* Reconciliations of non-GAAP financial measures to the nearest GAAP measure are included in the Company’s financial tables accompanying this CFO Commentary.

Revenue

Revenue of $322.9 million was up by 3.9% from a year ago. However, this quarter includes a partial month of activity (approximately 16 days) for recently acquired CENTRIA, which produced revenue during that time of $8.5 million. The performance of our three operating segments was as follows:

Gross Margin

Gross profit increased to $72.1 million, up $12.9 million from last year’s first quarter. Our investments to improve our manufacturing responsiveness and focus on value oriented commercial discipline are beginning to be reflected in our improving gross margins.

Gross Margin Reconciliation: Q1’14 to Q1’15 (19.1% to 22.3%, up 320 basis points)
[note: point attributions are approximate]

ESG&A Expenses

ESG&A expenses were $62.9 million, up $1.5 million from prior year first quarter. ESG&A expenses as a percent of revenues decreased from 19.8% last year to 19.5% in the current quarter. The change in ESG&A expenses over the prior year is attributable primarily to the following:

Income Tax Provision

Our effective income tax benefit rate was unusually high at 60.4% due to the enactment of the Tax Increase Prevention Act, signed in December 2014, which resulted in a discrete benefit recognized during the current period.

*Adjusted EBITDA

*Adjusted EBITDA increased $11.6 million from $8.0 million last year to $19.6 million in the current quarter. The increase in Adjusted EBITDA is attributable to the following:

Working Capital

Our average days sales outstanding for the quarter improved to 35.5 days, compared to 36.9 days in the prior year same period. Our average days in inventory outstanding increased to 50.8 days, compared to 49.1 days in the prior year. And finally, our average days in payables outstanding declined to 32.5 days compared to 35.1 days from the same period of the prior year.

Q2 2015 Outlook

The following are our current expectations for certain financial items for our second fiscal quarter of 2015, which will include the activities of CENTRIA for the full quarter.

ESG&A Expenses

We expect our ESG&A expenses to range between $74 million and $77 million. This amount will include the full quarter of activity for CENTRIA, which was acquired in January, 2015.

Intangible asset amortization

We expect our intangible asset amortization to range between $4.0 million and $4.5 million. This quarterly estimate includes approximately $2 million for amortization of short lived assets related to the CENTRIA acquisition which will continue through the fourth quarter of fiscal 2015. For comparison, total intangible amortization expense in the second quarter of 2014 was only $1.0 million.

Interest Expense

We expect our interest expense, related to our new $250 million 8.25% Senior Notes, our Term Loan Facility, amortization of deferred financing costs and costs from our ABL Facility, to range between $8.4 million and $8.9 million.

Effective Tax Rate

We expect our tax rate for the upcoming quarter to range between 35% and 38%. However, we continue to expect volatility in our quarterly tax rate as slight changes in earnings will have an outsized impact on the effective tax rate given the seasonal variation in earning levels that typically occur. Our quarterly effective tax rate percentage can and has varied significantly from expectations as a result.

Diluted Shares

We expect our weighted average diluted common share count used in calculating our earnings per share to be approximately 73.2 million for the upcoming quarter and 75.8 million for fiscal 2015. This compares to the 73.0 million shares used in the calculation of diluted EPS for the first quarter of 2015. The variation in the share count is driven by the inclusion or exclusion of common stock equivalents in the EPS calculation for each period, which depends on whether they are dilutive or antidilutive to the calculation in that period.

Balance Sheet and Cash Flow Items

We expect our total capital expenditures in fiscal 2015 to range between $26 million and $32 million with the inclusion of CENTRIA.
