IGI Q1 FY27: Volume-led growth, higher margins, and AGL adds a new gemstone lane

International Gemological Institute Limited started FY27 with a strong quarter on consolidated numbers. For the quarter ended June 30, 2026, certification revenue rose to INR 3,598 million, up 23% year on year, while total reported volumes increased to 3.56 million reports, up 17%. Profitability expanded faster than revenue. EBITDA (excluding other income) grew 29% year on year to INR 2,238 million, with the EBITDA margin improving to 60.4% from 57.7% a year ago. PAT rose 31% year on year to INR 1,657 million, and PAT margin expanded to 44.7%.

Management attributed the growth to broad-based momentum across LGD loose stones, LGD jewelry, and an increasing contribution from gemstones and other certifications. The acquisition and consolidation of American Gemological Laboratories (AGL) was called out as an incremental driver, adding about 3% to consolidated revenue growth and about 2% to EBITDA growth in the quarter.

What drove Q1 growth: LGD remains the core engine

The quarter’s revenue mix continued to be led by lab-grown diamond certification. On consolidated certification revenue of INR 3,598 million, LGD loose stones contributed INR 2,095 million and remained the largest segment. LGD jewelry, a smaller base but faster-growing vertical, increased sharply to INR 281 million. In management’s framing, the lab-grown value chain is entering a volume-scale phase, which structurally increases certification needs as throughput rises and SKU-level jewelry certification expands.

Natural diamonds were described as a strategic priority, even if the near-term growth was modest in Q1. On consolidated numbers, ND loose stones were INR 504 million and ND jewelry was INR 514 million. Management said work is underway to gain market share in natural diamond loose stones through new customer acquisition and higher share of wallet.

Average realized price (ARP) per report improved to INR 1,010 versus INR 963 in the year-ago quarter. Management clarified that ARP is influenced by mix and carat size per report. They also stated that AGL consolidation contributed around 2 to 3 percentage points of ARP improvement in this quarter.

AGL changes the narrative: gemstones become a third leg

A key strategic takeaway from the quarter was the clearer positioning of AGL. Management described AGL as a leader in gemstone certification in the US and a way for IGI to expand into colored stone gemstones beyond diamonds. In Q1 FY27, consolidated gemstones and other certification revenue rose to INR 204 million versus INR 67 million in Q1 FY26.

On the earnings call, management said the gemstone market is regional on sourcing, but the main high-end consumer is in the US. The company’s stated plan is to take AGL’s capabilities and extend them using IGI’s global platform, starting with initiatives such as collection windows and mobile laboratories, beginning with Jaipur and then moving to other relevant geographies.

This matters for two reasons. First, it expands IGI’s total addressable market while still staying within third-party certification where the company’s core competencies sit. Second, it creates potential cross-sell opportunities where IGI already has a presence across diamond markets.

Costs, seasonality, and how management sees margins

Sequentially, Q1 FY27 was softer than Q4 FY26. On a QoQ basis, consolidated volumes dipped 2%, and consolidated EBITDA declined 5% while PAT declined 8%. Management attributed this to a seasonally strong January to March quarter that benefits operating leverage. The CFO stated that Q1 margins are a more representative indicator of the sustainable run rate.

The company also flagged higher expenses due to increased headcount, AGL consolidation, and marketing spends. Marketing became a more visible part of the story this quarter. Management discussed moving from primarily B2B activity toward consumer-facing brand building. The CFO quantified spends related to sponsorship events at just under INR 5 crore during the quarter and described these as long-term investments to build IGI brand salience.

On the standalone India business, the company reported certification revenue of INR 2,792 million and EBITDA of INR 1,970 million, with an EBITDA margin of 68.8% versus 73.0% in the year-ago quarter. Management explained that as the company scales retail engagement in other geographies and influences markets to push IGI-certified stones, the India entity pays commissions to other geographies that source business leads. They also cited the IPL sponsorship impact as largely front-loaded.

Outlook and what to track

Management reiterated FY27 guidance of 15% revenue growth on the base business and 20% EBITDA growth, while noting that AGL could contribute an additional couple of percentage points to revenue growth. On margins, the CFO said consolidated EBITDA margin should be supported by operating leverage as volumes scale and indicated a potential improvement of at least 100 basis points by the end of the year.

From an operational standpoint, management highlighted investments in AI and machine learning to improve processing efficiency and turnaround times. When asked about turnaround time in India, management stated that a two to three day turnaround time is acceptable and is what the company strives for.

Two structural themes stood out across the presentation and call. First, IGI is leaning into the idea that certification intensity rises with scale, particularly for lab-grown diamonds as capacity expands and jewelry moves to SKU-level certification. Second, the company is broadening its certification footprint beyond diamonds through AGL.

At the same time, investors will likely track a few practical markers. Customer concentration in lab-grown manufacturing was acknowledged, with management stating that a limited number of large growers account for a significant portion of output. Investors may also watch how marketing and leadership investments translate into demand pull without diluting margins.

Overall, Q1 FY27 reflects strong financial translation of volume growth into margin expansion at the consolidated level, while also beginning to integrate AGL into a broader, longer-term story of expanding certification categories and geographies.
