Thank you, Mark. And good morning, everyone.
Coming on now to revenue less pass-through costs by quarter. As a reminder: We delivered like-for-like growth of 9.5% in Q1, 8.3% in Q2. And like-for-like growth in Q3 was 3.8%, delivering a year-to-date growth of 7.1%. The 3.8% growth was impacted by ongoing China lockdowns and obviously a COVID-related contract benefit in Q3 of 2021; and if you reverse out that benefit, would result in a 4.8% growth for the quarter. On a 3-year basis, i.e., versus 2019, as Mark has already alluded to, growth has continued to improve through the year with 9.2% in Q1, 9.7% in Q2 and 10.9% in Q3. And as Mark has already said, as a result of this momentum, we've upgraded our guidance to like-for-like growth for the full year of 6.5% to 7%.
Coming on now to growth across our business lines. The Global Integrated Agencies delivered 4.3% like-for-like growth in the quarter, made up of 4.7% for GroupM and 4% for the creative agencies. So both ahead of our overall growth for the business. PR delivered like-for-like growth of 5.8% with strong growth across all of our major businesses there, BCW, Hill+Knowlton and FGS Global.
And our Specialist Agencies declined by 3.9%, again reflecting the COVID-related contract I made mention of earlier on. And actually, excluding that impact, growth would have been 8.6% for our Specialist Agencies. And on a 3-year basis, we continue to see good growth in GroupM at 20%, PR at 19% and 17% in our Specialist Agencies.
Coming on now to our continued investments in our growth, whether that's organically through Choreograph, our data business; or in GroupM Nexus, our media planning and performance business; and most importantly, our people, investing in new talent and events like Making Space initiative, giving our people a company-wide break and a series of events across our offices to inspire and allow them to reconnect. We also continue to invest in acquisitions, 4 -- as Mark said, 4 acquisitions in the quarter: Corebiz, a Latin American e-commerce agency; the JeffreyGroup, a leading corporate communications and public affairs business in Lat Am; Newcraft, a European e-commerce consultancy based in Amsterdam; and most recently, Passport Brand Design, a leading brand design agency based in the U.S.
We also continue to invest in our transformation, our campus program, our procurement initiatives, our new systems rollout and shared services; and pleased to say we're on target to achieve annual savings of GBP 300 million for the year against 2019 baseline.
Coming on now to our major markets, where we've seen varied performance, growth in the U.K. and U.S. ahead of the overall business. And on a 3-year basis, we've seen an acceleration in performance in our U.K. business to 13.9%. Germany has been down 8.7%, again given the impact of the COVID-related contract. Excluding that, Germany would have been up 3.3%. China, down 9% on the back of down 6% in the second quarter, due to the continued impact of lockdowns. We did expect that to recover a little bit in the third quarter and the second half. We haven't yet seen that come through, and that is weighing on both our revenue and our margins as a consequence.
India is still strong, 10.7%, albeit down on Q2, reflecting the IPL benefits we saw in the second quarter. Australia is still recovering but yet to get back to 2019 levels. And Canadian growth remains strong. France still a little disappointing given client losses in 2021. And Brazil is still delivering very strong growth, double-digit growth in the quarter. And Spain is lapping some tough comparatives. So a varied performance across our major markets.
Coming on now to our net debt. There's been a year-on-year increase from GBP 1.6 billion to GBP 3.5 billion driven mainly through GBP 1 billion of share buybacks, over GBP 1 billion in share buybacks, for the last 12 months; as well as CapEx and acquisition spend to fuel our future growth and drive efficiencies in our business. We expect our year-end adjusted net debt to be around GBP 2.3 billion, reflecting the usual improvement we would see in working capital in Q4, allowing for flat trade working capital year-on-year as we've previously guided. And also of course, there's been an outflow in our non-trade working capital of GBP 300 million to GBP 400 million, reflecting the high 2021 bonus that, of course, gets paid out in 2022.
And finally, coming on now to our 2022 guidance. As I've already said, we've upgraded our revenue less pass-through cost guidance to 6.5% to 7%, to deliver an operating margin up 30 to 50 bps, reflecting our continued investment in our people, our data and technology to support this growth; with net debt expected to end the year at GBP 2.3 billion, with an average adjusted net debt-to-EBITDA ratio slightly below the 1.5x to 1.75x guidance range that we've given in the past; M&A contribution of 0.3%, consistent with what we said at our interims.
We're upgrading the FX benefit now to 7% as a result of recent exchange rate movements. As we've previously guided, we've got restructuring costs of GBP 220 million, including GBP 100 million of Workday costs anticipated in this year, 2022; and a headline tax rate of 25.5%; CapEx of GBP 350 million to GBP 400 million, again in line with our previous guidance; trade working capital flat; and GBP 300 million to GBP 400 million of outflow on non-trade I've just mentioned; and around the GBP 800 million of share buybacks which we committed to at the beginning of the year. When you add all those together, that should get you to your net debt number that we've guided to.
And with that, I'll hand you back to Mark.
