Management Commentary:

“We are encouraged with our performance in the first quarter of 2018 and believe that it provides a solid base for the remainder of the year,” said Vincent D. Kelly, chief executive officer. “First quarter results were in line with our seasonal expectations, and we saw strong year-over-year performance in a number of key operating measures, including revenue levels and average deal size, as well as wireless subscriber retention. We accomplished this as we increased our investment in our business by enhancing and upgrading our product development team and tools as well as our sales infrastructure and management. We believe this effort will yield significant future benefits in the form of our improved, integrated communication platform, Spok Care Connect®, as well as higher future bookings levels, and ultimately margins, supported by our enhanced and upgraded sales team. Overall, we continued to operate profitably, enhance our product offerings, and operate as a debt-free company. We also executed against our capital allocation strategy.” Kelly added, “Throughout 2018, we will remain focused on returning value to our shareholders through our capital allocation strategy, which includes dividends, share repurchases and key strategic investments in our products and business to create sustainable growth.”

Business Outlook:

For the full-year 2018, adjusted to exclude the adoption of ASC 606, the Company continues to expect total revenue to range from $161 million to $177 million, operating expenses (excluding depreciation, amortization

and accretion) to range from $158 million to $165 million, and capital expenditures to range from $4 million to $8 million.

(a) Slight variations in totals are due to rounding.
(b) EBITDA or earnings before interest, taxes, depreciation, amortization and accretion is a non-GAAP measure and is presented for analytical purposes only.
(c) EBITDA is the starting point for calculation of operating cash flow for purposes of the Company’s short term and long term incentive plans. Management and the Board of Directors also rely on EBITDA for purposes of determining the Company’s capital allocation policies. We define OCF as EBITDA less purchases of tangible assets and severance expense in determining whether management has achieved certain performance objectives for the year as set by our Board of Directors in awarding annual and long term incentive compensation to senior executives.
(d) Adjusted EBITDA represents EBITDA adjusted to exclude the adoption of ASC 606. Adjusted EBITDA is used by the Company for purposes of comparison to prior period results during its year of transition (2018) under the modified retrospective approach.
