Another Order in Drilling Machines.

Trevi Group 4.7.26 Another Order in Drilling Machines. Trevi Group announced that EDRA signed a contract with NIOC for the production of four full-packaged drilling systems, which should generate USD 93.5M (USD 57.7M for Trevi Group). We confirm our estimates, which had been recently upwards revised, following the strong increase in both 1Q6 sales and profitability. A new contract for EDRA. Trevi Group recently announced an important new contract, signed by EDRA (European Drilling Rig Alliance, which is a joint venture providing full-packaged drilling systems) and NIOC (National Iranian Oil Company). The order consists of four full-packaged drilling systems for a total amount of USD 93.5M, with USD 57.7M for Trevi Group. The group will provide the drilling machines through the fully-owned Drillmec, which currently has an orders backlog of EUR 145.7M, 38% higher than at end-march 26. According to management, Drillmec should post an 89% yoy sales growth in 1H6. 1Q6 results. In 1Q6, the group posted a strong and above than expected growth in sales (EUR 165.2M, +95.5% yoy) and EBITDA (EUR 24.6M, +191.1% yoy), which was mainly driven by the drilling division. By geographic area, the group posted a solid increase mostly in the African and American markets (mainly driven by foundation works). Thanks to the higher value of production, Trevi Group posted a strong growth in the EBITDA margin (from 1.% in 1Q5 to 14.9%), the EBIT margin (from 4.% to 9.8%) and the net margin (from 1.7% to 3.9%). At 1Q6, net debt amounted to EUR 136.3M, higher than that of YE5, due to the higher level of stock related to the increasing sales of the year. Valuation and estimates. We confirm our sum-of-the-parts valuation of the group s two divisions, drilling and foundations, based on a DCF model, pointing to a fair value of EUR 9./share, which was updated in our Corporate Broking Review of 1.6.26. The SOP valuation based on a peers comparison shows a lower value (EUR 8./share) compared with the DCF model, due to our 29E-214E higher implied medium term growth (IMTG). Our model shows that our fair value implies an EPS IMTG of 23.4% vs. 13.5% in the current market price.

Valuation. We confirm our sum-of-the-parts valuation of the group s two divisions, drilling and foundations, based on a DCF model, pointing at EUR 9./share (6% construction and 4% drilling). The SOP valuation based on peers multiples shows a lower value compared with the DCF model, due to our higher 29E-214E implied medium term growth (IMTG). Our model shows that our fair value implies an EPS IMTG of 23.4% vs. 13.5% in the current market price. DCF of the drilling division. Our drilling division valuation is based on a three-stage DCF model: Explicit estimates for the 26E-28E period are based on a 26E NOPAT of EUR 9.8M, with a 26E-28E NOPAT CAGR of 64.6% and a 28E ROCE of 41.6%; Three-stage DCF model for the drilling division. In the second considered period of 29E-218E, we assumed a NOPAT growth rate of 4.8%, with a gradually decreasing ROCE; The last stage is related to terminal value, which is calculated through the perpetual growth rate formula (NOPAT/WACC) on 218E, when we assumed a ROCE in line with WACC at 7.5%, thus a perpetual growth rate of zero. We set the drilling division enterprise value at EUR 284M. Drilling division 26E-8E FCF.

DCF of the foundations division. Our foundations division valuation is also based on a three-stage DCF model: Explicit estimates for the 26E-28E period are based on a 26E NOPAT of EUR 22.3M, with a 26E-28E NOPAT CAGR of 34.9% and a 28E ROCE of 33.5%; Three-stage DCF model for the foundations division. In the second considered period of 29E-213E, we assumed a NOPAT growth rate of 3%, with a decreasing ROCE. In the foundations division, we assumed a shorter competitive advantage period (CAP) than drilling, due to the different competitive positioning and the higher drilling marginal ROCE; The last stage is related to terminal value, which is calculated through the perpetual growth rate formula (NOPAT/WACC) on 213E, when we assumed a ROCE in line with WACC at 7.5%, thus a perpetual growth rate of zero.

