Thank you. And good afternoon, everyone. Brian and I would like to thank you for taking the time to participate in our third quarter 2018 earnings call today.
Before we begin, I need to read the following safe harbor statement. Statements or comments made on this conference call may be forward-looking statements that include financial projections or other statements of the company's plans, objectives, expectations or intentions. These matters involve certain risks and uncertainties. Our actual results may differ significantly from those projected or suggested in any forward-looking statement due to a variety of factors, which are discussed in detail in our recent SEC filing.
Further, we will discuss both GAAP and non-GAAP financial information on this call. We believe that presentation of non-GAAP information provides you with useful supplementary data concerning the company's ongoing operations and is an appropriate way for you to evaluate the company's performance. Non-GAAP results are, however, provided for informational purposes only. Please refer to the press release and related tables for GAAP information and a reconciliation of GAAP to non-GAAP information. We also posted to our website, in our Investor Relations tab, a description as well as a reconciliation of GAAP measures to which we will refer on this call. With that complete, I'll begin by going over our results for the quarter; and then turn it over to Brian, who will provide an operational review and outlook, followed by a Q&A session.
The third quarter was another productive and progressive quarter for Issuer Direct, as we finalized the acquisition of FSCwire in July; completed a secondary public offering in August; and continued to make enhancements to Platform id., resulting in the release of our conference management module last week.
Focusing on the results for the quarter. Total revenue increased 11% or $324,000 to $3,255,000 for the third quarter of 2018, as compared to $2,931,000 for the same period of the prior year. Revenue for the 9 months ended September 30, 2018, increased 15% or $1,355,000 to $10,584,000, as compared to $9,229,000 for the same period of the prior year.
Revenue from customers obtained from our acquisitions of Interwest Transfer Company and FSCwire totaled $526,000 and $1,325,000 for the 3 and 9 months ended September 30, 2018, of which $46,000 and $142,000 came from additional subscriptions to Platform id. with services cross-sold to these customers.
Platform and Technology revenue increased $309,000 or 17% to $2,085,000 for the third quarter of 2018 and increased $1,077,000 or 20% to $6,363,000 for the 9 months ended September 30, 2018. Platform and Technology revenue increased to 64% of our total revenue for the third quarter of 2018 compared to 61% for the third quarter of 2017. The increase in revenue for the quarter is primarily the result of additional licenses of Platform id., as we added an additional 33 subscriptions of Platform id. with an annual contract value of $343,000, bringing our total to 89 net new subscriptions for the year with an annual contract value of $907,000. We also achieved growth in ACCESSWIRE revenue primarily due to the addition of customers acquired in the FSCwire acquisition as well as revenue from our transfer agent module due to the addition of customers acquired in the Interwest acquisition. These increases were offset by the continued decline in revenue of our shareholder outreach offering that are specifically tied to our annual report distribution services.
Services revenue of $1,170,000 for the third quarter of 2018 increased 1% or $15,000 compared to the third quarter of 2017 and increased $278,000 or 7% to $4,221,000 for the 9 months ended September 30, 2018, compared to the same period of the prior year. The increases are primarily the result of an increase in transfer agent services due in combination to the addition of Interwest customers as well as an increase in activity of our longer-term Issuer Direct transfer agent customers. The increase in transfer agent revenue was partially offset by the continued decline of revenue from our legacy Annual Report Service as well as decline in revenue from our compliance services as we continued to face pricing pressure in the market from customers beginning to take advantage of our platform offering.
It is important to note, when comparing results to previously filed reports, $157,000 and $550,000 of revenue during the 3 and 9 months ended September 30, 2017, respectively, which were previously reported as Services revenue, were reclassified to Platform and Technology revenue. This was the result of the adoption of a new accounting pronouncement as of January 1, 2018, that required us to separate the revenue in bundled contracts for our ARS or shareholder outreach offering, which included both electronic and physical hard copy delivery of our customers' annual reports. The reclassified amounts represent the allocation of contract value of electronic delivery of the annual reports. All results have been appropriately adjusted for comparison purposes.
