On the record
Checkpoint: Zensar Technologies stake-sale deal closes or collapses
The call
Mastek is profitable and still winning UK government work, but growth is stalling, a founder sale to Zensar is unresolved, and AI pricing pressure is squeezing the model that pays the bills.
Mastek provides IT work and tech support to UK government agencies like the police and financial regulators, bringing in $421 million a year. It is getting harder to compete because giant firms like Infosys and TCS are winning the same government contracts Mastek used to get, and AI tools are reducing the number of hours the company can bill clients for the same work, which is how Mastek makes most of its money. The biggest unknown is whether the company's founders will complete a sale to a rival called Zensar, which would turn Mastek into a subsidiary rather than an independent business and could wipe out employee stock options in the process.
Why
01
AI pressure: AI coding assistants and automation tools. AI is cutting billable hours in Mastek's time-and-materials model; management flagged this as an FY27 margin headwind. Could AI do the core job? Yes, likely.
02
Bigger players: Infosys, TCS, Capgemini, Wipro, HCLTech, Cognizant. Bigger rivals with deeper AI budgets are winning bids on Mastek's own turf; Mastek lost an NHS-tier contract. Could a giant copy it? Yes, easily.
03
What protects it. UK security clearances and entrenched contracts with FCA and Home Office create switching friction, not a wall.
What would change this call
Whether the Zensar Technologies stake-sale deal closes and on what terms. Shows if Mastek stays independent or becomes a subsidiary under integration.
Outcomes of the next 2-3 UK public-sector bids (FCA, Home Office, similar tier). Shows whether Infosys/TCS displacement of Mastek is accelerating or moat holds.
Q2 FY27 revenue growth rate versus Q4 FY26's 3.6% YoY and Q1's ~7-8%. Shows whether growth deceleration is bottoming out or structurally worsening.

Questions people ask
- Is Mastek profitable in 2026?
- Yes. Mastek posted FY26 (year ended March 31, 2026) consolidated revenue of ₹3,698.8 crore (about $421.2M), up 7.0% YoY, with PAT of ₹404 crore, up 7.5% YoY, and a 15.8% EBITDA margin, per its July 2026 investor disclosures.
- Is Mastek being acquired by Zensar?
- Talks are ongoing but unresolved. Since December 2025, Mastek's promoter group has been in discussions to sell an 18-20% stake, with Zensar Technologies the reported frontrunner in a deal valued up to $850-900M; as of May 22, 2026, the deal had still not closed.
- Did Mastek lose a major contract to a competitor?
- Yes. Mastek reportedly missed out on a $1.6 billion UK NHS IT modernization contract that went to Infosys instead, cited in February 2026 reporting as a factor behind the promoter's decision to explore selling its stake.
- Could AI replace Mastek's services?
- Partially. Mastek management named AI-led pricing pressure on its traditional time-and-material staffing model as an FY27 headwind, per its April 21, 2026 earnings call, while AI/automation/data still made up only about 12.5% of FY26 revenue.
- Who is Mastek's biggest competitor?
- Infosys is the most concrete named threat, having won the $1.6 billion NHS contract Mastek lost (reported February 2026); Mastek also competes against TCS, Capgemini, Wipro, HCLTech, Cognizant and mid-tier peers Zensar, Persistent Systems and Coforge.
- Is Mastek's revenue growth slowing down?
- Yes. Mastek's YoY revenue growth fell from 16.1% in FY25 to 3.6% by Q4 FY26 (quarter ended March 31, 2026), a deceleration flagged in a May 22, 2026 commentary as a structural growth problem despite AI-deal messaging.
