MINNEAPOLIS, July 22, 2021 (GLOBE NEWSWIRE) -- Clearfield, Inc. (NASDAQ: CLFD), the specialist in fiber management for communication service providers, reported results for the fiscal third quarter and nine months ended June 30, 2021.

Management Commentary
“Fiber-fed broadband is being recognized as the answer for future-proofed connectivity to the American home and business,” said Clearfield President and CEO Cheri Beranek. “Our record-setting financial performance for the third quarter and first nine months of fiscal 2021 reflects Clearfield’s unique positioning in the market and our ability to capitalize on the robust growth vectors. The continued demand for high-speed broadband drove a 49% year-over-year increase in net sales to a record $38.7 million, bringing our total net sales for the first nine months of the year to a record $95.5 million, which was up 45% year-over-year.

“The labor-saving practices that are instrumental to Clearfield’s product architecture are being recognized by service providers throughout the broadband marketplace. Order bookings, which accelerated at the end of the second quarter, continued their momentum in the third quarter, resulting in a 377% year-over-year increase in backlog to $40.3 million. We continue to build additional capacity to respond to the demand and expect to ship the majority of our backlog in our current quarter ending September 30, 2021. In addition, due to the unprecedented lead times and challenges in the global supply chain, we are working with our customers to place longer lead-time purchase orders to ensure availability of components and materials from our supply chain. Based on current supply chain dynamics, lead times have stretched to 8 to 10 weeks for certain product categories. Over the next several quarters, we will be working to normalize lead times to more historic levels of 4 to 6 weeks from receipt of purchase order.

“Our customers, no matter if they are local exchange carriers, over-builders, cable providers, rural electrical utilities or new to this market, recognize that fiber is the only technology to provide symmetrical up-stream and down-stream performance. Currently, there are multiple government funded programs that are accelerating broadband deployment, such as the Rural Digital Opportunity Fund (RDOF), which will start to be deployed later this summer and fall. In addition, the proposed bi-partisan infrastructure framework looks promising toward enhancing the funding available to future-proof broadband deployment.

“Looking ahead, we believe all our broadband markets remain ripe for sustained growth. The market presence we have established over the last 10 years, along with our recent strategic investments, will enable us to respond to market demand and grow with our customers. While the supply chain remains volatile and may pose challenges in the future, our strong financial performance and $40.3 million backlog, give us confidence to increase our net sales guidance for fiscal 2021 to $130 million to $135 million, which represents year-over-year growth of more than 40%. We anticipate our selling, general and administrative costs will also grow moderately, as increased travel resumes, and we add additional customer-facing positions. We anticipate net income as a percentage of total net sales to be consistent with year-to-date levels.

“Over the last three years, we have been building upon a strategic plan that began as our ‘Coming of Age’ plan and then became our ‘Comes of Age’ plan this past year. Moving forward, we are now underway with our ‘Now of Age’ plan in which we offer the maturity and capacity to scale to this expanding marketplace. The multi-year plan is designed to capture the fiber to the home and business market share Clearfield was built to obtain, while delivering the innovation for new and existing markets in the years ahead. While very early, we believe with current demand, new government initiatives and overall market strength our, current market forecasts will translate to projected annual net sales of $150 million to $160 million in fiscal year 2022, representing growth of 15% to 20% over projected fiscal year 2021 revenues.”

Third Quarter of Fiscal 2021 Financial Results
Net sales for the third quarter of fiscal 2021 increased 49% to $38.7 million from $26.0 million in the same year-ago quarter. The increase in net sales was primarily due to higher sales in the Company’s Community Broadband, International and Multiple System Operators (MSO or Cable TV) markets, partially offset by decreases in the Company’s Legacy and National Carrier markets.

Gross profit for the third quarter of fiscal 2021 increased 59% to $17.1 million (or 44.2% of net sales), from $10.8 million (or 41.5% of net sales) in the same year-ago quarter. The increase in gross profit margin was due to a favorable product mix associated with higher net sales in the Company’s Community Broadband markets and cost reduction efforts across the Company’s product lines, including increased production at its Mexico plants as well as manufacturing efficiencies realized with increased sales volumes.

Operating expenses for the third quarter of fiscal 2021 totaled $9.4 million (or 24.4% of net sales), which compares to $7.2 million (or 27.8% of net sales) in the same year-ago quarter. The increase in operating expenses consisted primarily of higher compensation costs related to performance compensation accruals.

Income from operations for the third quarter of fiscal 2021 increased 115% to $7.7 million from $3.6 million in the same year-ago quarter.

Income tax expense for the third quarter of fiscal 2021 increased 126% to $1.7 million, or an effective tax rate of 22.1%, from $763,000, or an effective tax rate of 20.3%, in the same year-ago quarter due to higher taxable income.

Net income for the third quarter of fiscal 2021 totaled $6.1 million, or $0.44 per diluted share, a 104% improvement from $3.0 million, or $0.22 per diluted share, in the same year-ago quarter.

Net sales increased 45% to $95.5 million for the nine months ended June 30, 2021 from $65.8 million during the same period in fiscal 2020.

The increase in gross profit dollars was due to increased sales volume. The increase in gross profit margin was due to cost reduction efforts across the Company’s product lines, including greater use of its Mexico manufacturing facilities as well as manufacturing efficiencies realized with increased sales volumes.

Operating expenses increased 16% to $25.6 million (or 26.8% of net sales) for the nine months ended June 30, 2021, from $22.0 million (or 33.4% of net sales) during the same period in fiscal 2020.
