The Mystery of Why PSUs Trade for Less Than They're Worth

The body on the balance sheet

Every investigation starts with a body. This one starts with a bank that looks healthier than its price tag suggests.

State Bank of India is not showing up like a distressed lender. In its FY26 result release, SBI reported a 0.39% net NPA ratio, 1.49% gross NPA ratio, and 15.40% CRAR. These are not the vitals of a patient gasping for oxygen.

SBI's deposits-plus-advances business is roughly 1.7x HDFC Bank's, yet SBI's market cap is still lower than HDFC Bank's. Why?

The discount did not disappear:

That is the first clue. The market is not just scoring asset quality. It is pricing control.

The easy explanation for the discount is: "PSUs are badly run." The more uncomfortable explanation is that the controlling shareholder can be perfectly rational and still not be optimizing for you.

The obvious suspect has a weak alibi

"PSUs are slow." "PSUs have bureaucracy." "PSUs destroy capital." These are not imaginary complaints. Some are earned.

But they are not enough to solve the case. If the discount were only about bad operations, improving operations should steadily erase it. Instead, even after cleaner balance sheets and stronger profitability, the market still asks for a lower entry price.

A good detective does not stop at the first confession. The sharper question is: what risk survives even when the numbers get better?

The risk is custody: who gets to decide what happens with the company's cash, lending book, investment plan, and timing of stake sales?

The dividend tap is not subtle

In a private company, excess cash is a capital-allocation debate. In a PSU, it can become a fiscal-receipts line item.

DIPAM's revised 2024 capital restructuring guidelines say every CPSE – Central Public Sector Enterprise, a company majority-owned by the central government – should pay a minimum annual dividend of 30% of PAT or 4% of net worth, whichever is higher, subject to legal limits. The same document also says predictable interim dividends help the Government receive periodic dividend flows before Budget Estimates are finalized.

That sentence matters. The policy is not just "shareholders deserve dividends." It is also "the Government needs predictable cash flow."

Dividends are not bad. Forced or politically timed payouts are different. They reduce management's freedom to retain capital when reinvestment would create more long-term value.

The company has more than one job

A listed private company usually has one clean commercial target: grow value for shareholders within the law.

A PSU can have two targets at once: earn a return and help execute public policy. Sometimes those goals overlap. Sometimes they fight.

Take priority-sector lending. RBI requires all domestic banks – private and public alike – to direct part of their lending to designated priority sectors. So the rule itself is not PSU-only. But when the government owns the bank, investors worry about what happens on the day a policy goal and a profitable lending decision pull in opposite directions. Which one wins?

That is not a conspiracy theory. It is simple incentives. The market sees a company that has to earn profits and serve policy at the same time – and it pays less for that company.

The seller is always in the room

There is another reason investors hesitate to pay full price: the Government may want high valuations, but it also needs to raise money on the Budget's calendar – not the market's.

Budget documents show how unstable that timetable can be. For 2025-26, India's disinvestment target was Rs 47,000 crore; the revised estimate was Rs 33,837 crore, or about 71.9% of the original target.

A shareholder who may sell because the Budget needs money is not the same as a founder who sells because the business has reached fair value. The market knows the difference. It calls it overhang.

The twist: why defence PSUs escaped the script

The exception is defence.

Defence PSUs such as BEL and HAL show why the discount is not automatic. When government policy creates orders, protects domestic procurement, and expands the addressable market, political motive and shareholder motive can point in the same direction.

India's defence purchase rules put homegrown products first – categories like Buy Indian (IDDM) get top priority, and official indigenisation lists phase out imports of specified items over set timelines. For domestic defence manufacturers, that means a visible pipeline of future orders.

But that is not an automatic buy signal. If the stock price runs ahead of actual delivery – orders converting to revenue, margins holding up – the same story can hurt you. Alignment removes one discount. It does not make an expensive stock cheap.

The verdict

The PSU discount is not a single number. It is a bundle of risks: capital allocation risk, policy-mandate risk, dividend-extraction risk, sell-down risk, and memory of past governance scars.

That is why cheap is not enough. A PSU at a low P/B can be undervalued, or it can be correctly priced for a controlling shareholder whose priorities may change with the Budget, the ministry, or the policy cycle.
