PT Timah Tbk (TINS), Indonesia’s state-owned tin mining titan, delivered a monumental financial performance for the first half of 2026, recording a staggering net profit of Rp2.7 trillion. This represented an extraordinary 805% year-on-year surge, significantly outpacing market consensus estimates, which had projected Rp3.9 trillion for the full year 2026. The half-year results alone captured 70% of that ambitious forecast, signaling a powerful upswing in the company’s fortunes.

A Half-Year of Explosive Growth and Margin Expansion

The remarkable bottom-line expansion was primarily fueled by an impressive growth in revenue, which climbed 147% year-on-year to Rp10.4 trillion during 1H26. TINS deftly capitalized on a favorable market, witnessing a substantial 52% year-on-year increase in the average selling price (ASP) of tin metal. Concurrently, the company’s sales volume experienced robust growth, jumping 85% year-on-year, demonstrating potent operational execution.

Crucially, this top-line acceleration translated directly into significant margin expansion. While revenue soared, the cost of goods sold (COGS) increased at a more modest pace of 89% year-on-year. This disparity allowed the gross profit margin to nearly double, reaching a robust 39% from 20% in 1H25. This formidable operational leverage cascaded down the income statement, catapulting the net profit margin to an impressive 26.1%, a stark contrast to the 7.1% reported in the same period last year.

Q2 2026: Navigating Dynamics with Resilience

Zooming into the second quarter of 2026, TINS reported a net profit of Rp1.2 trillion. While this figure represented a 19% quarter-on-quarter (QoQ) decrease, it still marked an exceptional 563% year-on-year (YoY) increase, reinforcing the underlying strength of the company’s strategic positioning.

Decoding the Quarterly Nuances

The sequential contraction in net profit during Q2 2026 stemmed primarily from a shift in sales dynamics. Sales volume dipped to 4,975 metric tons (MT), a 17% QoQ decline, even as tin metal production stood at 5,235 MT, a more moderate 7% QoQ decrease. This divergence led to a positive change in inventory value, turning from a negative Rp182 billion in 1Q26 to a positive Rp220 billion in 2Q26, indicating a build-up of stock.

Furthermore, other income for the quarter experienced a reversal, swinging to a negative Rp40 billion compared to a positive Rp37 billion in 1Q26. This shift was largely attributable to unitemized “other posts,” details of which can often be found in the comprehensive official financial reports.

Strategic Strength in a Volatile Commodity Landscape

TINS’s extraordinary half-year performance underscores its strong operational footing and strategic advantage in harnessing favorable commodity prices. The company’s ability to significantly expand margins, even amidst quarterly fluctuations in sales and production, positions it as a resilient player in the global tin market. As TINS navigates the ebb and flow of global demand and pricing, its robust H1 2026 results serve as a compelling testament to its enduring value proposition for investors.
