The comparison is best framed across two axes:

This difference matters.

Tech Mahindra can produce rapid earnings growth because margin was previously low.

Persistent can produce rapid earnings growth because revenue itself is compounding quickly.

Q1 FY27 comparison

Tech Mahindra has moved beyond a cost-cutting turnaround

For several quarters, the Tech Mahindra thesis centred primarily on margin repair.

Q1 FY27 changed that somewhat.

Revenue grew:

• 6.6% YoY in constant currency,
• 2.6% QoQ in constant currency.

Management also said all verticals delivered year-on-year growth.

That means the turnaround is increasingly supported by top-line growth rather than cost control alone.

The margin recovery is substantial

When EBIT grows 53.3% while revenue grows 17.7%, operating leverage is clearly working.

Tech Mahindra is extracting much more profit from each incremental rupee of revenue.

How margin recovery creates earnings growth

A simplified IT-services profit equation is:

Revenue × EBIT margin = EBIT.

If both revenue and margin rise simultaneously, EBIT can grow far faster than sales.

That is exactly what happened at Tech Mahindra in Q1.

This is why turnaround stocks can produce rapid earnings growth even without Persistent-like revenue growth.

Persistent starts from a stronger operating base

Persistent reported a 16.0% EBIT margin.

That remains about 160 basis points above Tech Mahindra's 14.4%.

It also grew substantially faster.

This is a powerful combination:

higher growth + higher current margin.

That combination is one of the reasons Persistent trades at a premium.

Persistent's 25-quarter streak matters more than one growth number

A 25-quarter streak changes the quality of evidence.

The market no longer needs to ask whether Persistent can grow.

It needs to ask how durable that growth remains at a larger scale.

The denominator is still an advantage for Persistent

Persistent generated $452.4 million of quarterly revenue.

Tech Mahindra generated $1.66 billion.

A $100-million annualised revenue addition therefore has a much greater percentage impact on Persistent.

This makes mid-teens growth more achievable.

But denominator size alone cannot explain a 16.5% versus 6.6% growth gap.

Persistent is also winning in faster-growing service categories.

Digital engineering is Persistent's structural advantage

Persistent's business is strongly oriented toward:

• software engineering,
• cloud-native development,
• data platforms,
• AI-led product development,
• enterprise modernisation,
• platform transformation.

These areas sit close to current enterprise spending priorities.

AI adoption often requires modern applications and data foundations before models can create business value.

Tech Mahindra's structural advantage is telecom and complex operations

Tech Mahindra has deep historic capabilities in communications.

That can become increasingly relevant as AI enters:

• network optimisation,
• AIOps,
• service assurance,
• customer support,
• network digital twins,
• edge infrastructure.

The company is also diversifying more aggressively into:

• payments,
• healthcare,
• aerospace and defence,
• financial services.

All-vertical growth is an important Tech Mahindra signal

A telecom-heavy technology vendor is more vulnerable if communications spending weakens.

Management's Q1 statement that all verticals grew year on year suggests diversification is progressing.

The number of $50-million-plus clients also increased by seven.

This indicates stronger account mining rather than dependence only on new logos.

The deal-win numbers look similar but are economically different

The headline difference is only around $68 million.

But Persistent's number is unusually concentrated.

One deal accounts for at least 56.7% of Persistent's TCV

The simple calculation is:

$650 million ÷ $1.1462 billion ≈ 56.7%.

Because the company disclosed the contract as worth more than $650 million, the true share is slightly higher.

This does not diminish the strategic value of winning the deal.

It simply means $1.146 billion should not be annualised as a normal quarterly booking rate.

Persistent's ACV provides a useful second lens

Annual contract value was $536.8 million.

ACV helps reduce distortion from multi-year contract duration.

For a 6.5-year mega deal, TCV can be enormous even though the annual revenue contribution is much smaller.

Investors should therefore track both:

• TCV,
• ACV.

Tech Mahindra's three-quarter deal streak is arguably the cleaner trend

Q1 was the company's third consecutive quarter with more than $1 billion of deal wins.

This matters because one record quarter can be luck.

Three strong quarters begin to indicate a repeatable sales engine.

Free cash flow supports Tech Mahindra's recovery quality

Tech Mahindra generated approximately $167 million of Q1 free cash flow.

USD PAT was approximately $154 million.

A simple analytical conversion ratio is:

$167 million ÷ $154 million ≈ 108%.

This is not a company-labelled FCF-conversion percentage.

But it shows that accounting profit is being converted into cash.

Margin recovery without cash flow would be less convincing

A turnaround can look strong on the income statement while receivables absorb all cash.

Tech Mahindra's Q1 does not show that pattern.

Days sales outstanding stood around 84 days.

Cash and cash equivalents were approximately ₹9,695 crore.

Persistent's operating earnings were stronger than PAT growth

Persistent reported:

• EBIT +32.7% YoY,
• PBT +12.2%,
• PAT +13.7%.

The company said quarter-on-quarter PBT and PAT were affected by forex losses.

That makes EBIT a cleaner measure of underlying delivery execution for Q1.

The AI comparison is primarily about business architecture

Neither company currently gives a directly comparable single AI-revenue percentage for Q1.

Tech Mahindra discusses:

• domain-specific AI,
• sovereign AI,
• agentic development,
• AIOps,
• network digital twins.

Persistent focuses heavily on:

• AI-led engineering,
• enterprise context,
• software modernisation,
• data and cloud foundations.

