Analysis: Castex Technologies Limited (erstwhile Amtek India Limited)

Modified on January 16, 2019

This article provides fundamental analysis of Castex Technologies Ltd (erstwhile Amtek India Ltd), a manufacturer of iron cast automotive components in India


Castex Technologies Ltd (erstwhile Amtek India Ltd)

Q: Hi Vijay,

Please share your views on Amtek India Ltd. With the current share price at a multi-year low (Rs. 46.5), it is trading at 0.51 times its book value. The Company has had consistent profit growth of over 30% in the last 5 years. The promoter holding has also increased. I do not understand why the share price has been battered over past months.

Is this a good pick for a long-term investor?


Author’s Response

Thanks for writing to me!

Share price of any company may be reflecting many things, which might be related or completely unrelated to the company. Therefore, I would not comment on the stock price movement of Amtek India Ltd. However, I would try to analyse the business dynamics of Amtek India Ltd and recent developments:


Financial Analysis of Castex Technologies Ltd / Amtek India Ltd:

Amtek India Ltd equity analysis research report

Amtek India Ltd has witnessed good growth rate of 20-25% over last decade (2005-14). The growth is healthy, as the company has not compromised on profitability margins in its quest to chase higher sales targets. Operating profit margins are stable at 28-30% and net profit margins are stable at 8-9%.

Tax Rates:

Amtek India Ltd has been paying tax at a consistent rate of 30-32%, which is almost equal to corporate tax rate in India. It is a good sign.

Timely Conversion of Profits into Cash:

Castex Technologies Ltd has been able to convert its profits into cash, as its cumulative cash from operations (CFO) over 10 years (2005-14) is INR 2,569 cr. against cumulative profit after tax (PAT) of INR 1,430 cr. Receivables days have improved from 71 days in FY2011 to 65 days in FY2014. This is another good sign as the profits are not being stuck in working capital/bad receivables accounts.

Operating Efficiency Analysis of Castex Technologies Ltd / Amtek India Ltd:

When we try to see the operating efficiency of Amtek India Ltd, we come to see the problems the company faces. Its asset turnover is very low, or I should say poor!! Its asset turnover is 0.5, which indicates that for every INR 1 increase in sales, it needs to put INR 2 in its fixed assets.

This can be visualized from the comparison of net fixed assets and sales of Castex Technologies Ltd. In FY2014, it required assets of about INR 5,500 cr. to generate sales of about INR 3,000 cr. An investor can easily assume how much more money Castex Technologies Ltd would need to keep on investing in its assets to generate future business growth. It is a very capital-intensive business.

Let us analyse Amtek India Ltd from another perspective. In FY2014, Amtek India Ltd, earned profit before tax of INR 361 cr. from assets of INR 5,500 cr. This is a pretax yield of 6.5%. If someone invests INR 5,500 cr. in a bank fixed deposit (FD) and then given current FD interest rates of 9-10%, she can easily earn about INR 500-550 cr. pretax, without doing anything. Why take the pain of running a huge company!

Further advised reading: When a company should sell all assets and invest money in FDs?

You may read about some of the other companies, which have such low returns on their assets that the company might be better off selling all its assets and investing the money in bank fixed deposits:

Anyway, keeping the comparison of investing in FD versus running a company, Amtek India Ltd needs to deploy huge amount of capital to generate its revenues. As we saw that its operating profits are not sufficient to satisfy its cash guzzling huge investment requirements due to low asset turnover, it needs to find other sources of cash. Like most companies, Amtek India Ltd seems to have relied on debt to fund its cash requirements.

Increasing Debt Levels of Castex Technologies Ltd / Amtek India Ltd

Debt of Amtek India Ltd has increased from INR 156 cr. in FY2005 to INR 5,186 cr. in FY2014. A 33 times increase in debt..!! During the same period, its sales grew from INR 347 cr. (FY2005) to INR 2,991 cr. (FY2014). An increase of only 8 times in sales. This is an example of very poor operating efficiency. We can clearly see what impact a low asset turnover can have on any company. No wonder Castex Technologies Ltd has eroded shareholder’s wealth during this period (2005-14).

This high debt level is going to put the company in deeper issues in case Castex Technologies Ltd is not able to sustain its growth levels, which in turn would require further investment in assets. This would need more cash for which Amtek India Ltd might need to rely on more debt. It seems that unless Castex Technologies Ltd improves its assets utilization efficiency, it might land up in debt trap, which would be detrimental for its shareholders.

Erosion of Shareholder’s Wealth:

During last decade (2005-14), Amtek India Ltd retained profits of INR 1,397 cr. however; its market capitalization increased by only INR 951 cr. during the same period. It indicates that wealth of only INR 0.68 was generated for every INR 1 retained by the company. This is not a desired characteristic of any investment.Read: 3 Simple Ways to assess the Margin of Safety in a Stock

Acquisition of Kuepper group of Germany:

Last year Amtek India Ltd acquired Kuepper, a German auto component maker. Acquisitions are always filled with challenges of integration and more often than not, acquisitions fail and thus turn out to be wealth destroyer for shareholders. It remains to be seen how well Amtek India Ltd is able to integrate Kuepper into its ambit and gain some synergies, if any.

If Castex Technologies Ltd has acquired Kuepper for new technology to improve its operating efficiency and it is able to use it successfully, then Castex Technologies Ltd  may see a new phase and might lead to re-rating of its stock. However, if it turns out to be another story of expensive acquisition gone wrong, then ultimately shareholders of Amtek India Ltd will suffer.

These are my views about Amtek India Ltd. However, you should do your own analysis before you take any investment related decision about Amtek India Ltd.

"Peaceful Investing": My Stock Investing Approach

“Peaceful Investing” approach is the result of my more than a decade of experience in equity markets. This approach helped me invest even when I had a full-time corporate job and could not spare a lot of time for stock analysis. During my investing journey, I have faced all the common challenges of the investors, the biggest one being “scarcity of time”. “Peaceful Investing” approach keeps in mind that an investor will have limited amount of time to spare for stock investing. 

The objective of “Peaceful Investing” approach is the selection of such stocks, where once an investor has put in her money, then she may sleep peacefully. Therefore, if later on, the stock prices rise, then the investor is happy as she is now wealthier. On the contrary, if the stock prices fall, even then the investor is happy as she can now buy more quantity of the selected fundamentally good stocks.
