IRIDEX Announces 2018 First Quarter Financial Results

MOUNTAIN VIEW, Calif., May 3, 2018 -- IRIDEX Corporation (Nasdaq: IRIX) today reported financial results for the first quarter ended March 31, 2018.

First Quarter Highlights

“We’re off to a solid start in 2018 and are making progress in our shift towards a glaucoma, disposables-oriented business model. Revenues in the first quarter were driven by new G6 system placements and increased probe utilization worldwide,” said William M. Moore, President and CEO. “I’m pleased with the strides our commercial team is making with both new and existing customers, as well as the impact our marketing organization is having on raising awareness on the benefits of our MicroPulse technology in treating all stages of glaucoma.  I am also pleased that we have made significant progress regarding the voluntary recall of our TrueFocus LIO Premiere™ laser accessory and have developed an action plan to return this product to the market.”

First Quarter 2018 Financial Results

Revenue for the three months ended March 31, 2018 decreased 9% to $9.5 million from $10.5 million during the same period of the prior year. The decrease in revenue was primarily due to lower retina product revenues related to the Company’s voluntary LIO recall. The decrease was partially offset by growth from G6 product revenues and the reversal of a portion of the reserves related to the LIO recall.

Gross profit for the first quarter of 2018 was $3.9 million, or 41.2% gross margin, compared to $4.5 million, or 42.6% gross margin, in the same period of the prior year. Gross margin was primarily impacted by unfavorable geographic mix and less efficient overhead absorption, partially offset by the benefit of higher margin G6 revenues and the reversal of a portion of the reserves related to the LIO recall.

Operating expenses for the first quarter of 2018 were $7.5 million compared to $6.3 million in the same period of the prior year. This increase is attributable to investments to support the Company’s commercial infrastructure, including increased sales and marketing expenses.

Loss from operations for the first quarter of 2018 was $3.6 million, compared to loss from operations of $1.9 million for the same period of the prior year.