Switching to gross margin. Our overall gross margin percentage was 70% and 71% for the 3 and 9 months ended September 30, 2018, respectively, compared to 72% and 73% for the same period of the prior year. It is noted that there was an increase in cost of revenues of $117,000 and $373,000 for the 3 and 9 months ended September 30, 2018, respectively, due to an increase in amortization of capitalized software placed in service in 2017.
Platform and Technology gross margin percentage was 77% and 79% for the 3 and 9 months ended September 30, 2018, respectively, compared to 83% and 84% for the same periods in 2017. Again, there was an increase in cost of revenues due to the increase in amortization I noted earlier as well as additional costs as we continued to expand our news distribution capabilities. Gross margin percentage for our Services revenue stream was 57% and 60% for the 3 and 9 months ended September 30, 2018, respectively, compared to 55% and 58% for the same periods of the prior year.
Moving down the income statement. Operating expenses increased $526,000 or 32% and $1,358,000 or 26% during the 3 and 9 months ended September 30, 2018 as we continued to invest in our business for top line growth. Majority of the increase is in product development, which has more than doubled over the prior year due to less capitalization and continued development of new products associated with Platform id. as well as modules placed into production during 2017. In a few minutes, Brian will talk further about our new conference management module and soon-to-come insight and analytics platform.
General and administrative expenses increased 24% for the quarter and 15% year-to-date as a result of an increase in stock compensation as well as additional G&A expenses associated with both Interwest and FSCwire, some of which we hope to streamline as the integration has now been completed. Sales and marketing expenses increased 18% for both the quarter and year-to-date due to an increase in our sales and marketing teams and costs associated with expanding our distribution capabilities. Lastly, amortization expense increased due to additional amortization resulting from intangible assets acquired as part of both the Interwest and FSCwire acquisitions.
For tax purposes, we recognized income tax expense of $32,000 and $246,000 for the 3 and 9 months ended September 30, 2018, as compared to $174,000 and $438,000 during the same periods of the prior year. Lower tax expense is the result of lower pretax income as well as a decrease in the statutory rate in 2018, offset by a benefit in 2017 related to the exercise of stock compensation.
For GAAP purposes, we recorded net income of $86,000 or $0.02 per diluted share for the third quarter of 2018, as compared to net income of $308,000 or $0.10 per diluted share for the same period of 2017. For the 9-month period ended September 30, 2018, we recorded net income of $772,000 or $0.23 per diluted share compared to net income of $1,126,000 or $0.37 per diluted share for the first 9 months of 2017. The decrease in earnings per share was due in part to the additional shares outstanding as a result of the secondary offering that closed during the third quarter of 2018.
Looking at some non-GAAP metrics. Total EBITDA for the third quarter of 2018 was $473,000 or 15% of revenue compared to $663,000 or 23% of revenue during the same period of the prior year. On a year-to-date basis, EBITDA was $2,063,000 or 19% of revenue compared to $2,093,000 or 23% of revenues for the first 9 months of 2017.
Non-GAAP net income was $411,000 or $0.11 per diluted share for the third quarter of 2018 compared to $445,000 or $0.15 per diluted share for the third quarter of 2017 and $1,531,000 or $0.47 per diluted share for the 9 months ended September 30, 2018, compared to $1,441,000 or $0.48 per diluted share for the same period during the prior quarter, again a decrease in non-GAAP earnings per share despite similar or in the case of the 9 months ended September 30, 2018, an increase in non-GAAP net income was due in part to the additional shares outstanding as a result of our secondary offering that closed during the third quarter of 2018.
Changing to the cash flow statement. We continued to generate positive cash flow from operations as we generated an additional $564,000 during the third quarter of 2018 compared to $638,000 during the same period of the prior year, bringing total cash flow from operations to $2,153,000 for 2018 compared to $2,095,000 during the same period of the prior year. Also, due to our focus on selling subscriptions of Platform id., we've increased deferred revenue by 57% since year-end, bringing the total to $1,389,000.
As you may have seen in a recent press release, our Board of Directors have decided to discontinue the quarterly dividend in order to direct the funds on our balance sheet toward reinvestment in our business, specifically Platform id.; our sales and marketing team; as well as acquiring complementary businesses, products, technologies and/or assets, which we are committed to focus on it in the upcoming quarters.
With that, I will turn it over to Brian, who will now talk further about our new products and outlook for the remainder of 2018 and beyond.
