Kevin Berryman
President and Chief Financial Officer at Jacobs Solutions
Thank you, Bob and turning to slide nine for a financial overview of our fourth quarter results. Fourth quarter gross revenue grew 8% year-over-year and net revenue 6% and up 11% year-over-year on a constant-currency basis. All lines of businesses grew fourth quarter revenues over 9% versus year-ago in constant currency. Adjusted gross margin in the quarter as a percentage of net revenue was 26% and improved slightly from the third quarter, but was approximately down 130 basis-points year-over-year, primarily driven by one, our CMS line of business due to the newly ramped remediation contract and two, investments in incremental employees in PA in advance of large wins such as the UK MOD award that will ramp over the coming months.
We expect gross margins to modestly improve from Q4 levels during fiscal 2023 driven by recent wins in cyber, favorable revenue mix, the recent wins in PA Consulting and continued strong performance in our People & Places Solutions business. Adjusted G&A as a percentage of net revenue was 15.2%, down 40 basis points from Q3 and down 200 basis points year-over-year. During the quarter, we benefited from lower labor expenses as we managed our cost structure. We are targeting G&A as a percentage of net revenue to stay below 16% for the full fiscal year 2023.
GAAP operating profit was $309 million and was mainly impacted by $52 million of amortization from acquired intangibles and other acquisition deal related costs from restructuring efforts of $14 million with over half associated with integration cost of acquisitions and finally a positive benefit from third party recoveries of $27 million pre-tax which we excluded from our adjusted results.
Adjusted operating profit was therefore $347 million, up 15% year-over-year and on a constant-currency basis it was up 19% year-over-year. Our adjusted operating profit to net revenue was 10.7%, up 80 basis points year-over-year. I'll discuss the moving parts later when reviewing the line of business performance. GAAP EPS from continuing operations was $1.75 per share and included a $0.16 benefit from the third party recovery receivable, a $0.12 benefit to align to our effective adjusted tax rate, offset by a $0.27 impact related to the amortization charge of acquired intangibles and since $0.06 from transaction restructuring and other related cost.
Excluding these items, third quarter adjusted EPS was $1.80, up 14% year-over-year and up 18% in constant-currency. Jacobs consolidated Q4 adjusted EBITDA was $350 million and was up 13% year-over-year, representing 10.8% of net revenue. On a constant currency basis, adjusted EBITDA was up 17% year-over-year. Finally backlog was up 5% year-over-year and 8% on a constant-currency basis. Sequentially backlog was impacted by the strengthening US dollar at year end compared to the end of the third quarter. As an example, the dollar strengthened 8% versus the pound sterling from the end of Q3 to the end of Q4. As a result, on a constant currency basis backlog was flat sequentially. The revenue book-to-bill ratio was 0.94 times with our gross margin book-to-bill of 1.05 times, given the higher-margin profile within backlog on both a year-over-year and sequential basis.
Our book-to-bill ratios continue to be impacted by the burn of the approaching Kennedy NASA rebid, as backlog continues to fall until which time the rebid is awarded.
Now moving to Slide 10 for a brief recap of our full year 2022 performance. [Technical Issues] gross revenue grew 6% year-over-year and net revenue grew 10% in constant currency. On a reported basis, we expect fiscal 2023 revenue growth in the mid single-digits and high-single digits on a constant-currency basis. GAAP operating profit was $918 million, up significantly year-over-year driven by a material decrease in one-time items related to transaction and restructuring, as well as solid underlying constant currency growth in the business.
GAAP EPS was $4.98 and adjusted EPS was $6.93 up 10% year-over-year and up 13% on a constant-currency basis. Adjusted operating profit grew 10.6% and was up 13% on a constant currency basis. Operating profit margins expanded nearly 30 basis points to 10.4%, driven by revenue mix benefits and lower support cost.
Adjusted EBITDA was $1.36 billion, up 10% and up 12% in constant currency. As a percentage of net revenue, adjusted EBITDA was 10.8% up 20 basis points from fiscal 2021. We expect modest adjusted operating profit margin expansion in fiscal 2023 driven by a combination of a higher margin revenue mix and lower employee related costs. However, adjusted EBITDA margins are expected to be flat year-over-year as other income will be burdened primarily by unfavorable pension costs driven by the higher interest rate environment.
On a trailing 12 month basis, book-to-bill was 0.97 times and gross margin book-to-bill was over 1 at 1.05. Regarding our LOB [Phonetic] performance, let's turn to Slide 11 for Q4 performance and Slide 12 for full-year performance. Starting with CMS, Q4 revenue was up 10% year-over-year and up 12% in constant-currency. BlackLynx contributed approximately $22 million to the fourth quarter revenue. Fiscal 2020 revenue on a reported and constant currency basis grew 3% as the part of the year as the first part of the year did not benefit from the ramp of the Idaho nuclear remediation win.
BlackLynx contributed $50 million in revenue for fiscal year 2022. For fiscal year 2023, we expect revenue growth in the mid single-digit for the CMS business and higher double digit growth in our Divergent Solutions unit. Q4 CMS operating profit was $95 million, down 17% year-over-year and down 14% on a constant-currency basis. Operating profit margins as a result were down 2020 basis-points year-over-year to 6.9%.
