Quarterly Revenues Increase 8% Year Over Year

Earnings Per Share Increase to $0.21

HUNT VALLEY, MD, October 23, 2017—TESSCO TECHNOLOGIES INCORPORATED (NASDAQ: TESS), today reported financial results for its second quarter of fiscal 2018, ended September 24, 2017.

Second-Quarter Highlights:

* EBITDA per diluted share and EBITDA (on which EBITDA per diluted share is based) are Non-GAAP financial measures. Non-GAAP financial measures indicated by an asterisk (*) either in the above chart or in the text of this press release are so indicated as a means to direct the reader to the discussion of Non-GAAP Information below and the reconciliation of Non-GAAP to GAAP results included as an exhibit to this press release.  

Second-Quarter Revenue by Market:

“We executed on our profitability initiatives during the second quarter, extending our recent trend of year-over-year top- and bottom-line growth,” said Murray Wright, President and Chief Executive Officer. “Revenue grew in all commercial markets, including a 48% year-over-year increase in revenue from the carrier market. The

improved bottom-line performance was a direct result of the revenue growth we are seeing in the business, combined with our effective expense management. We believe these improved bottom-line results are an indication of the operating leverage potential the company possesses. 

“We are executing on our strategic plan and are focused on balancing the implementation of our go-to-market strategy with improved operating efficiency,” Wright continued. “We are leveraging a strong value proposition and adding talent to our already dynamic team to further accelerate results. There is strong momentum in our business, and we look forward to building on our recent track record of sales growth and improved profitability. Our focus on improving the customer experience is enabling us to generate new opportunities, and we are encouraged about our ability to drive success in the quarters to come.”

Second-Quarter Fiscal 2018 Financial Results

For the fiscal 2018 second quarter, revenues totaled $145.1 million, compared with $134.6 million for the second quarter of fiscal 2017. The increase in revenues as compared to the prior-year period resulted primarily from a significant increase in sales to the public carrier ecosystem, although sales in all commercial markets grew.

Gross profit was $29.9 million for the second quarter of fiscal 2018, up from $28.8 million for the same quarter of fiscal 2017. The year-over-year increase in gross profit was primarily the result of higher overall sales. Gross margin was 20.6% of revenue for the second quarter of fiscal 2018, compared with 21.4% for last year’s second quarter. The decrease in gross margin was largely due to changes in customer and product mix, including the increase in lower-margin sales to the public carrier market.

Selling, general and administrative (SG&A) expenses were $26.7 million for the second quarter of fiscal 2018, flat compared with the same quarter of the prior year, despite normal variable cost increases in the current year quarter, associated with the 8% revenue growth.  

Net income and earnings per share (EPS) were $1.8 million and $0.21, respectively, for the second quarter of fiscal 2018, compared with net income and EPS of $1.0 million and $0.12, respectively, for the prior-year second quarter.

Balance Sheet and Cash Flows

Increasing sales to the Company’s public carrier customers at times require significant investments in inventory. Therefore, increasing the Company’s positioning and market share with these customers requires working capital investment. During the second quarter, sales to public carrier customers increased 48% from last year’s second quarter and year-to-date sales in this market have increased 54% over last year. Accordingly, during this fiscal year, the Company experienced increases in inventory and accounts receivable and a corresponding decrease in its cash position, as well as increased borrowings on its line of credit. As of September 24, 2017, cash and equivalents totaled $0.2 million, and the outstanding balance on the Company’s line of credit was $13.3 million. Cash flow used in operations was $16.8 million during the first half of the 2018 fiscal year, primarily due to increases in inventory and accounts receivable. Inventory increased by $9.2 million during the first half of the fiscal year to $73.2 million as of September 24, 2017. Trade accounts receivable increased $28.2 million in the first six months of the year to $92.9 million.

On October 19, 2017, the Company expanded its previously existing secured line of credit facility with SunTrust Bank, as Administrative Agent and a lender, in an effort to ensure the ability to make increased investments in its business. The expanded credit facility is evidenced by an Amended and Restated Credit Agreement and other ancillary documents, which provide for a borrowing limit increase from $35 million to up to $75 million, on terms generally consistent with those previously existing. The applicable borrowing base has, however, been expanded

to include not only eligible receivables but also eligible inventory. The Company believes that the expanded credit facility will allow for increased access to cash and will facilitate the Company's efforts to make appropriate investments as needed to continue to grow. 

Cash Dividend 

The Company’s Board of Directors has declared a quarterly cash dividend of $0.20 per common share payable on November 22, 2017 to common stockholders of record on November 8, 2017. Any future declaration of dividends, and the establishment of record and payment dates, is subject to future determinations of the Board of Directors.

The Company is not providing earnings guidance at this time for fiscal 2018.

Non-GAAP Information 

EBITDA and EBITDA per diluted share are measures used by management to evaluate the Company’s ongoing operations, and to provide a general indicator of the Company's operating cash flow (in conjunction with a cash flow statement which also includes among other items, changes in working capital and the effect of non-cash charges). EBITDA is defined as income from operations, plus interest expense, net of interest income, provision for income taxes, and depreciation and amortization.  EBITDA per diluted share is defined as EBITDA divided by Tessco’s diluted weighted average shares outstanding.

Management believes EBITDA and EBITDA per share are useful to investors because they are frequently used by securities analysts, investors and other interested parties in the evaluation of companies. Because not all companies use identical calculations, the Company’s presentation of these Non-GAAP measures may not be comparable to other similarly titled measures of other companies. Neither EBITDA nor EBITDA per diluted share is a recognized term under GAAP, and EBITDA does not purport to be an alternative to net income as a measure of operating performance or to cash flows from operating activities as a measure of liquidity. Additionally, neither EBITDA nor EBITDA per diluted share is intended to be a measure of free cash flow for management's discretionary use, as certain cash requirements, such as interest payments, tax payments and debt service requirements, are not reflected.

A reconciliation of Non-GAAP to GAAP results is included as an exhibit to this release.
