OSHKOSH CORPORATION REPORTS FISCAL 2017
THIRD QUARTER RESULTS

Increases Fiscal 2017 Estimated EPS Range

Declares Quarterly Cash Dividend of $0.21 Per Share

OSHKOSH, WI — (August 2, 2017) — Oshkosh Corporation (NYSE: OSK) today reported fiscal 2017 third quarter net income of $128.6 million, or $1.69 per diluted share, compared to $84.2 million, or $1.13 per diluted share, in the third quarter of fiscal 2016. Results for the third quarter of fiscal 2017 included after-tax charges of $11.2 million associated with previously announced restructuring actions in the access equipment segment. Excluding these charges, fiscal 2017 third quarter adjusted(1) net income was $139.8 million, or $1.84 per diluted share. Comparisons in this news release are to the corresponding period of the prior year, unless otherwise noted.

Consolidated net sales in the third quarter of fiscal 2017 were $2.04 billion, an increase of 16.6 percent. All segments reported increased sales, led by the defense segment.

Consolidated operating income increased 44.3 percent to $211.9 million, or 10.4 percent of sales, in the third quarter of fiscal 2017 compared to $146.8 million, or 8.4 percent of sales, in the third quarter of fiscal 2016. Excluding $10.6 million of pre-tax restructuring-related charges in the access equipment segment, adjusted(1) operating income in the third quarter of fiscal 2017 was $222.5 million, or 10.9 percent of sales. The increase in adjusted(1) operating income was primarily the result of higher sales, improved pricing in the fire & emergency segment and improved product mix.

Oshkosh Corporation believes that the non-GAAP measures provide investors a useful comparison of the Company’s performance to prior period results.

“We are pleased to report another quarter of strong performance highlighted by growth in revenue, operating income and earnings per share in our fiscal third quarter,” said Wilson R. Jones, president and chief executive officer of Oshkosh Corporation. “We delivered increased sales in all four segments, driving revenue growth of 16.6 percent and adjusted(1) operating income growth of 51.6 percent. This resulted in adjusted(1) earnings per share of $1.84, greatly exceeding our fiscal 2016 third quarter results.

“This was a strong quarter by many measures of performance and we are proud of the way our team members are executing in this, our 100th year as a company. In particular, our access equipment and fire & emergency segments reported stronger than expected results in the quarter and all of our non-defense segments ended the period with higher year over year backlogs. Additionally, our defense team worked hard to deliver M-ATVs in support of a large international order that extends into the first quarter of fiscal 2018. They are also on track delivering JLTVs to the U.S. Department of Defense that are being driven and tested daily to support the government’s Low Rate Initial Production schedule as the program ramps up over the next several years.

“As a result of our strong performance and positive outlook for the remainder of fiscal 2017, we are increasing our expectations for fiscal 2017 earnings per share to be in a range from $3.33 to $3.43, or $3.80 to $3.90 on an adjusted(1) earnings per share basis. We look forward to delivering strong fiscal 2017 performance and believe we are well positioned for fiscal 2018, as evidenced by our strong backlogs, positive sentiment in our markets and the strength of our people,” said Jones.

Factors affecting third quarter results for the Company’s business segments included:

Access Equipment — Access equipment segment net sales increased 2.9 percent to $980.2 million in the third quarter of fiscal 2017. The increase in sales was primarily due to higher aerial work platform sales, offset in part by lower telehandler sales.

Access equipment segment operating income increased 6.6 percent to $130.2 million, or 13.3 percent of sales, in the third quarter of fiscal 2017 compared to $122.1 million, or 12.8 percent of sales, in the third quarter of fiscal 2016. Excluding restructuring-related charges, access equipment segment adjusted(1) operating income in the third quarter of fiscal 2017 increased 15.3 percent to $140.8 million, or 14.4 percent of sales. The increase in adjusted(1) operating income was primarily due to the impact of higher sales volume, a more favorable product mix and more efficient material usage.

