Fiscal Q2 2015 Financial Results

Total revenue increased 20% to $49.1 million from $41.1 million in the second quarter of fiscal 2014. The improvement was driven by a 32% increase in sales of the company’s DS products, which totaled $24.9 million (or 51% of total revenue) compared to $19.0 million (or 46% of total revenue) in the same year-ago period. Sales of C&I products increased 10% to $24.2 million (or 49% of total revenue) compared to $22.1 million (or 54% of total revenue) in the same year-ago quarter.

Consolidated gross profit margin as a percentage of sales (on a non-GAAP basis) was 25.0%, an improvement from 23.6% in the second quarter of fiscal 2014 (see reconciliation to GAAP, below). The increase was due to lower labor and overhead expenses related to improved capacity utilization, as well as a change in the mix of products sold towards higher margin DS products.

Non-GAAP operating expenses totaled $10.8 million compared to $9.4 million in the same quarter last year (see reconciliation to GAAP, below). The increase was primarily due to higher sales and marketing expenses.

GAAP net income totaled $1.6 million or $0.07 per diluted share, an increase of 607% or $0.06 per diluted share from $228,000 or $0.01 per diluted share in the second quarter of fiscal 2014.

Non-GAAP net income totaled $1.9 million or $0.08 per diluted share, an increase of 204% or $0.05 per diluted share from $612,000 or $0.03 per diluted share in the same year-ago quarter (see reconciliation to GAAP, below).

Non-GAAP EBITDA increased 90% to $2.1 million from $1.1 million in the second quarter of fiscal 2014 (see reconciliation to GAAP, below).

At quarter end, the company’s cash balance totaled $16.2 million, up 9% from $14.9 million at December 26, 2014.

Management Commentary

“Our second quarter was consistent with our expectations for strong year-over-year revenue growth, driven by sales of our industry-leading digital signage products and custom C&I displays,” said Gerry Perkel, Planar’s president and CEO. “These results also reflected meaningful progress in our transition from selling lower-margin products in mature, highly-competitive markets to delivering state-of-the-art solutions to the fast growing, multi-billion dollar market for digital signage.

“This progress was evident in the stronger performance of our DS product line, which produced a 69% increase in signage monitor sales and a 14% increase in sales of tiled LCD systems when compared to the second quarter of 2014. Q2 also marked the second straight quarter that DS product sales exceeded 50% of total revenues.

“Our positive momentum has been supported by the strategic expansion of our sales and marketing resources, which has enabled us to better capitalize on new opportunities and deepen our relationships with key resellers. During the quarter we added nearly 60 new reseller relationships and our total network of value-added resellers is over 2,000 globally.

“It was also a great quarter for new product announcements for Planar, highlighted by the introduction of our new DirectLight LED Video Wall System at the Digital Signage Expo in March. This innovative approach to video walls was well received by the industry and won the award for ‘Best New Indoor Display’ by rAVe Publications. Based upon what we see in the market, we believe there exists the potential for strong, long-term growth for indoor LED video walls.

“DirectLight complements our highly successful Clarity Matrix LCD Video Wall System, and addresses the increasing demand by customers for a seamless, high-quality video walls that meet mission-critical requirements. The unique features and functionality of DirectLight meets these demands head-on and further extends Planar’s leadership in video wall innovation. The initial customer response to this offering has been very strong, and we have been experiencing a strong level of quoting activity. We expect to begin shipping this product in fiscal Q4.”

Financial Outlook

“Our custom C&I product line has been benefitting from recurring orders from a large customer in the oil field services industry,” said Perkel. “Looking ahead, we see C&I revenue declining in the near-term as this customer delays purchasing decisions in light of low crude oil prices and correlating reduction in drilling activity. Meanwhile, some digital signage buyers are continuing to order our Clarity Matrix LCD Video Wall System and others are considering our new DirectLight System, which we will begin shipping in fiscal Q4 2015. Despite these factors, we expect fiscal 2015 to be another growth year, with increasing Digital Signage product revenues and total revenues leading to improved profitability compared to fiscal 2014. We expect this improved financial performance along with an expanding product portfolio and sales pipeline to set the stage for further improvement in fiscal 2016.”

For the fiscal third quarter ending June 26, 2015, the company expects modest year-over-year growth in DS product sales, along with a decline in custom C&I display sales, due to the factors mentioned above. Accordingly, the company anticipates revenue in the fiscal third quarter of 2015 to range between $43 million and $45 million, with non-GAAP net income at around breakeven. This compares to $43.9 million in revenue and non-GAAP net income of $0.05 per share in the third quarter of fiscal 2014.

Given the company’s current orders and sales pipeline, management expects fiscal Q4 to offer sequential improvement in revenue and profit performance compared to fiscal Q3 and fiscal 2015 revenue to be between $196 million and $202 million, which would represent an increase of 9% to 13% compared to fiscal 2014. Non-GAAP net income for fiscal 2015 is expected to range between $0.32 and $0.36 per diluted share, improving from $0.27 per diluted share in fiscal 2014.

Note Regarding the Use of non-GAAP Financial Measures

In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (GAAP), the Company’s earnings release contains non-GAAP financial measures that exclude certain items set forth in the reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures. The exclusions relate primarily to charges of a non-cash nature. Management uses the non-GAAP financial measures for internal managerial purposes, including as a means to compare period-to-period results on a consolidated basis and as a means to evaluate the Company’s results on a consolidated basis compared to those of other companies. In addition, management uses certain of these measures when publicly providing forward-looking statements on expectations regarding future consolidated basis financial results. The Company discloses this information to the public to enable investors to be able to more easily assess the Company’s performance on the same basis applied by management. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations to those financial statements should be carefully evaluated. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. The Company has provided reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures.