Consistent with our previous outlook, Q4 operating profit and operating margin percentage were impacted by a rate true-up in our cyber and intelligence business. The rate true-up was related to higher G&A costs over the course of the year, given the slow ramp-in the business during the continuing resolution.
Looking-forward, we have successfully been awarded a large new classified cyber one that was previously delayed during the continuing resolution, indicating developing momentum.
Looking into fiscal 2023, we expect approximately 75 basis points of sequential operating margin expansion in Q1, turned by immediate rebound from the one-time rate true-up in Q4. We're also targeting further margin expansion through fiscal 2023 as we win and ramp new higher margin awards.
Moving to People & Places Solutions. Overall P&PS delivered strong revenue and operating profit results. Q4 net revenue was up 6% year-over-year and up 10% in constant currency. On a constant currency basis, each P&PS region demonstrated net revenue growth and for the full-year, P&PS grew 4% on a reported basis and 7% in constant currency.
Looking deeper into our business units, our advanced facilities unit which benefits from investments in the life sciences, semiconductor and EV supply chains posted another stellar quarter of double-digit revenue and operating profit growth. For the fiscal year that business grew operating profit well north of 25%. We expect our advanced facilities growth rate continue to remain robust during the fiscal year 2023 at approximately 10% despite the strong year-over-year comparisons.
The P&PS international business, Q4 revenue and operating profit was essentially flat year-over-year on a reported basis, but grew double-digits in constant-currency. For the full-year, international operating profit was up 10% year-over-year in constant-currency. Our international business will continue to be materially impacted by FX during fiscal 2023 resulting in flattish reported revenue growth, but it's poised for full-year growth on a constant currency basis.
Total P&PS Q4 gross profit and margins were up year-over-year, but Q4 operating profit up 31% and operating profit as a percentage of net revenue up 275 basis-points, driven by revenue growth and mix as well as lower labor cost during the quarter. Full-year People & Places operating profit was up 5.5% on a reported basis and up 10% in constant-currency with operating margins up 13.2%, up 20 basis points versus year-ago.
In terms of PA's performance, PA Q4 revenue declined 7.7% year-over-year in US dollars, but grew 9% in pound sterling. Q4 adjusted operating profit margin was 19.4% during the quarter due to continued lower utilization and investments in pipeline pursuit. As Bob mentioned, PA Consulting has been successful winning the large clinic award with the MOD for which we expect to show benefit later in 2023.
We continue to target double-digit revenue growth on a constant currency basis with operating margins returning to above 20% throughout 2023 driven by improved utilization. Our non-allocated corporate costs were $28 million down year-over-year as we benefited from lower incentive costs and to a lesser extent from a positive currency impact on our supported cost and other benefits.
We now expect non-allocated costs, corporate costs to be $190 million to $210 million for fiscal 2023, which are slightly higher than fiscal year 2022, as we expect higher incentives costs on a year-over-year basis.
Now turning to Slide 13 to discuss our cash flow and balance sheet. Cash flow generation continued to be strong. Free cash flow was $230 million in Q4 and included $12 million related to transaction costs and other items. On a full year basis, reported cash flow was $347 million, that included the net $475 million of cash outflows related to the previously announced Impex [Phonetic] settlement, the first $55 million repayment of CARES Act payroll tax deferral and a net $4 million cash benefit related to other items.
Excluding these items, free cash flow conversion to adjusted net income was 97% for the year. For fiscal 2023, we expect two items to impact cash level and approximately net $15 million of further cash outflows from restructuring transaction and other related costs and a final repayment of $60 million of CARES Act payroll tax deferral benefits.
Excluding these items, we anticipate again to achieve 100% free cash flow to adjusted net earnings in fiscal 2023. We're also continuing to evaluate further real estate opportunities given our developing insight as towards longer-term needs given the hybrid work environment and we will update on our Q1 earnings call with further developments in this regard.
During the quarter, we repurchased approximately $31 million of shares and for the full-year, we repurchased $282 million. After September, we have continued to be actively purchasing shares was approximately $135 million repurchased as of last week. As we have said before, we will remain agile and opportunistic in repurchasing shares as we see disruption in the market.
We ended the quarter with cash of $1.1 billion and gross debt of $3.4 billion, resulting in a $2.3 billion of net debt. Our Q4 net debt to 2023 expected adjusted EBITDA of approximately 1.6 times is a clear indication of a continued strength of our balance sheet. As of the end of Q4, approximately 60% of our debt is tied to floating rate debt and as a result, we are expecting incremental interest cost going-forward which we have incorporated into our outlook. As of the end of the fourth quarter, our weighted average interest rate was approximately 3.6%.
Early in the fourth quarter, we entered into a notional $500 million interest rate lock at a rate of 2.7% as related to a planned future fixed rate issuance. The mark-to-market benefit from in-the-money interest rate lock is currently recognized in other comprehensive income, but will offset interest expense of our future expected fixed income issuance.
Also in early October, we redeemed $481 million of private notes at par. In the appendix on Slide 16 of this presentation, we included additional detail related to our debt maturities, interest rate derivatives and quarterly interest expense. Finally, given our strong balance sheet and free cash flow, we remain committed to our quarterly dividend which we announced at the end of the fourth quarter of fiscal 2022 and paid on October 28.
I will now turn the call back over to Bob.
