·

The net loss in the first quarter of 2015 included acquisition-related charges of $0.8 million, amortization of intangible assets of $0.4 million and stock compensation of $0.2 million, compared to stock compensation of $0.2 million in the first quarter of 2014;

·

Adjusted EBITDA was a loss of $0.1 million, in part due to one-time costs associated with kicking off international sales of SharpSpring and higher commissions on new SharpSpring sales during the period; and

Recent Operational Highlights

·

Added over $1 million in new annual recurring revenue to the SharpSpring platform during Q1, showing 45% growth from last quarter and 120% growth in bookings compared to Q3;

·

Announced we are on track to achieve or exceed the target of having $5 million of revenue under contract for SharpSpring by the end of 2015, which would be five times the level of revenue under contract at the time SharpSpring was acquired in August 2014;

·

Successfully integrated SMTP’s email delivery capabilities into the GraphicMail and SharpSpring sending platforms, allowing customers to benefit from improved deliverability of emails; and

·

Announced SharpSpring had achieved a major milestone in January 2015 by surpassing 1,000 companies using its advanced marketing automation platform.

“We had a strong start to the year and saw our acquisition strategy gain real traction in the market on a domestic and international scale. During the first quarter, we had tremendous success selling our SharpSpring solution to both marketing agencies and end customers, with over $1 million of new annual recurring revenues added this quarter alone,” said Jonathan Strimling, CEO of SMTP. “We are now reaching larger, higher-value customers and our international sales channel is just beginning to ramp up. We also expect revenues per customer to grow over time for both new and existing customers. Although Q1 is a seasonally weaker quarter for the GraphicMail product and our relay businesses, and we experienced some currency headwinds in Q1 related to our international operations, we are pleased with the results of the quarter and look forward to capitalizing on the significant growth opportunities in front of us.”