Defense — Defense segment net sales for the third quarter of fiscal 2017 increased 82.6 percent to $482.7 million. The increase in sales was primarily due to international Mine Resistant Ambush Protected-All Terrain Vehicle sales and the ramp-up of sales to the U.S. government under the Joint Light Tactical Vehicle program, offset in part by lower sales to the U.S. government under the Family of Medium Tactical Vehicles program.

Defense segment operating income increased 226.7 percent to $62.4 million, or 12.9 percent of sales, in the third quarter of fiscal 2017 compared to $19.1 million, or 7.2 percent of sales, in the third quarter of fiscal 2016. The increase in operating income was largely due to the impact of higher sales volume.

Fire & Emergency — Fire & emergency segment net sales for the third quarter of fiscal 2017 increased 13.8 percent to $282.9 million. Sales in the third quarter of fiscal 2017 benefited from higher domestic fire apparatus deliveries as a result of increased production rates, the timing of international fire apparatus deliveries and improved pricing.

Fire & emergency segment operating income increased 56.3 percent to $30.8 million, or 10.9 percent of sales, in the third quarter of fiscal 2017 compared to $19.7 million, or 7.9 percent of sales, in the third quarter of fiscal 2016. The increase in operating income was primarily a result of improved pricing and the impact of higher sales volume.

Commercial — Commercial segment net sales increased 2.5 percent to $295.2 million in the third quarter of fiscal 2017. The increase in sales was primarily due to higher refuse collection vehicle unit volume.

Commercial segment operating income decreased 9.2 percent to $21.6 million, or 7.3 percent of sales, in the third quarter of fiscal 2017 compared to $23.8 million, or 8.3 percent of sales, in the third quarter of fiscal 2016. The decrease in operating income was primarily a result of operational inefficiencies associated with changes in production volumes.

Corporate — Corporate operating costs decreased $4.8 million in the third quarter of fiscal 2017 to $33.1 million due primarily to improved operating results related to a corporate-led manufacturing facility, which incurred higher start-up costs during the third quarter of fiscal 2016.

Interest Expense Net of Interest Income — Interest expense net of interest income decreased $1.4 million to $13.9 million in the third quarter of fiscal 2017.

Provision for Income Taxes — The Company recorded income tax expense of $70.1 million in the third quarter of fiscal 2017, or 35.3 percent of pre-tax income, compared to $48.4 million, or 36.6 percent of pre-tax income, in the third quarter of fiscal 2016. Excluding the impact of restructuring-related charges, adjusted(1) income tax expense in the third quarter of fiscal 2017 was $69.5 million, or 33.2 percent of adjusted(1) pre-tax income. The Company recorded $3.9 million of discrete tax benefits in the third quarter of fiscal 2017. The Company recorded a year-to-date adjustment in the third quarter of fiscal 2016 to increase tax expense as a result of a higher estimated mix of domestic income versus lower-tax rate foreign income.

Nine-month Results

The Company reported net sales for the first nine months of fiscal 2017 of $4.87 billion and net income of $192.1 million, or $2.54 per diluted share. This compares with net sales of $4.52 billion and net income of $154.9 million, or $2.08 per diluted share, in the first nine months of the prior year. Excluding $24.9 million of after-tax restructuring-related charges in the access equipment segment, adjusted(1) net income for the first nine months of fiscal 2017 was $217.0 million, or $2.87 per diluted share. Improved performance in the defense, fire & emergency and access equipment segments and lower start-up costs for a corporate-led manufacturing facility were partially offset by lower results in the commercial segment and higher incentive compensation expense.

The Company also increased its fiscal 2017 adjusted(1) diluted earnings per share estimate range to $3.80 to $3.90 on adjusted(1) operating income of $480 million to $490 million.

Non-GAAP Financial Measures

The Company reports its financial results in accordance with generally accepted accounting principles in the United States of America (GAAP).

The Company believes excluding the impact of these items is useful to investors in comparing the Company’s performance to prior period results. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s results prepared in accordance with GAAP. The table below presents a reconciliation of the Company’s presented non-GAAP measures to the most directly comparable GAAP measures (in millions, except per share amounts):
