Clearfield Reports Fiscal Third Quarter 2017 Results

Volatile Customer Spending Patterns Result in Lower Revenues for the Quarter; 9% Growth in Markets Outside of Alternative Carrier Business in First Nine Months of Fiscal 2017

MINNEAPOLIS, July 27, 2017 (GLOBE NEWSWIRE) -- Clearfield, Inc. (NASDAQ:CLFD), the specialist in fiber management and connectivity platforms for communication service providers, reported results for the fiscal third quarter ended June 30, 2017.

“The results for the fiscal third quarter are lower than our expectations, driven primarily by volatility within several significant customers,” stated Cheri Beranek, President and CEO of Clearfield. “While third quarter revenue is disappointing, we are pleased with the overall progress we’re seeing in the business as a whole, especially at the national carrier level.

“Year-to-date revenues from Clearfield’s traditional service provider markets has grown 9% compared to the same year-ago period. Much of this underlying business is performing according to plan. However, the market we serve continues to experience a lot of noise. This noise manifested itself primarily in the alternative carrier, wireless and cable TV markets.  Though it remains difficult to predict when the demand from these markets will rebound and stabilize, we believe that growth drivers, including next generation cell services driven by 5G and the Internet of Things, will pave the way for these service providers to reignite and scale their optical fiber deployments in the future.

“This noise further masks our success in the expansive Tier 1 market. Our Tier 1 revenue in the first three quarters of this year is nearly double the full year revenue last year. Further, our international revenues year-to-date are 75% above last year’s revenues in the same period.

“Based on the results we’ve achieved year-to-date and our outlook for fiscal Q4, we are revising our revenue guidance for fiscal year 2017 to be consistent with last year’s total revenue of $75 million. Although our revenue projections are less than originally anticipated, we are reiterating our full year guidance for gross profit percent and income from operations. We are also reiterating our guidance for operating expenses, but specifically excluding the impact of the patent infringement lawsuit which was initiated after our operating expense guidance was originally developed.  Clearfield remains dedicated to aggressive but disciplined investments to propel our growth. Through the third quarter ended June 30, 2017, our net income was 4.7% of sales. For the fiscal year ending September 30, 2017, investors can expect similar results.

“We recognize that this reduction in income is disappointing to investors. As we continue to make investments to increase our market share, particularly in the national carrier market, it’s important to keep in mind that while Clearfield has established significant market share in the Tier 3 markets during the first stage of our growth, the market opportunity in front of us as we enter the next stage of our development dwarfs the success we have delivered to date.”

Fiscal Q3 2017 Financial Results
Revenue for the third quarter of fiscal 2017 decreased 9% to $19.6 million from $21.6 million in the same year-ago quarter. The decrease was driven primarily by lower sales to the Company’s alternative carrier, wireless, and cable TV customers, and was partially offset by an increase in sales to the Company’s domestic and international wireline customers, which was supported by strong growth in sales to the Tier 1 market. Excluding revenue from the Company’s alternative carrier business, revenue for the third quarter of fiscal 2017 would have been consistent with the same year-ago quarter.

Gross profit decreased 15% to $7.9 million, or 40.5% of revenue, from $9.3 million, or 43.2% of revenue, in the third fiscal quarter of 2016. The decrease in gross profit was due to decreased volume.  The decrease in gross profit percent was primarily due to a lower percentage of sales associated with optical component solutions, which typically have higher gross margins.

Operating expenses were $6.6 million, an increase of 13% compared to $5.9 million in the same year-ago quarter. Among the operating expense increases were expenses related to additional sales and marketing professionals, enhancements to the Company’s current product line-up and an acceleration of the Company’s investments in product certification testing to successfully compete in the Tier 1 market.

Income from operations decreased 62% to $1.3 million for the third quarter of fiscal 2017 from $3.5 million in the same year-ago quarter. Income tax expense decreased 48% to $593,000 for the third quarter of fiscal 2017 from $1.1 million in the same year-ago quarter. The Company recognized a net tax benefit of $80,000 for the quarter ended June 30, 2016 as a result of the adoption in the fourth quarter of fiscal 2016 of a new accounting pronouncement related to the income tax accounting for stock-based compensation. This net tax benefit and related effects are reflected in the table above and the accompanying financial statements. Net income decreased 66% to $803,000 for the third quarter of fiscal 2017, or $0.06 per diluted share, from $2.4 million, or $0.17 per diluted share, in the same year-ago quarter.

At quarter-end, cash, cash equivalents and investments remained consistent at $42.6 million when compared to the end of the prior quarter. The Company had no debt at quarter end.

During the quarter, the Company repurchased 164,842 shares of its common stock under its stock repurchase program. In April 2017, the Company’s board of directors increased the previously approved stock repurchase program by an additional $4 million to $12 million.

Order backlog (defined as purchase orders received but not yet fulfilled) at June 30, 2017 decreased 26% to $4.4 million from $6.0 million at March 31, 2017, and decreased 35% from $6.7 million at June 30, 2016.

Fiscal Nine Month 2017 Financial Results
Revenue increased 2% to a record $55.5 million for the nine-month period ending June 30, 2017 from $54.2 million during the same period in fiscal 2016. Revenue from customers outside of the alternative carrier business increased 9% for the first nine months of fiscal 2017 compared to the same period in fiscal 2016.

Gross profit was $22.6 million, or 40.7% of revenue, for the nine-month period ending June 30, 2017, a decrease of 3% from $23.3 million, 43.0% of revenue, during the same period in fiscal 2016.

Operating expenses increased 20% to $18.8 million for the nine-month period ending June 30, 2017 from $15.7 million during the same period in fiscal 2016.

Income from operations totaled $3.8 million, or 6.8% of revenue, for the nine-month period ending June 30, 2017 compared to $7.6 million, or 14.0% of revenue, during the same period in fiscal 2016.

Net income totaled $2.6 million, or $0.19 per diluted share, for the nine-month period ending June 30, 2017, a decrease of 52% from $5.3 million, or $0.39 per diluted share, during the same period in fiscal 2016.
