Fiscal 2019 Full-Year Results

Net sales for fiscal 2019 increased $81.4 million to $1,916.5 million, an increase of 4.4%, compared to $1,835.1 million for fiscal 2018. Net sales increased $46.8 million due to higher sales resulting from the four acquisitions completed by the Company during fiscal 2019 (the "2019 acquisitions"), net of a decrease of $9.4 million resulting from the divestiture of Flexhead. Additionally, net sales increased $24.8 million from higher sales volumes primarily in the Electric Raceway segment. Net sales also increased by $16.8 million due to higher average selling prices resulting from higher market prices for all product categories primarily in the Mechanical Products & Solutions segment.

Gross profit for fiscal 2019 increased $59.1 million to $497.2 million, an increase of 13.5%, compared to $438.1 million for fiscal 2018. Gross margin increased to 25.9% in fiscal 2019 compared to 23.9% in fiscal 2018 due to lower material costs and operating efficiencies.

Selling, general and administrative expenses increased $14.4 million, or 6.4% to $240.7 million for fiscal 2019 compared to $226.3 million for fiscal 2018. The increase was primarily due to additional selling, general and administrative costs of $5.9 million resulting from the 2019 acquisitions and $4.8 million of increased spending on productivity initiatives and growth investments, partially offset by a $2.8 million decrease in stock-based compensation expense driven by higher forfeitures.

Net income increased $2.4 million to $139.1 million for fiscal 2019, as compared to $136.6 million for fiscal 2018. Adjusted net income increased $22.5 million to $172.9 million for fiscal 2019 compared to $150.4 million for fiscal 2018. The increase in both net income and adjusted net income was primarily driven by higher gross profit of $59.1 million, offset by higher selling, general and administrative expense of $14.4 million and higher income tax expense of $15.9 million.

Adjusted EBITDA increased $52.9 million or 19.5%, to $324.4 million for fiscal 2019, as compared to $271.5 million for fiscal 2018. The increase was primarily due to higher gross profit of $59.1 million, partially offset by higher selling, general and administrative expenses attributable to the 2019 acquisitions.

Net income per diluted share on a GAAP basis was $2.83 for fiscal 2019, an increase of $0.35 from fiscal 2018. Adjusted net income per diluted share was $3.62 for fiscal 2019 compared to $2.78 for fiscal 2018.

Net sales for the fourth quarter of 2019 increased to $501.7 million, an increase of 5.1% compared to $477.6 million for the prior-year period, primarily due to higher sales volume of $40.0 million within both the Electrical Raceway and Mechanical Products and Solutions segments and higher sales of $19.9 million from the 2019 acquisitions partially offset by a $34.1 million reduction resulting from lower average selling prices.

Selling, general and administrative expenses increased $11.8 million or 20.7%, to $68.9 million for the fourth quarter of 2019, as compared to $57.1 million for the prior year period.

Net income increased $13.3 million to $46.0 million for the fourth quarter of 2019, as compared to $32.7 million for the prior-year period, due to higher operating income of $19.6 million and higher other income of $8.2 million, offset by higher income tax expense of $14.7 million.

The Company assumes no obligation to update the information contained herein, which speaks only as of the date hereof.

Non-GAAP Financial Information

This press release includes certain financial information, not prepared in accordance with Generally Accepted Accounting Principles in the United States ("GAAP"). Because not all companies calculate non-GAAP financial information identically (or at all), the presentations herein may not be comparable to other similarly titled measures used by other companies. Further, these measures should not be considered substitutes for the performance measures derived in accordance with GAAP. See non-GAAP reconciliations below in this press release for a reconciliation of these measures to the most directly comparable GAAP financial measures.

Adjusted EBITDA and Adjusted EBITDA Margin

We use Adjusted EBITDA and Adjusted EBITDA Margin in evaluating the performance of our business. We use Adjusted EBITDA and Adjusted EBITDA Margin in the preparation of our annual operating budgets and as indicators of business

performance and profitability. We believe Adjusted EBITDA and Adjusted EBITDA Margin allow us to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance.

We define Adjusted EBITDA as net income (loss) before: depreciation and amortization, interest expense, net, loss (gain) on extinguishment of debt, income tax expense (benefit), restructuring and impairments, stock-based compensation, consulting fees, multi-employer pension withdrawal, certain legal matters, transaction costs, gain on sale of a business, gain on sale of joint venture and other items, such as inventory reserves and adjustments and realized or unrealized gain (loss) on foreign currency transactions. We believe Adjusted EBITDA, when presented in conjunction with comparable accounting principles generally accepted in the United States of America ("GAAP") measures, is useful for investors because management uses Adjusted EBITDA in evaluating the performance of our business.

We define Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of Net sales.

Adjusted Net Income and Adjusted Net Income per Share

We use Adjusted net income and Adjusted net income per share in evaluating the performance of our business and profitability. Management believes that these measures provide useful information to investors by offering additional ways of viewing the Company's results that, when reconciled to the corresponding GAAP measure provide an indication of performance and profitability excluding the impact of unusual and or non-cash items. We define Adjusted net income as net income before consulting fees, loss on extinguishment of debt, stock-based compensation, intangible asset amortization, gain on sale of joint venture, certain legal matters and other items. We define Adjusted net income per share as basic and diluted net income per share excluding the per share impact of consulting fees, loss on extinguishment of debt, stock-based compensation, intangible asset amortization, gain on sale of joint venture, certain legal matters and other items. Beginning in March 2018, the Company has excluded the impact of intangible asset amortization from the calculation of Adjusted net income. Adjusted net income prepared for periods prior to March 2018 have also been adjusted to reflect this change.

Leverage Ratio - Net debt/Adjusted EBITDA

We define leverage ratio as the ratio of net debt (total debt less cash and cash equivalents) to Adjusted EBITDA on a trailing twelve-month basis. We believe the leverage ratio is useful to investors as an alternative liquidity measure.

(b) Represents other items, such as inventory reserves and adjustments, release of indemnified uncertain tax positions and the impact of foreign exchange gains or losses.
(c) Beginning in March 2018, the Company has excluded the impact of intangible asset amortization from the calculation of Adjusted net income. Adjusted net income prepared for periods prior to March 2018 have also been adjusted to reflect this change.
(d) The Company calculates basic and diluted net income per common share using the two-class method. Under the two-class method, net earnings are allocated to each class of common stock and participating securities as if all the net earnings for the period had been distributed. The Company's participating securities consist of share-based payment awards that contain a non-forfeitable right to receive dividends and therefore are considered to participate in undistributed earnings with common stockholders. Included within the calculation of net income per diluted share is 3,726 and 2,456 of undistributed earnings allocated to participating securities for fiscal years ended 2019 and 2018. Included within the calculation of net income per diluted share is See Note 10, ''Earnings Per Share'' in our Annual Report on Form 10-K.
(e) Adjusted net income per diluted share is calculated by taking adjusted net income and divided by the weighted-average diluted common shares outstanding.
