Fiscal Q3 2015 Financial Results

Total revenue decreased 3% to $42.5 million, compared to $43.9 million in the third quarter of fiscal 2014. The decrease was primarily due to a 24% decrease in sales of the company’s Commercial & Industrial (C&I) products, which totaled $17.2 million (or 40% of total revenue) compared to $22.5 million (or 51% of total revenue) in the same year-ago period. The decrease was partially offset by a 19% increase in sales of the company’s DS products, which totaled $25.3 million (or 60% of total revenue) compared to $21.4 million (or 49% of total revenue) in the same year-ago period.

Consolidated gross profit margin as a percentage of sales (on a non-GAAP basis) was 26.9%, an improvement from 24.4% in the third quarter of fiscal 2014 (see reconciliation to GAAP, below). The increase was due to a change in the mix of products sold towards higher margin DS products as well as higher gross profit rates on sales of DS products compared to the same quarter a year ago.

Non-GAAP operating expenses totaled $10.9 million, compared to $9.6 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 loss totaled $293,000 or $(0.01) per diluted share, compared to GAAP net income of $706,000 or $0.03 per diluted share in the third quarter of fiscal 2014.

Non-GAAP net income totaled $503,000 or $0.02 per diluted share, compared to $1.1 million or $0.05 per diluted share in the same year-ago quarter (see reconciliation to GAAP, below).

Non-GAAP EBITDA totaled $1.1 million, compared to $1.6 million in the third quarter of fiscal 2014 (see reconciliation to GAAP, below).

At quarter end, the company’s cash balance totaled $16.4 million, up from $16.2 million at March 27, 2015.

Management Commentary

“We are pleased that our third quarter results were somewhat better than our expectations in terms of profits and that once again we achieved double digit growth in our digital signage product lines,” said Gerry Perkel, Planar’s president and CEO. “Our performance during the third quarter reflected our continued progress in transforming our business model enabling a more profitable and higher-growth company. In fact, revenue generated by digital signage product sales accounted for 60% of total revenue. This record mix of DS product sales drove a 250 basis point improvement in our non-GAAP gross profit margins to its highest level since we shifted our focus to digital signage in 2011.

“Our success in growing sales of our digital signage products is the result of our go-to-market strategy that includes a steady flow of innovative new products. Along those lines, our new DirectLight LED Video Wall System continues to garner industrywide acclaim and customer interest for its exquisite visual performance in mission-critical, 24/7 environments.

“We entered the final quarter of our fiscal year achieving another milestone, as we began shipping DirectLight to initial customers. We expect to continue to convert the growing interest in DirectLight into meaningful customer orders through the remainder of the year and onward. We believe there exists the potential for strong, long-term growth for indoor LED video walls, and we are well positioned to capitalize on that growth.”

Financial Outlook

“Looking ahead, fiscal 2015 remains on track to be a year of significant profit improvement, with the growth in Digital Signage revenue supporting improved profitability,” said Perkel. “We expect our expanding product portfolio and strong sales pipeline to drive further improvement in fiscal 2016.”

Given the company’s current orders and sales pipeline, management expects fiscal fourth quarter 2015 revenue to be between $49 million and $51 million, and non-GAAP net income is expected to range between $0.10 and $0.12 per diluted share. For the full fiscal year 2015, revenue is expected to be between $196 million and $198 million, which would represent an increase of 10% to 11% compared to fiscal 2014. Non-GAAP net income for fiscal 2015 is expected to range between $0.37 and $0.39 per diluted share, which would represent an increase of 37% to 44% compared to $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.