Persistent may be closer to software-product creation

Its engineering heritage means Persistent often works directly on:

• product architecture,
• software lifecycle,
• platform development,
• AI integration into products.

This can create high growth when enterprises redesign software around AI.

Tech Mahindra may be closer to domain operations

Its telecom and enterprise-operations experience creates opportunity to apply AI directly to:

• networks,
• customer operations,
• managed infrastructure,
• industry-specific workflows.

The two AI models are therefore complementary rather than identical.

The Nagarro transaction adds upside and risk to Persistent

Persistent is pursuing a voluntary public takeover offer for Nagarro.

As of September 1, 2026:

• the initial acceptance period runs until September 17,
• Persistent has already secured approximately 22% of Nagarro,
• management and employee shareholders representing about 15% intend to tender,
• the threshold is 50% plus one share.

The transaction remains incomplete.

Nagarro is therefore excluded from Persistent Q1 figures

No Nagarro:

• revenue,
• EBIT,
• employees,
• cash flow

should be added to Persistent's Q1 FY27 numbers.

The proposed combination would create a much larger AI-led engineering platform, but investors must wait for closing.

The acquisition could narrow Tech Mahindra's scale advantage

Persistent and Nagarro together would create a company approaching roughly $2.9 billion of combined annual revenue under transaction materials.

That would materially increase Persistent's European footprint and engineering scale.

But acquired scale comes with:

• financing,
• integration risk,
• interest cost,
• cultural execution.

It should not be valued as free growth.

Tech Mahindra's turnaround has lower transformational M&A dependency

Tech Mahindra's current earnings recovery comes primarily from:

• better utilisation,
• portfolio discipline,
• cost control,
• new-deal growth,
• account mining.

This produces a narrower range of M&A outcomes than Persistent currently faces.

Valuation: Persistent still commands a major premium

Persistent's earnings multiple is around 55% higher than Tech Mahindra's on this same-provider August 31 basis.

Its book multiple is more than twice as high.

Persistent's premium has stronger fundamental support than many high-P/E IT stocks

The company has:

• 16.5% CC growth,
• 25 consecutive sequential-growth quarters,
• 16% EBIT margin,
• 26%+ Bull Run ROE,
• 33% Bull Run ROCE.

The premium therefore reflects a real business-quality gap rather than only market enthusiasm.

But valuation still matters

A high-quality company purchased at too high a valuation can produce mediocre returns.

Persistent needs continued high growth to absorb a 40x-plus earnings multiple.

If revenue growth declines materially before the multiple compresses, valuation risk rises sharply.

Tech Mahindra's valuation already assumes meaningful recovery

Tech Mahindra is no longer a deep-value turnaround stock.

A roughly 28x trailing P/E means the market has already rewarded:

• 330-bps margin expansion,
• strong deal wins,
• return of revenue growth.

The next phase needs continued margin and revenue execution.

The investment hurdle is different for each

Tech Mahindra needs to:

• move EBIT margin further toward stronger large-cap peers,
• sustain mid-single-digit or better growth,
• keep deal wins above $1 billion,
• maintain cash conversion.

Persistent needs to:

• maintain double-digit organic growth,
• keep margins near or above 16%,
• diversify mega-deal concentration,
• execute Nagarro successfully if the offer closes.

Bull Run market snapshot

The return comparison is surprisingly close over six months despite Persistent's much stronger revenue growth.

Tech Mahindra's margin recovery has already attracted meaningful investor interest.

Why Bull Run P/E and fresh August 31 P/E differ

Bull Run's August 25 database snapshot showed higher trailing P/E values for both companies.

Fresh same-provider August 31 ratios use updated trailing earnings and later share prices.

The article therefore:

• preserves Bull Run's internal August 25 market snapshot,
• uses fresh August 31 external ratios for the primary current valuation comparison.

This avoids mixing dates without explanation.

Tech Mahindra vs Persistent Systems: category-by-category

Which is stronger in 2026?

Persistent Systems remains the stronger pure operating-growth franchise.

It offers:

• 16.5% CC growth,
• 25 consecutive sequential-growth quarters,
• 16% EBIT margin,
• strong return ratios,
• deep AI-led digital-engineering exposure.

Tech Mahindra has the more powerful earnings-recovery setup.

It offers:

• 6.6% CC growth after a weaker period,
• 330-bps margin expansion,
• 53.3% EBIT growth,
• three consecutive $1-billion-plus deal quarters,
• strong FCF conversion,
• a materially lower current P/E.

The current comparison is:

Tech Mahindra = improving large-cap turnaround where earnings can grow quickly through margin recovery.

Persistent = superior long-duration digital-engineering compounder whose premium valuation demands continued high growth.

What to monitor next

• Tech Mahindra EBIT margin: the key turnaround metric.
• Tech Mahindra CC growth: must remain broad-based rather than return to low single digits.
• Tech Mahindra deal wins: watch whether the $1B+ streak continues.
• Tech Mahindra $50M+ clients: continued growth indicates deeper account mining.
• Tech Mahindra FCF: strong cash conversion should accompany the margin recovery.
• Persistent sequential growth: extend the 25-quarter streak.
• Persistent ACV: important for normalising long-duration TCV.
• Persistent mega-deal conversion: the $650M+ agreement must ramp over several years.
• Persistent EBIT margin: salary hikes and M&A expenses could create pressure.
• Nagarro offer: acceptance and eventual integration can materially change Persistent's scale and leverage.
