IPO Digest — June 17, 2026: SENASIC Doubles on Debut, HKEX Bookbuilding Wave Builds

June 17 had one tradeable new listing, one A-share subscription, three fresh filing items, and a crowded Hong Kong bookbuilding queue. The investable action was concentrated in SENASIC: the wireless sensing SoC maker more than doubled on its first HKEX session while the mainland IPO tape stayed mostly at the filing and subscription stages.

At-a-glance table

Company	Market / board	June 17 status	Size / price	Business	Watchpoint
SENASIC / 琻捷电子 (06675)	HKEX Main Board	Priced and traded	HK$18.36 issue price; closed at HK$41.70, up 127.12%; gross proceeds about HK$980.55 million 1	Fabless wireless sensing SoC supplier for automotive, energy storage, industrial electronics and related edge-sensing applications 2	Strong retail heat met a still-lossmaking profile; adjusted loss narrowed to RMB31.9 million in 2025 but operating cash outflow remained RMB173.6 million 1
Jihechang / 吉和昌 (920193)	Beijing Stock Exchange	Priced, not yet traded; subscription ended today	RMB8.52 issue price; 28.00 million shares; 14.98x issue P/E; 1.26 million-share online subscription cap 3	BSE IPO candidate; the day’s only verified A-share new-share subscription in the main new-share calendar 3	Track allotment, payment and listing-date disclosure after the subscription window.
Anwen Technology Group / 安闻科技	SZSE Main Board	New prospectus disclosed / IPO application stage	Proposed public issue of up to 40.01 million shares; planned IPO use of proceeds totals about RMB2.005 billion (RMB20.05 亿元) across auto electronics production, Tianjin and Zhejiang capacity, R&D, digitalization and working capital 4	Automotive cockpit comfort and safety systems, including thermal comfort, posture comfort and sensing products 4	Scale of planned fundraising is large for an auto-parts supplier; order durability and customer concentration will matter in review.
Dalian Auto Tech / 大连奥托	SZSE ChiNext	New prospectus disclosed / IPO application stage	Proposed public issue of up to 20.7778 million shares; planned use of proceeds totals about RMB1.10 billion (RMB11.0 亿元) across Anhui and Dalian production bases, two R&D centers and working capital 5	Intelligent manufacturing and automotive body-in-white automation-line systems 5	ChiNext fit depends on whether the company can frame automotive automation as growth technology rather than cyclical capex exposure.
Borchien New Materials / 博迁新材 (605376.SH)	HKEX Main Board filing	H-share application filed	Fundraising amount not disclosed in the article; sponsor: Guotai Junan International 6	Electronic-grade metal powder supplier; 2025 share of the global MLCC nickel-powder supplier market was about 11.0% by revenue, ranking second globally, according to the cited Frost & Sullivan data 6	Another A+H-style materials name for the Hong Kong queue; valuation will likely lean on MLCC cycle expectations and powder-material margin durability.

HKEX: SENASIC supplied the day’s price action

SENASIC was the only verified HKEX debut in today’s tape. The stock priced at HK$18.36, raised gross proceeds of about HK$980.55 million, and closed its first session at HK$41.70, a 127.12% gain over the offer price 1. The first-day move also followed a heavily subscribed public tranche: separate coverage reported about 5,145x Hong Kong public subscription and 4.44x international placing demand 2.

The business is easy to place in this market: SENASIC sells wireless sensing SoCs, with products spanning smart tire chips, smart battery-cell chips and general-purpose sensing chips. The pitch is edge sensing for automotive and other physical-AI applications, but the financial profile still needs work. China Economic Net’s write-up, citing the prospectus, reported revenue of RMB223.5 million, RMB347.5 million and RMB477.9 million for 2023-2025, against annual losses of RMB355.8 million, RMB351.3 million and RMB330.6 million 1.

The immediate read-through: HK retail demand is still willing to pay for scarce hard-tech listings. The risk is that a first-day double can pull forward too much of the story before the company has shown operating profitability.

The A-share calendar showed no verified new debut in the sources checked; the main new-share item was Jihechang’s BSE subscription. Eastmoney’s new-share page listed Jihechang (920193) as today’s completed subscription at RMB8.52 per share, with 28.00 million shares offered and a 14.98x issue P/E 3. That places Jihechang in the priced-but-not-traded bucket until allotment and listing-date updates are released.

Two new SZSE filing items matter more for the forward pipeline than for near-term trading. Anwen Technology disclosed a Main Board prospectus with a proposed issue of up to 40.01 million shares and planned use of proceeds across automotive electronics production, R&D, digitalization and working capital; its business is automotive cockpit comfort and safety systems 4. Dalian Auto Tech disclosed a ChiNext prospectus with a proposed issue of up to 20.7778 million shares and about RMB1.10 billion (RMB11.0 亿元) in planned proceeds for production-base, R&D and working-capital projects 5.

Hong Kong pipeline: filings and a June 26 queue

Borchien New Materials added another H-share filing to the HKEX pipeline. Zhitong Finance reported that Jiangsu Borchien New Materials (605376.SH) filed for a Main Board listing on June 17, with Guotai Junan International as sole sponsor; the company is described as an electronic-grade metal-powder supplier, including MLCC nickel powder 6.

Hong Kong’s near-term listing queue also thickened. Daily Economic News reported that six companies started bookbuilding today and are expected to list on June 26: Lingyi iTech, SG Micro, Xinqi Micro, Zhongke Wenge, Ketu and MERDEKA GOLD-DRS. The same report put their expected combined fundraising at about HK$19.795 billion, and noted that three are A+H candidates, two are 18C specialist-technology issuers, and MERDEKA GOLD-DRS is an Indonesian issuer seeking a Hong Kong depositary-receipt secondary listing 7.

Four previously launched Hong Kong subscriptions remained active in the day’s IPO diary: Macu-Makco Pharma-B (2335), SEER (6106), Huajian Future-B (6132) and Senior Material (6067) 8. That makes the next week’s tape unusually sensitive to allocation results rather than just listing-day prints.

Watchpoints for the next issue

SENASIC aftermarket liquidity. A 127.12% first-day close sets a high reference point; the next useful data point is whether turnover and price hold after immediate retail demand cools.
Jihechang allotment and listing date. The subscription is complete, but it remains a priced, not-yet-traded A-share IPO until BSE listing arrangements are posted.
SZSE review framing. Anwen is an auto cockpit systems supplier seeking the Main Board; Dalian Auto is an industrial automation supplier seeking ChiNext. Their review questions should reveal how SZSE is treating automotive supply-chain cyclicality versus advanced-manufacturing narratives.
HKEX June 26 congestion. Six newly launched Hong Kong offerings plus four active subscriptions means allocation outcomes, cornerstone quality and final pricing could matter more than headline filing volume in the next few trading days.
