CLEVELAND, November 2, 2017 -- Parker Hannifin Corporation (NYSE: PH), the global leader in motion and control technologies, today reported results for the fiscal 2018 first quarter ended September 30, 2017. Fiscal 2018 first quarter sales increased 23% to $3.36 billion compared with $2.74 billion in the prior year quarter. Net income increased 36% to $285.5 million compared with $210.2 million in the prior year quarter. Fiscal 2018 first quarter earnings per share increased 36% to $2.10, compared with $1.55 in the fiscal 2017 first quarter. During the quarter, the company recognized a lower effective tax rate compared with the first quarter of fiscal 2017, due primarily to tax benefits related to stock option activity, resulting in a favorable impact to earnings of $0.12 per share. Earnings per share increased 40% to $2.24 when adjusted for business realignment expenses, CLARCOR costs to achieve and a loss related to the sale of an investment, compared with earnings per share of $1.61 in the prior year quarter, which was adjusted for business realignment expenses. Fiscal year to date, net cash provided by operating activities was $239.0 million or 7.1% of sales, compared with $113.9 million or 4.2% of sales in the prior year period. Operating cash to sales was 12.2% in the prior year period excluding discretionary pension contributions.

Diversified Industrial Segment: North American first quarter sales increased 37% to $1.6 billion, and operating income increased 28% to $256.0 million compared with $200.6 million in the same period a year ago. International first quarter sales increased 22% to $1.2 billion, and operating income increased 40% to $191.8 million compared with $137.2 million in the same period a year ago.

For the fiscal year ending June 30, 2018, the company has increased guidance for earnings from continuing operations to the range of $8.45 to $9.05 per share, or $9.10 to $9.70 per share on an adjusted basis. Fiscal year 2018 guidance is adjusted on a pre-tax basis for the reported loss on investment of approximately $14 million, expected business realignment expenses of approximately $58 million and CLARCOR costs to achieve of approximately $52 million.

Orders provide near-term perspective on the company's outlook, particularly when viewed in the context of prior and future quarterly order rates. However, orders are not in themselves an indication of future performance. All comparisons are at constant currency exchange rates, with the prior year restated to the current-year rates. All exclude acquisitions until they can be reflected in both the numerator and denominator. Aerospace comparisons are rolling 12-month average computations. The total Parker orders number is derived from a weighted average of the year-over-year quarterly % change in orders for Diversified Industrial North America and Diversified Industrial International, and the year-over-year 12-month rolling average of orders for the Aerospace Systems Segment.

This press release contains references to (a) earnings per share and segment operating margins without the effect of business realignment charges, CLARCOR costs to achieve and a loss related to the sale of an investment; (b) the effect of business realignment charges, CLARCOR costs to achieve and a loss related to the sale of an investment on forecasted earnings from continuing operations per share; (c) and cash flows from operations without the effect of discretionary pension contributions. The effects of business realignment charges, CLARCOR costs to achieve, loss related to sale of investment and discretionary pension contributions are removed to allow investors and the company to meaningfully evaluate changes in earnings per share, segment operating margins and cash flows from operations on a comparable basis from period to period.

Forward-looking statements contained in this and other written and oral reports are made based on known events and circumstances at the time of release, and as such, are subject in the future to unforeseen uncertainties and risks.

It is possible that the future performance and earnings projections of the company, including its individual segments, may differ materially from current expectations, depending on economic conditions within its mobile, industrial and aerospace markets, and the company's ability to maintain and achieve anticipated benefits associated with announced realignment activities, strategic initiatives to improve operating margins, actions taken to combat the effects of the current economic environment, and growth, innovation and global diversification initiatives.

complete such activities and realize the anticipated cost savings from such activities; ability to implement successfully capital allocation initiatives, including timing, price and execution of share repurchases; availability, limitations or cost increases of raw materials, component products and/or commodities that cannot be recovered in product pricing; ability to manage costs related to insurance and employee retirement and health care benefits; compliance costs associated with environmental laws and regulations; potential labor disruptions; threats associated with and efforts to combat terrorism and cyber-security risks; uncertainties surrounding the ultimate resolution of outstanding legal proceedings, including the outcome of any appeals; competitive market conditions and resulting effects on sales and pricing; and global economic factors, including manufacturing activity, air travel trends, currency exchange rates, difficulties entering new markets and general economic conditions such as inflation, deflation, interest rates and credit availability.
