TWIN DISC, INC. ANNOUNCES FISCAL 2017

THIRD QUARTER FINANCIAL RESULTS

●    Third Quarter Sales Increased 8.8% to Highest Level in Two Years

●    Gross Profit Percent Improves 630 Basis Points to 29.5% in Third Quarter

●    $1,597,000 of Operating Cash Flow Generated in Third Quarter

●    Six Month Backlog Improved to $49,835,000, a 31% increase from the prior quarter

RACINE, WISCONSIN—May 5, 2017— Twin Disc, Inc. (NASDAQ: TWIN), today reported financial results for the fiscal 2017 third quarter ended March 31, 2017.

Sales for the fiscal 2017 third quarter increased to $45,084,000, from $41,434,000 for the same period last year. Year-to-date, sales were $114,591,000, compared to $123,635,000 for the fiscal 2016 nine months. The increase in 2017 third quarter sales was primarily due to improved demand for the Company’s 8500 series transmission systems from North American pressure pumping customers, and higher sales of aftermarket components, partially offset by softening demand across the Company’s other product categories and geographies.

Commenting on the results, John H. Batten, President and Chief Executive Officer, said, “Significant orders for our 8500 series transmission systems received during the fiscal 2017 third quarter benefited third quarter sales, profitability and backlog. These orders included a 100-unit order from ProFrac Services, which represented one of the largest single transmission system orders the Company has received. Our proactive decision to maintain inventory of oil and gas transmission systems over the past several quarters allowed Twin Disc to quickly begin shipping 8500 series transmissions to customers in the third quarter. In addition, Twin Disc’s focus on efficiently delivering high-quality, high-horsepower transmissions systems to oil and gas customers is a significant competitive advantage and demonstrates Twin Disc’s leadership position in this compelling market. There continues to be a significant underinvestment in fracturing equipment, and we have experienced good demand for aftermarket components. As a result, we are carefully watching the oil and gas market and believe we are well positioned to capitalize on new equipment investments.”

Gross profit for the fiscal 2017 third quarter was 29.5 percent, compared to 23.2 percent in the fiscal 2016 third quarter, and 26.6 percent in the fiscal 2017 second quarter. The 630 basis point increase in gross profit for the fiscal 2017 third quarter compared to the fiscal 2016 third quarter was primarily due to higher shipments of oil and gas transmission systems, increased aftermarket volume, improved operating efficiencies, and a global reduction in fixed manufacturing costs.

Year-to-date, gross margin was 27.4 percent, compared to 23.8 percent for the fiscal 2016 nine months.

For the fiscal 2017 third quarter, marketing, engineering and administrative (ME&A) expenses declined $335,000 to $13,737,000. The 2.4 percent decline in ME&A expenses in the quarter was primarily due to cost reduction actions taken over the past five quarters ($949,000), along with reduced pension expense ($167,000) and reduced spending on corporate development ($136,000). These reductions were partially offset by an increase to incentive compensation expense resulting from the Company’s success in achieving operational performance improvements and fixed cost reductions ($841,000) and stock based compensation ($106,000). Year-to-date, ME&A expenses have declined $5,133,000, or 11.7 percent, to $38,772,000, compared to the same period last fiscal year.

For the third quarter, the Company took a $2,637,000 impairment charge primarily to write down goodwill associated with the Company’s domestic industrial business. This impairment is primarily the result of a lack of any significant market recovery related to these products. This business remains a strategic priority for us, as evidenced by the recent acceleration of new product offerings. We anticipate profitable growth as markets recover and our new products gain market penetration. In addition, the Company recorded restructuring charges of $293,000, compared to restructuring charges of $272,000 in the same period last fiscal year. Year-to-date, Twin Disc had restructuring charges of $1,367,000, compared to $787,000 for the same period last fiscal year. Fiscal 2017’s restructuring activities related to headcount reductions at certain of the Company’s domestic and foreign operations, and are expected to generate approximately $2,400,000 in annualized savings.

The fiscal 2017 nine-month effective tax rate was 34.8 percent, compared to the fiscal 2016 nine-month rate of 51.5 percent. The fiscal 2016 rate was favorably impacted by $2,400,000 of foreign tax credits associated with the repatriation of cash from certain foreign entities.

Net loss attributable to Twin Disc for the fiscal 2017 third quarter was ($1,849,000), or ($0.16) per share, compared to a net loss attributable to Twin Disc of ($963,000), or ($0.09) per share, for the fiscal 2016 third quarter. Year-to-date, the net loss attributable to Twin Disc was ($7,456,000), or ($0.66) per share, compared to a net loss attributable to Twin Disc of ($7,586,000), or ($0.68) per share, for the fiscal 2016 nine months.

Earnings (loss) before interest, taxes, depreciation and amortization (EBITDA)* were ($1,739,000) for the fiscal 2017 third quarter, compared to ($2,732,000) for the fiscal 2016 third quarter. For the fiscal 2017 nine-month period, EBITDA was ($5,744,000) compared to ($8,549,000) for the fiscal 2016 comparable period.

Jeffrey S. Knutson, Vice President – Finance, Chief Financial Officer, Treasurer and Secretary stated, “Higher sales, controlled operating expenses and prudent working capital management helped the company generate $1,597,000 of operating cash flow in the third quarter. Working capital at March 31, 2017, was $84,289,000, compared to $88,904,000, at June 30, 2016, and $92,263,000 at March 25, 2016. At March 31, 2017, the Company had $14,940,000 in cash and $8,977,000 of borrowings drawn under its $40,000,000 revolving credit facility. Year-to-date, we have invested $1,869,000 in capital expenditures and expect to invest approximately $3,000,000 to $4,000,000 in capital expenditures this fiscal year. After a careful review during our third quarter reporting process, we recorded an impairment charge of $2,637,000 for the remaining goodwill associated with our domestic industrial business group.”

Mr. Batten concluded, “Our six-month backlog at March 31, 2017 was $49,835,000 compared to $35,709,000 at June 30, 2016 and $39,952,000 at March 25, 2016. The increased backlog represents additional 8500 series transmissions yet to be shipped and favorable aftermarket trends from customers in the oil and gas, industrial and marine markets. While we are encouraged by our near-term outlook, we have limited demand visibility across many of our markets past the fiscal 2017 fourth quarter. We are closely watching our end markets for sustained signs of improvements and will respond as necessary to capitalize on market trends, while providing customers exceptional products and services. As we finish fiscal 2017, we will focus on expanding production efficiency initiatives, controlling costs, growing market share within all markets, and executing strategies to improve Twin Disc’s market diversification.”
