Second-Quarter Revenue by Market:

“We delivered strong top-line growth of 9% in the second quarter, representing the seventh year-over-year revenue increase in the past eight quarters,” said Murray Wright, President and Chief Executive Officer. “Our second-quarter growth was primarily driven by a 45% year-over-year increase in sales to the Public Carrier

ecosystem, where we continue to grow our market share. We are seeing strong results through all four of the Tier 1 carriers, especially with MasTec, AT&T’s largest Turf contractor. We also achieved a 6% increase in the Retail market, where we continue to have strong results with the indirect carrier customers. Finally, while quarterly sales were down slightly in the Integrators and End-User market, we did successfully complete the rollout of a full regionalization model which brings together the former Private Systems, Value-added Reseller and Government markets in one comprehensive sales organization. We believe this strategy positions us well for future success in this market, with better territory alignment, and we have already received positive feedback and incremental opportunities from many of our key suppliers and customers. The enhanced go-to-market strategies that we have been rolling out over the past twelve months and our strong value proposition are resonating well with customers.

“While we achieved 9% revenue growth, our earnings this quarter were impacted by an increase in lower margin Public Carrier sales and higher service costs in the Public Carrier and Retail markets.  Our commitment to serve our project-based and larger retail customers caused us to incur higher freight in, freight out and other operational costs this quarter. This resulted in lower gross margins and increased SG&A expenses.  Despite these increased operational expenses, we are focused on our gross margin improvement initiatives to help offset the pressure from customer mix and freight costs. These initiatives include improved pricing management, improved product mix including growth in both Ventev product lines and our supplier rationalization and profitability programs.  At the same time, we are implementing processes to optimize this rapid growth and drive enhanced earnings.

“Our top-line improvement is the direct result of the sales initiatives we put in place during the past year, and we expect this momentum to continue in the second half of fiscal 2019. As I have said in previous quarters, we expect our growth to result in some variability in quarter-to-quarter earnings. We also continue to expect revenue and earnings growth in fiscal 2019,” concluded Wright.

Second-Quarter 2019 Financial Results

For the fiscal 2019 second quarter, revenues totaled $158.6 million, compared with $145.1 million for the second quarter of fiscal 2018. The increase in revenue was driven by the Company’s Public Carrier and Retail markets.

Gross profit was $31.4 million for the second quarter of fiscal 2019, compared with $29.9 million for the same quarter of fiscal 2018. The 5% increase in second-quarter gross profit year over year was primarily the result of higher total sales. Gross margin was 19.8% of revenue for the second quarter of fiscal 2019, compared with 20.6% in the second-quarter of last year. This decline is primarily due to the larger portion of sales from lower margin carrier market customers as well as increases in freight-in costs related to the growth in project business and expedited international shipments of the Company’s Ventev products to meet customer launch schedules.

Selling, general and administrative (SG&A) expenses increased 11% to $29.5 million, due primarily to freight out costs, higher reserves for bad debts and higher technology costs to support the business.

Net income and earnings per share (EPS) were $1.2 million and $0.14, respectively, for the second quarter of fiscal 2019, compared with $1.8 million, or $0.21 per share, for the prior-year second quarter.

Cash Dividend

The Company’s Board of Directors has declared a quarterly cash dividend of $0.20 per common share payable on November 28, 2018 to common stockholders of record on November 14, 2018. Any future declaration of dividends, and the establishment of record and payment dates, is subject to future determinations of the Board of Directors.

Business Outlook

The Company currently anticipates year-over-year growth in revenue and profitability in fiscal 2019. While the Company does expect growth in the Public Carrier ecosystem, it also expects this to result in a lower overall year-over-year gross margin, given the lower-margin nature of many of these large carrier relationships.

Forecasting future results or trends is inherently difficult for any business, and actual results or trends may differ materially from those forecasted. The nature of the business is that Tessco typically ships products within several days after booking orders, which makes it more difficult to forecast future results. The Business Outlook published in this press release reflects only the Company’s current best estimate and it assumes no obligation to update the information contained in this press release, including the Business Outlook, at any time.

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.
