Four Days After the Fiscal Year Closed

On August 31, 2026, Northern Technologies International Corporation closed a fiscal year in which its sales had reached records and its profit had not. The quarter that ended three months earlier had brought a record $24.2 million in sales and a net loss of $263,000.

Four days later, the board changed chief executives.

On September 4, the directors of NTIC elected Gautam Ramdas, 53, president and chief executive officer, replacing G. Patrick Lynch, who had held the chief executive's seat since January 2006 and now became chairman. The 8-K says the change was part of a succession plan and not the result of any disagreement. Ramdas was no outsider. He had been at the company since October 2005, and the filing credits him with leading the diversification of its Zerust corrosion-prevention line beyond automotive and industrial customers into oil and gas, petrochemicals and renewable energy. It lists patents, work with the American Petroleum Institute and federal pipeline regulators, and a hand in strategic planning. Before NTIC he did supply-chain and strategy consulting at IBM and PricewaterhouseCoopers; he holds an MBA from Michigan's Ross School and an engineering degree.

The Quarter That Would Not Turn

On July 9, Lynch had told investors what chief executives rarely volunteer. Gross margin had fallen 477 basis points to 33.6 percent. The conflict in the Middle East, including the Strait of Hormuz, had driven up the cost of key raw materials, and price competition had squeezed the company's bioplastics line. Reaching the profitability the company had planned for was "taking longer than expected".

He named a lever in the same statement: more sales of the higher-margin oil-and-gas products.

That lever had a name attached to it.

A Forecast From 2019

In December 2019, Business View Magazine interviewed Ramdas, then vice president of global market development, about the oil-and-gas division. The magazine listed customers including BP, Chevron, Enbridge and Petrobras, and Ramdas described a network of about 29 joint ventures, half-owned by NTIC, reaching more than 70 countries. Zerust had worked on about 300 storage tanks worldwide, he said, while the United States alone held between 700,000 and a million. He called the company's position "scratching the tip of the iceberg" and put a number on what might follow: "five years from now, instead of 300 tanks, we might say 3,000 tanks or 30,000 tanks".

He said might. The record since is only partial. NTIC's latest quarterly filing does not report a tank count. It reports dollars. Oil-and-gas sales rose 72.3 percent in the third quarter, to $2.2 million, and 67.3 percent over nine months, to $7.3 million, lifting the line to 10.5 percent of sales from 7.0 percent a year earlier. The filing credits demand primarily in the Middle East and Brazil. In 2019 Ramdas had said Petrobras was the division's largest client for its first few years.

The Engine Is Volatile

The growth carries a warning, and the company wrote it down. The same filing says oil-and-gas sales "will continue to remain subject to significant volatility from quarter to quarter". It adds that the Middle East conflict may increase the volatility of customer demand, project timing and order patterns.

The region that fed the fastest-growing line is also the region Lynch blamed for the cost of the materials behind the thinner margin. The filing does not claim the two effects cancel out. It does not say they won't.

The board's language about its pick was practical. Lynch credited "Gautam driving our global market development and oil and gas expansion". Richard Nigon, the lead independent director, said the promotions gave NTIC "proven leaders with deep operational expertise to drive execution across our businesses." The terms were specific: a $520,000 base salary, a promotional option on 15,278 shares at $7.99, and 18 months of severance. Lynch stays on as an employee for up to three years.

The Argument He Put In Print

One day before the board acted, Data Center Knowledge published a byline under Ramdas's name. Its subject was not oil. It was the construction of AI data centers, and what he called a blind spot. "Corrosion is still widely treated as a maintenance issue" he wrote, arguing that it starts as equipment moves through factories, ports and storage yards long before a facility switches on. His warning was blunt: "By the time it is discovered, the opportunity to prevent it has often passed."

The piece pitches an old product at a new buyer. In 2019 his division had started with offshore platforms and moved to refineries and terminals. In September he was writing to the builders of liquid-cooled server halls.

Outside NTIC, the filing says, he co-founded Magzter, a digital publishing platform with 88 million downloads that VerSe Innovation acquired in April 2024. Inside it, he had once observed a branding problem: "Over the years, we found more people know us as the Zerust guys than those guys from NTIC".

The Quarter He Did Not Close

The fiscal fourth quarter ended August 31, four days before Ramdas took the seat. In July, Lynch said he expected stronger, more profitable results for it. As of this writing, NTIC has filed none.

The base he inherits is not small. Net sales at the joint ventures NTIC does not consolidate rose 15.1 percent in the third quarter to $26.7 million, and the income NTIC drew from them rose 12.2 percent to $2.6 million. When it does, the figures will be the first published under Ramdas's name, produced mostly before his title arrived. The margin question that sent the previous chief executive to investors in July is now his to answer.
