Thank you, Art. Good morning to everyone on the line, and thank you for joining the call. While ANI's third quarter 2019 key financial metrics fell short of both internal and external expectations, our financial position and financial performance remain very strong. In fact, this is the 15th consecutive quarter that ANI has posted year-over-year top line sales growth.
As we will discuss, we have a diversified portfolio, a strong balance sheet position, an extremely solid track record of business development and remain on track to file the most promising drug in the company's history with the FDA. With this morning's announcement, we are resetting our guidance for 2019.
During the third quarter, we experienced competitive actions against our EEMT franchise and our EES franchise faces competition from 2 newly approved market entrants in the fourth quarter. These market realities have led us to recalibrate near-term expectations. As such, we are guiding to full year revenues of between $209 million to $212 million, reflecting fourth quarter revenues of between $50.4 million and $53.4 million. Full year non-GAAP adjusted EBITDA of between $84.7 million and $86.8 million, reflecting fourth quarter projections of $18.9 million to $21 million and full year non-GAAP adjusted earnings per diluted share of between $5.06 and $5.23.
These reductions occurred during a period in which we are building momentum behind our late September 2019 launch of Vancomycin Oral Solution. This product provides an FDA-approved alternative to a market that is largely served by compounding pharmacies. It is not a typical AB-rated generic launch. And therefore, we currently anticipate revenues to ramp over time as we build market awareness and product adoption.
In addition, we look forward to our upcoming December launch of Bretylium Tosylate Injection, our first marketed injectable product for use in emergency room settings. We currently anticipate that these products and other planned generic product launches will be meaningful growth drivers in 2020 and are examples of our increasingly diverse commercial product offerings.
In addition, we have a healthy balance sheet and strong cash flow that we intend to continue to leverage and support business development activities. During the third quarter of 2019, we generated $21.8 million of cash flow from operations, resulting in unrestricted cash and cash equivalents of $59.7 million as of September 30, 2019. This balance is reflective of $40.8 million of year-to-date cash flow from operations and is net of $21.2 million of cash utilized for business development activities and nearly $5 million of capital expenditures made during the first 9 months of the year. Total net debt as of the balance sheet date was reduced to $130 million, representing 1.5x net leverage on both a trailing 12-month basis and when utilizing the midpoint of our revised full year 2019 guidance.
As previously discussed, we remain on track to refinance the upcoming December 1 maturity of our $118.75 million convertible debt in the form of fully committed financing included in our $265 million senior secured credit facility. In addition, the $75 million revolver portion of this facility remains undrawn and coupled with our existing cash and cash flow from operations provides us with significant flexibility in continuing to pursue further business development transactions.
Turning to key P&L metrics. For the quarter ended September 30, ANI posted net revenue of $51.3 million, adjusted non-GAAP EBITDA of $19.8 million and adjusted non-GAAP EPS of $1.23 per diluted share. At $51.3 million, net revenue for the third quarter of 2019 was up $0.6 million or 1% versus prior year as gains in our generic and brand pharmaceutical product categories were tempered by declines in contract manufacturing and royalties.
Net revenue gains were driven by the late September launch of Vancomycin Oral Solution, higher sales volumes of both our brand Vancocin and generic Vancomycin tablets and higher sales volumes of Atacand and candesartan. These gains were tempered by decreased sales of the Arimidex, EEMT and Diphenoxylate-Atropine.
Cost of sales in the current year period was $15 million or 29% of net revenues as compared to $15.6 million or 31% of net revenues in the prior year period. The approximate 2-point year-over-year improvement in margin is principally due to lower royalty expense resulting from a royalty buyout completed in the first quarter of 2019.
Selling, general and administrative expenses were $14.4 million as compared to $11.8 million in the prior year, driven by a full quarter worth of cost related to ANI Canada, which was purchased in August of 2018, increased U.S.-based headcount and pharmacovigilance costs and continued support of the expansion of our portfolio, higher GDUFA and PDUFA user fees, higher legal fees and increased sales and marketing-related costs.
Research and development costs totaled $5 million in the quarter as compared to $4.7 million in the year ago period. Organic R&D spend continues to be driven by investment behind Cortrophin and work related to our underlying generic pipeline. Third quarter expense includes a $328,000 charge related to a milestone paid to a third-party development partner upon the FDA approval of the product in development. Typically, a payment of this nature would be capitalized to intangible assets. However, with current commercial forecast for this particular drug did not support capitalization, and therefore, we expensed the P&L as incurred. This item has been added back to our adjusted non-GAAP metrics for the quarter.
As Art mentioned, we continue to successfully complete key steps on our path to a March 2020 sNDA filing for Cortrophin. As part of our activities to date, the company has purchased and expended raw materials, active pharmaceutical ingredients and finished dose product in its R&D efforts. All of these costs -- excuse me, all cost related to this activity has been expensed as incurred to the P&L. However, starting in the third quarter, we began to purchase inventories that we currently expect will be utilized in salable commercial batches upon FDA approval of our prior approval supplement filing for this product. Ordinarily, materials purchased for commercial sale would be capitalized as inventory. However, since we are dealing with a novel product that must clear the supplemental NDA regulatory pathway with the FDA, GAAP dictates that such costs cannot be capitalized and must be expensed when purchased. In order to shed transparency on the physical build of Cortrophin inventory, starting with the third quarter, we have broken this activity out on a separate line item on the P&L and have disclosed further information in the footnote #14 to the financial statements.
Total expense for the third quarter was $195,000, which has been added back to our non-GAAP metrics. Most importantly, however, from an operational perspective, we are planning for success, and we anticipate our purchase of commercial levels of raw materials and API will significantly increase in the fourth quarter of 2019 and during the course of 2020.
On a GAAP basis, fully diluted earnings per share of $0.32 decreased $0.10 from the year ago period. Similar to the second quarter of this year, the calculation of our GAAP EPS includes the dilutive effect of our convertible debt, as GAAP requires that our diluted weighted average shares outstanding include the theoretical dilution that would occur at share prices above the $69.48 conversion price on the face of the convertible debt. The inclusion of these theoretical shares negatively impacted GAAP EPS by less than $0.01 in the quarter. Our adjusted non-GAAP diluted earnings per share excludes these and other impacts and was $1.23 per diluted share, down $0.06 or 5% from prior year.
As discussed on the second quarter call, from an economic perspective, our shareholders are protected from equity dilution up to a share price of $96.21 due to the hedging program that the company put in place in 2014. And as such, we currently anticipate no equity dilution associated with the December 1 maturity of our convertible notes. On a year-to-date basis, we have generated $158.6 million of net revenues, $65.8 million of adjusted non-GAAP EBITDA and $3.98 of adjusted non-GAAP diluted earnings per share, representing year-over-year gains of 10%, 6% and 6%, respectively.
In summary, while we acknowledge the revision to near term expectations, we remain steadfast in our confidence to weather normal course competitive pressures and to continue to leverage our portfolio, our balance sheet and the talent of our 300-plus colleagues to continue the long-term growth and success of ANI. I will now turn the call back to our President and CEO, Art Przybyl.
