SRG Global has lifted its operating profit guidance for the 2023 financial year after securing more than $1 billion worth of work and acquiring a new business.  Steered by David Macgeorge, the engineering firm announced it had upgraded its earnings before interest, taxes, depreciation, and amortisation guidance to the range of $79 million to $80 million for FY23.The bolstered guidance range is up from SRG’s previously increased EBITDA range of between $72 million to $75 million for FY23, announced in Febuary. The company’s initial FY23 EBITDA range was not disclosed but SRG previously said it expected the result ot be 25 per cent high than FY22’s $57.2 million figure. The $57.2 million ourcome for FY22 was at the top end of its guidance range, which was up significantly from its $46.1 million result in FY21.  SRG said its most recent guidance upgrade includes the EBITDA contribution of between $4.5 million and $5 million from its recently acquired Asset Care business.Earlier this year, SRG locked in a $80 acquisition of ALS’ subsidiary Asset Care, which is an asset integrity and reliability services outfit.The acquisition was bank rolled predominantly by a $51.4 million equity raising and share purchase plan, with the remaining funds procured from a $30 million bank loan and existing cash.At the time of the acquisition in February, SRG anticipated additional revenues of $135 million for FY23 by taking on Asset Care.“The integration of the Asset Care business is proceeding exceptionally well with positive feedback received from the client base in line with the strategic rationale for the acquisition,” SRG said in the statement.“The internal operating model and working relationships have been embedded across the business with many cross-selling opportunities already identified and multiple examples of new work as a combined company have already commended.”To date in FY23, SRG has won more than $1 billion worth of work through its asset maintenance, mining services and engineering and construction divisions.In March, the engineering firm won a $55 million contract from Fortescue Metals Group to construct a haul road for the mining giant’s autonomous truck fleet.SRG will construct a 21-kilometre haul road at the existing Eliwana Mine site in the Pilbara.Earlier that same month, SRG secured $50 million worth of work from BHP Iron Ore, BHP Nickel West and Northern Star Resources for a suite of infrastructure work.SRG was also recently selected to construct the $853 million Edith Cowan Unicity campus to be located in Perth’s Yagan Square.Mulitplex awarded the $120 million contract to SRG to design, supply, and install specialist-engineered curtain wall facades and structures works at the campus.“The company has secured more than $1 billion of new work in FY23 and is well positioned for long-term sustainable growth into the future with a large pipeline of further opportunities and multiple organic levers to grow the business moving forward,” SRG said.At market close, SRG shares last traded at 74 cents, up 2.78 per cent.
