one-time charges relating to the acquisition of T-3 Energy Services, Inc. (T-3). The prior year results also include a tax charge of $0.15. Excluding the impact of these items DEPS was $0.92 compared with $0.68 in the prior year period, an increase of 35%.

Consolidated sales were $266 million in the third quarter of 2012 as compared with $237 million in the third quarter of 2011. Excluding the impact of currency translation sales grew $34 million, or 14%, over the prior year period. The Company reported third quarter 2012 orders of $286 million, an increase of 10% over the prior year period excluding the impact of currency translation. Third quarter ending backlog increased to $315 million, up from $301 million at the end of the second quarter and $248 million at the end of the third quarter of the prior year. Each of Robbins & Myers’ business platforms achieved solid growth.

Third quarter 2012 earnings before interest and taxes (EBIT) were $62 million, including a $2 million favorable legal settlement, and significantly higher than the adjusted EBIT of $47 million reported in the third quarter of 2011. EBIT margin of 23.2% in the third quarter of 2012 was substantially higher than the 19.8% adjusted EBIT margin in the prior year period, as a result of improved profitability in each business platform and 70 basis points from the legal settlement. The Company reported EBITDA of $69 million in the third quarter of 2012, compared with adjusted EBITDA of $54 million in the third quarter of fiscal 2011. Each business segment showed improved profitability as a result of additional volume, and the Process & Flow Control group benefitted from price and cost improvements.

“We are pleased with performance in both of our business segments,” said Peter C. Wallace, President and Chief Executive Officer of Robbins & Myers, Inc. “The Energy Services segment had outstanding operating performance and built backlog despite rig count growth stalling along with declining crude oil prices. This pause in U.S. rig count growth has been offset somewhat by rig intensity as the footage drilled in the U.S. continues to increase. However, our short-term outlook is more cautious due to overall concerns around global economic growth and the impact this has had on crude oil prices. In the Process & Flow Control segment we continue to see stronger demand in the chemical and industrial markets, as evidenced by orders this quarter. We have steadily improved operating performance in this segment by leveraging incremental

sales volume and recovering margin with a sharper focus on regional pricing opportunities and cost controls.”

Robbins & Myers generated $61 million of cash from operating activities in the third quarter of fiscal 2012 compared with $39 million in the prior year same quarter. The increase was primarily attributable to higher net income from continuing operations in 2012.

Updated Guidance

Based on recent financial performance, Robbins & Myers narrowed its fiscal 2012 DEPS forecast from $3.40-$3.60 to $3.45-$3.55. For the fourth quarter the Company expects to earn $0.90-$1.00, which excludes approximately $0.08 of higher than normal tax cost related to structural tax changes that are expected to benefit future years. Overall, the effective tax rate for all of 2012 is expected to be at a normalized rate slightly below the U.S. statutory rate of 35%.

Third Quarter Results by Segment

All comparisons are made against the comparable year-ago quarterly period unless otherwise stated.

The Company’s Energy Services segment reported orders of $176 million, an increase of $9 million over the prior year period excluding the impact of currency. Sales were $175 million in the third quarter and $32 million over the prior year period, an increase of 22% excluding currency impacts, EBIT was $55 million or 31.7% of sales, which included the favorable legal settlement of $2 million, compared with adjusted EBIT of $44 million or 30.2% of sales in the prior year period. Ending backlog was $172 million, slightly higher than at the end of the second quarter.

The Process & Flow Control segment reported orders increased $19 million over the prior year period to $110 million in this quarter, or 20% excluding currency impacts. The increase was primarily due to improving demand for capital goods in the chemical markets. Sales of $91 million were $2 million, or 2%, higher than the prior year excluding currency impacts. The segment reported $10 million of EBIT in the third quarter of 2012, 10.9% of sales, as compared with $9 million or 9.9% of sales in the prior year period.