Our sum-of-the-parts valuation of the drilling and foundations businesses points to a fair value of EUR 9./share (approx. 39% higher than the current market price), mainly reflecting our recent upwards revised estimates in both the drilling and foundation divisions. At our fair value of EUR 9./share, the 26E P/E is 24.7x; however, if we consider a 26E-28E EPS CAGR of 46%, then it would imply a 26E-28E PEG of.52x and a 28E P/E of 14.4x.

Recent News. A new order in Iran for a total amount of USD 93.5M. Trevi Group has recently announced a new important order in drilling machines, received from the Iranian oil company (NIOC). The order was won by EDRA, the European joint venture created in 22 by Drillmec and two other European players, which aims to participate in tenders of over EUR 2M, offering full-packages of drilling systems with high technological content. The order involves the production of four drilling systems, which allow EDRA to post USD 93.5M total sales, generating USD 57.7M for Trevi Group through the fully-owned Drillmec. The Drillmec orders backlog currently amounts to USD 145.7M, increasing by 38% compared with end-march 26. 1Q6: strong growth in sales and profitability. 1Q6 results.

As reported in our Corporate Broking Review, in 1Q6 (traditionally a weaker quarter given Trevi s business nature), the group posted a strong and above than expected growth in sales (EUR 165.2M, +95.5% yoy) and EBITDA (EUR 24.6M, +191.1% yoy). By division, the sound sales growth rate was mainly driven by drilling, with machines increasing from EUR 4.5M in 1Q5 to EUR 3.1M in 1Q6 and services from EUR 2.9M to EUR 5.8M. In the foundations division, machines were up by 89% yoy to EUR 43.1M and services up by 56% to EUR 83.9M. By geographic area, the group posted a solid increase mostly in the African and American markets (mainly due to foundation works). Thanks to the higher value of production, Trevi Group posted a strong growth in the EBITDA margin (from 1.% to 14.9%), the EBIT margin (4.% to 9.8%) and the net margin (from 1.7% to 3.9%). At 1Q6, net debt amounted to EUR 136.3M, higher than that of YE5, due to the higher level of stock related to the increasing sales of the year. The orders backlog increased from EUR 516.5M at end-25 to EUR 578M. 6

Earnings Outlook. Estimates revision after 1Q6 results. Following 1Q6 results, we had upwards revised our estimates in our last Corporate Broking Review, taking into account the strong sales growth and profitability in machinery and foundations. After the new recent order, we confirm our forecasts, showing the breakdown by division in the following tables.

The foundation works division. In foundation works, we assumed 26E-28E sales CAGR of 1.4%, with the EBITDA margin improving from 12.4% in 25 to 13.9% in 28E. In our forecasts, 26E foundation works sales should rise by 19.5%, after the solid trend in 1Q6 (+56% vs. 1Q5), which benefited from the new orders started in Africa, Middle East and US (the Tuttle Creek dam). In our view, profitability should benefit from an increasing focus on the quality of orders, such as higher prices for a lower number of contracts, with a higher average duration.

In our view, the EBITDA margin should increase from 9% in 25 to 12.5% in 28E, thanks to better economies of scale. We believe that drilling equipment should benefit from the key success that HH-model machines (Hydraulic Drilling) could obtain on the market in the next three years, thanks to the high technology innovation and safety standards. Our estimates already factor in the new order between NIOC and EDRA. We estimate a 26E sales growth rate of 52.5%. 8

According to our forecasts, starting from 27E, a sound free cash flow generation should allow a rebalancing between net debt and equity, with a decrease in the group s debt ratios. In our view, 26E free cash flow should be slightly lower than that of 25, mainly due to the extraordinary level of capex (EUR 35M vs. EUR 23.8M in 25), mostly related to the development of drilling activities (both services and equipments). According to our estimates, operating free cash flow, both in absolute terms and as percentage of sales, should show a sound growth in 27E-28E to 4.9% of revenue in 28E.

As a result of an improving net debt, in our opinion, D/EBITDA should improve from 2.3x in 25 to.8x in 28E and D/Mkt. cap from.7x in 25 to.2x in 28E. 9
