1.6T: The 'Violent' Stockpiling Before Dawn - A Deep Dive into Sunwave's Q1 Earnings

Last night, Sunwave (300502.SZ) unveiled its report card. Its full-year 2025 performance was epic, but the Q1 2026 profit fluctuations sent a shiver down many spines. Some saw the quarter-on-quarter profit decline and cried 'bomb,' while others saw the massive year-on-year surge and hailed it as 'invincible.'

However, in the eyes of professional investors, the sexiest part of this earnings report isn't in the income statement at all, but in a corner of the balance sheet.

I. The Hidden 'Offensive': A 39-Fold Surge in Prepayments

If you only look at net profit, Sunwave's Q1 might seem mediocre. But pay attention to an extremely abnormal data point: the company's prepayments skyrocketed from less than 17 million last quarter to 680 million this quarter, a staggering 39-fold increase!

In manufacturing, especially in the precision optical communication sector, what do prepayments signify?

Locking in Capacity: It means the company is placing frantic orders with upstream suppliers (like chip/component suppliers such as Hongchen Photonics) regardless of cost.

Order-Driven: Without confirmed orders, management would never dare to commit 700 million in real cash during Q1, a traditionally slow season.

This is far from a 'bomb'; it's clearly 'violent stockpiling.' Sunwave is hoarding so much raw material, obviously not to knit sweaters at home, but to meet the impending tidal wave of 1.6T deliveries.

II. The 'Smoke and Mirrors' of Profit: Forex and Mismatch

Why did revenue increase, yet profit seems 'a bit lacking'?

Forex Disturbance: Over 96% of revenue comes from overseas. The hundreds of millions in financial expenses on the Q1 statement are mostly paper losses from exchange rate fluctuations. Management also stated these are not realized losses and will reverse with future exchange rate movements.

Pacing Mismatch: The ramp-up pace of 1.6T products is slightly behind that of leading players like Zhongji Innolight. We are currently in a 'relay period' where older 800G products are in a price-cutting cycle, and new 1.6T products haven't yet been booked as revenue on a large scale.

III. 'Status Reshaping' in the 1.6T Era

What Sunwave is doing now is shifting from 'defensive to offensive.'

Construction in Progress +44.5%: Indicates capacity expansion is still accelerating.

Logical Mapping: When we place Sunwave within the global AI computing chain, the demand for 1.6T optical modules is rigid with the large-scale deployment of Blackwell architecture GPUs. Sunwave's current 'saturation-style' raw material reserve is precisely to avoid falling behind or being bottlenecked during the volume ramp-up in the second half of the year.

IV. Conclusion: Of Course, Choose to 'Forgive' Her

As some seasoned observers have said, facing such an earnings report, one should indeed choose to 'forgive.'

The so-called 'flaws'—forex losses, a slight quarter-on-quarter profit dip—are all short-term disturbances. The 'surge in prepayments' and 'doubling of contract liabilities' are the hardcore previews. Sunwave is telling the market with real cash: the AI wind hasn't stopped; a bigger wave is still ahead.

If you're still hung up on the few hundred million less in paper profit for Q1, you might miss the doubled starry sea of the upcoming 1.6T era.
