Thanks, Mike, and good afternoon, everyone.
In my remarks today, I'll provide some additional details on revenue in the quarter as well as take you through the income statement and other key financial metrics. I'll then finish up with our second quarter guidance.
Q1 revenue was $1.66 billion, a decline of 6.4% core. On a reported basis, currency added 0.9 percentage points, while M&A had a negative impact of 0.1%, resulting in a reported decline of 5.6%. And overall, orders were greater than revenue in Q1 as expected. As Mike mentioned, Pharma, our largest end market declined 12%. Within pharma, biopharma declined low single digits but grew low single digits outside China, bolstered by strength in services and consumables. Small molecule was down high teens in the quarter with softness globally. The Chemical and Advanced Materials market was down 4% off a very tough comparison of 14% growth last year.
We saw broad resilience in Advanced Materials with a low single-digit increase year-on-year as well as growth sequentially. Given the extremely tough compare of high 20s growth last year, these are impressive results. As expected, the chemical side saw a decline. The Academia and Government market was up 2%. The growth in this market reflects the stability of academic funding and lab activity. Our business in the Diagnostics and Clinical market declined 5%, mid-single-digit growth in Pathology was more than offset by continued headwinds in genomics, cell analysis and LC and LC/MS. The environmental and forensics market declined 1% after growing 12% in Q1 of last year.
We continue to see new regulations around the world driving PFAS testing. Europe grew mid-single digits, while China and the Americas were down low single digits. Americas faced a difficult compare of low 30s growth last year. The Food market declined 3% but was up low single digits, excluding China. On a geographic basis, as Mike mentioned, both China and Europe exceeded our expectations while the Americas were in line with our expectations. China was down 9% and showed a sequential increase over last quarter, which was much better than expectations. China benefited from continued stabilization and a bigger-than-expected Lunar New Year impact as some customers pulled forward incremental demand from Q2.
We estimate the pull-forward impact to be roughly $15 million or 5% of China's revenue in the quarter. Even adjusting for this impact, China outperformed. Europe was down 4% year-on-year after growing 10% last year and was up mid-single digits sequentially. This was driven by continued strong demand for our ACG services, offset by muted demand in pharma and expected softness in chemicals. In the Americas, revenue was down 8% due to declines in pharma and the softness in NASD and NGS chemistries.
Moving down the P&L. First quarter gross margin was 56.0% down 50 basis points from a year ago as productivity and cost savings were offset by lower demand and mix. Our operating margin of 25.8% was down year-over-year as expected. Our ongoing cost savings initiatives are delivering as planned. Below the line, we benefited from greater-than-expected interest income in the quarter, driven by nice work from our treasury team, coupled with very strong cash flow. Our tax rate was 13.5% and we had 294 million diluted shares outstanding. Putting it all together, Q1 earnings per share were $1.29, down 6% from a year ago and ahead of our expectations.
Now let me turn to cash flow and the balance sheet. I continue to be very pleased with our cash flow generation. Operating cash flow was $485 million in the quarter, significantly above last year. In Q1, we invested $90 million in capital expenditures as we continue our planned NASD expansion. And during the quarter, we returned $69 million to shareholders through dividends. Although no shares were repurchased during the quarter, we expect to catch up on our anti-dilutive share repurchasing for the remainder of the year. In Q2, we expect a minimum of $180 million to be repurchased. All in all, we had a good start to the year. And as Mike mentioned, it reinforces our confidence in the full year guide we provided in November.
Now to our guidance for the second quarter. We expect Q2 revenue will be in the range of $1.56 billion to $1.59 billion. This represents a decline of 9.1% to 7.4% on a reported basis and a decline of 8.4% to 6.7% on a core basis against 9% growth last year. Currency and M&A combined are a headwind of 70 basis points. Our Q2 guidance also reflects the $15 million impact of the Q1 pull forward in China I mentioned earlier. Second quarter non-GAAP earnings per share expected to be between $1.17 and $1.20.
Before turning back over to Mike, I just want to express my thanks to Mike and to congratulate Padraig. Mike, it has been a real pleasure to work with you. While there have been many ups and downs in the markets these past few years, one thing I knew I could always count on is your steady leadership and strong partnership. And Padraig, congratulations again. I'm really looking forward to working with you.
And now I'll turn things back over to Mike. Mike?
