Scott B. Ullem
Corporate Vice President, Chief Financial Officer at Edwards Lifesciences
Great. Hey, thanks a lot Bernard. We are pleased with our sales performance in the first half of the year. Posting our second consecutive quarter of double-digit constant currency growth. All product groups grew double-digits and sales were balanced across regions, with the exception of Japan, which was impacted by the trialing of competitive TAVR products.
We achieved total sales in the quarter of $1.53 billion, which represents 12% year-over-year, constant currency growth. We achieved adjusted earnings per share of $0.66. Contribution from our better-than-expected sales performance was partially offset by higher-performance based compensation and investments in our transcatheter operations in support of our growth strategy. Our GAAP earnings per share of $0.50 was impacted by the intellectual property agreement, I commented on last quarter.
We previously had a long-term intellectual property agreement with Medtronic that expired last year. And in consideration for the new agreement, we paid $300 million, approximately half of which has been expensed and the other half will be amortized over the next 15 years. A reconciliation between our GAAP and adjusted earnings per share for these and other items is included with today's release.
I'll now cover some additional details of our second quarter sales results and full-year 2023 outlook by product group. The continuation of double-digit global TAVR growth reflected a more stable hospital staffing environment as well as strong adoption of the SAPIEN family of valves. US TAVR sales growth was driven by the launch of SAPIEN 3 Ultra RESILIA, which remains on-track to represent the majority of our US TAVR sales before year end. In Europe, Edwards sales growth was driven by the continued demand of our SAPIEN platform and was broad-based by country. We still see some health system capacity challenges, but are encouraged that centers are adapting to continue to treat their patients. In Japan, although growth was below our expectations in Q2, we anticipate the growth rates will improve, driven by the ongoing launch of SAPIEN 3 Ultra RESILIA. For global TAVR sales, we are adjusting the low-end of our outlook slightly higher to $3.85 billion to $4.0 billion. We now expect full-year TAVR growth to be 10% to 13% on a constant-currency basis versus previous guidance of 10% to 12%.
TMTT growth in the second quarter was driven by strong procedure volumes, adoption of our differentiated PASCAL Precision platform and activation of more centers across the US and Europe. Overall, we're pleased with our continued progress toward bringing a portfolio of TMTT therapies combined with contemporary clinical data in order to achieve our vision of transforming lives of patients with mitral and tricuspid valve disease. We now expect full-year 2023 sales of $180 million to $200 million versus our previous expectation of $170 million to $200 million.
In Surgical Structural Heart, 13% constant currency sales growth in the quarter was driven by the adoption of Edwards' premium products as well as strength in valve surgery procedures as hospital staffing levels have continued to improve. Based on positive year-to-date performance, we now expect that our full-year sales will be in the range of $960 million to $1.02 billion versus previous guidance of $870 million to $970 million, this revised range implies low double-digit constant currency growth in 2023.
Finally, turning to Critical Care, we continue to expect full-year 2023 sales of $870 million to $940 million.
For total Edwards, based on the strong first half of the year, we now forecast full-year 2023 sales to be in the range of $5.9 billion to $6.1 billion versus prior guidance of the high-end of $5.6 billion to $6.0 billion. We now expect full-year total company sales growth to be in the 10% to 13% range on a constant currency basis versus previous guidance of 10% to 12%. Lastly, we now expect our full-year adjusted earnings per share to be between $2.50 and $2.60. We are projecting third quarter sales to be between $1.44 billion and $1.52 billion. We are also projecting third quarter adjusted EPS of $0.55 to $0.61.
I'll now cover additional details of our P&L. For the second quarter, our adjusted gross profit margin was 77.7%, as expected, compared to 80.5% in the same-period last year. This reduction was driven by a less favorable impact from foreign exchange. We continue to expect our full-year 2023 adjusted gross profit margin to be between 76% and 78%. Selling, general and administrative expenses in the quarter were $469 million or 30.6% of sales compared to $409 million in the prior year. This increase was driven by performance-based compensation and investments in transcatheter field-based personnel in support of our growth strategy. We continue to expect full-year 2023 SG&A as a percent of sales to be 29% to 30% as we invest in-field based personnel and our therapy adoption initiatives.
Research and development expenses in the second quarter grew 8% over the prior year to $270 million or 17.7% of sales. This increase was primarily the result of continued investments in our transcatheter aortic valve innovations, including increased clinical trial activity. For the full-year 2023, we continue to expect R&D to be 17% to 18% of sales as we invest in developing new technologies and generating evidence to support TAVR and TMTT.
During the second quarter, we recorded a $27 million reduction in the fair value of our contingent consideration liabilities, which benefited earnings per share by $0.04. This benefit was excluded from our adjusted earnings per share of $0.66, this reflects an adjustment of assumptions regarding potential milestone payments for a previous acquisition.
Turning to taxes, our reported tax rate this quarter was 9.7% or 13.1% excluding the impact of special items. Our rate benefited from higher R&D tax credits and a 200 basis point excess tax benefit from stock based compensation. We continue to expect our full-year tax rate, excluding special items, to be 13% to 17%. Foreign exchange rates decreased second quarter reported sales growth by 70 basis points or $8 million compared to 2022. At current rates, we continue to expect an approximately flat year-over-year impact to full-year 2023 sales compared to 2002. Foreign exchange rates negatively impacted our second quarter gross profit margin by 220 basis points compared to the prior year. Relative to our April guidance, FX rates had a minimal impact on second quarter earnings per share,
Adjusted free cash flow for the second quarter was $286 million, defined as cash flow from operating activities of $34 million, less capital spending of $48 million, and excluding a $300 million payment related to the Medtronic intellectual property agreement I mentioned earlier. We continue to expect full-year 2023 adjusted free cash flow will be between $1.0 billion and $1.4 billion.
Before turning the call back over to Bernard, I'll finish with an update on our balance sheet and share repurchase activities. We continue to maintain a solid and flexible balance sheet with approximately $1.5 billion in cash, cash equivalents and short-term investments as of June 30th. We continue to expect average diluted shares outstanding for 2023 to be between 610 million and 615 million. We have approximately $650 million remaining under our current share repurchase authorization.
And with that, I'll hand it back over to you, Bernard.
