Senior Vice President & Chief Financial Officer at IDEX
Thanks, Eric. Turning to the consolidated financial results on Slide 6. Please note that all comparisons are against the prior year period, unless otherwise stated. Orders of $773 million were up 1% on a reported basis and up 2% organically. We saw mid-single-digit organic growth in FSDP and HST, which was partially offset by a mid-single-digit decline in FMT, driven by projects being pushed to the right.
Second quarter sales of $807 million was down 5% reported and 4% organically. We experienced an 11% decline in HST, while FMT and FSDP were essentially flat as compared to the prior year period. Second quarter gross margin and adjusted gross margin were 45.4%, an expansion of 70 basis points, driven by strong price cost and favorable operational productivity, partially offset by unfavorable mix, higher employee-related costs and lower volume leverage.
Second quarter adjusted EBITDA margin was 27.8%, down 60 basis points. However, as compared to Q1, adjusted EBITDA was up 180 basis points. This strong sequential expansion highlights our team's continued focus on deploying 80/20 to drive profitability as we manage through challenging market dynamics. I will discuss the drivers of second quarter adjusted EBITDA on the next slide in a moment.
On a GAAP basis, our Q2 effective tax rate was 21.2% versus 22.4% in the prior period. The decrease was primarily due to a discrete benefit from research and development incentive resolution related to prior years from an international taxing authority. Second quarter net income was $141 million, generating an EPS of $1.86. Adjusted net income was $156 million with adjusted EPS of $2.06, down $0.12.
Free cash flow for the quarter was $118 million, a decrease of 2%. We achieved a conversion rate of 75% of adjusted net income, a 310 basis point improvement on a year-over-year basis. We have a strong balance sheet and, this quarter, we repaid $25 million of the $50 million previously outstanding debt under our term facility and we paid $52.2 million in cash dividends. The dividend was 119th consecutive quarterly dividend payout.
Moving on to Slide 7, which details the adjusted EBITDA drivers. For the second quarter, adjusted EBITDA decreased by $17 million. The 4% organic sales reduction unfavorably impacted adjusted EBITDA by $23 million, flowing through at our prior year adjusted gross margin rate. The negative volume flow through was partially offset by strong price cost spread of 100 basis points in the quarter and operational productivity, resulting in a $13 million benefit over the prior year.
In the quarter, we saw unfavorable mix driven by dispensing and lower overall industrial activity. These factors resulted in a negative 48.7% organic flow through. The impact of FX lowered adjusted EBITDA by $1 million, while acquisitions, net of divestitures, was flat on a quarter-over-quarter basis as the benefits from our acquisitions were offset by adjusted EBITDA from divested companies. This resulted in a negative 42.4% flow through for the second quarter.
I will now review segment-level performance. Turning to Slide 8 and FMT segment. In Q2, orders decreased 4% organically, driven primarily by the cyclical decline in the ag market and push out an industrial project activity as Eric discussed in his opening remarks. Organic sales were flat as lower volumes, particularly in our industrial facing pump businesses, were offset by continued strong price capture.
More specifically, we are seeing stable bid rates across industrials but seeing project spending pushouts in the current macroeconomic climate. Our water businesses continue to benefit from strong municipal activity. While the ag markets are experiencing a cyclical downturn, our teams continue to make their own luck and we are pleased with our team's performance against the current backdrop. Adjusted EBITDA margin decreased 140 basis points due to higher discretionary spending, lower volume leverage and higher employee-related costs, partially offset by strong price cost spread and favorable operational productivity.
Moving on to Slide 9 and our HST segment. Despite slower-than-expected recovery in the semiconductor industry and delayed industrial projects due to demand softness, organic orders were up 5% year over year. Organic sales were down 11%, primarily driven by our life sciences and analytical instrumentation markets. While the market is experiencing a transitional period, we continue to work closely with our customers on innovation as we position ourselves for growth while we wait for the markets to recover. While we are seeing early signs of encouragement in our semicon markets, we have not yet seen the inflection in our orders.
In line with our FMT industrial businesses, our HST industrial businesses are also experiencing project pushouts. Q2 adjusted EBITDA margin for HST improved 10 basis points year over year, primarily due to the net accretive impact of acquisitions and divestitures. On an organic basis, adjusted EBITDA margin decreased 20 basis points, driven by lower volume leverage, unfavorable mix and higher employee-related costs, partially offset by operational productivity, strong price cost and lower discretionary spending. Sequentially, margins improved 150 basis points despite a sequential sales decline, which is a reflection of our strong focus on driving operational efficiency.
Now, turning to Slide 10. Organic orders in our Fire & Safety/Diversified Product segment were up 6%. Organic net sales were up 1% compared to the prior year, driven by price capture across all markets and continued dispensing project wins in emerging markets. We are seeing positive trends within the Fire & Safety business as the OEMs continue to work their backlogs down. BAND-IT saw weakness tied to auto and weaker industrial project activity. Q2 adjusted EBITDA margin declined 40 basis points year over year, primarily due to higher employee-related costs and lower volume leverage, partially offset by strong price cost and operational productivity.
With that, I would like to provide an update on our outlook for the third quarter and full year on Slide 11. Note that our guidance does not contemplate the impact from future acquisitions. For the third quarter, we project organic sales to increase 0% to 1% compared to prior year. We anticipate an adjusted EBITDA margin of approximately 27% with GAAP EPS in the range of $1.61 to $1.66 and adjusted EPS in the range of $1.85 to $1.90. On a year-over-year basis, we expect low-single-digit organic sales decline in HST and FSDP and low-single-digit growth in FMT.
Given our current view on the timing of end market recoveries, we are revising our full year outlook. We now expect revenue to decline 1% to 2% compared to a prior outlook of growth of 0% to 2%. Given the revised organic assumptions, we expect full year adjusted EBITDA margin of approximately 27% versus a prior outlook of approximately 28%. We project GAAP diluted EPS to range from $6.85 to $6.95 compared to our previous guidance of $7.13 to $7.43 and adjusted EPS to range from $7.80 to $7.90 versus a previous outlook of $8.15 to $8.45. The update to our full year revenue guidance implies mid-single-digit organic sales decline in HST with low-single-digit growth in FMT and FSDP. We will continue to closely monitor the end markets while maintaining our focused effort on driving profitable growth.
With that, I will turn it over to Eric for closing remarks.
