IRIDEX Announces First Quarter 2017 Financial Results

Updates Guidance for Full Year 2017

MOUNTAIN VIEW, Calif., May 3, 2017 -- IRIDEX Corporation (Nasdaq: IRIX) today reported financial results for the three months ended April 1, 2017.

Recent Financial Results and Highlights

“While our first quarter was marked by lower than expected financial results, we made significant progress towards the commercialization of the G6 platform,” said William M. Moore, President and CEO. “Our overall business was impacted by the significant expansion and transition of our sales organization over the past several months as we ramp up to meet a growing opportunity worldwide.  However, I am pleased with the progress we continue to make towards the commercialization of our G6 platform, including a growing base of thought leader support, repeat customers, broadening clinical data, and global expansion. This on-going momentum fuels our confidence in the prospects for the G6 platform to transform our business for years to come.”

First Quarter 2017 Financial Results

Revenue for the three months ended April 1, 2017 decreased 12% to $10.5 million from $11.9 million during the same period of the prior year. The decline in revenue was primarily driven by lower medical and surgical retina product revenue, and which offset the growth in G6 revenues.

Gross profit for the first quarter of 2017 was $4.5 million, or 42.6% gross margin, compared to $5.3 million, or 44.4% gross margin, in the same period of the prior year. Gross margin was primarily impacted by less efficient overhead absorption due to lower than anticipated revenues.

Operating expenses for the first quarter of 2017 were $6.3 million compared to $5.1 million in the same period of the prior year. This increase met our expectations as we have made investments to support our commercial infrastructure, particularly increased sales and marketing expenses.

Loss from operations for the first quarter of 2017 was $1.9 million, compared to income from operations of $0.2 million for the same period of the prior year.

Cash and cash equivalents were $23.9 million as of April 1, 2017.

Guidance for Full Year 2017

IRIDEX projects revenue for full year 2017 to be $46 to $49 million, down from guidance of $48 to $52 million provided on March 8, 2017.

The Company continues to anticipate sales of 400 to 450 G6 systems but currently expects G6 probe shipments to range from 35,000 to 40,000.  

IRIDEX expects revenue from its medical retina business will decline in the low single digits with some quarter-to-quarter lumpiness given the capital equipment nature of the business and that its surgical retina business will continue to decline in the mid-to-high single digits.  

Revenue growth is expected to be more heavily weighted towards the second half of 2017 as the Company begins to see the full benefits of its growth investments.
