Accenture confirms leadership, Deloitte & EY fastest growing.
PAC published its first vendor rankings by 2023 IT services revenue in the Americas.
Accenture remains the undisputed leader on the American IT Services market. IT service revenue grew 2% in 23 (+20% in 22), with growth slowing down along the year (+5% in Q1, +2% in Q2, +1% in Q3 and -1% in Q4). Like most of its peers, Accenture suffered from decreasing spending in banking, telecom and technology, and from the massive slowdown of the cloud business.
Deloitte managed to close the gap, with +13% in 23 (+20% in 22). Similar to its peers (PwC, EY and KPMG), Deloitte was less impacted by the end of the major cloud transformation programs: the big 4 are less focused on big deals and they are late entrants on the cloud market. By comparison, they are more dependent on ERP transformations and they benefited from the acceleration in SAP and Oracle. Finally, being privately held, they are not submitted to shareholders expectations of short-term savings when market conditions deteriorate; while the big IT services vendors raised the pressure on their resources and conducted some lay-off programs, the big 4 took advantage of the situation to reinforce their skills in selected segments.
IBM grew its IT services revenue by 2% (+9% in 22), with strong growth in the Consulting unit offset by a substantial decrease in the Infra Support business. IBM Consulting reported quite stable growth across the year.
Tata Consultancy Services grew 3% (+19% in 22), with growth slowing down along the year (+10%, +5%, 0%, -3%). Cognizant decreased 1% (+6% in 22) with a consistent (weak) performance along the year (-1%, -2%, -1%, -2%). Infosys grew 1% (+15% in 22), again with growth slowing down (+6%, +2%, +1%, -5%).
General Dynamics Information Technology grew 3% (+1% in 22), PwC reported +7% (23% in 22), Leidos grew 7% (+5% in 22). GDIT and Leidos (like Peraton below) benefited from the healthy public sector & defense market.
HCLTech and Capgemini fight for the 10th place. Including BPO and/ or engineering services, HCL leads; including management consulting, Capgemini leads. However the 23 performances were quite different: while HCL grew 7% in 23 (+9% in 22), won 3 places and managed a stable growth (+10%, +7%, +4%, +7%), Capgemini reported a 1% decrease (+14% in 22) with a continuous slow down (+6%, 0%, -4%, -7%).
Kyndryl decreased 5% (-3% in 22), Peraton grew 6% (+6% in 22), Dell Technologies decreased 10% and finally EY grew 13%, thus entering the top 15.
Behind, 7 vendors fight for a place in the Top 20: NTT DATA, Wipro, Oracle, CACI International Inc, DXC Technology, CGI and KPMG.
Note: For this ranking we excluded BPO. Including BPO, 3 specialists would enter the top 15: ADP (ranking 6th), Fiserv (7th) and FIS (11th); yet all 3 operate on very specific markets (payroll & HR resp. payment).
